emacs and git...

[Francis Moreau]

Hi,

I guess it's a dumb...

I know that some of you work within emacs. I tried to use git iniside
a emacs shell (M-x shell) and had a weid behaviour:

$ git diff
WARNING: terminal is not fully functional
-  (press RETURN)
diff --git a/.lde/bin/cmd-version b/.lde/bin/cmd-version^[[m
index a6ce3f8..687112d 100755^[[m
--- a/.lde/bin/cmd-version^[[m
+++ b/.lde/bin/cmd-version^[[m
@@ -54,7 +54,7 @@ gdb_version () {^[[m
[snip]

I'm not using diff color option.

Can anybody shed some light ?

thanks

DVC has an embryo of a git mode (development not active at the
moment).

  http://download.gna.org/dvc/

There's also a git.el which I didn't try yet.

I use M-x shell on a regular basis, and have learned to add the following
three items to my .emacs wherever I'm at:

  (setenv "PAGER" "/bin/cat")
  (setenv "EDITOR" "/opt/emacs/bin/emacsclient") ; `which emacsclient`
  (server-start)

Unless you do the first line, programs that like to push things through "less"
or "more" do some pretty nasty things.  And those last two are nice, because
you can use "git-commit" directly in the shell window, and it'll pop up an
emacs buffer.  Read up on emacs-server mode or you won't know how to get out
of it though. :)

I use M-x term instead of shell mode to interact with git.  That works
fine for me.

C-c C-j and C-c C-k switches between line and character mode so the
regular emacs control sequences are not sent directly to the term
session.

yes that works for me too but I'm wondering why it doesn't for shell mode...

the funny thing is that the following command in emacs' shell actually
do nothing.

$ PAGE=cat git diff HEAD^
$

PAGE?  or PAGER?

PAGER

But I actually know it doesn't print anything, because I put 'HEAD'
instead of 'HEAD^', sorry for the wrong alert.

Can't git make 'cat' the default pager when run on a dumb terminal ?

IIRC, `more` works on a dumb terminal.

But using PAGER=cat is a longstanding and widely used trick
among Emacs old timers, predating the EDITOR=emacsclient, which
is even nicer.  I would highly recommend it.  These two
environment variables make running *everything* in compilation
mode (or shell buffer) so much nicer than otherwise.

yes it does although the behaviour is a bit weird. Not all screen is used.

I think I'm going to give a try PAGER=more and EDITOR=emacsclient
config with shell buffer and see if it can fit well my git usage.

I tried to use term mode but it's pretty annoying to switch between
'line' and 'char' mode all the time.

BTW Junio, just out of curiosity, do you use shell or term mode ?

BTW why not making 'more' the default on a dumb term instead of 'less' ?

Neither.  Almost all of my external command session inside Emacs
is done in compilation mode.  I even bind "C-x c" to "compile".

Which ones do you specifically have in mind to have trouble
with?

well none in peculiar (since I now use PAGER=more), I'm just suprised
you're using compilation mode for all your commands.

It simply avoids this kind of output when running `git-diff` from
shell mode for example:

 ^[[m
 The way you use it is:^[[m
 ^[[m

 $ git bisect start^[[m
-$ git bisect bad                       # Current version is bad^[[m

-                                       # tested that was good^[[m
+$ git bisect bad                 # Current version is bad^[[m
