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. It also runs equally well in the terminal, or as an X11 client. 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 using Arch Linux's https://aur.archlinux.org/packages/hex-git[AUR], or as a https://git.janouch.name/p/nixexprs[Nix derivation]. Documentation ------------- See the link:hex.adoc[man page] for information about usage. The rest of this README will concern itself with externalities. Building and Running -------------------- Build-only dependencies: CMake, pkg-config, awk, liberty (included), termo (included), asciidoctor or asciidoc (recommended but optional), rsvg-convert (X11) + Runtime dependencies: ncursesw, libunistring, Lua >= 5.3 (for highlighting) + Optional runtime dependencies: x11 + xft + libpng (X11) $ 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 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 - 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://ide.kaitai.io/ and https://codisec.com/veles/ are essentially what this project wanted to be but the description language is purely declarative * https://github.com/wader/fq goes a step above, allowing transformations of identified data * https://hachoir.readthedocs.io/en/latest/ seems to be strictly hierarchical, which may not work for file formats like ELF * https://github.com/ruslashev/elfcat is a more interactive viewer for 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.
