138 | Highlight changed words using only colors. Implies `--color`. | |
139 | plain:: | |
140 | Show words as `[-removed-]` and `{+added+}`. Makes no | |
141 | attempts to escape the delimiters if they appear in the input, | |
142 | so the output may be ambiguous. | |
143 | porcelain:: | |
144 | Use a special line-based format intended for script | |
145 | consumption. Added/removed/unchanged runs are printed in the | |
146 | usual unified diff format, starting with a `+`/`-`/` ` | |
147 | character at the beginning of the line and extending to the | |
148 | end of the line. Newlines in the input are represented by a | |
149 | tilde `~` on a line of its own. | |
150 | none:: | |
151 | Disable word diff again. | |

155 | highlight the changed parts in all modes if enabled. | |
156 | ||
157 | --word-diff-regex=<regex>:: | |
158 | Use <regex> to decide what a word is, instead of considering | |
159 | runs of non-whitespace to be a word. Also implies | |
160 | `--word-diff` unless it was already enabled. | |
2b6a5417 | 161 | + |
882749a0 | 162 | Every non-overlapping match of the |
c4b252c3 TR |
163 | <regex> is considered a word. Anything between these matches is |
164 | considered whitespace and ignored(!) for the purposes of finding | |
165 | differences. You may want to append `|[^[:space:]]` to your regular | |
166 | expression to make sure that it matches all non-whitespace characters. | |
167 | A match that contains a newline is silently truncated(!) at the | |
168 | newline. | |
80c49c3d | 169 | + |
98a4d87b BSSJ |
170 | The regex can also be set via a diff driver or configuration option, see |
171 | linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly | |
172 | overrides any diff driver or configuration setting. Diff drivers | |
173 | override configuration settings. | |

202 | Instead of showing the full 40-byte hexadecimal object |
203 | name in diff-raw format output and diff-tree header | |
323b9db8 | 204 | lines, show only a partial prefix. This is |
dce5ef14 | 205 | independent of the `--full-index` option above, which controls |
913419fc | 206 | the diff-patch output format. Non default number of |
dce5ef14 | 207 | digits can be specified with `--abbrev=<n>`. |

37ab5156 | 210 | --break-rewrites[=[<n>][/<m>]]:: |
cf958afd MM |
211 | Break complete rewrite changes into pairs of delete and |
212 | create. This serves two purposes: | |
213 | + | |
214 | It affects the way a change that amounts to a total rewrite of a file | |
215 | not as a series of deletion and insertion mixed together with a very | |
216 | few lines that happen to match textually as the context, but as a | |
217 | single deletion of everything old followed by a single insertion of | |
218 | everything new, and the number `m` controls this aspect of the -B | |
219 | option (defaults to 60%). `-B/70%` specifies that less than 30% of the | |
220 | original should remain in the result for git to consider it a total | |
221 | rewrite (i.e. otherwise the resulting patch will be a series of | |
222 | deletion and insertion mixed together with context lines). | |
223 | + | |
224 | When used with -M, a totally-rewritten file is also considered as the | |
225 | source of a rename (usually -M only considers a file that disappeared | |
226 | as the source of a rename), and the number `n` controls this aspect of | |
227 | the -B option (defaults to 50%). `-B20%` specifies that a change with | |
228 | addition and deletion compared to 20% or more of the file's size are | |
229 | eligible for being picked up as a possible source of a rename to | |
230 | another file. | |

237 | ifdef::git-log[] | |
238 | If generating diffs, detect and report renames for each commit. | |
239 | For following files across renames while traversing history, see | |
240 | `--follow`. | |
241 | endif::git-log[] | |
cf958afd MM |
242 | If `n` is specified, it is a is a threshold on the similarity |
243 | index (i.e. amount of addition/deletions compared to the | |
244 | file's size). For example, `-M90%` means git should consider a | |
245 | delete/add pair to be a rename if more than 90% of the file | |
246 | hasn't changed. | |
dda2d79a | 247 | |
cf958afd | 248 | -C[<n>]:: |
37ab5156 | 249 | --detect-copies[=<n>]:: |
ca6c0970 | 250 | Detect copies as well as renames. See also `--find-copies-harder`. |
cf958afd | 251 | If `n` is specified, it has the same meaning as for `-M<n>`. |
dda2d79a JH |
252 | |
253 | --find-copies-harder:: | |
ca6c0970 | 254 | For performance reasons, by default, `-C` option finds copies only |
a6080a0a | 255 | if the original file of the copy was modified in the same |
f73ae1fc | 256 | changeset. This flag makes the command |
dda2d79a JH |
257 | inspect unmodified files as candidates for the source of |
258 | copy. This is a very expensive operation for large | |
ca6c0970 JS |
259 | projects, so use it with caution. Giving more than one |
260 | `-C` option has the same effect. | |
dda2d79a | 261 | |
8082d8d3 | 262 | -l<num>:: |
dce5ef14 | 263 | The `-M` and `-C` options require O(n^2) processing time where n |
f73ae1fc | 264 | is the number of potential rename/copy targets. This |
8082d8d3 | 265 | option prevents rename/copy detection from running if |
f73ae1fc | 266 | the number of rename/copy targets exceeds the specified |
8082d8d3 JH |
