Crate tear_core 

tear-core — runtime logic for the tear multiplexer.

Houses the session/window/pane state machine, PTY ownership (portable-pty), the layout engine, and the InProcess implementation of tear_types::MultiplexerControl.

Why this matters for the mado integration

mado currently owns its own pane.rs/tab.rs with private state machines. At M5 those modules rebase onto tear-core::InProcess — both apps then share one source of truth for pane semantics. This crate’s InProcess impl is the gravitational center the eventual rebase lands on.

No daemon — those live in tear-daemon. Daemon-side composition wraps InProcess rather than reimplementing.

Modules

blocks

Pane-as-block — OSC 133 prompt-mark-driven block extractor.

inproc

InProcess — the in-memory tear_types::MultiplexerControl implementation backed by parking_lot::RwLock<Registry> + BTreeMap<PaneId, PtyHandle>.

pane_grid

Per-pane terminal cell grid driven by a vte parser.

pty

PTY ownership — one PtyHandle per running pane.

reap

The typed admission ticket for daemon-initiated session removal.

recording

Per-pane recording — captures every PTY byte with a relative timestamp, exposes a ring-buffered snapshot, and exports as asciinema v2 .cast (JSON-lines) so any external player handles playback. Daemon-native: no asciinema rec wrapper needed.

registry

In-memory session/window/pane registry — the typed state machine every crate::InProcess op composes against.

Structs

Block

Re-export the wire shape so callers don’t have to choose between tear-core and tear-types — they’re the same type.

Cell

One cell in a snapshotted pane. Carries the rendered character

PaneSnapshot

Serializable snapshot of one pane’s visible grid + cursor. Sent over the tear-daemon ↔ tear-client wire so consumers can render without holding a reference into the live parser state.
