      <pubDate>Mon, 01 Jan 2018 16:01:23 +0800</pubDate>
      
      <guid>http://www.itspedia.com/post/jane-theme-preview/</guid>
      
        <description>&lt;p&gt;&lt;strong&gt;Markdown&lt;/strong&gt; is created by &lt;a href=&#34;http://daringfireball.net/&#34;&gt;Daring Fireball&lt;/a&gt;, the original guideline is &lt;a href=&#34;http://daringfireball.net/projects/markdown/syntax&#34;&gt;here&lt;/a&gt;. Its syntax, however, varies between different parsers or editors.&lt;/p&gt;
&lt;p&gt;Please note that HTML fragments in markdown source will be recognized but not parsed or rendered. Also, there may be small reformatting on the original markdown source code after saving.&lt;/p&gt;
&lt;h2 id=&#34;paragraph-and-line-breaks&#34;&gt;Paragraph and line breaks&lt;/h2&gt;
&lt;p&gt;A paragraph is simply one or more consecutive lines of text. In markdown source code, paragraphs are separated by more than one blank lines. In Typora, you only need to press &lt;code&gt;Return&lt;/code&gt; to create a new paragraph.&lt;/p&gt;
&lt;p&gt;Press &lt;code&gt;Shift&lt;/code&gt; + &lt;code&gt;Return&lt;/code&gt; to create a single line break. However, most markdown parser will ignore single line break, to make other markdown parsers recognize your line break, you can leave two whitespace at the end of the line, or insert &lt;code&gt;&amp;lt;br/&amp;gt;&lt;/code&gt;.&lt;/p&gt;
&lt;h2 id=&#34;headers&#34;&gt;Headers&lt;/h2&gt;
&lt;p&gt;Headers use 1-6 hash characters at the start of the line, corresponding to header levels 1-6. For example:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;# This is an H1

&lt;span style=&#34;color:#75715e&#34;&gt;## This is an H2
&lt;/span&gt;&lt;span style=&#34;color:#75715e&#34;&gt;&lt;/span&gt;
&lt;span style=&#34;color:#75715e&#34;&gt;###### This is an H6
&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;In typora, input ‘#’s followed by title content, and press &lt;code&gt;Return&lt;/code&gt; key will create a header.&lt;/p&gt;
&lt;h2 id=&#34;blockquotes&#34;&gt;Blockquotes&lt;/h2&gt;
&lt;p&gt;Markdown uses email-style &amp;gt; characters for block quoting. They are presented as:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;This is a blockquote with two paragraphs. This is first paragraph.&lt;/p&gt;
&lt;p&gt;This is second pragraph.Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.&lt;/p&gt;
&lt;p&gt;This is another blockquote with one paragraph. There is three empty line to seperate two blockquote.&lt;/p&gt;
&lt;p&gt;这是一段中文测试。&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;In typora, just input ‘&amp;gt;’ followed by quote contents a block quote is  generated. Typora will insert proper ‘&amp;gt;’ or line break for you. Block quote inside anther block quote is allowed by adding additional levels of ‘&amp;gt;’.&lt;/p&gt;
&lt;h2 id=&#34;lists&#34;&gt;Lists&lt;/h2&gt;
&lt;p&gt;Input &lt;code&gt;* list item 1&lt;/code&gt; will create an un-ordered list, the &lt;code&gt;*&lt;/code&gt; symbol can be replace with &lt;code&gt;+&lt;/code&gt; or &lt;code&gt;-&lt;/code&gt;.&lt;/p&gt;
&lt;p&gt;Input &lt;code&gt;1. list item 1&lt;/code&gt; will create an ordered list, their markdown source code is like:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Red&lt;/li&gt;
&lt;li&gt;Green&lt;/li&gt;
&lt;li&gt;Blue&lt;/li&gt;
&lt;/ul&gt;
&lt;ol&gt;
&lt;li&gt;Red&lt;/li&gt;
&lt;li&gt;Green&lt;/li&gt;
&lt;li&gt;Blue&lt;/li&gt;
&lt;/ol&gt;
&lt;h2 id=&#34;task-list&#34;&gt;Task List&lt;/h2&gt;
&lt;p&gt;Task lists are lists with items marked as either &lt;code&gt;[ ]&lt;/code&gt; or &lt;code&gt;[x]&lt;/code&gt; (incomplete or complete). For example:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;input disabled=&#34;&#34; type=&#34;checkbox&#34;&gt;a task list item&lt;/li&gt;
&lt;li&gt;&lt;input disabled=&#34;&#34; type=&#34;checkbox&#34;&gt;list syntax required&lt;/li&gt;
&lt;li&gt;&lt;input disabled=&#34;&#34; type=&#34;checkbox&#34;&gt;normal &lt;strong&gt;formatting&lt;/strong&gt;, @mentions, #1234 refs&lt;/li&gt;
&lt;li&gt;&lt;input disabled=&#34;&#34; type=&#34;checkbox&#34;&gt;incomplete&lt;/li&gt;
&lt;li&gt;&lt;input checked=&#34;&#34; disabled=&#34;&#34; type=&#34;checkbox&#34;&gt;completed&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;You can change the complete/incomplete state by click the checkbox before the item.&lt;/p&gt;
&lt;h2 id=&#34;syntax-highlighting&#34;&gt;Syntax Highlighting&lt;/h2&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-js&#34; data-lang=&#34;js&#34;&gt;&lt;span style=&#34;color:#66d9ef&#34;&gt;function&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;helloWorld&lt;/span&gt; () {
  &lt;span style=&#34;color:#a6e22e&#34;&gt;alert&lt;/span&gt;(&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Hello, World!&amp;#34;&lt;/span&gt;)
}
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-java&#34; data-lang=&#34;java&#34;&gt;&lt;span style=&#34;color:#66d9ef&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color:#66d9ef&#34;&gt;class&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;HelloWorld&lt;/span&gt; &lt;span style=&#34;color:#f92672&#34;&gt;{&lt;/span&gt;
  &lt;span style=&#34;color:#66d9ef&#34;&gt;public&lt;/span&gt; &lt;span style=&#34;color:#66d9ef&#34;&gt;static&lt;/span&gt; &lt;span style=&#34;color:#66d9ef&#34;&gt;void&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;main&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;(&lt;/span&gt;String&lt;span style=&#34;color:#f92672&#34;&gt;[&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;]&lt;/span&gt; args&lt;span style=&#34;color:#f92672&#34;&gt;)&lt;/span&gt; &lt;span style=&#34;color:#f92672&#34;&gt;{&lt;/span&gt;
    System&lt;span style=&#34;color:#f92672&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color:#a6e22e&#34;&gt;out&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;.&lt;/span&gt;&lt;span style=&#34;color:#a6e22e&#34;&gt;println&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;(&lt;/span&gt;&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Hello, World!&amp;#34;&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;)&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;;&lt;/span&gt;
  &lt;span style=&#34;color:#f92672&#34;&gt;}&lt;/span&gt;
&lt;span style=&#34;color:#f92672&#34;&gt;}&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;h2 id=&#34;math-blocks&#34;&gt;Math Blocks&lt;/h2&gt;
&lt;p&gt;You can render &lt;em&gt;LaTeX&lt;/em&gt; mathematical expressions using &lt;strong&gt;MathJax&lt;/strong&gt;.&lt;/p&gt;
&lt;p&gt;Input &lt;code&gt;$$&lt;/code&gt;, then press &amp;lsquo;Return&amp;rsquo; key will trigger an input field which accept &lt;em&gt;Tex/LaTex&lt;/em&gt; source. Following is an example:
$$
\mathbf{V}_1 \times \mathbf{V}_2 =  \begin{vmatrix}
\mathbf{i} &amp;amp; \mathbf{j} &amp;amp; \mathbf{k} \&lt;br&gt;
\frac{\partial X}{\partial u} &amp;amp;  \frac{\partial Y}{\partial u} &amp;amp; 0 \&lt;br&gt;
\frac{\partial X}{\partial v} &amp;amp;  \frac{\partial Y}{\partial v} &amp;amp; 0 \&lt;br&gt;
\end{vmatrix}
$$&lt;/p&gt;
&lt;p&gt;In markdown source file, math block is &lt;em&gt;LaTeX&lt;/em&gt; expression wrapped by ‘$$’ mark:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;$$
\mathbf{V}_1 \times \mathbf{V}_2 =  \begin{vmatrix}
\mathbf{i} &amp;amp; \mathbf{j} &amp;amp; \mathbf{k} \\
\frac{\partial X}{\partial u} &amp;amp;  \frac{\partial Y}{\partial u} &amp;amp; 0 \\
\frac{\partial X}{\partial v} &amp;amp;  \frac{\partial Y}{\partial v} &amp;amp; 0 \\
\end{vmatrix}
$$
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;h2 id=&#34;tables&#34;&gt;Tables&lt;/h2&gt;
&lt;p&gt;Input &lt;code&gt;| First Header  | Second Header |&lt;/code&gt; and press &lt;code&gt;return&lt;/code&gt; key will create a table with two column.&lt;/p&gt;
&lt;p&gt;After table is created, focus on that table will pop up a toolbar for table, where you can resize, align, or delete table. You can also use context menu to copy and add/delete column/row.&lt;/p&gt;
&lt;p&gt;Following descriptions can be skipped, as markdown source code for tables are generated by typora automatically.&lt;/p&gt;
&lt;p&gt;In markdown source code, they look like:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;| Name              | Markdown            | HTML tag             |

&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;&lt;code&gt;code&lt;/code&gt;&lt;/td&gt;
&lt;td&gt;&lt;code&gt;`code`&lt;/code&gt;&lt;/td&gt;
&lt;td&gt;&lt;code&gt;&amp;lt;code&amp;gt;&amp;lt;/code&amp;gt;&lt;/code&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;&lt;del&gt;Strikethrough&lt;/del&gt;&lt;/td&gt;
&lt;td&gt;&lt;code&gt;~~Strikethrough~~&lt;/code&gt;&lt;/td&gt;
&lt;td&gt;&lt;code&gt;&amp;lt;del&amp;gt;&amp;lt;/del&lt;/code&gt;&lt;/td&gt;

&lt;tr&gt;

&lt;td&gt;&lt;code&gt;&amp;lt;u&amp;gt;&amp;lt;/u&amp;gt;&lt;/code&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h2 id=&#34;footnotes&#34;&gt;Footnotes&lt;/h2&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;You can create footnotes like this[^footnote].

[^footnote]: Here is the &lt;span style=&#34;font-style:italic&#34;&gt;*text*&lt;/span&gt; of the &lt;span style=&#34;font-weight:bold&#34;&gt;**footnote&lt;/span&gt;&lt;span style=&#34;font-weight:bold&#34;&gt;**&lt;/span&gt;.
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;will produce:&lt;/p&gt;
&lt;p&gt;You can create footnotes like this&lt;sup id=&#34;fnref:1&#34;&gt;&lt;a href=&#34;#fn:1&#34; class=&#34;footnote-ref&#34; role=&#34;doc-noteref&#34;&gt;1&lt;/a&gt;&lt;/sup&gt;.&lt;/p&gt;
&lt;p&gt;Mouse on the ‘footnote’ superscript to see content of the footnote.&lt;/p&gt;
&lt;h2 id=&#34;horizontal-rules&#34;&gt;Horizontal Rules&lt;/h2&gt;
&lt;p&gt;Input &lt;code&gt;***&lt;/code&gt; or &lt;code&gt;---&lt;/code&gt; on a blank line and press &lt;code&gt;return&lt;/code&gt; will draw a horizontal line.&lt;/p&gt;
&lt;hr&gt;
&lt;h2 id=&#34;links&#34;&gt;Links&lt;/h2&gt;
&lt;p&gt;Markdown supports two style of links: inline and reference.&lt;/p&gt;
&lt;p&gt;In both styles, the link text is delimited by [square brackets].&lt;/p&gt;
&lt;p&gt;To create an inline link, use a set of regular parentheses immediately after the link text’s closing square bracket. Inside the parentheses, put the URL where you want the link to point, along with an optional title for the link, surrounded in quotes. For example:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;This is [&lt;span style=&#34;color:#f92672&#34;&gt;an example&lt;/span&gt;](&lt;span style=&#34;color:#a6e22e&#34;&gt;http://example.com/ &amp;#34;Title&amp;#34;&lt;/span&gt;) inline link.

[&lt;span style=&#34;color:#f92672&#34;&gt;This link&lt;/span&gt;](&lt;span style=&#34;color:#a6e22e&#34;&gt;http://example.net/&lt;/span&gt;) has no title attribute.
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;will produce:&lt;/p&gt;
&lt;p&gt;This is &lt;a href=&#34;http://example.com/%22Title%22&#34;&gt;an example&lt;/a&gt; inline link. (&lt;code&gt;&amp;lt;p&amp;gt;This is &amp;lt;a href=&amp;quot;http://example.com/&amp;quot; title=&amp;quot;Title&amp;quot;&amp;gt;&lt;/code&gt;)&lt;/p&gt;
&lt;p&gt;&lt;a href=&#34;http://example.net/&#34;&gt;This link&lt;/a&gt; has no title attribute. (&lt;code&gt;&amp;lt;p&amp;gt;&amp;lt;a href=&amp;quot;http://example.net/&amp;quot;&amp;gt;This link&amp;lt;/a&amp;gt; has no&lt;/code&gt;)&lt;/p&gt;
&lt;h3 id=&#34;internal-links&#34;&gt;Internal Links&lt;/h3&gt;
&lt;p&gt;&lt;strong&gt;You can set the href to headers&lt;/strong&gt;, which will create a bookmark that allow you to jump to that section after clicking. For example:&lt;/p&gt;
&lt;p&gt;Command(on Windows: Ctrl) + Click &lt;a href=&#34;#block-elements&#34;&gt;This link&lt;/a&gt; will jump to header &lt;code&gt;Block Elements&lt;/code&gt;. To see how to write that, please move cursor or click that link with &lt;code&gt;⌘&lt;/code&gt; key pressed to expand the element into markdown source.&lt;/p&gt;
&lt;h3 id=&#34;reference-links&#34;&gt;Reference Links&lt;/h3&gt;
&lt;p&gt;Reference-style links use a second set of square brackets, inside which you place a label of your choosing to identify the link:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;This is [an example][id] reference-style link.

Then, anywhere in the document, you define your link label like this, on a line by itself:

[id]: http://example.com/  &amp;#34;Optional Title Here&amp;#34;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;In typora, they will be rendered like:&lt;/p&gt;
&lt;p&gt;This is &lt;a href=&#34;http://example.com/&#34; title=&#34;Optional Title Here&#34;&gt;an example&lt;/a&gt; reference-style link.&lt;/p&gt;
&lt;p&gt;The implicit link name shortcut allows you to omit the name of the link, in which case the link text itself is used as the name. Just use an empty set of square brackets — e.g., to link the word “Google” to the google.com web site, you could simply write:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;[Google][]
And then define the link:

[Google]: http://google.com/
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;In typora click link will expand it for editing, command+click will open the hyperlink in web browser.&lt;/p&gt;
&lt;h2 id=&#34;urls&#34;&gt;URLs&lt;/h2&gt;
&lt;p&gt;Typora allows you to insert urls as links, wrapped by &lt;code&gt;&amp;lt;&lt;/code&gt;brackets&lt;code&gt;&amp;gt;&lt;/code&gt;.&lt;/p&gt;
&lt;p&gt;&lt;code&gt;&amp;lt;i@typora.io&amp;gt;&lt;/code&gt; becomes &lt;a href=&#34;mailto:i@typora.io&#34;&gt;i@typora.io&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;Typora will aslo auto link standard URLs. e.g: &lt;a href=&#34;http://www.google.com&#34;&gt;www.google.com&lt;/a&gt;.&lt;/p&gt;
&lt;h2 id=&#34;images&#34;&gt;Images&lt;/h2&gt;
&lt;p&gt;Image looks similar with links, but it requires an additional &lt;code&gt;!&lt;/code&gt; char before the start of link. Image syntax looks like this:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;![&lt;span style=&#34;color:#f92672&#34;&gt;Alt text&lt;/span&gt;](&lt;span style=&#34;color:#a6e22e&#34;&gt;/path/to/img.jpg&lt;/span&gt;)

![&lt;span style=&#34;color:#f92672&#34;&gt;Alt text&lt;/span&gt;](&lt;span style=&#34;color:#a6e22e&#34;&gt;/path/to/img.jpg &amp;#34;Optional title&amp;#34;&lt;/span&gt;)
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;You are able to use drag &amp;amp; drop to insert image from image file or we browser. And modify the markdown source code by clicking on the image. Relative path will be used if image is in same directory or sub-directory with current editing document when drag &amp;amp; drop.&lt;/p&gt;
&lt;p&gt;For more tips on images, please read &lt;a href=&#34;http://support.typora.io//Images/&#34;&gt;http://support.typora.io//Images/&lt;/a&gt;&lt;/p&gt;
&lt;h2 id=&#34;emphasis&#34;&gt;Emphasis&lt;/h2&gt;
&lt;p&gt;Markdown treats asterisks (&lt;code&gt;*&lt;/code&gt;) and underscores (&lt;code&gt;_&lt;/code&gt;) as indicators of emphasis. Text wrapped with one &lt;code&gt;*&lt;/code&gt; or &lt;code&gt;_&lt;/code&gt; will be wrapped with an HTML &lt;code&gt;&amp;lt;em&amp;gt;&lt;/code&gt; tag. E.g:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;*single asterisks*

&lt;span style=&#34;font-style:italic&#34;&gt;_single underscores_&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;output:&lt;/p&gt;
&lt;p&gt;&lt;em&gt;single asterisks&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;single underscores&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;GFM will ignores underscores in words, which is commonly used in code and names, like this:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;wow_great_stuff&lt;/p&gt;
&lt;p&gt;do_this_and_do_that_and_another_thing.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;To produce a literal asterisk or underscore at a position where it would otherwise be used as an emphasis delimiter, you can backslash escape it:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;\*this text is surrounded by literal asterisks\*
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;Typora recommends to use &lt;code&gt;*&lt;/code&gt; symbol.&lt;/p&gt;
&lt;h2 id=&#34;strong&#34;&gt;Strong&lt;/h2&gt;
&lt;p&gt;double *’s or _’s will be wrapped with an HTML &lt;code&gt;&amp;lt;strong&amp;gt;&lt;/code&gt; tag, e.g:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;**double asterisks**

