Hi folks,
In src/interp/vmlisp.lisp you have:
#+:sbcl
(defun OBEY (S)
#-:win32 (if *OBEY-STDOUT*
(sb-ext::process-exit-code
(sb-ext::run-program "/bin/sh" (list "-c" S) :input t
:output *standard-output* :error *standard-output*))
(sb-ext::process-exit-code
(sb-ext::run-program "/bin/sh"
(list "-c" S) :input t :output t :error t)))
#+:win32 (sb-ext::process-exit-code
(sb-ext::run-program "sh"
(list "-c" S) :input t :output t :error t :search t)))
You will remark I added some of your code for notebook support in my
FriCAS copy, here *OBEY-STDOUT*
The ')system' command uses it, but it is also accessible from SPAD via
the OBEY Lisp function instead.
In your jfricas code (webspad.lisp), you have
(defvar webspad-stream (make-string-output-stream))
and use above instead of
:output *standard-output*
:output webspad-stream
And finally use (get-output-stream-string webspad-stream) to return it.
That way you will even use the FriCAS GC.
I guess you will obtain an SExpression that has a 'string' operation
for coercion.
That can even be done in a '.fricas.input' startup file to rewrite the
OBEY LISP function for example.
Cheers,
