Comes with no examples of Asteria source code about asteria

Also better prefer standalone translation units over embedded code in test cases.

As we speak there are quite a few standard library components left unimplemented (std.math, std.io etc.) but most of the core language features are almost complete. There will be examples once these are finished.

At the moment, the only output functions are std.debug.print() and std.debug.dump() (which write the standard error stream); no input functions are available. A few samples are:

// hello world

std.debug.print("hello world!");

// calculate the sum of integers 1, 2, ..., 100

var sum = 0;
for(var i = 1; i <= 100; ++i) {
  sum += i;
}
std.debug.print("sum = ", sum);

// sort an array from smallest to largest

var data = [ 5, 2, 9, 7, 3, 1, 6, 4, 8, 0 ];
data = std.array.sort(data);
std.debug.print("sorted = ", data);

// sort an array from largest to smallest

var data = [ 5, 2, 9, 7, 3, 1, 6, 4, 8, 0 ];
data = std.array.sort(data,
  /* closure function */ func(x, y) { return y <=> x;  }
  /* alternatively:   func(x, y) = (y <=> x)  */
);
std.debug.print("sorted = ", data);

// object-oriented programming

/* struct foo {
 *   integer value = 42;
 *   integer get() { return this.value;  }
 *   void inc() { this.value += 1;  }
 * }
 */

func foo_new() {
  return {
    value = 42,
    get = func() { return this.value;  },
    inc = func() { this.value += 1;  },
  };
}

var p = foo_new();
std.debug.print("p = ", p);
std.debug.print("p.get() = ", p.get());  // 42
std.debug.print("p.inc() = ", p.inc());  // null
std.debug.print("p.get() = ", p.get());  // 43

// exception handling

func times_1000(x) {
  return x * 1000;
}

try {
  var y = times_1000(12345678901234567);
  std.debug.print("y = ", y);
} catch(e) {
  std.debug.print("caught exception: ", e);
  std.debug.print("  backtrace: ", __backtrace);
}

Those are not feasible until the REPL is finished.

I like the examples. Thank you

[lhmouse]

I will create a new issue for the REPL then.
