Please provide an option to run as filter

[jdevera]

Colorgcc could have a filter mode, reading gcc output from stdin and colorizing it. This allows the use of colorgcc only in particular occasions and also allows its use in constrained environments where the main gcc is not editable and gcc is called directly with its full path.

I would like to have this option too!

Edit:
I created a crude version of this now, check it out here: https://github.com/sschaetz/colorgcc/blob/filter/colorize.pl