&lt;span style=&#34;font-weight:bold&#34;&gt;__double underscores&lt;/span&gt;&lt;span style=&#34;font-weight:bold&#34;&gt;__&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;output:&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;double asterisks&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;double underscores&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Typora recommends to use &lt;code&gt;**&lt;/code&gt; symbol.&lt;/p&gt;
&lt;h2 id=&#34;code&#34;&gt;Code&lt;/h2&gt;
&lt;p&gt;To indicate a span of code, wrap it with backtick quotes (`). Unlike a pre-formatted code block, a code span indicates code within a normal paragraph. For example:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;Use the &lt;span style=&#34;color:#e6db74&#34;&gt;`printf()`&lt;/span&gt; function.
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;will produce:&lt;/p&gt;
&lt;p&gt;Use the &lt;code&gt;printf()&lt;/code&gt; function.&lt;/p&gt;
&lt;h2 id=&#34;strikethrough&#34;&gt;Strikethrough&lt;/h2&gt;
&lt;p&gt;GFM adds syntax to create strikethrough text, which is missing from standard Markdown.&lt;/p&gt;
&lt;p&gt;&lt;code&gt;~~Mistaken text.~~&lt;/code&gt; becomes &lt;del&gt;Mistaken text.&lt;/del&gt;&lt;/p&gt;
&lt;h2 id=&#34;underline&#34;&gt;Underline&lt;/h2&gt;
&lt;p&gt;Underline is powered by raw HTML.&lt;/p&gt;
&lt;p&gt;&lt;code&gt;&amp;lt;u&amp;gt;Underline&amp;lt;/u&amp;gt;&lt;/code&gt; becomes &lt;!-- raw HTML omitted --&gt;Underline&lt;!-- raw HTML omitted --&gt;.&lt;/p&gt;
&lt;h2 id=&#34;emoji-happy&#34;&gt;Emoji :happy:&lt;/h2&gt;
&lt;p&gt;Input emoji with syntax &lt;code&gt;😄&lt;/code&gt;.&lt;/p&gt;
&lt;p&gt;User can trigger auto-complete suggestions for emoji by pressing &lt;code&gt;ESC&lt;/code&gt; key, or trigger it automatically after enable it on preference panel. Also, input UTF8 emoji char directly from &lt;code&gt;Edit&lt;/code&gt; -&amp;gt; &lt;code&gt;Emoji &amp;amp; Symbols&lt;/code&gt; from menu bar is also supported.&lt;/p&gt;
&lt;h2 id=&#34;inline-math&#34;&gt;Inline Math&lt;/h2&gt;
&lt;p&gt;To use this feature, first, please enable it in &lt;code&gt;Preference&lt;/code&gt; Panel -&amp;gt; &lt;code&gt;Markdown&lt;/code&gt; Tab. Then use &lt;code&gt;$&lt;/code&gt; to wrap TeX command, for example: &lt;code&gt;$\lim_{x \to \infty} \exp(-x) = 0$&lt;/code&gt; will be rendered as LaTeX command.&lt;/p&gt;
&lt;p&gt;To trigger inline preview for inline math: input “$”, then press &lt;code&gt;ESC&lt;/code&gt; key, then input TeX command, a preview tooltip will be visible like below:&lt;/p&gt;
&lt;p&gt;&lt;!-- raw HTML omitted --&gt;&lt;/p&gt;
&lt;section class=&#34;footnotes&#34; role=&#34;doc-endnotes&#34;&gt;
&lt;hr&gt;
&lt;ol&gt;
&lt;li id=&#34;fn:1&#34; role=&#34;doc-endnote&#34;&gt;
&lt;p&gt;Here is the &lt;em&gt;text&lt;/em&gt; of the &lt;strong&gt;footnote&lt;/strong&gt;. &lt;a href=&#34;#fnref:1&#34; class=&#34;footnote-backref&#34; role=&#34;doc-backlink&#34;&gt;&amp;#x21a9;&amp;#xfe0e;&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;

&lt;h2 id=&#34;repeating-fractions&#34;&gt;Repeating fractions&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} \equiv 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\cdots} } } }
\]&lt;/span&gt;&lt;/p&gt;

\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;sum-of-a-series&#34;&gt;Sum of a Series&lt;/h2&gt;

&lt;p&gt;I broke up the next two examples into separate lines so it behaves better on a mobile phone. That&#39;s why they include \displaystyle.&lt;/p&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\displaystyle\sum_{i=1}^{k+1}i
\]&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\displaystyle= \frac{k(k+1)}{2}+k+1

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[

&lt;h2 id=&#34;arrows&#34;&gt;Arrows&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[

&lt;h2 id=&#34;calculus&#34;&gt;Calculus&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\int u \frac{dv}{dx}\,dx=uv-\int \frac{du}{dx}v\,dx

\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;cross-product&#34;&gt;Cross Product&lt;/h2&gt;

&lt;p&gt;This works in KaTeX, but the separation of fractions in this environment is not so good.&lt;/p&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} &amp; \mathbf{j} &amp; \mathbf{k} \\ \frac{\partial X}{\partial u} &amp; \frac{\partial Y}{\partial u} &amp; 0 \\ \frac{\partial X}{\partial v} &amp; \frac{\partial Y}{\partial v} &amp; 0 \end{vmatrix}
\]&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;Here&#39;s a workaround: make the fractions smaller with an extra class that targets the spans with &amp;quot;mfrac&amp;quot; class (makes no difference in the MathJax case):&lt;/p&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} &amp; \mathbf{j} &amp; \mathbf{k} \\ \frac{\partial X}{\partial u} &amp; \frac{\partial Y}{\partial u} &amp; 0 \\ \frac{\partial X}{\partial v} &amp; \frac{\partial Y}{\partial v} &amp; 0 \end{vmatrix}
\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;accents&#34;&gt;Accents&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[

\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;stretchy-brackets&#34;&gt;Stretchy brackets&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[

\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;evaluation-at-limits&#34;&gt;Evaluation at limits&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[

\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;case-definitions&#34;&gt;Case definitions&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[

\begin{aligned} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} &amp; = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} &amp; = 4 \pi \rho \\ \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} &amp; = \vec{\mathbf{0}} \\ \nabla \cdot \vec{\mathbf{B}} &amp; = 0 \end{aligned}
\]&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;These equations are quite cramped. We can add vertical spacing using (for example) [1em] after each line break (\). as you can see here:&lt;/p&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\begin{aligned} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} &amp; = \frac{4\pi}{c}\vec{\mathbf{j}} \\[1em] \nabla \cdot \vec{\mathbf{E}} &amp; = 4 \pi \rho \\[0.5em] \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} &amp; = \vec{\mathbf{0}} \\[1em] \nabla \cdot \vec{\mathbf{B}} &amp; = 0 \end{aligned}
\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;statistics&#34;&gt;Statistics&lt;/h2&gt;

&lt;p&gt;Definition of combination:&lt;/p&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\frac{n!}{k!(n-k)!} = {^n}C_k
{n \choose k}
\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;fractions-on-fractions&#34;&gt;Fractions on fractions&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\frac{\frac{1}{x}+\frac{1}{y}}{y-z}
\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;nth-root&#34;&gt;n-th root&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\sqrt[n]{1+x+x^2+x^3+\ldots}
\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;matrices&#34;&gt;Matrices&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
\begin{pmatrix} a_{11} &amp; a_{12} &amp; a_{13}\\ a_{21} &amp; a_{22} &amp; a_{23}\\ a_{31} &amp; a_{32} &amp; a_{33} \end{pmatrix}
\begin{bmatrix} 0 &amp; \cdots &amp; 0 \\ \vdots &amp; \ddots &amp; \vdots \\ 0 &amp; \cdots &amp; 0 \end{bmatrix}
\]&lt;/span&gt;&lt;/p&gt;

&lt;h2 id=&#34;punctuation&#34;&gt;Punctuation&lt;/h2&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
f(x) = \sqrt{1+x} \quad (x \ge -1)
f(x) \sim x^2 \quad (x\to\infty)
\]&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;Now with punctuation:&lt;/p&gt;

&lt;p&gt;&lt;span  class=&#34;math&#34;&gt;\[
f(x) = \sqrt{1+x}, \quad x \ge -1
f(x) \sim x^2, \quad x\to\infty
\]&lt;/span&gt;&lt;/p&gt;</description>

      <pubDate>Wed, 13 Feb 2019 16:01:23 +0800</pubDate>
      
      <guid>http://www.itspedia.com/post/architeture-dw-hall-of-fame.zh-cn/</guid>
      
        <description>&lt;p&gt;数据仓库领域，在业界有几位公认大牛，&lt;/p&gt;
&lt;h2 id=&#34;第一位-william-h-bill-inmon&#34;&gt;第一位 William H. (Bill) Inmon，&lt;/h2&gt;
&lt;p&gt;数据仓库之父，开山鼻祖，著书立说，培训演讲，出版了许多书，详见&lt;a href=&#34;https://en.wikipedia.org/wiki/Bill_Inmon#Publications&#34;&gt;wiki&lt;/a&gt;
我在这里推荐Building the Data Warehouse这本书，第&lt;strong&gt;四&lt;/strong&gt;版出版于2005。他推崇使用Corporate Information Factory（CIF）的数据建模方法（使用范式模型构建企业数据仓库+各维度模型构建的业务主题数据集市），最近在新的数据仓库架构和实施方面和后起之秀Dan Linstedt合作推动新的搭建数据仓库的方法论 Data Vault&lt;/p&gt;
&lt;h2 id=&#34;第二位-ralph-kimball&#34;&gt;第二位 Ralph Kimball&lt;/h2&gt;
&lt;p&gt;使用维度模型构建数据仓库的开创者（Dimensional Data Warehouse）。他起初在一段不短的时间内就这个构建数据仓库方法论和Inmon的CIF展开激烈论战，最终他的方法论获得业界广泛认可，成为业界构建数据仓库的事实标准。他的书专注于实际实现考虑，以toolkit主题的有三本，&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;The Data Warehouse Toolkit&lt;/li&gt;
&lt;li&gt;The Data Warehouse ETL Toolkit&lt;/li&gt;
&lt;li&gt;The Data Warehouse Lifecycle Toolkit&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;这三本书涵盖架构设计，模型设计，项目管理等多个主题，成为业界从业人员之必读。
这里不得不提&lt;a href=&#34;http://chrisadamson.com&#34;&gt;Chris Adamson&lt;/a&gt;，业界资深顾问，一个Ralph Kimball方法论的追随者，著有Star Schema The Complete Reference等。&lt;/p&gt;
&lt;h2 id=&#34;第三位-dan-linstedt&#34;&gt;第三位 Dan Linstedt&lt;/h2&gt;
&lt;p&gt;创新性地提出使用Data Vault建模方法来设计数据仓库模型，后续推出Data Vault 2.0构建数据仓库方法论，涵盖建模、项目管理、架构和实现等方面，通过成立商业联盟和认证培训等商业手段积极推广。&lt;/p&gt;

      <title>Shortcodes Preview</title>
      <link>http://www.itspedia.com/post/shortcodes-preview/</link>
      <pubDate>Sun, 04 Mar 2018 16:01:23 +0800</pubDate>
      
      <guid>http://www.itspedia.com/post/shortcodes-preview/</guid>
      
        <description>&lt;h2 id=&#34;what-a-shortcode-is&#34;&gt;What a Shortcode is&lt;/h2&gt;
&lt;p&gt;Hugo loves Markdown because of its simple content format, but there are times when Markdown falls short. Often, content authors are forced to add raw HTML (e.g., video &lt;code&gt;&amp;lt;iframes&amp;gt;&lt;/code&gt;) to Markdown content. We think this contradicts the beautiful simplicity of Markdown&amp;rsquo;s syntax.&lt;/p&gt;
&lt;p&gt;Hugo created &lt;strong&gt;shortcodes&lt;/strong&gt; to circumvent these limitations.&lt;/p&gt;
&lt;p&gt;A shortcode is a simple snippet inside a content file that Hugo will render using a predefined template. Note that shortcodes will not work in template files. If you need the type of drop-in functionality that shortcodes provide but in a template, you most likely want a [partial template][partials] instead.&lt;/p&gt;
&lt;p&gt;In addition to cleaner Markdown, shortcodes can be updated any time to reflect new classes, techniques, or standards. At the point of site generation, Hugo shortcodes will easily merge in your changes. You avoid a possibly complicated search and replace operation.&lt;/p&gt;
&lt;p&gt;More details: &lt;a href=&#34;https://gohugo.io/content-management/shortcodes/&#34;&gt;https://gohugo.io/content-management/shortcodes/&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;Over the past 24 hours I&amp;rsquo;ve been reflecting on my life &amp;amp; I&amp;rsquo;ve realized only one thing. I need a medieval battle axe.&lt;/p&gt;

        &lt;cite&gt;

        &lt;/cite&gt;
      
    
  &lt;/footer&gt;
&lt;/blockquote&gt;
&lt;/p&gt;
&lt;h2 id=&#34;music&#34;&gt;music&lt;/h2&gt;
&lt;!-- raw HTML omitted --&gt;
&lt;h2 id=&#34;gist&#34;&gt;gist&lt;/h2&gt;
&lt;p&gt;We can embed the gist in our content via username and gist ID pulled from the URL:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{&amp;lt; gist spf13 7896402 &amp;gt;}}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Display:&lt;/p&gt;
&lt;script type=&#34;application/javascript&#34; src=&#34;https://gist.github.com/spf13/7896402.js&#34;&gt;&lt;/script&gt;

&lt;h2 id=&#34;expand&#34;&gt;expand&lt;/h2&gt;
&lt;p&gt;The Expand shortcode displays an expandable/collapsible section of text on your page. Here is an example&lt;/p&gt;
&lt;details&gt;
  &lt;summary style=&#34;background-color:#f5f5f5;border:1px solid #ccc;padding:5px;&#34;&gt;
    Is this learn theme rocks ?
    
  &lt;/summary&gt;
  
Yes !.

&lt;/details&gt;

&lt;h3 id=&#34;usage&#34;&gt;Usage&lt;/h3&gt;
&lt;p&gt;this shortcode takes exactly one optional parameter to define the text that appears next to the expand/collapse icon. (default is “Click to expand”)&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{&amp;lt; expand &amp;quot;Is this learn theme rocks ?&amp;quot; &amp;gt;}}
Yes !.
{{&amp;lt; /expand &amp;gt;}}
&lt;/code&gt;&lt;/pre&gt;&lt;h2 id=&#34;youtube&#34;&gt;youtube&lt;/h2&gt;

&lt;div style=&#34;position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;&#34;&gt;
  &lt;iframe src=&#34;https://www.youtube.com/embed/w7Ft2ymGmfc&#34; style=&#34;position: absolute; top: 0; left: 0; width: 100%; height: 100%; border:0;&#34; allowfullscreen title=&#34;YouTube Video&#34;&gt;&lt;/iframe&gt;

      <title>Image Preview</title>
      <link>http://www.itspedia.com/post/image-preview/</link>
      <pubDate>Sat, 03 Mar 2018 16:01:23 +0800</pubDate>
      
