A command-line tool that analyzes Ruby code documentation and suggests improvements without enforcing strict rules.
Inch is a command-line utility that analyzes Ruby codebases to suggest where inline documentation can be improved. It evaluates documentation completeness using a grade system (A to U) and prioritizes suggestions based on code importance, helping developers enhance docs without enforcing strict formats or full coverage.
Ruby developers and teams who want to maintain or improve their code documentation in a flexible, non-intrusive way, especially those using YARD, RDoc, or TomDoc styles.
Developers choose Inch for its relaxed, suggestion-based approach that avoids coverage mandates, supports multiple documentation styles, and focuses on high-priority improvements, making it less overwhelming than strict coverage tools.
A documentation analysis tool for the Ruby language
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports YARD, RDoc, TomDoc, and unstructured comments without enforcing syntax, as shown in README examples where different styles all score an A.
Uses arrow indicators (↑ for high priority) to highlight critical objects like public methods, helping developers focus on impactful improvements first.
Assigns grades A to U based on completeness, avoiding binary coverage scores and allowing for partial documentation to still receive high marks.
Provides grade distribution charts via the stats subcommand, offering a big-picture view of documentation health without oversimplifying.
Cannot verify if documentation is accurate, useful, or includes working code examples; the Limitations section admits it only checks for presence and basic structure.
Exclusively analyzes Ruby codebases, making it unsuitable for multi-language projects or teams using other programming languages.
The relaxed approach may lead to grades that don't align with team-specific standards, as it avoids strict formatting rules and can miss nuanced quality issues.
