CPAN::Inject - Base class for injecting distributions into CPAN sources
# Create the injector my $cpan = CPAN::Inject->new( sources => '/root/.cpan/sources', # Required field author => 'LOCAL', # The default ); # Add a file to the user $cpan->add( file => 'some/random/Perl-Tarball-1.02.tar.gz' ); # What would have have to use when installing # $path = 'LOCAL/Perl-Tarball-1.02.tar.gz'; my $path = $cpan->install_path( 'some/random/Perl-Tarball-1.02.tar.gz' );
Following the release of CPAN::Mini, the CPAN::Mini::Inject module was created to add additional distributions into a minicpan mirror.
While it was created for use with a minicpan mirror, similar functionality can be reused in other situations.
CPAN::Inject replicates the basics of this functionality.
Specifically, it takes an arbitrary tarball and adds it to the CPAN sources directory for a particular author, and then add the new file to the CHECKSUMS file.
It does not reimplement the logic to add files to the indexes.
The initial use this module was created for was to inject tarballs into the CPAN sources directory for the reserved LOCAL user, so that the can be installed via the CPAN shell, with automated recursion to CPAN dependencies.
But although the number of functions is limited (current only add exists, with the others to be added as needed) the implementation is very generic and sub-classable, so that it can be reused in other situations.
add
# Create the injector for the default LOCAL author $cpan = CPAN::Inject->new( sources => '/root/.cpan/sources', ); # Create the injector for a specific author $cpan = CPAN::Inject->new( sources => '/root/.cpan/sources', author => 'ADAMK', );
The new constructor takes a set of named params and create a cpan injection object.
new
* sources - The compulsory sources param should be the path to a directory that is the root of a mirror (or a partial mirror such as a CPAN::Cache or a CPAN::Mini).
sources
To retain the permissions and ownership integrity of the sources tree, you must be the owner of the sources directory in order to inject the distribution tarballs.
* author - The optional author param should be the CPAN id of an author. By default, the reserved local CPAN id "LOCAL" will be used.
author
The author provided will be used as a default in all further actions.
Returns a CPAN::Inject object, or throws an exception on error.
CPAN::Inject
The from_cpan_config constructor loads the CPAN.pm configuration file, and uses the data contained within to specific the sources path for the object.
from_cpan_config
This constructor is otherwise the same.
Returns a CPAN::Inject object on success, or throws an exception on error.
The sources accessor returns the path to the root of the directory tree.
The author accessor returns the CPAN id for the default author which will be "LOCAL" if you did not provide an alternative param to the the new constructor.
# Add a file to the constructor/default author $cpan->add( file => 'any/arbitrary/Perl-Tarball-1.01.tar.gz' );
The add method takes a Perl distribution tarball from an arbitrary path, and adds it to the sources path.
The specific location the tarball is copied to will be in the root directory for the author provided to the constructor.
Returns the install_path value as a convenience, or throws an exception on error.
# Remove a distribution from the repository $cpan->remove( dist => 'LOCAL/Perl-Tarball-1.01.tar.gz' );
The remove method takes a distribution path and removes it from the sources path. The file is also removed.
remove
Does not return anything useful and throws an exception on error.
# $path = 'authors/id/L/LO/LOCAL' $path = $cpan->author_subpath;
The author_subpath method takes a CPAN author id (or uses the CPAN author id originally provided to the constructor) and returns the relative subpath for the AUTHOR within the sources tree.
author_subpath
Returns the subpath as a string.
# $path = '/root/.cpan/sources/authors/id/L/LO/LOCAL' $path = $cpan->author_subpath;
The author_path method finds the full path for the root directory for the named author.
author_path
Returns the path as a string.
# $path = '/root/.cpan/sources/authors/id/L/LO/LOCAL/Perl-Tarball-1.02.tar.gz' $path = $cpan->file_path( 'Perl-Tarball-1.02.tar.gz' ); $path = $cpan->file_path( '/some/random/place/Perl-Tarball-1.02.tar.gz' );
The file_path method takes the name of a tarball (either just the name or a full path) and calculates the location that the file will end up at.
file_path
When files are copied into the sources directory, they are always copied to the top level of the author root.
# $path = 'LOCAL/Perl-Tarball-1.01.tar.gz'; $path = $cpan->install_path( 'Perl-Tarball-1.01.tar.gz' ); $path = $cpan->install_path( '/some/random/place/Perl-Tarball-1.02.tar.gz' );
The install_path method returns the path for the distribution as the CPAN shell understands it.
install_path
Using this path, the CPAN shell can expand it to locate the distribution, and then can install it.
This module is stored in an Open Repository at the following address.
http://svn.ali.as/cpan/trunk/CPAN-Inject
Write access to the repository is made available automatically to any published CPAN author, and to most other volunteers on request.
If you are able to submit your bug report in the form of new (failing) unit tests, or can apply your fix directly instead of submitting a patch, you are strongly encouraged to do so as the author currently maintains over 100 modules and it can take some time to deal with non-Critcal bug reports or patches.
This will guarentee that your issue will be addressed in the next release of the module.
If you cannot provide a direct test or fix, or don't have time to do so, then regular bug reports are still accepted and appreciated via the CPAN bug tracker.
