Cheers all!
I use idl 6.0 on my suse linux. I have been updating my linux and got
the adobe 7.0 that is not working anymore with the -supernasty!- idl
online help (I know the topic has been already faced time ago)
So I was thinking this as a good excuse to migrate to some sort of more
clever way of using the online help, idlwave or whatever would be good.
I'm using emacs and I'm quite sure it already has idlwave features in
it (ex: I call idl from it by typing ctrl-C-S) but I'm anable to see
the online help provided with idlwave. What should I do? I have tried
to Alt-X-idlwave- but then I don't have any help (only
idlwave-hard-tab) as I would expect. What do I have to do in order to
see it (if this is the right way of doing... ?!?)
I have also downloaded the html online-help (from idlwave.org) and add
the following lines in .emacs
(setq idlwave-html-help-location
"/home/myusername/IDLWAVE/idl_html_help/")
(setq idlwave-help-browser-function 'firefox-browse-url)
but is seems not to work...
Any suggestion and/or help?
Switching to another topic, I come across to this higly interesting
message :
"just find the file idl.chm in a Windows distribution and copy
that file to some convenient location on your Linux box. Install xCHM,
if you don't have it already, and viola! you're reading a Windows Help
file on Linux."
I have downloaded and installed idl6.2 for windows and searched for
idl.chm, but unable to find it anymore!!! Is this another nice joke
from IDL people? Or what? Should I rather use another file and if so,
which one?
Thanks in advance everyone!
S.

menu IDLWAVE->Documentation->Info
then visit topic "The IDLWAVE Major Mode"->Online Help. This will
tell you what you need to know. Briefly, IDLWAVE gives context based
help. Just hit M-? with the cursor in a variety of places
(functions/keywords/system variables/etc.) and you'll be queued up
instantly. Also available from context help or completion (just right
click anything blue).
I should probably remove the "Launch IDL Help" menu item, or change it
to launch the home page of the IDL HTML help. It was created when
IDL's help system was a papyrus parchment roll with charcoal drawings.

I'm not sure where you are getting these function names, but they're
not correct. If you set it up with customize to work, and say "save
for future sessions" this should be a non-issue. Just remove the
help-browser-function line from your .emacs, and IDLWAVE will default
to the system-wide browser. You only really need this variable if you
want different browsers in IDLWAVE vs. other Emacs stuff.

You should make sure your emacs is connected to your desired browser first.
If you want to use w3m (which I prefer since you never leave emacs), make
sure it's configured correctly.
Try the command: M-x browse-url <enter: http://google.com> and see
what happends first.
Do you get the google homepage? Inside an emacs window, or in a separate
browser?
If you don't get either, you've not configured emacs correctly. This needs
to be done before you can get the idlwave help system as it uses URLs for
its help pages.
Hope this helps.
Matt
Check the emacs manual.
AC.28.1 Following URLs
M-x browse-url RET url RET
Load a URL into a Web browser.
The Browse-URL package provides facilities for following URLs specifying
links on the World Wide Web. Usually this works by invoking a web browser,
but you can, for instance, arrange to invoke compose-mail from `mailto:'
URLs.
The general way to use this feature is to type M-x browse-url, which displays
a specified URL. If point is located near a plausible URL, that URL is used
as the default. Other commands are available which you might like to bind to
keys, such as browse-url-at-point and browse-url-at-mouse.
You can customize Browse-URL's behavior via various options in the browse-url
Customize group, particularly browse-url-browser-function. You can invoke
actions dependent on the type of URL by defining browse-url-browser-function
as an association list. The package's commentary available via C-h p provides
more information. Packages with facilities for following URLs should always
go through Browse-URL, so that the customization options for Browse-URL will
affect all browsing in Emacs.

Having trouble following you here. Try this. Open a file named foo.pro.
In it, type:
a=convol(
and with the cursor after the "(", hit M-?. You should have a browser
popup to the CONVOL page, or a message about problems Emacs is having
opening a browser. Have you actually installed w3m? It doesn't come with
Emacs by default (and requires an external command-line tool). You
can configure your default browser like M-x customize [RET]
browse-url-browser-function [RET] and try the various methods until you
find one which works. Then just "save for future sessions" and you should
be good to go.

I'm not actually quite sure I'm doing things properly :((
I have completion only if I open IDL in my emacs,i.e. I have to hit C-c
C-s and then for a given command in the IDL command line I get a
completion or a list of possible completion. But not in the emacs file
right away. Also, nothing happens when I hit M-? or C-c ? (is
posssible because in my keybord ? is called with shift-+
combination???)
In any case, if from the idl command line (open by C-c C-s I right
click on one of the possible combination, nothing happens but I get the
following message Wrong type argument: listp, firefox-browse-url).
However, if in .emacs I set the following way
(setq idlwave-help-browser-function 'w3m-browse-url)
a new emacs window pop-up, with the title *IDLWAVE Help*, but nothing
is displayed and the message Wrong type argument: listp, w3m-browse-url
still appear.
I feel really like a stupid but I fear I'm missing something very
basic, indeed.... :(
Here is my .emacs as it looks right now
(setq load-path (cons "/usr/local/share/emacs/site-lisp" load-path))
(setq idlwave-help-directory "/usr/local/etc")
(autoload 'idlwave-mode "idlwave" "IDLWAVE Mode" t)
(autoload 'idlwave-shell "idlw-shell" "IDLWAVE Shell" t)
(setq auto-mode-alist
(cons '("\\.pro\\'" . idlwave-mode) auto-mode-alist))
(setq idlwave-help-browser-function 'w3m-browse-url)

OK, I have finally decided to bite the bullet and get idlwave running. The
first problem is that I have used 'vi' all my computing life, and I'm having
a hard time remembering all the commands for emacs. The second problem is
that on my Mac, when I fire up emacs in an xterm, it does not have any
widgets that I can use to learn the system, so I have decided to install
Xemacs instead (version 21.4.9). I figured I could learn emacs this way, and
then go back to plain emacs if necessary, once I learned the ropes.
So far so good. I have confirmed (I think) that the IDLWAVE package has been
installed. However, when I try to load the tutorial.pro routine to see the
magic that IDLWAVE can do, I get an error message:
File mode specification error: (void-variable browse-url-browser-function)
And the there is no hint that it has heard of IDLWAVE mode.
Here is my
~/.xemacs/init.el
127 rfrench@telesto> cat init.el
(setq load-path (cons "/usr/local/share/emacs/site-lisp" load-path))
(autoload 'idlwave-mode "idlwave" "IDLWAVE Mode" t)
(autoload 'idlwave-shell "idlw-shell" "IDLWAVE Shell" t)
(setq auto-mode-alist
(cons '("\\.pro\\'" . idlwave-mode) auto-mode-alist))
I'd be very grateful if someone could tell me how to get xemacs to recognize
that this file is an IDL program and get into the proper mode for it.
Many thanks!
