Hey, all. I'm trying to interface with nimsuggest according to the the [Nim IDE
Integration Guide](https://nim-lang.org/docs/nimsuggest.html) and have run into
some issues with sockets. I'm trying to connect to nimsuggest over port 6000
but my connection keeps being refused. Any help would be greatly appreciated!

EndToken = "\e"
PauseToken = "\e\e"
ClearToken = "\e\e\e"
Port = Port 6000

results: Channel[string]
commands.open()
results.open()
proc processTask(task: string) =
let socket = newSocket()
for i in 0..9:
socket.connect("localhost", Port) # Connection refused [OSError]
socket.send(&"{task}\c\l")
discard "do stuff here..."
socket.close()
results.send(EndToken)
proc suggestThread() {.thread.} =
while true:
let cmd = commands.recv()
case cmd
of EndToken: break
of PauseToken: os.sleep(300)
else: processTask(cmd)
var prevProject: string
var nimsuggest: Process
proc shutdown() {.noconv.} =

nimsuggest.terminate()
nimsuggest.close()
nimsuggest = nil

let pathToExe = Path findExe("nimsuggest")
assert pathToExe.string.len != 0
