The project maintains an active development status with periodic updates.","status":"active","version":"0.5.3","language":"en","source_language":"en","source_url":"https://github.com/ei-grad/flask-shell-ipython","tags":["flask","ipython","shell","cli","development","interactive"],"install":[{"cmd":"pip install flask-shell-ipython","lang":"bash","label":"Install latest version"}],"dependencies":[{"reason":"This package is a Flask extension and depends on Flask for its core functionality.","package":"Flask","optional":false},{"reason":"Provides the enhanced interactive shell features that this package integrates with Flask.","package":"IPython","optional":false}],"imports":[{"note":"The primary feature of `flask-shell-ipython` is that it automatically hooks into the `flask shell` command upon installation.
