7# This eclass sets the site-lisp directory for emacs-related packages. 10# @ECLASS: elisp.eclass
11# @MAINTAINER:
12# Feel free to contact the Emacs team through <emacs@gentoo.org> if you
13# have problems, suggestions or questions.
14# @BLURB: Eclass for Emacs Lisp packages
15# @DESCRIPTION:
16#
17# This eclass is designed to install elisp files of Emacs related
18# packages into the site-lisp directory. The majority of elisp packages
19# will only need to define the standard ebuild variables (like SRC_URI)
20# and optionally SITEFILE for successful installation.
21#
22# Emacs support for other than pure elisp packages is handled by
23# elisp-common.eclass where you won't have a dependency on Emacs itself.
24# All elisp-* functions are documented there.
25#
26# If the package's source is a single (in whatever way) compressed elisp
27# file with the file name ${P}.el, then this eclass will move ${P}.el to
28# ${PN}.el in src_unpack().
8 29
9inherit elisp-common 30# @ECLASS-VARIABLE: NEED_EMACS
31# @DESCRIPTION:
32# If you need anything different from Emacs 21, use the NEED_EMACS
33# variable before inheriting elisp.eclass. Set it to the major version
34# your package uses and the dependency will be adjusted.
10 35
11ECLASS=elisp 36# @ECLASS-VARIABLE: DOCS
12INHERITED="$INHERITED $ECLASS" 37# @DESCRIPTION:
38# DOCS="blah.txt ChangeLog" is automatically used to install the given
39# files by dodoc in src_install().
13 40
14source /usr/portage/eclass/elisp-common.eclass 41# @ECLASS-VARIABLE: ELISP_PATCHES
42# @DESCRIPTION:
43# Any patches to apply after unpacking the sources. Patches are searched
44# both in ${PWD} and ${FILESDIR}.
15 45
16# SRC_URI should be set to wherever the primary app-emacs/ maintainer 46# @ECLASS-VARIABLE: SITEFILE
17# keeps the local elisp mirror, since most app-emacs packages are 47# @DESCRIPTION:
18# upstream as a single .el file. 48# Name of package's site-init file. The filename must match the shell
49# pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are
50# reserved for internal use. "50${PN}-gentoo.el" is a reasonable choice
51# in most cases.
