1 diff.autoRefreshIndex::
2 When using 'git diff' to compare with work tree
3 files, do not consider stat-only change as changed.
4 Instead, silently run `git update-index --refresh` to
5 update the cached stat information for paths whose
6 contents in the work tree match the contents in the
7 index. This option defaults to true. Note that this
8 affects only 'git diff' Porcelain, and not lower level
9 'diff' commands such as 'git diff-files'.
12 A comma separated list of `--dirstat` parameters specifying the
13 default behavior of the `--dirstat` option to linkgit:git-diff[1]`
14 and friends. The defaults can be overridden on the command line
15 (using `--dirstat=<param1,param2,...>`). The fallback defaults
16 (when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
17 The following parameters are available:
21 Compute the dirstat numbers by counting the lines that have been
22 removed from the source, or added to the destination. This ignores
23 the amount of pure code movements within a file. In other words,
24 rearranging lines in a file is not counted as much as other changes.
25 This is the default behavior when no parameter is given.
27 Compute the dirstat numbers by doing the regular line-based diff
28 analysis, and summing the removed/added line counts. (For binary
29 files, count 64-byte chunks instead, since binary files have no
30 natural concept of lines). This is a more expensive `--dirstat`
31 behavior than the `changes` behavior, but it does count rearranged
32 lines within a file as much as other changes. The resulting output
33 is consistent with what you get from the other `--*stat` options.
35 Compute the dirstat numbers by counting the number of files changed.
36 Each changed file counts equally in the dirstat analysis. This is
37 the computationally cheapest `--dirstat` behavior, since it does
38 not have to look at the file contents at all.
40 Count changes in a child directory for the parent directory as well.
41 Note that when using `cumulative`, the sum of the percentages
42 reported may exceed 100%. The default (non-cumulative) behavior can
43 be specified with the `noncumulative` parameter.
45 An integer parameter specifies a cut-off percent (3% by default).
46 Directories contributing less than this percentage of the changes
47 are not shown in the output.
50 Example: The following will count changed files, while ignoring
51 directories with less than 10% of the total amount of changed files,
52 and accumulating child directory counts in the parent directories:
53 `files,10,cumulative`.
56 Limit the width of the graph part in --stat output. If set, applies
57 to all commands generating --stat output except format-patch.
60 Generate diffs with <n> lines of context instead of the default
61 of 3. This value is overridden by the -U option.
63 diff.interHunkContext::
64 Show the context between diff hunks, up to the specified number
65 of lines, thereby fusing the hunks that are close to each other.
66 This value serves as the default for the `--inter-hunk-context`
70 If this config variable is set, diff generation is not
71 performed using the internal diff machinery, but using the
72 given command. Can be overridden with the `GIT_EXTERNAL_DIFF'
73 environment variable. The command is called with parameters
74 as described under "git Diffs" in linkgit:git[1]. Note: if
75 you want to use an external diff program only on a subset of
76 your files, you might want to use linkgit:gitattributes[5] instead.
78 diff.ignoreSubmodules::
79 Sets the default value of --ignore-submodules. Note that this
80 affects only 'git diff' Porcelain, and not lower level 'diff'
81 commands such as 'git diff-files'. 'git checkout' also honors
82 this setting when reporting uncommitted changes. Setting it to
83 'all' disables the submodule summary normally shown by 'git commit'
84 and 'git status' when `status.submoduleSummary` is set unless it is
85 overridden by using the --ignore-submodules command-line option.
86 The 'git submodule' commands are not affected by this setting.
89 If set, 'git diff' uses a prefix pair that is different from the
90 standard "a/" and "b/" depending on what is being compared. When
91 this configuration is in effect, reverse diff output also swaps
92 the order of the prefixes:
94 compares the (i)ndex and the (w)ork tree;
96 compares a (c)ommit and the (w)ork tree;
98 compares a (c)ommit and the (i)ndex;
99 `git diff HEAD:file1 file2`;;
100 compares an (o)bject and a (w)ork tree entity;
101 `git diff --no-index a b`;;
102 compares two non-git things (1) and (2).
105 If set, 'git diff' does not show any source or destination prefix.
108 File indicating how to order files within a diff, using
109 one shell glob pattern per line.
110 Can be overridden by the '-O' option to linkgit:git-diff[1].
113 The number of files to consider when performing the copy/rename
114 detection; equivalent to the 'git diff' option `-l`.
117 Whether and how Git detects renames. If set to "false",
118 rename detection is disabled. If set to "true", basic rename
119 detection is enabled. If set to "copies" or "copy", Git will
120 detect copies, as well. Defaults to true. Note that this
121 affects only 'git diff' Porcelain like linkgit:git-diff[1] and
122 linkgit:git-log[1], and not lower level commands such as
123 linkgit:git-diff-files[1].
125 diff.suppressBlankEmpty::
126 A boolean to inhibit the standard behavior of printing a space
127 before each empty output line. Defaults to false.
130 Specify the format in which differences in submodules are
131 shown. The "short" format just shows the names of the commits
132 at the beginning and end of the range. The "log" format lists
133 the commits in the range like linkgit:git-submodule[1] `summary`
134 does. The "diff" format shows an inline diff of the changed
135 contents of the submodule. Defaults to "short".
138 A POSIX Extended Regular Expression used to determine what is a "word"
139 when performing word-by-word difference calculations. Character
140 sequences that match the regular expression are "words", all other
141 characters are *ignorable* whitespace.
143 diff.<driver>.command::
144 The custom diff driver command. See linkgit:gitattributes[5]
147 diff.<driver>.xfuncname::
148 The regular expression that the diff driver should use to
149 recognize the hunk header. A built-in pattern may also be used.
150 See linkgit:gitattributes[5] for details.
152 diff.<driver>.binary::
153 Set this option to true to make the diff driver treat files as
154 binary. See linkgit:gitattributes[5] for details.
156 diff.<driver>.textconv::
157 The command that the diff driver should call to generate the
158 text-converted version of a file. The result of the
159 conversion is used to generate a human-readable diff. See
160 linkgit:gitattributes[5] for details.
162 diff.<driver>.wordRegex::
163 The regular expression that the diff driver should use to
164 split words in a line. See linkgit:gitattributes[5] for
167 diff.<driver>.cachetextconv::
168 Set this option to true to make the diff driver cache the text
169 conversion outputs. See linkgit:gitattributes[5] for details.
172 Controls which diff tool is used by linkgit:git-difftool[1].
173 This variable overrides the value configured in `merge.tool`.
174 The list below shows the valid built-in values.
175 Any other value is treated as a custom diff tool and requires
176 that a corresponding difftool.<tool>.cmd variable is defined.
178 include::mergetools-diff.txt[]
180 diff.indentHeuristic::
181 Set this option to `true` to enable experimental heuristics
182 that shift diff hunk boundaries to make patches easier to read.
185 Choose a diff algorithm. The variants are as follows:
189 The basic greedy diff algorithm. Currently, this is the default.
191 Spend extra time to make sure the smallest possible diff is
194 Use "patience diff" algorithm when generating patches.
196 This algorithm extends the patience algorithm to "support
197 low-occurrence common elements".
201 diff.wsErrorHighlight::
202 A comma separated list of `old`, `new`, `context`, that
203 specifies how whitespace errors on lines are highlighted
204 with `color.diff.whitespace`. Can be overridden by the
205 command line option `--ws-error-highlight=<kind>`
