Hex viewer
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.


hex is yet another hex viewer. As of now, there are no advantages to it.


In the future, it should be able to automatically interpret fields within files via a set of Lua scripts.


Regular releases are sporadic. git master should be stable enough. You can get a package with the latest development version from Archlinux's AUR, or from openSUSE Build Service for the rest of mainstream distributions. Consult the list of repositories and their respective links at:

Building and Running

Build dependencies: CMake, pkg-config, help2man, liberty (included), termo (included)
Runtime dependencies: ncursesw, libunistring

$ git clone --recursive https://github.com/pjanouch/hex.git
$ mkdir hex/build
$ cd hex/build
$ make

To install the application, you can do either the usual:

# make install

Or you can try telling CMake to make a package for you. For Debian it is:

$ cpack -G DEB
# dpkg -i hex-*.deb

Note that for versions of CMake before 2.8.9, you need to prefix cpack with fakeroot or file ownership will end up wrong.

Having the program installed, optionally create a configuration file and run it.


Create ~/.config/hex/hex.conf with contents like the following:

colors = {
	header     = ""
	highlight  = "bold"
	bar        = "reverse"
	bar_active = "ul"
	even       = ""
	odd        = ""
	selection  = "reverse"

Terminal caveats

This application aspires to be as close to a GUI as possible. It expects you to use the mouse (though it's not required). Terminals are, however, somewhat tricky to get consistent results on, so be aware of the following:

  • use a UTF-8 locale to get finer resolution progress bars and scrollbars

  • Xterm needs XTerm*metaSendsEscape: true for the default bindings to work

  • urxvt's vtwheel plugin sabotages scrolling
