README

This project contains examples of using Haskell's conduit library.

What is this repository for?

  • These code examples provide iterative examples of building up different uses of conduit (mostly) one step at a time
  • Version 0.1

How do I get set up?

Prerequisites:

  • Have GHC version >= 7.8 installed (examples tested against 7.8.3)
  • Have Cabal version >= 1.20 installed (examples tested against 1.20.0.2)
  • Tested on Windows 8.1 and Amazon Linux AMI
  • telnet or an equivalent tool must be available on the system (for running the examples)

Installing:

  • Run cabal sandbox init first
  • Run cabal configure; install any missing libraries with cabal install library-name
  • Run cabal build
  • Everything should just work from here, assuming your environment is not too crazy/different from the test environments listed above
  • On *nix, you might not see output on the network examples until you Ctrl+C the server

How do I run the examples?

conduit-101-01:

  • Just run the binary built by cabal build; this should be at dist/build/conduit-101-01/conduit-101-01
  • The user prompts should take you the rest of the way

conduit-101-02:

  • Run the binary built by cabal build; this should be at dist/build/conduit-101-02/conduit-101-02
  • From another shell terminal, run telnet 127.0.0.1 4000 (or an equivalent tool to communicate to localhost on port 4000)
  • Type some words; the server output should split each word to a new line until a newline character is read

conduit-101-03:

  • Run the binary built by cabal build; this should be at dist/build/conduit-101-03/conduit-101-03
  • Run the server binary from conduit-101-02
  • Press ENTER for the program to immediately write some output to the server

conduit-101-04:

  • Run the binary built by cabal build; this should be at dist/build/conduit-101-04/conduit-101-04
  • Run the server binary from conduit-101-02
  • Press ENTER to continue to the next setup step
  • From another shell terminal, run telnet 127.0.0.1 4002 (or an equivalent tool to communicate to localhost on port 4002)
  • Press ENTER to move to the "execution" step
  • Now, type some text into the telnet terminal; you should see the same output run through this server as well as the conduit-101-02 server
