Status
Runnable today:
| API | Return | Notes |
|---|---|---|
std.args.len() | usize | Returns the process argument count. |
std.args.get(index) | Maybe<String> | Returns the argument at index when present. |
Current limits:
- Iterator-style argument APIs.
- Typed decoding helpers.
- Target diagnostics for platforms without process arguments.
Example
pub fun main(world: World) -> Void raises { let count = std.args.len() let first = std.args.get(1) if count > 1 && first.has { check world.out.write(first.value) check world.out.write("\n") }}Design Notes
The module is hosted-only. Freestanding, edge, and embedded targets should reject it unless they explicitly provide an argument capability.
On native Windows-style targets, std.args is byte-oriented process input. It
is not a Unicode argv normalization layer.
Programs that need portable argument semantics should keep target-specific decoding outside the target-neutral core.
