Hi:

I'm trying to start some processes and connect them using pipes with ABCL (like Unix shell pipes). I've reviewed the documentation but I haven't found anything. Are I missing something? If not, are there any plans of adding input, output and error parameters for run-program (like SBCL, CCL, etc.)?

There's a function like that in run-program.lisp:

[ snip ] This makes me discover RUN-PROGRAM: CL-USER(1): (apropos 'run-program) SYSTEM:RUN-PROGRAM (fbound) RUN-PROGRAM The following returns the required documentation for me: CL-USER(2): (documentation #'system:run-program 'function) "<text I pasted for you before>" Hope that helps you consult the docs! -- Bye, Erik. http://efficito.com -- Hosted accounting and ERP.

Thankyou, I've seen the documentation before sending my original mail :) I tryed to make a simple pipe with this piece of code:

(let ((p1 (system:run-program "echo" '("zero") :wait nil)) (p2 (system:run-program "grep" '("zero") :wait nil))) (setf (system:process-input p2) (system:process-output p1)) (system:process-wait p1) (system:process-wait p2))

Unfortunately, I don’t think that the ABCL API currently supports such redirection although the docs misleadingly imply that such a thing should be possible . ABCL 1.x is implemented to the Java 5 JVM API, for which the underlying [ProcessBuilder][1] object does not support input/output output stream redirection. The [Java 7 API][process-builder-java7] supports such redirection, so you could implement the necessary abstractions using either the low-level Java Function Interface or the higher-level JSS contrib as long as your target runtime platform was Java 7 or better. In general, the ABCL implementation could use a strategy for supporting such useful primitives when they are available in the underlying platform. Out of curiosity, is anybody actually running ABCL on Java 5 at the moment? Oracle has designated Java 5 as obsolete at this point, but it is probably still in use in legacy enterprise situations where migration is not possible for one reason or another. In my opinion, if we were to make a leap, I would probably skip Java 6, and go straight to Java 7, as there is much greater gain for the pain in the subjective terms of useful APIs.

It has happened before but there is nothing to compare to it now." _______________________________________________ Armedbear-devel mailing list Armedbear-devel@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

Finally I've solved the problem using threads [3] (from bordeaux-threads) :) BTW, now I have a problem when using CL+SSL that seems the ticket 355 [1] and 251 [2]. I'll be waiting for good news about that issues :) Greets and thanks again. Rafael J. Alcántara Pérez.
