NAME
extractuse - determine what Perl modules are used in a given file
VERSION
Version 1.0 ($Id: extractuse 6744 2009-04-29 14:32:07Z FREQUENCY@cpan.org $)
SYNOPSIS
Usage: extractuse filename [...]
Given a single path referring to a file containing Perl code, this script will determine the modules included statically. This means that files included by use and require will be retrieved and listed.
DESCRIPTION
This script is safe because the Perl code is never executed, only parsed by Module::Extract::Use or Module::ExtractUse, which are two different implementations of this idea. This module will prefer Module::Extract::Use if it is installed, because it uses PPI to do its parsing, rather than its own separate grammar.
However, one limitation of this script is that only statically included modules can be found - that is, they have to be use'd or require'd at runtime, and not inside an eval string, for example. Because eval strings are completely dynamic, there is no way of determining which modules might be loaded under different conditions.
