cargo.spawn — cargo-cljs 0.1.0

Utilities for spawning processes and managing their lifecycle.

Linux Note: if you spawn a process that spawns its own children, killing the parent will not kill its children and you may be left with a zombie if you are not careful. See kill-r below.

collected-spawn cljs

(collected-spawn cmd args {:keys [key silent? json->edn?] :as opts})

collect CP output as if it were an async exec call, but allow output logging during process execution. Spawns are not persistent but may be long running.

Returns pchan<[ ?js/error ?[exit-code stdout stderr] ]> where stdout/stderr json is automatically converted to edn where applicable. Cargo writes line delimited json to stdout regardless if it represents a clean exit or not. [0 [{:some :stdout} {:more :stdout}] ['some stderr' 'more stderr']
