| # This file is an FMPP (http://fmpp.sourceforge.net/) configuration file to |
| # allow clients to extend Calcite's SQL parser to support application specific |
| # SQL statements, literals or data types. |
| # |
| # Calcite's parser grammar file (Parser.jj) is written in javacc |
| # (https://javacc.org/) with Freemarker (http://freemarker.org/) variables |
| # to allow clients to: |
| # 1. have custom parser implementation class and package name. |
| # 2. insert new parser method implementations written in javacc to parse |
| # custom: |
| # a) SQL statements. |
| # b) literals. |
| # c) data types. |
| # 3. add new keywords to support custom SQL constructs added as part of (2). |
| # 4. add import statements needed by inserted custom parser implementations. |
| # |
| # Parser template file (Parser.jj) along with this file are packaged as |
| # part of the calcite-core-<version>.jar under "codegen" directory. |
