Thread: parsing geometric operators

I'm creating my own parser/regex combination for fast and lightweight Postgres queries processing (in a user app). So I wanted to double check some details in PG source, but could not find the geometric operators (http://www.postgresql.org/docs/8.4/static/functions-geometry.html) definition/rules neither in gram.y nor in scan.l.

I could try to define the rules based on documentation... but would it be possible to find how they are defined in the PG source?

Thank you,
Konstantin

Please ignore my question. I found "Op" tokens definition in scan.l!
