The Polar Game in Haskell, Day 5 3/4: a Bug Fix and liftM

from blog Praise, Curse, and Recurse, | ↗ original
Jeff Licquia has been playing further with the code and so have I. He discovered a bug in the version I posted in yesterday's installment (my bad). In slide' I neglected to call slide' in the recursive version of slide' but called the existing non-monadic slide. In other words, I had: slide' ( t : Empty : ts ) = noscore ( Empty : ( slide ( t : ts...

Arduino, Day 2: the Most Minimal Scripting Language, or, Reifying Frozen Functions for Fun
21 Aug 2013 | original ↗

Planet Haskell readers might want to skip this one. Recently I've been thinking about the possibilities offered by embedded interpreters. This is becoming a common design pattern in commercial software -- games written in C++ embedding Lua, for example, or Python for graphical user interfaces, or occasionally Scheme, or even the JVM. However,...

Arduino, Day 1
14 Aug 2013 | original ↗

Warning for Planet Haskell readers: imperative content! (Or, I tried to get GHC working in 2048 bytes of RAM but didn't get very far...) A friend of mine sent me a RedBoard and asked me to collaborate with him on a development idea. So I'm playing with an Arduino-compatible device for the first time. I've been aware of the Arduino devices, and...

So, trying wxHaskell. First, I want to try removing everything that might be left over from yesterday's experiments: Pauls-Mac-Pro:~ paul$ brew list gettext libffi pkg-config xz Pauls-Mac-Pro:~ paul$ brew uninstall gettext libffi pkg-config xz Uninstalling /usr/local/Cellar/gettext/0.18.3...

The Polar Game in Haskell, Day 6/12: Towards a GUI, Continued
16 Jul 2013 | original ↗

OK, so when I left off last time, I was running into a gruesome link error. I found this Stack Overflow thread and the first accepted answer fixed the problem. However, it seems that the answer may be to avoid MacPorts versions of the libraries I need. So I'm going to attempt to clean that all out and use Homebrew. So, first: sudo port -fp...

The Polar Game in Haskell, Day 6: Towards a GUI
16 Jul 2013 | original ↗

So, I have some time today to program and I want to see how far I can get in starting to develop a GUI for my game, incomplete as it is. Can I get a window displayed and reacting to mouse or keyboard events, and drive the game logic with it? I came across the paper FranTk -- A Declarative GUI Language for Haskell (PDF file link) by Meurig Sage...
