Tradition has it that when a new programming language is introduced,
new scanner and parser generators are written in that language, and
generate code for that language. Traditional also has it that the
new tools are modeled after the old lex and yacc tools, both in terms
of the algorithms used, and often the syntax as well. The language
Standard ML is no exception: ml-lex and ml-yacc are the SML
incarnations of the old Unix tools.
.
This package has two new tools, ml-ulex and ml-antlr, that follow
tradition in separating scanning from parsing, but break from
tradition in their implementation: ml-ulex is based on regular
expression derivatives rather than subset-construction, and ml-antlr
is based on LL(k) parsing rather than LALR(1) parsing.
