I'd prefer patches to contrib/ sections to be CC'ed to the
owners of them (in this case that would be Jeff King) to be
Acked, since I do not actively maintain anything under contrib/
myself.

Jeff, are you Ok with Pierre's two patches?

I find it confusing that you split vertically, especially if I work in
 small terminals.
I would prefere a horizontal split, thats why I changed it to the way
to the way it is
handled in the svn.vim commit case:

below new

Why changing directory? I had to remove the cd .. to make it work. Otherwise
git diff couldn't find the repository.

because for me, wherever I'm from, the cwd is .git/ but it's maybe due 
to the fact that I use autochdir, I don't know.

Wouldn't it make sense to use something like 'git-rev-parse --git-dir' or
'git-rev-parse --show-cdup' to get to the root of the repository?

Yes it does, SungHyun Nam already sent a patch to me about that, that is 
quite interesting. I've merged it partly, and will make that commit 
plugin slightly better, so that people can:
 1/ trig it by hand
 2/ chose if the split is vertical or horizontal (I always have very big
    terms with a lot of vertical splits in vim, so I like the latter,
    other prefer the former)
 3/ chose via a let g:gitcommit_diff_mode or sth like that in the vimrc
    if that has to spawn automatically (0: none, 1: horiz split, 2: vert
    split)

and that time, I'll send that to the git contrib/vim maintainer so that 
I won't bother the list too much :)

a corrected version of the commit file wrt the cwd is on my site 
already, with a bit of SungHyun changes[1].

so there is a contrib/vim maintainer ? Sorry I'm new on git list
(though Pierre gave me some hints already with git/vim).

I'm interested in testing more of these goodies. Because I
actually use git now on a daily basis for tcl/verilog/EDA
together with (g)vim.

I'd like particularly to know if a git-explorer type of plugin makes
sense for (g)vim and would like in this case be part of the team
developping it... using git of course :)

If you have git sources, check contrib/README please.

What I asked Pierre was to CC the patch to Jeff King who did
contrib/vim -- it was "send it to him too", and not "do not send
it to me".  I do not actively use vim myself so I am a wrong
person to judge patches to that part of the source tree.

Apparently Pierre seems to have thought that I thought patches
to the contrib/ part is "bothering the list", but that was not
my intention.  I believe showing your patches for review by
wider audiences is a good thing.

contrib/vim patches, replace the previous set

[Pierre Habouzit]

  here is a brand new set of patches, the same update on the syntax
file, and an enhanced ftplugin that is very configureable.

  Those two patches replace the two previous ones.

Make the ftplugin right wrt gitdir

sorry for the mess, I'm a bit tired :)
Here is a third patch to fix the plugin to find the git-dir properly.

Also add a nice shortcut to quit that buffer.

Dear diary, on Tue, Oct 17, 2006 at 11:48:51PM CEST, I got a letter
where Christian MICHON <christian.michon@gmail.com> said that...

Personally, I'd say "just use tig". :-)

If you insist on living instide vim, that particular script comes from
the age before git-show and git-cat-file -p so it would probably make
sense to move the bulk of the functionality there.

I think this is a good change (along with commenting), but please write
a more descriptive commit message than "be more vim-ish" (I wouldn't
mind seeing this and the highlighting change broken into two patches,
since they are functionally completely unrelated).

> +syn region gitSignedOff start=/^Signed-off-by:/ end=/$/ contains=gitAuthor,gitEmail
> +syn region gitAuthor contained start=/\s/ end=/$/

You mention gitEmail but never define it. Are people using other things
besides Signed-off-by? I think we might do better to simply write:
  syn region gitCommentHeader start=/^[^ ]\+:/ end=/$/ contains=gitCommentValue
  syn region gitCommentValue contained start=/\s/ end=/$/

Highlighting only the header is inconsistent with other highlighting
(e.g., all of "new file: foo" is highlighted), but it looks so ugly to
highlight the whole line, so I think this is fine.

Right, that's the "be more robust" patch which applies on top of
something else (presumably "nice ftplugin for vim"), but the last one I
got of that (<11611319761977-git-send-email-madcoder@debian.org>) causes
vim errors and you immediately followed up with "that's still not the
good one." Where is that patch?

hmm I see, curious though, I must have do sth stupid :|

well the result file is here: 
http://madism.org/~madcoder/dotfiles/vim/ftplugin/git.vim

I've not access to my git repo from here, feel free to grab it and 
commit it, I don't care if there is not my name on it.

and as of gitEmail you're right I don't use it, I wanted to to hilight 
the email address in the gitAuthor zone, but well, basically, it sucks, 
that makes too many colors.

Do things like tw really have anything to do with the ftplugin?
Shouldn't they instead go into the user's vimrc?

This all looks OK to me, but then I don't really know vim script very
well. :)

This procedure seems a bit hack-ish and fragile. I think the chdir is
necessary not just to handle autochdir, but also because we want to do
any diff from the top-level instead of a subdir. Why do we
unconditionally set LANG=C? What about quoting for the file list?

In general, is this really that much nicer than simply using the '-v'
flag to git-commit?

This should probably handle the case where g:git_diff_spawn_mode is not
defined (otherwise vim complains loudly):
  if exists("g:git_diff_spawn_mode")
     " do nothing
  elseif g:git_diff_spawn_mode == 1
etc.
