SQL parser lexical analyzer: input file for the GNU Flex lexer generator
(c) 1997 Innobase Oy
Created 12/14/1997 Heikki Tuuri
Published under the GPL version 2
The InnoDB parser is frozen because MySQL takes care of SQL parsing.
Therefore we normally keep the InnoDB parser C files as they are, and do
not automatically generate them from pars0grm.y and pars0lex.l.
How to make the InnoDB parser and lexer C files:
1. Run ./make_flex.sh to generate lexer files.
2. Run ./make_bison.sh to generate parser files.
These instructions seem to work at least with bison-1.875d and flex-2.5.31 on
Linux.
