NAME

Devel::PatchPerl - Patch perl source a la Devel::PPPort's buildperl.pl

VERSION

version 2.09

SYNOPSIS

use strict;
use warnings;

use Devel::PatchPerl;

Devel::PatchPerl->patch_source( '5.6.1', '/path/to/untarred/perl/source/perl-5.6.1' );

DESCRIPTION

Devel::PatchPerl is a modularisation of the patching code contained in Devel::PPPort's buildperl.pl.

It does not build perls, it merely provides an interface to the source patching functionality.

FUNCTION

patch_source

Takes two parameters, a perl version and the path to unwrapped perl source for that version. It dies on any errors.

If you don't supply a perl version, it will attempt to auto-determine the perl version from the specified path.

If you don't supply the path to unwrapped perl source, it will assume the current working directory.

determine_version

Takes one optional parameter, the path to unwrapped perl source. It returns the perl version of the source code at the given location. It returns undef on error.

If you don't supply the path to unwrapped perl source, it will assume the current working directory.

PLUGIN SYSTEM

See Devel::PatchPerl::Plugin for details of Devel::PatchPerl's plugin system.

PATCHLEVEL

Devel::PatchPerl will normally update the patchlevel.h file in the perl source tree to indicate that it has applied local patches. This behaviour is negated if it is detected that it is operating in a git repository. To override this and update patchlevel.h when in a Git repository, set the env var PERL5_PATCHPERL_PATCHLEVEL to a true value.

Alternatively, call patchperl with the --patchlevel option.

CAVEAT

Devel::PatchPerl is intended only to facilitate the building of perls, not to facilitate the testing of perls. This means that it will not patch failing tests in the perl testsuite.
