Functional approaches to dependency injection | F# for fun and profit
Part one of a series, starting with partial application. This post is part of the F# Advent Calendar in English 2016 project. Check out all the other great posts there! And special thanks to Sergey Tihon for organizing this. UPDATE: This post is superceded by a newer one here. For people who are learning functional programming techniques, one of the more common questions is: â€œhow do you do depende

What's new in purely functional data structures since Okasaki?
Since Chris Okasaki's 1998 book "Purely functional data structures", I haven't seen too many new exciting purely functional data structures appear; I can name just a few: IntMap (also invented by Okasaki in 1998, but not present in that book) Finger trees (and their generalization over monoids) There are also some interesting ways of implementing already known datastructures, such as using "nested

Translating Haskell to C++ metaprogramming
Haskell and C++ are very different programming languages. Haskell is purely functional and C++ is imperative. While â€˜normalâ€™ C++ is imperative, C++ metaprogramming is purely functional, just like Haskell. This blog shows examples of Haskell code that Iâ€™ve translated to C++. Why would you do this? Last week I blogged about Blasien. Blasien is a set of header files for writing literal validated XML
