a little .emacs, like .htaccess, for subdirectories

a little .emacs, like .htaccess, for subdirectories

[Dan Jacobson]

Well, Apache has .htaccess files for each directory tree, etc.  Any
way to get a already running emacs to know that I want certain options
in effect when I am in this directory, and other options in effect
when I am in that directory?  Sure there are local file variables, but
that is only for one file.

And what about a *compilation* buffer?  I don't think you are going to
get any local variables in there.

Currently my .emacs does
(add-hook 'compilation-mode-hook
           (function (lambda ()
	      (toggle-read-only 1);else I often edit it because it
				  ;looks like my makefile
	      (toggle-truncate-lines); few docs for this
	      (define-key compilation-mode-map "q" 'quit-window))))

I was hoping to have toggle-truncate-lines be in effect in some
directories only.  Must I make some big conditional deal right there
in the hook, having to list which directories I want this on in... or
can I one day maybe have a "little .emacs", say read by emacs the
first time it visits a file in a directory, with items only
applicable to files in that directory... and if I change the little
.emacs, I would tell emacs to re digest it, unless I have autochecking on...

Hmmm, this probably is too much of an agglutination of an idea.

Does http://www.lickey.com/env/elisp/dirvars.el do what you want?

I think the tricky thing is that the *compilation* buffer is a process
buffer that's not visiting a file.  Perhaps the
dirvars-hack-local-variables-hook function could be added to
compilation-mode-hook...
