App::pmpatcher - Apply a set of module patches on your Perl installation
This document describes version 0.06 of App::pmpatcher (from Perl distribution App-pmpatcher), released on 2017-07-07.
See pmpatcher CLI.
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:
patches
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.
patch
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:
patches_dir
*.patch
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.)
patches_dir=/path/to/patches
~/pmpatcher.conf
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.
--dry-run
-R
--reverse
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)
