NAME

vala.eclass - Sets up the environment for using a specific version of vala.

DESCRIPTION

This eclass sets up commonly used environment variables for using a specific version of dev-lang/vala to configure and build a package. It is needed for packages whose build systems assume the existence of certain unversioned vala executables, pkgconfig files, etc., which Gentoo does not provide.

This eclass provides one phase function: src_prepare.

FUNCTIONS

vala_api_versions: Outputs a list of vala API versions from VALA_MAX_API_VERSION down to VALA_MIN_API_VERSION.
vala_depend: Outputs a ||-dependency string on vala from VALA_MAX_API_VERSION down to VALA_MIN_API_VERSION
vala_best_api_version: Returns the highest installed vala API version satisfying VALA_MAX_API_VERSION, VALA_MIN_API_VERSION, and VALA_USE_DEPEND.
vala_src_prepare [--ignore-use] [--vala-api-version api_version]: Sets up the environment variables and pkgconfig files for the specified API version, or, if no version is specified, for the highest installed vala API version satisfying VALA_MAX_API_VERSION, VALA_MIN_API_VERSION, and VALA_USE_DEPEND. Is a no-op if called without --ignore-use when USE=-vala. Dies if the USE check is passed (or ignored) and a suitable vala version is not available.

ECLASS VARIABLES

VALA_MIN_API_VERSION = ${VALA_MIN_API_VERSION:-0.10}: Minimum vala API version (e.g. 0.16).
VALA_MAX_API_VERSION = ${VALA_MAX_API_VERSION:-0.20}: Maximum vala API version (e.g. 0.18).
VALA_USE_DEPEND: USE dependencies that vala must be built with (e.g. vapigen).
