Description Pádraig Brady 2012-08-19 12:16:13 UTC
Created attachment 605480 [details] script to enable feature I've attached a small patch to initscripts enabling the "256 color terminals" Fedora 18 feature. You should be able to apply using: git am < term256.diff I tested it with the 25 xterms I could find in Fedora, with both csh and sh shells, and all xterms are handled appropriately. Users logging in remotely are not impacted. For details of the feature see: https://fedoraproject.org/wiki/Features/256_Color_Terminals
Comment 1 Kevin Raymond 2012-09-03 19:18:09 UTC
Is there any plan to take this patch into account before the F18 Beta release? Thanks,
Comment 2 Bill Nottingham 2012-09-10 17:53:21 UTC
Apologies - have been traveling and tied up in other things. This will happen before beta, but not before alpha.
Comment 3 Bill Nottingham 2012-09-14 20:13:12 UTC
Added in git, with tweaks to the comments suggesting methods of setting SEND256... that don't involve editing the packaged profile.d files.
Comment 4 Pádraig Brady 2012-09-14 20:32:47 UTC
I checked your amendments at http://git.fedorahosted.org/cgit/initscripts.git/commit/?id=c819f19 which make lots of sense. thanks!

Comment 6 Ozan Çağlayan 2012-12-19 18:48:21 UTC
I've found a culprit in here. If I put a self-made .dircolors in my home directory, normally /etc/profile.d/colorls.sh should set it but this is broken in F18. The reason is that term256.sh is alphabetically after colorls.sh in /etc/profile.d which means that it is executed after colorls.sh which calls "dircolors" from coreutils. dircolors utility fails if $TERM != one of the TERM's written in .dircolors. And bingo, no colors at all in the terminal. Rename the file to 00-term256.sh and it's fixed.
Comment 7 Bill Nottingham 2012-12-19 19:26:56 UTC
This is because the local file doesn't have a current list of colorizable terms, correct?
Comment 8 Pádraig Brady 2012-12-19 21:47:39 UTC
Drats. I did all my testing with /etc/profile.d/256color.sh and switched to term256.sh at the last minute :( I agree that this script should run early, and renaming to 00-term256.sh would be a good way to do that. I don't fully understand why Ozan has no colors. If dircolors is run from colorls.sh, how could term256.sh impact here?
Comment 9 Ondrej Vasik 2012-12-20 09:05:09 UTC
Ozan: Could you please be more specific what's broken on colorls.sh in F18?
Comment 10 Ozan Çağlayan 2012-12-20 09:23:32 UTC
Okay I think I couldn't explain the problem in a clear way, here it is: - There is no problem if you don't put a custom .dircolors/.dir_colors in your $HOME directory. - Just copy /etc/DIRCOLORS.256color into your $HOME as .dircolors/.dir_colors, open a new shell in gnome-terminal and you'll see that you have no colors. This default DIRCOLORS lists all the colorizable terms: TERM putty-256color TERM rxvt-256color TERM rxvt-unicode-256color TERM rxvt-unicode256 TERM screen-256color TERM xterm-256color TERM gnome-256color But the problem is that /etc/profile.d/term256.sh is executed after /etc/profile.d/colorls.sh. This is a problem because it is term256.sh which sets $TERM to xterm-256color. So when colorls.sh is executed the $TERM is still plain 'xterm'. Line 33 of colorls.sh calls: eval "`dircolors --sh "$COLORS" 2>/dev/null`" This fails to export LS_COLORS as dircolors returns an empty LS_COLORS because the TERM environment variable which is plain 'xterm' doesn't have a match in the colorizable TERM list from the .dir_colors. I don't know if /etc/profile.d scripts should have a dependency ordering between themselves, it is up to you to decide where this should be fixed.
Comment 11 Pádraig Brady 2012-12-20 10:17:14 UTC
OK so this doesn't look like a regression at least. I get the same behavior with /etc/profile.d/term256.sh present or not. I.E. if you: cp /etc/DIR_COLORS.256color ~/.dir_colors and you haven't otherwise set TERM=xterm-256color then colorls.sh will not setup the LS_COLORS env variable, and thus you'll get the _default set_ of ls colors. But yes to auto set LS_COLORS to the 256 color set (including a 256 color set in ~/.dir_colors) we'll need to rename term256.sh to run earlier. thanks.
Comment 12 Ozan Çağlayan 2012-12-20 11:49:10 UTC
Well actually you don't get the default set of LS_COLORS because the colorls.sh returns before setting the ll,ls,l. aliases, so you end up with ll, ls and l. without --color=auto: eval "`dircolors --sh "$COLORS" 2>/dev/null`" [ -z "$LS_COLORS" ] && return <-- Here the script returns
Comment 13 Pádraig Brady 2012-12-20 12:31:47 UTC
Yes fair point (I had a local ls alias masking that fact). So we've got all the details now I think, and it's not a regression from previous behavior, but still needs to be fixed up. thanks.
Comment 14 Bill Nottingham 2012-12-20 15:21:54 UTC
So, a simple move of term256.sh to 256term.sh will suffice?
Comment 15 Pádraig Brady 2012-12-20 17:28:05 UTC
Yes. POSIX and bash guarantee the glob will sort before colorls.sh.
Comment 16 Pádraig Brady 2013-01-03 19:08:24 UTC
Created attachment 672156 [details] ensure ls auto enables 256 colors trivial patch attached in case it saves some typing
Comment 17 Bill Nottingham 2013-01-03 19:21:10 UTC
Fixed in git, likely won't make final unless there's a slip or another blocker.

Comment 21 Pádraig Brady 2014-11-21 03:29:46 UTC
This breaks in Fedora 21 due to https://git.gnome.org/browse/gnome-terminal/commit/?id=1d5c1b6ca6373c1301494edbc9e43c3e6a9c9aaf I suppose we could augment the script to check $VTE_VERSION though I've asked the author of the commit above to comment first.
Comment 22 Pádraig Brady 2014-11-22 04:14:45 UTC
Created attachment 960055 [details] used 256 colors by default with gnome-terminal
Comment 23 Pádraig Brady 2014-11-22 04:18:30 UTC
Reopening this as the feature is broken on the default terminal in Fedora 21. The simple patch above should suffice, as the author of the gnome-terminal patch referenced above indicated that he wasn't considering reinstating the COLORTERM env variable.
