libghostty 0.0.3

Dart FFI bindings to libghostty-vt, the VT emulator library from Ghostty.

Changelog

0.0.3

Added

• iOS simulator support: prebuilt binaries for aarch64-ios-simulator and x86_64-ios-simulator.

Fixed

• Asset hash validation: reject prebuilt binaries with no known hash instead of silently accepting them.

0.0.2

Added

• Sealed TerminalEvent hierarchy: typed events (BellReceived, TitleChanged, CursorChanged, MouseShapeChanged, ResponseReceived, ScreenChanged, ModeChanged) replace ad-hoc state polling.
• TerminalOptions: configure foreground/background color and scrollback limit at terminal creation.
• Mouse support:MouseShape and MouseTracking exposed via the terminal API.
• DirtyState enum:clean/partial/full for render-level dirty tracking on Screen.
• Reusable viewport buffer:Screen reuses a single buffer across reads, reducing per-frame allocations.
• Row wrapping detection:Screen and Scrollback report whether a row is soft-wrapped.
• Scrollback grapheme support:Scrollback returns full grapheme clusters.
• CellWidth and SemanticContent: new cell metadata types.
• 256-color palette: CIELAB interpolation and full 256-color palette generation with base16 theme support.

Changed

• TerminalViewport removed: viewport reading now lives on Screen directly.
• Bumped upstream ghostty to 055ed285.
