hgview is an open source, freely distributed, graphical and command-line software project implemented in Python around the Qt toolkit, as a replacement for the hgk application. It is a Mercurial log navigator and interactive history viewer utility for GNU/Linux operating systems.
Features at a glance
Key features easy key-based navigation, support for mq patch queues, ability to view the revision graph for a file, basic support for the bfiles extension, ability to search the entire history, as well as the ability to navigate in the manifest of a given revision without modifying the current working folder.
In addition, the program will automatically refresh the revision graph every time a repository is modified, including updates, commits or pulls, it displays the current working folder as a special node in the current graph, but only if local changes are available, and allows you to view a graphical, side-by-side diff for a certain file, so you can easily do revisions comparisons.
It is very important to note here that the keyboard navigation can be used in revisions' history of a repository, and that you will be able to search in commit messages and diff contents. Another interesting feature is the ability to go directly to a certain revision, in any format, including branch name, rev number, tag or ID.
Under the hood and requirements
Looking under the hood of hgview, we can notice that the application has been written in the Python programming language using the PyQt and Qt technologies for its graphical user interface (GUI).
Mandatory requirements for both the graphical and command-line interfaces are Python 2.5 or later and Mercurial 1.6 or higher. While the GUI requires the PyQt4 libraries (including the dev ones), the CLI needs the urwid library, as well as the pyinotify and pygments Python modules.
