Emacs Fortran90 mode....

Emacs Fortran90 mode....

[Mika Salonoja]

Hi there.

I'm just beginning to use Emacs on Debian Linux for Fortran 90/95 
programming and I have three (hopefully) elemental questions:

1. How do I set Emacs f90 mode so, that all the indents and capitalized 
keywords appear automatically. Now they're available as menu options, but 
cannot be left permanently "on"

2. Where can I find more info about emacs f90 mode? Are there, for example, 
different kinds of .emacs files available which I could try to use?

3. I use emacs with KDE 3.1 and I have a roller mouse. Most Linux editors 
and other GUI-programs scroll up and down with the mouse roller whell, but 
Emacs does not. Why is that?

regards,
Mika

Wow, two Fortran questions in g.e.h in one day!

I don't know what you mean with respect to the indentation appearing
"automatically". Pressing the tab key on a line of code will indent
it. F90 mode has the command `f90-indent-subprogram', on C-M-q, which
will indent the whole of the current subprogram.
`f90-indent-new-line', C-j, will indent the current line and start a
new, indented line.

To have keywords be capitalized automatically in f90-mode, add the
following to your .emacs file:

(setq f90-auto-keyword-case 'capitalize-word)

Or you can use the customize interface (see below) to achieve the
same result.

The commentary section at the start of the file f90.el describes some
of the possibilities. I'm afraid there is no section about F90 mode in
the Emacs manual (I started writing one a while ago but haven't
finished it). You could use M-x customize-group f90 to see what
choices are available.

The luxury of choice (or something...)

There are various ways to enable mouse wheel support. Try:

(require 'mwheel)
(mwheel-install)

in your .emacs.

The official way is (mouse-wheel-mode 1)

Someone ought to change the commentary of mwheel.el then. :)

Here is the 3rd question of the day: 

I am wondering if f90-imenu can be modified so that it also lists all
the (used) functions in the used modules, regardless of whether those
modules are being visited by emacs or not. If one clicks on an item in
the f90-imenu, file containing that subroutine/function must be
visited and the current point must move to the beginning of that
subroutine/function. Wouldn't this be nice?

I don't know how difficult to implement this though (I have little
knowledge in lisp).

Best,

FCC.

I think it's a bit outside of the scope of `imenu' and more
the job of etags.  M-! etags *.f90 RET and then M-. somefun RET
should do what you want, more or less.
