termlib 0.6.0

Library that provides a set of utilities for terminal applications.

0.6.0

• breaking: TermLib replaced by sealed Term. Term.open({TermBackend? backend}) returns InteractiveTerm (tty stdin) or PipedTerm (piped stdin); dispatch via pattern matching.
  • poll<T>() renamed to tryEvent<T>(), returns T? (no more NoneEvent sentinel).
  • pollTimeout<T>({int timeout}) renamed to awaitEvent<T>({Duration? timeout}), returns Future<T?> (null on timeout).
  • read<T>() renamed to nextEvent<T>(), returns Future<T> (blocks until matched).
  • stdinStream renamed to stdinBytes, moved to PipedTerm only.
  • Runtime hasTerminal gates replaced by the sealed split: events, raw mode, cursor/erase extensions, probe and readline live on InteractiveTerm — piped misuse is a compile error.
  • TermRunner builds an InteractiveTerm; callbacks receive it typed.
  • terminalOverrides removed — tests inject TermBackend.fake(...) and capture output through a buffered TermSink.
• breaking: Style is immutable — apply(TextStyle) returns a new Style instead of mutating; added copyWith and render(text, {reset}); instances compare by value.
• breaking: the event queue is bounded (drop-oldest) — overflow surfaces as a QueueOverflowEvent; mouse-motion and resize events coalesce at enqueue.
• added: withModes() — scoped enable/restore of terminal modes (raw, alternate screen, mouse, kitty keyboard enhancement, bracketed paste, in-band resize, line wrap, cursor visibility), tracked in TermModes.
• added: probe() detects terminal capabilities and returns a TermInfo.
• added: enableResizeEvents() / disableResizeEvents() — in-band resize (mode 2048) with a SIGWINCH fallback that synthesizes WindowResizeEvent on terminals without the mode.
• added: KeyBinding<A> — declarative key-spec → action mapping ('ctrl+a', aliases); handles kitty repeat events.
• added: color scheme support — queryColorScheme(), enableColorPaletteUpdates() / disableColorPaletteUpdates(); the terminal reports via ColorSchemeEvent.
• added: DECRQM status queries queryBracketedPaste() and queryInBandResize().
• added: flush() — push pending output without close or exit.
• changed: readline gained emacs-style motions — end of line (ctrl+e), word left/right (alt+b/alt+f), delete word (alt+d, alt+backspace, ctrl+w), transpose (ctrl+t), yank (ctrl+y), clear screen (ctrl+l).
• changed: the noColor profile keeps text attributes (bold, reverse, underline, …) and drops only colors, per no-color.org.
• fixed: color downsampling accuracy — RGB→256 quantizes to the nearest color-cube level and considers the grayscale ramp; nearest-color matching runs in OKLab, so desaturated colors no longer land on the wrong hue.

0.5.0

• breaking change
  • changed how reset styles works. Now need explicit reset.
  • refactored Color class, updated examples, tests, etc.
  • export from color_util only what is needed, try to minimize public API surface.
  • readline: changed how to handle escape key (now returns null instead of throwing)
• updated: removed unused methods from FFI interface
• added: query functions for 2027 (Unicode Core)
• added: implements disable individual styles (bold off, italic off, etc)
• added: expose events controllers directly

0.4.0

• updated: updated test cases/coverage
• updated: keyboard handling
• updated: export Style profile
• updated: rgb distance function
• new: added underline styles
• new: example to check luminance (dart/light)

0.3.0

0.2.1
