App::ProveMods - Prove Perl modules' distributions


This document describes version 0.001 of App::ProveMods (from Perl distribution App-ProveMods), released on 2020-03-07.


See the included script prove-mods.




 prove_mods(%args) -> [status, msg, payload, meta]

Prove Perl modules' distributions.

To use this utility, first create ~/.config/prove-mods.conf:

 dists_dirs = ~/repos
 dists_dirs = ~/repos-other

The above tells prove-mods where to look for Perl distributions. Then:

 % prove-mods '^Regexp::Pattern.*'

This will search local CPAN mirror for all modules that match that regex pattern, then search the distributions in the distribution directories (or download them from local CPAN mirror), cd to each and run prove in it.

You can run with --dry-run (-n) option first to not actually run prove but just see what distributions will get tested. An example output:

 % prove-mods '^Regexp::Pattern' -n
 prove-mods: Found module: Regexp::Pattern (dist=Regexp-Pattern)
 prove-mods: Found module: Regexp::Pattern::CPAN (dist=Regexp-Pattern-CPAN)

The above example shows that I have the distribution directories locally on my ~/repos, except for one 'Regexp::Pattern::License'.

If we reinvoke the above command without the -n, prove-rdeps will actually run prove on each directory and provide a summary at the end. Example output:

 % prove-mods '^Regexp::Pattern'
 | dir                                           | label                               | reason                            | status |
 | /tmp/2GOBZuxird/Regexp-Pattern-License-v3.2.0 | distribution Regexp-Pattern-License | Test failed (Failed 1/2 subtests) | 500    |

The above example shows that one distribution failed testing. You can scroll up for the detailed prove output to see the details of failure failed, fix things, and re-run.

How distribution directory is searched: see App::ProveDists documentation.

When a dependent distribution cannot be found or downloaded/extracted, this counts as a 412 error (Precondition Failed).

When a distribution's test fails, this counts as a 500 error (Error). Otherwise, the status is 200 (OK).

prove-rdeps will return status 200 (OK) with the status of each dist. It will exit 0 if all distros are successful, otherwise it will exit 1.

This function is not exported.

This function supports dry-run operation.

Arguments ('*' denotes required arguments):

  • dists_dirs* => array[dirname]

    Where to find the distributions directories.

  • download => bool (default: 1)

    Whether to try download/extract distribution from local CPAN mirror (when not found in dists_dirs).

  • modules* => array[re]

    Module names to prove.

  • prove_opts => array[str] (default: ["-l"])

    Options to pass to the prove command.

  • summarize_all => bool

    If true, also summarize successes in addition to failures.

Special arguments:

  • -dry_run => bool

    Pass -dry_run=>1 to enable simulation mode.

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 (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
