std.proc

Host process status helpers behind explicit process capability boundaries.

Status

Runnable today:

APIReturnNotes
std.proc.spawn(command)ProcStatusCreates a process status through the explicit proc capability surface.
std.proc.exitCode(status)i32Reads the process status code.

Metadata labels:

  • effects: proc
  • allocation behavior: no allocation
  • target support: host
  • error behavior: spawn returns ProcStatus; exitCode is infallible
  • ownership notes: no ownership transfer in the current status model
  • example: examples/std-platform.0

Example

pub fun main(world: World) -> Void raises {    let status = std.proc.spawn("zero-noop")    if std.proc.exitCode(status) == 0 {        check world.out.write("proc ok\n")    }}

Design Notes

std.proc is host-only. Cross targets without process support must reject process helpers before code generation.

They should not compile a placeholder process implementation.
