dumbql

I coincidentally worked on something similar but I kept closer to the SQL standard. It grew out of business cases where you don't have strongly typed data to act on. I more or less adopted the syntax from dumbql (https://github.com/tomakado/dumbql) and started off with a peg parser using ohm.js. As I started benchmarking I realized how slow it was and started looking for "fast paths" using regex. I ultimately resorted to a recursive descent parser similar to Elo. At that stage I already had a lot of tests and api in place, so I was able to get a lot of help from Claude. Website here: https://filtron.dev

Hi everyone! I'd like to share a Go library I've been working on over the past month. It's a simple query (or more specifically, filtering) language inspired by KQL (Kibana's query language) and GitHub's search syntax. It started as a project for a YouTube screencast about building small languages from scratch. However, I enjoyed the process so much that I decided to keep developing it beyond the scope of the video. Key highlights: - Field, boolean, one-of expressions - Schema validation - Easy integration with github.com/Masterminds/squirrel or directly with SQL drivers - Struct matching: reflection-based (slower, but works immediately) or via code generation (faster) I still have plenty of enhancements planned (tracked in the project's issues), but DumbQL is already quite usable. Feedback and contributions are very welcome!
