9# installation utilities. 11# utilities.
12#
13# USAGE:
14#
15# Usually you want to use this eclass for (optional) GNU Emacs support of
16# your package. This is NOT for XEmacs!
17# Many of the steps here are sometimes done by the build system of your
18# package (especially compilation), so this is mainly for standalone elisp
19# files you gathered from somewhere else.
20# When relying on the emacs USE flag, you need to add
21#
22# emacs? ( virtual/emacs )
23#
24# to your DEPEND/RDEPEND line and use the functions provided here to bring
25# the files to the correct locations.
26#
27# src_compile() usage:
28# --------------------
29#
30# An elisp file is compiled by the elisp-compile() function defined here and
31# simply takes the source files as arguments. In the case of interdependent
32# elisp files, you can use the elisp-comp() function which makes sure all
33# files are loadable.
34#
35# elisp-compile *.el || die "elisp-compile failed!"
36# or
37# elisp-comp *.el || die "elisp-comp failed!"
38#
39# Function elisp-make-autoload-file() can be used to generate a file with
40# autoload definitions for the lisp functions. It takes the output file name
41# (default: "${PN}-autoloads.el") and a list of directories (default: working
42# directory) as its arguments. Use of this function requires that the elisp
43# source files contain magic ";;;###autoload" comments. See the Emacs Lisp
44# Reference Manual (node "Autoload") for a detailed explanation.
45#
46# src_install() usage:
47# --------------------
48#
49# The resulting compiled files (.elc) should be put in a subdirectory of
50# /usr/share/emacs/site-lisp/ which is named after the first argument
51# of elisp-install(). The following parameters are the files to be put in
52# that directory. Usually the subdirectory should be ${PN}, you can choose
53# something else, but remember to tell elisp-site-file-install() (see below)
54# the change, as it defaults to ${PN}.
55#
56# elisp-install ${PN} *.elc *.el || die "elisp-install failed!"
57#
58# To let the Emacs support be activated by Emacs on startup, you need
59# to provide a site file (shipped in ${FILESDIR}) which contains the startup
60# code (have a look in the documentation of your software). Normally this
61# would look like this:
62#
63# ;;; csv-mode site-lisp configuration
64#
65# (add-to-list 'load-path "@SITELISP@")
66# (add-to-list 'auto-mode-alist '("\\.csv\\'" . csv-mode))
67# (autoload 'csv-mode "csv-mode" "Major mode for editing csv files." t)
68#
69# If your Emacs support files are installed in a subdirectory of
70# /usr/share/emacs/site-lisp/ (which is recommended if more than one file is
71# installed), you need to extend Emacs' load-path as shown in the first
72# non-comment. The elisp-site-file-install() function of this eclass will
73# replace "@SITELISP@" by the actual path.
74# The next line tells Emacs to load the mode opening a file ending with
75# ".csv" and load functions depending on the context and needed features.
76# Be careful though. Commands as "load-library" or "require" bloat the
77# editor as they are loaded on every startup. When having a lot of Emacs
78# support files, users may be annoyed by the start-up time. Also avoid
79# keybindings as they might interfere with the user's settings. Give a hint
80# in pkg_postinst(), which should be enough.
81# The naming scheme for this site file is "[0-9][0-9]*-gentoo.el", where the
82# two digits at the beginning define the loading order. So if you depend on
83# another Emacs package, your site file's number must be higher!
84# Best practice is to define a SITEFILE variable in the global scope of your
85# ebuild (right after DEPEND e.g.):
86#
87# SITEFILE=50${PN}-gentoo.el
88#
89# Which is then installed by
90#
91# elisp-site-file-install "${FILESDIR}/${SITEFILE}"
92#
93# in src_install(). If your subdirectory is not named ${PN}, give the
94# differing name as second argument.
95#
96# pkg_postinst() / pkg_postrm() usage:
97# ------------------------------------
98#
99# After that you need to recreate the start-up file of Emacs after emerging
100# and unmerging by using
101#
102# pkg_postinst() {
103# elisp-site-regen
104# }
105#
106# pkg_postrm() {
107# elisp-site-regen
108# }
109#
110# When having optional Emacs support, you should prepend "use emacs &&" to
111# above calls of elisp-site-regen(). Don't use "has_version virtual/emacs"!
112# When unmerging the state of the USE flag emacs is taken from the package
113# database and not from the environment, so it is no problem when you unset
114# USE=emacs between merge und unmerge of a package.
115#
116# Miscellaneous functions:
117# ------------------------
118#
119# elisp-emacs-version() outputs the version of the currently active Emacs.
120#
121# As always: Feel free to contact Emacs team through emacs@gentoo.org if you
122# have problems, suggestions or questions.
