Simple (small) and good erlang opensource project to learn from?

Question

Hi, I'm looking for a simple (small) opensource project in erlang, from which I can learn.

I've already found a promising looking one: http://github.com/mochi/mochiweb

Can you guys suggest more? Thanks!

Answer 1

With Erlang being the insanely productive language that it is, most projects are small. RabbitMQ, a full-featured and robust message queue engine, weighs in at under 8 kSLOC, and Disco, a distributed computation engine is under 2 kSLOC of Erlang, according to their FAQ (the source tree is about 10 kSLOC, but includes third-party stuff like MochiWeb).

Answer 2

You may want to check some Basho libs like Bitcask, Riak_Core and Rebar. Bitcask is especially interesting as it interfaces with a tiny bit of C code so you can learn that as well.

Then you may also check some client libraries to databases such as CouchBeam, riak-erlang-client and erldis.

All of these have nice code and are manageable in size. Later you can check some larger code bases such as Nitrogen and ErlyVideo.

Answer 3

You could also look at some libraries, e.g. http://github.com/erlang/otp/tree/dev/lib/stdlib/src/ and http://github.com/joearms/elib1/tree/master/lib/src/
