v0.5.4

New

• New parseOrElse and parseOrNull shorthand functions for Grammar
• Case-insensitive parsing of literal and regex tokens with ignoreCase=true parameter
• Case-insensitive grammars with Grammar<T>(ignoreCase = true) (makes all literal and regex tokens case-insensitive)
• Parsing with non-root parser is now possible with g.parse(g.someParser, text) for easier testing and debugging
• High level and combinator to type-safely parse sequences of parses up to Tuple7
• New maybe alias for optional

Breaking

• parser1 and parser2 now returns Parser<Tuple2<T1, T2>> instead of Parser<Pair<T1, T2>>

Deprecations

• Parsing functions that start with parseEntire* are deprecated in favor of shorter parse* functions.
• Unary operators on the ParsingContext are deprecated, because they have a different semantics for the same types compared to Grammar scope. Explicit functions like skip or has should be used instead.
