|
|
|
|
The Lemon program is an LALR(1) parser generator that takes a
|
|
|
|
|
context-free grammar and converts it into a subroutine that will parse a
|
|
|
|
|
file using that grammar. Lemon is similar to the much more famous
|
|
|
|
|
programs "yacc" and "bison", but is not compatible with either.
