Jose,
Something I've experimented with, though never put into 'factor.el' is an
electric ';' key.
The ':' is shifted and it's used often. The idea is to overload the ';' key:
If you're not in a word definition, insert ':'
If you are in a word definition, insert ';'
A bare-bones implementation which simply checks if you're at the beginning of
a line is:
(defun factor-insert-colon ()
(interactive)
(if (bolp)
(insert ":")
(insert ";")))
And of course:
(define-key factor-mode-map ";" 'factor-insert-colon)
That's "level one" functionality. :-) Level two is a little wackier:
If you're not in a word definition, insert a word template:
: | ( -- ) ;
The cursor will be placed where the '|' is located. You type the word name. If
you press ';' again the cursor will jump to the effect-in area:
: breatharian ( | -- ) ;
You type some effects:
: breatharian ( diet-coke quarter-pounder| -- ) ;
You press ';' again, you jump to the effect-out area:
: breatharian ( diet-coke quarter-pounder -- | ) ;
Type the out:
: breatharian ( diet-coke quarter-pounder -- 5th-dimension| ) ;
Hit ';' to jump to the word body:
: breatharian ( diet-coke quarter-pounder -- 5th-dimension )
| ;
Enter the body:
: breatharian ( diet-coke quarter-pounder -- 5th-dimension )
"$25,000,000" donate| ;
Finally, hit ';' to jump out of the word:
: breatharian ( diet-coke quarter-pounder -- 5th-dimension )
"$25,000,000" donate ;
|
I don't think this kind of "electric key" behaviour is for everybody, but it
might be worth experimenting with. Definately should be easy to opt out
of. :-) Maybe even be off by default.
Another possibility is using the ']' key to close the current expression (i.e.
it might insert '}' or ']').
We type double quotes a whole lot more often than single quotes. Maybe the
single-quote key should insert a double-quote.
Finally, crazy stuff like 'paredit.el' is also interesting. I.e. navigating
Factor code in semantic chunks.
