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().
29
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.
35
36 # @ECLASS-VARIABLE: ELISP_PATCHES
37 # @DESCRIPTION:
38 # Any patches to apply after unpacking the sources. Patches are searched
39 # both in ${PWD} and ${FILESDIR}.
40
41 # @ECLASS-VARIABLE: SITEFILE
42 # @DESCRIPTION:
43 # Name of package's site-init file. The filename must match the shell
44 # pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are
45 # reserved for internal use. "50${PN}-gentoo.el" is a reasonable choice
46 # in most cases.
47
48 # @ECLASS-VARIABLE: ELISP_TEXINFO
49 # @DESCRIPTION:
50 # Space separated list of Texinfo sources. Respective GNU Info files
51 # will be generated in src_compile() and installed in src_install().
52
53 # @ECLASS-VARIABLE: DOCS
54 # @DESCRIPTION:
55 # DOCS="blah.txt ChangeLog" is automatically used to install the given
56 # files by dodoc in src_install().
