Subject: Waiting for Asynchronous Process
Date: Mon, 25 Aug 2008 15:11:57 -0700 (PDT)	[thread overview]
Message-ID: <089da2d2-c201-48ea-b49e-21966e4637f8@i76g2000hsf.googlegroups.com> (raw)

Suppose I'm writing a function that will compile 4 files (A, B, C, and
D). The first three can compile in any order, but D must come last.
I want the user to have a responsive Emacs while the compilations are
going on.

I could do (call-process "theCompiler" .... "A")
               (call-process "theCompiler" .... "B") ...
but then Emacs is "frozen" until all files are compiled.

I could do (start-process ...), but then I can't seem to wait for the
processes to all exit without causing Emacs to hang.

I know that ELisp doesn't do multithreading. Is it possible to do what
I want without creating a separate script outside of Emacs?
