Highlighting of
keywords, comments, strings etc. can be accomplished with
font-lock. If you are using
global-font-lock-mode (in Emacs), or have
font-lock turned on in any other buffer in XEmacs,
it should also automatically work in IDLWAVE buffers. If you'd
prefer invoking font-lock individually by mode, you can enforce
it in idlwave-mode with the following line in your
.emacs:
(add-hook 'idlwave-mode-hook 'turn-on-font-lock)
IDLWAVE supports 3 increasing levels of
syntax highlighting. The variable
font-lock-maximum-decoration determines which level
is selected. Individual categories of special tokens can be
selected for highlighting using the variable
idlwave-default-font-lock-items.
