NAME
Module::Extract::Use - Pull out the modules a module uses
SYNOPSIS
use Module::Extract::Use;
my $extor = Module::Extract::Use->new;
my @modules = $extor->get_modules( $file );
if( $extor->error ) { ... }
DESCRIPTION
Extract the names of the modules used in a file using a static analysis. Since this module does not run code, it cannot find dynamic uses of modules, such as eval "require $class".
- new
-
Makes an object. The object doesn't do anything just yet, but you need it to call the methods.
- init
-
Set up the object. You shouldn't need to call this yourself.
- get_modules( FILE )
-
Returns a list of namespaces explicity use-d in FILE. Returns undef if the file does not exist or if it can't parse the file.
Each used namespace is only in the list even if it is used multiple times in the file. The order of the list does not correspond to anything so don't use the order to infer anything.
- error
-
Return the error from the last call to
get_modules.
TO DO
* Make it recursive, so it scans the source for any module that it finds.
