this will be a tree-sitter implementation for nix-shell files.

try one of the following:

• nix build => build the parser
• nix develop => manually/interactively generate the parser
  • tree-sitter generate

non-flake equivalents:

• nix-build
• nix-shell

development workflow

guide on using tree-sitter: https://tree-sitter.github.io/tree-sitter/creating-parsers

roughly:

1. nix develop
2. tree-sitter generate
3. tree-sitter test

run nix run '.#clean' before committing to avoid checking in build artifacts.

the parser is defined in grammar.js, and tests live in corpus/.
