Wait for compile to finish

Wait for compile to finish

[Toto]

Greetings!

My problem is the following:

I would like to have a function, which runs the program, that belongs to
the buffer i'm editing or compile it first if it isn't done already.
To make it more clear. Say, i'm editing helloworld.c and i call this
function, it should execute helloworld.exe (yes, i'm on windows). If
there is no hello.exe in the current directory (or it is older than the
source file) emacs should compile it first and run it afterwards.

For this purpose I have come up with a funcion similar to the one below.

But: Compile is asynchronous, so this funcion tries to execute the exe
file before the compilation finishes (and the exe is created).

My question is:
Is there a synchronous version of compile? Or how can i determine that
compile has finished (and get the result of the compilation - success
or failure)?

The (pseudo) code is as follows:

(defun run-compiled-program (params)
  "Runs the program with the same name as the buffer."
  (interactive "sRun with parameter(s): ")
  (setq exe (concat
			 (file-name-sans-extension (buffer-file-name))
			 ".exe"
			 )
		)
     (if (not (file-newer-than-file-p exe (buffer-file-name)))
 	 (compile-this-buffer) ;; using the compile funcion
 	  )
  (shell-command
   (concat exe " " params)
   )
  )
;; GNU Emacs 22.0.50.1 (i386-mingw-nt5.1.2600) of 2005-03-08 on S8472


Any suggestions are welcome.

Ps.: my english might not be the best ;)

Use the make utility to compile your program before you run it:

(defun run-buffer-program (&optional args)
   "Compile the visited file into a program and run it with command line 
ARGS."
   (interactive "sArgs: ")
   (let ((program (file-name-sans-extension
                   (file-name-nondirectory buffer-file-name))))
     ;; What is the list of systems that require the .exe extension?
     (when (memq system-type '(dos))
       (setq program (concat program ".exe")))
     (shell-command (format "make %s && ./%s %s" program program args))))

This part is bogus, on several accounts.  First, there's no
system-type `dos' in Emacs, only `ms-dos'.  Second, Windows
executables also have the .exe extension.  And third, there's no need
to append the extension, since Make will DTRT on these systems even
without the .exe.

For this purpose, you might be interested in this:

Personally I use a shell script "mr" and run that instead of "make"
from M-x compile, it does a compile and runs if successful.  You get
compile errors and program output both in the compilation buffer.

If you really want to know in elisp when M-x compile finishes, have a
look at makeinfo-compile in makeinfo.el which does that sort of thing,
but it's not too pretty.

You can set the variable compilation-finish-function to a function.

"Documentation:
Functions to call when a compilation process finishes.
Each function is called with two arguments: the compilation buffer,
and a string describing how the process finished.

Defined in `compile'."

That's close enough.
Thanks.
