=head1 NAME
|
|
|
|
gem2deb - converts Rubygems' .gem file into Debian package
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<gem2deb> [I<OPTIONS>] I<GEMNAME> (to download the gem with I<gem fetch>)
|
|
|
|
B<gem2deb> [I<OPTIONS>] I<GEMFILE> (to use a local .gem file)
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<gem2deb> converts the gem into a Debian source package, and then will attempt
|
|
to build it. The process is made of several steps.
|
|
|
|
First, B<gem2deb> converts the gem file to a tar.gz archive containing a
|
|
metadata.yml file with the Gem specification. This is equivalent to what
|
|
B<gem2tgz> does.
|
|
|
|
Then, B<gem2deb> unpacks the tar.gz archive and prepares a Debian source
|
|
package, guess many of the defaults from the files included in the archive, or
|
|
the Gem specification. This is equivalent to what B<dh-make-ruby> does.
|
|
B<gem2deb> cannot determine all parameters for obvious reasons. It is recommended
|
|
to search for the "FIXME" string in the I<debian/> directory.
|
|
The generated Debian source package uses B<dh_ruby> to build the package.
|
|
|
|
Finally, B<gem2deb> tries to build the source and binary packages using
|
|
B<dpkg-buildpackage>.

=head1 HOW THE .GEM -> .TGZ CONVERSION WORKS
|
|
|
|
A gem named I<mygem-0.1.0.gem> is converted in a tarball with
|
|
(approximately) the following steps:
|
|
|
|
mkdir mygem-0.1.0
|
|
cd mygem-0.1.0
|
|
tar xfm /absolute/path/to/mygem-0.1.0.gem
|
|
tar xzfm data.tar.gz
|
|
zcat metadata.gz > metadata.yml
|
|
rm -f data.tar.gz metadata.gz
|
|
cd ..
|
|
tar czf mygem-0.1.0.tar.gz mygem-0.1.0
|
|
rm -rf mygem-0.1.0
|
|
|
|
The generated tarball has the following properties:
|
|
|
|
=over
|
|
|
|
=item Files
|
|
|
|
It contains all the files the gem contains.
|
|
|
|
=item Metadata
|
|
|
|
It contains the gem metadata ends up in a file named ``metadata.yml`` inside
|
|
the I<mygem-0.1.0> directory.
