Open Source Perl Git Software

Gitslave is a script for coordinated version control of large projects combining code from multiple independent repositories using Git. More flexible than traditional git submodules, gitslave provides a simple wrapper around command-line git that manages a directory tree with multiple subsidiary ("slave") git repositories in sub-directories of a "master" git repository. Any git command run from the "gits" wrapper will be performed in all the git repositories; for example gits checkout -b newbranch will create the new branch in all repositories. Gitslave has been used for mid-sized product development with many slave repositories (representing different programs and plugins), branches, tags, and developers; and for single-person repositories tracking groups of .emacs and .vim repositories (in the latter case, it is basically used to keep the slave repositories up to date via a single command).

GitPrep is a lightweight, self-hosted web interface for browsing Git repositories, typically deployed on a single server with minimal dependencies. It implements features like commit history browsing, file viewing and diffing, directory tree navigation, tag/branch switching, and README rendering, much like GitHub’s core UI. Because it’s written in Perl and designed for simplicity, setup is often as easy as cloning, configuring a webroot, and pointing to repositories. Authentication and basic permissions can be configured, allowing private or team usage. Unlike full-featured Git lab or hosting suites, GitPrep focuses on just the browser view of repositories, staying lean and ideal for small teams or personal use. It’s sufficient for code review, history tracing, and lightweight dev workflows when elaborate ticketing or CI integrations aren’t required.

Gitolite is a lightweight Git server and access-control system that lets many human users share a single Unix account while enforcing fine-grained permissions. Configuration is “as code”: you manage users’ SSH keys and per-repo rules in a special admin repository, then push to apply changes instantly. Permissions are precise—read, write, or force-push can be allowed or denied per repository, branch, tag, or arbitrary ref patterns—so sensitive branches can be protected. Delegation features let large organizations hand off subsets of administration without giving away global control, and “wild” repositories make self-service project creation possible within policy. Hooks, logging, and auditing are baked in, giving visibility into who pushed what and when. Because it rides on plain SSH and standard Git, it’s fast, portable, and easy to host on anything from a low-power VPS to an enterprise server.

git-cal generates a terminal-friendly contribution calendar for your Git activity, echoing the familiar heatmap seen on hosting sites but rendered in plain text. It scans your repositories’ commit history and aggregates changes per day, then prints a compact grid that highlights streaks and quieter periods. The output works in standard shells, making it handy for dashboards, status emails, or a lightweight snapshot of productivity without opening a browser. Options typically let you choose time ranges, color intensity (where terminals support it), and which repositories to include. Because it reads local Git metadata, it respects your privacy and can include private work you don’t push to public remotes. For developers who like quick visual feedback in the CLI, git-cal turns raw commit timestamps into an at-a-glance activity portrait.
