diff.autorefreshindex::
|
|
When using 'git diff' to compare with work tree
|
|
files, do not consider stat-only change as changed.
|
|
Instead, silently run `git update-index --refresh` to
|
|
update the cached stat information for paths whose
|
|
contents in the work tree match the contents in the
|
|
index. This option defaults to true. Note that this
|
|
affects only 'git diff' Porcelain, and not lower level
|
|
'diff' commands such as 'git diff-files'.
|
|
|
|
diff.dirstat::
|
|
A comma separated list of `--dirstat` parameters specifying the
|
|
default behavior of the `--dirstat` option to linkgit:git-diff[1]`
|
|
and friends. The defaults can be overridden on the command line
|
|
(using `--dirstat=<param1,param2,...>`). The fallback defaults
|
|
(when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
|
|
The following parameters are available:
|
|
+
|
|
--
|
|
`changes`;;
|
|
Compute the dirstat numbers by counting the lines that have been
|
|
removed from the source, or added to the destination. This ignores
|
|
the amount of pure code movements within a file. In other words,
|
|
rearranging lines in a file is not counted as much as other changes.
|
|
This is the default behavior when no parameter is given.
|
|
`lines`;;
|
|
Compute the dirstat numbers by doing the regular line-based diff
|
|
analysis, and summing the removed/added line counts. (For binary
|
|
files, count 64-byte chunks instead, since binary files have no
|
|
natural concept of lines). This is a more expensive `--dirstat`
|
|
behavior than the `changes` behavior, but it does count rearranged
|
|
lines within a file as much as other changes. The resulting output
|
|
is consistent with what you get from the other `--*stat` options.
|
|
`files`;;
|
|
Compute the dirstat numbers by counting the number of files changed.
|
|
Each changed file counts equally in the dirstat analysis. This is
|
|
the computationally cheapest `--dirstat` behavior, since it does
|
|
not have to look at the file contents at all.
|
|
`cumulative`;;
|
|
Count changes in a child directory for the parent directory as well.
|
|
Note that when using `cumulative`, the sum of the percentages
|
|
reported may exceed 100%. The default (non-cumulative) behavior can
|
|
be specified with the `noncumulative` parameter.
|
|
<limit>;;
|
|
An integer parameter specifies a cut-off percent (3% by default).
|
|
Directories contributing less than this percentage of the changes
|
|
are not shown in the output.
|
|
--
|
|
+
|
|
Example: The following will count changed files, while ignoring
|
|
directories with less than 10% of the total amount of changed files,
|
|
and accumulating child directory counts in the parent directories:
|
|
`files,10,cumulative`.
|
|
|
|
diff.statGraphWidth::
|
|
Limit the width of the graph part in --stat output. If set, applies
|
|
to all commands generating --stat output except format-patch.
|
|
|
|
diff.context::
|
|
Generate diffs with <n> lines of context instead of the default
|
|
of 3. This value is overridden by the -U option.
|
|
|
|
diff.external::
|
|
If this config variable is set, diff generation is not
|
|
performed using the internal diff machinery, but using the
|
|
given command. Can be overridden with the `GIT_EXTERNAL_DIFF'
|
|
environment variable. The command is called with parameters
|
|
as described under "git Diffs" in linkgit:git[1]. Note: if
|
|
you want to use an external diff program only on a subset of
|
|
your files, you might want to use linkgit:gitattributes[5] instead.
|
|
|
|
diff.ignoreSubmodules::
|
|
Sets the default value of --ignore-submodules. Note that this
|
|
affects only 'git diff' Porcelain, and not lower level 'diff'
|
|
commands such as 'git diff-files'. 'git checkout' also honors
|
|
this setting when reporting uncommitted changes.
|
|
|
|
diff.mnemonicprefix::
|
|
If set, 'git diff' uses a prefix pair that is different from the
|
|
standard "a/" and "b/" depending on what is being compared. When
|
|
this configuration is in effect, reverse diff output also swaps
|
|
the order of the prefixes:
|
|
`git diff`;;
|
|
compares the (i)ndex and the (w)ork tree;
|
|
`git diff HEAD`;;
|
|
compares a (c)ommit and the (w)ork tree;
|
|
`git diff --cached`;;
|
|
compares a (c)ommit and the (i)ndex;
|
|
`git diff HEAD:file1 file2`;;
|
|
compares an (o)bject and a (w)ork tree entity;
|
|
`git diff --no-index a b`;;
|
|
compares two non-git things (1) and (2).
|
|
|
|
diff.noprefix::
|
|
If set, 'git diff' does not show any source or destination prefix.
|
|
|
|
diff.renameLimit::
|
|
The number of files to consider when performing the copy/rename
|
|
detection; equivalent to the 'git diff' option '-l'.
|
|
|
|
diff.renames::
|
|
Tells Git to detect renames. If set to any boolean value, it
|
|
will enable basic rename detection. If set to "copies" or
|
|
"copy", it will detect copies, as well.
|
|
|
|
diff.suppressBlankEmpty::
|
|
A boolean to inhibit the standard behavior of printing a space
|
|
before each empty output line. Defaults to false.
|
|
|
|
diff.submodule::
|
|
Specify the format in which differences in submodules are
|
|
shown. The "log" format lists the commits in the range like
|
|
linkgit:git-submodule[1] `summary` does. The "short" format
|
|
format just shows the names of the commits at the beginning
|
|
and end of the range. Defaults to short.
|
|
|
|
diff.wordRegex::
|
|
A POSIX Extended Regular Expression used to determine what is a "word"
|
|
when performing word-by-word difference calculations. Character
|
|
sequences that match the regular expression are "words", all other
|
|
characters are *ignorable* whitespace.
|
|
|
|
diff.<driver>.command::
|
|
The custom diff driver command. See linkgit:gitattributes[5]
|
|
for details.
|
|
|
|
diff.<driver>.xfuncname::
|
|
The regular expression that the diff driver should use to
|
|
recognize the hunk header. A built-in pattern may also be used.
|
|
See linkgit:gitattributes[5] for details.
|
|
|
|
diff.<driver>.binary::
|
|
Set this option to true to make the diff driver treat files as
|
|
binary. See linkgit:gitattributes[5] for details.
|
|
|
|
diff.<driver>.textconv::
|
|
The command that the diff driver should call to generate the
|
|
text-converted version of a file. The result of the
|
|
conversion is used to generate a human-readable diff. See
|
|
linkgit:gitattributes[5] for details.
|
|
|
|
diff.<driver>.wordregex::
|
|
The regular expression that the diff driver should use to
|
|
split words in a line. See linkgit:gitattributes[5] for
|
|
details.
|
|
|
|
diff.<driver>.cachetextconv::
|
|
Set this option to true to make the diff driver cache the text
|
|
conversion outputs. See linkgit:gitattributes[5] for details.
|
|
|
|
diff.tool::
|
|
Controls which diff tool is used by linkgit:git-difftool[1].
|
|
This variable overrides the value configured in `merge.tool`.
|
|
The list below shows the valid built-in values.
|
|
Any other value is treated as a custom diff tool and requires
|
|
that a corresponding difftool.<tool>.cmd variable is defined.
