|
|
# Usually you want to use this eclass for (optional) XEmacs support of |
| 21 |
|
|
# your package. This is NOT for GNU Emacs! |
| 22 |
|
|
# |
| 23 |
|
|
# Many of the steps here are sometimes done by the build system of your |
| 24 |
|
|
# package (especially compilation), so this is mainly for standalone elisp |
| 25 |
|
|
# files you gathered from somewhere else. |
| 26 |
|
|
# |
| 27 |
|
|
# When relying on the xemacs USE flag, you need to add |

# Function xemacs-elisp-make-autoload-file() can be used to generate a |

# file with autoload definitions for the lisp functions. It takes a |
| 50 |
|
|
# list of directories (default: working directory) as its argument. |
| 51 |
|
|
# Use of this function requires that the elisp source files contain |
| 52 |
|
|
# magic ";;;###autoload" comments. See the XEmacs Lisp Reference Manual |
| 53 |
|
|
# (node "Autoload") for a detailed explanation. |

# The resulting compiled files (.elc) should be put in a subdirectory |
| 59 |
|
|
# of /usr/lib/xemacs/site-lisp/ which is named after the first |
| 60 |
|
|
# argument of xemacs-elisp-install(). The following parameters are |
| 61 |
|
|
# the files to be put in that directory. Usually the subdirectory |
| 62 |
|
|
# should be ${PN}, but you can choose something else. |

| 66 |
graaff |
1.4 |
# To let the XEmacs support be activated by XEmacs on startup, you need |
| 67 |
|
|
# to provide a site file (shipped in ${FILESDIR}) which contains the |
| 68 |
|
|
# startup code (have a look in the documentation of your software). |
| 69 |
|
|
# Normally this would look like this: |
| 70 |
|
|
# |
| 71 |
|
|
# (add-to-list 'load-path "@SITELISP@") |
| 72 |
|
|
# (add-to-list 'auto-mode-alist '("\\.csv\\'" . csv-mode)) |
| 73 |
|
|
# (autoload 'csv-mode "csv-mode" "Major mode for csv files." t) |
| 74 |
|
|
# |
| 75 |
|
|
# If your XEmacs support files are installed in a subdirectory of |
| 76 |
|
|
# /usr/share/xemacs/site-packages/ (which is strongly recommended), you need |
| 77 |
|
|
# to extend XEmacs' load-path as shown in the first non-comment line. |
| 78 |
|
|
# The xemacs-elisp-site-file-install() function of this eclass will replace |
| 79 |
|
|
# "@SITELISP@" by the actual path. |
| 80 |
|
|
# |
| 81 |
|
|
# The next line tells XEmacs to load the mode opening a file ending |
| 82 |
|
|
# with ".csv" and load functions depending on the context and needed |
| 83 |
|
|
# features. Be careful though. Commands as "load-library" or "require" |
| 84 |
|
|
# bloat the editor as they are loaded on every startup. When having |
| 85 |
|
|
# many XEmacs support files, users may be annoyed by the start-up time. |
| 86 |
|
|
# Also avoid keybindings as they might interfere with the user's |
| 87 |
|
|
# settings. Give a hint in pkg_postinst(), which should be enough. |
| 88 |
|
|
# |
| 89 |
|
|
# The naming scheme for this site-init file matches the shell pattern |
| 90 |
|
|
# "[1-8][0-9]*-gentoo*.el", where the two digits at the beginning define |
| 91 |
|
|
# the loading order (numbers below 10 or above 89 are reserved for |
| 92 |
|
|
# internal use). So if your initialisation depends on another XEmacs |
| 93 |
|
|
# package, your site file's number must be higher! If there are no such |
| 94 |
|
|
# interdependencies then the number should be 50. Otherwise, numbers |
| 95 |
|
|
# divisible by 10 are preferred. |
| 96 |
|
|
# |
| 97 |
|
|
# Best practice is to define a SITEFILE variable in the global scope of |
| 98 |
|
|
# your ebuild (e.g., right after S or RDEPEND): |
| 99 |
|
|
# |
| 100 |
|
|
# SITEFILE="50${PN}-gentoo.el" |
| 101 |
|
|
# |
| 102 |
|
|
# Which is then installed by |
| 103 |
|
|
# |
| 104 |
|
|
# xemacs-elisp-site-file-install "${FILESDIR}/${SITEFILE}" || die |
| 105 |
|
|
# |
| 106 |
|
|
# in src_install(). Any characters after the "-gentoo" part and before |
| 107 |
|
|
# the extension will be stripped from the destination file's name. |
| 108 |
|
|
# For example, a file "50${PN}-gentoo-${PV}.el" will be installed as |
| 109 |
|
|
# "50${PN}-gentoo.el". If your subdirectory is not named ${PN}, give |
| 110 |
|
|
# the differing name as second argument. |
