GEM2TGZ(1)GEM2TGZ(1)NAME
gem2tgz - converts Rubygems' .gem file into tarballs
SYNOPSIS
gem2tgz [OPTIONS] GEMNAME [TARBALL] (to download the gem with gem fetch)
gem2tgz [OPTIONS] GEMFILE [TARBALL] (to use a local .gem file)
DESCRIPTION
gem2tgz will convert the .gem file GEM into a tarball named TARBALL. If TARBALL is omitted, gem2tgz will try to guess the filename for the
tarball by taking GEM and replacing '.gem' with '.tar.gz'.

GEM2DEB(1)GEM2DEB(1)NAME
gem2deb - converts Rubygems' .gem file into Debian package
SYNOPSIS
gem2deb [OPTIONS] GEMNAME (to download the gem with gem fetch)
gem2deb [OPTIONS] GEMFILE (to use a local .gem file)
DESCRIPTION
gem2deb converts the gem into a Debian source package, and then will attempt to build it. The process is made of several steps.
First, gem2deb converts the gem file to a tar.gz archive containing a metadata.yml file with the Gem specification. This is equivalent to
what gem2tgz does.
Then, 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 dh-make-ruby does. gem2deb cannot determine all parameters for obvious
reasons. It is recommended to search for the "FIXME" string in the debian/ directory. The generated Debian source package uses dh_ruby to
build the package.
Finally, gem2deb tries to build the source and binary packages using dpkg-buildpackage.
OPTIONS -t, --only-tarball
Stop after creating the tar.gz archive.
-s, --only-source-dir
Stop after preparing the Debian source package directory (do not attempt to build the package).
-S, --only-debian-source
Only build a Debian source package (do not build binary packages).
-p PACKAGE, --package PACKAGE
Specify package name (default: ruby-*). Passed to dh-make-ruby. See dh-make-ruby(1).
--ruby-versions VERSIONS
Ruby versions to build the package for (default: all). Passed to dh-make-ruby. See dh-make-ruby(1).
-h, --help
Displays gem2deb usage information.
-v, --version
Displays gem2deb version information.
HOW THE .GEM ->; .TGZ CONVERSION WORKS
A gem named 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:
Files
It contains all the files the gem contains.
Metadata
It contains the gem metadata ends up in a file named ``metadata.yml`` inside the mygem-0.1.0 directory.
