SZEDER Gábor c63437cbd7 bash: improve aliased command recognition To support completion for aliases, the completion script tries to figure out which git command is invoked by an alias. Its implementation in __git_aliased_command() is rather straightforward: it returns the first word from the alias. For simple aliases starting with the git command (e.g. alias.last = cat-file commit HEAD) this gives the right results. Unfortunately, it does not work with shell command aliases, which can get rather complex, as illustrated by one of Junio's aliases: [alias] lgm = "!sh -c 'GIT_NOTES_REF=refs/notes/amlog git log \"$@\" \|\| :' -" In this case the current implementation returns "!sh" as the aliased git command, which is obviosly wrong. The full parsing of a shell command alias like that in the completion code is clearly unfeasible. However, we can easily improve on aliased command recognition by eleminating stuff that is definitely not a git command: shell commands (anything starting with '!'), command line options (anything starting with '-'), environment variables (anything with a '=' in it), and git itself. This way the above alias would be handled correctly, and the completion script would correctly recognize "log" as the aliased git command. Of course, this solution is not perfect either, and could be fooled easily. It's not hard to construct an alias, in which a word does not match any of these filter patterns, but is still not a git command (e.g. by setting an environment variable to a value which contains spaces). It may even return false positives, when the output of a git command is piped into an other git command, and the second gets the command line options via $@, but options for the first one are offered. However, the following patches will enable the user to supply custom completion scripts for aliases, which can be used to remedy these problematic cases.

////////////////////////////////////////////////////////////////

	GIT - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, depending on your mood.

 - random three-letter combination that is pronounceable, and not
   actually used by any common UNIX command.  The fact that it is a
   mispronunciation of "get" may or may not be relevant.
 - stupid. contemptible and despicable. simple. Take your pick from the
   dictionary of slang.
 - "global information tracker": you're in a good mood, and it actually
   works for you. Angels sing, and a light suddenly fills the room.
 - "goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.

Please read the file INSTALL for installation instructions.

See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".

CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).

Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.

The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org. To subscribe
to the list, send an email with just "subscribe git" in the body to
majordomo@vger.kernel.org. The mailing list archives are available at
http://marc.theaimsgroup.com/?l=git and other archival sites.

The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
