help with double spaces etc.

[Todd Wylie]

Greetings-

I would really like to be able to have a mode in emacs that would let the user view text in a different manner than emacs saves the buffer ... almost a "revert on save" ability. For example, I would really like to view text in emacs as double-spaced with auto-fill word-wrapping - but to lose the wrapping and line returns when saved.
Are there any libraries that do something like this? I've never written lisp -- is this a very hard thing to write?

Any help would be greatly appreciated....

Thanks-
T.

The "format" feature allows this.  See the variable format-alist.

If you have a shell command which double-spaces a file (well, standard
input) and another un-double-spaces it, then you almost need no Lisp
at all.

I don't know what you mean by "doubble-spaced", but there is a
library name longlines.el that provides the word-wrapping part. I
think it is on the Emacs Lisp List. Or use Google.

For the double-spacing part you can use the variable `line-spacing', 

,----[ C-h v line-spacing RET ]
| line-spacing's value is nil
| 
| Documentation:
| Additional space to put between lines when displaying a buffer.
| The space is measured in pixels, and put below lines on window systems.
`----

This only changes the display, not the file itself.
