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" . "@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" . "ignoresymlinks()" Do not follow symlinks. This function is not exported by default. "followsymlinks()" Follow symlinks (default behaviour). This function is not exported by default. HISTORY
