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 there aren't that many features and we only have a few decoders. image::hex.png[align="center"] 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. 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://git.janouch.name/p/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 Performance ----------- 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 can't help us here. Similar software ---------------- * https://codisec.com/veles/ can also highlight files but it's not scriptable * https://bitbucket.org/haypo/hachoir/wiki/Home seems to be strictly hierarchical, which may not work for file formats like ELF Contributing and Support ------------------------ Use https://git.janouch.name/p/hex to report any bugs, request features, or submit pull requests. `git send-email` is tolerated.
