termparser 0.5.0

ANSI Terminal escape sequence parser for terminal applications.

0.5.0

• breaking: toSpec() folds shift into the produced character for char-kind keys ('A', '!'); named keys keep explicit modifiers; new KeyCode.shiftProduced flag marks kitty alternate shifted keys
• breaking: CapsLock/NumLock state bits (64/128) no longer reported as held modifiers (bit 128 was mislabeled keyPad); lock state is parsed and dropped
• breaking: parser functions return Event?; the NoneEvent sentinel is gone, fixing its leak to the public queue on unhandled CSI finals
• added: KeyEvent.text — the kitty CSI-u typed-text parameter, on presses and repeats, never on releases
• added: ColorSchemeEvent to report terminal color scheme (CSI 997)
• added: InBandResizeEvent to report terminal resize in band (CSI 2048)
• added: parser for DA2 (secondary device attributes)
• added: query and probe support for bracketed paste
• changed: color query events keep the query and index flags
• added: DEC ANSI conformance suite against the vt100.net state machine, with a reasoned deviations registry (specs/dec_ansi/)
• added: fuzz test suite (stream / structured / utf8 harnesses) with seed corpus, crash dump + replay regression guard, and naive shrinker (see specs/FUZZ_PLAN.md)
• fixed: SGR mouse motion with a button held now reports drag instead of moved (drags were undetectable; MouseButtonAction.drag was unreachable)
• fixed: malformed CSI sequences are consumed to the final byte instead of replaying their remainder as input (a phantom-keypress injection vector)
• fixed: OSC string bytes 0x20-0x2E accumulated instead of dropped
• fixed: DCS header params accumulated; hook passthrough at 0x40-0x7E
• fixed: CAN/SUB cancel the in-flight sequence and deliver the control byte
• fixed: SOS/PM/APC strings are swallowed instead of replaying their bodies as input
• fixed: FormatException on malformed UTF-8 (allowMalformed in utf8 decoder)
• fixed: FormatException on non-numeric CSI params (int.tryParse in csi/key parsers)
• fixed: base64Decode crash on malformed OSC 52 clipboard payload
• fixed: _inTextBlock leak past DCS termination causing RangeError on later paste close
• fixed: RangeError on UTF-8 BOM (empty decode forwarded to ctrlOrKey)
• added: @visibleForTesting getters on Engine (sequenceByteCount, paramCount, inTextBlock)

0.4.0

• fixed: event filter for eventTransformer
• added: helper functions to check for single key modifiers
• added: parser support for CSI 2027 Unicode Core
• added: debug capability to be more easy to trace parsing issues
• refactor: simplify provider parser with an eventQueue
• refactor: content blocks handle to unify for example bracketed paste and text content (terminal version)

0.3.0

• added: QueryTerminalWindowSizeEvent to return window size event
• added: ClipboardCopyEvent to return clipboard content

0.2.0

• fixed: fixed OSC10 parsing

0.1.1
