Hi

today I found an article about preparing a new parser for duckdb.

I remember here was a discussion about it, so this can be an idea on how to do it.

https://duckdb.org/2024/11/22/runtime-extensible-parsers

I've been working on Lime https://codeberg.org/gregburd/lime and a replacement of flex and bison in Postgres using Lime https://github.com/gburd/postgres/tree/lime which isn't yet stable or ready but the intention is/was to use a new parser that has the ability to be extended (changed) at runtime so that our extension authors can do some more interesting tricks.

Not a finished branch, but something to talk about for sure.

Pavel

best.
