Rho ~ Version 3.0.1

Description

Rho is a LaTeX2e document class designed for the creation of professional, well-structured research articles, technical/lab reports, and academic documentation.

The main features of the class include:

• A self-contained structure, where the class file and custom packages are distributed within a single folder for easy setup and portability.
• STIX2 as the primary serif font, providing excellent readability for body text and mathematical content.
• Custom environments for notes, information blocks, and structured content.
• Enhanced code presentation, with custom color schemes for multiple programming languages (e.g., MATLAB, C, C++, TeX).
• Integration of a dedicated translation package that simplifies the translation of selected document elements, allowing automatic adaptation to the document language.
• Compatible with external editors such as TeXstudio (additional setup may be required).

Updates Log

Version 3.0.1 (15/04/2026)

A small but important compatibility fix for Spanish documents.

1. Replaced all occurrences of ~ with \nobreakspace in command definitions throughout rho.cls and rhobabel.sty. The ~ character becomes active under babel with the spanish option, causing compilation errors when used inside \newcommand definitions.

Version 3.0.0 (24/02/2026)

A new year brings major improvements and new features to rho-class!

1. The \journalname{} command has been renamed to \doctype{} for improved clarity and semantic consistency.
2. A new \docinfo{} command has been introduced to provide a flexible block for supplementary metadata. Positioned at the bottom of the first page, it works seamlessly alongside the new \corres{} command.
3. The corresponding author section, previously located above the abstract, has been removed and integrated into the new \docinfo{} block.
4. A new \corres{} command has been added as a flexible alternative to \thanks{}, allowing for easier positioning and customization of corresponding author details.
5. New commands have been introduced to display additional document metadata in the footer of the first page (\journalname{}, \journal{}, \vol{}, \no{}).
6. New cross-reference commands have been implemented for figures, tables, code listings, and equations, with hyperlinks applied to both the label and the reference number. Additional commands are provided in rhobabel.sty to configure language and style.
7. A new command has been introduced for inline code formatting, providing a visual style distinct from both normal text and traditional verbatim to improve readability.
8. All section titles are now displayed in uppercase to ensure visual consistency across the document.
9. All environments feature a more modern design while preserving their original visual identity.
10. All environments and the abstract now feature a subtle rounded border, adding a modern and polished touch to the overall template design.
11. The default \sffamily font has been changed from Helvetica to Fira Sans, providing a more modern and flexible appearance.
12. The font used for code has been updated to Fira Mono, a widely adopted monospaced typeface that improves readability and visual consistency.
13. The numeric-comp option has been enabled so that multiple references can appear compressed in the same bracket.
14. The minted package has been added to provide enhanced code formatting and improved syntax highlighting.
15. The configuration of the listings package has been refined; it remains a fully supported alternative to minted.
16. The rhoenvs.sty package has been completely rewritten to optimize performance and improve environment styling.
17. All packages are now organized into clearly defined sections within rho.cls. Non-essential packages have been commented out and moved to an "Optional-, extra- packages" section to reduce compilation time.
18. The class source code has been optimized and cleaned up to enhance maintainability and provide a better user experience.

Version 2.1.2 (28/02/2025)

1. Added an arrow when there is a line break when a code is inserted.
2. Numbers in the codes are now shown in blue to differentiate them.
3. Keywords are now shown in bold for codes.
4. The lstset for matlab language was removed for better integration
5. The tabletext command will now display the text in italics.

Version 2.1.1 (01/09/2024)

1. Journalname has modified its font size to improve the visual appearance of the document.
2. Solution of non-justified abstract. Added \justify command in line 307 (rho.cls).

Version 2.1.0 (14/08/2024)

1. The language boolean function has been removed from rhobabel.sty and the language is now manually set in the main.tex to avoid confusion.
2. The line numbering boolean function has been removed and replaced by the command \linenumbers in the main.tex.
3. The graphics path option was added in rho-class/rho.cls/packages for figures.
4. Small details have been added to improve the layout of the document.

Version 2.0.0 (21/05/2024)

2. Automatic adjustments if the followings commands are not declared in the preamble:
   • \corres{}, \doi{}, \received{}, \reviewed{}, \accepted{}, \published{}, \license{}
   • \journalname{}
   • \dates{}
   • \keywords{}
3. New command \setbool{corres-info}{t/f} to disable or enable the corresponding author section (main.tex).
   • If the corresponding author is enable: \setbool{corres-info}{true}

4. New command \setbool{linenumbers}{t/f} to disable or enable line numbering (main.tex).
   • If the line numbering is enable: \setbool{linenumbers}{true}
   • If the line numbering is disable: \setbool{linenumbers}{false}
