pydbg ๐ 
pydbg is an implementation of the Rust builtin debugging macro dbg
The purpose of this package is to provide a better and more effective workflow for people who are "print debuggers".
pip install pydbg
The old way:
a = 2
b = 3
print(f"a + b after instatiated = {a+b}")
def square(x: int) -> int: return x * x
print(f"a squared with my function = {square(a)}")
outputs:
a + b after instatiated = 5
a squared with my function = 4
The new (and better) way
from pydbg import dbg
a = 2 b = 3
dbg(a+b)
def square(x: int) -> int: return x * x
dbg(square(a))
outputs:
[testfile.py:4] a+b = 5
[testfile.py:9] square(a) = 4
This project is a work in progress and all feedback is appreciated.
The next features that are planned are:
- [ ] Fancy Mode (display information about the whole callstack)
- [ ] Performance Optimizations
