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--patience:: 40 Generate a diff using the "patience diff" algorithm. 41 42--stat[=width[,name-width]]:: 43 Generate a diffstat. You can override the default 44 output width for 80-column terminal by "--stat=width". 45 The width of the filename part can be controlled by 46 giving another width to it separated by a comma. 47 48--numstat:: 49 Similar to \--stat, but shows number of added and 50 deleted lines in decimal notation and pathname without 51 abbreviation, to make it more machine friendly. For 52 binary files, outputs two `-` instead of saying 53 `0 0`. 54 55--shortstat:: 56 Output only the last line of the --stat format containing total 57 number of modified files, as well as number of added and deleted 58 lines. 59 60--dirstat[=limit]:: 61 Output the distribution of relative amount of changes (number of lines added or 62 removed) for each sub-directory. Directories with changes below 63 a cut-off percent (3% by default) are not shown. The cut-off percent 64 can be set with "--dirstat=limit". Changes in a child directory is not 65 counted for the parent directory, unless "--cumulative" is used. 66 67--dirstat-by-file[=limit]:: 68 Same as --dirstat, but counts changed files instead of lines. 69 70--summary:: 71 Output a condensed summary of extended header information 72 such as creations, renames and mode changes. 73 74--patch-with-stat:: 75 Synonym for "-p --stat". 76 {git-format-patch? This is the default.} 77 78-z:: 79 NUL-line termination on output. This affects the --raw 80 output field terminator. Also output from commands such 81 as "git-log" will be delimited with NUL between commits. 82 83--name-only:: 84 Show only names of changed files. 85 86--name-status:: 87 Show only names and status of changed files. See the description 88 of the `--diff-filter` option on what the status letters mean. 89 90--color:: 91 Show colored diff. 92 93--no-color:: 94 Turn off colored diff, even when the configuration file 95 gives the default to color output. 96 97--color-words[=<regex>]:: 98 Show colored word diff, i.e., color words which have changed. 99 By default, words are separated by whitespace. 100+ 101When a <regex> is specified, every non-overlapping match of the 102<regex> is considered a word. Anything between these matches is 103considered whitespace and ignored(!) for the purposes of finding 104differences. You may want to append `|[^[:space:]]` to your regular 105expression to make sure that it matches all non-whitespace characters. 106A match that contains a newline is silently truncated(!) at the 107newline. 108+ 109The regex can also be set via a diff driver or configuration option, see 110linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly 111overrides any diff driver or configuration setting. Diff drivers 112override configuration settings. 113 114--no-renames:: 115 Turn off rename detection, even when the configuration 116 file gives the default to do so. 117 118--check:: 119 Warn if changes introduce trailing whitespace 120 or an indent that uses a space before a tab. Exits with 121 non-zero status if problems are found. Not compatible with 122 --exit-code. 123 124--full-index:: 125 Instead of the first handful of characters, show the full 126 pre- and post-image blob object names on the "index" 127 line when generating patch format output. 128 129--binary:: 130 In addition to --full-index, output "binary diff" that 131 can be applied with "git apply". 132 133--abbrev[=<n>]:: 134 Instead of showing the full 40-byte hexadecimal object 135 name in diff-raw format output and diff-tree header 136 lines, show only a partial prefix. This is 137 independent of --full-index option above, which controls 138 the diff-patch output format. Non default number of 139 digits can be specified with --abbrev=<n>. 140 141-B:: 142 Break complete rewrite changes into pairs of delete and create. 143 144-M:: 145 Detect renames. 146 147-C:: 148 Detect copies as well as renames. See also `--find-copies-harder`. 149 150--diff-filter=[ACDMRTUXB*]:: 151 Select only files that are Added (`A`), Copied (`C`), 152 Deleted (`D`), Modified (`M`), Renamed (`R`), have their 153 type (i.e. regular file, symlink, submodule, ...) changed (`T`), 154 are Unmerged (`U`), are 155 Unknown (`X`), or have had their pairing Broken (`B`). 156 Any combination of the filter characters may be used. 157 When `*` (All-or-none) is added to the combination, all 158 paths are selected if there is any file that matches 159 other criteria in the comparison; if there is no file 160 that matches other criteria, nothing is selected. 161 162--find-copies-harder:: 163 For performance reasons, by default, `-C` option finds copies only 164 if the original file of the copy was modified in the same 165 changeset. This flag makes the command 166 inspect unmodified files as candidates for the source of 167 copy. This is a very expensive operation for large 168 projects, so use it with caution. Giving more than one 169 `-C` option has the same effect. 170 171-l<num>:: 172 -M and -C options require O(n^2) processing time where n 173 is the number of potential rename/copy targets. This 174 option prevents rename/copy detection from running if 175 the number of rename/copy targets exceeds the specified 176 number. 177 178-S<string>:: 179 Look for differences that contain the change in <string>. 180 181--pickaxe-all:: 182 When -S finds a change, show all the changes in that 183 changeset, not just the files that contain the change 184 in <string>. 185 186--pickaxe-regex:: 187 Make the <string> not a plain string but an extended POSIX 188 regex to match. 189 190-O<orderfile>:: 191 Output the patch in the order specified in the 192 <orderfile>, which has one shell glob pattern per line. 193 194-R:: 195 Swap two inputs; that is, show differences from index or 196 on-disk file to tree contents. 197 198--relative[=<path>]:: 199 When run from a subdirectory of the project, it can be 200 told to exclude changes outside the directory and show 201 pathnames relative to it with this option. When you are 202 not in a subdirectory (e.g. in a bare repository), you 203 can name which subdirectory to make the output relative 204 to by giving a <path> as an argument. 205 206-a:: 207--text:: 208 Treat all files as text. 209 210--ignore-space-at-eol:: 211 Ignore changes in whitespace at EOL. 212 213-b:: 214--ignore-space-change:: 215 Ignore changes in amount of whitespace. This ignores whitespace 216 at line end, and considers all other sequences of one or 217 more whitespace characters to be equivalent. 218 219-w:: 220--ignore-all-space:: 221 Ignore whitespace when comparing lines. This ignores 222 differences even if one line has whitespace where the other 223 line has none. 224 225--inter-hunk-context=<lines>:: 226 Show the context between diff hunks, up to the specified number 227 of lines, thereby fusing hunks that are close to each other. 228 229--exit-code:: 230 Make the program exit with codes similar to diff(1). 231 That is, it exits with 1 if there were differences and 232 0 means no differences. 233 234--quiet:: 235 Disable all output of the program. Implies --exit-code. 236 237--ext-diff:: 238 Allow an external diff helper to be executed. If you set an 239 external diff driver with linkgit:gitattributes[5], you need 240 to use this option with linkgit:git-log[1] and friends. 241 242--no-ext-diff:: 243 Disallow external diff drivers. 244 245--ignore-submodules:: 246 Ignore changes to submodules in the diff generation. 247 248--src-prefix=<prefix>:: 249 Show the given source prefix instead of "a/". 250 251--dst-prefix=<prefix>:: 252 Show the given destination prefix instead of "b/". 253 254--no-prefix:: 255 Do not show any source or destination prefix. 256 257For more detailed explanation on these common options, see also 258linkgit:gitdiffcore[7].