      <guid>http://www.itspedia.com/post/image-preview/</guid>
      
        <description>&lt;p&gt;Thanks for &lt;a href=&#34;https://github.com/liwenyip/hugo-easy-gallery&#34;&gt;liwenyip/hugo-easy-gallery&lt;/a&gt; &amp;amp; &lt;a href=&#34;https://github.com/xianmin/hugo-theme-jane/pull/48&#34;&gt;Zebradil · Pull Request #48&lt;/a&gt; .&lt;/p&gt;
&lt;p&gt;Now, we could use &lt;code&gt;{{&amp;lt; gallery &amp;gt;}}&lt;/code&gt; shortcode in hugo-theme-jane.&lt;/p&gt;
&lt;h2 id=&#34;normal-image&#34;&gt;Normal Image&lt;/h2&gt;
&lt;p&gt;This is an image in &lt;code&gt;static/image&lt;/code&gt; folder.&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-markdown&#34; data-lang=&#34;markdown&#34;&gt;![&lt;span style=&#34;color:#f92672&#34;&gt;This is an image in `static/image` folder.&lt;/span&gt;](&lt;span style=&#34;color:#a6e22e&#34;&gt;/image/example.jpg&lt;/span&gt;)
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;h2 id=&#34;-figure--shortcode&#34;&gt;&lt;code&gt;{{&amp;lt; figure &amp;gt;}}&lt;/code&gt; shortcode&lt;/h2&gt;
&lt;h3 id=&#34;figure-image-with-title&#34;&gt;figure image with title&lt;/h3&gt;
&lt;pre&gt;&lt;code&gt;{{&amp;lt; figure src=&amp;quot;/image/example.jpg&amp;quot; title=&amp;quot;figure image with title&amp;quot; &amp;gt;}}
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;figure-image-with-caption&#34;&gt;figure image with caption&lt;/h3&gt;
&lt;pre&gt;&lt;code&gt;{{&amp;lt; figure src=&amp;quot;/image/example.jpg&amp;quot; caption=&amp;quot;figure image with caption figure image with caption figure image with caption figure image with caption figure image with caption&amp;quot; &amp;gt;}}
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;more--figure--shortcode-usage&#34;&gt;more &lt;code&gt;{{&amp;lt; figure &amp;gt;}}&lt;/code&gt; shortcode usage&lt;/h3&gt;
&lt;p&gt;Specifying your image files:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;{{&amp;lt; figure src=&amp;quot;thumb.jpg&amp;quot; link=&amp;quot;image.jpg&amp;quot; &amp;gt;}}&lt;/code&gt; will use &lt;code&gt;thumb.jpg&lt;/code&gt; for thumbnail and &lt;code&gt;image.jpg&lt;/code&gt; for lightbox&lt;/li&gt;
&lt;li&gt;&lt;code&gt;{{&amp;lt; figure src=&amp;quot;image.jpg&amp;quot; &amp;gt;}}&lt;/code&gt; or &lt;code&gt;{{&amp;lt; figure link=&amp;quot;image.jpg&amp;quot; &amp;gt;}}&lt;/code&gt; will use &lt;code&gt;image.jpg&lt;/code&gt; for both thumbnail and lightbox&lt;/li&gt;
&lt;li&gt;&lt;code&gt;{{&amp;lt; figure link=&amp;quot;image.jpg&amp;quot; thumb=&amp;quot;-small&amp;quot; &amp;gt;}}&lt;/code&gt; will use &lt;code&gt;image-small.jpg&lt;/code&gt; for thumbnail and &lt;code&gt;image.jpg&lt;/code&gt; for lightbox&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Optional parameters:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;All the &lt;a href=&#34;https://gohugo.io/extras/shortcodes&#34;&gt;features/parameters&lt;/a&gt; of Hugo&amp;rsquo;s built-in &lt;code&gt;figure&lt;/code&gt; shortcode work as normal, i.e. src, link, title, caption, class, attr (attribution), attrlink, alt&lt;/li&gt;
&lt;li&gt;&lt;code&gt;size&lt;/code&gt; (e.g. &lt;code&gt;size=&amp;quot;1024x768&amp;quot;&lt;/code&gt;) pre-defines the image size for PhotoSwipe. Use this option if you don&amp;rsquo;t want to pre-load the linked image to determine its size.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;class&lt;/code&gt; allows you to set any custom classes you want on the &lt;code&gt;&amp;lt;figure&amp;gt;&lt;/code&gt; tag.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Optional parameters for standalone &lt;code&gt;{{&amp;lt; figure &amp;gt;}}&lt;/code&gt; shortcodes only (i.e. don&amp;rsquo;t use on &lt;code&gt;{{&amp;lt; figure &amp;gt;}}&lt;/code&gt; inside &lt;code&gt;{{&amp;lt; gallery &amp;gt;}}&lt;/code&gt; - strange things may happen if you do):&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;caption-position&lt;/code&gt; and &lt;code&gt;caption-effect&lt;/code&gt; work the same as for the &lt;code&gt;{{&amp;lt; gallery &amp;gt;}}&lt;/code&gt; shortcode (see below).&lt;/li&gt;
&lt;li&gt;&lt;code&gt;width&lt;/code&gt; defines the &lt;a href=&#34;https://www.w3schools.com/cssref/pr_dim_max-width.asp&#34;&gt;&lt;code&gt;max-width&lt;/code&gt;&lt;/a&gt; of the image displayed on the page. If using a thumbnail for a standalone figure, set this equal to your thumbnail&amp;rsquo;s native width to make the captions behave properly (or feel free to come up with a better solution and submit a pull request :-)). Also use this option if you don&amp;rsquo;t have a thumbnail and you don&amp;rsquo;t want the hi-res image to take up the entire width of the screen/container.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;class=&amp;quot;no-photoswipe&amp;quot;&lt;/code&gt; prevents a &lt;code&gt;&amp;lt;figure&amp;gt;&lt;/code&gt; from being loaded into PhotoSwipe. If you click on the figure you&amp;rsquo;ll instead a good ol&amp;rsquo; fashioned hyperlink to a bigger image (or - if you haven&amp;rsquo;t specified a bigger image - the same one).&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id=&#34;-gallery--shortcode&#34;&gt;&lt;code&gt;{{&amp;lt; gallery &amp;gt;}}&lt;/code&gt; shortcode&lt;/h2&gt;
&lt;h3 id=&#34;simple-gallery&#34;&gt;simple gallery&lt;/h3&gt;
&lt;p&gt;To specify a directory of image files:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{&amp;lt; gallery dir=&amp;quot;/img/your-directory-of-images/&amp;quot; &amp;gt;}}
&lt;/code&gt;&lt;/pre&gt;&lt;ul&gt;
&lt;li&gt;The images are automatically captioned with the file name.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;[image].jpg&lt;/code&gt; is used for the hi-res image, and &lt;code&gt;[image]-thumb.jpg&lt;/code&gt; is used for the thumbnails.&lt;/li&gt;
&lt;li&gt;If &lt;code&gt;[image]-thumb.jpg&lt;/code&gt; doesn&amp;rsquo;t exist, then &lt;code&gt;[image].jpg&lt;/code&gt; will be used for both hi-res and thumbnail images.&lt;/li&gt;
&lt;li&gt;The default thumbnail suffix is &lt;code&gt;-thumb&lt;/code&gt;, but you can specify a different one e.g. &lt;code&gt;thumb=&amp;quot;-small&amp;quot;&lt;/code&gt; or &lt;code&gt;thumb=&amp;quot;_150x150&amp;quot;&lt;/code&gt;.&lt;/li&gt;
&lt;/ul&gt;
&lt;h3 id=&#34;to-specify-individual-image-files&#34;&gt;To specify individual image files&lt;/h3&gt;
&lt;pre&gt;&lt;code&gt;{{&amp;lt; gallery &amp;gt;}}
  {{&amp;lt; figure src=&amp;quot;image1.jpg&amp;quot; &amp;gt;}}
  {{&amp;lt; figure src=&amp;quot;image2.jpg&amp;quot; &amp;gt;}}
  {{&amp;lt; figure src=&amp;quot;image3.jpg&amp;quot; &amp;gt;}}
{{&amp;lt; /gallery &amp;gt;}}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;&lt;strong&gt;Optional parameters:&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;caption-position&lt;/code&gt; - determines the captions&amp;rsquo; position over the image. Options:
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;bottom&lt;/code&gt; (default)&lt;/li&gt;
&lt;li&gt;&lt;code&gt;center&lt;/code&gt;&lt;/li&gt;
&lt;li&gt;&lt;code&gt;none&lt;/code&gt; hides captions on the page (they will only show in PhotoSwipe)&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;&lt;code&gt;caption-effect&lt;/code&gt; - determines if/how captions appear upon hover. Options:
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;slide&lt;/code&gt; (default)&lt;/li&gt;
&lt;li&gt;&lt;code&gt;fade&lt;/code&gt;&lt;/li&gt;
&lt;li&gt;&lt;code&gt;none&lt;/code&gt; (captions always visible)&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;&lt;code&gt;hover-effect&lt;/code&gt; - determines if/how images change upon hover. Options:
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;zoom&lt;/code&gt; (default)&lt;/li&gt;
&lt;li&gt;&lt;code&gt;grow&lt;/code&gt;&lt;/li&gt;
&lt;li&gt;&lt;code&gt;shrink&lt;/code&gt;&lt;/li&gt;
&lt;li&gt;&lt;code&gt;slideup&lt;/code&gt;&lt;/li&gt;
&lt;li&gt;&lt;code&gt;slidedown&lt;/code&gt;&lt;/li&gt;
&lt;li&gt;&lt;code&gt;none&lt;/code&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;&lt;code&gt;hover-transition&lt;/code&gt; - determines if/how images change upon hover. Options:
&lt;ul&gt;
&lt;li&gt;not set - smooth transition (default)&lt;/li&gt;
&lt;li&gt;&lt;code&gt;none&lt;/code&gt; - hard transition&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;

      <title>English Creating a New Theme</title>
      <link>http://www.itspedia.com/post/english-preview/</link>
      <pubDate>Thu, 31 Aug 2017 15:43:48 +0800</pubDate>
      
      <guid>http://www.itspedia.com/post/english-preview/</guid>
      
        <description>&lt;h2 id=&#34;introduction&#34;&gt;Introduction&lt;/h2&gt;
&lt;p&gt;This tutorial will show you how to create a simple theme in Hugo. I assume that you are familiar with HTML, the bash command line, and that you are comfortable using Markdown to format content. I&amp;rsquo;ll explain how Hugo uses templates and how you can organize your templates to create a theme. I won&amp;rsquo;t cover using CSS to style your theme.&lt;/p&gt;
&lt;p&gt;We&amp;rsquo;ll start with creating a new site with a very basic template. Then we&amp;rsquo;ll add in a few pages and posts. With small variations on that, you will be able to create many different types of web sites.&lt;/p&gt;
&lt;p&gt;In this tutorial, commands that you enter will start with the &amp;ldquo;$&amp;rdquo; prompt. The output will follow. Lines that start with &amp;ldquo;#&amp;rdquo; are comments that I&amp;rsquo;ve added to explain a point. When I show updates to a file, the &amp;ldquo;:wq&amp;rdquo; on the last line means to save the file.&lt;/p&gt;
&lt;p&gt;Here&amp;rsquo;s an example:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;## this is a comment
$ echo this is a command
this is a command

## edit the file
$vi foo.md
+++
date = &amp;quot;2014-09-28&amp;quot;
title = &amp;quot;creating a new theme&amp;quot;
+++

bah and humbug
:wq

## show it
$ cat foo.md
+++
date = &amp;quot;2014-09-28&amp;quot;
title = &amp;quot;creating a new theme&amp;quot;
+++

bah and humbug
$
&lt;/code&gt;&lt;/pre&gt;&lt;h2 id=&#34;some-definitions&#34;&gt;Some Definitions&lt;/h2&gt;
&lt;p&gt;There are a few concepts that you need to understand before creating a theme.&lt;/p&gt;
&lt;h3 id=&#34;skins&#34;&gt;Skins&lt;/h3&gt;
&lt;p&gt;Skins are the files responsible for the look and feel of your site. It’s the CSS that controls colors and fonts, it’s the Javascript that determines actions and reactions. It’s also the rules that Hugo uses to transform your content into the HTML that the site will serve to visitors.&lt;/p&gt;
&lt;p&gt;You have two ways to create a skin. The simplest way is to create it in the &lt;code&gt;layouts/&lt;/code&gt; directory. If you do, then you don’t have to worry about configuring Hugo to recognize it. The first place that Hugo will look for rules and files is in the &lt;code&gt;layouts/&lt;/code&gt; directory so it will always find the skin.&lt;/p&gt;
&lt;p&gt;Your second choice is to create it in a sub-directory of the &lt;code&gt;themes/&lt;/code&gt; directory. If you do, then you must always tell Hugo where to search for the skin. It’s extra work, though, so why bother with it?&lt;/p&gt;
&lt;p&gt;The difference between creating a skin in &lt;code&gt;layouts/&lt;/code&gt; and creating it in &lt;code&gt;themes/&lt;/code&gt; is very subtle. A skin in &lt;code&gt;layouts/&lt;/code&gt; can’t be customized without updating the templates and static files that it is built from. A skin created in &lt;code&gt;themes/&lt;/code&gt;, on the other hand, can be and that makes it easier for other people to use it.&lt;/p&gt;
&lt;p&gt;The rest of this tutorial will call a skin created in the &lt;code&gt;themes/&lt;/code&gt; directory a theme.&lt;/p&gt;
&lt;p&gt;Note that you can use this tutorial to create a skin in the &lt;code&gt;layouts/&lt;/code&gt; directory if you wish to. The main difference will be that you won’t need to update the site’s configuration file to use a theme.&lt;/p&gt;
&lt;h3 id=&#34;the-home-page&#34;&gt;The Home Page&lt;/h3&gt;
&lt;p&gt;The home page, or landing page, is the first page that many visitors to a site see. It is the index.html file in the root directory of the web site. Since Hugo writes files to the public/ directory, our home page is public/index.html.&lt;/p&gt;
&lt;h3 id=&#34;site-configuration-file&#34;&gt;Site Configuration File&lt;/h3&gt;
&lt;p&gt;When Hugo runs, it looks for a configuration file that contains settings that override default values for the entire site. The file can use TOML, YAML, or JSON. I prefer to use TOML for my configuration files. If you prefer to use JSON or YAML, you’ll need to translate my examples. You’ll also need to change the name of the file since Hugo uses the extension to determine how to process it.&lt;/p&gt;
&lt;p&gt;Hugo translates Markdown files into HTML. By default, Hugo expects to find Markdown files in your &lt;code&gt;content/&lt;/code&gt; directory and template files in your &lt;code&gt;themes/&lt;/code&gt; directory. It will create HTML files in your &lt;code&gt;public/&lt;/code&gt; directory. You can change this by specifying alternate locations in the configuration file.&lt;/p&gt;
&lt;h3 id=&#34;content&#34;&gt;Content&lt;/h3&gt;
&lt;p&gt;Content is stored in text files that contain two sections. The first section is the “front matter,” which is the meta-information on the content. The second section contains Markdown that will be converted to HTML.&lt;/p&gt;
&lt;h4 id=&#34;front-matter&#34;&gt;Front Matter&lt;/h4&gt;
&lt;p&gt;The front matter is information about the content. Like the configuration file, it can be written in TOML, YAML, or JSON. Unlike the configuration file, Hugo doesn’t use the file’s extension to know the format. It looks for markers to signal the type. TOML is surrounded by “&lt;code&gt;+++&lt;/code&gt;”, YAML by “&lt;code&gt;---&lt;/code&gt;”, and JSON is enclosed in curly braces. I prefer to use TOML, so you’ll need to translate my examples if you prefer YAML or JSON.&lt;/p&gt;
&lt;p&gt;The information in the front matter is passed into the template before the content is rendered into HTML.&lt;/p&gt;
&lt;h4 id=&#34;markdown&#34;&gt;Markdown&lt;/h4&gt;
&lt;p&gt;Content is written in Markdown which makes it easier to create the content. Hugo runs the content through a Markdown engine to create the HTML which will be written to the output file.&lt;/p&gt;
&lt;h3 id=&#34;template-files&#34;&gt;Template Files&lt;/h3&gt;
&lt;p&gt;Hugo uses template files to render content into HTML. Template files are a bridge between the content and presentation. Rules in the template define what content is published, where it&amp;rsquo;s published to, and how it will rendered to the HTML file. The template guides the presentation by specifying the style to use.&lt;/p&gt;
&lt;p&gt;There are three types of templates: single, list, and partial. Each type takes a bit of content as input and transforms it based on the commands in the template.&lt;/p&gt;
&lt;p&gt;Hugo uses its knowledge of the content to find the template file used to render the content. If it can’t find a template that is an exact match for the content, it will shift up a level and search from there. It will continue to do so until it finds a matching template or runs out of templates to try. If it can’t find a template, it will use the default template for the site.&lt;/p&gt;
&lt;p&gt;Please note that you can use the front matter to influence Hugo’s choice of templates.&lt;/p&gt;
&lt;h4 id=&#34;single-template&#34;&gt;Single Template&lt;/h4&gt;
&lt;p&gt;A single template is used to render a single piece of content. For example, an article or post would be a single piece of content and use a single template.&lt;/p&gt;
&lt;h4 id=&#34;list-template&#34;&gt;List Template&lt;/h4&gt;
&lt;p&gt;A list template renders a group of related content. That could be a summary of recent postings or all articles in a category. List templates can contain multiple groups.&lt;/p&gt;
&lt;p&gt;The homepage template is a special type of list template. Hugo assumes that the home page of your site will act as the portal for the rest of the content in the site.&lt;/p&gt;
&lt;h4 id=&#34;partial-template&#34;&gt;Partial Template&lt;/h4&gt;
&lt;p&gt;A partial template is a template that can be included in other templates. Partial templates must be called using the “partial” template command. They are very handy for rolling up common behavior. For example, your site may have a banner that all pages use. Instead of copying the text of the banner into every single and list template, you could create a partial with the banner in it. That way if you decide to change the banner, you only have to change the partial template.&lt;/p&gt;
&lt;h2 id=&#34;create-a-new-site&#34;&gt;Create a New Site&lt;/h2&gt;
&lt;p&gt;Let&amp;rsquo;s use Hugo to create a new web site. I&amp;rsquo;m a Mac user, so I&amp;rsquo;ll create mine in my home directory, in the Sites folder. If you&amp;rsquo;re using Linux, you might have to create the folder first.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;new site&amp;rdquo; command will create a skeleton of a site. It will give you the basic directory structure and a useable configuration file.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ hugo new site ~/Sites/zafta
$ cd ~/Sites/zafta

It will also copy all static files (that&amp;rsquo;s everything that&amp;rsquo;s not content). Since we have an empty site, it won&amp;rsquo;t do much, but it will do it very quickly.&lt;/p&gt;

The lines that start with &amp;ldquo;WARN:&amp;rdquo; are warning messages. We&amp;rsquo;ll go over them later.&lt;/p&gt;
&lt;p&gt;We can verify that the command worked by looking at the directory again.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;See that new public/ directory? Hugo placed all generated content there. When you&amp;rsquo;re ready to publish your web site, that&amp;rsquo;s the place to start. For now, though, let&amp;rsquo;s just confirm that we have what we&amp;rsquo;d expect from a site with no content.&lt;/p&gt;

&lt;p&gt;Verify that you can run the built-in web server. It will dramatically shorten your development cycle if you do. Start it by running the &amp;ldquo;server&amp;rdquo; command. If it is successful, you will see output similar to the following:&lt;/p&gt;

Web Server is available at http://localhost:1313
Press Ctrl+C to stop
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Connect to the listed URL (it&amp;rsquo;s on the line that starts with &amp;ldquo;Web Server&amp;rdquo;). If everything is working correctly, you should get a page that shows the following:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;index.xml
sitemap.xml
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;That&amp;rsquo;s a listing of your public/ directory. Hugo didn&amp;rsquo;t create a home page because our site has no content. When there&amp;rsquo;s no index.html file in a directory, the server lists the files in the directory, which is what you should see in your browser.&lt;/p&gt;
&lt;p&gt;Let’s go back and look at those warnings again.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;WARN: 2014/09/29 Unable to locate layout: [index.html _default/list.html _default/single.html]
WARN: 2014/09/29 Unable to locate layout: [404.html]
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;That second warning is easier to explain. We haven’t created a template to be used to generate “page not found errors.” The 404 message is a topic for a separate tutorial.&lt;/p&gt;
&lt;p&gt;Now for the first warning. It is for the home page. You can tell because the first layout that it looked for was “index.html.” That’s only used by the home page.&lt;/p&gt;
&lt;p&gt;I like that the verbose flag causes Hugo to list the files that it&amp;rsquo;s searching for. For the home page, they are index.html, _default/list.html, and _default/single.html. There are some rules that we&amp;rsquo;ll cover later that explain the names and paths. For now, just remember that Hugo couldn&amp;rsquo;t find a template for the home page and it told you so.&lt;/p&gt;
&lt;p&gt;At this point, you&amp;rsquo;ve got a working installation and site that we can build upon. All that’s left is to add some content and a theme to display it.&lt;/p&gt;
&lt;h2 id=&#34;create-a-new-theme&#34;&gt;Create a New Theme&lt;/h2&gt;
&lt;p&gt;Hugo doesn&amp;rsquo;t ship with a default theme. There are a few available (I counted a dozen when I first installed Hugo) and Hugo comes with a command to create new themes.&lt;/p&gt;
&lt;p&gt;We&amp;rsquo;re going to create a new theme called &amp;ldquo;zafta.&amp;rdquo; Since the goal of this tutorial is to show you how to fill out the files to pull in your content, the theme will not contain any CSS. In other words, ugly but functional.&lt;/p&gt;
&lt;p&gt;All themes have opinions on content and layout. For example, Zafta uses &amp;ldquo;post&amp;rdquo; over &amp;ldquo;blog&amp;rdquo;. Strong opinions make for simpler templates but differing opinions make it tougher to use themes. When you build a theme, consider using the terms that other themes do.&lt;/p&gt;
&lt;h3 id=&#34;create-a-skeleton&#34;&gt;Create a Skeleton&lt;/h3&gt;
&lt;p&gt;Use the hugo &amp;ldquo;new&amp;rdquo; command to create the skeleton of a theme. This creates the directory structure and places empty files for you to fill out.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ hugo new theme zafta

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The skeleton includes templates (the files ending in .html), license file, a description of your theme (the theme.toml file), and an empty archetype.&lt;/p&gt;
&lt;p&gt;Please take a minute to fill out the theme.toml and LICENSE.md files. They&amp;rsquo;re optional, but if you&amp;rsquo;re going to be distributing your theme, it tells the world who to praise (or blame). It&amp;rsquo;s also nice to declare the license so that people will know how they can use the theme.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/theme.toml

## the bit that says &amp;quot;YOUR_NAME_HERE&amp;quot;
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Note that the the skeleton&amp;rsquo;s template files are empty. Don&amp;rsquo;t worry, we&amp;rsquo;ll be changing that shortly.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find themes/zafta -name &#39;*.html&#39; | xargs ls -l

