Full-screen console debugger for Python

Its goal is to provide all the niceties of modern GUI-based debuggers in a more lightweight and keyboard-friendly package. PuDB allows you to debug code right where you write and test it–in a terminal. If you’ve worked with the excellent (but nowadays ancient) DOS-based Turbo Pascal or C tools, PuDB’s UI might look familiar. Here’s a screenshot: You may watch a screencast, too. Features Syntax-highlighted source, the stack, breakpoints and variables are all visible at once and continuously updated. This […]

An improbable web debugger through WebSockets

Description wdb is a full featured web debugger based on a client-server architecture. The wdb server which is responsible of managing debugging instances along with browser connections (through websockets) is based on Tornado. The wdb clients allow step by step debugging, in-program python code execution, code edition (based on CodeMirror) setting breakpoints… Due to this architecture, all of this is fully compatible with multithread and multiprocess programs. wdb works with python 2 (2.6, 2.7), python 3 (3.2, 3.3, 3.4, 3.5) […]

Websocket

In-process service that will accept unix domain socket connections and present the stacktraces

Manhole is in-process service that will accept unix domain socket connections and present the stacktraces for all threads and an interactive prompt. It can either work as a python daemon thread waiting for connections at all times or a signal handler (stopping your application and waiting for a connection). Access to the socket is restricted to the application’s effective user id or root. This is just like Twisted’s manhole. It’s simpler (no dependencies), it only runs on Unix domain sockets […]
