Part of #1164 ## Progress updates 🗞️ Waiting for the review and advice, while thinking how to handle escaped string when `new RegExp(pat)`. ## TODOs - [x] `RegExp(Literal = Body + Flags)#parse()` structure - [x] Base `Reader` impl to handle both unicode(u32) and utf-16(u16) units - [x] Global `Span` and local offset conversion - [x] Design AST shapes - [x] Keep `enum` size small by `Box<'a, T>` - [x] Rework AST shapes - [x] Split body and flags w/ validating literal - [x] Parse `RegExpFlags` - [x] Parse `RegExpBody` = `Pattern` - [x] Parse `Pattern` > `Disjunction` - [x] Parse `Disjunction` > `Alternative` - [x] Parse `Alternative` > `Term` - [x] Parse `Term` > `Assertion` - [x] Parse `BoundaryAssertion` - [x] Parse `LookaroundAssertion` - [x] Parse `Term` > `Quantifier` - [x] Parse `Term` > `Atom` - [x] Parse `Atom` > `PatternCharacter` - [x] Parse `Atom` > `.` - [x] Parse `Atom` > `\AtomEscape` - [x] Parse `\AtomEscape` > `DecimalEscape` - [x] Parse `\AtomEscape` > `CharacterClassEscape` - [x] Parse `CharacterClassEscape` > `\d, \D, \s, \S, \w, \W` - [x] Parse `CharacterClassEscape` > `\p{UnicodePropertyValueExpression}, \P{UnicodePropertyValueExpression}` - [x] Parse `\AtomEscape` > `CharacterEscape` - [x] Parse `CharacterEscape` > `ControlEscape` - [x] Parse `CharacterEscape` > `c AsciiLetter` - [x] Parse `CharacterEscape` > `0` - [x] Parse `CharacterEscape` > `HexEscapeSequence` - [x] Parse `CharacterEscape` > `RegExpUnicodeEscapeSequence` - [x] Parse `CharacterEscape` > `IdentityEscape` - [x] Parse `\AtomEscape` > `kGroupName` - [x] Parse `Atom` > `[CharacterClass]` - [x] Parse `[CharacterClass]` > `ClassContents` > `[~UnicodeSetsMode] NonemptyClassRanges` - [x] Parse `[CharacterClass]` > `ClassContents` > `[+UnicodeSetsMode] ClassSetExpression` - [x] Parse `ClassSetExpression` > `ClassUnion` - [x] Parse `ClassSetExpression` > `ClassIntersection` - [x] Parse `ClassSetExpression` > `ClassSubtraction` - [x] Parse `ClassSetExpression` > `ClassSetOperand` - [x] Parse `ClassSetExpression` > `ClassSetRange` - [x] Parse `ClassSetExpression` > `ClassSetCharacter` - [x] Parse `Atom` > `(GroupSpecifier)` - [x] Parse `Atom` > `(?:Disjunction)` - [x] Annex B - [x] Parse `QuantifiableAssertion` - [x] Parse `ExtendedAtom` - [x] Parse `ExtendedAtom` > `\ [lookahead = c]` - [x] Parse `ExtendedAtom` > `InvalidBracedQuantifier` - [x] Parse `ExtendedAtom` > `ExtendedPatternCharacter` - [x] Parse `ExtendedAtom` > `\AtomEscape` > `CharacterEscape` > `LegacyOctalEscapeSequence` - [x] Early errors - [x] Pattern :: Disjunction(1/2) - [x] Pattern :: Disjunction(2/2) - [x] QuantifierPrefix :: { DecimalDigits , DecimalDigits } - [x] ExtendedAtom :: InvalidBracedQuantifier (Annex B) - [x] AtomEscape :: k GroupName - [x] AtomEscape :: DecimalEscape - [x] NonemptyClassRanges :: ClassAtom - ClassAtom ClassContents(1/2) - [x] NonemptyClassRanges :: ClassAtom - ClassAtom ClassContents(2/2) - [x] NonemptyClassRanges :: ClassAtom - ClassAtom ClassContents(Annex B) - [x] NonemptyClassRangesNoDash :: ClassAtomNoDash - ClassAtom ClassContents(1/2) - [x] NonemptyClassRangesNoDash :: ClassAtomNoDash - ClassAtom ClassContents(2/2) - [x] NonemptyClassRangesNoDash :: ClassAtomNoDash - ClassAtom ClassContents(Annex B) - [x] RegExpIdentifierStart :: \ RegExpUnicodeEscapeSequence - [x] RegExpIdentifierStart :: UnicodeLeadSurrogate UnicodeTrailSurrogate - [x] RegExpIdentifierPart :: \ RegExpUnicodeEscapeSequence - [x] RegExpIdentifierPart :: UnicodeLeadSurrogate UnicodeTrailSurrogate - [x] UnicodePropertyValueExpression :: UnicodePropertyName = UnicodePropertyValue(1/2) - [x] UnicodePropertyValueExpression :: UnicodePropertyName = UnicodePropertyValue(2/2) - [x] UnicodePropertyValueExpression :: LoneUnicodePropertyNameOrValue(1/2) - [x] UnicodePropertyValueExpression :: LoneUnicodePropertyNameOrValue(2/2) - [x] CharacterClassEscape :: P{ UnicodePropertyValueExpression } - [x] CharacterClass :: [^ ClassContents ] - [x] NestedClass :: [^ ClassContents ] - [x] ClassSetRange :: ClassSetCharacter - ClassSetCharacter - [x] Add `Span` to `Err(OxcDiagnostic::error())` calls - [x] Perf improvement - [x] `Reader#peek()` should avoid `iter.next()` equivalent - [x] ~~Use `char` everywhere and split and push 2 surrogates(pair) for `Character`?~~ - [x] ~~Try 1(+1) loop parsing for capturing groups?~~ ## Follow up - [x] @Boshen Test suite > #4242 - [x] Investigate CI errors... - Next... - Support ES2025 Duplicate named capturing groups? - Support ES20XX Stage3 Modifiers? |
