In git-difftool, if the tool is called with --gui but `diff.guitool` is not set, it falls back to `diff.tool`. Make git-mergetool also fallback from `merge.guitool` to `merge.tool` if the former is undefined. If git-difftool, when called with `--gui`, were to use `get_configured_mergetool` in a future patch, it would also get the fallback behavior in the following precedence: 1. diff.guitool 2. merge.guitool 3. diff.tool 4. merge.tool The behavior for when difftool or mergetool are called without `--gui` should be identical with or without this patch. Note that the search loop could be written as sections="merge" keys="tool" if diff_mode then sections="diff $sections" fi if gui_mode then keys="guitool $keys" fi merge_tool=$( IFS=' ' for key in $keys do for section in $sections do selected=$(git config $section.$key) if test -n "$selected" then echo "$selected" return fi done done) which would make adding a mode in the future much easier. However, adding a new mode will likely never happen as it is highly discouraged so, as a result, it is written in its current form so that it is more readable for future readers.

NAME

----
|
|
git-mergetool - Run merge conflict resolution tools to resolve merge conflicts
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git mergetool' [--tool=<tool>] [-y | --[no-]prompt] [<file>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
Use `git mergetool` to run one of several merge utilities to resolve
|
|
merge conflicts. It is typically run after 'git merge'.
|
|
|
|
If one or more <file> parameters are given, the merge tool program will
|
|
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>::
|
|
Use the merge resolution program specified by <tool>.
|
|
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'
|
|
will use the configuration variable `merge.tool`. If the
|
|
configuration variable `merge.tool` is not set, 'git mergetool'
|
|
will pick a suitable default.
|
|
+
|
|
You can explicitly provide a full path to the tool by setting the
|
|
configuration variable `mergetool.<tool>.path`. For example, you
|
|
can configure the absolute path to kdiff3 by setting
|
|
`mergetool.kdiff3.path`. Otherwise, 'git mergetool' assumes the
|
|
tool is available in PATH.
|
|
+
|
|
Instead of running one of the known merge tool programs,
|
|
'git mergetool' can be customized to run an alternative program
|
|
by specifying the command line to invoke in a configuration
|
|
variable `mergetool.<tool>.cmd`.
|
|
+
|
|
When 'git mergetool' is invoked with this tool (either through the
|
|
`-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
|
|
merge resolution with its exit code, then the configuration
|
|
variable `mergetool.<tool>.trustExitCode` can be set to `true`.
|
|
Otherwise, 'git mergetool' will prompt the user to indicate the
|
|
success of the resolution after the custom tool has exited.
|
|
|
|
--tool-help::
|
|
Print a list of merge tools that may be used with `--tool`.
|
|
|
|
-y::
|
|
--no-prompt::
|
|
Don't prompt before each invocation of the merge resolution
|
|
program.
|
|
This is the default if the merge resolution program is
|
|
explicitly specified with the `--tool` option or with the
|
|
`merge.tool` configuration variable.
|
|
|
|
--prompt::
|
|
Prompt before each invocation of the merge resolution program
|
|
to give the user a chance to skip the path.
|
|
|
|
-g::
|
|
--gui::
|
|
When 'git-mergetool' is invoked with the `-g` or `--gui` option
|
|
the default merge tool will be read from the configured
|
|
`merge.guitool` variable instead of `merge.tool`. If
|
|
`merge.guitool` is not set, we will fallback to the tool
|
|
configured under `merge.tool`.
|
|
|
|
--no-gui::
|
|
This overrides a previous `-g` or `--gui` setting and reads the
|
|
default merge tool will be read from the configured `merge.tool`
|
|
variable.
|
|
|
|
-O<orderfile>::
|
|
Process files in the order specified in the
|
|
<orderfile>, which has one shell glob pattern per line.
|
|
This overrides the `diff.orderFile` configuration variable
|
|
(see linkgit:git-config[1]). To cancel `diff.orderFile`,
|
|
use `-O/dev/null`.
|
|
|
|
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.
