README

This is the README for the "languageprovider-sample"

---

This folder contains a sample VS code extension that demonstrates an extension that runs a language server

The extension observes all 'plaintext' documents (documents from all editors not associated with a language) and uses the server to provide validation and completion proposals.

The code for the extension is in the 'client' folder. It uses the 'vscode-languageclient' node module to launch the language server.

The language server is located in the 'server' folder.

How to run locally

• npm install to initialize the extension and the server
• npm run compile to compile the extension and the server
• open this folder in VS Code. In the Debug viewlet, run 'Launch Client' from drop-down to launch the extension and attach to the extension.
• create a file test.txt, and type typescript. You should see a validation error.
• to debug the server use the 'Attach to Server' launch config.
• set breakpoints in the client or the server.
