Welcome to the Mini-WDL Language Server Extension! This project is a Visual Studio Code extension designed to enhance developer productivity for Workflow Description Language (WDL) authors. It integrates advanced language features like syntax highlighting, document symbol detection, and more using a Rust-based Language Server Protocol (LSP) implementation.
- Syntax Highlighting: Provides basic syntax highlighting for .wdl files using TextMate grammars.
- Document Symbol Detection: Detects tasks and workflows in .wdl files and displays them in the Outline view.
- Go-to Definition: Navigate to the definition of tasks and workflows.
- Find References: Locate all references to tasks and workflows across documents.
- Semantic Code Highlighting: Highlight WDL constructs semantically.
- Diagnostics: Provide error checking and diagnostics for WDL files.
The Mini-WDL extension is to improve developer tooling for Workflow Description Language (WDL). It aims to provide a seamless development experience for workflow authors by integrating essential language features into VS Code.
- To install the Mini-WDL extension, you will need to install Rust, once rust is installed get on to it😁:
Clone the repository:
git clone https://github.com/<your-username>/mini-wdl-extension.gitNavigate to the project directory:
cd mini-wdl-extensionInstall Node.js dependencies:
npm install- Compile the Rust Language Server:
Navigate to the server directory:
cd serverBuild the Rust server:
cargo build- After building, ensure the binary exists at server/target/debug/mini-wdl-server.
Return to the root directory:
cd ..Build the extension:
npm run compile- Open a .wdl file in VS Code.
- The extension will automatically activate and provide syntax highlighting.
- Use the Outline view (Ctrl+Shift+O) to navigate tasks and workflows.
