TortoiseHg is a set of graphical tools and a shell extension for Mercurial.
- On Windows
TortoiseHg consists of a shell extension, which provides overlay icons and context menus in your file explorer, and a command line program named thg.exe which can launch the TortoiseHg tools. Binary packages of TortoiseHg for Windows include Mercurial, TortoisePlink and a merge tool and are thus completely ready for use “Out of the Box”.
- On Linux
TortoiseHg consists of a command line thg script and a Nautilus extension which provides overlays and context menus in your file explorer. You must have Mercurial installed separately in order to run TortoiseHg on Linux. TortoiseHg binary packages list Mercurial as a dependency, so it is usually installed for you automatically.
TortoiseHg is primarily written in Python and PyQt (the Windows shell extension being the notable exception). The thg script and TortoiseHg dialogs can be used on any platform that supports PyQt, including Mac OS X.
