Terrible implementation of nimsuggest integration with zah/nim.vim
" :source this file in your "main" nim file to activate.
" You can run :source again to switch main file or when nimsuggest crashes.
" You can also :call nimsuggest#run('use') to see all uses of the thing your
" cursor is on.
"call system("killall nimsuggest")
let nimsuggest_job = job_start(["nimsuggest", "--stdin", "--v2", "--debug", "--log", expand("%")], {

\ "out_mode" : "nl",
