Hi there,
learing elisp is fun, but debugging isn't for me at the moment.
From ruby and from python I'm spoiled with additional info like
Error X in file Y line Z
but my *Messages* buffer just tells me:
error in process filter: Wrong type argument: listp, [...]
What do you do in that case to find out which line of your code creates
that error?
Thanks,
Martin

`M-x toggle-debug-on-error is the first thing that comes to mind. Or do
`M-x debug-on-entry RET <your_function> RET'. Make sure the relevant
functions are not byte-compiled. And read up on the debugger:
(info "(elisp) Debugging")
(info "(elisp) Debugger")

Also, Edebug comes to mind.
Best,

Other people have suggested reading the manual regarding debugging and Edebug in particular; I'd agree with that. However, *Messages* really should report from where and when a message arrived. I used the following as a basis for my own tweaking:
http://www.emacswiki.org/emacs/DebugMessages
By itself, I think the above hack is a bit too noisy. In particular, it interrupts completion in the minibuffer.
