Python Debugging - pdb++ (python debugger plusplus)

[Buddy Hy]

Hey Kunda1, I'm looking for the pdbpp code debugger but all I can find is the pdb module. Could you please supply a link to where we can download the pdbpp module?

Mod Edit: This thread was split from another thread because it was off-topic. The context of this thread started from the following youtube video on how to use pdb++

You can get it through pypi via pip or through your distribution installer (in Manjaro i use pacman to install it)
https://pypi.org/project/pdbpp/
https://github.com/pdbpp/pdbpp

Awesome Kunda1, I've downloaded the zip file but GitHub doesn't properly detail how to install it - All it says is:

Installation

Since pdb++ is not a valid package name the package is named pdbpp:

$ pip install pdbpp

pdb++ is also available via conda:

$ conda install -c conda-forge pdbpp

Alternatively, you can just put pdb.py somewhere inside your PYTHONPATH.

So do I just replace pdb.py in 'FreeCAD\bin\lib\'?

Yea, their documentation is alarmingly sparse.
I haven't installed a python package manually in a while...
Is there are reason why you're not interested in using a package installer for python...
I'm not a python expert, FYI.

Alternatively, you can just put ``pdb.py`` somewhere inside your
``PYTHONPATH``.

So yea, it seems you can add the location of the pdbpp's pdb.py to the beggining of your PYTHONPATH environmental variable (not sure how to do this on Windows).

Once you install pdbpp it should of automagically become you new python debugger.

Here is a nice indepth page:

Follow these instructions, they should work.

I can't see a package installer for pdb++... I wonder if I downloaded the correct file?

[Kunda1]

Did it work out ?

[Buddy Hy]

Sorry Kunda, I can't remember exactly what I did any more - but I seem to remember that I didn't really need the debugger. Anyways I finished the project, so I suppose this thread can be closed.
Thanks to everyone who tried to help.

I was able to get pdbpp to work without the FreeCAD GUI invoked. Which is nice. I'll post instructions on how to do that. The problem really is that it's not possible to do the same when FC GUI is active.

I've never really used pdb from within FreeCAD but I'm trying to up my debugging game.

I do a import pdb; pdb_set_trace() in the console and get the pdb prompt.
some of the commands work but behavior is strange. For instance, the short form of most commands does not work. c does not work but cont does.
h does not but help does.

If I use the help command, nothing else works after that point. Every command just re-runs help.
Once it's in this locked condition, the only way out I've found is to restart FreeCAD.

So I'm a total newbie here. What the heck am I doing wrong?
