    YACC\/Bison generate table driven parsers, which means the “processing logic” is contained in the parser program’s data, not so much in the parser’s code. The pay off is that even a parser for a very complex language has a relatively small code footprint. <\/p>\n

    ANTLR generates recursive descent parsers, which means the “processing logic” is contained in the parser’s code, as each production rule of the grammar is represented by a function in the parser’s code. The pay off is that it is easier to understand what the parser is doing by reading its code. Also, recursive descent parsers are typically faster than table driven ones. <\/p><\/div>\n<\/p><\/div>\n<\/li>\n
