Mercurial is a platform-independent, distributed version control system for software development. It is developed almost entirely in Python : only a diff implementation that can handle binary files is implemented in C. Mercurial is used primarily from the command line; All commands start with " hg ", the element symbol of mercury ( English mercury ).
Mercurial's development focuses on efficiency, scalability and robust handling of text and binary files. With Mercurial, the repository of the project that you want to develop is "cloned", ie a local copy is created. The usual functions are then available on this local copy, for example creating new revisions, called a changeset .
The ability to create and merge development branches ( " branching " and " merging " ) is an integral part of Mercurial. An integrated web interface is available; Third-party providers provide graphical front ends or plugins for development environments.
history
On April 19, 2005, Mercurial was announced by Matt Mackall on the Linux kernel mailing list. The decisive factor was the announcement by BitMover , which z. B. BitKeeper software used as the version control system for the Linux kernel is no longer available in a free version. Around the same time, Linus Torvalds had started his own project called Git , which had similar goals as Mercurial.
Git is officially used for the Linux kernel, but there are also kernel developers who use Mercurial.
distribution
Mercurial is used by many well-known software projects and companies. It is used, among others, by Facebook , Mozilla ( Firefox , Thunderbird ), SourceForge , Google Inc. ( Google Code ), Atlassian ( Bitbucket ), Microsoft ( CodePlex ), Oracle ( OpenJDK ), Xen , NetBeans IDE , Python , Dovecot , and Nginx .
Graphic interfaces
For Microsoft Windows and Gnome / Nautilus is the graphical interface TortoiseHg and macOS with MacHg and Murky , one each to-use frontend available which allows easy use of Mercurial without command line commands.
Various integrated development environments such as Netbeans , Eclipse , Android Studio , Delphi or the Qt Creator support Mercurial directly from the graphical user interface, usually through a plug-in that is either supplied or installed later. MercurialEclipse also allows you to work with patch queues (mq).
