[back to package description]

Z-IO

This package is part of Z project, provides basic IO operations:

IO resource management, resource pool
File system operations
Network: DNS, TCP, UDP and IPC
Buffered input and output
Process management
Environment settings
High performance logger
High performance low resolution 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 = 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 = SocketAddrIPv4 ipv4Loopback 8080} $ \ tcp -> do
        i <- newBufferedInput tcp
        o <- newBufferedOutput tcp
