The Lemon program is an LALR(1) parser generator. It takes a context free
|
|
grammar and converts it into a subroutine that will parse a file using that
|
|
grammar.
|
|
|
|
Lemon is similar to much more famous programs Yacc and Bison. But lemon is
|
|
not compatible with either of them; there are several important differences:
|
|
|
|
- Lemon using a different grammar syntax which is less prone to
|
|
programming errors
|
|
|
|
- Lemon generates a parser that is faster than Yacc or Bison parsers
|
|
(according to the author)
|
|
|
|
- The parser generated by Lemon is both re-entrant and thread-safe
|
|
|
|
- Lemon includes the concept of a non-terminal destructor, which makes
|
|
it much easier to write a parser that does not leak memory
