<thread> Internal Library

The <thread> module provides baseline parallel task execution and queue channels.

Import

import thr "<thread>"

Metadata

• name: "thread"
• available: runtime support flag
• platform: "windows" on Windows builds, otherwise "stub"
• version: internal module version string

API

• spawn_native(job_name, ...args) -> int
• join(task_id, timeout_ms?) -> any
• is_done(task_id) -> bool
• sleep(ms) -> bool
• yield() -> bool
• cpu_count() -> int

Channels

• channel_create(capacity?) -> int
• channel_send(channel_id, value) -> bool
• channel_recv(channel_id, timeout_ms?) -> any | none
• channel_size(channel_id) -> int

Baseline Pool Aliases

• pool_submit(job_name, ...args) -> int
• pool_join(task_id, timeout_ms?) -> any

Current baseline pool APIs map to the same task backend as spawn_native and join.

Built-in Jobs

• sum: sums numeric arguments
• sleep_ms: sleeps and returns true
• echo: returns first argument

Example

import thr "<thread>"

var ch = thr.channel_create(4)
thr.channel_send(ch, 42)
display(thr.channel_recv(ch))

var id = thr.pool_submit("sum", 1, 2, 3)
display(thr.pool_join(id, 2000))  ## 6
