history

Project history and usage

Juju Charm Tools is a collection of command-line tools for creating, building, validating, and publishing Juju charms.

Project history

Canonical's Juju ecosystem uses charms as operational packages for deploying and managing applications. The charm-tools README describes this project as tools that make writing Juju charms easier, with commands for the charm authoring lifecycle.

Adoption history

The official README points users to the Snap package named `charm` for stable releases and notes PyPI availability for Python dependency use. The supplied package facts show Homebrew also packaged charm-tools for macOS users.

How it is used

The README highlights `charm create`, `charm build`, `charm proof`, `charm login`, `charm push`, `charm release`, and `charm show`; the Homebrew facts expose split executables such as `charm-build`, `charm-create`, and `charm-proof`.

Why package nerds care

charm-tools is package-nerd interesting because it predates the newer Charmcraft-centered workflow and shows Juju charm authoring distributed across Snap, PyPI, and Homebrew with both a combined `charm` interface and split command executables.
