Christian Clason aa2c18895b ci(nvim-ts): build nvim against PR lib 
Problem: The nvim-treesitter tests use a prebuilt Neovim, which means
changes to the library are not tested and parser generation is locked at
the ABI Neovim supports.

Solution: Build Neovim against the PR version of the library on Ubuntu
and macOS. On Windows, we still download binaries (because one does not
simply build Neovim on Windows...) so we still can check backward
compatibility.

tree-sitter

DOI discord matrix

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:

  • General enough to parse any programming language
  • Fast enough to parse on every keystroke in a text editor
  • Robust enough to provide useful results even in the presence of syntax errors
  • Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
