NAME

ruby-fakegem.eclass - An eclass for installing Ruby packages to behave like RubyGems.

DESCRIPTION

This eclass allows to install arbitrary Ruby libraries (including Gems), providing integration into the RubyGems system even for "regular" packages.

SUPPORTED EAPIS

TRANSITIVELY PROVIDED ECLASSES

FUNCTIONS

ruby_fakegem_gemsdir: This function returns the gems data directory for the ruby implementation in question.
Return value: Returns the gem data directory
ruby_fakegem_doins <file> [file...]: Installs the specified file(s) into the gems directory.
ruby_fakegem_newins <file> <newname>: Installs the specified file into the gems directory using the provided filename.
ruby_fakegem_install_gemspec: Install a .gemspec file for this package. Either use the file indicated by the RUBY_FAKEGEM_GEMSPEC variable, or generate one using ruby_fakegem_genspec.
ruby_fakegem_gemspec_gemspec <gemspec-input> <gemspec-output>: Generates an installable version of the specification indicated by RUBY_FAKEGEM_GEMSPEC. This file is eval'ed to produce a final specification in a way similar to packaging the gemspec file.
ruby_fakegem_metadata_gemspec <gemspec-metadata> <gemspec-output>: Generates an installable version of the specification indicated by the metadata distributed by the gem itself. This is similar to how rubygems creates an installation from a .gem file.
ruby_fakegem_genspec <output-gemspec>: Generates a gemspec for the package and places it into the "specifications" directory of RubyGems. If the metadata normally distributed with a gem is present then that is used to generate the gemspec file.
As a fallback we can generate our own version. In the gemspec, the following values are set: name, version, summary, homepage, and require_paths=["lib"]. See RUBY_FAKEGEM_NAME and RUBY_FAKEGEM_VERSION for setting name and version. See RUBY_FAKEGEM_REQUIRE_PATHS for setting extra require paths.
ruby_fakegem_binwrapper <command> [path] [content]: Creates a new binary wrapper for a command installed by the RubyGem. path defaults to /usr/bin/$command content is optional and can be used to inject additional ruby code into the wrapper. This may be useful to e.g. force a specific version using the gem command.
each_fakegem_configure: Configure extensions defined in RUBY_FAKEGEM_EXTENSIONS, if any.
each_ruby_configure: Run each_fakegem_configure for each ruby target
all_fakegem_compile: Build documentation for the package if indicated by the doc USE flag and if there is a documentation task defined.
each_fakegem_compile: Compile extensions defined in RUBY_FAKEGEM_EXTENSIONS, if any.
each_ruby_compile: Run each_fakegem_compile for each ruby target
all_ruby_unpack: Unpack the source archive, including support for unpacking gems.
all_ruby_compile: Compile the package.
each_fakegem_test: Run tests for the package for each ruby target if the test task is defined.
each_ruby_test: Run the tests for this package.
ruby_fakegem_extensions_installed: Install the marker indicating that extensions have been installed. This is normally done as part of the extension installation, but may be useful when we handle extensions manually.
ruby_fakegem_extensionsdir: The directory where rubygems expects extensions for this package version.
each_fakegem_install: Install the package for each ruby target.
each_ruby_install: Install the package for each target.
all_fakegem_install: Install files common to all ruby targets.
all_ruby_install: Install files common to all ruby targets.

ECLASS VARIABLES

RUBY_FAKEGEM_NAME = "${RUBY_FAKEGEM_NAME:-${PN}}" (SET BEFORE INHERIT): Sets the Gem name for the generated fake gemspec. This variable MUST be set before inheriting the eclass.
RUBY_FAKEGEM_VERSION = "${RUBY_FAKEGEM_VERSION:-${PV/_pre/.pre}}" (SET BEFORE INHERIT): Sets the Gem version for the generated fake gemspec. This variable MUST be set before inheriting the eclass.
RUBY_FAKEGEM_TASK_DOC = "${RUBY_FAKEGEM_TASK_DOC-rdoc}": Specify the rake(1) task to run to generate documentation.
RUBY_FAKEGEM_RECIPE_TEST = "${RUBY_FAKEGEM_RECIPE_TEST-rake}": Specify one of the default testing function for ruby-fakegem:
- rake (default; see also RUBY_FAKEGEM_TASK_TEST)
- rspec (calls ruby-ng_rspec, adds dev-ruby/rspec:2 to the dependencies)
- rspec3 (calls ruby-ng_rspec, adds dev-ruby/rspec:3 to the dependencies)
- cucumber (calls ruby-ng_cucumber, adds dev-util/cucumber to the
dependencies)
- sus (calls ruby-ng_sus, adds dev-ruby/sus to the dependencies)
- none
RUBY_FAKEGEM_TASK_TEST = "${RUBY_FAKEGEM_TASK_TEST-test}": Specify the rake(1) task used for executing tests. Only valid if RUBY_FAKEGEM_RECIPE_TEST is set to "rake" (the default).
RUBY_FAKEGEM_RECIPE_DOC = rdoc}": Specify one of the default API doc building function for ruby-fakegem:
- rake (default; see also RUBY_FAKEGEM_TASK_DOC)
- rdoc (calls `rdoc-2`, adds dev-ruby/rdoc to the dependencies);
- yard (calls `yard`, adds dev-ruby/yard to the dependencies);
- none
RUBY_FAKEGEM_DOCDIR: Specify the directory under which the documentation is built; if empty no documentation will be installed automatically. Note: if RUBY_FAKEGEM_RECIPE_DOC is set to `rdoc`, this variable is hardwired to `doc`.
RUBY_FAKEGEM_EXTRADOC: Extra documentation to install (readme, changelogs, …).
RUBY_FAKEGEM_DOC_SOURCES = "${RUBY_FAKEGEM_DOC_SOURCES-lib}": Allow settings defined sources to scan for documentation. This only applies if RUBY_FAKEGEM_DOC_TASK is set to `rdoc`.
RUBY_FAKEGEM_BINWRAP = "${RUBY_FAKEGEM_BINWRAP-*}": Binaries to wrap around (relative to the RUBY_FAKEGEM_BINDIR directory)
RUBY_FAKEGEM_BINDIR = "${RUBY_FAKEGEM_BINDIR-bin}": Path that contains binaries to be binwrapped. Equivalent to the gemspec bindir option.
RUBY_FAKEGEM_REQUIRE_PATHS: Extra require paths (beside lib) to add to the specification
RUBY_FAKEGEM_GEMSPEC: Filename of .gemspec file to install instead of generating a generic one.
RUBY_FAKEGEM_EXTRAINSTALL: List of files and directories relative to the top directory that also get installed. Some gems provide extra files such as version information, Rails generators, or data that needs to be installed as well.
RUBY_FAKEGEM_EXTENSIONS: List of extensions supported by this gem. Each extension is listed as the configuration script that needs to be run to generate the extension.
RUBY_FAKEGEM_EXTENSION_OPTIONS: Additional options that are passed when configuring the extension. Some extensions use this to locate paths or turn specific parts of the extionsion on or off.
RUBY_FAKEGEM_EXTENSION_LIBDIR = "${RUBY_FAKEGEM_EXTENSION_LIBDIR-lib}": The lib directory where extensions are copied directly after they have been compiled. This is needed to run tests on the code and was the legacy way to install extensions for a long time.
