Is it possible to use bpython as a full debugger?

Question

I would like to use the bpython interpreter for debugging. My question is similar to \"Is it possible to go into ipython from code?\", which asks about ipython.

If you

Answer 1

If you are looking for a cooler looking debugger that does completion and syntax highlighting you might want to take a look at pdb++. http://pypi.python.org/pypi/pdbpp/

It's a drop in replacement for pdb. So you can continue to use

 import pdb; pdb.set_trace()

and it'll drop you into the pdb++ prompt.

Answer 2

Yes, using this wrapper, which you can also access by adding the statement import bpdb to your code. Add bpdb.set_trace() wherever you want to break, and from the pdb interpreter enter "B" to jump into a bpython session with everything from the stack frame:

Your question seems perfectly valid to me!
