A debug server for WSGI apps.

Project description

build status License

OhOh is a debugger for your WSGI applications. Using OhOh, you can inspect the stack frames of a wsgi app that’s thrown an exception.

Usage

Use this command to serve your wsgi app in debug mode:

> ohoh "package.module:wsgi_app" -s localost:5000

For a full range of options, see ohoh -h

OhOh provides a plug-in for the httpie utility. You can install httpie using pip install httpie. Once you send a request that results in an exception, you will enter the debugger automatically:

> http localhost:5000
