Basic Argument handling

Let's look at this snippet

#import Std
#import Math
#import Modules

fun int get_ncycles() {
  if(me.args())
    return me.arg(0) => Std.atoi;
  return 2;
}

fun float get_user_duration() {
  if(me.args() > 1)
    return me.arg(1) => Std.atof;
  return 1;
}

fun dur get_duration() {
  return get_user_duration()::second;
}


get_ncycles() :=> const int ncycles;
get_duration() :=> var dur duration;

1 :=> var int compensate;
const SinOsc s ~> dac;

while(duration >= samp) {
  repeat(ncycles * compensate) {
    Math.rand2f(220, 880) :=> s.freq;
    duration => now;
  }
  duration/2. :=> duration;
  2 *=> compensate;
}

Yes, it's almost the same as the previous one, but this one provides argument handling.

For instance this function:

fun int get_ncycles() {
  if(me.args())
    return me.arg(0) => Std.atoi;
  return 2;
}

checks if the file was called with any arguments, using me.args().

If there is at least one argument, we get it as a string, using me.arg(0) since we want the first argument, then we get the int value out of it, with Std.atoi.

If there is no argument, it defaults to 2.
