Include the "config/difftool.txt" file in "git-difftool.txt", and move the relevant part of git-difftool(1) configuration from "config/diff.txt" to config/difftool.txt". Doing this is slightly odd, as we usually discuss configuration in alphabetical order, but by doing it we're able to include the full set of configuration used by git-difftool(1) (and only that configuration) in its own documentation.

git-difftool - Show changes using common diff tools
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'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
|
|
-------
|
|
-d::
|
|
--dir-diff::
|
|
Copy the modified files to a temporary location and perform
|
|
a directory diff on them. This mode never prompts before
|
|
launching the diff tool.
|
|
|
|
-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.
|
|
|
|
--rotate-to=<file>::
|
|
Start showing the diff for the given path,
|
|
the paths before it will move to end and output.
|
|
|
|
--skip-to=<file>::
|
|
Start showing the diff for the given path, skipping all
|
|
the paths before it.
|
|
|
|
-t <tool>::
|
|
--tool=<tool>::
|
|
Use the diff tool specified by <tool>. Valid values include
|
|
emerge, kompare, meld, and vimdiff. Run `git difftool --tool-help`
|
|
for the list of valid <tool> settings.
|
|
+
|
|
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 `$MERGED`.
|
|
|
|
--tool-help::
|
|
Print a list of diff tools that may be used with `--tool`.
|
|
|
|
--[no-]symlinks::
|
|
'git difftool''s default behavior is create symlinks to the
|
|
working tree when run in `--dir-diff` mode and the right-hand
|
|
side of the comparison yields the same content as the file in
|
|
the working tree.
|
|
+
|
|
Specifying `--no-symlinks` instructs 'git difftool' to create copies
|
|
instead. `--no-symlinks` is the default on Windows.
|
|
|
|
-x <command>::
|
|
--extcmd=<command>::
|
|
Specify a custom command for viewing diffs.
|
|
'git-difftool' ignores the configured defaults and runs
|
|
`$command $LOCAL $REMOTE` when this option is specified.
|
|
Additionally, `$BASE` is set in the environment.
|
|
|
|
-g::
|
|
--[no-]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`. The `--no-gui`
|
|
option can be used to override this setting. If `diff.guitool`
|
|
is not set, we will fallback in the order of `merge.guitool`,
|
|
`diff.tool`, `merge.tool` until a tool is found.
|
|
|
|
--[no-]trust-exit-code::
|
|
'git-difftool' invokes a diff tool individually on each file.
|
|
Errors reported by the diff tool are ignored by default.
|
|
Use `--trust-exit-code` to make 'git-difftool' exit when an
|
|
invoked diff tool returns a non-zero exit code.
|
|
+
|
|
'git-difftool' will forward the exit code of the invoked tool when
|
|
`--trust-exit-code` is used.
|
|
|
|
See linkgit:git-diff[1] for the full list of supported options.
|
|
|
|
CONFIGURATION
|
|
-------------
