Branch: MAIN
Changes since 1.44: +6 -1 lines
Sync eclasses from Emacs overlay (revision 1506).

elisp.eclass:
Update documentation.

elisp-common.eclass:
The nullglob shell option is not needed in elisp-site-regen, because
inside the loop we test for existence of all files. See also bug 328863.
The temporary file needs only be removed in the no changes case.

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 # @DEFAULT_UNSET
32 # @DESCRIPTION:
33 # If you need anything different from Emacs 21, use the NEED_EMACS
34 # variable before inheriting elisp.eclass. Set it to the major version
35 # your package uses and the dependency will be adjusted.
36
37 # @ECLASS-VARIABLE: ELISP_PATCHES
38 # @DEFAULT_UNSET
39 # @DESCRIPTION:
40 # Any patches to apply after unpacking the sources. Patches are searched
41 # both in ${PWD} and ${FILESDIR}.
42
43 # @ECLASS-VARIABLE: SITEFILE
44 # @DEFAULT_UNSET
45 # @DESCRIPTION:
46 # Name of package's site-init file. The filename must match the shell
47 # pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are
48 # reserved for internal use. "50${PN}-gentoo.el" is a reasonable choice
49 # in most cases.
50
51 # @ECLASS-VARIABLE: ELISP_TEXINFO
52 # @DEFAULT_UNSET
53 # @DESCRIPTION:
54 # Space separated list of Texinfo sources. Respective GNU Info files
55 # will be generated in src_compile() and installed in src_install().
56
57 # @ECLASS-VARIABLE: DOCS
58 # @DEFAULT_UNSET
59 # @DESCRIPTION:
60 # DOCS="blah.txt ChangeLog" is automatically used to install the given
61 # files by dodoc in src_install().
