hex is yet another hex viewer. It automatically interprets fields within files using a set of Lua scripts, colorizing them and showing descriptions on the side. It also runs equally well in the terminal, or as an X11 client.

At the moment there arent that many features and we only have a few decoders.



Regular releases are sporadic. git master should be stable enough. You can get a package with the latest development version using Arch Linuxs AUR, or as a Nix derivation.


See the man page for information about usage. The rest of this README will concern itself with externalities.

Building and Running

Build dependencies: CMake, pkg-config, awk, liberty (included), termo (included), asciidoctor or asciidoc (recommended but optional)
Runtime dependencies: ncursesw, libunistring, Lua >= 5.3 (for highlighting)
Optional runtime dependencies: x11, xft

$ git clone --recursive
$ 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

Having the program installed, optionally create a configuration file and run it on a file of your choice.

Terminal caveats

Terminals are somewhat tricky to get consistent results on, so be aware of the following:

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

  • urxvts 'vtwheel' plugin sabotages scrolling


While the Lua API has been made considerably easy to write new decoders with, the design is far from efficient as we make tons of new formatted strings. Since we need Lua 5.3 features (64-bit integers), LuaJIT cant help us here.
