The majority of elisp packages # will only need to define the standard ebuild variables (like SRC_URI) # and optionally SITEFILE for successful installation. # # Emacs support for other than pure elisp packages is handled by # elisp-common.eclass where you won't have a dependency on Emacs itself. # All elisp-* functions are documented there. # # If the package's source is a single (in whatever way) compressed elisp # file with the file name ${P}.el, then this eclass will move ${P}.el to # ${PN}.el in src_unpack(). # @ECLASS-VARIABLE: NEED_EMACS # @DEFAULT_UNSET # @DESCRIPTION: # If you need anything different from Emacs 21, use the NEED_EMACS # variable before inheriting elisp.eclass. Set it to the major version # your package uses and the dependency will be adjusted. # @ECLASS-VARIABLE: ELISP_PATCHES # @DEFAULT_UNSET # @DESCRIPTION: # Space separated list of patches to apply after unpacking the sources. # Patch files are searched for in the current working dir, WORKDIR, and # FILESDIR. # @ECLASS-VARIABLE: ELISP_REMOVE # @DEFAULT_UNSET # @DESCRIPTION: # Space separated list of files to remove after unpacking the sources. # @ECLASS-VARIABLE: SITEFILE # @DEFAULT_UNSET # @DESCRIPTION: # Name of package's site-init file. The filename must match the shell # pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are # reserved for internal use. "50${PN}-gentoo.el" is a reasonable choice # in most cases. # @ECLASS-VARIABLE: ELISP_TEXINFO # @DEFAULT_UNSET # @DESCRIPTION: # Space separated list of Texinfo sources. Respective GNU Info files # will be generated in src_compile() and installed in src_install(). # @ECLASS-VARIABLE: DOCS # @DEFAULT_UNSET # @DESCRIPTION: # DOCS="blah.txt ChangeLog" is automatically used to install the given # files by dodoc in src_install(). inherit elisp-common eutils case "${EAPI:-0}" in 0|1) EXPORT_FUNCTIONS src_{unpack,compile,install} \ pkg_{setup,postinst,postrm} ;; *) EXPORT_FUNCTIONS src_{unpack,prepare,configure,compile,install} \ pkg_{setup,postinst,postrm} ;; esac DEPEND=">=virtual/emacs-${NEED_EMACS:-21}" RDEPEND="${DEPEND}" # @FUNCTION: elisp_pkg_setup # @DESCRIPTION: # Test if the eselected Emacs version is sufficient to fulfil the major # version requirement of the NEED_EMACS variable. elisp_pkg_setup() { elisp-need-emacs "${NEED_EMACS:-21}" case $? in 0) ;; 1) die "Emacs version too low" ;; *) die "Could not determine Emacs version" ;; esac } # @FUNCTION: elisp_src_unpack # @DESCRIPTION: # Unpack the sources; also handle the case of a single *.el file in # WORKDIR for packages distributed that way.