$
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;update-the-configuration-file-to-use-the-theme&#34;&gt;Update the Configuration File to Use the Theme&lt;/h3&gt;
&lt;p&gt;Now that we&amp;rsquo;ve got a theme to work with, it&amp;rsquo;s a good idea to add the theme name to the configuration file. This is optional, because you can always add &amp;ldquo;-t zafta&amp;rdquo; on all your commands. I like to put it the configuration file because I like shorter command lines. If you don&amp;rsquo;t put it in the configuration file or specify it on the command line, you won&amp;rsquo;t use the template that you&amp;rsquo;re expecting to.&lt;/p&gt;
&lt;p&gt;Edit the file to add the theme, add a title for the site, and specify that all of our content will use the TOML format.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi config.toml
theme = &amp;quot;zafta&amp;quot;
baseurl = &amp;quot;&amp;quot;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Did you notice that the output is different? The warning message for the home page has disappeared and we have an additional information line saying that Hugo is syncing from the theme&amp;rsquo;s directory.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s check the public/ directory to see what Hugo&amp;rsquo;s created.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ ls -l public

-rw-r--r--  1 quoha  staff  243 Sep 29 17:56 sitemap.xml
$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Notice four things:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Hugo created a home page. This is the file public/index.html.&lt;/li&gt;
&lt;li&gt;Hugo created a css/ directory.&lt;/li&gt;
&lt;li&gt;Hugo created a js/ directory.&lt;/li&gt;
&lt;li&gt;Hugo claimed that it created 0 pages. It created a file and copied over static files, but didn&amp;rsquo;t create any pages. That&amp;rsquo;s because it considers a &amp;ldquo;page&amp;rdquo; to be a file created directly from a content file. It doesn&amp;rsquo;t count things like the index.html files that it creates automatically.&lt;/li&gt;
&lt;/ol&gt;
&lt;h4 id=&#34;the-home-page-1&#34;&gt;The Home Page&lt;/h4&gt;
&lt;p&gt;Hugo supports many different types of templates. The home page is special because it gets its own type of template and its own template file. The file, layouts/index.html, is used to generate the HTML for the home page. The Hugo documentation says that this is the only required template, but that depends. Hugo&amp;rsquo;s warning message shows that it looks for three different templates:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;WARN: 2014/09/29 Unable to locate layout: [index.html _default/list.html _default/single.html]
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;If it can&amp;rsquo;t find any of these, it completely skips creating the home page. We noticed that when we built the site without having a theme installed.&lt;/p&gt;
&lt;p&gt;When Hugo created our theme, it created an empty home page template. Now, when we build the site, Hugo finds the template and uses it to generate the HTML for the home page. Since the template file is empty, the HTML file is empty, too. If the template had any rules in it, then Hugo would have used them to generate the home page.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find . -name index.html | xargs ls -l
-rw-r--r--  1 quoha  staff  0 Sep 29 20:21 ./public/index.html
-rw-r--r--  1 quoha  staff  0 Sep 29 17:31 ./themes/zafta/layouts/index.html
$
&lt;/code&gt;&lt;/pre&gt;&lt;h4 id=&#34;the-magic-of-static&#34;&gt;The Magic of Static&lt;/h4&gt;
&lt;p&gt;Hugo does two things when generating the site. It uses templates to transform content into HTML and it copies static files into the site. Unlike content, static files are not transformed. They are copied exactly as they are.&lt;/p&gt;
&lt;p&gt;Hugo assumes that your site will use both CSS and JavaScript, so it creates directories in your theme to hold them. Remember opinions? Well, Hugo&amp;rsquo;s opinion is that you&amp;rsquo;ll store your CSS in a directory named css/ and your JavaScript in a directory named js/. If you don&amp;rsquo;t like that, you can change the directory names in your theme directory or jane delete them completely. Hugo&amp;rsquo;s nice enough to offer its opinion, then behave nicely if you disagree.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;h2 id=&#34;the-theme-development-cycle&#34;&gt;The Theme Development Cycle&lt;/h2&gt;
&lt;p&gt;When you&amp;rsquo;re working on a theme, you will make changes in the theme&amp;rsquo;s directory, rebuild the site, and check your changes in the browser. Hugo makes this very easy:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Purge the public/ directory.&lt;/li&gt;
&lt;li&gt;Run the built in web server in watch mode.&lt;/li&gt;
&lt;li&gt;Open your site in a browser.&lt;/li&gt;
&lt;li&gt;Update the theme.&lt;/li&gt;
&lt;li&gt;Glance at your browser window to see changes.&lt;/li&gt;
&lt;li&gt;Return to step 4.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;I’ll throw in one more opinion: never work on a theme on a live site. Always work on a copy of your site. Make changes to your theme, test them, then copy them up to your site. For added safety, use a tool like Git to keep a revision history of your content and your theme. Believe me when I say that it is too easy to lose both your mind and your changes.&lt;/p&gt;
&lt;p&gt;Check the main Hugo site for information on using Git with Hugo.&lt;/p&gt;
&lt;h3 id=&#34;purge-the-public-directory&#34;&gt;Purge the public/ Directory&lt;/h3&gt;
&lt;p&gt;When generating the site, Hugo will create new files and update existing ones in the &lt;code&gt;public/&lt;/code&gt; directory. It will not delete files that are no longer used. For example, files that were created in the wrong directory or with the wrong title will remain. If you leave them, you might get confused by them later. I recommend cleaning out your site prior to generating it.&lt;/p&gt;
&lt;p&gt;Note: If you&amp;rsquo;re building on an SSD, you should ignore this. Churning on a SSD can be costly.&lt;/p&gt;
&lt;h3 id=&#34;hugos-watch-option&#34;&gt;Hugo&amp;rsquo;s Watch Option&lt;/h3&gt;
&lt;p&gt;Hugo&amp;rsquo;s &amp;ldquo;&lt;code&gt;--watch&lt;/code&gt;&amp;rdquo; option will monitor the content/ and your theme directories for changes and rebuild the site automatically.&lt;/p&gt;
&lt;h3 id=&#34;live-reload&#34;&gt;Live Reload&lt;/h3&gt;
&lt;p&gt;Hugo&amp;rsquo;s built in web server supports live reload. As pages are saved on the server, the browser is told to refresh the page. Usually, this happens faster than you can say, &amp;ldquo;Wow, that&amp;rsquo;s totally amazing.&amp;rdquo;&lt;/p&gt;
&lt;h3 id=&#34;development-commands&#34;&gt;Development Commands&lt;/h3&gt;
&lt;p&gt;Use the following commands as the basis for your workflow.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;## purge old files. hugo will recreate the public directory.
##
$ rm -rf public
##
## run hugo in watch mode
##
$ hugo server --watch --verbose
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Here&amp;rsquo;s sample output showing Hugo detecting a change to the template for the home page. Once generated, the web browser automatically reloaded the page. I&amp;rsquo;ve said this before, it&amp;rsquo;s amazing.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;h2 id=&#34;update-the-home-page-template&#34;&gt;Update the Home Page Template&lt;/h2&gt;
&lt;p&gt;The home page is one of a few special pages that Hugo creates automatically. As mentioned earlier, it looks for one of three files in the theme&amp;rsquo;s layout/ directory:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;index.html&lt;/li&gt;
&lt;li&gt;_default/list.html&lt;/li&gt;
&lt;li&gt;_default/single.html&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;We could update one of the default templates, but a good design decision is to update the most specific template available. That&amp;rsquo;s not a hard and fast rule (in fact, we&amp;rsquo;ll break it a few times in this tutorial), but it is a good generalization.&lt;/p&gt;
&lt;h3 id=&#34;make-a-static-home-page&#34;&gt;Make a Static Home Page&lt;/h3&gt;
&lt;p&gt;Right now, that page is empty because we don&amp;rsquo;t have any content and we don&amp;rsquo;t have any logic in the template. Let&amp;rsquo;s change that by adding some text to the template.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
  &amp;lt;p&amp;gt;hugo says hello!&amp;lt;/p&amp;gt;
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
:wq

$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Build the web site and then verify the results.&lt;/p&gt;

&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
  &amp;lt;p&amp;gt;hugo says hello!&amp;lt;/p&amp;gt;
&amp;lt;script&amp;gt;document.write(&#39;&amp;lt;script src=&amp;quot;http://&#39;
        + (location.host || &#39;localhost&#39;).split(&#39;:&#39;)[0]
    + &#39;:1313/livereload.js?mindelay=10&amp;quot;&amp;gt;&amp;lt;/&#39;
        + &#39;script&amp;gt;&#39;)&amp;lt;/script&amp;gt;&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;When you use &lt;code&gt;--watch&lt;/code&gt;, the Live Reload script is added by Hugo. Look for live reload in the documentation to see what it does and how to disable it.&lt;/p&gt;
&lt;h3 id=&#34;build-a-dynamic-home-page&#34;&gt;Build a &amp;ldquo;Dynamic&amp;rdquo; Home Page&lt;/h3&gt;
&lt;p&gt;&amp;ldquo;Dynamic home page?&amp;rdquo; Hugo&amp;rsquo;s a static web site generator, so this seems an odd thing to say. I mean let&amp;rsquo;s have the home page automatically reflect the content in the site every time Hugo builds it. We&amp;rsquo;ll use iteration in the template to do that.&lt;/p&gt;
&lt;h4 id=&#34;create-new-posts&#34;&gt;Create New Posts&lt;/h4&gt;
&lt;p&gt;Now that we have the home page generating static content, let&amp;rsquo;s add some content to the site. We&amp;rsquo;ll display these posts as a list on the home page and on their own page, too.&lt;/p&gt;
&lt;p&gt;Hugo has a command to generate a skeleton post, just like it does for sites and themes.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ hugo --verbose new post/first.md
INFO: 2014/09/29 Using config file: /Users/quoha/Sites/zafta/config.toml

$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;That wasn&amp;rsquo;t very nice, was it?&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;new&amp;rdquo; command uses an archetype to create the post file. Hugo created an empty default archetype file, but that causes an error when there&amp;rsquo;s a theme. For me, the workaround was to create an archetypes file specifically for the post type.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The output says that it created 2 pages. Those are our new posts:&lt;/p&gt;

$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The new files are empty because because the templates used to generate the content are empty. The homepage doesn&amp;rsquo;t show the new content, either. We have to update the templates to add the posts.&lt;/p&gt;
&lt;h3 id=&#34;list-and-single-templates&#34;&gt;List and Single Templates&lt;/h3&gt;
&lt;p&gt;In Hugo, we have three major kinds of templates. There&amp;rsquo;s the home page template that we updated previously. It is used only by the home page. We also have &amp;ldquo;single&amp;rdquo; templates which are used to generate output for a single content file. We also have &amp;ldquo;list&amp;rdquo; templates that are used to group multiple pieces of content before generating output.&lt;/p&gt;
&lt;p&gt;Generally speaking, list templates are named &amp;ldquo;list.html&amp;rdquo; and single templates are named &amp;ldquo;single.html.&amp;rdquo;&lt;/p&gt;
&lt;p&gt;There are three other types of templates: partials, content views, and terms. We will not go into much detail on these.&lt;/p&gt;
&lt;h3 id=&#34;add-content-to-the-homepage&#34;&gt;Add Content to the Homepage&lt;/h3&gt;
&lt;p&gt;The home page will contain a list of posts. Let&amp;rsquo;s update its template to add the posts that we just created. The logic in the template will run every time we build the site.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
  {{ range first 10 .Data.Pages }}
    &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  {{ end }}
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
:wq

$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Hugo uses the Go template engine. That engine scans the template files for commands which are enclosed between &amp;ldquo;{{&amp;rdquo; and &amp;ldquo;}}&amp;quot;. In our template, the commands are:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;range&lt;/li&gt;
&lt;li&gt;.Title&lt;/li&gt;
&lt;li&gt;end&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;The &amp;ldquo;range&amp;rdquo; command is an iterator. We&amp;rsquo;re going to use it to go through the first ten pages. Every HTML file that Hugo creates is treated as a page, so looping through the list of pages will look at every file that will be created.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;.Title&amp;rdquo; command prints the value of the &amp;ldquo;title&amp;rdquo; variable. Hugo pulls it from the front matter in the Markdown file.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;end&amp;rdquo; command signals the end of the range iterator. The engine loops back to the top of the iteration when it finds &amp;ldquo;end.&amp;rdquo; Everything between the &amp;ldquo;range&amp;rdquo; and &amp;ldquo;end&amp;rdquo; is evaluated every time the engine goes through the iteration. In this file, that would cause the title from the first ten pages to be output as heading level one.&lt;/p&gt;
&lt;p&gt;It&amp;rsquo;s helpful to remember that some variables, like .Data, are created before any output files. Hugo loads every content file into the variable and then gives the template a chance to process before creating the HTML files.&lt;/p&gt;
&lt;p&gt;Build the web site and then verify the results.&lt;/p&gt;

&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Congratulations, the home page shows the title of the two posts. The posts themselves are still empty, but let&amp;rsquo;s take a moment to appreciate what we&amp;rsquo;ve done. Your template now generates output dynamically. Believe it or not, by inserting the range command inside of those curly braces, you&amp;rsquo;ve learned everything you need to know to build a theme. All that&amp;rsquo;s really left is understanding which template will be used to generate each content file and becoming familiar with the commands for the template engine.&lt;/p&gt;
&lt;p&gt;And, if that were entirely true, this tutorial would be much shorter. There are a few things to know that will make creating a new template much easier. Don&amp;rsquo;t worry, though, that&amp;rsquo;s all to come.&lt;/p&gt;
&lt;h3 id=&#34;add-content-to-the-posts&#34;&gt;Add Content to the Posts&lt;/h3&gt;
&lt;p&gt;We&amp;rsquo;re working with posts, which are in the content/post/ directory. That means that their section is &amp;ldquo;post&amp;rdquo; (and if we don&amp;rsquo;t do something weird, their type is also &amp;ldquo;post&amp;rdquo;).&lt;/p&gt;
&lt;p&gt;Hugo uses the section and type to find the template file for every piece of content. Hugo will first look for a template file that matches the section or type name. If it can&amp;rsquo;t find one, then it will look in the _default/ directory. There are some twists that we&amp;rsquo;ll cover when we get to categories and tags, but for now we can assume that Hugo will try post/single.html, then _default/single.html.&lt;/p&gt;
&lt;p&gt;Now that we know the search rule, let&amp;rsquo;s see what we actually have available:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find themes/zafta -name single.html | xargs ls -l
-rw-r--r--  1 quoha  staff  132 Sep 29 17:31 themes/zafta/layouts/_default/single.html
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;We could create a new template, post/single.html, or change the default. Since we don&amp;rsquo;t know of any other content types, let&amp;rsquo;s start with updating the default.&lt;/p&gt;
&lt;p&gt;Remember, any content that we haven&amp;rsquo;t created a template for will end up using this template. That can be good or bad. Bad because I know that we&amp;rsquo;re going to be adding different types of content and we&amp;rsquo;re going to end up undoing some of the changes we&amp;rsquo;ve made. It&amp;rsquo;s good because we&amp;rsquo;ll be able to see immediate results. It&amp;rsquo;s also good to start here because we can start to build the basic layout for the site. As we add more content types, we&amp;rsquo;ll refactor this file and move logic around. Hugo makes that fairly painless, so we&amp;rsquo;ll accept the cost and proceed.&lt;/p&gt;
&lt;p&gt;Please see the Hugo documentation on template rendering for all the details on determining which template to use. And, as the docs mention, if you&amp;rsquo;re building a single page application (SPA) web site, you can delete all of the other templates and work with just the default single page. That&amp;rsquo;s a refreshing amount of joy right there.&lt;/p&gt;
&lt;h4 id=&#34;update-the-template-file&#34;&gt;Update the Template File&lt;/h4&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/_default/single.html

    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;/post/second/&amp;quot;&amp;gt;second&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
 
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;/post/first/&amp;quot;&amp;gt;first&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
 
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;

$
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;create-a-post-listing&#34;&gt;Create a Post Listing&lt;/h3&gt;
&lt;p&gt;We have the posts displaying on the home page and on their own page. We also have a file public/post/index.html that is empty. Let&amp;rsquo;s make it show a list of all posts (not just the first ten).&lt;/p&gt;
&lt;p&gt;We need to decide which template to update. This will be a listing, so it should be a list template. Let&amp;rsquo;s take a quick look and see which list templates are available.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find themes/zafta -name list.html | xargs ls -l
-rw-r--r--  1 quoha  staff  0 Sep 29 17:31 themes/zafta/layouts/_default/list.html
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;As with the single post, we have to decide to update _default/list.html or create post/list.html. We still don&amp;rsquo;t have multiple content types, so let&amp;rsquo;s stay consistent and update the default list template.&lt;/p&gt;
&lt;h2 id=&#34;creating-top-level-pages&#34;&gt;Creating Top Level Pages&lt;/h2&gt;
&lt;p&gt;Let&amp;rsquo;s add an &amp;ldquo;about&amp;rdquo; page and display it at the top level (as opposed to a sub-level like we did with posts).&lt;/p&gt;
&lt;p&gt;The default in Hugo is to use the directory structure of the content/ directory to guide the location of the generated html in the public/ directory. Let&amp;rsquo;s verify that by creating an &amp;ldquo;about&amp;rdquo; page at the top level:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi content/about.md
+++
title = &amp;quot;about&amp;quot;
description = &amp;quot;about this site&amp;quot;
date = &amp;quot;2014-09-27&amp;quot;
slug = &amp;quot;about time&amp;quot;
+++

## about us

i&#39;m speechless
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find public -name &#39;*.html&#39; | xargs ls -l
-rw-rw-r--  1 mdhender  staff   334 Sep 27 15:08 public/about-time/index.html

-rw-rw-r--  1 mdhender  staff   342 Sep 27 15:08 public/post/second-post/index.html
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Notice that the page wasn&amp;rsquo;t created at the top level. It was created in a sub-directory named &amp;lsquo;about-time/&#39;. That name came from our slug. Hugo will use the slug to name the generated content. It&amp;rsquo;s a reasonable default, by the way, but we can learn a few things by fighting it for this file.&lt;/p&gt;
&lt;p&gt;One other thing. Take a look at the home page.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ cat public/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/post/theme/&amp;quot;&amp;gt;creating a new theme&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/about-time/&amp;quot;&amp;gt;about&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/post/second-post/&amp;quot;&amp;gt;second&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/post/first-post/&amp;quot;&amp;gt;first&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
&amp;lt;script&amp;gt;document.write(&#39;&amp;lt;script src=&amp;quot;http://&#39;
        + (location.host || &#39;localhost&#39;).split(&#39;:&#39;)[0]
		+ &#39;:1313/livereload.js?mindelay=10&amp;quot;&amp;gt;&amp;lt;/&#39;
        + &#39;script&amp;gt;&#39;)&amp;lt;/script&amp;gt;&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Notice that the &amp;ldquo;about&amp;rdquo; link is listed with the posts? That&amp;rsquo;s not desirable, so let&amp;rsquo;s change that first.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
  &amp;lt;h1&amp;gt;posts&amp;lt;/h1&amp;gt;
  {{ range first 10 .Data.Pages }}
    {{ if eq .Type &amp;quot;post&amp;quot;}}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Title }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}

  &amp;lt;h1&amp;gt;pages&amp;lt;/h1&amp;gt;
  {{ range .Data.Pages }}
    {{ if eq .Type &amp;quot;page&amp;quot; }}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Title }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The home page has two sections, posts and pages, and each section has the right set of headings and links in it.&lt;/p&gt;
&lt;p&gt;But, that about page still renders to about-time/index.html.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find public -name &#39;*.html&#39; | xargs ls -l
-rw-rw-r--  1 mdhender  staff    334 Sep 27 15:33 public/about-time/index.html

