NAME Alien::patch - Find or build patch VERSION version 0.15 SYNOPSIS use Alien::patch (); use Env qw( @PATH ); unshift @PATH, Alien::patch->bin_dir; my $patch = Alien::patch->exe; system "$patch -p1 < foo.patch"; Or in your alienfile: use alienfile; ... share { ... # Alien-Build knows to automatically pull in Alien::patch # so you do not need to specify it as a prereq. # The %{.install.patch} directory is a shortcut for the # `patch' directory in your dist, and gets copied into the # dist share directory, so you can rebuild with `af' after # install. patch [ '%{patch} -p1 < %{.install.patch}/mypatch.patch' ]; }; Or with Alien::Build::ModuleBuild: use Alien::Base::ModuleBuild; Alien::Base::ModuleBuild->new( ... alien_bin_requires => { 'Alien::patch' => '0.08', }, alien_build_commands => { '%{patch} -p1 < foo.patch', }, ... )->create_build_script; DESCRIPTION Many environments provide the patch command, but a few do not. Using this module in your alienfile (or elsewhere) you can make sure that patch will be available. If the system provides it, then great, this module is a no-op. If it does not, then it will download and install it into a private location so that it can be added to the PATH when this module is used. This class is a subclass of Alien::Base, and works closely with Alien::Build and alienfile METHODS exe my $exe = Alien::patch->exe; Returns the command to run patch on your system. For now it simply adds the --binary option on Windows (MSWin32 but not cygwin) which is usually what you want. HELPERS patch %{patch} When used with Alien::Base::ModuleBuild in a alien_build_commands or alien_install_commands, this helper will be replaced by either patch (Unix and cygwin) or patch --binary (MSWin32).
