Networking

Pyr has built-in TCP networking via std/net.

 
imp std/net { listen, connect }
imp std/io { println }

A simple echo server that handles one connection.

 
fn echo_server() {
  server = listen("127.0.0.1", 9000)
  defer net.close(server)

  conn = server.accept()
  defer net.close(conn)

  data = conn.read()
  conn.write(data)
}

Connect to a server, send data, read response.

 
fn client() {
  conn = connect("127.0.0.1", 9000)
  defer net.close(conn)

  conn.write("hello")
  response = conn.read()
  println(response)
}

fn main() {
  spawn { echo_server() }
  client()
}
