Dear Karim and Didier,
in effect, I just checked on a good old mac that the ‘lisp-code-box’ exists in PWGL. It was probably there in Patchwork, I remember I used it quite soon and often.
The ‘lispfunction’ box in OM has exactly same functionnalities than the ‘code-box’ (whith no lisp-) in PWGL: you can write (only) lambda expressions and inputs connectors are graphically updated according to its arguments list.
But these two kind of way to write lisp code are not equivalent.
In the first way (Patchwork way), one can define lisp functions, methods, etc, not only anonymous functions (lambda).
In the second way, a lambda has to be defined, and all lisp functions defined using, for instance a ‘defun’ statement seems to be not recognized into the patch.
I really like (need) the first way… it is very convenient.
Bests.
