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 & Server' from drop-down to launch the extension and attach to both the extension and the server.
  • create a file foo.bar, and type typescript. You should see a validation error.
  • set breakpoints in the server or the client
