modes not doing much

[YAD]

So far I've used Ruby mode and HTML mode.
No colors, no auto-indent on <rtrn>.

So what are the modes doing?  Vim and even the
Firefox source viewer have syntax-based colors.
Isn't Emacs supposed to do that too?

Also, Lisp .cl files and Python .py files are coming up in
Fundamental mode, while OCaml .ml files come up in Lisp mode.
What the heck is going on? :(

Try
M-x font-lock-mode
for colouring

to make this permanent, place this in your .emacs file

(add-hook 'html-mode-hook '(lambda ()
                                  (turn-on-font-lock))

(add-hook 'haskell-mode-hook '(lambda ()
                                  (turn-on-font-lock))


I have auto-indent enabled for C, but I can't see where
it is switched on.



To associate a file name with a mode, use
(add-to-list 'auto-mode-alist '("\\.cl\\'" . lisp-mode) 't)
(add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode) 't)
I can't find the mode for Ocaml - you might need to google for one.


Python should be bound by default - what does
C-h v auto-mode-alist RET
report?



These code snippets are for XEmacs - they should
work on GNU Emacs, but I can't guarantee that.

YAD,

Looking a bit closer at my auto-mode-alist shows
it contains, amongs other entries,

("\\.py$" . python-mode)
("\\.ml[iylp]?$" . caml-mode)
("\\.ml\\'" . lisp-mode)

The second entry means .ml optionally follwed by i, y, l, or p,
are in caml-mode.

However, the last entry overrides .ml,
so adding to your .emacs
(remove-alist 'auto-mode-alist '"\\.ml\\'")
should work, if emacs's auto-mode-alist is the same as
XEmacs's.

I have

(global-font-lock-mode 1)

in my .emacs. Using emacs-snaphot

,----
| GNU Emacs 22.0.50.1 (i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of
| 2006-01-16 on vernadsky, modified by Debian
`----

I have to refresh the screen (hilite & unhilite) the text for c mode
hiliting to start working. Why is this?

In addition to what others have said :

* Common Lisp files normally end in .lsp or .lisp this is what Emacs
expects

* You're probably using an old Emacs with no Python support.  This will
be fixed in the v22.  Until then you can install python mode from the
python distribution.

* Indentation in Emacs is via tab, hit tab and it will auto indent the
current like to whatever the mode considers the right indentation.  You
can get the same behaviour by ending lines with M-j.  It doesn't do it
automatically so the user has the choice to ignore what the mode thinks
is right easily.

Does it have to be switched on? If a mode does neither
coloring nor indentation, then what does it do?

I don't have python-mode or caml-mode, but I'm using GNU.
Video games and the "Emacs Psychiatrist", but RMS/GNU couldn't fit
in important language editing modes, or make sure the modes work.

lisp-mode colors are working now that I moved my .cl file to .l
No indentation anywhere though.

Thanks for the help.

I just downloaded 21.4a a couple weeks ago.

I just figured that out.  It's been over a decade since I used Emacs 
regularly, so my recollection of it is fragmented.  Effusive and abject 
apologies to Mr. Stallman and all the good people at GNU.

So now you have three things to turn to, when frustrated with Emacs:

* video games
* M-x doctor
* help-gnu-emacs

Here are two more:

* M-x dissociated-press

Others have already helped with the coloring problem, but you may want
to try this in your .emacs to set up auto-indenting for programming
modes you are using:

(add-hook 'perl-mode-hook
          #'(lambda ()
              ;; A better newline
              (local-set-key "\C-m"
#'reindent-then-newline-and-indent)))

This particular example is for perl, adjust the hook name to the name
of your mode hook. For other similar functions to bind to the return
key, try M-x apropos newline-and-indent.

In recent Emacs versions, you can also write this as:

    (add-hook 'perl-mode-hook
              (lambda ()
                ;; A better newline
                (local-set-key (kbd "RET") 'reindent-then-newline-and-indent)))

which I sometimes find cleaner than "\C-\M-\S-foo" stuff :)
