stack ()
A list of all of the functions called up to this point in the execution of the Gamma program.
A function that calls stack is presented in order, with the most recently called function at the end of the function list. stack can be useful for debugging programs by requesting a stack trace when an error occurs.
The following program:
#!/usr/cogent/bin/gamma function hms_to_sec(hms) { hms = list_to_array(string_split(hms, ":", -1)); (number(hms[0]) * 60 + number(hms[1])) * 60 + number(hms[2]); stk = stack(); } tocheck = list(12,5,13); hms_to_sec("tocheck"); princ(stk,"\n");
Yields these results:
((hms_to_sec tocheck) (progn (setq hms (list_to_array (string_split hms : (neg 1)))) (+ (* (+ (* (number (aref hms 0)) 60) (number (aref hms 1) )) 60) (number (aref hms 2))) (setq stk #0=(stack))) #0#)
