LLgen - an ELL(1) parser generator


LLgen is a tool for generating an efficient recursive descent parser from an ELL(1) grammar. The grammar may be ambiguous or more general than ELL(1): there are both static and dynamic facilities to resolve the ambiguities. LLgen is described in the following papers:
