doc.go RawHistoryFolder

1// Package vt implements the server-side terminal emulator core.
2//
3// It tracks the visible cell grid, damage rectangles, scroll regions,
4// alternate-screen state, cursor/reporting modes, and common xterm/VT control
5// sequences. Wide runes that fit are stored as a head cell plus a continuation
6// cell, and resize or edit operations repair row-boundary splits instead of
7// leaving orphaned halves.
8//
9// Screen is single-owner. Snapshot returns an owned capture of the active
10// visible viewport and renderer-relevant metadata; callers must serialize it
11// with Write, Resize, and host mutations. Terminal history remains available
12// through HistoryView and HistorySnapshotView rather than ScreenSnapshot.
