ada.eclass

Name

ada.eclass -- An eclass for Ada packages

Description

This eclass set the IUSE and REQUIRED_USE to request the ADA_TARGET when the inheriting ebuild can be supported by more than one Ada implementation. It also set ADA_USEDEP and ADA_DEPS with a suitable form. A common eclass providing helper functions to build and install packages supporting Ada implementations.

This eclass sets correct IUSE. Modification of REQUIRED_USE has to be done by the author of the ebuild (but ADA_REQUIRED_USE is provided for convenience, see below). ada exports ADA_DEPS and ADA_USEDEP so you can create correct dependencies for your package easily.

Mostly copied from python-single-r1.eclass

Functions

ada_export [<impl>] <variables>...

Set and export the Ada implementation-relevant variables passed as parameters.

The optional first parameter may specify the requested Ada implementation (either as ADA_TARGETS value, e.g. ada2_7, or an EADA one, e.g. ada2.7). If no implementation passed, the current one will be obtained from ${EADA}.

The variables which can be exported are: GCC, EADA, GNATMAKE. They are described more completely in the eclass variable documentation.

ada_wrapper_setup [<path> [<impl>]]

Create proper 'ada' executable wrappers in the directory named by <path>. Set up PATH appropriately. <path> defaults to ${T}/${EADA}.

The wrappers will be created for implementation named by <impl>, or for one named by ${EADA} if no <impl> passed.

If the named directory contains a ada symlink already, it will be assumed to contain proper wrappers already and only environment setup will be done. If wrapper update is requested, the directory shall be removed first.

ada_setup

Determine what the selected Ada implementation is and set the Ada build environment up for it.

ada_pkg_setup

Runs ada_setup.

Variables

ADA_DEPS (GENERATED BY ECLASS)

This is an eclass-generated Ada dependency string for all implementations listed in ADA_COMPAT.

The dependency string is conditional on ADA_TARGET.

Example use:

RDEPEND="${ADA_DEPS}
  dev-foo/mydep"
DEPEND="${RDEPEND}"
