A robot-/CLI-addressable control message (FC-2) — the named boundary a headless driver (or the host, or a canvas gesture) drives the console through. Applied by Console::update, which is the only legal way to mutate the ConsoleModel.

Variants

PushLine(String)

The host appends a raw (ANSI) output line to the scrollback (a process’ stdout, a REPL result). Assigns the next stable id and rolls the ring.

SetInput(String)

Replace the whole in-progress input line (e.g. a paste, or a programmatic set).

InputChar(char)

Type a character at the input caret.

Backspace

Delete the character before the input caret.

Submit

Submit the current input: echo prompt+input into the scrollback, record the command in history, clear the input, and emit Effect::RunCommand.

HistoryPrev

Recall the previous (older) history entry into the input.

HistoryNext

Recall the next (newer) history entry — past the newest returns a blank draft.

SelectLine(Option<LineId>)

Select a scrollback line by its stable id (FC-5), or clear with None. An unknown id is ignored (guards against a stale/evicted id).

SetFilter(String)

Set the free-text find filter (searchable).

ScrollBy(f32)

Smooth-scroll the scrollback by a pixel delta.

ScrollTo(f32)

Smooth-scroll to an absolute pixel offset.

ScrollToBottom

Snap the scroll target to the bottom (newest output).

SetScrollMax(f32)

Sync the scroll extent to the laid-out content vs. viewport height. Emitted by the pure view each frame (it is the one layout-derived value the view cannot compute without egui); applied on the next update, so the extent trails the content by one frame (see the crate note).

Tick(f32)

Advance the smooth-scroll animation by dt seconds (injected clock, FC-7).

SetScale(f32)

Set the render scale (clamped to [0.25, 4.0]).

SetCursor(Cursor)

Change the cursor shape.
