NAME
dh_ruby - debhelper7 build system for Ruby software SYNOPSIS
dh_ruby [OPTIONS] DESCRIPTION
dh_ruby is a Debhelper 7 build system for Ruby software. It will automatically build and install files contained in Ruby packages, trying to work as close to Rubygems as possible but respecting Debian standards for Ruby packages. dh_ruby can automatically run your tests against all supported Ruby versions, see the "FILES" section below. See dh_ruby --help for details. OPTIONS
--clean, --configure, --build, --test, --install Commands called by debhelper at various steps of the build process. -h, --help Displays dh_ruby usage information. -v, --version Displays dh_ruby version information. --setuprb This option indicates that the build should use setup.rb rather than the usual gem-based build. To take effect, this option must come first ! ENVIRONMENT VARIABLES
DH_RUBY_IGNORE_TESTS This is a space-separated list of tests that dh_ruby will ignore during package build. The available test names are "require-rubygems" plus the names of all supported Ruby versions. At the time of writing, only "ruby1.8" and "ruby1.9.1" are supported. If set to "all", all tests will be ignored during the package build. DH_RUBY_USE_DH_AUTO_INSTALL_DESTDIR If this variable is defined (to anything), dh_ruby will respect the directory informed by dh_auto_install(1), usually debian/tmp. By default, gem2deb will install files to debian/package, where package is the first binary package listed in debian/control. This is useful for multi-binary source packages, where you will have all files installed to debian/tmp, and can them split the files into separate packages by using debian/package.install. DH_RUBY_GEMSPEC Determines which file contain the gem specification with package metadata. By default, dh_ruby will read metadata from a .gemspec file in the root of source package directory. You can use this variable to override that if want to provide custom metadata for the Debian package. In the case there are more than one .gemspec in the source package root, you will need to use DH_RUBY_GEMSPEC to instruct dh_ruby about which one to use. FILES
debian/ruby-test-files.yaml, debian/ruby-tests.rake, debian/ruby-tests.rb Theses files can be used to explicitly tell dh_ruby how to run the tests in your package. When running the tests, dh_ruby will automatically set RUBYLIB to include the appropriate directories where the package files were installed in your package to make sure the tests use them instead of the files in the source directory. Your package can only contain at most one of these files. debian/ruby-test-files.yaml must contain a YAML document with a list of test files to be run. If the package metadata contains an explicit list of test files, gem2deb(1) will automatically generate this file for you. Example from ruby-mime-types: --- - test/test_mime_type.rb - test/test_mime_types.rb debian/ruby-tests.rake can be used to run the tests with rake(1). If you use this file, your package must Build-Depend on the rake package. You can use anything you would use in a regular Rakefile, but you must define a default task. gem2deb includes utility test task that makes it easier for you by creating a default task automatically. Example: require 'gem2deb/rake/testtask' Gem2Deb:Rake::TestTask.new do |t| t.test_files = FileList['test/*_test.rb'] end If debian/ruby-tests.rb exists, it will be run with each supported Ruby version, and must finish with a exit status of 0, otherwise dh_ruby assumes the tests failed. A simple example: require 'test/unit' require 'mypackage' # if 'mypackage.rb' or 'mypackage.so' was not installed properly, this will fail class MyPackageTest < Test::Unit::TestCase def test_features assert_equal 4, MyPackage.sum(2,2) end end debian/require-rubygems.overrides Fine-tune the "require-rubygems" test. If the package has a very good reason to actually `require "rubygems"`, you can use this file as a whitelist of files allowed to have `require "rubygems"`. This file is expect to contain a YAML document with a list of files that must be ignored when checking for `require "rubygems"` lines. Example: --- - debian/ruby-foo/usr/lib/ruby/vendor_ruby/foo.rb - debian/ruby-foo/usr/lib/ruby/vendor_ruby/foo/rubygems.rg As you can see above, you have to list filenames based on their corresponding install locations in the package temporary install directory, i.e. `debian/${pkg}/..` SEE ALSO
