App::LintPrereqs - Check extraneous/missing/incorrect prerequisites in dist.ini
This document describes version 0.41 of App::LintPrereqs (from Perl distribution App-LintPrereqs), released on 2016-03-17.
# Use via lint-prereqs CLI script
lint_prereqs(%args) -> [status, msg, result, meta]
Check extraneous/missing/incorrect prerequisites in dist.ini.
lint-prereqs can improve your prereqs specification in
dist.ini by reporting prereqs that are extraneous (specified but unused), missing (used/required but not specified), or incorrect (mismatching version between what's specified in
dist.ini vs in source code, incorrect phase like test prereqs specified in runtime, etc).
Checking actual usage of prereqs is done using
Sections that will be checked for prereqs include
[Prereqs / *], as well as
Extras/lint-prereqs/Assume-*. Designed to work with prerequisites that are manually written. Does not work if you use AutoPrereqs (using AutoPrereqs basically means that you do not specify prereqs and just use whatever modules are detected by the scanner.)
Sometimes there are prerequisites that you know are used but can't be detected by the scanner, or you want to include anyway. If this is the case, you can instruct lint_prereqs to assume that the prerequisite is used.
;!lint_prereqs assume-used "even though we know it is not currently used" Foo::Bar=0 ;!lint_prereqs assume-used "we are forcing a certain version" Baz=0.12
Sometimes there are also prerequisites that are detected by scan_prereqs, but are false positives (
Perl::PrereqScanner::Lite sometimes does this because its parser is simpler) or you know are already provided by some other modules. So to make lint-prereqs ignore them:
[Extras / lint-prereqs / assume-provided] Qux::Quux=0
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
core_prereqs => bool (default: 1)
Whether or not prereqs to core modules are allowed.
If set to 0 (the default), will complain if there are prerequisites to core modules. If set to 1, prerequisites to core modules are required just like other modules.
fix => bool
Attempt to automatically fix the errors.
lint-prereqscan attempt to automatically fix the errors by adding/removing/moving prereqs in
dist.ini. Not all errors can be automatically fixed. When modifying
dist.ini, a backup in
dist.ini~will be created.
lite => bool (default: 0)
Use Perl::PrereqScanner::Lite instead of Perl::PrereqScanner.
Lite is faster but it might still miss detecting some modules.
perl_version => str
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)
