6 Module::Find - Find and use installed modules in a (sub)category
7
9 use Module::Find;
10 # use all modules in the Plugins/ directory
12 @found = usesub Mysoft::Plugins;
13 # use modules in all subdirectories
15 @found = useall Mysoft::Plugins;
16 # find all DBI::... modules
18 @found = findsubmod DBI;
19 # find anything in the CGI/ directory
21 @found = findallmod CGI;
22 # set your own search dirs (uses @INC otherwise)
24 setmoduledirs(@INC, @plugindirs, $appdir);
25 # not exported by default
27 use Module::Find qw(ignoresymlinks followsymlinks);
28 # ignore symlinks
30 ignoresymlinks();
31 # follow symlinks (default)
33 followsymlinks();

36 Module::Find lets you find and use modules in categories. This can be
37 very useful for auto-detecting driver or plugin modules. You can
38 differentiate between looking in the category itself or in all
39 subcategories.
40 If you want Module::Find to search in a certain directory on your
42 harddisk (such as the plugins directory of your software installation),
43 make sure you modify @INC before you call the Module::Find functions.
44
46 "setmoduledirs(@directories)"
47 Sets the directories to be searched for modules. If not set,
48 Module::Find will use @INC. If you use this function, @INC will not
49 be included automatically, so add it if you want it. Set to undef
50 to revert to default behaviour.
51 "@found = findsubmod Module::Category"
53 Returns modules found in the Module/Category subdirectories of your
54 perl installation. E.g. "findsubmod CGI" will return
55 "CGI::Session", but not "CGI::Session::File" .
56 "@found = findallmod Module::Category"
58 Returns modules found in the Module/Category subdirectories of your
59 perl installation. E.g. "findallmod CGI" will return "CGI::Session"
60 and also "CGI::Session::File" .
61 "@found = usesub Module::Category"
63 Uses and returns modules found in the Module/Category
64 subdirectories of your perl installation. E.g. "usesub CGI" will
65 return "CGI::Session", but not "CGI::Session::File" .
66 If any module dies during loading, usesub will also die at this
68 point.
69 "@found = useall Module::Category"
71 Uses and returns modules found in the Module/Category
72 subdirectories of your perl installation. E.g. "useall CGI" will
73 return "CGI::Session" and also "CGI::Session::File" .
74 If any module dies during loading, useall will also die at this
76 point.
77 "ignoresymlinks()"
79 Do not follow symlinks. This function is not exported by default.
80 "followsymlinks()"
82 Follow symlinks (default behaviour). This function is not exported
83 by default.

95 use functions. Thanks to Stuart Johnston for alerting me to
96 this and providing a fix.
97 Fixed non-platform compatibility by using File::Spec. Thanks
99 to brian d foy.
100 Added setmoduledirs and updated tests. Idea shamelessly stolen
102 from ...errm... inspired by brian d foy.
103 0.04, 2005-05-20

134 Fixed RT#81077: useall fails in taint mode Thanks to Aran
135 Deltac, who contributed the implementation and test.
136 Fixed RT#83596: Documentation doesn't describe behaviour if a
138 module fails to load Clarified documentation for useall and
139 usesub.
140 Fixed RT#62923: setmoduledirs(undef) doesn't reset to searching
142 @INC Added more explicit tests. Thanks to Colin Robertson for
143 his input.
144 0.13, 2015-03-09
146 This release contains two contributions from Moritz Lenz:
147 Link to Module::Pluggable and Class::Factory::Util in "SEE
149 ALSO"
150 Align package name parsing with how perl does it (allowing
152 single quotes as module separator)
153 Also, added a test for meta.yml
155 0.14, 2019-12-25
157 A long overdue update. Thank you for the many contributions!
158 Fixed RT#99055: Removed file readability check (pull request
160 contributed by Moritz Lenz)
161 Now supports @INC hooks (pull request contributed by Graham
163 Knop)
164 Now filters out filenames starting with a dot (pull request
166 contributed by Desmond Daignault)
167 Now uses strict (pull request contributed by Shlomi Fish)
169 Fixed RT#122016: test/ files show up in metacpan (bug report
171 contributed by Karen Etheridge)
172 0.15, 2019-12-26
174 Fixed RT#127657 (bug report contributed by Karen Etheridge):
175 Module::Find now uses @ModuleDirs (if specified) for loading
176 modules. Previously, when using setmoduledirs() to set an array
177 of directories that did not contain @INC, Module::Find would
178 find the modules correctly, but load them from @INC.
