Its README identifies Birger Schacht as the copyright holder for 2021-2023 and documents a compact CLI installed with cargo. ### Adoption history carl is a niche terminal productivity tool rather than a large platform project. Its adoption path is typical for Rust command-line software: upstream publishes source and cargo installation instructions, while package managers such as Homebrew, MacPorts, and Nix make the executable available outside Cargo workflows. ### How it is used Users run carl to print one month, three months, a year, Julian dates, or a specified date. Configuration can point to iCalendar files or directories, select themes, and configure custom Jinja templates. ### Why package nerds care For package nerds, carl is a tidy example of a modern replacement for a small Unix utility: it keeps the old terminal shape of cal(1), but adds XDG configuration, iCalendar awareness, theming, and Rust packaging. ### Timeline - 2021: Codeberg repository created. - 2022: 0.0.1 tagged as the first release. - 2023: 0.0.3 released on Codeberg. ### Related projects - carl explicitly positions itself next to cal(1) implementations. - Its iCalendar support connects it to the broader family of terminal calendar and agenda tools. ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
