Erlang Development Environment

[Konstantin Weitz <ko...@gmx.de>]

  Hi all,

On my path to gain unlimited wisdom, I'm working on get a better 
understanding
of couchdb. I'm especially interested in (the) erlang (impelementation). 
I got
the svn version installed and running on my ubuntu 10.4 and followed the 
code
through a couple of files, but it is rather stressfull to io:format out 
everything
and recompile to keep track of my current location.
What Development Setups do you use? Especially a debugger, which I could 
use to
step throught the code, would be nice (I tryed using the one that one 
can start
using debugger:start(), but it seems to be very unrelaxed to compile every
single module with debugging info and attach it to the debugger by hand).

Any input on how to do this would be great.

I find Distel[1], which extends emacs, to be a very good IDE for erlang. It connects to a running erlang VM and accesses the code module, to produce support for symbolic debugging, listing processes, etc.. There is a bug in who_calls, one of the more valuable features. You can work around it by invoking who_calls once from the VM directly, .eg. distel:who_call(couch_uuids,new,0). and thereafter C-c C-d w   will do the right thing. This is very useful for navigating the code paths.

There are some docs[2] that aren't complete, but will get you started

Best,

Bob
