What happened to my slime backtrace?

Hello,

I am trying to set up slime on opensuse-11.2. The only CL implementation
that is available via official repositories is clisp, so I use this.

Slime seems to work OK on the first sight, with one exception: the backtrace
is really verbose and gives me no valuable information about the reason why
the debugger was invoked. With the example taken from
http://bc.tech.coop/blog/050501.html

(+ hello 2)

I guess I should get a backtrace like

Backtrace:
0: (EVAL HELLO)
1: (EVAL (+ HELLO 2))
--more--

But instead, I get:

Backtrace:

Is there a way to reduce verbosity to a sane amount (like shown on Clementson's Blog)?

Indeed. And this is what you get if you use clisp, in a terminal or
with M-x inferior-lisp RET:


[pjb@kuiper :0.0 ~]$ clisp -norc

I \ `+' / I 8 8 8 8 8 8

`-__|__-' 8 8 8 8 8

This is the goodness of slime for you.

> Clementson's Blog)?

Good question.


Clisp has actually five different backtrace commands: :bt1 to :bt5
You can select :btN by default for :bt with :m N
But slime does it on its own.

I complained similarly in October 2008.¹ Helmut Eller explains in his
reply that we're suffering a deficiency in CLISP, and it would take some
customization of SLIME to whittle the noise down to the more palatable
trace provided by other CL implementations.

Looks like I'll have to go and try sbcl...
