// Implements a parser for an extended Backus-Naur form (BNF), producing the
|
|
// binary context-free grammar format specified by llama.h. Supports character
|
|
// ranges, grouping, and repetition operators. As an example, a grammar for
|
|
// arithmetic might look like:
|
|
//
|
|
// root ::= expr
|
|
// expr ::= term ([-+*/] term)*
|
|
// term ::= num | "(" space expr ")" space
|
|
// num ::= [0-9]+ space
|
|
// space ::= [ \t\n]*
