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. SEE ALSO
