hex

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.

At the moment the project is still in a very early stage.

Packages

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:

https://build.opensuse.org/project/repositories/home:pjanouch:git

Building and Running

Build dependencies: CMake, pkg-config, help2man, liberty (included), termo (included)
Runtime dependencies: ncursesw, libunistring, Lua >= 5.3 (for highlighting)

$ git clone --recursive https://github.com/pjanouch/hex.git
$ mkdir hex/build
$ cd hex/build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug
$ 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 on a file of your choice.

Configuration

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

colors = {
	footer     = ""
	footer_hl  = "bold"
	bar        = "reverse"
	bar_hl     = "reverse bold"
	even       = ""
	odd        = ""
	selection  = "reverse"
}

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
urxvt’s vtwheel plugin sabotages scrolling
