Hi All,

I've put my "jump to debugger" code on github:
https://github.com/mwette/guile-jtd

jump-to-debugger is a procedure that, when called,
stops execution and fires up a REPL.  It is much like
Python's pdb.set_trace() function.

Matt

I've yet to try it, but I just wanted tip in and say thank you, as this
is something that I had been missing.

I hope you get to refine it and contribute it for inclusion into Guile
proper :-).

Thanks again,

Maxim

Hi All,

I've pushed version v220319a to my github repo.
1) Now requires --debug flag to script session:
     on-the-fly switching to debug vm is not reliable
2) added ,set-local! command
3) misc cleanup

Also, I believe I found the bug that was making line stepping swing back.
In guile-3.0.8, I changed line 913 of language/tree-il/compile-bytecode.scm
from
   (maybe-emit-source src)
to
   ;;(maybe-emit-source src)
That is, comment the line out.

Remember, this is all still experimental.

Regards,
Matt
