NOTE

The Sprocket Visual Studio Code extension is currently in very early development. You may also experience various issues, such as needing to manually restart the Sprocket extension if it crashes. We plan to improve all of these things as we continue to develop the extension.

🏠 Overview

This extension provides support developing bioinformatics workflows via the <a href="https://openwdl.org/">Workflow Description Language</a>. It does this by leveraging the sprocket command line tool (and the wdl family of crates).

📚 Getting Started

To get started, follow the instructions outlined in the documentation.

🎨 Features

Basic syntax highlighting using a complete and up-to-date TextMate grammar. This grammar is slated to drive GitHub's syntax highlighting for WDL files in a future release.
Document and workspace diagnostics from static analysis courtesy of the language server protocol implementation provided by sprocket analyzer.
Code snippets for common WDL constructs and conventions.

Note: more features will be added as sprocket is developed. Please check out the activity on the Sprocket repository to see what we're working on next!

Configuration

The extension provides the following configuration options:

sprocket.server.checkForUpdates: Whether to check for updates to the automatically installed sprocket tool when the extension starts.
sprocket.server.path: The path to the sprocket command line tool. Use this to specify a custom installation of sprocket.
sprocket.server.verbose: Configures the verbosity of sprocket output. Valid values are Verbose, Information, and Quiet; defaults to Quiet.
sprocket.server.lint: Passes the --lint flag to sprocket; this enables additional linting checks that are not enabled by default.

Known Issues

The extension is in an early stage of development and may not work as expected.
When sprocket unexpectedly terminates, the extension does not automatically restart it and you must manually restart the extension host to recover from the error; this will change in the future as the extension becomes more stable.
A number of popular LSP features, such as "Go To Definition", are not yet implemented.

Development

Setup

To build the extension, Node.js, npm, and yarn must be installed.

To install Node.js, follow these instructions.

To install yarn, run the following command:

npm install -g yarn

Finally, install the project dependencies by running the following command:

yarn install

Ensure the Yarn binaries directory is on your path by adding the following to your shell profile:

export PATH="$(yarn global bin):$PATH"

Building

To build the extension, run the following command:

yarn compile

This command will automatically be run when you start the extension in the development environment or when packaging the extension.

Running The Development Extension

To run the extension, open this directory in VS Code and press F5.

This will open a new VS Code window with the extension automatically loaded.

Installing The Extension

To install the extension, you can package it as a .vsix file and install it.

To package the extension, install the vsce tool:

yarn global add @vscode/vsce

Then package the extension by running:

vsce package --yarn

This will generate a sprocket-vscode-<version>.vsix file that you can install in VS Code using the Extensions: install from VSIX command.
