NAME

Module::Release - Automate software releases

CONTENTS

SYNOPSIS



        use Module::Release;

        my $release = Module::Release->new( %params );

        # call methods to automate your release process
        $release->check_vcs;
        ...



DESCRIPTION

Module::Release automates your software release process. It started as a script that automated my release process, so it has bits to talk to PAUSE (CPAN) and SourceForge, and to use Makefile.PL and CVS. Other people have extended this in other modules under the same namespace so you can use Module::Build, svn, and many other things.

The methods represent a step in the release process. Some of them check a condition (e.g. all tests pass) and die if that doesn’t work. Module::Release doesn’t let you continue if something is wrong. Once you have checked everything, use the upload features to send your files to the right places.

The included release script is a good starting place. Don’t be afraid to edit it for your own purposes.

    Configuration

Module::Release looks at several sources for configuration information.

Perl setup

Module::Release looks at Config to get the values it needs for certain operations.
make The name of the program to run for the make steps
Environment variables
PERL Use this value as the perl interpreter, otherwise use the value in $^X.
RELEASE_DEBUG Do you want debugging output? Set this to a true value
CPAN_PASS Your CPAN password. If you don’t set this and you want to upload to PAUSE, you should be prompted for it. Failing that, the module tries to upload anonymously but cannot claim the file for you.
.releaserc

Module::Release looks for either .releaserc or releaserc in the current working directory. It reads that with ConfigReader::Simple to get these values:
makefile_PL The name of the file to run as Makefile.PL. The default is "Makefile.PL", but you can set it to "Build.PL" to use a Module::Build-based system.
makefile The name of the file created by makefile_PL above. The default is "Makefile", but you can set it to "Build" for Module::Build-based systems.
cpan_user Your PAUSE user id.
cpan_pass
http_proxy
https_proxy
ignore_prereqs A whitespace separated list of modules for Test::Prereq to ignore.

    Methods

If you don’t like what any of these methods do, override them in a subclass.
new() Create the Module::Release object. It reads the configuration and initializes everything.
init() Set up the Module::Release object. By default, it expects something using MakeMaker, but if it sees a Build.PL it configures itself for Module::Build.

The values in the configuration file override any settings here, so if you have both a Makefile.PL and a Build.PL then you can override the Module::Build preference by setting the makefile_PL and make configuration values.

load_mixin( MODULE ) EXPERIMENTAL!!

Load MODULE through require (so no importing), without caring what it does. My intent is that MODULE adds methods to the Module::Release namespace so a release object can see it. This should probably be some sort of delegation.

Added in 1.21

loaded_mixins Returns a list of the loaded mixins

Added in 1.21

mixin_loaded( MODULE ) Returns true if the mixin class is loaded

    Methods for configuation and settings

config Get the configuration object. By default this is a ConfigReader::Simple object;
local_file( FILENAME ) Returns or sets the name of the local distribution file. You can use the literal argument undef to clear the value.
remote_file Returns the name of the file on the remote side. You can use the literal argument undef to clear the value.

    Methods for multiple perl testing

set_perl Set the current path for the perl binary that Module::Release should use for general tasks. This is not related to the list of perls used to test multiple binaries unless you use one of those binaries to set a new value.

If PATH looks like a perl binary, set_perl uses it as the new setting for perl and returns the previous value.

Added in 1.21.

get_perl Returns the current path for the perl binary that Module::Release should use for general tasks. This is not related to the list of perls used to test multiple binaries.

Added in 1.21.

perls() Return the list of perl binaries Module::Release will use to test the distribution.

Added in 1.21.

add_a_perl( PATH ) Add a perl binary to the list of perls to use for testing. If PATH is not executable or cannot run print $], this method returns nothing and does not add PATH. Otherwise, it returns true. If the same path was already in the list, it returns true but does not create a duplicate.

Added in 1.21.

remove_a_perl( PATH ) Delete PATH from the list of perls used for testing

Added in 1.21.

reset_perls Reset the list of perl interpreters to just the one running release.

Added in 1.21.

output_fh If quiet is off, return the value of output_fh. If output_fh is not set, return STDOUT. If quiet is on, return the value of null_fh.
null_fh Return the null filehandle. So far that’s something set up in new and I haven’t provided a way to set it. Any subclass can make their null_fh return whatever they like.
quiet Get the value of queit mode (true or false).
turn_quiet_on Turn on quiet mode
turn_quiet_off Turn off quiet mode
debug Get the value of the debugging flag (true or false).
turn_debug_on Turn on debugging
turn_debug_off Turn off debugging
debug_fh If debugging is on, return the value of debug_fh. If debug_fh is not set, return STDERR. If debugging is off, return the value of null_fh.

    Methods for building

clean Run ‘make realclean‘
distclean Run ‘make distclean‘
build_makefile() Runs ‘perl Makefile.PL 2>&1‘.

This step ensures that we start off fresh and pick up any changes in Makefile.PL.

make() Run a plain old ‘make‘.
test() Run ‘make test‘. If any tests fail, it dies.
dist() Run ‘make dist‘. As a side effect determines the distribution name if not set on the command line.
disttest Run ‘make disttest‘. If the tests fail, it dies.
dist_test This was the old name for the method, but was inconsistent with other method names. It still works, but is deprecated and will give a warning.
dist_version Return the distribution version ( set in dist() )
dist_version_format Return the distribution version ( set in dist() )

# XXX make this configurable

check_manifest Run ‘make manifest‘ and report anything it finds. If it gives output, die. You should check MANIFEST to ensure it has the things it needs. If files that shouldn’t show up do, put them in MANIFEST.SKIP.

Since ‘make manifest‘ takes care of things for you, you might just have to re-run your release script.

manifest_name Return the name of the manifes file, probably MANIFEST.
manifest This is the old name for manifest_name. It still works but is deprecated.
files_in_manifest Return the filenames in the manifest file as a list.
check_vcs
vcs_tag
make_vcs_tag Note: these methods were formerly cvs, but are now vcs for Version Control System.

This is a placeholder method which should be implemented in a mixin module. Try installing Module::Release::CVS, Module::Release::SVN, or Module::Release::Git and then loading them in your script. The default release script does this for you by checking for the special directories for those source systems.

Previous to version 1.24, these methods were implemented in this module to support CVS. They are now in Module::Release::CVS as a separate module.

touch( FILES ) Set the modification times of each file in FILES to the current time. It tries to open the file for writing and immediately closing it, as well as using utime. It checks that the access and modification times were updated.

Returns the number of files which it successfully touched.

touch_all_in_manifest Runs touch on all of the files in MANIFEST.

    Methods for uploading

should_upload_to_pause Should I upload to PAUSE? If cpan_user and cpan_pass are set, go for it.
check_for_passwords Get passwords for CPAN.
get_readme() Read and parse the README file. This is pretty specific, so you may well want to overload it.
get_changes() Read and parse the Changes file. This is pretty specific, so you may well want to overload it.
run Run a command in the shell.
run_error Returns true if the command ran successfully, and false otherwise. Use this function in any other method that calls run to figure out what to do when a command doesn’t work. You may want to handle that yourself.
get_env_var Get an environment variable or prompt for it

    Methods for developers

_print( LIST ) Send the LIST to whatever is in output_fh, or to STDOUT. If you set output_fh to a null filehandle, output goes nowhere.
_dashes() Use this for a string representing a line in the output. Since it’s a method you can override it if you like.
_debug( LIST ) Send the LIST to whatever is in debug_fh, or to STDERR. If you aren’t debugging, debug_fh should return a null filehandle.
_die( LIST )
_warn( LIST )
