How to defun body in procedural manner

How to defun body in procedural manner

[Kiwon Um]

Hello. I wrote a function as follows:

(defun my-update-package (path)
  "Update the package in path from CVS"
  (cvs-update path nil)
  (shell-command (concat "touch `find " path " -name Makefile`"))
  (compile (concat "make -C " path)))

When the function is called, it seems to execute the shell-command and
compile lines before the finishing cvs-update line. How can I make
this functional execution procedurally? Help me, please.

Thanks.

Lisp does execute procedurally.  The problem is that cvs-update starts a 
background process to do the work, and then returns.

Thanks for your reply. So how can I check the return time of the
background process?

Hi, i don't use cvs, but you should have a look at what return:
`cvs-sentinel'.
and:
(when (cvs-sentinel ==> return_what_you_want)
  (shell-command "your_command"))

I've tried to understand what the cvs-sentinel function does, but I
didn't. Would you write a concrete example code for me, please?

Yes, as i told you i am not a cvs user, so...
it seem cvs-sentinel return only a message :-(
So try that, i just write it and it worked to update emacs-w3m and compile
it:

(defun update-cvs-dir-and-compile ()
  (interactive)
  (let ((dir default-directory))
    (cvs-update dir nil)
    (while (not (equal cvs-mode-line-process "exit"))
      (sit-for 1))
    (shell-command "make")))

Modify for your need (make args ...etc..)

These codes work very well. Thanks. :)

Then, how can I check the end of the compile process as similar manner
as above? I tried (compile-mode-line-process "exit"), but it didn't
work. And I tried as follows:
(while (not (equal (process-status  "compilation") 'exit)) (sit-for
1))
This didn't work, either.
Any advice?

`shell-command' is a synchronous process, so you have just to wait it
finish.May be just add a message to tell you that the compile process is
started:

(defun update-cvs-dir-and-compile ()
  "Cvs update current dir and compile it."
  (interactive)
  (let ((dir default-directory))
    (cvs-update dir nil)
    (while (not (equal cvs-mode-line-process "exit"))
      (sit-for 1))
    (message "Wait compiling %s..." dir)
    (shell-command "make")))

But if you want to run the compile process asynchronous,
you have to use `start-process' instead of `shell-command' and set a
sentinel on this process like this:

(progn
  (start-process "my-compil" nil "sleep"
               "12")
  (set-process-sentinel (get-process "my-compil")
                        #'(lambda (process event)
                            (message "Process:%s State:%s" process event))))

Replace "sleep" with "make" and "12" with make args ;-)

NOTE:If you have more than one arg to the make command, it's may be
convenient to use apply on start-process.

If you want be able to run more than 1 process (after all, it is
asynchronous):

(let ((this-process (start-process "my-compil" nil "sleep"
				   "12")))
   (set-process-sentinel this-process
                         #'(lambda (process event)
                             (message "Process:%s State:%s" process 
event))))

Ah! I missed my point. Actually, I've changed shell-command to compile
so that
(compile "make -C ...some_path") not (shell-command ...).
The function 'compile' doesn't seem to be synchronous, huh? So I'm
wondering how to check it.

compile is asynchronous, and it will warn you when finish.
Have a look at C-h f compile RET.

Unless you have to run another command after the compile process, there
is no need to catch the end of the process, just wait it warn you in the
mode-line or the compile buffer.
