21 | DESCRIPTION | |
22 | ----------- | |
0979c106 | 23 | Reads supplied 'diff' output and applies it on a git index file |
d0587fd5 JH |
24 | and a work tree. |
25 | ||
26 | OPTIONS | |
27 | ------- | |
12dd6e8c | 28 | <patch>...:: |
1d035f85 | 29 | The files to read the patch from. '-' can be used to read |
12dd6e8c | 30 | from the standard input. |
d0587fd5 | 31 | |
d0587fd5 JH |
32 | --stat:: |
33 | Instead of applying the patch, output diffstat for the | |
12dd6e8c | 34 | input. Turns off "apply". |
d0587fd5 | 35 | |
7d8b7c21 | 36 | --numstat:: |
1d035f85 DM |
37 | Similar to \--stat, but shows the number of added and |
38 | deleted lines in decimal notation and the pathname without | |
2f89543e JH |
39 | abbreviation, to make it more machine friendly. For |
40 | binary files, outputs two `-` instead of saying | |
41 | `0 0`. Turns off "apply". | |
7d8b7c21 | 42 | |
d0587fd5 JH |
43 | --summary:: |
44 | Instead of applying the patch, output a condensed | |
45 | summary of information obtained from git diff extended | |
46 | headers, such as creations, renames and mode changes. | |
12dd6e8c | 47 | Turns off "apply". |
d0587fd5 JH |
48 | |
49 | --check:: | |
50 | Instead of applying the patch, see if the patch is | |
51 | applicable to the current work tree and/or the index | |
12dd6e8c | 52 | file and detects errors. Turns off "apply". |
d0587fd5 JH |
53 | |
54 | --index:: | |
55 | When --check is in effect, or when applying the patch | |
56 | (which is the default when none of the options that | |
57 | disables it is in effect), make sure the patch is | |
58 | applicable to what the current index file records. If | |
59 | the file to be patched in the work tree is not | |
60 | up-to-date, it is flagged as an error. This flag also | |
61 | causes the index file to be updated. | |
62 | ||
5684ed6d | 63 | --cached:: |
1d035f85 DM |
64 | Apply a patch without touching the working tree. Instead take the |
65 | cached data, apply the patch, and store the result in the index | |
5684ed6d JF |
66 | without using the working tree. This implies '--index'. |
67 | ||
f26c4940 | 68 | --build-fake-ancestor=<file>:: |
ba020ef5 | 69 | Newer 'git-diff' output has embedded 'index information' |
d88156e9 JH |
70 | for each blob to help identify the original version that |
71 | the patch applies to. When this flag is given, and if | |
1d035f85 | 72 | the original versions of the blobs are available locally, |
7a988699 JS |
73 | builds a temporary index containing those blobs. |
74 | + | |
75 | When a pure mode change is encountered (which has no index information), | |
76 | the information is read from the current index instead. | |
d88156e9 | 77 | |
3240240f SB |
78 | -R:: |
79 | --reverse:: | |
5684ed6d JF |
80 | Apply the patch in reverse. |
81 | ||
82 | --reject:: | |
ba020ef5 | 83 | For atomicity, 'git-apply' by default fails the whole patch and |
5684ed6d JF |
84 | does not touch the working tree when some of the hunks |
85 | do not apply. This option makes it apply | |
b32d37a3 | 86 | the parts of the patch that are applicable, and leave the |
8938045a | 87 | rejected hunks in corresponding *.rej files. |
5684ed6d | 88 | |
d88156e9 JH |
89 | -z:: |
90 | When showing the index information, do not munge paths, | |
91 | but use NUL terminated machine readable format. Without | |
92 | this flag, the pathnames output will have TAB, LF, and | |
93 | backslash characters replaced with `\t`, `\n`, and `\\`, | |
94 | respectively. | |
95 | ||
e36f8b60 DB |
96 | -p<n>:: |
97 | Remove <n> leading slashes from traditional diff paths. The | |
98 | default is 1. | |
99 | ||
47495887 EB |
100 | -C<n>:: |
101 | Ensure at least <n> lines of surrounding context match before | |
102 | and after each change. When fewer lines of surrounding | |
74237d62 | 103 | context exist they all must match. By default no context is |
47495887 EB |
104 | ever ignored. |
105 | ||
f58bb6fb | 106 | --unidiff-zero:: |
ba020ef5 | 107 | By default, 'git-apply' expects that the patch being |
f58bb6fb JF |
108 | applied is a unified diff with at least one line of context. |
109 | This provides good safety measures, but breaks down when | |
110 | applying a diff generated with --unified=0. To bypass these | |
111 | checks use '--unidiff-zero'. | |
112 | + | |
1d035f85 | 113 | Note, for the reasons stated above usage of context-free patches is |
f58bb6fb JF |
114 | discouraged. |
115 | ||
12dd6e8c | 116 | --apply:: |
5684ed6d | 117 | If you use any of the options marked "Turns off |
ba020ef5 | 118 | 'apply'" above, 'git-apply' reads and outputs the |
1d035f85 | 119 | requested information without actually applying the |
12dd6e8c JH |
120 | patch. Give this flag after those flags to also apply |
121 | the patch. | |
122 | ||
e433705d JH |
123 | --no-add:: |
124 | When applying a patch, ignore additions made by the | |
71a9883d | 125 | patch. This can be used to extract the common part between |
2fd02c92 | 126 | two files by first running 'diff' on them and applying |
e433705d | 127 | the result with this option, which would apply the |
1d035f85 | 128 | deletion part but not the addition part. |
d0587fd5 | 129 | |
3240240f SB |
130 | --allow-binary-replacement:: |
131 | --binary:: | |
2b6eef94 JH |
132 | Historically we did not allow binary patch applied |
133 | without an explicit permission from the user, and this | |
134 | flag was the way to do so. Currently we always allow binary | |
135 | patch application, so this is a no-op. | |
27dedf0c | 136 | |
5684ed6d JF |
137 | --exclude=<path-pattern>:: |
