Struct PaneGrid 

pub struct PaneGrid { /* private fields */ }

Live grid + cursor + the parser that feeds them. Owns mutable state, so callers wrap it in Mutex (the InProcess does this since multiple PTY-reader threads + the RPC dispatch thread all race for it).

Implementations

impl PaneGrid

pub fn modes(&self) -> ModeSet

Every terminal mode this pane is in, taken at ONE instant.

This is how a client reads a mode under docs/SHUKEN.md — from the authority, never from a parser of its own. Today mado reads bracketed_paste from its OWN Terminal, which is correct only because mado still parses every byte; it becomes a live bug the instant this grid is authoritative, and it is a paste-sanitisation decision, not a cosmetic one.

Returned as a whole ModeSet rather than one getter per mode so a client cannot mix modes from two different instants.

pub fn snapshot(&self) -> PaneSnapshot

pub fn title(&self) -> Option<&str>

Current window title (OSC 0 / 2). None until the first title set; cleared on RIS.

pub fn stamp_yurai(&mut self, y: Yurai) -> bool

Stamp the owning pane’s provenance so every block this grid mints records WHO ran it. Write-once; returns true if this call took effect.

Provenance enters through the grid deliberately. Under shuken (docs/SHUKEN.md) PaneGrid is the sole VT authority — it is the one place that sees the byte stream and mints blocks from it — so attribution belongs at the same seam as the authority. A second, parallel path that attributed blocks anywhere else would be exactly the duplicated-state split shuken exists to forbid.

pub fn yurai(&self) -> &Yurai

Provenance every block from this grid carries.

pub fn cursor_keys_mode(&self) -> bool

DECCKM (DEC mode 1) cursor-keys application mode.

Consumers translating host keystrokes to PTY bytes (mado’s keybind::madori_key_to_pty_bytes, any future tear-client renderer) read this to encode Up/Down/Right/Left as ESC O A/B/C/D (true) or ESC [ A/B/C/D (false).

pub fn scrollback_len(&self) -> usize

Number of scrollback rows that have rolled off the primary screen. Useful for tests + UI affordances.

pub fn resize(&mut self, cols: usize, rows: usize)
