Other Editors

Install a Language Server Protocol client for your tool. Then invoke the language server executable in a client-specific way.

The server can be launched in three modes:

• Stdio (the default mode)
  • The language server uses the standard streams for JSON-RPC communication
• TCP Server
  • The language server starts a server socket and listens on --tcpServerPort
• TCP Client
  • The language server tries to connect to --tcpClientHost and --tcpClientPort

The mode is automatically determined by the arguments provided to the language server.
