NAME

cpangitify - Convert cpan distribution from BackPAN to a git repository

VERSION

version 0.20

SYNOPSIS

 % cpangitify Foo::Bar

DESCRIPTION

This script fetches all known revisions of a distribution from CPAN/BackPAN and creates a git repository with one revision and one tag for each version of the distribution.

The idea is to create a starting point for a git work flow when adopting a CPAN module for which you don't have access to the original repository. It is of course better to import from Subversion or to clone an existing git repository, but that may not be an option.

If the distribution you are migrating changed names during its history, simply specify each name it had on the command line. Be sure to specify the current name first (this will be used when creating a directory name for the repository). For example Mojolicious::Plugin::TtRenderer was once called MojoX::Renderer::TT, so you would get both names in the history like this:

 % cpangitify Mojolicious::Plugin::TtRenderer MojoX::Renderer::TT

OPTIONS

--resume

Resume the import from CPAN. Note that any local changes will be overwritten by the CPAN upstream (your modifications will remain in the repository history).

--output | -o directory

Creat the new repository in the given directory.

--skip version

Skip the given versions. Can be specified multiple times and can be provided as a comma separated list.

--trace

Print each git command before it is executed.

--backpan_index_url

The URL to use for the BackPAN index

--backpan_url

The URL to use for BackPAN

--metacpan_url

The URL to use for metacpan.

--branch | -b

Default branch. As on 0.18 this is main by default. Previously the old git default was used.

--help | -h

Print out help and exit.

--version

Print out version and exit.

CAVEATS

Each commit belongs to the CPAN author who submitted the corresponding release, therefore git blame may not be that useful for the imported portion of your new repository history.

The commits are ordered by date, so where there are interleaving of releases that belong to development and production branches this simple minded script will probably do the wrong thing.

Patches are welcome.

SEE ALSO

Here are some similar projects:

The reason I am not using the latter two is that they are designed to mirror the whole of CPAN/BackPAN, but I'm mostly just interested in one or two distributions here and there.
