Cause procedure to be "traced", that is debugging output will be written to the standard error port every time procedure is called, with the parameters and return value.
Note that Kawa will normally assume that a procedure defined with
the procedure-defining variant of
define is constant,
and so it might be inlined:
(define (ff x) (list x x)) (trace ff) ;; probably won't work (ff 3) ;; not traced
It works if you specify the
--no-inline flag to Kawa.
Alternatively, you can use the variable-defining variant of
#|kawa:1|# (define ff (lambda (x) name: 'ff (list x x))) #|kawa:2|# (trace ff) ;; works #|kawa:3|# (ff 3) call to ff (3) return from ff => (3 3) (3 3)
Note the use of the
name: procedure property to give the
lambda a name.
Turn off tracing (debugging output) of procedure.
Returns a string representation of the disassembled bytecode for procedure, when known.
