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.

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
|
|
|
|
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://ide.kaitai.io/ and https://codisec.com/veles/ are essentially what
|
|
this project wanted to be but the description language is purely declarative
|
|
* https://bitbucket.org/haypo/hachoir/wiki/Home 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
