NAME App::pmpatcher - Apply a set of module patches on your Perl installation VERSION This document describes version 0.06 of App::pmpatcher (from Perl distribution App-pmpatcher), released on 2017-07-07. SYNOPSIS See pmpatcher CLI. DESCRIPTION FUNCTIONS pmpatcher Usage: pmpatcher(%args) -> [status, msg, result, meta] Apply a set of module patches on your Perl installation. You might have a set of patches that you want to apply on Perl modules on all your Perl installation. For example, currently as of this writing I have this on my "patches" directory: pm-OrePAN-Archive-0.08-support_no_index_file.patch pm-Pod-Elemental-PerlMunger-0.200002-DATA_encoding_fix.patch These patches might be pending merge by the module maintainer, or are of private nature so might never be merged, or of any other nature. Applying module patches to an installation is a lightweight alternative to creating a fork for each of these modules. This utility helps you making the process of applying these patches more convenient. Basically this utility just locates all the target modules and feeds all of these patches to the "patch" program. To use this utility, first of all you need to gather all your module patches in a single directory (see "patches_dir" option). Also, you need to make sure that all your "*.patch" files match this name pattern: pm-<MODULE-NAME-DASH-SEPARATED>-<VERSION>-<TOPIC>.patch Then, to apply all the patches, you just call: % pmpatcher --patches-dir ~/patches (Or, you might also want to put "patches_dir=/path/to/patches" into "~/pmpatcher.conf" to save you from having to type the option repeatedly.) Example result: % pmpatcher +--------------------------------------------------------------+--------+---------+ | item_id | status | message | +--------------------------------------------------------------+--------+---------+ | pm-OrePAN-Archive-0.08-support_no_index_file.patch | 200 | Applied | | pm-Pod-Elemental-PerlMunger-0.200002-DATA_encoding_fix.patch | 200 | Applied | +--------------------------------------------------------------+--------+---------+ If you try to run it again, you might get: % pmpatcher +--------------------------------------------------------------+--------+-----------------+ | item_id | status | message | +--------------------------------------------------------------+--------+-----------------+ | pm-OrePAN-Archive-0.08-support_no_index_file.patch | 304 | Already applied | | pm-Pod-Elemental-PerlMunger-0.200002-DATA_encoding_fix.patch | 304 | Already applied | +--------------------------------------------------------------+--------+-----------------+ There's also a "--dry-run" and a "-R" ("--reverse") option, just like "patch". This function is not exported. This function supports dry-run operation. Arguments ('*' denotes required arguments): * patches_dir* => *str* * reverse => *bool* 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 (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) HOMEPAGE Please visit the project's homepage at <https://metacpan.org/release/App-pmpatcher>. SOURCE Source repository is at <https://github.com/perlancar/perl-App-pmpatcher>.
