DESCRIPTION

|
|
|
Use `git mergetool` to run one of several merge utilities to resolve
|
2010-01-09 23:33:00 +00:00
|
|
|
merge conflicts. It is typically run after 'git merge'.
|
2007-03-06 05:05:16 +00:00
|
|
|
|
|
|
|
If one or more <file> parameters are given, the merge tool program will
|
2011-09-16 02:12:10 +00:00
|
|
|
be run to resolve differences on each file (skipping those without
|
|
|
|
conflicts). Specifying a directory will include all unresolved files in
|
|
|
|
that path. If no <file> names are specified, 'git mergetool' will run
|
|
|
|
the merge tool program on every file with merge conflicts.

OPTIONS

-------

|
|
|
-t <tool>::
|
|
|
|
--tool=<tool>::
|
2007-03-06 05:05:16 +00:00
|
|
|
Use the merge resolution program specified by <tool>.
|
2012-07-23 21:16:12 +00:00
|
|
|
Valid values include emerge, gvimdiff, kdiff3,
|
|
|
|
meld, vimdiff, and tortoisemerge. Run `git mergetool --tool-help`
|
|
|
|
for the list of valid <tool> settings.

|
|
|
If a merge resolution program is not specified, 'git mergetool'
|
2008-03-08 20:46:34 +00:00
|
|
|
will use the configuration variable `merge.tool`. If the
|
2010-01-09 23:33:00 +00:00
|
|
|
configuration variable `merge.tool` is not set, 'git mergetool'
|
2007-03-27 15:38:59 +00:00
|
|
|
will pick a suitable default.
|
2007-10-17 17:16:11 +00:00
|
|
|
+
|
|
|
|
You can explicitly provide a full path to the tool by setting the
|
2008-03-08 20:46:34 +00:00
|
|
|
configuration variable `mergetool.<tool>.path`. For example, you
|
2007-10-17 17:16:11 +00:00
|
|
|
can configure the absolute path to kdiff3 by setting
|
2010-01-09 23:33:00 +00:00
|
|
|
`mergetool.kdiff3.path`. Otherwise, 'git mergetool' assumes the
|
2008-03-08 20:46:34 +00:00
|
|
|
tool is available in PATH.
|
2008-03-08 20:47:06 +00:00
|
|
|
+
|
2008-12-09 06:23:51 +00:00
|
|
|
Instead of running one of the known merge tool programs,
|
2010-01-09 23:33:00 +00:00
|
|
|
'git mergetool' can be customized to run an alternative program
|
2008-08-05 16:12:05 +00:00
|
|
|
by specifying the command line to invoke in a configuration
|
2008-03-08 20:47:06 +00:00
|
|
|
variable `mergetool.<tool>.cmd`.
|
|
|
|
+
|
2010-01-09 23:33:00 +00:00
|
|
|
When 'git mergetool' is invoked with this tool (either through the
|
2008-03-08 20:47:06 +00:00
|
|
|
`-t` or `--tool` option or the `merge.tool` configuration
|
|
|
|
variable) the configured command line will be invoked with `$BASE`
|
|
|
|
set to the name of a temporary file containing the common base for
|
|
|
|
the merge, if available; `$LOCAL` set to the name of a temporary
|
|
|
|
file containing the contents of the file on the current branch;
|
|
|
|
`$REMOTE` set to the name of a temporary file containing the
|
|
|
|
contents of the file to be merged, and `$MERGED` set to the name
|
|
|
|
of the file to which the merge tool should write the result of the
|
|
|
|
merge resolution.
|
|
|
|
+
|
|
|
|
If the custom merge tool correctly indicates the success of a
|
2008-12-09 06:23:51 +00:00
|
|
|
merge resolution with its exit code, then the configuration
|
2008-03-08 20:47:06 +00:00
|
|
|
variable `mergetool.<tool>.trustExitCode` can be set to `true`.
|
2010-01-09 23:33:00 +00:00
|
|
|
Otherwise, 'git mergetool' will prompt the user to indicate the
|
2008-03-08 20:47:06 +00:00
|
|
|
success of the resolution after the custom tool has exited.
|
2007-03-06 05:05:16 +00:00

|
-y::
|
|
|
|
--no-prompt::
|
2008-11-13 12:41:14 +00:00
|
|
|
Don't prompt before each invocation of the merge resolution
|
|
|
|
program.
|
|
|
|
|
|
|
|
--prompt::
|
|
|
|
Prompt before each invocation of the merge resolution program.
|
|
|
|
This is the default behaviour; the option is provided to
|
|
|
|
override any configuration settings.

TEMPORARY FILES
|
|
|
|
---------------
|
|
|
|
`git mergetool` creates `*.orig` backup files while resolving merges.
|
|
|
|
These are safe to remove once a file has been merged and its
|
|
|
|
`git mergetool` session has completed.
|
|
|
|
|
|
|
|
Setting the `mergetool.keepBackup` configuration variable to `false`
|
|
|
|
causes `git mergetool` to automatically remove the backup as files
|
|
|
|
are successfully merged.
