I just realized that I have installed IDL (6.4 and 7.0) in a path with
spaces (c:\Program Files\...) now, and my previous installation might
have been in a path without spaces. Is it possible that Emacs/idlwave
choke on that when looking for the IDL assistant?
I didn't use to install command-line stuff and stuff coming from the
Unix world in a path with spaces, because I had a lot of trouble in the
past (MiKTeX, for example). This time it looks like I didn't bother with
IDL, maybe thinking that those petty problems might be overcome in the
21st century.
So before going through the hazzle of reinstalling IDL, I figured I'd
ask if someone can confirm this might be a problem, or how to overcome it.
Again, the two possibly affected entries in my .emacs are
;; The location of the IDL library directories, both standard, and your
own.
;; note that the initial "+" expands the path recursively
(setq idlwave-library-path
'("+C:\Program Files\ITT\IDL64\lib" "+C:\path\to\more\idl_stuff"))
;; location of the IDL system directory (try "print,!DIR")
(setq idlwave-system-directory "C:\Program Files\ITT\IDL64")
Cheers,
Benjamin
