Emacs Lisp - buffer name as part of compile-command
Hello,

I'm trying to setup GNU emacs to do some SIMPLE java work for me.

I'm working in a given folder, and want to just edit and compile programs in this one folder.

In my .emacs, I have:

Code:
(setq compile-command (concat "javac " (buffer-name)))



I cd to the folder, and run emacs sample.java

I edit the file, and then in emacs, I M-x compile.

The problem, is that in the minibuffer, it shows:
Compile command: javac *scratch*

instead of javac sample.java

Why is this? The buffer *scratch* is (by default) open, but is NOT in the one visible window - sample.java is.

How to I get this to use the correct buffer name for the active buffer?

An answer to this question was posted on LinuxQuestions.org thanks to user "ntubski".

His post was as follows:
Quote:
The problem is that compile-command gets set when the your .emacs is loaded, what you need to do is add a hook that will run every time you open a java file:

Code:
(add-hook 'java-mode-hook
	  (lambda()
	    (set (make-local-variable 'compile-command) (concat "javac " (buffer-name)))))
