# Install git-cal with Homebrew, MacPorts GitHub-like contributions calendar but on the command-line. Version 0.9.1 via Homebrew; verified from local package data. ## Install ```sh sudo av install brew:git-cal ``` Additional install commands: ### macOS - Homebrew (100%): ```sh brew install git-cal ``` Evidence: local Homebrew formula metadata - MacPorts (94%): ```sh sudo port install git-cal ``` Evidence: MacPorts ports tree: devel/git-cal/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Package facts - **Package key:** brew:git-cal - **Package manager:** Homebrew - **Package manager page:** - **Version:** 0.9.1 - **Source summary:** GitHub-like contributions calendar but on the command-line - **Homepage:** - **Repository:** - **Upstream docs:** - **License:** MIT - **Source archive:** - **Generated:** 2026-07-08T07:18:31+00:00 ## Executables - git-cal (cli) - git-cal (alias) ## Install behavior - Post-install hook: not defined - Bottle: available on all ## Freshness - Page generated: 2026-07-08 - Package-manager version: 0.9.1 - Local data: ok - Upstream repository: https://github.com/k4rthik/git-cal - Upstream latest detected: v0.9.1 (current) - info: No package-manager update timestamp was available. ## Project history and usage git-cal is a small Perl command-line tool that renders a GitHub-style contributions calendar from local Git history. It reflects a developer-tools pattern of borrowing familiar forge visualizations and making them available inside the terminal. ### Project history The project is distributed from Karthik's GitHub repository and packaged as a single executable Perl script. Its repository exposes v0.9 and v0.9.1 tags, and the Homebrew formula packages v0.9.1 from the official GitHub archive. ### Adoption history The adoption evidence is modest: the project appears in Homebrew and MacPorts package records, with the official README documenting Homebrew installation. That points to a niche utility used by command-line Git users rather than a broad ecosystem project. ### How it is used Practitioners run git-cal inside or against a repository to inspect commit activity over roughly a year. Options support ANSI color, ASCII, Unicode output, author filtering, all-branch history, and path-limited history, making it useful for quick local activity summaries without opening a hosted forge. ### Why package nerds care For package catalogs, git-cal is notable mostly as a tiny Unix-style Git companion: one executable, no CPAN dependencies declared in Makefile.PL, and behavior driven by Git log output. ### Related projects - git-cal relates to contribution graphs in hosted Git forges, especially GitHub's contribution calendar. ### 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:** git-cal - **Version Scheme:** 0 - **Revision:** 1 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - MacPorts - git-cal: normalized package name match | MacPorts ports tree: devel/git-cal/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 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. - [aicommit](https://www.automicvault.com/pkg/brew/aicommit/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [aicommit2](https://www.automicvault.com/pkg/brew/aicommit2/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [aicommits](https://www.automicvault.com/pkg/brew/aicommits/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [braid](https://www.automicvault.com/pkg/brew/braid/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [cig](https://www.automicvault.com/pkg/brew/cig/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [codeberg-cli](https://www.automicvault.com/pkg/brew/codeberg-cli/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [commitizen](https://www.automicvault.com/pkg/brew/commitizen/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [commitlint](https://www.automicvault.com/pkg/brew/commitlint/) - Shares av.db curated category or tags: cli, developer-tools, git, version-control. - [git-delete-merged-branches](https://www.automicvault.com/pkg/brew/git-delete-merged-branches/) - Package names and metadata indicate a similar tool family.
