ruby-github-linguist - 7.27.0-1+b5 main

Language detection: ruby-github-linguist defines a list of all languages
known to GitHub in a yaml file. In order for a file to be highlighted, a
language and a lexer must be defined there.
.
Syntax Highlighting: The actual syntax highlighting is handled by the
Pygments wrapper, ruby-pygments.rb. It also provides a Lexer abstraction that
determines which highlighter should be used on a file.
.
Stats: The Language stats bar that you see on every repository is built by
aggregating the languages of each file in that repository. The top language in
the graph determines the project's primary language.
.
Ignore vendored files: Checking other code into your git repo is a common
practice. But this often inflates your project's language stats and may even
cause your project to be labeled as another language. ruby-github-linguist is
able to identify some of these files and directories and exclude them.
.
Generated file detection: Not all plain text files are true source files.
Generated files like minified js and compiled CoffeeScript can be detected and
excluded from language stats. As an extra bonus, these files are suppressed in
diffs.
