# gotlin-lsp

Minimal stdio language server for `.gt` files.

Current support:

- `initialize`
- `shutdown`
- `exit`
- `textDocument/didOpen`
- `textDocument/didChange`
- `textDocument/didClose`
- publish diagnostics from the existing Gotlin parser/code generator
- `textDocument/hover` for packages, imports, and top-level functions
- `textDocument/definition` for imported namespaces and top-level functions
- simple semantic diagnostics for duplicate imports/functions and undefined names
- optional fallback to `gopls` for hover/definition on Go-imported symbols

Build:

```bash
go build -o ./bin/gotlin-lsp ./cmd/gotlin-lsp
```

Use your editor's custom LSP configuration to launch:

```bash
./bin/gotlin-lsp
```

## gopls bridge

If `gopls` is installed, `gotlin-lsp` will try to use it as a fallback for hover and definition on Go-imported symbols.

You can set an explicit path with:

```bash
GOTLIN_GOPLS_PATH=/absolute/path/to/gopls ./bin/gotlin-lsp
```
