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);

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" .
"@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" .
