Nimsuggest replying with garbage value through socket every second invocation - then the channel breaks

[ghost]

Hello!

I made a nim extension for my code editor 2 years ago and I had a lot of problem with trying to work around nimsuggest's output. Now only the first invocation succeeds(testing this with def $file:$L:$C over and over) and for the second invocation I just get empty lines then the socket channel just breaks. Is this expected behavior? And is there any way to make nimsuggest use a standardized response format like json or xml?

This is not documented properly but nimsuggest process one query per socket.
