ViewVC (formerly known as ViewCVS) is a Python/CGI-based system for viewing and interacting with Subversion and CVS repositories through your Web browser. It can browse directories, view changelogs, generate diffs, view arbitrary revisions, and display annotated ("blame") listings. It has full support for tags and branches, and contains a database-backed query system like Bonsai. It was initially based on the cvsweb work by Henner Zeller, but has been ported to Python and dramatically enhanced.
pwgrep is a simple password manager that manages a database file using encryption of GnuPG. It uses encryption and version control on all of the passwords that are stored. The password database can be used on several hosts at once with automatic synchronization. Even several users can share the same password database. The versioning system will keep track of who was changing which entries and at which time. The versioning system to use can be configured (and is Subversion by default). Besides passwords, pwgrep can also be used for storing a collection of files like certificates. The file shredding command for secure deleting of temporary files can be configured. A local backup of all database changes is automatically made. It can be used without a GUI (such as through an SSH session).
zpub is a server to collaboratively work on DocBook-based documentation. Editors modify the XML sources with their preferred editor and submit their changes via Subversion. zpub renders the files centrally to various output formats, optionally notifies other editors, provides an archive of all previous revisions of the document, and supports a simple sign-off workflow. The documentation and user interface is currently only available in German.
Submin provides a Web-based admin interface to your Subversion and Git repositories. Its features include user/group management, path permission management, the ability to create svn repositories and managing commit email messages. For Subversion, authentication is done with htpasswd/svn authz, so it can use the same login information as apache2/svn (and trac). For Git, ssh is used, and the login information is synched whenever a change is made. The Web interface can also work with NGINX/uWSGI, but the Subversion part only works with Apache.
XML-Grammar-Fiction is a Perl package that provides processors for lightweight markup languages and corresponding XML grammars for writing prose (e.g. stories, novels, and novellas) as well as screenplays. The XML grammars can in turn be translated to XHTML and DocBook/XML. XML-Grammar-Fiction currently offers only very basic functionality, but has good support for UTF-8 and allows one to write bidirectional texts conveniently. It is still under development and may exhibit some quirks.
OpenGrok is a fast and usable source code search and cross reference engine. It helps you search, cross-reference, and navigate your source tree. It can understand various program file formats and version control histories like Mercurial, Bazaar, Git, ClearCase, Perforce, SCCS, RCS, CVS, or Subversion. In other words, it lets you grok (profoundly understand) the source.
FishEye opens your source code repository to help you understand your code and keep tabs on the people who write it. It lets you view user activity, track code changes, and search and navigate through your repository from any Web browser. Nearly everything in your repository has its own URL, down to every single line of code for every revision. Files, branches, repositories, projects, and even people have their own activity stream. FishEye provides easy navigation, powerful search, historical reporting, configurable file annotation and diff views, changeset analysis, RSS feeds, and integration with JIRA, Crucible, Bamboo, Eclipse, and IntelliJ IDEA. FishEye works with Subversion, CVS, Perforce, Git or Mercurial.
pepper is a commandline tool for retrieving statistics and generating reports from source code repositories. It ships with several graphical and textual reports, and is easily extensible using the Lua scripting language. It includes support for multiple version control systems, including Git and Subversion.
SmartSVN is a feature-rich and easy-to-use Subversion client. It runs on Linux, Mac OS X, Unix, and Windows. In addition to the normal SVN commands like checkout, update, commit, merge, etc., it provides tag and branch handling (no need to deal with URLs just to switch to a different tag or branch), a built-in file compare and conflict solver, and much more. There is no need to install additional tools for handling SVN working copies, like a command line SVN client or a file comparison tool.
