Hello All,
I tried the structure completion in IdlWAVE by adding

(add-hook 'idlwave-load-hook
(lambda () (require 'idlw-complete-structtag)))

in my .emacs file and then proceeded to add the
idlw-complete-structtag.el file to /usr/local/share/emacs/site-lisp/
where the rest of the idl*.el files are. Yet when I load up Emacs
I get the following error:
File mode specification error: (file-error "Cannot open load file"
"idlw-complete-structtag")

OS: Linux Redhat 8.0
Emacs Version: GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll
bars) of 2002-08-28 on astest
IDL Version : 5.5

Any suggestions? Thanks,
Karthik.

No worries... it came up off-list. I've added it to the FAQ (to be
available with the upcoming IDLWAVE release... any... day.... now).

Hi JD,

Thanks. I seem to have missed the earlier topic thread on this.

Cheers,

Sigh... tags-tables are silly little scans of relevant locations in a
file, and are useless for IDLWAVE. What this means that ESC-Tab doesn't
receive the `idlwave-complete' binding it should, but instead has the old
`complete-symbol'. Any reason you're not using M-Tab? I recall someone
reporting a few issues binding M-Tab under MacOSX.

Well, the .plist file is not a regular file like .cshrc, but needs to be
created in an XML type language. This describes how:

http://developer.apple.com/qa/qa2001/qa1067.html

Can you give that a try and let us know how it goes? You could also
define an IDL_PATH in your .emacs, something like

(setenv "IDL_PATH" "<IDL_DEFAULT>:/path/to/something:+/otherpath/to/something/else ")

Any luck with that?

Thanks for the XML-hint, I embarrassingly was totally oblivious to that
and treated it as a shell script (a la .cshrc).

So I used 'Property List Editor' but all the combinations I could think
of did not change anything. Emacs.app would never see my 'IDL_PATH'. I
tried with and without quotation marks, with '+' signs or avoiding them,
with '<IDL_DEFAULT>' or without, etc. the IDL shell in Emacs.app would
always only see the default path. I might do some other stupid mistake?

Your other hint (setenv in .emacs) works excellently though, so I am
sticking to that.

Thanks a lot for the help!

Chris
