13 # @BLURB: Eclass for Emacs Lisp packages
16 # This eclass is designed to install elisp files of Emacs related
17 # packages into the site-lisp directory. The majority of elisp packages
18 # will only need to define the standard ebuild variables (like SRC_URI)
19 # and optionally SITEFILE for successful installation.
21 # Emacs support for other than pure elisp packages is handled by
22 # elisp-common.eclass where you won't have a dependency on Emacs itself.
23 # All elisp-* functions are documented there.
25 # If the package's source is a single (in whatever way) compressed elisp
26 # file with the file name ${P}.el, then this eclass will move ${P}.el to
27 # ${PN}.el in src_unpack().
29 # @ECLASS-VARIABLE: NEED_EMACS
32 # If you need anything different from Emacs 23, use the NEED_EMACS
33 # variable before inheriting elisp.eclass. Set it to the version your
34 # package uses and the dependency will be adjusted.
36 # @ECLASS-VARIABLE: ELISP_PATCHES
39 # Space separated list of patches to apply after unpacking the sources.
40 # Patch files are searched for in the current working dir, WORKDIR, and
41 # FILESDIR. This variable is semi-deprecated, preferably use the
42 # PATCHES array instead if the EAPI supports it.
44 # @ECLASS-VARIABLE: ELISP_REMOVE
47 # Space separated list of files to remove after unpacking the sources.
49 # @ECLASS-VARIABLE: SITEFILE
52 # Name of package's site-init file. The filename must match the shell
53 # pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are
54 # reserved for internal use. "50${PN}-gentoo.el" is a reasonable choice
57 # @ECLASS-VARIABLE: ELISP_TEXINFO
60 # Space separated list of Texinfo sources. Respective GNU Info files
61 # will be generated in src_compile() and installed in src_install().
