Rouge is a pure Ruby syntax highlighter supporting over 200 languages, with output to HTML or ANSI 256-color text. Its HTML output is compatible with Pygments stylesheets, and it serves as Jekyll's default highlighter.

Use cases

• highlight code snippets in a Ruby web app
• syntax highlight code in Jekyll blog posts
• colorize code in the terminal
• generate CSS for code highlighting styles
• replace Pygments in a Ruby project
• render code blocks as HTML with themes

When to choose

• you need syntax highlighting in a Ruby project without Python dependencies
• you use Jekyll and want its default highlighter
• you want Pygments-compatible HTML output with existing stylesheets
• you need ANSI-colored code in terminal output

When to avoid

• your project is not in Ruby and Pygments is available
• you need highlighting for a language Rouge does not support
• you need extremely high-performance highlighting of very large files
