Subject: Example of run-process with redirection to pipe?
Date: Fri, 23 Aug 2019 17:53:00 -0000 [thread overview]
Message-ID: <12176.1566582795@localhost> (raw)
I am probably missing something obvious but I cannot seem to figure out
how to use run-process with output redirected to a pipe.
Based on my reading of the manual, I have:
(let ((p (run-process "echo Hello"
out-to: 'pipe)))
(p:getInputStream))
but it give an error (full trace below) that I can't quite interpret:
java.lang.IllegalAccessException: Class gnu.expr.PrimProcedure can not
access a member of class java.lang.UNIXProcess with modifiers "public"
I would be grateful if someone could point me to some code illustrating
the use of the pipe feature of run-process.
Regards,
-chaw