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Knowing that hugo is using the slug to generate the file name, the simplest solution is to change the slug. Let&amp;rsquo;s do it the hard way and change the permalink in the configuration file.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi config.toml
[permalinks]
	page = &amp;quot;/:title/&amp;quot;
	about = &amp;quot;/:filename/&amp;quot;
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify that this didn&amp;rsquo;t work. Hugo lets &amp;ldquo;slug&amp;rdquo; or &amp;ldquo;URL&amp;rdquo; override the permalinks setting in the configuration file. Go ahead and comment out the slug in content/about.md, then generate the web site to get it to be created in the right place.&lt;/p&gt;
&lt;h2 id=&#34;sharing-templates&#34;&gt;Sharing Templates&lt;/h2&gt;
&lt;p&gt;If you&amp;rsquo;ve been following along, you probably noticed that posts have titles in the browser and the home page doesn&amp;rsquo;t. That&amp;rsquo;s because we didn&amp;rsquo;t put the title in the home page&amp;rsquo;s template (layouts/index.html). That&amp;rsquo;s an easy thing to do, but let&amp;rsquo;s look at a different option.&lt;/p&gt;
&lt;p&gt;We can put the common bits into a shared template that&amp;rsquo;s stored in the themes/zafta/layouts/partials/ directory.&lt;/p&gt;
&lt;h3 id=&#34;create-the-header-and-footer-partials&#34;&gt;Create the Header and Footer Partials&lt;/h3&gt;
&lt;p&gt;In Hugo, a partial is a sugar-coated template. Normally a template reference has a path specified. Partials are different. Hugo searches for them along a TODO defined search path. This makes it easier for end-users to override the theme&amp;rsquo;s presentation.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/partials/header.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;head&amp;gt;
	&amp;lt;title&amp;gt;{{ .Title }}&amp;lt;/title&amp;gt;
&amp;lt;/head&amp;gt;
&amp;lt;body&amp;gt;
:wq

$ vi themes/zafta/layouts/partials/footer.html
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;update-the-home-page-template-to-use-the-partials&#34;&gt;Update the Home Page Template to Use the Partials&lt;/h3&gt;
&lt;p&gt;The most noticeable difference between a template call and a partials call is the lack of path:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ template &amp;quot;theme/partials/header.html&amp;quot; . }}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;versus&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ partial &amp;quot;header.html&amp;quot; . }}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Both pass in the context.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s change the home page template to use these new partials.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;posts&amp;lt;/h1&amp;gt;
  {{ range first 10 .Data.Pages }}
    {{ if eq .Type &amp;quot;post&amp;quot;}}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Title }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}

  &amp;lt;h1&amp;gt;pages&amp;lt;/h1&amp;gt;
  {{ range .Data.Pages }}
    {{ if or (eq .Type &amp;quot;page&amp;quot;) (eq .Type &amp;quot;about&amp;quot;) }}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Type }} - {{ .Title }} - {{ .RelPermalink }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The title on the home page is now &amp;ldquo;your title here&amp;rdquo;, which comes from the &amp;ldquo;title&amp;rdquo; variable in the config.toml file.&lt;/p&gt;
&lt;h3 id=&#34;update-the-default-single-template-to-use-the-partials&#34;&gt;Update the Default Single Template to Use the Partials&lt;/h3&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/_default/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The title on the posts and the about page should both reflect the value in the markdown file.&lt;/p&gt;
&lt;h2 id=&#34;add-date-published-to-posts&#34;&gt;Add “Date Published” to Posts&lt;/h2&gt;
&lt;p&gt;It&amp;rsquo;s common to have posts display the date that they were written or published, so let&amp;rsquo;s add that. The front matter of our posts has a variable named &amp;ldquo;date.&amp;rdquo; It&amp;rsquo;s usually the date the content was created, but let&amp;rsquo;s pretend that&amp;rsquo;s the value we want to display.&lt;/p&gt;
&lt;h3 id=&#34;add-date-published-to-the-template&#34;&gt;Add “Date Published” to the Template&lt;/h3&gt;
&lt;p&gt;We&amp;rsquo;ll start by updating the template used to render the posts. The template code will look like:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ .Date.Format &amp;quot;Mon, Jan 2, 2006&amp;quot; }}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Posts use the default single template, so we&amp;rsquo;ll change that file.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/_default/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  &amp;lt;h2&amp;gt;{{ .Date.Format &amp;quot;Mon, Jan 2, 2006&amp;quot; }}&amp;lt;/h2&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The posts now have the date displayed in them. There&amp;rsquo;s a problem, though. The &amp;ldquo;about&amp;rdquo; page also has the date displayed.&lt;/p&gt;
&lt;p&gt;As usual, there are a couple of ways to make the date display only on posts. We could do an &amp;ldquo;if&amp;rdquo; statement like we did on the home page. Another way would be to create a separate template for posts.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;if&amp;rdquo; solution works for sites that have just a couple of content types. It aligns with the principle of &amp;ldquo;code for today,&amp;rdquo; too.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s assume, though, that we&amp;rsquo;ve made our site so complex that we feel we have to create a new template type. In Hugo-speak, we&amp;rsquo;re going to create a section template.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s restore the default single template before we forget.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ mkdir themes/zafta/layouts/post
$ vi themes/zafta/layouts/_default/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Now we&amp;rsquo;ll update the post&amp;rsquo;s version of the single template. If you remember Hugo&amp;rsquo;s rules, the template engine will use this version over the default.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/post/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  &amp;lt;h2&amp;gt;{{ .Date.Format &amp;quot;Mon, Jan 2, 2006&amp;quot; }}&amp;lt;/h2&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Note that we removed the date logic from the default template and put it in the post template. Generate the web site and verify the results. Posts have dates and the about page doesn&amp;rsquo;t.&lt;/p&gt;
&lt;h3 id=&#34;dont-repeat-yourself&#34;&gt;Don&amp;rsquo;t Repeat Yourself&lt;/h3&gt;
&lt;p&gt;DRY is a good design goal and Hugo does a great job supporting it. Part of the art of a good template is knowing when to add a new template and when to update an existing one. While you&amp;rsquo;re figuring that out, accept that you&amp;rsquo;ll be doing some refactoring. Hugo makes that easy and fast, so it&amp;rsquo;s okay to delay splitting up a template.&lt;/p&gt;</description>

      <title>Creating a New Theme</title>
      <link>http://www.itspedia.com/post/creating-a-new-theme/</link>
      <pubDate>Sun, 28 Sep 2014 00:00:00 +0000</pubDate>
      
      <guid>http://www.itspedia.com/post/creating-a-new-theme/</guid>
      
        <description>&lt;h2 id=&#34;introduction&#34;&gt;Introduction&lt;/h2&gt;
&lt;p&gt;This tutorial will show you how to create a simple theme in Hugo. I assume that you are familiar with HTML, the bash command line, and that you are comfortable using Markdown to format content. I&amp;rsquo;ll explain how Hugo uses templates and how you can organize your templates to create a theme. I won&amp;rsquo;t cover using CSS to style your theme.&lt;/p&gt;
&lt;p&gt;We&amp;rsquo;ll start with creating a new site with a very basic template. Then we&amp;rsquo;ll add in a few pages and posts. With small variations on that, you will be able to create many different types of web sites.&lt;/p&gt;
&lt;p&gt;In this tutorial, commands that you enter will start with the &amp;ldquo;$&amp;rdquo; prompt. The output will follow. Lines that start with &amp;ldquo;#&amp;rdquo; are comments that I&amp;rsquo;ve added to explain a point. When I show updates to a file, the &amp;ldquo;:wq&amp;rdquo; on the last line means to save the file.&lt;/p&gt;
&lt;p&gt;Here&amp;rsquo;s an example:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;## this is a comment
$ echo this is a command
this is a command

## edit the file
$vi foo.md
+++
date = &amp;quot;2014-09-28&amp;quot;
title = &amp;quot;creating a new theme&amp;quot;
+++

bah and humbug
:wq

## show it
$ cat foo.md
+++
date = &amp;quot;2014-09-28&amp;quot;
title = &amp;quot;creating a new theme&amp;quot;
+++

bah and humbug
$
&lt;/code&gt;&lt;/pre&gt;&lt;h2 id=&#34;some-definitions&#34;&gt;Some Definitions&lt;/h2&gt;
&lt;p&gt;There are a few concepts that you need to understand before creating a theme.&lt;/p&gt;
&lt;h3 id=&#34;skins&#34;&gt;Skins&lt;/h3&gt;
&lt;p&gt;Skins are the files responsible for the look and feel of your site. It’s the CSS that controls colors and fonts, it’s the Javascript that determines actions and reactions. It’s also the rules that Hugo uses to transform your content into the HTML that the site will serve to visitors.&lt;/p&gt;
&lt;p&gt;You have two ways to create a skin. The simplest way is to create it in the &lt;code&gt;layouts/&lt;/code&gt; directory. If you do, then you don’t have to worry about configuring Hugo to recognize it. The first place that Hugo will look for rules and files is in the &lt;code&gt;layouts/&lt;/code&gt; directory so it will always find the skin.&lt;/p&gt;
&lt;p&gt;Your second choice is to create it in a sub-directory of the &lt;code&gt;themes/&lt;/code&gt; directory. If you do, then you must always tell Hugo where to search for the skin. It’s extra work, though, so why bother with it?&lt;/p&gt;
&lt;p&gt;The difference between creating a skin in &lt;code&gt;layouts/&lt;/code&gt; and creating it in &lt;code&gt;themes/&lt;/code&gt; is very subtle. A skin in &lt;code&gt;layouts/&lt;/code&gt; can’t be customized without updating the templates and static files that it is built from. A skin created in &lt;code&gt;themes/&lt;/code&gt;, on the other hand, can be and that makes it easier for other people to use it.&lt;/p&gt;
&lt;p&gt;The rest of this tutorial will call a skin created in the &lt;code&gt;themes/&lt;/code&gt; directory a theme.&lt;/p&gt;
&lt;p&gt;Note that you can use this tutorial to create a skin in the &lt;code&gt;layouts/&lt;/code&gt; directory if you wish to. The main difference will be that you won’t need to update the site’s configuration file to use a theme.&lt;/p&gt;
&lt;h3 id=&#34;the-home-page&#34;&gt;The Home Page&lt;/h3&gt;
&lt;p&gt;The home page, or landing page, is the first page that many visitors to a site see. It is the index.html file in the root directory of the web site. Since Hugo writes files to the public/ directory, our home page is public/index.html.&lt;/p&gt;
&lt;h3 id=&#34;site-configuration-file&#34;&gt;Site Configuration File&lt;/h3&gt;
&lt;p&gt;When Hugo runs, it looks for a configuration file that contains settings that override default values for the entire site. The file can use TOML, YAML, or JSON. I prefer to use TOML for my configuration files. If you prefer to use JSON or YAML, you’ll need to translate my examples. You’ll also need to change the name of the file since Hugo uses the extension to determine how to process it.&lt;/p&gt;
&lt;p&gt;Hugo translates Markdown files into HTML. By default, Hugo expects to find Markdown files in your &lt;code&gt;content/&lt;/code&gt; directory and template files in your &lt;code&gt;themes/&lt;/code&gt; directory. It will create HTML files in your &lt;code&gt;public/&lt;/code&gt; directory. You can change this by specifying alternate locations in the configuration file.&lt;/p&gt;
&lt;h3 id=&#34;content&#34;&gt;Content&lt;/h3&gt;
&lt;p&gt;Content is stored in text files that contain two sections. The first section is the “front matter,” which is the meta-information on the content. The second section contains Markdown that will be converted to HTML.&lt;/p&gt;
&lt;h4 id=&#34;front-matter&#34;&gt;Front Matter&lt;/h4&gt;
&lt;p&gt;The front matter is information about the content. Like the configuration file, it can be written in TOML, YAML, or JSON. Unlike the configuration file, Hugo doesn’t use the file’s extension to know the format. It looks for markers to signal the type. TOML is surrounded by “&lt;code&gt;+++&lt;/code&gt;”, YAML by “&lt;code&gt;---&lt;/code&gt;”, and JSON is enclosed in curly braces. I prefer to use TOML, so you’ll need to translate my examples if you prefer YAML or JSON.&lt;/p&gt;
&lt;p&gt;The information in the front matter is passed into the template before the content is rendered into HTML.&lt;/p&gt;
&lt;h4 id=&#34;markdown&#34;&gt;Markdown&lt;/h4&gt;
&lt;p&gt;Content is written in Markdown which makes it easier to create the content. Hugo runs the content through a Markdown engine to create the HTML which will be written to the output file.&lt;/p&gt;
&lt;h3 id=&#34;template-files&#34;&gt;Template Files&lt;/h3&gt;
&lt;p&gt;Hugo uses template files to render content into HTML. Template files are a bridge between the content and presentation. Rules in the template define what content is published, where it&amp;rsquo;s published to, and how it will rendered to the HTML file. The template guides the presentation by specifying the style to use.&lt;/p&gt;
&lt;p&gt;There are three types of templates: single, list, and partial. Each type takes a bit of content as input and transforms it based on the commands in the template.&lt;/p&gt;
&lt;p&gt;Hugo uses its knowledge of the content to find the template file used to render the content. If it can’t find a template that is an exact match for the content, it will shift up a level and search from there. It will continue to do so until it finds a matching template or runs out of templates to try. If it can’t find a template, it will use the default template for the site.&lt;/p&gt;
&lt;p&gt;Please note that you can use the front matter to influence Hugo’s choice of templates.&lt;/p&gt;
&lt;h4 id=&#34;single-template&#34;&gt;Single Template&lt;/h4&gt;
&lt;p&gt;A single template is used to render a single piece of content. For example, an article or post would be a single piece of content and use a single template.&lt;/p&gt;
&lt;h4 id=&#34;list-template&#34;&gt;List Template&lt;/h4&gt;
&lt;p&gt;A list template renders a group of related content. That could be a summary of recent postings or all articles in a category. List templates can contain multiple groups.&lt;/p&gt;
&lt;p&gt;The homepage template is a special type of list template. Hugo assumes that the home page of your site will act as the portal for the rest of the content in the site.&lt;/p&gt;
&lt;h4 id=&#34;partial-template&#34;&gt;Partial Template&lt;/h4&gt;
&lt;p&gt;A partial template is a template that can be included in other templates. Partial templates must be called using the “partial” template command. They are very handy for rolling up common behavior. For example, your site may have a banner that all pages use. Instead of copying the text of the banner into every single and list template, you could create a partial with the banner in it. That way if you decide to change the banner, you only have to change the partial template.&lt;/p&gt;
&lt;h2 id=&#34;create-a-new-site&#34;&gt;Create a New Site&lt;/h2&gt;
&lt;p&gt;Let&amp;rsquo;s use Hugo to create a new web site. I&amp;rsquo;m a Mac user, so I&amp;rsquo;ll create mine in my home directory, in the Sites folder. If you&amp;rsquo;re using Linux, you might have to create the folder first.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;new site&amp;rdquo; command will create a skeleton of a site. It will give you the basic directory structure and a useable configuration file.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ hugo new site ~/Sites/zafta
$ cd ~/Sites/zafta
$ ls -l

&lt;p&gt;Running the &lt;code&gt;hugo&lt;/code&gt; command with no options will read all the available content and generate the HTML files. It will also copy all static files (that&amp;rsquo;s everything that&amp;rsquo;s not content). Since we have an empty site, it won&amp;rsquo;t do much, but it will do it very quickly.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The &amp;ldquo;&lt;code&gt;--verbose&lt;/code&gt;&amp;rdquo; flag gives extra information that will be helpful when we build the template.

The lines that start with &amp;ldquo;WARN:&amp;rdquo; are warning messages. We&amp;rsquo;ll go over them later.&lt;/p&gt;
&lt;p&gt;We can verify that the command worked by looking at the directory again.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;See that new public/ directory? Hugo placed all generated content there. When you&amp;rsquo;re ready to publish your web site, that&amp;rsquo;s the place to start. For now, though, let&amp;rsquo;s just confirm that we have what we&amp;rsquo;d expect from a site with no content.&lt;/p&gt;

&lt;p&gt;Verify that you can run the built-in web server. It will dramatically shorten your development cycle if you do. Start it by running the &amp;ldquo;server&amp;rdquo; command. If it is successful, you will see output similar to the following:&lt;/p&gt;

Web Server is available at http://localhost:1313
Press Ctrl+C to stop
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Connect to the listed URL (it&amp;rsquo;s on the line that starts with &amp;ldquo;Web Server&amp;rdquo;). If everything is working correctly, you should get a page that shows the following:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;index.xml
sitemap.xml
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;That&amp;rsquo;s a listing of your public/ directory. Hugo didn&amp;rsquo;t create a home page because our site has no content. When there&amp;rsquo;s no index.html file in a directory, the server lists the files in the directory, which is what you should see in your browser.&lt;/p&gt;
&lt;p&gt;Let’s go back and look at those warnings again.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;WARN: 2014/09/29 Unable to locate layout: [index.html _default/list.html _default/single.html]
WARN: 2014/09/29 Unable to locate layout: [404.html]
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;That second warning is easier to explain. We haven’t created a template to be used to generate “page not found errors.” The 404 message is a topic for a separate tutorial.&lt;/p&gt;
&lt;p&gt;Now for the first warning. It is for the home page. You can tell because the first layout that it looked for was “index.html.” That’s only used by the home page.&lt;/p&gt;
&lt;p&gt;I like that the verbose flag causes Hugo to list the files that it&amp;rsquo;s searching for. For the home page, they are index.html, _default/list.html, and _default/single.html. There are some rules that we&amp;rsquo;ll cover later that explain the names and paths. For now, just remember that Hugo couldn&amp;rsquo;t find a template for the home page and it told you so.&lt;/p&gt;
&lt;p&gt;At this point, you&amp;rsquo;ve got a working installation and site that we can build upon. All that’s left is to add some content and a theme to display it.&lt;/p&gt;
&lt;h2 id=&#34;create-a-new-theme&#34;&gt;Create a New Theme&lt;/h2&gt;
&lt;p&gt;Hugo doesn&amp;rsquo;t ship with a default theme. There are a few available (I counted a dozen when I first installed Hugo) and Hugo comes with a command to create new themes.&lt;/p&gt;
&lt;p&gt;We&amp;rsquo;re going to create a new theme called &amp;ldquo;zafta.&amp;rdquo; Since the goal of this tutorial is to show you how to fill out the files to pull in your content, the theme will not contain any CSS. In other words, ugly but functional.&lt;/p&gt;
&lt;p&gt;All themes have opinions on content and layout. For example, Zafta uses &amp;ldquo;post&amp;rdquo; over &amp;ldquo;blog&amp;rdquo;. Strong opinions make for simpler templates but differing opinions make it tougher to use themes. When you build a theme, consider using the terms that other themes do.&lt;/p&gt;
&lt;h3 id=&#34;create-a-skeleton&#34;&gt;Create a Skeleton&lt;/h3&gt;
&lt;p&gt;Use the hugo &amp;ldquo;new&amp;rdquo; command to create the skeleton of a theme. This creates the directory structure and places empty files for you to fill out.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ hugo new theme zafta

