Need "xemacs/init.el" => "emacs/init.el" help

[Tom Browder]

I have bitten the bullet to start using Emacs vs. my 20+ years using
XEmacs use.  I have never been a real power user, but I have my
init.el doing the things I need most.

So far I have discovered the excellent "M-x list-packages" way to
install packages and have started trying to duplicate the behavior I'm
used to with XEmacs.  I've also discovered Eric Schulte's "Emacs 24
Starter Kit" here:

  http://github.com/eschulte/emacs24-starter-kit/

but I will save that for a bit later.

One of the things I use all the time in XEmacs is NO line wrapping
except when I manually use function "fill-paragraph".  (I have that
bound to a key for ease of use.)  I will admit that the
"fill-paragraph" didn't work reliably in XEmacs in all modes (I hope
Emacs will be able to fix that), but for the most part it does what I
need in XEmacs.  But I cannot get it to work in Emacs.

Here's my entire Emacs init.el at the moment (all blank lines and some
comments removed):

; Personal emacs mods of Tom Browder
(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))
; packages installed via M-x list-packages:
;   perl6-mode
(setq-default major-mode 'text-mode)
(set-default 'truncate-lines t)
(setq-default fill-column 70)
(global-set-key [f6] 'fill-paragraph)
; prefer cperl for Perl 5
(defalias 'perl-mode 'cperl-mode)

So far, and only using a text buffer, the truncate lines t seems to
work, but I can't get any such line to wrap with the "fill-paragraph"
function.

I have read about the init.el entries not normally affecting modes
already loaded without special lisp code.  Is that what may be
happening in my case?

Any help will be greatly appreciated.

BTW, the major motivation for the change to Emacs has been the arrival
of Perl 6 and a special Perl 6 mode available with Emacs.  In
addition, all the *emacs people I correspond with on various projects
use Emacs.  Emacs is still not as pretty in appearance as XEmacs, but
functionality seems much better.

Best regards,

-Tom

Here are some lines from my init file:

;;; Set the major mode for new buffers to text-mode:
(setq major-more 'text-mode)
;;; Set the fill column:
(add-hook 'text-mode-hook (lambda () (setq-default fill-column 66)))

Also, Emacs defines M-q to run fill-paragraph by default; there's
no need to define your own keybinding.


Anyway, I hope this helps.

Hm - `setq-default' in a mode-specific hook?
Isn't that a contradiction in, uhm, purpose?

What happens if you just put

    (setq-default fill-column 66)

in the init file?

Well, there can be such a need even in the face of
default bindings but in this case there isn't as M-q
is very good and especially compared to F6 which is
very bad.

That didn't work, which is why I used the hook.  I forget where I
found that method.  It might even have been in the Emacs manual.
Or it was on someone's web page.  I don't know, it's been years
since I wrote that part.  You're probably right about the
"setq-default", though.  I'll have to try plain "setq" and see
what happens.

There we are in agreement.  I know Emacs defines some function
keys by default, but I generally don't use them.  I have two
function keys set: [f1] for help, and [f12] to compile-command.
Actually, I have [f12] to run the command, S-[f12] to set the
command, and C-[f12] to abort the run.  Since neither the help
function nor compile-command are things I use that much, I'm fine
with them bound to function keys.

Thanks so much, Dale and Emanuel, for the speedy response.  Let me
absorb your inputs...

BTW, the reason I use F6 is, as far as I know, the old XEmacs didn't
use 'M-q' for 'fill-paragraph' or, more likely, I was in a giant rush
years ago to get what I needed going.  As far as F6 being a "bad" key
because it is so far to reach, I'm NOT a touch typist and reaching for
the F6 key decades ago didn't seem like a big deal to me.  The VT
effect, though, is a big deal and I think I can get my old brain
around using 'M-q'.

I'll report back results when I get a chance to do some tests..

Cheers!

Okay, all is well with fill-paragraph--I stupidly was using a long line
with NO spaces to test!

Thanks for your help!

Best,

Perhaps some other configuration is interfering.

Try this single line in a file ~/fill-column.el:

    (setq-default fill-column 15)

(It is set to a ridiculous low just to see if
it works.)

Now invoke Emacs like this:

    $ emacs -Q -l ~/fill-column.el

Now fill the *scratch* message with M-q. To me it gets
very thin: 15 chars.

Right, the more often you use the shortcuts the closer
and shorter you want them to be. Default Emacs isn't
bad at this. Most of the really frequent things are
close and short: `forward-word' is M-f,
`backward-word' M-b, `forward-char' C-f,
`backward-char' C-b, and so on.

Thanks, Emmanuel, that worked just fine.  I also tried changing
the setq-default in my init file to plain setq, and everything
worked fine.  Now I have to go through my init file and fix any
misused setq-defaults.  *sigh*  (My goal in using the hook was to
keep the fill-column limited to those modes derived from
text-mode.  I.e., I didn't want it to affect fundamental-mode.)

All these years of using Emacs, and I'm still pretty much a tyro
at Elisp.  Ah well, I learn.  Slowly, maybe, but I learn.

OK, first F6 is a *very bad* key for that! Try M-q
which is the default keystroke for `fill-paragraph'.

Second, your code should work what I can see!

Try starting Emacs like this:

    $ emacs -Q

Then find your init file and evaluate only this part:

    (global-set-key [f6] #'fill-paragraph)

Last, hit F6. Still no luck?

Also, you do this in X, right? Either in a terminal
emulator (e.g., xterm) with -nw or the GUI Emacs
(normal invocation these days) and F6 should be fine.
In a Linux VT tho without special attention F6 doesn't
work. And the reason it hasn't received such attention
is, again, it is a bad key (too distant: out of hand
touch type position).

Actually, Emacs offers at least 2 separate wrap-related features you
may wish trying:

  . M-x auto-fill-mode RET
  . M-x visual-line-mode RET

Thanks, Eli.  I did look at those but put them aside for a serious read
later.
