Readme
[!WARNING] Do not install anything here yet.
This is a fast-moving prototype: the interfaces change without notice, and nothing here is stable. Every package in this project is headed for a stable 1.0, but that is still some way off. Install one only if you intend to follow the code and expect breakage.
@tinoy/pi-ipc
Talk to other pi sessions on this machine: list the peers, send to one, ask one and wait for its answer, or broadcast to all of them.
pi install npm:@tinoy/pi-ipc
What it needs at call time
A writable $XDG_RUNTIME_DIR, which a login session provides. The transport lives under
$XDG_RUNTIME_DIR/pi-ipc and is refused by name when that directory is unset, is not a directory,
or belongs to another user — it never falls back to a second location. There is no broker, no
socket, no config file and no command line: the transport is reachable only from an extension
running inside a session, and a session's id and name come from the session itself.
Registers
ipc
| Action | What it does |
|---|---|
list |
the live sessions, each with a short id, name and cwd |
send |
one message to one peer, arriving in it as a turn of its own |
ask |
send, then block until the peer answers or the ask times out |
broadcast |
the same message to every other live session |
A peer is addressed by its full session id, a unique id prefix of 4 or more characters, or its
exact name; a target that could be more than one session is refused with the candidates. An inbound
ask prints the handle that answers it — only an ask carries one, so a message or broadcast is never
answered with answerTo — and a handle that matches no waiting ask delivers its text as an ordinary
message rather than dropping it. An ask left unanswered is named in one line at the end of
the turn — there is no pending action to poll. PI_IPC_ASK_TIMEOUT_MS sets the ask timeout
(default 600000 ms).
Works better with
| Neighbour | You gain | You lose without it | Install |
|---|---|---|---|
@tinoy/pi-canon |
a canon edit reaches every running session as a passive notice, with no new session needed | running sessions keep the rules they started with until they are restarted | pi install npm:@tinoy/pi-canon |
@tinoy/pi-focus-gate |
a focus toggle reaches every peer as a passive notice at its next turn | each session still reads the state file, so gating is unaffected and only the notice is lost | pi install npm:@tinoy/pi-focus-gate |
The bus is the same contract either way: a package that registers a namespace still serves it with this package installed or with any other implementation of the transport.
Dependencies
pi-supplied imports (@earendil-works/pi-coding-agent, typebox) are peer dependencies with a *
range and are never bundled. Plain dependencies: @tinoy/pi-ext-lib, whose ipc.ts owns the wire —
the rendezvous path, the presence records, the inbox and the bus contract strings.
