This is loa, a debugger written in Python.
This is not a Python debugger the way pydb is. It is intended as a
replacement for gdb, but written in a (more) sensible language. It was
born out of frustration with gdb's poor scripting and inane implementation
bugs. Hopefully it succeeds in delivering a different set of bugs.
The name comes from voodoo, in which loa are powerful spirits appealed to
and/or served by humans. The imagery of invoking an intermediary to
address your problems is completely intentional, up to and including any
consequent problems the loa themselves give you. The /loa loa filariasis/
nematode and the Hawai'ian volcano Mauna Loa are not intentional
namesakes, though the additional imagery there is a pleasant coincidence.
If you want to play with it, say:
