In a previous posts we examined the current state of GUI programming in Haskell, how imperative libraries get in the way of functional beauty, and how (non-FRP) reactive programming enables short, declarative code and facilitates code reuse. …
As discussed in a previous post, purely functional GUI frameworks may fail to deliver in terms of feature coverage, look-and-feel and codebase scalability. As a result, many programmers turn back to good-old Gtk+ for their user interfaces …
GUI programming in functional and logic languages tends to feel quite hard. There is nothing intrinsic in FP that makes GUI programming extra hard, but when everywhere else you are surrounded by nice, abstract, compositional, high-level descriptive definitions, working at …
While code written in Haskell is very declarative and mathematical, as soon as we try to create a user interface, we’ll be slapped on the cheek by a wave of IO that will turn our code procedural in no time. …
Some time ago I tried to create big programs with user interfaces in Haskell and found that none of the FRP frameworks worked as expected. Some were incomplete, others didn’t compile, and efficiency was an issue in those that did …
Can we show how powerful Haskell is with an application that is very useful and, at the same time, surprisingly simple?
I present Keera Posture: a program that will warn you when you sit or stand in a straining …
