# @ECLASS: xemacs-elisp-common.eclass
# @MAINTAINER:
# xemacs@gentoo.org
# @BLURB: XEmacs-related installation utilities
# @DESCRIPTION:
#
# Usually you want to use this eclass for (optional) XEmacs support of
# your package. This is NOT for GNU Emacs!
#
# Many of the steps here are sometimes done by the build system of your
# package (especially compilation), so this is mainly for standalone elisp
# files you gathered from somewhere else.
#
# When relying on the xemacs USE flag, you need to add
#
# xemacs? ( virtual/xemacs )
#
# to your DEPEND/RDEPEND line and use the functions provided here to bring
# the files to the correct locations.
#
# .SS
# src_compile() usage:
#
# An elisp file is compiled by the xemacs-elisp-compile() function
# defined here and simply takes the source files as arguments.
#
# xemacs-elisp-compile *.el || die "xemacs-elisp-compile failed"
#
# Function xemacs-elisp-make-autoload-file() can be used to generate a
# file with autoload definitions for the lisp functions. It takes a
# list of directories (default: working directory) as its argument.
# Use of this function requires that the elisp source files contain
# magic ";;;###autoload" comments. See the XEmacs Lisp Reference Manual
# (node "Autoload") for a detailed explanation.
#
# .SS
# src_install() usage:
#
# The resulting compiled files (.elc) should be put in a subdirectory of
# /usr/lib/xemacs/site-lisp/ which is named after the first argument
# of elisp-install(). The following parameters are the files to be put in
# that directory. Usually the subdirectory should be ${PN}, you can choose
# something else, but remember to tell elisp-site-file-install() (see below)
# the change, as it defaults to ${PN}.
#
# elisp-install ${PN} *.el *.elc || die "elisp-install failed"
#
SITEPACKAGE=/usr/lib/xemacs/site-packages
XEMACS=/usr/bin/xemacs
XEMACS_BATCH_CLEAN="${XEMACS} --batch --no-site-file --no-init-file"
# @FUNCTION: xemacs-elisp-compile
# @USAGE: <list of elisp files>
# @DESCRIPTION:
# Byte-compile elisp files with xemacs
xemacs-elisp-compile () {
${XEMACS_BATCH_CLEAN} -f batch-byte-compile "$@"

-l autoload -f batch-update-autoloads "$@"
}
# @FUNCTION: xemacs-elisp-install
# @USAGE: <subdirectory> <list of files>
# @DESCRIPTION:
# Install elisp source and byte-compiled files. All files are installed
# in site-packages in their own directory, indicated by the first
# argument to the function.
xemacs-elisp-install () {
