controlling window-configuration changes

[knubee]

 i realize that questions about window configurations are faqs, but i
have not been able to find an answer to this particular question.

i tend to split my emacs frame so that there are two buffers side by
side (C-x 3). this works fine, but there are some applications that
insist on using the entire emacs frame when they are invoked (org-mode
agenda view, TOC for latex files, etc.)

is there a way to specify that all apps respect the vertical boundary
of the current window? or does this require configuring something for
each of the offending apps?

related question: when using moinmoin mode with screen-lines.el, long
lines are wrapped appropriately if the window is the size of the full
emacs frame. But dividing the frame into two side-by-side windows does
not work. Then, the lines of text have the right-facing arrows (to
indicate that the lines continue beyond the right-hand edge). Is there
a way to fix this (or some other utility for long lines) that will
respect the edge of the window?

thanks.

Try setting truncate-partial-width-windows to nil.

ah, great! thanks.

how do i set it to only work for moinmoin mode? i tried the following,
but no success:

(add-hook 'moinmoin-mode-hook 'truncate-partial-width-windows nil)

add-hook need a function, not a variable. See

   C-h f add-hook RET

thanks for the pointer.

i tried:

  (defun my-truncate ()
     (setq truncate-partial-width-windows nil))

  (add-hook 'moinmoin-mode-hook 'my-truncate)

this "works" -- but only in the sense that all buffers and modes now
treat truncate-partial-width-windows as nil. which seems equivalent to
just setq'ing it at the global level. so i also tried:

 (add-hook 'moinmoin-mode-hook '(lambda () (setq truncate-partial-
width-windows nil)))

this does not seem to work.

is using add-hook even the correct way to restrict this to a mode --
or am i just messing up the definitions?

thanks.

Sorry, I should have checked what you where trying to set.

You have to make the variable buffer local to. Try

(defun my-truncate ()
   (set (make-local-variable 'truncate-partial-width-windows) nil))

Does

(defun my-truncate ()
   (set (make-local-variable 'truncate-partial-width-windows) nil))

(add-hook 'moinmoin-mode-hook 'my-truncate)

do what you want?

ah, that did it! (good also to know about make-local-variable) thank
you both.
