Using breakpoint with ipdb

17/06/2020 | Autor: Eduardo Enriquez

Since Python 3.7 we have breakpoint() as a way of replacing the traditional import pdb; pdb.set_trace().

But if we use another third party library as pudb, ipdb, rpdb,  we can not use it.

But the PYTHONBREAKPOINT environment variable can be set to the name of a callable.

The way of using that environment variable is easy as exporting it:

export PYTHONBREAKPOINT=ipdb.set_trace
# or
export PYTHONBREAKPOINT=pudb.set_trace
export PYTHONBREAKPOINT=wdb.set_trace


# if we don't want to set the env we can also do:

PYTHONBREAKPOINT=ipdb.set_trace python3 main.py

If you want to add more context to the code that you are debugging (if you want to see more lines) you can do

ipdb.set_trace(context=21)

# or 

breakpoint(context=21)

.
