Just a FYI since I didn't find any other methods of messaging.
I committed an update to lsp-mode for Emacs that sets up a connection to your server so you only need to include the lsp-mode package, specify the server path and add a hook when starting vhdl-mode. For example:
(setq lsp-vhdl-server-path "/PATH/TO/vhdl-tool")
(add-hook 'vhdl-mode-hook 'lsp))
Thanks! I wanted to do something like that but Emacs was a bit mysterious...
I'll update the Emacs instructions.
I've updated the example Emacs config. Thanks again!
