NAME
CPANPLUS::Dist::Build
SYNOPSIS
my $build = CPANPLUS::Dist->new(
format => 'CPANPLUS::Dist::Build',
module => $modobj,
);
$build->prepare; # runs Module::Build->new_from_context;
$build->create; # runs build && build test
$build->install; # runs build install
DESCRIPTION
CPANPLUS::Dist::Build
is a distribution class for Module::Build
related modules. Using this package, you can create, install and uninstall perl modules. It inherits from CPANPLUS::Dist
.
Normal users won't have to worry about the interface to this module, as it functions transparently as a plug-in to CPANPLUS
and will just Do The Right Thing
when it's loaded.
ACCESSORS
- parent()
-
Returns the
CPANPLUS::Module
object that parented this object. - status()
-
Returns the
Object::Accessor
object that keeps the status for this module.
STATUS ACCESSORS
All accessors can be accessed as follows: $build->status->ACCESSOR
- build_pl ()
-
Location of the Build file. Set to 0 explicitly if something went wrong.
- build ()
-
BOOL indicating if the
Build
command was successful. - test ()
-
BOOL indicating if the
Build test
command was successful. - prepared ()
-
BOOL indicating if the
prepare
call exited succesfully This gets set afterperl Build.PL
- distdir ()
-
Full path to the directory in which the
prepare
call took place, set after a call toprepare
. - created ()
-
BOOL indicating if the
create
call exited succesfully. This gets set afterBuild
andBuild test
. - installed ()
-
BOOL indicating if the module was installed. This gets set after
Build install
exits successfully. - uninstalled ()
-
BOOL indicating if the module was uninstalled properly.
- _create_args ()
-
Storage of the arguments passed to
create
for this object. Used for recursive calls when satisfying prerequisites. - _install_args ()
-
Storage of the arguments passed to
install
for this object. Used for recursive calls when satisfying prerequisites. - _mb_object ()
-
Storage of the
Module::Build
object we used for this installation.
METHODS
$bool = CPANPLUS::Dist::Build->format_available();
Returns a boolean indicating whether or not you can use this package to create and install modules in your environment.
$bool = $dist->init();
Sets up the CPANPLUS::Dist::Build
object for use. Effectively creates all the needed status accessors.
Called automatically whenever you create a new CPANPLUS::Dist
object.
$bool = $dist->prepare([perl => '/path/to/perl', buildflags => 'EXTRA=FLAGS', force => BOOL, verbose => BOOL])
prepare
prepares a distribution, running Module::Build
's new_from_context
method, and establishing any prerequisites this distribution has.
After a succcesfull prepare
you may call create
to create the distribution, followed by install
to actually install it.
Returns true on success and false on failure.
$dist->create([perl => '/path/to/perl', buildflags => 'EXTRA=FLAGS', prereq_target => TARGET, force => BOOL, verbose => BOOL, skiptest => BOOL])
create
preps a distribution for installation. This means it will run Build
and Build test
, via the Module::Build
API. This will also satisfy any prerequisites the module may have.
If you set skiptest
to true, it will skip the Build test
stage. If you set force
to true, it will go over all the stages of the Build
process again, ignoring any previously cached results. It will also ignore a bad return value from Build test
and still allow the operation to return true.
Returns true on success and false on failure.
You may then call $dist->install
on the object to actually install it.
$dist->install([verbose => BOOL, perl => /path/to/perl])
Actually installs the created dist.
Returns true on success and false on failure.
KNOWN ISSUES
Below are some of the known issues with Module::Build, that we hope the authors will resolve at some point, so we can make full use of Module::Build's power. The number listed is the bug number on rt.cpan.org
.
Uninstall modules installed by Module::Build (#13308)
Module::Build doesn't write a so called
packlist
file, which holds a list of all files installed by a distribution. Without this file we don't know what to remove. Until Module::Build generates thispacklist
, we are unable to remove any installations done by it.Module::Build's version comparison is not supported.
Module::Build has its own way of defining what versions are considered satisfactory for a prerequisite, and which ones aren't. This syntax is something specific to Module::Build and we currently have no way to see if a module on disk, on cpan or something similar is satisfactory according to Module::Build's version comparison scheme. As a work around, we now simply assume that the most recent version on CPAN satisfies a dependency.
Module::Build doesn't support 'PREFIX' (#8759)
Module::Build doens't support the standard
Makefile.PL
argumentPREFIX
and dies if it is provided. Even though that's not usually a problem, sometimes M::B enabled distros ship aMakefile.PL
that calls theBuild.PL
under the hood. In these cases, aPREFIX
might be provided andModule::Build
will die.Module::Build masquerades as Makefile.PL but is not compatible (#13145)
Related to the previous entry,
Module::Build
can create aMakefile.PL
which under the hood invokesModule::Build
. It however does not support all the options thatExtUtils::MakeMaker
does, and will die if you try to invoke the file with one of those options.Module::Build can not be upgraded using it's own API (#13169)
This is due to the fact that the Build file insists on adding a path to
@INC
which force the loading of thenot yet installed
Module::Build when it shells out to run it's own build procedure:Module::Build does not provide access to install history (#9793)
Module::Build
runs the create, test and install procedures in it's own processes, but does not provide access to any diagnostic messages of those processes. As an end result, we can not offer these diagnostic messages when, for example, reporting automated build failures to sites liketesters.cpan.org
.
