NAME
    App::ProveMods - Prove Perl modules' distributions

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

SYNOPSIS
    See the included script prove-mods.

FUNCTIONS
  prove_mods
    Usage:

     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)

    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)
