Learning Real Haskell Incrementally
October 24, 2015
The audience laughs appreciatively as Mark Fine talks about the standard books used by new Haskellers: LYAH, Real World Haskell, etc. Oftentimes these books contain code that no longer compiles, or reference obsolete libraries. Mark suggests another way to learn: pick small but real projects, and iterate on them.
In this video he shares tricks to keep the compiler happy and to get yourself unstuck while developing Haskell projects.
- It’s difficult getting your first real thing done in Haskell
- Some background about Mark’s involvement at Swift Navigation
- Things you have probably already tried
- The big stack o’ Haskell books only gets you so far
- Github code search for examples
- Stack Overflow
- Approaches to working and learning incrementally
- Coding “wishfully” is a powerful way to learn Haskell
- Growing programs forward from inputs as well as backwards from outputs
- Make minimum viable changes to keep compiler happy
- Compile early often and always!
- One great tool is punting on a function definition with
- Real example of working iteratively
- It’s a project in twelve steps
- Tries to answer which NFL teams are best
- Notice this project is a problem that Mark enjoys, hence easier to stick with
