CM-Lex and CM-Yacc
A lexer and parser generator for Standard ML and Haskell
Existing lexer and parser generators such as Lex and Yacc suffer from
practical inconveniences because they use disembodied code to
implement actions. To prevent this problem, CM-Lex and CM-Yacc
generate closed functors that are then instantiated by the programmer
with appropriate action code. This results in all code being type
checked in its appropriate context, and it assists the type checker in
localizing errors correctly.
CM-Lex and CM-Yacc are implemented for both Standard ML and Haskell.
However, both versions are implemented in Standard ML. Installation
instructions appear in the INSTALL file.
