Re: [Algol68-user] Algol 68 Emacs mode

Hi Jose, 

Sorry to trouble you...

I tried to test drive the emacs .el code, but sadly I am  not regular
emacs user and encountered some problems:

None the less I pirated what I could of php's .el files
so:   /usr/share/emacs/site-lisp/site-start.d/php-mode-init.el (219 bytes)
gave: /usr/share/emacs/site-lisp/site-start.d/algol68-mode-init.el (238 bytes)
------ 8>< - - - - snip-here - - - - - - - - - - - - - - - - - - - -
;; Use algol68-mode for .a68, .8 and .algol68 files

(autoload 'algol68-mode "algol68-mode" "Major mode for editing ALGOL68` code." t)

(add-to-list 'auto-mode-alist
             '("\\.a68\\'\\|\\.8\\'\\|\\.algol68\\'" . algol68-mode))
------ 8>< - - - - snip-here - - - - - - - - - - - - - - - - - - - -

Then I go into emacs and run "M-x byte-compile-file" on both
algol68-mode-init.el AND algol68-mode.el (aka a68-mode.el)

Here is the compile error I got:
------ 8>< - - - - snip-here - - - - - - - - - - - - - - - - - - - -
-uu-:---F1  algol68-mode.el      (Emacs-Lisp)--L1--Top-------------------------------

  ** The function `syntax-ppss' is not known to be defined.
------ 8>< - - - - snip-here - - - - - - - - - - - - - - - - - - - -

But I end up with:
-rw-r--r-- 1 root root  7724 Mar  6 11:35 /usr/share/emacs/site-lisp/algol68-mode.el
-rw-r--r-- 1 root root  4469 Mar  6 11:36 /usr/share/emacs/site-lisp/algol68-mode.elc
-rw-r--r-- 1 root root 13267 May 25  2008 /usr/share/emacs/site-lisp/php-mode.elc
-rw-r--r-- 1 root root   231 Mar  6 11:37 /usr/share/emacs/site-lisp/site-start.d/algol68-mode-init.el
-rw-r--r-- 1 root root   819 Mar  6 11:38 /usr/share/emacs/site-lisp/site-start.d/algol68-mode-init.elc
-rw-r--r-- 1 root root   219 May 25  2008 /usr/share/emacs/site-lisp/site-start.d/php-mode-init.el

OK... so now I try it:
------ 8>< - - - - snip-here - - - - - - - - - - - - - - - - - - - -
$ emacs --no-windows hw.a68
File Edit Options Buffers Tools Help                                                                                                        
BEGIN
  printf($"Hello, world!"l$)
END
-uu-:---F1  hw.a68            (Fundamental)--L1--All-----------------------

------ 8>< - - - - snip-here - - - - - - - - - - - - - - - - - - - -

Can you give this poor emacs/el illiterate soul some hints?

Cheers
Neville
