## Project history and usage

carl is a Rust command-line calendar that deliberately resembles traditional cal(1) tools while adding color themes, iCalendar highlighting, agendas, and template customization.

### Project history

The Codeberg repository was created in December 2021 and the first tagged release, 0.0.1, was published on January 1, 2022. 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.
