VERSION

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)
