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