Trac is a minimalistic web-based software project management and bug/issue tracking system. It provides an interface to the Git and Subversion revision control systems, an integrated wiki, flexible issue tracking and convenient report facilities.

The vc-dwim package contains two tools, "vc-dwim" and "vc-chlog". vc-dwim is a tool that simplifies the task of maintaining a ChangeLog and using version control at the same time, for example by printing a reminder when a file change has been described in the ChangeLog but the file has not been added to the VC. vc-chlog scans changed files and generates standards-compliant ChangeLog entries based on the changes that it detects.

This package is an implementation of Git's wildmatch.c-style pattern matching.

diff-so-fancy strives to make your diffs human readable instead of machine readable. This helps improve code quality and helps you spot defects faster.

CVS is a version control system, an important component of Source Configuration Management (SCM). Using it, you can record the history of sources files, and documents. It fills a similar role to the free software RCS, PRCS, and Aegis packages.

fnc uses ncurses and libfossil to create a fossil user interface in the terminal. It can view local changes at the hunk level to prepare atomic commits.

Fossil is a distributed source control management system which supports access and administration over HTTP CGI or via a built-in HTTP server. It has a built-in wiki, built-in file browsing, built-in tickets system, etc.

The b4 command is designed to make it easier to participate in patch-based workflows for projects that have public-inbox archives.

Features include:

• downloading a thread's mbox given a message ID

• processing an mbox so that is ready to be fed to git-am

• creating templated replies for processed patches and pull requests

• submitting cryptographic attestation for patches.

hut is a CLI tool for sr.ht. It helps you interact with sr.ht's public services:

builds

submit and manage build jobs

git

create, and manage git repositories and artifacts

hg

list Mercurial repositories

lists

manage mailing lists and patches

meta

manage PGP, and SSH keys

pages

publish and manage hosted websites

paste

create and manage pastes

todo

create and manage trackers, tickets

graphql

interact with GraphQL APIs directly

vcsh version-controls configuration files in several Git repositories, all in one single directory. They all maintain their working trees without clobbering each other or interfering otherwise. By default, all Git repositories maintained via vcsh store the actual files in $HOME, though this can be overridden.

This package provides a way of visualizing a heat map of a git repo.

ghq provides a way to organize remote repository clones, like go get does. When you clone a remote repository by ghq get, ghq makes a directory under a specific root directory (by default ~/ghq) using the remote repository URL's host and path.

Pre-commit is a multi-language package manager for pre-commit hooks. You specify a list of hooks you want and pre-commit manages the installation and execution of any hook written in any language before every commit.

Breezy (brz) is a decentralized revision control system. By default, Breezy provides support for both the Bazaar and Git file formats. Breezy is backwards compatible with Bazaar's disk format and protocols. One of the key differences with Bazaar is that Breezy runs on Python 3.3 and later, rather than on Python 2.

Git is a free distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

GNU CSSC provides a replacement for the legacy Unix source code control system SCCS. This allows old code still under that system to be accessed and migrated on modern systems.

Script that copies a directory to the gh-pages branch (by default) of the repository.

StGit uses a patch stack workflow. Each individual patch focuses on a single concern, while a stack of patches forms a series of commits. Patches are stored as normal git commits, allowing easy merging of StGit patches into other repositories using standard Git.

Features include:

• Import and export patches from Git with stg commit and stg uncommit

• Create new patches and add them to the stack with stg new

• Update a patch from the working tree with stg refresh and stg edit

• See information about the stack or patch with stg series and stg show

• Export and send a series of patches by email using stg email

Evolve is a Mercurial extension for faster and safer mutable history. It implements the changeset evolution concept for Mercurial.

blame outputs an annotated revision from each RCS file. An annotated RCS file describes the revision and date in which each line was added to the file, and the author of each line.

This package reads and writes loose and packed (objects found in git packfiles) Git objects. It uses the pack package to search pack index files and locate the corresponding delta-base chain in the appropriate pack file. If gitobj can't find a loose object with the appropriate SHA-1, it will search the repository's packfile(s) instead. If it finds an object in a packfile, it will reconstruct the object along its delta-base chain and return it.

Shell Flags (shFlags) is a library written to greatly simplify the handling of command-line flags in Bourne based Unix shell scripts (bash, dash, ksh, sh, zsh). Most shell scripts use getopt for flags processing, but the different versions of getopt on various OSes make writing portable shell scripts difficult. shFlags instead provides an API that doesn't change across shell and OS versions so the script writer can be confident that the script will work.

This package provides pijul, a sound and fast distributed version control system based on a mathematical theory of asynchronous work.

The git-extras package provides a collection of additional git commands for repository metrics and summarization, commit and log editing, developer workflow, and project and release management.
