Module subprocess 

Interactive subprocess I/O (spawn + piped stdin/stdout).

Windjammer std::subprocess maps here. Uses opaque handles so backends can swap implementation without changing the WJ API.

Structs

SubprocessHandle

Opaque handle returned to Windjammer (Subprocess.handle).

Functions

close

frames_in_agent_command

Parse frames=N from an agent CMD payload (default 1).

invalid_handle

is_valid

kill

read_agent_obs_n

Read N @AGENT OBS lines; returns the payload of the last one (no prefix).

read_line

read_line_until_prefix

Read lines until one starts with prefix (e.g. @AGENT OBS).

spawn

Spawn a program with piped stdin/stdout (stderr inherits to host). A background thread drains stdout so game init logs cannot deadlock the pipe.

wait

write_line
