This is a Tree-sitter grammar for Obsidian DataView query language.
The goal of the project is to make it possible to use DataView inside NeoVim. This is a very ambitious goal and tree-sitter grammar is only a little part of it.
Tree-sitter grammar for DataView will provide:
- syntax highlighting in markdown blocks
- an abstraction layer for parsing, which can be used in JavaScript, TypeScript, Python, C, Go, Rust, etc.
There is also example folder which contains an implementation of a «DataView Playground». I call it playground, becuase I would like to run DataView queries in the browser and see the output, since there is no good way to display query results inside NeoVim.
We are in a deep WIP state. Not much stuff is working. There is a lot to do in terms of compatibility.
Overall, there are 3 main topics:
- compatibility with the DataView DQL
- highlighting
- playground
This is a work-in-progress project. Please see compatibility matrix below.
