## What it is
Pyringe is a Python debugger that can attach to running CPython processes, inspect their state (threads, tracebacks, locals/globals), and inject Python code into them without prior preparation. It relies on gdb under the hood and only supports Python 2.

## Use cases
- attach a debugger to a running python process
- inspect locals and globals of a live python program
- inject python code into a running process
- get tracebacks from a stuck python process
- debug python stuck in a C extension
- inspect a python process without stopping it

## When to choose
- you need to debug a live Python 2 process that cannot be stopped or restarted
- the interpreter is stuck in a C extension and PDB cannot help
- you want to inspect state of a running process without preparing it in advance

## When to avoid
- you are running Python 3 (unsupported)
- you use PyPy instead of CPython
- you need a maintained tool - the project has not been updated since 2019
- you cannot install gdb with python support and debug symbols for your Python build
