   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'.

  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.external::
  56        If this config variable is set, diff generation is not
  57        performed using the internal diff machinery, but using the
  58        given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
  59        environment variable.  The command is called with parameters
  60        as described under "git Diffs" in linkgit:git[1].  Note: if
  61        you want to use an external diff program only on a subset of
  62        your files, you might want to use linkgit:gitattributes[5] instead.
  63
  64diff.ignoreSubmodules::
  65        Sets the default value of --ignore-submodules. Note that this
  66        affects only 'git diff' Porcelain, and not lower level 'diff'
  67        commands such as 'git diff-files'. 'git checkout' also honors
  68        this setting when reporting uncommitted changes.
  69
  70diff.mnemonicprefix::
  71        If set, 'git diff' uses a prefix pair that is different from the
  72        standard "a/" and "b/" depending on what is being compared.  When
  73        this configuration is in effect, reverse diff output also swaps
  74        the order of the prefixes:
  75`git diff`;;
  76        compares the (i)ndex and the (w)ork tree;
  77`git diff HEAD`;;
  78         compares a (c)ommit and the (w)ork tree;
  79`git diff --cached`;;
  80        compares a (c)ommit and the (i)ndex;
  81`git diff HEAD:file1 file2`;;
  82        compares an (o)bject and a (w)ork tree entity;
  83`git diff --no-index a b`;;
  84        compares two non-git things (1) and (2).
  85
  86diff.noprefix::
  87        If set, 'git diff' does not show any source or destination prefix.
  88
  89diff.renameLimit::
  90        The number of files to consider when performing the copy/rename
  91        detection; equivalent to the 'git diff' option '-l'.
  92
  93diff.renames::
  94        Tells git to detect renames.  If set to any boolean value, it
  95        will enable basic rename detection.  If set to "copies" or
  96        "copy", it will detect copies, as well.
  97
  98diff.suppressBlankEmpty::
  99        A boolean to inhibit the standard behavior of printing a space
 100        before each empty output line. Defaults to false.
 101
 102diff.<driver>.command::
 103        The custom diff driver command.  See linkgit:gitattributes[5]
 104        for details.
 105
 106diff.<driver>.xfuncname::
 107        The regular expression that the diff driver should use to
 108        recognize the hunk header.  A built-in pattern may also be used.
 109        See linkgit:gitattributes[5] for details.
 110
 111diff.<driver>.binary::
 112        Set this option to true to make the diff driver treat files as
 113        binary.  See linkgit:gitattributes[5] for details.
 114
 115diff.<driver>.textconv::
 116        The command that the diff driver should call to generate the
 117        text-converted version of a file.  The result of the
 118        conversion is used to generate a human-readable diff.  See
 119        linkgit:gitattributes[5] for details.
 120
 121diff.<driver>.wordregex::
 122        The regular expression that the diff driver should use to
 123        split words in a line.  See linkgit:gitattributes[5] for
 124        details.
 125
 126diff.<driver>.cachetextconv::
 127        Set this option to true to make the diff driver cache the text
 128        conversion outputs.  See linkgit:gitattributes[5] for details.
 129
 130diff.tool::
 131        The diff tool to be used by linkgit:git-difftool[1].  This
 132        option overrides `merge.tool`, and has the same valid built-in
 133        values as `merge.tool` minus "tortoisemerge" and plus
 134        "kompare".  Any other value is treated as a custom diff tool,
 135        and there must be a corresponding `difftool.<tool>.cmd`
 136        option.
