NAME

Perl::PrereqScanner::Scanner::Perl5 - scan for core Perl 5 language indicators of required modules

VERSION

version 1.009

DESCRIPTION

This scanner will look for the following indicators:

  • plain lines beginning with use or require in your perl modules and scripts, including minimum perl version

  • regular inheritance declared with the base and parent pragmata

Since Perl does not allow you to supply a version requirement with a require statement, the scanner will check the statement after the require Module to see if it is Module->VERSION( minimum_version );.

In order to provide a minimum version, that method call must meet the following requirements:

  • it must be the very next statement after require Module. Nothing can separate them but whitespace and comments (and one semicolon).

  • Module must be a bareword, and match the require exactly.

  • minimum_version must be a literal number, v-string, or single-quoted string. Double quotes are not allowed.
