+# tree-sitter-rune
+
+[Rune](https://rune-rs.github.io/) grammar for [tree-sitter](https://tree-sitter.github.io/).
+
+Provides syntax highlighting, indentation, code folding, and scope tracking for `.rn` files.
+
+## Supported Syntax
+
+- Functions (`fn`, `pub fn`, `async fn`)
+- Structs (named, tuple, unit)
+- Enums (unit, tuple, struct variants)
+- Modules and imports (`mod`, `use`)
+- Control flow (`if`/`else`, `match` with guards, `loop`, `while`, `for`)
+- Pattern matching (tuple, struct, enum, or-patterns, wildcards, rest)
+- Closures (sync and async)
+- Template literals (`` `hello ${name}` ``)
+- Object literals (`#{ key: value }`)
+- Generators (`yield`)
+- Async/await and `select` blocks
+- `is` / `is not` type checking
+- Macro invocations (`println!()`)
+
+## Installation
+
+### Neovim (nvim-treesitter)
+
+Add a custom parser in your Neovim config:
+
+```lua
+local parser_config = require("nvim-treesitter.parsers").get_parser_configs()
+parser_config.rune = {
+  install_info = {
+    url = "https://github.com/TODO/tree-sitter-rune",
+    files = { "src/parser.c", "src/scanner.c" },
+    branch = "main",
+  },
+  filetype = "rune",
+}
+
+vim.filetype.add({
+  extension = {
+    rn = "rune",
+  },
+})
+```
+
+Then run `:TSInstall rune`.
+
+### Formatter Integration
+
+Rune ships a built-in formatter (`rune fmt`) since v0.13. To integrate with [conform.nvim](https://github.com/stevearc/conform.nvim):
+
+```lua
+require("conform").setup({
+  formatters_by_ft = {
+    rune = { "rune_fmt" },
+  },
+  formatters = {
+    rune_fmt = {
+      command = "rune",
+      args = { "fmt", "$FILENAME" },
+      stdin = false,
+    },
+  },
+})
+```
+
+## Development
+
+### Prerequisites
+
+- [Node.js](https://nodejs.org/) (v18+)
+- [tree-sitter CLI](https://tree-sitter.github.io/) (`cargo install tree-sitter-cli` or `npm i -g tree-sitter-cli`)
+- C compiler
+
+### Build
+
+```bash
+npm install
+npx tree-sitter generate
+```
+
+### Test
+
+```bash
+npx tree-sitter test
+```
+
+### Parse a file
+
+```bash
+npx tree-sitter parse path/to/file.rn
+```
+
+### Preview highlighting
+
+```bash
+npx tree-sitter highlight path/to/file.rn
+```
+
+## Query Files
+
+| File | Purpose |
+|---|---|
+| `queries/highlights.scm` | Syntax highlighting |
+| `queries/indents.scm` | Auto-indentation |
+| `queries/folds.scm` | Code folding |
+| `queries/locals.scm` | Scope/variable tracking |
+| `queries/tags.scm` | Code navigation (definitions, references) |
