6 App::GitHooks - Extensible plugins system for git hooks.
7
9 Version 1.9.0
10
12 "App::GitHooks" is an extensible and easy to configure git hooks
13 framework that supports many plugins.
14
15 Here's an example of it in action, running the "pre-commit" hook checks
16 before the commit message can be entered:
17
18 Here is another example, with a Perl file that fails compilation this
19 time:
20
22 1. Install this distribution (with cpanm or your preferred CPAN
23 client):
24
25 cpanm App::GitHooks
26
27 2. Install the plugins you are interested in (with cpanm or your
28 prefered CPAN client), as "App::GitHooks" does not bundle them. See
29 the list of plugins below, but for example:
30
31 cpanm App::GitHooks::Plugin::BlockNOCOMMIT
32 cpanm App::GitHooks::Plugin::DetectCommitNoVerify
33 ...
34
35 3. Go to the git repository for which you want to set up git hooks,
36 and run:
37
38 githooks install
39
40 4. Enjoy!
41
43 App::GitHooks requires git v1.7.4.1 or above.

140
141 • App::GitHooks::Plugin::PreventTrailingWhitespace
142
143 Prevent trailing whitespace from being committed.
144
146 Configuration format
147 App::GitHooks uses Config::Tiny, so the configuration should follow the
148 following format:
149
150 general_key_1 = value
151 general_key_2 = value
152
153 [section_1]
154 section_1_key 1 = value
155
156 The file is divided between the global configuration options at the
157 beginning of the file (such as "general_key_1" above) and plugin
158 specific configuration options which are located in distinct sections
159 (such as "section_1_key" in the "[section_1]" section).
160
161 Configuration file locations
162 App::GitHooks supports setting custom options by creating one of the
163 following files, which are searched in descending order of preference:
164
165 • A file of any name anywhere on your system, if you set the
166 environment variable "GITHOOKSRC_FORCE" to its path.
167
168 Note that you should normally use "GITHOOKSRC". This option is
169 provided mostly for testing purposes, when configuration options
170 for testing in a reliable manner are of the utmost importance and
171 take precedence over any repository-specific settings.
172
173 • A ".githooksrc" file at the root of the git repository.
174
175 The settings will then only apply to that repository.
176
177 • A file of any name anywhere on your system, if you set the
178 environment variable "GITHOOKSRC" to its path.
179
180 Note that ".githooksrc" files at the top of a repository or in a
181 user's home directory will take precedence over a file specified by
182 the "GITHOOKSRC" environment variable.
183
184 • A ".githooksrc" file in the home directory of the current user.
185
186 The settings will then apply to all the repositories that have
187 hooks set up. Note that if ".githooksrc" file is defined at the
188 root of a repository, that configuration file will take precedence
189 over the one defined in the home directory of the current user (as
190 it is presumably more specific). Auto-merge of options across
191 multiple ".githooksrc" files in an inheritance fashion is not
192 currently supported.
193
194 General configuration options
195 • project_prefixes
196
197 A comma-separated list of project prefixes, in case you want to use
198 this in "extract_ticket_id_from_commit" or
199 "extract_ticket_id_from_branch".
200
201 project_prefixes = OPS, DEV
202
203 • extract_ticket_id_from_commit
204
205 A regular expression with _one_ capturing group that will be
206 applied to the first line of a commit message to extract the ticket
207 ID referenced, if there is one.
208
209 extract_ticket_id_from_commit = /^($project_prefixes-\d+|--): /
210
211 • extract_ticket_id_from_branch
212
213 A regular expression with _one_ capturing group that will be
214 applied to branch names to extract a ticket ID. This allows
215 creating one branch per ticket and having the hooks check that the
216 commit messages and the branch names are in sync.
217
218 extract_ticket_id_from_branch = /^($project_prefixes-?\d+)/
219
220 • normalize_branch_ticket_id
221
222 A replacement expression that normalizes the ticket ID captured
223 with "extract_ticket_id_from_branch".
224
225 normalize_branch_ticket_id = s/^(.*?)-?(\d+)$/\U$1-$2/
226
227 • skip_directories
228
229 A regular expression to filter the directory names that should be
230 skipped when analyzing files as part of file-level checks.
231
232 skip_directories = /^cpan(?:-[^\/]+)?\//
233
234 • force_plugins
235
236 A comma-separated list of the plugins that must be present on the
237 system and will be executed. If any plugins from this list are
238 missing, the action will error out. If any other plugins not in
239 this list are installed on the system, they will be ignored.
240
241 force_plugins = App::GitHooks::Plugin::ValidatePODFormat, App::GitHooks::Plugin::RequireCommitMessage
242
243 • min_app_githooks_version
244
245 Specify the minimum version of App::GitHooks.
246
247 min_app_githooks_version = 1.9.0
248
249 Testing-specific options
250 • limit_plugins
251
252 Deprecated. Use "force_plugins" instead.
253
254 • force_interactive
255
256 Force the application to consider that the terminal is interactive
257 (`1`) or non-interactive (`0`) independently of whether the actual
258 STDOUT is interactive or not.
259
260 • force_use_colors
261
262 Force the output to use colors (`1`) or to not use colors (`0`)
263 independently of the ability of STDOUT to display colors.
264
265 • force_is_utf8
266
267 Allows the output to use utf-8 characters (`1`) or not (`0`),
268 independently of whether the output declares supporting utf-8.
269
270 • commit_msg_no_edit
271
272 Allows skipping the loop to edit the message when the commit
273 message checks failed.
274
276 GITHOOKS_SKIP
277 Comma separated list of hooks to skip. A warning is issued for each
278 hook that would otherwise be triggered.
279
280 GITHOOKS_SKIP=pre-commit,update
281
282 GITHOOKS_DISABLE
283 Works similarly to "GITHOOKS_SKIP", but it skips all the possible
284 hooks. Set it to a true value, e.g. 1.
285
286 GITHOOKS_DISABLE=1
287
288 GITHOOKSRC
289 Contains path to a custom configuration file, see "Configuration file
290 locations" above.

294 file locations" above.

450
451 my $string = $app->wrap( $information, $indent );
452
453 color()
454 Print text with colors.
455
456 $app->color( $color, $text );
457
459 _to_camelcase()
460 Convert a dash-separated string to camelcase.
461
462 my $camelcase_string = App::GitHooks::_to_camelcase( $string );
463
464 This function is useful to convert git hook names (commit-msg) to
465 module names (CommitMsg).
466
467 _should_skip()
468 See the environment variables GITHOOKS_SKIP and GITHOOKS_DISABLE above.
469 This function returns the variable name that would be the reason to
470 skip the given hook, or nothing.
471
472 return if _should_skip( $name );
473
475 Manual installation
476 Symlink your git hooks under .git/hooks to a file with the following
477 content:
478
479 #!/usr/bin/perl
480
481 use strict;
482 use warnings;
483
484 use App::GitHooks;
485
486 App::GitHooks->run(
487 name => $0,
488 arguments => \@ARGV,
489 );
490
491 All you need to do then is install the plugins you are interested in!
492
493 This distribution also includes a "hooks/" directory that you can
494 symlink / copy to ".git/hooks/" instead , to get all the hooks set up
495 properly in one swoop.
496
497 Important: adjust "#!/usr/bin/perl" as needed, if that line is not a
498 valid interpreter, your git actions will fail with "error: cannot run
499 .git/hooks/[hook name]: No such file or directory".
500
502 Please report any bugs or feature requests through the web interface at
503 <https://github.com/guillaumeaubert/App-GitHooks/issues/new>. I will
504 be notified, and then you'll automatically be notified of progress on
505 your bug as I make changes.
