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. ### Timeline - 2013: juju/charm-tools public GitHub repository created. - 2021: Read the Docs build metadata shows charm-tools documentation generated from the GitHub docs tree. - 2023: GitHub releases include v3.0.x and v2.8.x maintenance lines. - 2024: v2.8.9 release published. ### Related projects - Juju is the orchestration system whose charms this tool helps author and maintain. - charmstore-client provides the Charm Store client commands used for charm store interactions. - Charmcraft is the newer Canonical charm authoring tool in the same ecosystem. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** charm-tools - **Version Scheme:** 0 - **Revision:** 5 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [charm](https://www.automicvault.com/pkg/brew/charm/) - Runtime dependency declared by Homebrew. - [python@3.14](https://www.automicvault.com/pkg/brew/python-3-14/) - Runtime dependency declared by Homebrew. - [charmcraft](https://www.automicvault.com/pkg/brew/charmcraft/) - Shares av.db curated category or tags: charms, cli, developer-tools, juju. - [cobo-cli](https://www.automicvault.com/pkg/brew/cobo-cli/) - Both packages touch the same language runtime or ecosystem.