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The skeleton includes templates (the files ending in .html), license file, a description of your theme (the theme.toml file), and an empty archetype.&lt;/p&gt;
&lt;p&gt;Please take a minute to fill out the theme.toml and LICENSE.md files. They&amp;rsquo;re optional, but if you&amp;rsquo;re going to be distributing your theme, it tells the world who to praise (or blame). It&amp;rsquo;s also nice to declare the license so that people will know how they can use the theme.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Note that the the skeleton&amp;rsquo;s template files are empty. Don&amp;rsquo;t worry, we&amp;rsquo;ll be changing that shortly.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find themes/zafta -name &#39;*.html&#39; | xargs ls -l

$
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;update-the-configuration-file-to-use-the-theme&#34;&gt;Update the Configuration File to Use the Theme&lt;/h3&gt;
&lt;p&gt;Now that we&amp;rsquo;ve got a theme to work with, it&amp;rsquo;s a good idea to add the theme name to the configuration file. This is optional, because you can always add &amp;ldquo;-t zafta&amp;rdquo; on all your commands. I like to put it the configuration file because I like shorter command lines. If you don&amp;rsquo;t put it in the configuration file or specify it on the command line, you won&amp;rsquo;t use the template that you&amp;rsquo;re expecting to.&lt;/p&gt;
&lt;p&gt;Edit the file to add the theme, add a title for the site, and specify that all of our content will use the TOML format.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi config.toml
theme = &amp;quot;zafta&amp;quot;
baseurl = &amp;quot;&amp;quot;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Did you notice that the output is different? The warning message for the home page has disappeared and we have an additional information line saying that Hugo is syncing from the theme&amp;rsquo;s directory.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s check the public/ directory to see what Hugo&amp;rsquo;s created.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ ls -l public

-rw-r--r--  1 quoha  staff  243 Sep 29 17:56 sitemap.xml
$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Notice four things:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Hugo created a home page. This is the file public/index.html.&lt;/li&gt;
&lt;li&gt;Hugo created a css/ directory.&lt;/li&gt;
&lt;li&gt;Hugo created a js/ directory.&lt;/li&gt;
&lt;li&gt;Hugo claimed that it created 0 pages. It created a file and copied over static files, but didn&amp;rsquo;t create any pages. That&amp;rsquo;s because it considers a &amp;ldquo;page&amp;rdquo; to be a file created directly from a content file. It doesn&amp;rsquo;t count things like the index.html files that it creates automatically.&lt;/li&gt;
&lt;/ol&gt;
&lt;h4 id=&#34;the-home-page-1&#34;&gt;The Home Page&lt;/h4&gt;
&lt;p&gt;Hugo supports many different types of templates. The home page is special because it gets its own type of template and its own template file. The file, layouts/index.html, is used to generate the HTML for the home page. The Hugo documentation says that this is the only required template, but that depends. Hugo&amp;rsquo;s warning message shows that it looks for three different templates:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;WARN: 2014/09/29 Unable to locate layout: [index.html _default/list.html _default/single.html]
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;If it can&amp;rsquo;t find any of these, it completely skips creating the home page. We noticed that when we built the site without having a theme installed.&lt;/p&gt;
&lt;p&gt;When Hugo created our theme, it created an empty home page template. Now, when we build the site, Hugo finds the template and uses it to generate the HTML for the home page. Since the template file is empty, the HTML file is empty, too. If the template had any rules in it, then Hugo would have used them to generate the home page.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find . -name index.html | xargs ls -l
-rw-r--r--  1 quoha  staff  0 Sep 29 20:21 ./public/index.html
-rw-r--r--  1 quoha  staff  0 Sep 29 17:31 ./themes/zafta/layouts/index.html
$
&lt;/code&gt;&lt;/pre&gt;&lt;h4 id=&#34;the-magic-of-static&#34;&gt;The Magic of Static&lt;/h4&gt;
&lt;p&gt;Hugo does two things when generating the site. It uses templates to transform content into HTML and it copies static files into the site. Unlike content, static files are not transformed. They are copied exactly as they are.&lt;/p&gt;
&lt;p&gt;Hugo assumes that your site will use both CSS and JavaScript, so it creates directories in your theme to hold them. Remember opinions? Well, Hugo&amp;rsquo;s opinion is that you&amp;rsquo;ll store your CSS in a directory named css/ and your JavaScript in a directory named js/. If you don&amp;rsquo;t like that, you can change the directory names in your theme directory or even delete them completely. Hugo&amp;rsquo;s nice enough to offer its opinion, then behave nicely if you disagree.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;h2 id=&#34;the-theme-development-cycle&#34;&gt;The Theme Development Cycle&lt;/h2&gt;
&lt;p&gt;When you&amp;rsquo;re working on a theme, you will make changes in the theme&amp;rsquo;s directory, rebuild the site, and check your changes in the browser. Hugo makes this very easy:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Purge the public/ directory.&lt;/li&gt;
&lt;li&gt;Run the built in web server in watch mode.&lt;/li&gt;
&lt;li&gt;Open your site in a browser.&lt;/li&gt;
&lt;li&gt;Update the theme.&lt;/li&gt;
&lt;li&gt;Glance at your browser window to see changes.&lt;/li&gt;
&lt;li&gt;Return to step 4.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;I’ll throw in one more opinion: never work on a theme on a live site. Always work on a copy of your site. Make changes to your theme, test them, then copy them up to your site. For added safety, use a tool like Git to keep a revision history of your content and your theme. Believe me when I say that it is too easy to lose both your mind and your changes.&lt;/p&gt;
&lt;p&gt;Check the main Hugo site for information on using Git with Hugo.&lt;/p&gt;
&lt;h3 id=&#34;purge-the-public-directory&#34;&gt;Purge the public/ Directory&lt;/h3&gt;
&lt;p&gt;When generating the site, Hugo will create new files and update existing ones in the &lt;code&gt;public/&lt;/code&gt; directory. It will not delete files that are no longer used. For example, files that were created in the wrong directory or with the wrong title will remain. If you leave them, you might get confused by them later. I recommend cleaning out your site prior to generating it.&lt;/p&gt;
&lt;p&gt;Note: If you&amp;rsquo;re building on an SSD, you should ignore this. Churning on a SSD can be costly.&lt;/p&gt;
&lt;h3 id=&#34;hugos-watch-option&#34;&gt;Hugo&amp;rsquo;s Watch Option&lt;/h3&gt;
&lt;p&gt;Hugo&amp;rsquo;s &amp;ldquo;&lt;code&gt;--watch&lt;/code&gt;&amp;rdquo; option will monitor the content/ and your theme directories for changes and rebuild the site automatically.&lt;/p&gt;
&lt;h3 id=&#34;live-reload&#34;&gt;Live Reload&lt;/h3&gt;
&lt;p&gt;Hugo&amp;rsquo;s built in web server supports live reload. As pages are saved on the server, the browser is told to refresh the page. Usually, this happens faster than you can say, &amp;ldquo;Wow, that&amp;rsquo;s totally amazing.&amp;rdquo;&lt;/p&gt;
&lt;h3 id=&#34;development-commands&#34;&gt;Development Commands&lt;/h3&gt;
&lt;p&gt;Use the following commands as the basis for your workflow.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;## purge old files. hugo will recreate the public directory.
##
$ rm -rf public
##
## run hugo in watch mode
##
$ hugo server --watch --verbose
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Here&amp;rsquo;s sample output showing Hugo detecting a change to the template for the home page. Once generated, the web browser automatically reloaded the page. I&amp;rsquo;ve said this before, it&amp;rsquo;s amazing.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;h2 id=&#34;update-the-home-page-template&#34;&gt;Update the Home Page Template&lt;/h2&gt;
&lt;p&gt;The home page is one of a few special pages that Hugo creates automatically. As mentioned earlier, it looks for one of three files in the theme&amp;rsquo;s layout/ directory:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;index.html&lt;/li&gt;
&lt;li&gt;_default/list.html&lt;/li&gt;
&lt;li&gt;_default/single.html&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;We could update one of the default templates, but a good design decision is to update the most specific template available. That&amp;rsquo;s not a hard and fast rule (in fact, we&amp;rsquo;ll break it a few times in this tutorial), but it is a good generalization.&lt;/p&gt;
&lt;h3 id=&#34;make-a-static-home-page&#34;&gt;Make a Static Home Page&lt;/h3&gt;
&lt;p&gt;Right now, that page is empty because we don&amp;rsquo;t have any content and we don&amp;rsquo;t have any logic in the template. Let&amp;rsquo;s change that by adding some text to the template.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;

&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Build the web site and then verify the results.&lt;/p&gt;

&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;

    + &#39;:1313/livereload.js?mindelay=10&amp;quot;&amp;gt;&amp;lt;/&#39;
        + &#39;script&amp;gt;&#39;)&amp;lt;/script&amp;gt;&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;When you use &lt;code&gt;--watch&lt;/code&gt;, the Live Reload script is added by Hugo. Look for live reload in the documentation to see what it does and how to disable it.&lt;/p&gt;
&lt;h3 id=&#34;build-a-dynamic-home-page&#34;&gt;Build a &amp;ldquo;Dynamic&amp;rdquo; Home Page&lt;/h3&gt;
&lt;p&gt;&amp;ldquo;Dynamic home page?&amp;rdquo; Hugo&amp;rsquo;s a static web site generator, so this seems an odd thing to say. I mean let&amp;rsquo;s have the home page automatically reflect the content in the site every time Hugo builds it. We&amp;rsquo;ll use iteration in the template to do that.&lt;/p&gt;
&lt;h4 id=&#34;create-new-posts&#34;&gt;Create New Posts&lt;/h4&gt;
&lt;p&gt;Now that we have the home page generating static content, let&amp;rsquo;s add some content to the site. We&amp;rsquo;ll display these posts as a list on the home page and on their own page, too.&lt;/p&gt;
&lt;p&gt;Hugo has a command to generate a skeleton post, just like it does for sites and themes.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ hugo --verbose new post/first.md
INFO: 2014/09/29 Using config file: /Users/quoha/Sites/zafta/config.toml

$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;That wasn&amp;rsquo;t very nice, was it?&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;new&amp;rdquo; command uses an archetype to create the post file. Hugo created an empty default archetype file, but that causes an error when there&amp;rsquo;s a theme. For me, the workaround was to create an archetypes file specifically for the post type.&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The output says that it created 2 pages. Those are our new posts:&lt;/p&gt;

$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The new files are empty because because the templates used to generate the content are empty. The homepage doesn&amp;rsquo;t show the new content, either. We have to update the templates to add the posts.&lt;/p&gt;
&lt;h3 id=&#34;list-and-single-templates&#34;&gt;List and Single Templates&lt;/h3&gt;
&lt;p&gt;In Hugo, we have three major kinds of templates. There&amp;rsquo;s the home page template that we updated previously. It is used only by the home page. We also have &amp;ldquo;single&amp;rdquo; templates which are used to generate output for a single content file. We also have &amp;ldquo;list&amp;rdquo; templates that are used to group multiple pieces of content before generating output.&lt;/p&gt;
&lt;p&gt;Generally speaking, list templates are named &amp;ldquo;list.html&amp;rdquo; and single templates are named &amp;ldquo;single.html.&amp;rdquo;&lt;/p&gt;
&lt;p&gt;There are three other types of templates: partials, content views, and terms. We will not go into much detail on these.&lt;/p&gt;
&lt;h3 id=&#34;add-content-to-the-homepage&#34;&gt;Add Content to the Homepage&lt;/h3&gt;
&lt;p&gt;The home page will contain a list of posts. Let&amp;rsquo;s update its template to add the posts that we just created. The logic in the template will run every time we build the site.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
  {{ range first 10 .Data.Pages }}
    &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  {{ end }}
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
:wq

$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Hugo uses the Go template engine. That engine scans the template files for commands which are enclosed between &amp;ldquo;{{&amp;rdquo; and &amp;ldquo;}}&amp;quot;. In our template, the commands are:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;range&lt;/li&gt;
&lt;li&gt;.Title&lt;/li&gt;
&lt;li&gt;end&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;The &amp;ldquo;range&amp;rdquo; command is an iterator. We&amp;rsquo;re going to use it to go through the first ten pages. Every HTML file that Hugo creates is treated as a page, so looping through the list of pages will look at every file that will be created.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;.Title&amp;rdquo; command prints the value of the &amp;ldquo;title&amp;rdquo; variable. Hugo pulls it from the front matter in the Markdown file.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;end&amp;rdquo; command signals the end of the range iterator. The engine loops back to the top of the iteration when it finds &amp;ldquo;end.&amp;rdquo; Everything between the &amp;ldquo;range&amp;rdquo; and &amp;ldquo;end&amp;rdquo; is evaluated every time the engine goes through the iteration. In this file, that would cause the title from the first ten pages to be output as heading level one.&lt;/p&gt;
&lt;p&gt;It&amp;rsquo;s helpful to remember that some variables, like .Data, are created before any output files. Hugo loads every content file into the variable and then gives the template a chance to process before creating the HTML files.&lt;/p&gt;
&lt;p&gt;Build the web site and then verify the results.&lt;/p&gt;

    &amp;lt;h1&amp;gt;first&amp;lt;/h1&amp;gt;

&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
$
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Congratulations, the home page shows the title of the two posts. The posts themselves are still empty, but let&amp;rsquo;s take a moment to appreciate what we&amp;rsquo;ve done. Your template now generates output dynamically. Believe it or not, by inserting the range command inside of those curly braces, you&amp;rsquo;ve learned everything you need to know to build a theme. All that&amp;rsquo;s really left is understanding which template will be used to generate each content file and becoming familiar with the commands for the template engine.&lt;/p&gt;
&lt;p&gt;And, if that were entirely true, this tutorial would be much shorter. There are a few things to know that will make creating a new template much easier. Don&amp;rsquo;t worry, though, that&amp;rsquo;s all to come.&lt;/p&gt;
&lt;h3 id=&#34;add-content-to-the-posts&#34;&gt;Add Content to the Posts&lt;/h3&gt;
&lt;p&gt;We&amp;rsquo;re working with posts, which are in the content/post/ directory. That means that their section is &amp;ldquo;post&amp;rdquo; (and if we don&amp;rsquo;t do something weird, their type is also &amp;ldquo;post&amp;rdquo;).&lt;/p&gt;
&lt;p&gt;Hugo uses the section and type to find the template file for every piece of content. Hugo will first look for a template file that matches the section or type name. If it can&amp;rsquo;t find one, then it will look in the _default/ directory. There are some twists that we&amp;rsquo;ll cover when we get to categories and tags, but for now we can assume that Hugo will try post/single.html, then _default/single.html.&lt;/p&gt;
&lt;p&gt;Now that we know the search rule, let&amp;rsquo;s see what we actually have available:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find themes/zafta -name single.html | xargs ls -l
-rw-r--r--  1 quoha  staff  132 Sep 29 17:31 themes/zafta/layouts/_default/single.html
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;We could create a new template, post/single.html, or change the default. Since we don&amp;rsquo;t know of any other content types, let&amp;rsquo;s start with updating the default.&lt;/p&gt;
&lt;p&gt;Remember, any content that we haven&amp;rsquo;t created a template for will end up using this template. That can be good or bad. Bad because I know that we&amp;rsquo;re going to be adding different types of content and we&amp;rsquo;re going to end up undoing some of the changes we&amp;rsquo;ve made. It&amp;rsquo;s good because we&amp;rsquo;ll be able to see immediate results. It&amp;rsquo;s also good to start here because we can start to build the basic layout for the site. As we add more content types, we&amp;rsquo;ll refactor this file and move logic around. Hugo makes that fairly painless, so we&amp;rsquo;ll accept the cost and proceed.&lt;/p&gt;
&lt;p&gt;Please see the Hugo documentation on template rendering for all the details on determining which template to use. And, as the docs mention, if you&amp;rsquo;re building a single page application (SPA) web site, you can delete all of the other templates and work with just the default single page. That&amp;rsquo;s a refreshing amount of joy right there.&lt;/p&gt;
&lt;h4 id=&#34;update-the-template-file&#34;&gt;Update the Template File&lt;/h4&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/_default/single.html

$
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;create-a-post-listing&#34;&gt;Create a Post Listing&lt;/h3&gt;
&lt;p&gt;We have the posts displaying on the home page and on their own page. We also have a file public/post/index.html that is empty. Let&amp;rsquo;s make it show a list of all posts (not just the first ten).&lt;/p&gt;
&lt;p&gt;We need to decide which template to update. This will be a listing, so it should be a list template. Let&amp;rsquo;s take a quick look and see which list templates are available.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find themes/zafta -name list.html | xargs ls -l
-rw-r--r--  1 quoha  staff  0 Sep 29 17:31 themes/zafta/layouts/_default/list.html
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;As with the single post, we have to decide to update _default/list.html or create post/list.html. We still don&amp;rsquo;t have multiple content types, so let&amp;rsquo;s stay consistent and update the default list template.&lt;/p&gt;
&lt;h2 id=&#34;creating-top-level-pages&#34;&gt;Creating Top Level Pages&lt;/h2&gt;
&lt;p&gt;Let&amp;rsquo;s add an &amp;ldquo;about&amp;rdquo; page and display it at the top level (as opposed to a sub-level like we did with posts).&lt;/p&gt;
&lt;p&gt;The default in Hugo is to use the directory structure of the content/ directory to guide the location of the generated html in the public/ directory. Let&amp;rsquo;s verify that by creating an &amp;ldquo;about&amp;rdquo; page at the top level:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi content/about.md
+++
title = &amp;quot;about&amp;quot;
description = &amp;quot;about this site&amp;quot;
date = &amp;quot;2014-09-27&amp;quot;
slug = &amp;quot;about time&amp;quot;
+++

## about us

i&#39;m speechless
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find public -name &#39;*.html&#39; | xargs ls -l
-rw-rw-r--  1 mdhender  staff   334 Sep 27 15:08 public/about-time/index.html

