Per-directory customizations?

Per-directory customizations?

[Roy Smith]

Is there any way to do customizations on a per-directory basis?

For example, I've got java project which lives in ~/dev/foo.  Anytime I 
run M-X compile anywhere inside the ~/dev/foo hierarchy, I want the 
command run to be "cd ~/dev/foo; ant".  I don't want to just set 
compile-command in my .emacs file, because the right command varies 
depending on which project (i.e. directory subtree) I'm in.

Is there any way to do this?  I'm running GNU Emacs 21.2.1.

I do something similar, with defadvice of compile-internal, and
setq compile-command depending on default-directory.

http://www.emacswiki.org/cgi-bin/wiki.pl/DirVarsPackage

With the dirvars.el package you create a file called .emacs-dirvars in
the root directory containing

    compile-command: "cd ~/dev/foo; ant"

Then this setting is automatically used by the root directory and all
subdirectories.


I use the following to store the current compile-command in a
.emacs-dirvars file.

    (defun vjo-create-dirvars-file (cmd)
      (interactive)
      (if (file-exists-p ".emacs-dirvars")
          (progn
          (find-file ".emacs-dirvars")
          (goto-char (point-max)))
        ;; else
        (progn
          (find-file ".emacs-dirvars")
          (insert ";; -*- emacs-lisp -*- \n")
          (insert ";; VJ\n")
          (insert (concat "compile-command: <QUOTE>" cmd "<QUOTE>\n"))
          (replace-string "\"" "\\\"" nil (previous-line 1) (point))
          (replace-string "<QUOTE>" "\"" nil (previous-line 1) (point))
          (save-buffer))))

Why not set compile-command in the mode hook, as suggested in it's doc
string:

(add-hook 'java-mode-hook
	  (lambda ()
	    (when (string-match "\\`~/dev/foo/" default-directory)
	      (set (make-local-variable 'compile-command)
		   "cd ~/dev/foo; ant"))))

The problem there, is it only works for java files.  I've got all sorts 
of files in my project directory tree (html, css, jsp, etc, etc).  I 
want the compile command tied to the directory tree, not the file type.

In sml-mode.el, I made the sml-compile command walk up the directory tree
until it finds the Makefile-equivalent.  Maybe M-x compile RET should do
the same: walk up the tree until it finds a Makefile and then use
"cd ../..; make".

The use find-file-hooks instead of jave-mode-hook.

There is another way, using

(setq compile-command
      '<lisp expression that evaluates to a string>)

like

(setq compile-command
      '(cond ((string-match "\\`~/dev/foo/" default-directory)
	      "cd ~/dev/foo; ant")
	     (...)
	     ...
	     (t "make -k")))

etc.

This won't work if he uses dired, gnus, man, etc... while in
~/dev/foo/.

I don't see any reason why not.  Care to explain?

find-file-hooks isn't called for a (dired "~/dev/foo/") buffer,
so compile-command won't be customized for the dired buffer, and
so M-x compile in that buffer won't do what he wants.
