Message

colorize: add ability to colorize multiple files into less (#7662)

cless is an alias for a colorized less wrappper: colorize_via_pygmentize_less.
Note that cless opens many files as independent files, navigatable with `:n` and `:p`.

 7 With this plugin you can syntax-highlight file contents of over 300 supported languages and other text formats.
 8 
 9+Colorize will highlight the content based on the filename extension. If it can't find a syntax-highlighting
10+method for a given extension, it will try to find one by looking at the file contents. If no highlight method
11+is found it will just cat the file normally, without syntax highlighting.
12+
13 To use it, add colorize to the plugins array of your zshrc file:
