Erlang code worth reading

10 points by kaeluka 15y ago ↗ HN

Hey, everyone. I'm just trying to learn some erlang, I'm working through Joe Armstrong's "Programming Erlang", which I like quite a lot, so far. BUT it would be nice to have some real world code to read as well. As I am not much more than a beginner in functional programming, this would benefit me greatly. So, my question is: what are noteworthy pieces of free erlang code on the internet? Does anyone have suggestions? thanks!

Modifying the routing mechanisms (creating my own exchange type) on RabbitMQ was where I cut my teeth on Erlang years ago. RabbitMQ is a great example of how little Erlang code is needed to produce something reliable with immense functionality.

Likewise the Mochiweb HTTP server is another great example.

All the best, it's such a beautiful language/environment.

Thanks, it really seems to be beautiful so far, I was expecting a not so beautiful and much more clumsy language. Don't know, how I ended up with this opinion. The erlang shell is very nice as well (but I know the concept from Lisp/clojure already)

I haven't done anything with Erlang in a while but perhaps these will help:

ErlyWeb, a web server/framework: http://code.google.com/p/erlyweb/

ejabberd, a chat server: http://www.ejabberd.im/

MochiWeb, a library for building lightweight HTTP servers: https://github.com/mochi/mochiweb

CouchDB, a document oriented database: http://couchdb.apache.org/

RabbitMQ, messaging middleware: http://www.rabbitmq.com/

I am just checking out CouchDB - looks _awesome_ so far. LOTS of possibilities I didn't realize until now. The official book/documentation (even though it's slightly outdated) is free and recommended.

I've been checking out Chicago Boss to get involved with Erlang on the web front.

Chicago Boss is an open-source web framework inspired by Rails and written in Erlang. http://chicagoboss.org/projects/chicagoboss/wiki

Looks like a nicely coded and laid out project.
