truncating long lines

truncating long lines

[Jay Cotton]

I am trying to use 2 side-by-side windows in emacs, and I don't want it 
to truncate long lines.  However, when I use the command m-x 
toggle-truncate-lines, nothing happens.  If I am just using one window, 
the command works as expected, but with 2 vertical windows if seems to 
have no effect.

Anybody know how to accomplish this?

This truncate you are talking about is breaking the line when it reaches
a specific column? if it is, you must try setting off the
auto-fill-mode:

M-x auto-fill-mode

,----[ C-h f get-buffer RET ]
| auto-fill-mode is an interactive compiled Lisp function in `simple'.
| (auto-fill-mode &optional ARG)
| 
| Toggle Auto Fill mode.
| With arg, turn Auto Fill mode on if and only if arg is positive.
| In Auto Fill mode, inserting a space at a column beyond `current-fill-column'
| automatically breaks the line at a previous space.
| 
| The value of `normal-auto-fill-function' specifies the function to use
| for `auto-fill-function' when turning Auto Fill mode on.

I think you want to fiddle with the variable
truncate-partial-width-windows.

Actually, auto-fill-mode is not turned on.  The 'truncation' that I'm 
referring to is when emacs puts a dollar sign ($) at the end of each 
row to signify that there is more text and you will need to scroll 
horizontally in order to see it.  When you are programming, you can 
turn this on and off with the command m-x toggle-truncate-lines.  
However, this command does not appear to work when you are have two 
side-by-side windows.  (I achieve this window arrangement with the 
command c-x 3.)  Instead, the line truncation appears to be always on, 
and the command m-x toggle-truncate-lines executes but nothing changes.

(setq truncate-partial-width-windows nil)

then M-x toggle-truncate-lines to your heart's content
