[back to package description]

Z-IO

Linux Build Status MacOS Build Status Windows Build Status

This package provides basic IO operations:

  • IO resource management, resource pool
  • File system
  • Network: DNS, TCP, UDP and IPC
  • Buffered input and output
  • High performance logger
  • High performance timer

Requirements

  • A working haskell compiler system, GHC(>=8.6), cabal-install(>=2.4), hsc2hs.

  • Tests need hspec-discover.

Example usage

> :set -XOverloadedStrings  
> import Z.IO.Network
> import Z.IO.Resource
> import Z.IO.Buffered
> 
> -- call getAddrInfo to perform DNS
> head <$> getAddrInfo Nothing "www.bing.com" "http"
AddrInfo {addrFlags = [AI_ADDRCONFIG,AI_V4MAPPED], addrFamily = SocketFamily 2, addrSocketType = SocketType 1, addrProtocol = ProtocolNumber 6, addrAddress = 204.79.197.200:80, addrCanonName = }
>
> import qualified Z.Data.Text as T
> -- send a simple HTTP request
> :{
let addr = SocketAddrInet 80 (tupleToInetAddr (13,107,21,200))
-- addr = ipv4 "13.107.21.200" 80
in withResource (initTCPClient defaultTCPClientConfig{ tcpRemoteAddr = addr}) $ \ tcp -> do
    i <- newBufferedInput tcp 
    o <- newBufferedOutput tcp
    writeBuffer o "GET http://www.bing.com HTTP/1.1\r\nHost: www.bing.com\r\n\r\n"
    flushBuffer o
    readBuffer i >>= pure . T.validate
:}
"HTTP/1.1 200 OK\r\nDate: Sat, 19 Sep 2020 06:11:08 GMT\r\nContent-Length: 0\r\n\r\n"
>
> -- Start a TCP echo server, use @nc -v localhost 8080@ to test
> :{
startTCPServer defaultTCPServerConfig{ 
    tcpListenAddr = SocketAddrInet 8080 inetLoopback} $ \ tcp -> do
        i <- newBufferedInput tcp 
        o <- newBufferedOutput tcp
        forever $ readBuffer i >>= writeBuffer o >> flushBuffer o
}
