• Tree-sitter: coder3101/tree-sitter-proto
• Language Servers: protobuf-language-server

<!-- TBD: Clarify which language server(s) to use / Feature support. ## Setup ### Install protobuf-language-server Install protobuf-language-server and make sure it's in your PATH: ``` go install github.com/lasorda/protobuf-language-server@latest which protobuf-language-server ``` ### Install ProtoLS Install protols and make sure it's in your PATH: ``` cargo install protols which protols ``` ## Configuration ```json [settings] "lsp": { "protobuf-language-server": { "binary": { "path": "protols" } } } ``` ## Formatting ProtoLS supports formatting if you have `clang-format` installed. ```sh # MacOS: brew install clang-format # Ubuntu sudo apt-get install clang-format # Fedora sudo dnf install clang-tools-extra ``` To customize your formatting preferences, create a `.clang-format` file, e.g.: ```clang-format IndentWidth: 4 ColumnLimit: 120 ``` Or you can have zed directly invoke `clang-format` by specifying it as a [formatter](https://zed.dev/docs/reference/all-settings#formatter) in your settings: ```json [settings] "languages": { "Proto": { "format_on_save": "on", "tab_size": 4, "formatter": { "external": { "command": "clang-format", "arguments": ["-style={IndentWidth: 4, ColumnLimit: 0}"] } } }, } ``` -->
