I have been going through the debugging infrastructure and can’t figure out how to code in a trap.  I would like something like

(define (xxx) … (if cond (trap-here)) ….)

that would dump me into the interactive debugger when I hit that condition.  Any help on achieving this is will be appreciated.

I use this a lot in python:
#!/usr/bin/python

import pdb

def xxx:
    …
    if cond:
        pdb.set_trace()
    ….

Something along these lines on 2.0:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(system repl repl)
scheme@(guile-user)> ,use(system repl debug)
scheme@(guile-user)> (start-repl #:debug (make-debug (stack->vector (make-stack #t)) 0 "trap!" #t))
scheme@(guile-user) [1]> 
--8<---------------cut here---------------end--------------->8---

In 2.1, ‘make-debug’ does not take this last #t argument.

HTH!

Thanks for the lead.  Though this does not seem to be working, I will try to use this as a starter after I finish my current task (on nyacc).
