NAME ^

Module::Find - Find and use installed modules in a (sub)category

SYNOPSIS ^

  use Module::Find;

  # use all modules in the Plugins/ directory
  @found = usesub Mysoft::Plugins;

  # use modules in all subdirectories
  @found = useall Mysoft::Plugins;

  # find all DBI::... modules
  @found = findsubmod DBI;

  # find anything in the CGI/ directory
  @found = findallmod CGI;
  
  # set your own search dirs (uses @INC otherwise)
  setmoduledirs(@INC, @plugindirs, $appdir);
  
  # not exported by default
  use Module::Find qw(ignoresymlinks followsymlinks);
  
  # ignore symlinks
  ignoresymlinks();
  
  # follow symlinks (default)
  followsymlinks();

DESCRIPTION ^

Module::Find lets you find and use modules in categories. This can be very useful for auto-detecting driver or plugin modules. You can differentiate between looking in the category itself or in all subcategories.

If you want Module::Find to search in a certain directory on your harddisk (such as the plugins directory of your software installation), make sure you modify @INC before you call the Module::Find functions.

FUNCTIONS ^

setmoduledirs(@directories)

Sets the directories to be searched for modules. If not set, Module::Find will use @INC. If you use this function, @INC will not be included automatically, so add it if you want it. Set to undef to revert to default behaviour.

@found = findsubmod Module::Category

Returns modules found in the Module/Category subdirectories of your perl installation. E.g. findsubmod CGI will return CGI::Session, but not CGI::Session::File .

@found = findallmod Module::Category

Returns modules found in the Module/Category subdirectories of your perl installation. E.g. findallmod CGI will return CGI::Session and also CGI::Session::File .

@found = usesub Module::Category

Uses and returns modules found in the Module/Category subdirectories of your perl installation. E.g. usesub CGI will return CGI::Session, but not CGI::Session::File .

If any module dies during loading, usesub will also die at this point.

@found = useall Module::Category

Uses and returns modules found in the Module/Category subdirectories of your perl installation. E.g. useall CGI will return CGI::Session and also CGI::Session::File .

If any module dies during loading, useall will also die at this point.

ignoresymlinks()

Do not follow symlinks. This function is not exported by default.

followsymlinks()

Follow symlinks (default behaviour). This function is not exported by default.
