compile-related functions added, for use in Unicode-internal ws -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-01-17 Ben Wing <ben@xemacs.org> * bytecomp-runtime.el: * bytecomp-runtime.el (error-unless-tests-match): New. * bytecomp-runtime.el (byte-compile-file-being-compiled): New. * bytecomp-runtime.el (compiled-if): New. * bytecomp-runtime.el (compiled-when): New. Add functions for dealing with conditional compilation of different code depending on the presence or absence of features. Necessary for some Mule code where code is run during compilation (macros or eval-when-compile) but, depending on how the code is written, the code itself will crash either with or without Unicode-internal. compiled-if and compiled-when are the basic functions for conditional compilation. They automatically trigger an error message upon file loading if, at that time, the test expression that selected which code to compile does not have the same value as at compile time.

;;; site-load.el --- Template file for site-wide XEmacs customization
;; Copyright (C) 1997 Free Software Foundation, Inc.

;; Author: Steven L. Baur <steve@xemacs.org>
;; Keywords: internal

;; This file is part of XEmacs.

;;; Commentary:

;; This is a prototype site-load.el file.
;; The site-load.el mechanism is provided so XEmacs installers can easily
;; dump lisp packages with XEmacs that do not get dumped standardly.

;; The file `site-packages' if it exists should look something like:
;; (setq site-load-packages '(
;; "../lisp/modes/cc-mode.elc"
;; "../lisp/utils/redo.elc"
;; "../lisp/packages/scroll-in-place.elc"
;; )
;; )

;; The first line and the last line must be exact.  Each of the packages
;; listed must be double quoted, have either an absolute path, or a relative
;; to the build src directory path *and* be bytecompiled prior to the attempt
;; to dump.  They also must explicitly have the .elc extension.

;; Because this is a trial implementation and the file is shared with
;; make-docfiles, syntax is strict and unforgiving.  So sue me.  It
;; is still better than the way it used to be.

;; Also note that site-packages belongs in the top level directory not the
;; lisp directory for use with --srcdir configurations.

;;; Code:
(defvar site-load-package-file "../site-packages"
  "File name containing the list of extra packages to dump with XEmacs.")
(defvar site-load-packages nil
  "A list of .elc files that should be dumped with XEmacs.
This variable should be set by `site-load-package-file'.")

;; Load site specific packages for dumping with the XEmacs binary.
(when (file-exists-p site-load-package-file) 
  (let ((file))
    (load site-load-package-file t t t)
    ;; The `pureload' macro is provided as a clue that a package is
    ;; being loaded in preparation of being dumped into XEmacs.
    (defmacro pureload (file)
      (list 'prog1 (list 'load file) '(garbage-collect)))
    (message "Loading site-wide packages for dumping...")
    (while site-load-packages
      (setq file (car site-load-packages))
      (pureload file)
      (setq site-load-packages (cdr site-load-packages)))
    (message "Loading site-wide packages for dumping...done")
    (fmakunbound 'pureload)))

;; This file is intended for end user additions.
;; Put other initialization here, like setting of language-environment, etc.
;; Perhaps this should really be in the site-init.el.

;;; site-load.el ends here
