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.external:: 64 If this config variable is set, diff generation is not 65 performed using the internal diff machinery, but using the 66 given command. Can be overridden with the `GIT_EXTERNAL_DIFF' 67 environment variable. The command is called with parameters 68 as described under "git Diffs" in linkgit:git[1]. Note: if 69 you want to use an external diff program only on a subset of 70 your files, you might want to use linkgit:gitattributes[5] instead. 71 72diff.ignoreSubmodules:: 73 Sets the default value of --ignore-submodules. Note that this 74 affects only 'git diff' Porcelain, and not lower level 'diff' 75 commands such as 'git diff-files'. 'git checkout' also honors 76 this setting when reporting uncommitted changes. Setting it to 77 'all' disables the submodule summary normally shown by 'git commit' 78 and 'git status' when `status.submoduleSummary` is set unless it is 79 overridden by using the --ignore-submodules command-line option. 80 The 'git submodule' commands are not affected by this setting. 81 82diff.mnemonicPrefix:: 83 If set, 'git diff' uses a prefix pair that is different from the 84 standard "a/" and "b/" depending on what is being compared. When 85 this configuration is in effect, reverse diff output also swaps 86 the order of the prefixes: 87`git diff`;; 88 compares the (i)ndex and the (w)ork tree; 89`git diff HEAD`;; 90 compares a (c)ommit and the (w)ork tree; 91`git diff --cached`;; 92 compares a (c)ommit and the (i)ndex; 93`git diff HEAD:file1 file2`;; 94 compares an (o)bject and a (w)ork tree entity; 95`git diff --no-index a b`;; 96 compares two non-git things (1) and (2). 97 98diff.noprefix:: 99 If set, 'git diff' does not show any source or destination prefix. 100 101diff.orderFile:: 102 File indicating how to order files within a diff, using 103 one shell glob pattern per line. 104 If `diff.orderFile` is a relative pathname, it is treated as 105 relative to the top of the working tree. 106 Can be overridden by the '-O' option to linkgit:git-diff[1]. 107 108diff.renameLimit:: 109 The number of files to consider when performing the copy/rename 110 detection; equivalent to the 'git diff' option `-l`. 111 112diff.renames:: 113 Whether and how Git detects renames. If set to "false", 114 rename detection is disabled. If set to "true", basic rename 115 detection is enabled. If set to "copies" or "copy", Git will 116 detect copies, as well. Defaults to true. Note that this 117 affects only 'git diff' Porcelain like linkgit:git-diff[1] and 118 linkgit:git-log[1], and not lower level commands such as 119 linkgit:git-diff-files[1]. 120 121diff.suppressBlankEmpty:: 122 A boolean to inhibit the standard behavior of printing a space 123 before each empty output line. Defaults to false. 124 125diff.submodule:: 126 Specify the format in which differences in submodules are 127 shown. The "short" format just shows the names of the commits 128 at the beginning and end of the range. The "log" format lists 129 the commits in the range like linkgit:git-submodule[1] `summary` 130 does. The "diff" format shows an inline diff of the changed 131 contents of the submodule. Defaults to "short". 132 133diff.wordRegex:: 134 A POSIX Extended Regular Expression used to determine what is a "word" 135 when performing word-by-word difference calculations. Character 136 sequences that match the regular expression are "words", all other 137 characters are *ignorable* whitespace. 138 139diff.<driver>.command:: 140 The custom diff driver command. See linkgit:gitattributes[5] 141 for details. 142 143diff.<driver>.xfuncname:: 144 The regular expression that the diff driver should use to 145 recognize the hunk header. A built-in pattern may also be used. 146 See linkgit:gitattributes[5] for details. 147 148diff.<driver>.binary:: 149 Set this option to true to make the diff driver treat files as 150 binary. See linkgit:gitattributes[5] for details. 151 152diff.<driver>.textconv:: 153 The command that the diff driver should call to generate the 154 text-converted version of a file. The result of the 155 conversion is used to generate a human-readable diff. See 156 linkgit:gitattributes[5] for details. 157 158diff.<driver>.wordRegex:: 159 The regular expression that the diff driver should use to 160 split words in a line. See linkgit:gitattributes[5] for 161 details. 162 163diff.<driver>.cachetextconv:: 164 Set this option to true to make the diff driver cache the text 165 conversion outputs. See linkgit:gitattributes[5] for details. 166 167diff.tool:: 168 Controls which diff tool is used by linkgit:git-difftool[1]. 169 This variable overrides the value configured in `merge.tool`. 170 The list below shows the valid built-in values. 171 Any other value is treated as a custom diff tool and requires 172 that a corresponding difftool.<tool>.cmd variable is defined. 173 174include::mergetools-diff.txt[] 175 176diff.indentHeuristic:: 177diff.compactionHeuristic:: 178 Set one of these options to `true` to enable one of two 179 experimental heuristics that shift diff hunk boundaries to 180 make patches easier to read. 181 182diff.algorithm:: 183 Choose a diff algorithm. The variants are as follows: 184+ 185-- 186`default`, `myers`;; 187 The basic greedy diff algorithm. Currently, this is the default. 188`minimal`;; 189 Spend extra time to make sure the smallest possible diff is 190 produced. 191`patience`;; 192 Use "patience diff" algorithm when generating patches. 193`histogram`;; 194 This algorithm extends the patience algorithm to "support 195 low-occurrence common elements". 196-- 197+ 198 199diff.wsErrorHighlight:: 200 A comma separated list of `old`, `new`, `context`, that 201 specifies how whitespace errors on lines are highlighted 202 with `color.diff.whitespace`. Can be overridden by the 203 command line option `--ws-error-highlight=<kind>`
