Hi, We're utilizing Calcite's parser and need to customize it for a certain dialect. In the past, we've just been keeping a fork of the parser and making changes to the core template file. We wanted to try utilizing some of the hooks that Calcite provides to ease the maintenance burden when modifying the parser.
We've noticed hooks such as this one: https://github.com/apache/calcite/blob/2d0b3acb11169b307dc165c1fae8b7c92b888ae9/core/src/main/codegen/templates/Parser.jj#L326-L333 If we wanted to customize that production to add support for a keyword, how would we go about doing it? We've seen the configuration file for freemarker and have seen how to add new productions for new statements, but we haven't found a way to hook into the methods like these ones for modifying existing statements. Thanks. --Jonathan Sternberg
