I’ve been practicing my F# recently – I took a gap for a little bit, and just got back into it. I’ve been working through my ‘Foundations of F#’ book, and have hit a slight snag.
There is one line of code I can’t get to compile, I get the ‘Missing format specifier.’ error for the following line:
let print x = printfn “A%” x
The intellisense highlights under the “A%” bit.. Any ideas?
The hunt continues!
Update – worked it out, it should be “%A” rather than “A%” – looks like a typo!!
Recently a post from one of my ex-colleagues got me interested in working my way through a set of problems at the ‘Project Euler‘ site. He piqued my interest, and I started working my way through them (not at any great speed mind – I’ve only done 4 so far – and I’ve been doing it for 3 days!!).
Then he posted another post about the problems and solving them in a functional way rather than errr…. non-functional – thanks Steve! Now I feel compelled to look into the functional world, and with good reason from a .net development point of view.
F# is the Microsoft Research functional language, and is designed to fit in nicely with the .NET framework, and (indeed) Visual Studio. To be honest, I haven’t explored much beyond looking at the examples and playing with them – but it looks good. In line with what Steve (hackinghat.com) said, I too haven’t really played with functional programming since uni, though in my case, that’s only 4-5 years ago now :)
