Detailed Description

This tool can be used to hide certain errors and warnings from your console. Many of us really do not care about those Gtk-WARNINGS, which we cannot really do anything about, except parse out with such a tool.

To use, create an alias in your ~/.bashrc file:

alias gvim="hide-warnings gvim"
alias meld="hide-warnings meld"
...any command that generates Gtk-WARNINGS...

If you want to parse out other things, you may change the default regex ('gtk-wanring|gtk-critical|glib-gobject-warning|^$') with whatever you want. Use the –regex command line option for that purpose:

alias gimp="hide-warnings --regex 'cannot change name of operation class|glib-gobject-warning|gtk-warning|^$' gimp"

If your command starts with a dash (-), then use – on the command line before your command:

alias weird="hide-warnings --regex 'forget|that' -- -really-weird'

Todo:

Transform the command line handling to make use of the advgetopt. I wrote this tool in a separate project at first but wanted to share it and make it an example on how to use advgetopt but as we can see at the moment it's not yet converted... For now, it's a C++ file at least.
