Scripting in Haskell

Writing scripts in Haskell using Stack is straight-forward and reliable. We've made a screencast to demonstrate this:

Summary

Slides in the screencast cover:

• What Haskell is
• What Stack is
• We make a case for reproducible scripting

We cover the following example cases:

• Hello, World! as a Haskell script
• Generating a histogram of lines of a file
• Using FSNotify to watch a directory for any changes to files

In summary, we show:

1. Scripting in Haskell is reproducible: it works over time without bitrot.
2. It's easy to do, just add a shebang #!/usr/bin/env stack to the top of your file.
3. We can use useful, practical libraries that are not available in traditional scripting languages.
4. Our script is cross-platform: it'll work on OS X, Linux or Windows.
