Hook problem

Hook problem

[Faredoon Irani]

Hi,

	I've installed a hook function for the 'after-change-functions' 
hook since I would like to process each and every key pressed. The problem 
is that I do not want to process anything through the hook function if 
the result of a key press accesses the minibuffer, for e.g. C-x C-f. 
This results in the processing of all characters displayed in the 
minibuffer also! I have tried to use minibuffer hooks to toggle a variable 
value when the minibuffer is entered and exited, but the key hook is being 
processed much earlier. Please help.

add-hook has an argument that allows you adding to a buffer-local
value of the hook.

You could also, in your buffer, say
(make-local-variable 'after-change-functions)
before adding to it, but in versions of Emacs where add-hook can
support buffer-locals, that would be the preferable option.
