1// Please don't remove this comment as asciidoc behaves badly when 2// the first non-empty line is ifdef/ifndef. The symptom is that 3// without this comment the <git-diff-core> attribute conditionally 4// defined below ends up being defined unconditionally. 5// Last checked with asciidoc 7.0.2. 6 7ifndef::git-format-patch[] 8ifndef::git-diff[] 9ifndef::git-log[] 10:git-diff-core: 1 11endif::git-log[] 12endif::git-diff[] 13endif::git-format-patch[] 14 15ifdef::git-format-patch[] 16-p:: 17 Generate patches without diffstat. 18endif::git-format-patch[] 19 20ifndef::git-format-patch[] 21-p:: 22-u:: 23 Generate patch (see section on generating patches). 24 {git-diff? This is the default.} 25endif::git-format-patch[] 26 27-U<n>:: 28--unified=<n>:: 29 Generate diffs with <n> lines of context instead of 30 the usual three. Implies "-p". 31 32--raw:: 33 Generate the raw format. 34 {git-diff-core? This is the default.} 35 36--patch-with-raw:: 37 Synonym for "-p --raw". 38 39--stat[=width[,name-width]]:: 40 Generate a diffstat. You can override the default 41 output width for 80-column terminal by "--stat=width". 42 The width of the filename part can be controlled by 43 giving another width to it separated by a comma. 44 45--numstat:: 46 Similar to \--stat, but shows number of added and 47 deleted lines in decimal notation and pathname without 48 abbreviation, to make it more machine friendly. For 49 binary files, outputs two `-` instead of saying 50 `0 0`. 51 52--shortstat:: 53 Output only the last line of the --stat format containing total 54 number of modified files, as well as number of added and deleted 55 lines. 56 57--dirstat[=limit]:: 58 Output the distribution of relative amount of changes (number of lines added or 59 removed) for each sub-directory. Directories with changes below 60 a cut-off percent (3% by default) are not shown. The cut-off percent 61 can be set with "--dirstat=limit". Changes in a child directory is not 62 counted for the parent directory, unless "--cumulative" is used. 63 64--dirstat-by-file[=limit]:: 65 Same as --dirstat, but counts changed files instead of lines. 66 67--summary:: 68 Output a condensed summary of extended header information 69 such as creations, renames and mode changes. 70 71--patch-with-stat:: 72 Synonym for "-p --stat". 73 {git-format-patch? This is the default.} 74 75-z:: 76 NUL-line termination on output. This affects the --raw 77 output field terminator. Also output from commands such 78 as "git-log" will be delimited with NUL between commits. 79 80--name-only:: 81 Show only names of changed files. 82 83--name-status:: 84 Show only names and status of changed files. See the description 85 of the `--diff-filter` option on what the status letters mean. 86 87--color:: 88 Show colored diff. 89 90--no-color:: 91 Turn off colored diff, even when the configuration file 92 gives the default to color output. 93 94--color-words:: 95 Show colored word diff, i.e. color words which have changed. 96 97--no-renames:: 98 Turn off rename detection, even when the configuration 99 file gives the default to do so. 100 101--check:: 102 Warn if changes introduce trailing whitespace 103 or an indent that uses a space before a tab. Exits with 104 non-zero status if problems are found. Not compatible with 105 --exit-code. 106 107--full-index:: 108 Instead of the first handful of characters, show the full 109 pre- and post-image blob object names on the "index" 110 line when generating patch format output. 111 112--binary:: 113 In addition to --full-index, output "binary diff" that 114 can be applied with "git apply". 115 116--abbrev[=<n>]:: 117 Instead of showing the full 40-byte hexadecimal object 118 name in diff-raw format output and diff-tree header 119 lines, show only handful hexdigits prefix. This is 120 independent of --full-index option above, which controls 121 the diff-patch output format. Non default number of 122 digits can be specified with --abbrev=<n>. 123 124-B:: 125 Break complete rewrite changes into pairs of delete and create. 126 127-M:: 128 Detect renames. 129 130-C:: 131 Detect copies as well as renames. See also `--find-copies-harder`. 132 133--diff-filter=[ACDMRTUXB*]:: 134 Select only files that are Added (`A`), Copied (`C`), 135 Deleted (`D`), Modified (`M`), Renamed (`R`), have their 136 type (i.e. regular file, symlink, submodule, ...) changed (`T`), 137 are Unmerged (`U`), are 138 Unknown (`X`), or have had their pairing Broken (`B`). 139 Any combination of the filter characters may be used. 140 When `*` (All-or-none) is added to the combination, all 141 paths are selected if there is any file that matches 142 other criteria in the comparison; if there is no file 143 that matches other criteria, nothing is selected. 144 145--find-copies-harder:: 146 For performance reasons, by default, `-C` option finds copies only 147 if the original file of the copy was modified in the same 148 changeset. This flag makes the command 149 inspect unmodified files as candidates for the source of 150 copy. This is a very expensive operation for large 151 projects, so use it with caution. Giving more than one 152 `-C` option has the same effect. 153 154-l<num>:: 155 -M and -C options require O(n^2) processing time where n 156 is the number of potential rename/copy targets. This 157 option prevents rename/copy detection from running if 158 the number of rename/copy targets exceeds the specified 159 number. 160 161-S<string>:: 162 Look for differences that contain the change in <string>. 163 164--pickaxe-all:: 165 When -S finds a change, show all the changes in that 166 changeset, not just the files that contain the change 167 in <string>. 168 169--pickaxe-regex:: 170 Make the <string> not a plain string but an extended POSIX 171 regex to match. 172 173-O<orderfile>:: 174 Output the patch in the order specified in the 175 <orderfile>, which has one shell glob pattern per line. 176 177-R:: 178 Swap two inputs; that is, show differences from index or 179 on-disk file to tree contents. 180 181--relative[=<path>]:: 182 When run from a subdirectory of the project, it can be 183 told to exclude changes outside the directory and show 184 pathnames relative to it with this option. When you are 185 not in a subdirectory (e.g. in a bare repository), you 186 can name which subdirectory to make the output relative 187 to by giving a <path> as an argument. 188 189-a:: 190--text:: 191 Treat all files as text. 192 193--ignore-space-at-eol:: 194 Ignore changes in whitespace at EOL. 195 196-b:: 197--ignore-space-change:: 198 Ignore changes in amount of whitespace. This ignores whitespace 199 at line end, and considers all other sequences of one or 200 more whitespace characters to be equivalent. 201 202-w:: 203--ignore-all-space:: 204 Ignore whitespace when comparing lines. This ignores 205 differences even if one line has whitespace where the other 206 line has none. 207 208--exit-code:: 209 Make the program exit with codes similar to diff(1). 210 That is, it exits with 1 if there were differences and 211 0 means no differences. 212 213--quiet:: 214 Disable all output of the program. Implies --exit-code. 215 216--ext-diff:: 217 Allow an external diff helper to be executed. If you set an 218 external diff driver with linkgit:gitattributes[5], you need 219 to use this option with linkgit:git-log[1] and friends. 220 221--no-ext-diff:: 222 Disallow external diff drivers. 223 224--ignore-submodules:: 225 Ignore changes to submodules in the diff generation. 226 227--src-prefix=<prefix>:: 228 Show the given source prefix instead of "a/". 229 230--dst-prefix=<prefix>:: 231 Show the given destination prefix instead of "b/". 232 233--no-prefix:: 234 Do not show any source or destination prefix. 235 236For more detailed explanation on these common options, see also 237linkgit:gitdiffcore[7].
