To run latest master:

  1. Install a language server for a language of your choice
  2. Verify a matching configuration exists under clients in Preferences: LSP Settings
  3. Open a document supported by this language server.
  4. LSP should report the language server starting in the status bar.

Documentation is available at or in the docs directory


Enable the log_debug setting, restart Sublime and open the console. See the Troubleshooting guide for tips and known limitations.

Have you added multiple folders to your Sublime workspace? LSP may not handle your second folder as expected, see this issue for more details.
