range

#define range(...)

Construct a Range object on the stack.

Examples

Usage

/* Iterate 0 to 10 */
foreach (i in range($I(10))) {
  print("%i\n", i);
}

/* Iterate 10 to 20 */
foreach (i in range($I(10), $I(20))) {
  print("%i\n", i);
}

/* Iterate 10 to 20 with a step of 5 */
foreach (i in range($I(10), $I(20), $I(5))) {
  print("%i\n", i);
}

/* Iterate 20 to 10 */
foreach (i in range($I(10), $I(20), $I(-1))) {
  print("%i\n", i);
}

Range

Integer Sequence

The Range type is a basic iterable which acts as a virtual sequence of integers, starting from some value, stopping at some value and incrementing by some step.

This can be a useful replacement for the standard C for loop with decent performance but returning a Cello Int. It is constructable on the stack with the range macro which makes it practical and easy to use.

Definition

struct Range {
  var value;
  int64_t start;
  int64_t stop;
  int64_t step;
};
