Note

If you plan to use a symbolic link to point to the language server, you will want to instead use a wrapper script like the one below. This is required because the language server expects to find files in the current working directory.

bash 
#!/bin/bash
exec "<path-to-directory>/bin/lua-language-server" "$@"
