The Emacs major mode for IDL programming has received a few minor bug
fixes by J.D. Smith. The fixes refer to some problems with the fontifying
(= syntax coloring) of objects in IDL source code.
I am about ready to publish idl.el version 1.41, but it still has one
basic flaw that should be fixed first. Anyone with a little experience
with Emacs lisp is asked to help out. (I tried posting in comp.emacs
already, but only received a reference to another large package.)
The following construct for font-locking is in idl.el (lines 478-532)
(defvar idl-font-lock-keywords
(if (or (save-match-data (string-match "Lucid" emacs-version))
(not (boundp 'emacs-minor-version)) (< emacs-minor-version 30))
;;
;; For Emacs 19.29 and below, and Lucid/XEmacs.
(
;;; some font-locking code
)
;; For Emacs 19.30 and up
(
;;; other font-locking code
)
"Default expressions to highlight in IDL mode.")
The problems began with Emacs 20, since only the minor-version is checked.
There is also a variable emacs-major-verion which should be checked
and equal to 19 for the if clause. The correct way of checking the
version number should also take into account that the variables were
undefined in Emacs versions 19.23 and before (-> use boundp to check
if variable exists).
Something else is very strange: In the Emacs 19.30+ part, the function
font-lock-match-c++-style-declaration-item-and-skip-to-next is used.
This function is only defined Xemacs versions of font-lock, but not
in the GNU Emacs version. Does anyone know if it should stay in there?
Thanks for the help,
Kevin
