10015 :: Sending Directory Listing over Sockets Help.

  I am trying to send a directory listing over sockets but getting an error. Please help.

  Example remote string being sent: The keyword, "directory" is cut out and only the directory path is fed into the userInput variable. The intent is to have the directory listing of both directories and files saved and sent back to the requestor.

  Example string being sent: directoryc:usersnatedesktop

  
  var input = socket.recvLine()
  if input[0..8] == "directory":
                  let userInput = input[9..^1]
                  let filePaths = toSeq(walkDir(userInput, relative = true))
                    .mapIt(it.path)
                  socket.send(filePaths)
  
  
  
  Error:
  
  Error: type mismatch: got <Socket, seq[string]>
  but expected one of:
  proc send(socket: Socket; data: pointer; size: int): int
    first type mismatch at position: 2
    required type for data: pointer
    but expression 'filePaths' is of type: seq[string]
  proc send(socket: Socket; data: string; flags = {SafeDisconn})
    first type mismatch at position: 2
    required type for data: string
    but expression 'filePaths' is of type: seq[string]
  
  expression: send(socket, filePaths)
  
  Run

  Not to appear rude, but I suggest you to read https://nim-lang.org/docs/tut1.html, https://nim-lang.org/docs/tut2.html and https://narimiran.github.io/nim-basics/ before writing actual Nim code. The error you're getting is because socket.send expects a string, but you're passing it a sequence of strings. You actually need to convert the sequence into the desired format - e.g. comma separated, or some other way. For this you can use https://nim-lang.org/docs/strutils.html#join%2CopenArray%5Bstring%5D%2Cstring

  Hey, got it working. Thanks for making me think better....lol.

  Here is what I was able to come up. Not the prettiest but its working.

  
  if input[0..3] == "path":
                  var my_path = input[5..^1]
                  for entry in walkDir(my_path):
                      let the_path = entry.path
                      let path_to_send = $the_path
                      socket.send(path_to_send & "\n")
  
  output:
  
  path c:\users
  c:\users\All Users
  c:\users\Default
  c:\users\Default User
  c:\users\desktop.ini
  c:\users\nater
  c:\users\Public
  Run

  Thanks again!
