SmaCC (Smalltalk Compiler-Compiler) is a freely available parser generator for Smalltalk.Use this package if you want to develop a new parser/scanner/compiler. It is a replacement for the T-Gen parser generator. T-Gen has several limitationsthat make it difficult to produce parsers. SmaCC overcomes T-Gen's limitations.For example, SmaCC can generate parsers for ambiguous grammars and grammarswith overlapping tokens. Both of these are not possible using T-Gen.In addition to handling more grammars than T-Gen, SmaCC has a smaller runtimethan T-Gen and is faster than T-Gen.
