Hi,
What could I do please to make (ext:system) work with slime?
No problem with CLISP's (ext:shell). No problem with ECL's (ext:system) outside of slime. But when evaluating `(ext:system "ls")' in slime, I get this error:
--8<---------------cut here---------------start------------->8--- :INPUT argument to RUN-PROGRAM does not have a file handle: #<a SWANK-BACKEND::SLIME-INPUT-STREAM> [Condition of type SIMPLE-ERROR]
Restarts: 0: [RETRY] Retry SLIME interactive evaluation request. 1: [*PROCESS-INPUT] Continue reading input. 2: [ABORT] Return to SLIME's top level. 3: [CLOSE-CONNECTION] Close SLIME connection. 4: [RESTART-TOPLEVEL] Go back to Top-Level REPL.

Using latest cvs slime and latest git ecl.
TIA for any help,
ECL should be handling it, not Slime. On Feb 17, 2013 2:10 AM, "Peter Münster" pmlists@free.fr wrote:

Stas Boukarev is right. This is not Slime's problem, but ECL.
The stream arguments passed to EXT:RUN-PROGRAM must have an underlying operating system file handle. What EXT:RUN-PROGRAM does is fork(2) another process with the new process' standard input, output and error streams bound to the file handle of respective streams passed to EXT:RUN-PROGRAM.
This requirement is imposed by ECL's implementation of EXT:RUN-PROGRAM and is not satisfied by SLIME-OUTPUT-STREAM. I have been meaning to extend EXT:RUN-PROGRAM to support arbitrary Common Lisp streams, but I have not got around to doing it.
To get around the problem now, you can do the following:
(let ((*standard-output* ext:+process-standard-output+) (*standard-input* ext:+process-standard-input+) (*error-output* ext:+process-error-output+)) (ext:system "/bin/ls"))
The output of "/bin/ls" will be sent to the *inferior-lisp* buffer.
Thanks Mark
