Note: [[pdbpp]] is a better version of pdb.


My .pdbrc

alias brr print(f"\n{'='*100}\n")

alias brk print(f'\n\n{"=" * 100}\n\n')

# hack to get around the fact that imports get lost when you step into a call
# [TODO] find a better way
alias rp from rich import print as _print; _print(%1)

alias pl from rich import print as _print; _print(locals(), style="red")

alias cls import shutil; print("\n" * shutil.get_terminal_size().lines)

!!! note aliases can accept arguments using %1, %2, and so on.

!!! warning I no longer use this method since rich pretty much handles this on its own.

I like to have dictionaries printed with colors in a pdb session. I'm sure there's a better way of doing this, but here's my method:

I write a pdb util function somewhere in my code base.

# somemodule.pdb_utils.py

import json
from pygments import highlight
from pygments.lexers import JsonLexer
from pygments.formatters import TerminalFormatter

def ppd(d):
    s = json.dumps(d, indent=4, sort_keys=True, default=str)
    print(highlight(s, JsonLexer(), TerminalFormatter()))

More on this here.

Then I create an alias to this function in my ~/.pdbrc file. More on pdbrc aliases here.

alias ppi from somemodule.pdb_utils import *

Finally, in my pdb session, I can import my pdb util functions with ppi. And, print a dictionary with colors using ppd(somedict).

Use ipython inside pdb


Losing terminal echo

This might help.
