## New `range()` function |
|
|
|
``` meson |
|
rangeobject range(stop) |
|
rangeobject range(start, stop[, step]) |
|
``` |
|
|
|
Return an opaque object that can be only be used in `foreach` statements. |
|
- `start` must be integer greater or equal to 0. Defaults to 0. |
|
- `stop` must be integer greater or equal to `start`. |
|
- `step` must be integer greater or equal to 1. Defaults to 1. |
|
|
|
It cause the `foreach` loop to be called with the value from `start` included |
|
to `stop` excluded with an increment of `step` after each loop. |
|
|
|
```meson |
|
# Loop 15 times with i from 0 to 14 included. |
|
foreach i : range(15) |
|
... |
|
endforeach |
|
``` |
|
|
|
The range object can also be assigned to a variable and indexed. |
|
```meson |
|
r = range(5, 10, 2) |
|
assert(r[2] == 9) |
|
``` |
