I started reading the book Programming Erlang and while I read I blog along what I find most interesting/important. In the end, this will hopefully be some kind of erlang tutorial, for your pleasure and my reference. I also started creating an Erlang Cheat Sheet with all the syntax on it. Here are the previous posts and now comes the third:

funs

Funs are anonymous functions. Funs can be assigned to variables and, more importantly, passed as arguments into functions and also be returned by functions - these would be called higher order functions.

Yesterday I started reading the next chapter called “Sequential Programming”. It actually is about functional programming: functions, anonymous functions, higher order functions, predicates, pattern matching for calling functions a.s.o. - I had to read most of it twice to actually understand it and haven’t even finished the chapter yet. Anyway, let’s start. By the way I started creating an Erlang Cheat Sheet with all the syntax on it. Being used to the very clear Ruby syntax, things started to get a bit confusing in this chapter.

I just started reading the latest book from the pragmatic programmers: Programming Erlang. In this series of articles, I’m going to summarize and comment on every chapter I read. Enjoy. (The reason I’m doing this in English is that I simply feel like writing some English again and that I hope to reach a larger audience )

What is Erlang and why read that book?

Erlang is a programming language which has things like parallel processing and functional programming features built right into the language. Software written in Erlang is therefore supposed to utilize the power of multi core processors found in today’s and future computers much better than software written in … my precious Ruby? omg.
Anyway, Erlang seems to be a language with features completely different from what I’ve seen before, so that’s my main reason to start reading about it, and we’re supposed to learn a new new language every year anyway. Let’s get started.
