What it is

csscss is a Ruby-based CSS static analyzer that identifies redundant declarations across CSS rulesets by parsing stylesheets and reporting which selectors share duplicate property definitions. It works on plain CSS, Sass/SCSS, and LESS files, helping developers eliminate unused and duplicated styling rules to maintain cleaner codebases. Monolithic gem structure: lib/csscss/parser/ contains modular CSS property parsers (border.rb, margin.rb, font.rb, etc.) that inherit from base.rb; lib/csscss/redundancy_analyzer.rb orchestrates analysis; CLI entry point is lib/csscss/cli.rb; test/ mirrors this structure with parser-specific unit tests.

Start here

Open these first:

• lib/csscss.rb — Main entry point that orchestrates the CSS analysis pipeline from parsing to reporting.
• lib/csscss/cli.rb — Command-line interface handler that processes arguments and invokes the core analyzer.
• lib/csscss/redundancy_analyzer.rb — Core logic that detects duplicate CSS declarations across rulesets.
• lib/csscss/parser/css.rb — CSS parser that tokenizes and extracts declarations from stylesheet input.
• lib/csscss/parser/base.rb — Base class defining the parser interface and common parsing utilities.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repo, then install via gem (evidence: Gemfile and csscss.gemspec present): gem install csscss or bundle install after cloning. Run bin/csscss against a CSS file: csscss path/to/styles.css.

Daily commands:

Command-line tool: csscss <file_or_url> to run analysis. Options: -v for verbose (show matching rules), -n <number> to set minimum match threshold. Remote files via URL supported. No server or daemon mode evident.

Key cautions & unknowns

• Stale — last commit 8y ago
• Single-maintainer risk — top contributor 89% of recent commits
• Scorecard: marked unmaintained (0/10)
• Ruby version constraint: declared as Ruby 1.9.x minimum in README (now obsolete; verify actual supported versions in .ruby-version file, not shown). LESS parsing requires a JavaScript runtime (therubyracer on most…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
