This allows users to specify custom low-level merge driver per path, using the attributes mechanism. Just like you can specify one of built-in "text", "binary", "union" low-level merge drivers by saying: * merge=text .gitignore merge=union *.jpg merge=binary pick a name of your favorite merge driver, and assign it as the value of the 'merge' attribute. A custom low-level merge driver is defined via the config mechanism. This patch introduces 'merge.driver', a multi-valued configuration. Its value is the name (i.e. the one you use as the value of 'merge' attribute) followed by a command line specification. The command line can contain %O, %A, and %B to be interpolated with the names of temporary files that hold the common ancestor version, the version from your branch, and the version from the other branch, and the resulting command is spawned. The low-level merge driver is expected to update the temporary file for your branch (i.e. %A) with the result and exit with status 0 for a clean merge, and non-zero status for a conflicted merge. A new test in t6026 demonstrates a sample usage. Signed-off-by: Junio C Hamano <junkio@cox.net>
//////////////////////////////////////////////////////////////// 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/tutorial.txt to get started, then see Documentation/everyday.txt for a useful minimum set of commands, and "man git-commandname" for documentation of each command. CVS users may also want to read Documentation/cvs-migration.txt. Many Git online resources are accessible from http://git.or.cz/ 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.
