Bug 433974 – app-portage/gentoolkit - add '--color' switch in utilities

• Product: Portage Development
• Status: RESOLVED FIXED

[Description trismarck 2012-09-05 00:09:16 UTC]

Hi,

would it be possible to add a --color switch to programs like 'equery' inside the gentoolkit package, so, if the output of the program is redirected to a pipe, that program would properly encode coloring into the pipe?
I.e.
equery list mc | less -r

This will currently display the output of the equery command without coloring the output.
Note that 'emerge' already has a '--color y' switch.

Set the -N, switch to turn off pipe detection.  But that usually also changes the output, since output is usually quieted some for pipes as compared to normal output.  But using -N will turn colors back on.

equery -N list mc | less -r

Hi Brian,

this is the effect of the '--no-pipe' switch:

I'm using equery-0.3.0.6-r3.

Since you don't have it installed (equery default, search only installed pkgs) you need to add the -p switch for list so it searches the entire portage tree.

equery -N list -p mc | less -r

I know I don't have it installed, I just wanted to show you that colors are not working :) .

Yes, we saw it wasn't.  We both wrongly thought the -N switch restored colors.

Anyway, Paul Varner fixed it today.  So if you use the the -N switch but don't want colors, you will need to also add the -C switch to turn them off.

fixed in commit:

You can get the change now by emerging gentoolkit-9999.

There are a few more small changes/bugfixes since -0.3.0.6-r3.  Do not worry it will be too unstable, we have not yet started work on changes for -0.3.1.

Actually there is one unstable change in gentoolkit-9999.  revdep-rebuild is a new python version which can miss things.  To be safe, you can run revdep-rebuild.sh which is the stable bash version of revdep-rebuild.  Other than that, gentoolkit-9999 is very close to the current stable version of gentoolkit.

Released in gentoolkit-0.3.0.7
