Using Charmcraft

We recommend the Charmed Operator Framework for charm development, but Charmcraft will help you publish charms written in any language. The Charmed Operator Framework enables the development of operators in a simple and straightforward way, using standard Python structures to allow for clean, maintainable, and reusable code.

Happy charming!

Hello everyone, Charmcraft 2.3.0 is now on the stable channel

Will Charmcraft 2.3.0 also be pushed to PyPI? It’s still version 2.2.0 as of today.

I’m wondering why releasing the Snap seems to be automated, but releasing the Python package isn’t. Any specific reason for this?
