Hi, I'm Rene Saarsoo 👋

I'm the autor of several somewhat-popular open source libraries: SQL Formatter, Lebab, JSDuck.

Currently I'm mainly working on an SQL Parser CST library that produces a Concrete Syntax Tree (rather than the usual Abstract one). Sometimes I even blog about this.

There seems to be a bit of a theme with these libraries: they all revolve around static analysis of source code. I guess that's my passion.

🚲 My other passion is riding stupid-long distances on a road bike. I guess that's also a theme - I like doing hard stuff.

🔭 It happens that I'm also looking for a job. Feel free to send me an e-mail me if you have a project that's at least as hard as writing an SQL parser.

Add support for custom quote types

Similarly to how variable types can be specified with a regex string, a string (and identifier) can now also be specified the same way. Fixes #503
