stack

Arguments

Returns

A list of all of the functions called up to this point in the execution of the Gamma program.

Description

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.

Example

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#)
