NAME |
|
---- |
|
git-difftool - Show changes using common diff tools |
|
|
|
SYNOPSIS |
|
-------- |
|
'git difftool' [<options>] [<commit> [<commit>]] [--] [<path>...] |
|
|
|
DESCRIPTION |
|
----------- |
|
'git difftool' is a git command that allows you to compare and edit files |
|
between revisions using common diff tools. 'git difftool' is a frontend |
|
to 'git diff' and accepts the same options and arguments. See |
|
linkgit:git-diff[1]. |
|
|
|
OPTIONS |
|
------- |
|
-y:: |
|
--no-prompt:: |
|
Do not prompt before launching a diff tool. |
|
|
|
--prompt:: |
|
Prompt before each invocation of the diff tool. |
|
This is the default behaviour; the option is provided to |
|
override any configuration settings. |
|
|
|
-t <tool>:: |
|
--tool=<tool>:: |
|
Use the diff tool specified by <tool>. |
|
Valid merge tools are: |
|
araxis, bc3, diffuse, emerge, ecmerge, gvimdiff, kdiff3, |
|
kompare, meld, opendiff, p4merge, tkdiff, vimdiff and xxdiff. |
|
+ |
|
If a diff tool is not specified, 'git difftool' |
|
will use the configuration variable `diff.tool`. If the |
|
configuration variable `diff.tool` is not set, 'git difftool' |
|
will pick a suitable default. |
|
+ |
|
You can explicitly provide a full path to the tool by setting the |
|
configuration variable `difftool.<tool>.path`. For example, you |
|
can configure the absolute path to kdiff3 by setting |
|
`difftool.kdiff3.path`. Otherwise, 'git difftool' assumes the |
|
tool is available in PATH. |
|
+ |
|
Instead of running one of the known diff tools, |
|
'git difftool' can be customized to run an alternative program |
|
by specifying the command line to invoke in a configuration |
|
variable `difftool.<tool>.cmd`. |
|
+ |
|
When 'git difftool' is invoked with this tool (either through the |
|
`-t` or `--tool` option or the `diff.tool` configuration variable) |
|
the configured command line will be invoked with the following |
|
variables available: `$LOCAL` is set to the name of the temporary |
|
file containing the contents of the diff pre-image and `$REMOTE` |
|
is set to the name of the temporary file containing the contents |
|
of the diff post-image. `$MERGED` is the name of the file which is |
|
being compared. `$BASE` is provided for compatibility |
|
with custom merge tool commands and has the same value as `$MERGED`. |
|
|
|
-x <command>:: |
|
--extcmd=<command>:: |
|
Specify a custom command for viewing diffs. |
|
'git-difftool' ignores the configured defaults and runs |
|
`$command $LOCAL $REMOTE` when this option is specified. |
|
Additionally, `$BASE` is set in the environment. |
|
|
|
-g:: |
|
--gui:: |
|
When 'git-difftool' is invoked with the `-g` or `--gui` option |
|
the default diff tool will be read from the configured |
|
`diff.guitool` variable instead of `diff.tool`. |
|
|
|
See linkgit:git-diff[1] for the full list of supported options. |
|
|
|
CONFIG VARIABLES |
|
---------------- |
|
'git difftool' falls back to 'git mergetool' config variables when the |
|
difftool equivalents have not been defined. |
|
|
|
diff.tool:: |
|
The default diff tool to use. |
|
|
|
diff.guitool:: |
|
The default diff tool to use when `--gui` is specified. |
|
|
|
difftool.<tool>.path:: |
|
Override the path for the given tool. This is useful in case |
|
your tool is not in the PATH. |
|
|
|
difftool.<tool>.cmd:: |
|
Specify the command to invoke the specified diff tool. |
|
+ |
|
See the `--tool=<tool>` option above for more details. |
|
|
|
difftool.prompt:: |
|
Prompt before each invocation of the diff tool. |
|
