Treatment spawnOnce

process/local::spawnOnce

Parameters

↳ var command: Command (process/command::Command)
↳ var environment: Option<Environment> = _ (process/environment::Environment)

Inputs

⇥ launch: Block<void>
⇥ stdin: Stream<byte>

Outputs

↦ completed: Block<void>
↦ error: Block<string>
↦ exit: Block<Option<i32>>
↦ failed: Block<void>
↦ finished: Block<void>
↦ started: Block<void>
↦ stderr: Stream<byte>
↦ stdout: Stream<byte>

Spawn a single command on the local machine with stdio streams, triggered by a launch signal.

Convenience wrapper around spawnOnce that automatically obtains the local executor. command is spawned with the optional environment when launch fires. Connects stdin, stdout, and stderr streams to the process. started, completed, failed, error, exit, and finished behave identically to spawnOnce.
