    longDescription = ''
      The Elixir Language Server provides a server that runs in the background, providing IDEs, editors, and other tools with information about Elixir Mix projects.
      It adheres to the Language Server Protocol, a standard for frontend-independent IDE support.
      Debugger integration is accomplished through the similar VS Code Debug Protocol.
