1diff.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'. 10 11diff.dirstat:: 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: 18+ 19-- 20`changes`;; 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. 26`lines`;; 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. 34`files`;; 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. 39`cumulative`;; 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. 44<limit>;; 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. 48-- 49+ 50Example: The following will count changed files, while ignoring 51directories with less than 10% of the total amount of changed files, 52and accumulating child directory counts in the parent directories: 53`files,10,cumulative`. 54 55diff.statGraphWidth:: 56 Limit the width of the graph part in --stat output. If set, applies 57 to all commands generating --stat output except format-patch. 58 59diff.context:: 60 Generate diffs with <n> lines of context instead of the default 61 of 3. This value is overridden by the -U option. 62 63diff.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` 67 command line option. 68 69diff.external:: 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. 77 78diff.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. 87 88diff.mnemonicPrefix:: 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: 93`git diff`;; 94 compares the (i)ndex and the (w)ork tree; 95`git diff HEAD`;; 96 compares a (c)ommit and the (w)ork tree; 97`git diff --cached`;; 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). 103 104diff.noprefix:: 105 If set, 'git diff' does not show any source or destination prefix. 106 107diff.orderFile:: 108 File indicating how to order files within a diff. 109 See the '-O' option to linkgit:git-diff[1] for details. 110 If `diff.orderFile` is a relative pathname, it is treated as 111 relative to the top of the working tree. 112 113diff.renameLimit:: 114 The number of files to consider when performing the copy/rename 115 detection; equivalent to the 'git diff' option `-l`. This setting 116 has no effect if rename detection is turned off. 117 118diff.renames:: 119 Whether and how Git detects renames. If set to "false", 120 rename detection is disabled. If set to "true", basic rename 121 detection is enabled. If set to "copies" or "copy", Git will 122 detect copies, as well. Defaults to true. Note that this 123 affects only 'git diff' Porcelain like linkgit:git-diff[1] and 124 linkgit:git-log[1], and not lower level commands such as 125 linkgit:git-diff-files[1]. 126 127diff.suppressBlankEmpty:: 128 A boolean to inhibit the standard behavior of printing a space 129 before each empty output line. Defaults to false. 130 131diff.submodule:: 132 Specify the format in which differences in submodules are 133 shown. The "short" format just shows the names of the commits 134 at the beginning and end of the range. The "log" format lists 135 the commits in the range like linkgit:git-submodule[1] `summary` 136 does. The "diff" format shows an inline diff of the changed 137 contents of the submodule. Defaults to "short". 138 139diff.wordRegex:: 140 A POSIX Extended Regular Expression used to determine what is a "word" 141 when performing word-by-word difference calculations. Character 142 sequences that match the regular expression are "words", all other 143 characters are *ignorable* whitespace. 144 145diff.<driver>.command:: 146 The custom diff driver command. See linkgit:gitattributes[5] 147 for details. 148 149diff.<driver>.xfuncname:: 150 The regular expression that the diff driver should use to 151 recognize the hunk header. A built-in pattern may also be used. 152 See linkgit:gitattributes[5] for details. 153 154diff.<driver>.binary:: 155 Set this option to true to make the diff driver treat files as 156 binary. See linkgit:gitattributes[5] for details. 157 158diff.<driver>.textconv:: 159 The command that the diff driver should call to generate the 160 text-converted version of a file. The result of the 161 conversion is used to generate a human-readable diff. See 162 linkgit:gitattributes[5] for details. 163 164diff.<driver>.wordRegex:: 165 The regular expression that the diff driver should use to 166 split words in a line. See linkgit:gitattributes[5] for 167 details. 168 169diff.<driver>.cachetextconv:: 170 Set this option to true to make the diff driver cache the text 171 conversion outputs. See linkgit:gitattributes[5] for details. 172 173diff.tool:: 174 Controls which diff tool is used by linkgit:git-difftool[1]. 175 This variable overrides the value configured in `merge.tool`. 176 The list below shows the valid built-in values. 177 Any other value is treated as a custom diff tool and requires 178 that a corresponding difftool.<tool>.cmd variable is defined. 179 180include::mergetools-diff.txt[] 181 182diff.indentHeuristic:: 183 Set this option to `true` to enable experimental heuristics 184 that shift diff hunk boundaries to make patches easier to read. 185 186diff.algorithm:: 187 Choose a diff algorithm. The variants are as follows: 188+ 189-- 190`default`, `myers`;; 191 The basic greedy diff algorithm. Currently, this is the default. 192`minimal`;; 193 Spend extra time to make sure the smallest possible diff is 194 produced. 195`patience`;; 196 Use "patience diff" algorithm when generating patches. 197`histogram`;; 198 This algorithm extends the patience algorithm to "support 199 low-occurrence common elements". 200-- 201+ 202 203diff.wsErrorHighlight:: 204 Highlight whitespace errors in the `context`, `old` or `new` 205 lines of the diff. Multiple values are separated by comma, 206 `none` resets previous values, `default` reset the list to 207 `new` and `all` is a shorthand for `old,new,context`. The 208 whitespace errors are colored with `color.diff.whitespace`. 209 The command line option `--ws-error-highlight=<kind>` 210 overrides this setting.