-rw-rw-r--  1 mdhender  staff   342 Sep 27 15:08 public/post/second-post/index.html
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Notice that the page wasn&amp;rsquo;t created at the top level. It was created in a sub-directory named &amp;lsquo;about-time/&#39;. That name came from our slug. Hugo will use the slug to name the generated content. It&amp;rsquo;s a reasonable default, by the way, but we can learn a few things by fighting it for this file.&lt;/p&gt;
&lt;p&gt;One other thing. Take a look at the home page.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ cat public/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/post/theme/&amp;quot;&amp;gt;creating a new theme&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/about-time/&amp;quot;&amp;gt;about&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/post/second-post/&amp;quot;&amp;gt;second&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
    &amp;lt;h1&amp;gt;&amp;lt;a href=&amp;quot;http://localhost:1313/post/first-post/&amp;quot;&amp;gt;first&amp;lt;/a&amp;gt;&amp;lt;/h1&amp;gt;
&amp;lt;script&amp;gt;document.write(&#39;&amp;lt;script src=&amp;quot;http://&#39;
        + (location.host || &#39;localhost&#39;).split(&#39;:&#39;)[0]
		+ &#39;:1313/livereload.js?mindelay=10&amp;quot;&amp;gt;&amp;lt;/&#39;
        + &#39;script&amp;gt;&#39;)&amp;lt;/script&amp;gt;&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Notice that the &amp;ldquo;about&amp;rdquo; link is listed with the posts? That&amp;rsquo;s not desirable, so let&amp;rsquo;s change that first.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;body&amp;gt;
  &amp;lt;h1&amp;gt;posts&amp;lt;/h1&amp;gt;
  {{ range first 10 .Data.Pages }}
    {{ if eq .Type &amp;quot;post&amp;quot;}}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Title }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}

  &amp;lt;h1&amp;gt;pages&amp;lt;/h1&amp;gt;
  {{ range .Data.Pages }}
    {{ if eq .Type &amp;quot;page&amp;quot; }}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Title }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The home page has two sections, posts and pages, and each section has the right set of headings and links in it.&lt;/p&gt;
&lt;p&gt;But, that about page still renders to about-time/index.html.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ find public -name &#39;*.html&#39; | xargs ls -l
-rw-rw-r--  1 mdhender  staff    334 Sep 27 15:33 public/about-time/index.html
-rw-rw-r--  1 mdhender  staff    645 Sep 27 15:33 public/index.html

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Knowing that hugo is using the slug to generate the file name, the simplest solution is to change the slug. Let&amp;rsquo;s do it the hard way and change the permalink in the configuration file.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi config.toml
[permalinks]
	page = &amp;quot;/:title/&amp;quot;
	about = &amp;quot;/:filename/&amp;quot;
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify that this didn&amp;rsquo;t work. Hugo lets &amp;ldquo;slug&amp;rdquo; or &amp;ldquo;URL&amp;rdquo; override the permalinks setting in the configuration file. Go ahead and comment out the slug in content/about.md, then generate the web site to get it to be created in the right place.&lt;/p&gt;
&lt;h2 id=&#34;sharing-templates&#34;&gt;Sharing Templates&lt;/h2&gt;
&lt;p&gt;If you&amp;rsquo;ve been following along, you probably noticed that posts have titles in the browser and the home page doesn&amp;rsquo;t. That&amp;rsquo;s because we didn&amp;rsquo;t put the title in the home page&amp;rsquo;s template (layouts/index.html). That&amp;rsquo;s an easy thing to do, but let&amp;rsquo;s look at a different option.&lt;/p&gt;
&lt;p&gt;We can put the common bits into a shared template that&amp;rsquo;s stored in the themes/zafta/layouts/partials/ directory.&lt;/p&gt;
&lt;h3 id=&#34;create-the-header-and-footer-partials&#34;&gt;Create the Header and Footer Partials&lt;/h3&gt;
&lt;p&gt;In Hugo, a partial is a sugar-coated template. Normally a template reference has a path specified. Partials are different. Hugo searches for them along a TODO defined search path. This makes it easier for end-users to override the theme&amp;rsquo;s presentation.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/partials/header.html
&amp;lt;!DOCTYPE html&amp;gt;
&amp;lt;html&amp;gt;
&amp;lt;head&amp;gt;
	&amp;lt;title&amp;gt;{{ .Title }}&amp;lt;/title&amp;gt;
&amp;lt;/head&amp;gt;
&amp;lt;body&amp;gt;
:wq

$ vi themes/zafta/layouts/partials/footer.html
&amp;lt;/body&amp;gt;
&amp;lt;/html&amp;gt;
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;h3 id=&#34;update-the-home-page-template-to-use-the-partials&#34;&gt;Update the Home Page Template to Use the Partials&lt;/h3&gt;
&lt;p&gt;The most noticeable difference between a template call and a partials call is the lack of path:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ template &amp;quot;theme/partials/header.html&amp;quot; . }}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;versus&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ partial &amp;quot;header.html&amp;quot; . }}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Both pass in the context.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s change the home page template to use these new partials.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/index.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;posts&amp;lt;/h1&amp;gt;
  {{ range first 10 .Data.Pages }}
    {{ if eq .Type &amp;quot;post&amp;quot;}}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Title }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}

  &amp;lt;h1&amp;gt;pages&amp;lt;/h1&amp;gt;
  {{ range .Data.Pages }}
    {{ if or (eq .Type &amp;quot;page&amp;quot;) (eq .Type &amp;quot;about&amp;quot;) }}
      &amp;lt;h2&amp;gt;&amp;lt;a href=&amp;quot;{{ .Permalink }}&amp;quot;&amp;gt;{{ .Type }} - {{ .Title }} - {{ .RelPermalink }}&amp;lt;/a&amp;gt;&amp;lt;/h2&amp;gt;
    {{ end }}
  {{ end }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The title on the home page is now &amp;ldquo;your title here&amp;rdquo;, which comes from the &amp;ldquo;title&amp;rdquo; variable in the config.toml file.&lt;/p&gt;
&lt;h3 id=&#34;update-the-default-single-template-to-use-the-partials&#34;&gt;Update the Default Single Template to Use the Partials&lt;/h3&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/_default/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The title on the posts and the about page should both reflect the value in the markdown file.&lt;/p&gt;
&lt;h2 id=&#34;add-date-published-to-posts&#34;&gt;Add “Date Published” to Posts&lt;/h2&gt;
&lt;p&gt;It&amp;rsquo;s common to have posts display the date that they were written or published, so let&amp;rsquo;s add that. The front matter of our posts has a variable named &amp;ldquo;date.&amp;rdquo; It&amp;rsquo;s usually the date the content was created, but let&amp;rsquo;s pretend that&amp;rsquo;s the value we want to display.&lt;/p&gt;
&lt;h3 id=&#34;add-date-published-to-the-template&#34;&gt;Add “Date Published” to the Template&lt;/h3&gt;
&lt;p&gt;We&amp;rsquo;ll start by updating the template used to render the posts. The template code will look like:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ .Date.Format &amp;quot;Mon, Jan 2, 2006&amp;quot; }}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Posts use the default single template, so we&amp;rsquo;ll change that file.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/_default/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  &amp;lt;h2&amp;gt;{{ .Date.Format &amp;quot;Mon, Jan 2, 2006&amp;quot; }}&amp;lt;/h2&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Generate the web site and verify the results. The posts now have the date displayed in them. There&amp;rsquo;s a problem, though. The &amp;ldquo;about&amp;rdquo; page also has the date displayed.&lt;/p&gt;
&lt;p&gt;As usual, there are a couple of ways to make the date display only on posts. We could do an &amp;ldquo;if&amp;rdquo; statement like we did on the home page. Another way would be to create a separate template for posts.&lt;/p&gt;
&lt;p&gt;The &amp;ldquo;if&amp;rdquo; solution works for sites that have just a couple of content types. It aligns with the principle of &amp;ldquo;code for today,&amp;rdquo; too.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s assume, though, that we&amp;rsquo;ve made our site so complex that we feel we have to create a new template type. In Hugo-speak, we&amp;rsquo;re going to create a section template.&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s restore the default single template before we forget.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ mkdir themes/zafta/layouts/post
$ vi themes/zafta/layouts/_default/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Now we&amp;rsquo;ll update the post&amp;rsquo;s version of the single template. If you remember Hugo&amp;rsquo;s rules, the template engine will use this version over the default.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;$ vi themes/zafta/layouts/post/single.html
{{ partial &amp;quot;header.html&amp;quot; . }}

  &amp;lt;h1&amp;gt;{{ .Title }}&amp;lt;/h1&amp;gt;
  &amp;lt;h2&amp;gt;{{ .Date.Format &amp;quot;Mon, Jan 2, 2006&amp;quot; }}&amp;lt;/h2&amp;gt;
  {{ .Content }}

{{ partial &amp;quot;footer.html&amp;quot; . }}
:wq

&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Note that we removed the date logic from the default template and put it in the post template. Generate the web site and verify the results. Posts have dates and the about page doesn&amp;rsquo;t.&lt;/p&gt;
&lt;h3 id=&#34;dont-repeat-yourself&#34;&gt;Don&amp;rsquo;t Repeat Yourself&lt;/h3&gt;
&lt;p&gt;DRY is a good design goal and Hugo does a great job supporting it. Part of the art of a good template is knowing when to add a new template and when to update an existing one. While you&amp;rsquo;re figuring that out, accept that you&amp;rsquo;ll be doing some refactoring. Hugo makes that easy and fast, so it&amp;rsquo;s okay to delay splitting up a template.&lt;/p&gt;

      <title>(Hu)go Template Primer</title>
      <link>http://www.itspedia.com/post/goisforlovers/</link>
      <pubDate>Wed, 02 Apr 2014 00:00:00 +0000</pubDate>
      
      <guid>http://www.itspedia.com/post/goisforlovers/</guid>
      
        <description>&lt;p&gt;Hugo uses the excellent &lt;a href=&#34;http://golang.org/&#34;&gt;go&lt;/a&gt; &lt;a href=&#34;http://golang.org/pkg/html/template/&#34;&gt;html/template&lt;/a&gt; library for
its template engine. It is an extremely lightweight engine that provides a very
small amount of logic. In our experience that it is just the right amount of
logic to be able to create a good static website. If you have used other
template systems from different languages or frameworks you will find a lot of
similarities in go templates.&lt;/p&gt;
&lt;p&gt;This document is a brief primer on using go templates. The &lt;a href=&#34;http://golang.org/pkg/html/template/&#34;&gt;go docs&lt;/a&gt;
provide more details.&lt;/p&gt;
&lt;h2 id=&#34;introduction-to-go-templates&#34;&gt;Introduction to Go Templates&lt;/h2&gt;
&lt;p&gt;Go templates provide an extremely simple template language. It adheres to the
belief that only the most basic of logic belongs in the template or view layer.
One consequence of this simplicity is that go templates parse very quickly.&lt;/p&gt;
&lt;p&gt;A unique characteristic of go templates is they are content aware. Variables and
content will be sanitized depending on the context of where they are used. More
details can be found in the &lt;a href=&#34;http://golang.org/pkg/html/template/&#34;&gt;go docs&lt;/a&gt;.&lt;/p&gt;
&lt;h2 id=&#34;basic-syntax&#34;&gt;Basic Syntax&lt;/h2&gt;
&lt;p&gt;Go lang templates are html files with the addition of variables and
functions.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Go variables and functions are accessible within {{ }}&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Accessing a predefined variable &amp;ldquo;foo&amp;rdquo;:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ foo }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Parameters are separated using spaces&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Calling the add function with input of 1, 2:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ add 1 2 }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Methods and fields are accessed via dot notation&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Accessing the Page Parameter &amp;ldquo;bar&amp;rdquo;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ .Params.bar }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Parentheses can be used to group items together&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ if or (isset .Params &amp;quot;alt&amp;quot;) (isset .Params &amp;quot;caption&amp;quot;) }} Caption {{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h2 id=&#34;variables&#34;&gt;Variables&lt;/h2&gt;
&lt;p&gt;Each go template has a struct (object) made available to it. In hugo each
template is passed either a page or a node struct depending on which type of
page you are rendering. More details are available on the
&lt;a href=&#34;http://www.itspedia.com/layout/variables&#34;&gt;variables&lt;/a&gt; page.&lt;/p&gt;
&lt;p&gt;A variable is accessed by referencing the variable name.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;&amp;lt;title&amp;gt;{{ .Title }}&amp;lt;/title&amp;gt;
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Variables can also be defined and referenced.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ $address := &amp;quot;123 Main St.&amp;quot;}}
{{ $address }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h2 id=&#34;functions&#34;&gt;Functions&lt;/h2&gt;
&lt;p&gt;Go template ship with a few functions which provide basic functionality. The go
template system also provides a mechanism for applications to extend the
available functions with their own. &lt;a href=&#34;http://www.itspedia.com/layout/functions&#34;&gt;Hugo template
functions&lt;/a&gt; provide some additional functionality we believe
are useful for building websites. Functions are called by using their name
followed by the required parameters separated by spaces. Template
functions cannot be added without recompiling hugo.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Example:&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ add 1 2 }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h2 id=&#34;includes&#34;&gt;Includes&lt;/h2&gt;
&lt;p&gt;When including another template you will pass to it the data it will be
able to access. To pass along the current context please remember to
include a trailing dot. The templates location will always be starting at
the /layout/ directory within Hugo.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Example:&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ template &amp;quot;chrome/header.html&amp;quot; . }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h2 id=&#34;logic&#34;&gt;Logic&lt;/h2&gt;
&lt;p&gt;Go templates provide the most basic iteration and conditional logic.&lt;/p&gt;
&lt;h3 id=&#34;iteration&#34;&gt;Iteration&lt;/h3&gt;
&lt;p&gt;Just like in go, the go templates make heavy use of range to iterate over
a map, array or slice. The following are different examples of how to use
range.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Example 1: Using Context&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ range array }}
    {{ . }}
{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Example 2: Declaring value variable name&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{range $element := array}}
    {{ $element }}
{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Example 2: Declaring key and value variable name&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{range $index, $element := array}}
    {{ $index }}
    {{ $element }}
{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h3 id=&#34;conditionals&#34;&gt;Conditionals&lt;/h3&gt;
&lt;p&gt;If, else, with, or, &amp;amp; and provide the framework for handling conditional
logic in Go Templates. Like range, each statement is closed with &lt;code&gt;end&lt;/code&gt;.&lt;/p&gt;
&lt;p&gt;Go Templates treat the following values as false:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;false&lt;/li&gt;
&lt;li&gt;0&lt;/li&gt;
&lt;li&gt;any array, slice, map, or string of length zero&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;strong&gt;Example 1: If&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ if isset .Params &amp;quot;title&amp;quot; }}&amp;lt;h4&amp;gt;{{ index .Params &amp;quot;title&amp;quot; }}&amp;lt;/h4&amp;gt;{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Example 2: If -&amp;gt; Else&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ if isset .Params &amp;quot;alt&amp;quot; }}
    {{ index .Params &amp;quot;alt&amp;quot; }}
{{else}}
    {{ index .Params &amp;quot;caption&amp;quot; }}
{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Example 3: And &amp;amp; Or&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ if and (or (isset .Params &amp;quot;title&amp;quot;) (isset .Params &amp;quot;caption&amp;quot;)) (isset .Params &amp;quot;attr&amp;quot;)}}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Example 4: With&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;An alternative way of writing &amp;ldquo;if&amp;rdquo; and then referencing the same value
is to use &amp;ldquo;with&amp;rdquo; instead. With rebinds the context &lt;code&gt;.&lt;/code&gt; within its scope,
and skips the block if the variable is absent.&lt;/p&gt;
&lt;p&gt;The first example above could be simplified as:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ with .Params.title }}&amp;lt;h4&amp;gt;{{ . }}&amp;lt;/h4&amp;gt;{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&lt;strong&gt;Example 5: If -&amp;gt; Else If&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ if isset .Params &amp;quot;alt&amp;quot; }}
    {{ index .Params &amp;quot;alt&amp;quot; }}
{{ else if isset .Params &amp;quot;caption&amp;quot; }}
    {{ index .Params &amp;quot;caption&amp;quot; }}
{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h2 id=&#34;pipes&#34;&gt;Pipes&lt;/h2&gt;
&lt;p&gt;One of the most powerful components of go templates is the ability to
stack actions one after another. This is done by using pipes. Borrowed
from unix pipes, the concept is simple, each pipeline&amp;rsquo;s output becomes the
input of the following pipe.&lt;/p&gt;
&lt;p&gt;Because of the very simple syntax of go templates, the pipe is essential
to being able to chain together function calls. One limitation of the
pipes is that they only can work with a single value and that value
becomes the last parameter of the next pipeline.&lt;/p&gt;
&lt;p&gt;A few simple examples should help convey how to use the pipe.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Example 1 :&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ if eq 1 1 }} Same {{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;is the same as&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ eq 1 1 | if }} Same {{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;It does look odd to place the if at the end, but it does provide a good
illustration of how to use the pipes.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Example 2 :&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ index .Params &amp;quot;disqus_url&amp;quot; | html }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Access the page parameter called &amp;ldquo;disqus_url&amp;rdquo; and escape the HTML.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Example 3 :&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{ if or (or (isset .Params &amp;quot;title&amp;quot;) (isset .Params &amp;quot;caption&amp;quot;)) (isset .Params &amp;quot;attr&amp;quot;)}}
Stuff Here
{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Could be rewritten as&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{  isset .Params &amp;quot;caption&amp;quot; | or isset .Params &amp;quot;title&amp;quot; | or isset .Params &amp;quot;attr&amp;quot; | if }}
Stuff Here
{{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h2 id=&#34;context-aka-the-dot&#34;&gt;Context (aka. the dot)&lt;/h2&gt;
&lt;p&gt;The most easily overlooked concept to understand about go templates is that {{ . }}
always refers to the current context. In the top level of your template this
will be the data set made available to it. Inside of a iteration it will have
the value of the current item. When inside of a loop the context has changed. .
will no longer refer to the data available to the entire page. If you need to
access this from within the loop you will likely want to set it to a variable
instead of depending on the context.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Example:&lt;/strong&gt;&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;  {{ $title := .Site.Title }}
  {{ range .Params.tags }}
    &amp;lt;li&amp;gt; &amp;lt;a href=&amp;quot;{{ $baseurl }}/tags/{{ . | urlize }}&amp;quot;&amp;gt;{{ . }}&amp;lt;/a&amp;gt; - {{ $title }} &amp;lt;/li&amp;gt;
  {{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Notice how once we have entered the loop the value of {{ . }} has changed. We
have defined a variable outside of the loop so we have access to it from within
the loop.&lt;/p&gt;
&lt;h1 id=&#34;hugo-parameters&#34;&gt;Hugo Parameters&lt;/h1&gt;
&lt;p&gt;Hugo provides the option of passing values to the template language
through the site configuration (for sitewide values), or through the meta
data of each specific piece of content. You can define any values of any
type (supported by your front matter/config format) and use them however
you want to inside of your templates.&lt;/p&gt;
&lt;h2 id=&#34;using-content-page-parameters&#34;&gt;Using Content (page) Parameters&lt;/h2&gt;
&lt;p&gt;In each piece of content you can provide variables to be used by the
templates. This happens in the &lt;a href=&#34;http://www.itspedia.com/content/front-matter&#34;&gt;front matter&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;An example of this is used in this documentation site. Most of the pages
benefit from having the table of contents provided. Sometimes the TOC just
doesn&amp;rsquo;t make a lot of sense. We&amp;rsquo;ve defined a variable in our front matter
of some pages to turn off the TOC from being displayed.&lt;/p&gt;
&lt;p&gt;Here is the example front matter:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;---
title: &amp;quot;Permalinks&amp;quot;
date: &amp;quot;2013-11-18&amp;quot;
aliases:
  - &amp;quot;/doc/permalinks/&amp;quot;
groups: [&amp;quot;extras&amp;quot;]
groups_weight: 30
notoc: true
---
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Here is the corresponding code inside of the template:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;  {{ if not .Params.notoc }}
    &amp;lt;div id=&amp;quot;toc&amp;quot; class=&amp;quot;well col-md-4 col-sm-6&amp;quot;&amp;gt;
    {{ .TableOfContents }}
    &amp;lt;/div&amp;gt;
  {{ end }}
&lt;/code&gt;&lt;/pre&gt;
&lt;h2 id=&#34;using-site-config-parameters&#34;&gt;Using Site (config) Parameters&lt;/h2&gt;
&lt;p&gt;In your top-level configuration file (eg, &lt;code&gt;config.yaml&lt;/code&gt;) you can define site
parameters, which are values which will be available to you in chrome.&lt;/p&gt;
&lt;p&gt;For instance, you might declare:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-yaml&#34; data-lang=&#34;yaml&#34;&gt;&lt;span style=&#34;color:#66d9ef&#34;&gt;params&lt;/span&gt;:
  &lt;span style=&#34;color:#66d9ef&#34;&gt;CopyrightHTML&lt;/span&gt;: &lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Copyright &amp;amp;#xA9; 2013 John Doe. All Rights Reserved.&amp;#34;&lt;/span&gt;
  &lt;span style=&#34;color:#66d9ef&#34;&gt;TwitterUser&lt;/span&gt;: &lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;spf13&amp;#34;&lt;/span&gt;
  &lt;span style=&#34;color:#66d9ef&#34;&gt;SidebarRecentLimit&lt;/span&gt;: &lt;span style=&#34;color:#ae81ff&#34;&gt;5&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;Within a footer layout, you might then declare a &lt;code&gt;&amp;lt;footer&amp;gt;&lt;/code&gt; which is only
provided if the &lt;code&gt;CopyrightHTML&lt;/code&gt; parameter is provided, and if it is given,
you would declare it to be HTML-safe, so that the HTML entity is not escaped
again.  This would let you easily update just your top-level config file each
January 1st, instead of hunting through your templates.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{if .Site.Params.CopyrightHTML}}&amp;lt;footer&amp;gt;
&amp;lt;div class=&amp;quot;text-center&amp;quot;&amp;gt;{{.Site.Params.CopyrightHTML | safeHtml}}&amp;lt;/div&amp;gt;
&amp;lt;/footer&amp;gt;{{end}}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;An alternative way of writing the &amp;ldquo;if&amp;rdquo; and then referencing the same value
is to use &amp;ldquo;with&amp;rdquo; instead. With rebinds the context &lt;code&gt;.&lt;/code&gt; within its scope,
and skips the block if the variable is absent:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{with .Site.Params.TwitterUser}}&amp;lt;span class=&amp;quot;twitter&amp;quot;&amp;gt;
&amp;lt;a href=&amp;quot;https://twitter.com/{{.}}&amp;quot; rel=&amp;quot;author&amp;quot;&amp;gt;
&amp;lt;img src=&amp;quot;/images/twitter.png&amp;quot; width=&amp;quot;48&amp;quot; height=&amp;quot;48&amp;quot; title=&amp;quot;Twitter: {{.}}&amp;quot;
 alt=&amp;quot;Twitter&amp;quot;&amp;gt;&amp;lt;/a&amp;gt;
&amp;lt;/span&amp;gt;{{end}}
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;Finally, if you want to pull &amp;ldquo;magic constants&amp;rdquo; out of your layouts, you can do
so, such as in this example:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;&amp;lt;nav class=&amp;quot;recent&amp;quot;&amp;gt;
  &amp;lt;h1&amp;gt;Recent Posts&amp;lt;/h1&amp;gt;
  &amp;lt;ul&amp;gt;{{range first .Site.Params.SidebarRecentLimit .Site.Recent}}
    &amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;{{.RelPermalink}}&amp;quot;&amp;gt;{{.Title}}&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;
  {{end}}&amp;lt;/ul&amp;gt;
&amp;lt;/nav&amp;gt;
&lt;/code&gt;&lt;/pre&gt;</description>

