# @ECLASS: clojure.eclass

# Daniel Solano Gómez <gentoo@sattvik.com>
# @BLURB: Eclass for Clojure projects
# @DESCRIPTION:
# This eclass extends the functionality of Java eclasses to support Clojure
# projects.
#
# @EXAMPLE:
# The following example uses Clojure 1.0.0 and includes a compatible version of
# clojure-contrib.
#
# @CODE
# CLOJURE_VERSION="1.0.0"
# WANT_CONTRIB="yes"
# import java-pkg-2 java-ant-2 clojure
# @CODE
inherit java-pkg-2
local ECLOJURE_CDEPEND=""
local ECLOJURE_DEPEND=""
local ECLOJURE_RDEPEND=""
# @ECLASS-VARIABLE: CLOJURE_VERSION
# @DESCRIPTION:
# Sets the version of Clojure to use. This variable should be set before the
# eclass is imported.
CLOJURE_VERSION=${CLOJURE_VERSION:-1.0}
# @ECLASS-VARIABLE: WANT_CLOJURE_CONTRIB
# @DESCRIPTION:
# If set, this variable will cause the eclass to depend on a suitable version of
# clojure-contrib. By default, this value is unset. This variable should be set
# before the eclass is imported.
WANT_CLOJURE_CONTRIB=${WANT_CLOJURE_CONTRIB:-}
# @ECLASS-VARIABLE: CLOJURE_CONTRIB_VERSION
# @DESCRIPTION:
# Sets the version of Clojure-conrib to use. This variable should be set before
# the eclass is imported. This variable has no effect if WANT_CLOJURE_CONTRIB
# is not set. By default, it will use the latest version compatible with
# CLOJURE_VERSION.
CLOJURE_CONTRIB_VERSION=${CLOJURE_CONTRIB_VERSION:-${CLOJURE_VERSION}}
# @ECLASS-VARIABLE: CLOJURE_BOOTSTRAP_MODE
# @DESCRIPTION:
# If set, the eclass will not pull in any Clojure dependencies or export the
# compile function. This should be used only for the ebuilds that build
# Clojure itself.

# @FUNCTION: clojure_dosrc
# @USAGE: [--nojava] [--zip-name NAME] <DIR> ...
# @DESCRIPTION:
# Installs a zip file containing the source for a package so that it can be used
# in IDEs like Eclipse and NetBeans. It will recursively search for source
# files below each of the given directories and add them to the zip file. Each
# directory DIR is the base directory for a source tree.
#
# By default, the zip file’s name is ‘${PN}-src.zip’. This can be changed by
# using the ‘--zip-name NAME’ argument. The default is also to zip up both Java
# and Clojure source files, i.e. ‘*.clj’ and ‘*.java’ files. The packaging of
# Java source files can be disabled through the use of the ‘--nojava’ argument.
