I run a lot of commands from the command line. Many of the graphical
applications such as gedit use glib. I get a ton of spam on the terminal
when I run them that look like:
(gedit:5700): Gtk-WARNING **: ...
I've written a patch to allow the user to skip these messages if desired.
What you do is
patch -Np2 ../glib.patch
Continue with regular glib build/install
This patch should change nothing unless the environment variable
GLIB_LOG_LEVEL is set. The values are numeric:
0 Emergency
1 Alert
2 Critical
3 Error
4 Warning
5 Notice
6 Info
7 Debug
So if you want to disable messages at the Warning level or above, you use:
export GLIB_LOG_LEVEL=4
I'm asking for feedback to see if this is worth putting in BLFS or perhaps
offering it upstream.
Feedback welcome.