138 | Don't apply changes to files matching the given path pattern. This can | |
139 | be useful when importing patchsets, where you want to exclude certain | |
140 | files or directories. | |
141 | ||
6ecb1ee2 JH |
142 | --include=<path-pattern>:: |
143 | Apply changes to files matching the given path pattern. This can | |
144 | be useful when importing patchsets, where you want to include certain | |
145 | files or directories. | |
146 | + | |
147 | When --exclude and --include patterns are used, they are examined in the | |
148 | order they appear on the command line, and the first match determines if a | |
149 | patch to each path is used. A patch to a path that does not match any | |
150 | include/exclude pattern is used by default if there is no include pattern | |
151 | on the command line, and ignored if there is any include pattern. | |
152 | ||
86c91f91 GB |
153 | --ignore-space-change:: |
154 | --ignore-whitespace:: | |
155 | When applying a patch, ignore changes in whitespace in context | |
156 | lines if necessary. | |
157 | Context lines will preserve their whitespace, and they will not | |
158 | undergo whitespace fixing regardless of the value of the | |
159 | `--whitespace` option. New lines will still be fixed, though. | |
160 | ||
91af7ae5 JH |
161 | --whitespace=<action>:: |
162 | When applying a patch, detect a new or modified line that has | |
163 | whitespace errors. What are considered whitespace errors is | |
164 | controlled by `core.whitespace` configuration. By default, | |
165 | trailing whitespaces (including lines that solely consist of | |
166 | whitespaces) and a space character that is immediately followed | |
167 | by a tab character inside the initial indent of the line are | |
168 | considered whitespace errors. | |
169 | + | |
170 | By default, the command outputs warning messages but applies the patch. | |
eb006ccf | 171 | When `git-apply` is used for statistics and not applying a |
91af7ae5 JH |
172 | patch, it defaults to `nowarn`. |
173 | + | |
1d035f85 | 174 | You can use different `<action>` values to control this |
91af7ae5 | 175 | behavior: |
8273c79a JH |
176 | + |
177 | * `nowarn` turns off the trailing whitespace warning. | |
178 | * `warn` outputs warnings for a few such errors, but applies the | |
91af7ae5 JH |
179 | patch as-is (default). |
180 | * `fix` outputs warnings for a few such errors, and applies the | |
181 | patch after fixing them (`strip` is a synonym --- the tool | |
1d035f85 | 182 | used to consider only trailing whitespace characters as errors, and the |
91af7ae5 | 183 | fix involved 'stripping' them, but modern gits do more). |
8273c79a JH |
184 | * `error` outputs warnings for a few such errors, and refuses |
185 | to apply the patch. | |
186 | * `error-all` is similar to `error` but shows all errors. | |
8273c79a | 187 | |
f847c07b | 188 | --inaccurate-eof:: |
0979c106 | 189 | Under certain circumstances, some versions of 'diff' do not correctly |
5684ed6d | 190 | detect a missing new-line at the end of the file. As a result, patches |
0979c106 | 191 | created by such 'diff' programs do not record incomplete lines |
5684ed6d JF |
192 | correctly. This option adds support for applying such patches by |
193 | working around this bug. | |
194 | ||
3240240f SB |
195 | -v:: |
196 | --verbose:: | |
5684ed6d JF |
197 | Report progress to stderr. By default, only a message about the |
198 | current patch being applied will be printed. This option will cause | |
199 | additional information to be reported. | |
8273c79a | 200 | |
c14b9d1e JS |
201 | --recount:: |
202 | Do not trust the line counts in the hunk headers, but infer them | |
203 | by inspecting the patch (e.g. after editing the patch without | |
204 | adjusting the hunk headers appropriately). | |
205 | ||
f5563887 | 206 | --directory=<root>:: |
1d035f85 | 207 | Prepend <root> to all filenames. If a "-p" argument was also passed, |
c4730f35 | 208 | it is applied before prepending the new root. |
f5563887 JH |
209 | + |
210 | For example, a patch that talks about updating `a/git-gui.sh` to `b/git-gui.sh` | |
211 | can be applied to the file in the working tree `modules/git-gui/git-gui.sh` by | |
212 | running `git apply --directory=modules/git-gui`. | |
c4730f35 | 213 | |
8273c79a JH |
214 | Configuration |
215 | ------------- | |
216 | ||
86c91f91 GB |
217 | apply.ignorewhitespace:: |
218 | Set to 'change' if you want changes in whitespace to be ignored by default. | |
219 | Set to one of: no, none, never, false if you want changes in | |
220 | whitespace to be significant. | |
8273c79a JH |
221 | apply.whitespace:: |
222 | When no `--whitespace` flag is given from the command | |
223 | line, this configuration item is used as the default. | |
224 | ||
e06c5a6c SV |
225 | Submodules |
226 | ---------- | |
ba020ef5 | 227 | If the patch contains any changes to submodules then 'git-apply' |
e06c5a6c SV |
228 | treats these changes as follows. |
229 | ||
230 | If --index is specified (explicitly or implicitly), then the submodule | |
231 | commits must match the index exactly for the patch to apply. If any | |
232 | of the submodules are checked-out, then these check-outs are completely | |
233 | ignored, i.e., they are not required to be up-to-date or clean and they | |
234 | are not updated. | |
235 | ||
236 | If --index is not specified, then the submodule commits in the patch | |
1d035f85 | 237 | are ignored and only the absence or presence of the corresponding |
e06c5a6c | 238 | subdirectory is checked and (if possible) updated. |
