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