App::LintPrereqs - Check extraneous/missing prerequisites in dist.ini


This document describes version 0.31 of App::LintPrereqs (from Perl distribution App-LintPrereqs), released on 2015-08-31.


 # Use via lint-prereqs CLI script


lint_prereqs(%args) -> [status, msg, result, meta]

{en_US Check extraneous/missing prerequisites in dist.ini}.

{en_US Check [Prereqs / *] (as well as OSPrereqs, Extras/lint-prereqs/Assume-*) sections in your dist.ini against what's actually being used in your Perl code (using Perl::PrereqScanner::Lite) and what's in Perl core list of modules. Will complain if your prerequisites are not actually used, or already in Perl core. Will also complain if there are missing prerequisites.

Designed to work with prerequisites that are manually written. Does not work if you use AutoPrereqs.

Sometimes there are prerequisites that you know are used but can't be detected by scan_prereqs, or you want to include anyway. If this is the case, you can instruct lint_prereqs to assume the prerequisite is used.

 ;!lint-prereqs assume-used # even though we know it is not currently used
 ;!lint-prereqs assume-used # we are forcing a certain version

Sometimes there are also prerequisites that are detected by scan_prereqs, but you know are already provided by some other modules. So to make lint-prereqs ignore them:

 [Extras / lint-prereqs / assume-provided]


Arguments ('*' denotes required arguments):

  • lite => bool (default: 1)

    {en_US Use Perl::PrereqScanner::Lite instead of Perl::PrereqScanner}.

    {en_US Lite is faster but it might still miss detecting some modules. }

  • perl_version => str

    {en_US Perl version to use (overrides scan_prereqs/dist.ini)}.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