      <title>Getting Started with Hugo</title>
      <link>http://www.itspedia.com/post/hugoisforlovers/</link>
      <pubDate>Wed, 02 Apr 2014 00:00:00 +0000</pubDate>
      
      <guid>http://www.itspedia.com/post/hugoisforlovers/</guid>
      
        <description>&lt;h2 id=&#34;step-1-install-hugo&#34;&gt;Step 1. Install Hugo&lt;/h2&gt;
&lt;p&gt;Goto &lt;a href=&#34;https://github.com/spf13/hugo/releases&#34;&gt;hugo releases&lt;/a&gt; and download the
appropriate version for your os and architecture.&lt;/p&gt;
&lt;p&gt;Save it somewhere specific as we will be using it in the next step.&lt;/p&gt;
&lt;p&gt;More complete instructions are available at &lt;a href=&#34;http://www.itspedia.com/overview/installing/&#34;&gt;installing hugo&lt;/a&gt;&lt;/p&gt;
&lt;h2 id=&#34;step-2-build-the-docs&#34;&gt;Step 2. Build the Docs&lt;/h2&gt;
&lt;p&gt;Hugo has its own example site which happens to also be the documentation site
you are reading right now.&lt;/p&gt;
&lt;p&gt;Follow the following steps:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Clone the &lt;a href=&#34;http://github.com/spf13/hugo&#34;&gt;hugo repository&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Go into the repo&lt;/li&gt;
&lt;li&gt;Run hugo in server mode and build the docs&lt;/li&gt;
&lt;li&gt;Open your browser to http://localhost:1313&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;Corresponding pseudo commands:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;git clone https://github.com/spf13/hugo
cd hugo
/path/to/where/you/installed/hugo server --source=./docs
&amp;gt; 29 pages created
&amp;gt; 0 tags index created
&amp;gt; in 27 ms
&amp;gt; Web Server is available at http://localhost:1313
&amp;gt; Press ctrl+c to stop
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Once you&amp;rsquo;ve gotten here, follow along the rest of this page on your local build.&lt;/p&gt;
&lt;h2 id=&#34;step-3-change-the-docs-site&#34;&gt;Step 3. Change the docs site&lt;/h2&gt;
&lt;p&gt;Stop the Hugo process by hitting ctrl+c.&lt;/p&gt;
&lt;p&gt;Now we are going to run hugo again, but this time with hugo in watch mode.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;/path/to/hugo/from/step/1/hugo server --source=./docs --watch
&amp;gt; 29 pages created
&amp;gt; 0 tags index created
&amp;gt; in 27 ms
&amp;gt; Web Server is available at http://localhost:1313
&amp;gt; Watching for changes in /Users/spf13/Code/hugo/docs/content
&amp;gt; Press ctrl+c to stop
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Open your &lt;a href=&#34;http://vim.spf13.com&#34;&gt;favorite editor&lt;/a&gt; and change one of the source
content pages. How about changing this very file to &lt;em&gt;fix the typo&lt;/em&gt;. How about changing this very file to &lt;em&gt;fix the typo&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Content files are found in &lt;code&gt;docs/content/&lt;/code&gt;. Unless otherwise specified, files
are located at the same relative location as the url, in our case
&lt;code&gt;docs/content/overview/quickstart.md&lt;/code&gt;.&lt;/p&gt;
&lt;p&gt;Change and save this file.. Notice what happened in your terminal.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;&amp;gt; Change detected, rebuilding site

&amp;gt; 29 pages created
&amp;gt; 0 tags index created
&amp;gt; in 26 ms
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Refresh the browser and observe that the typo is now fixed.&lt;/p&gt;
&lt;p&gt;Notice how quick that was. Try to refresh the site before it&amp;rsquo;s finished building.. I double dare you.
Having nearly instant feedback enables you to have your creativity flow without waiting for long builds.&lt;/p&gt;
&lt;h2 id=&#34;step-4-have-fun&#34;&gt;Step 4. Have fun&lt;/h2&gt;
&lt;p&gt;The best way to learn something is to play with it.&lt;/p&gt;

      <title>Migrate to Hugo from Jekyll</title>
      <link>http://www.itspedia.com/post/migrate-from-jekyll/</link>
      <pubDate>Mon, 10 Mar 2014 00:00:00 +0000</pubDate>
      
      <guid>http://www.itspedia.com/post/migrate-from-jekyll/</guid>
      
        <description>&lt;h2 id=&#34;move-static-content-to-static&#34;&gt;Move static content to &lt;code&gt;static&lt;/code&gt;&lt;/h2&gt;
&lt;p&gt;Jekyll has a rule that any directory not starting with &lt;code&gt;_&lt;/code&gt; will be copied as-is to the &lt;code&gt;_site&lt;/code&gt; output. Hugo keeps all static content under &lt;code&gt;static&lt;/code&gt;. You should therefore move it all there.
With Jekyll, something that looked like&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;▾ &amp;lt;root&amp;gt;/
    ▾ images/
        logo.png
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;should become&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;▾ &amp;lt;root&amp;gt;/
    ▾ static/
        ▾ images/
            logo.png
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Additionally, you&amp;rsquo;ll want any files that should reside at the root (such as &lt;code&gt;CNAME&lt;/code&gt;) to be moved to &lt;code&gt;static&lt;/code&gt;.&lt;/p&gt;
&lt;h2 id=&#34;create-your-hugo-configuration-file&#34;&gt;Create your Hugo configuration file&lt;/h2&gt;
&lt;p&gt;Hugo can read your configuration as JSON, YAML or TOML. Hugo supports parameters custom configuration too. Refer to the &lt;a href=&#34;http://www.itspedia.com/overview/configuration/&#34;&gt;Hugo configuration documentation&lt;/a&gt; for details.&lt;/p&gt;
&lt;h2 id=&#34;set-your-configuration-publish-folder-to-_site&#34;&gt;Set your configuration publish folder to &lt;code&gt;_site&lt;/code&gt;&lt;/h2&gt;
&lt;p&gt;The default is for Jekyll to publish to &lt;code&gt;_site&lt;/code&gt; and for Hugo to publish to &lt;code&gt;public&lt;/code&gt;. If, like me, you have &lt;a href=&#34;http://blog.blindgaenger.net/generate_github_pages_in_a_submodule.html&#34;&gt;&lt;code&gt;_site&lt;/code&gt; mapped to a git submodule on the &lt;code&gt;gh-pages&lt;/code&gt; branch&lt;/a&gt;, you&amp;rsquo;ll want to do one of two alternatives:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Change your submodule to point to map &lt;code&gt;gh-pages&lt;/code&gt; to public instead of &lt;code&gt;_site&lt;/code&gt; (recommended).&lt;/p&gt;
&lt;pre&gt;&lt;code&gt; git submodule deinit _site
 git rm _site
 git submodule add -b gh-pages git@github.com:your-username/your-repo.git public
&lt;/code&gt;&lt;/pre&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Or, change the Hugo configuration to use &lt;code&gt;_site&lt;/code&gt; instead of &lt;code&gt;public&lt;/code&gt;.&lt;/p&gt;
&lt;pre&gt;&lt;code&gt; {
     ..
     &amp;quot;publishdir&amp;quot;: &amp;quot;_site&amp;quot;,
     ..
 }
&lt;/code&gt;&lt;/pre&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;h2 id=&#34;convert-jekyll-templates-to-hugo-templates&#34;&gt;Convert Jekyll templates to Hugo templates&lt;/h2&gt;
&lt;p&gt;That&amp;rsquo;s the bulk of the work right here. The documentation is your friend. You should refer to &lt;a href=&#34;http://jekyllrb.com/docs/templates/&#34;&gt;Jekyll&amp;rsquo;s template documentation&lt;/a&gt; if you need to refresh your memory on how you built your blog and &lt;a href=&#34;http://www.itspedia.com/layout/templates/&#34;&gt;Hugo&amp;rsquo;s template&lt;/a&gt; to learn Hugo&amp;rsquo;s way.&lt;/p&gt;
&lt;p&gt;As a single reference data point, converting my templates for &lt;a href=&#34;http://heyitsalex.net/&#34;&gt;heyitsalex.net&lt;/a&gt; took me no more than a few hours.&lt;/p&gt;
&lt;h2 id=&#34;convert-jekyll-plugins-to-hugo-shortcodes&#34;&gt;Convert Jekyll plugins to Hugo shortcodes&lt;/h2&gt;
&lt;p&gt;Jekyll has &lt;a href=&#34;http://jekyllrb.com/docs/plugins/&#34;&gt;plugins&lt;/a&gt;; Hugo has &lt;a href=&#34;http://www.itspedia.com/doc/shortcodes/&#34;&gt;shortcodes&lt;/a&gt;. It&amp;rsquo;s fairly trivial to do a port.&lt;/p&gt;
&lt;h3 id=&#34;implementation&#34;&gt;Implementation&lt;/h3&gt;
&lt;p&gt;As an example, I was using a custom &lt;a href=&#34;https://github.com/alexandre-normand/alexandre-normand/blob/74bb12036a71334fdb7dba84e073382fc06908ec/_plugins/image_tag.rb&#34;&gt;&lt;code&gt;image_tag&lt;/code&gt;&lt;/a&gt; plugin to generate figures with caption when running Jekyll. As I read about shortcodes, I found Hugo had a nice built-in shortcode that does exactly the same thing.&lt;/p&gt;
&lt;p&gt;Jekyll&amp;rsquo;s plugin:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;module Jekyll
  class ImageTag &amp;lt; Liquid::Tag
    @url = nil
    @caption = nil
    @class = nil
    @link = nil
    // Patterns
    IMAGE_URL_WITH_CLASS_AND_CAPTION =
    IMAGE_URL_WITH_CLASS_AND_CAPTION_AND_LINK = /(\w+)(\s+)((https?:\/\/|\/)(\S+))(\s+)&amp;quot;(.*?)&amp;quot;(\s+)-&amp;gt;((https?:\/\/|\/)(\S+))(\s*)/i
    IMAGE_URL_WITH_CAPTION = /((https?:\/\/|\/)(\S+))(\s+)&amp;quot;(.*?)&amp;quot;/i
    IMAGE_URL_WITH_CLASS = /(\w+)(\s+)((https?:\/\/|\/)(\S+))/i
    IMAGE_URL = /((https?:\/\/|\/)(\S+))/i
    def initialize(tag_name, markup, tokens)
      super
      if markup =~ IMAGE_URL_WITH_CLASS_AND_CAPTION_AND_LINK
        @class   = $1
        @url     = $3
        @caption = $7
        @link = $9
      elsif markup =~ IMAGE_URL_WITH_CLASS_AND_CAPTION
        @class   = $1
        @url     = $3
        @caption = $7
      elsif markup =~ IMAGE_URL_WITH_CAPTION
        @url     = $1
        @caption = $5
      elsif markup =~ IMAGE_URL_WITH_CLASS
        @class = $1
        @url   = $3
      elsif markup =~ IMAGE_URL
        @url = $1
      end
    end
    def render(context)
      if @class
        source = &amp;quot;&amp;lt;figure class=&#39;#{@class}&#39;&amp;gt;&amp;quot;
      else
        source = &amp;quot;&amp;lt;figure&amp;gt;&amp;quot;
      end
      if @link
        source += &amp;quot;&amp;lt;a href=\&amp;quot;#{@link}\&amp;quot;&amp;gt;&amp;quot;
      end
      source += &amp;quot;&amp;lt;img src=\&amp;quot;#{@url}\&amp;quot;&amp;gt;&amp;quot;
      if @link
        source += &amp;quot;&amp;lt;/a&amp;gt;&amp;quot;
      end
      source += &amp;quot;&amp;lt;figcaption&amp;gt;#{@caption}&amp;lt;/figcaption&amp;gt;&amp;quot; if @caption
      source += &amp;quot;&amp;lt;/figure&amp;gt;&amp;quot;
      source
    end

&lt;p&gt;is written as this Hugo shortcode:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;&amp;lt;!-- image --&amp;gt;
&amp;lt;figure {{ with .Get &amp;quot;class&amp;quot; }}class=&amp;quot;{{.}}&amp;quot;{{ end }}&amp;gt;

&amp;lt;!-- image --&amp;gt;
&lt;/code&gt;&lt;/pre&gt;
&lt;h3 id=&#34;usage&#34;&gt;Usage&lt;/h3&gt;
&lt;p&gt;I simply changed:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{% image full http://farm5.staticflickr.com/4136/4829260124_57712e570a_o_d.jpg &amp;quot;One of my favorite touristy-type photos. I secretly waited for the good light while we were &amp;quot;having fun&amp;quot; and took this. Only regret: a stupid pole in the top-left corner of the frame I had to clumsily get rid of at post-processing.&amp;quot; -&amp;gt;http://www.flickr.com/photos/alexnormand/4829260124/in/set-72157624547713078/ %}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;to this (this example uses a slightly extended version named &lt;code&gt;fig&lt;/code&gt;, different than the built-in &lt;code&gt;figure&lt;/code&gt;):&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;{{% fig class=&amp;quot;full&amp;quot; src=&amp;quot;http://farm5.staticflickr.com/4136/4829260124_57712e570a_o_d.jpg&amp;quot; title=&amp;quot;One of my favorite touristy-type photos. I secretly waited for the good light while we were having fun and took this. Only regret: a stupid pole in the top-left corner of the frame I had to clumsily get rid of at post-processing.&amp;quot; link=&amp;quot;http://www.flickr.com/photos/alexnormand/4829260124/in/set-72157624547713078/&amp;quot; %}}
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;As a bonus, the shortcode named parameters are, arguably, more readable.&lt;/p&gt;
&lt;h2 id=&#34;finishing-touches&#34;&gt;Finishing touches&lt;/h2&gt;
&lt;h3 id=&#34;fix-content&#34;&gt;Fix content&lt;/h3&gt;
&lt;p&gt;Depending on the amount of customization that was done with each post with Jekyll, this step will require more or less effort. There are no hard and fast rules here except that &lt;code&gt;hugo server --watch&lt;/code&gt; is your friend. Test your changes and fix errors as needed.&lt;/p&gt;
&lt;h3 id=&#34;clean-up&#34;&gt;Clean up&lt;/h3&gt;
&lt;p&gt;You&amp;rsquo;ll want to remove the Jekyll configuration at this point. If you have anything else that isn&amp;rsquo;t used, delete it.&lt;/p&gt;
&lt;h2 id=&#34;a-practical-example-in-a-diff&#34;&gt;A practical example in a diff&lt;/h2&gt;
&lt;p&gt;&lt;a href=&#34;http://heyitsalex.net/&#34;&gt;Hey, it&amp;rsquo;s Alex&lt;/a&gt; was migrated in less than a &lt;em&gt;father-with-kids day&lt;/em&gt; from Jekyll to Hugo. You can see all the changes (and screw-ups) by looking at this &lt;a href=&#34;https://github.com/alexandre-normand/alexandre-normand/compare/869d69435bd2665c3fbf5b5c78d4c22759d7613a...b7f6605b1265e83b4b81495423294208cc74d610&#34;&gt;diff&lt;/a&gt;.&lt;/p&gt;
