# @BLURB: Eclass for Qt4-based packages, second edition.
# @DESCRIPTION:
# This eclass contains various functions that may be useful when
# dealing with packages using Qt4 libraries. Supports only EAPIs
# 2, 3, 4, and 5. Use qmake-utils.eclass in EAPI 6 and later.

# @ECLASS-VARIABLE: DOCS
# @DEFAULT_UNSET
# @DESCRIPTION:
# Array containing documents passed to dodoc command.
# Paths can be absolute or relative to ${S}.
#
# Example: DOCS=( ChangeLog README "${WORKDIR}/doc_folder/" )

# @ECLASS-VARIABLE: HTML_DOCS
# @DEFAULT_UNSET
# @DESCRIPTION:
# Array containing documents passed to dohtml command.
# Paths can be absolute or relative to ${S}.
#
# Example: HTML_DOCS=( "doc/document.html" "${WORKDIR}/html_folder/" )

# @ECLASS-VARIABLE: LANGS
# @DEFAULT_UNSET
# @DESCRIPTION:
# In case your Qt4 application provides various translations, use this variable
# to specify them in order to populate "linguas_*" IUSE automatically. Make sure
# that you set this variable before inheriting qt4-r2 eclass.
#
# Example: LANGS="de el it ja"
for x in ${LANGS}; do
	IUSE+=" linguas_${x}"
done

# @ECLASS-VARIABLE: LANGSLONG
# @DEFAULT_UNSET
# @DESCRIPTION:
# Same as LANGS, but this variable is for LINGUAS that must be in long format.
# Remember to set this variable before inheriting qt4-r2 eclass.
# Look at ${PORTDIR}/profiles/desc/linguas.desc for details.
#
# Example: LANGSLONG="en_GB ru_RU"
for x in ${LANGSLONG}; do
	IUSE+=" linguas_${x%_*}"
done

# @ECLASS-VARIABLE: PATCHES
# @DEFAULT_UNSET
# @DESCRIPTION:
# Array variable containing all the patches to be applied. This variable
# is expected to be defined in the global scope of ebuilds. Make sure to
# specify the full path. This variable is used in src_prepare phase.
#
# Example:
# @CODE
# PATCHES=(
# 	"${FILESDIR}/mypatch.patch"
# 	"${FILESDIR}/mypatch2.patch"
# )
# @CODE
