A CLI Tool for Executing Code Blocks in Markdown Files.

RunMD is a command-line tool designed to extract and execute code blocks from Markdown files. It's particularly useful for managing and running code snippets embedded in documentation or notes.

⚠ RunMD is intended for use with scripting languages only (e.g., Shell, Python, Ruby, JavaScript). It does not support compiled languages (e.g., C, C++, Java) as it cannot handle compilation and execution steps.

⚠ RunMD is different from interactive notebooks like Jupyter or Zepplin. Each code block is independent and executed separately.

Synopsis

runmd [COMMAND] [OPTIONS]

Commands

RUN

• blockname: The name of the code block to run, or "all" to run all blocks.
• -t [TAG], --tag [TAG]: Specify the tag of the code blocks to run.
• -f [FILE], --file [FILE]: Specify the path to the Markdown file containing the code blocks.
• --env VAR=value ...: Optional environment variables to set during the execution.

SHOW

Displays the content of a specified code block.

runmd show [blockname] [--file FILE]

• blockname: The name of the code block to display.
• -f [FILE], --file [FILE]: Specify the path to the Markdown file.

LIST

Lists all the code blocks in a Markdown file.

runmd list [tag] [--file FILE]

• -t [TAG], --tag [TAG]: Optional tag to filter the list of code blocks.
• -f [FILE], --file [FILE]: Specify the path to the Markdown file.

HIST

Displays or clears the history of runmd commands.

runmd hist [id] [--clear]

• id: command line entry in history to execute.
• --clear: Clears definitely all the command line entries in history.

VAULT

Encrypt/Decrypt a markdown file using a password.

runmd vault --encrypt README.md --outfile README.enc

runmd vault --decrypt README.enc --outfile README.dec

• -e [FILE], --encrypt [FILE]: Encrypt the specified markdown file.
• -d [FILE], --decrypt [FILE]: Decrypt the encrypted file.
• -o [FILE], --outfile [FILE]: Optional output file name (default: add .vault suffix to input file name).

Other options

Other options are quite standard:

• --help: to show the help message
• --version: to get the installed version of runmd

Add executable code block

To add an executable code block to your Markdown file, use the following syntax:

# My executable code block
    ```sh {name=export-echo,tag=example}
    EXPORT MYSTR="a simple export and echo"
    echo $MYSTR
    ```

List Code Blocks

To list all code block names in Markdown files within the current directory:

runmd list

Show a Specific Code Block

To display the content of a specific code block:

runmd show <code-block-name>

Run a Specific Code Block

To execute a specific code block by name:

runmd run <code-block-name>

Run all code blocks with a given tag

To execute a specific code block by name:

runmd run -t <tag>

Run all code blocks

To execute a specific code block by name:

runmd run all

Run a Specific Code Block with nvironment variable

To execute a specific code block by name:

runmd run <code-block-name> --env <KEY1>=<VALUE1> <KEY2=VALUE2>

Run all code blocks

To execute all code blocks in Markdown files within the current directory:

runmd run all

Configuration

You can customize how different scripting languages are executed by creating a configuration file at ~/.config/runmd/config.json. Here’s an example configuration:

{
    "sh": {
        "command": "bash",
        "options": ["-c"]
    },
    "python": {
        "command": "python",
        "options": []
    },
    "ruby": {
        "command": "ruby",
        "options": []
    }
}

Troubleshooting

• No Output: Ensure the Markdown code blocks are correctly formatted and the specified commands are valid for the environment.
• Permission Denied: Check if you have the required permissions to execute the commands in the code blocks.
