A printing debugging helper.

Project description

dprint

A printing debugging helper.

Motivation

dprint is inspired by a python-ideas thread, to show what's possible with a little bit of magic with plain Python code.

Installation

It's on PyPI as dprint. The obvious way will just work:

pip install dprint

Usage

Import the function dprint from the dprint module.

from dprint import dprint


def spam():
    eggs = 10
    dprint(eggs * 2)

spam()

Running the above script gives:

$ python script.py
script.py:6 in spam
  eggs * 2 -> 20

Operational Assumptions

The current logic for figuring out the expression passed to dprint operates under some assumptions:

  • The imported function must be called dprint
  • A call should span no more than 1 line
  • No more than 1 call on 1 line

A future version might relax these assumptions.
