Re: How to Parse raw CQL text?

Yes ideally. I’ve been spending a bit of time in the parser the last week. There’s a lot of internals which are still using old terminology and are pretty damn confusing. I’m doing a little investigation into exposing some of the information while also modernizing it. > On Feb 26, 2018, a

Re: How to Parse raw CQL text?
