Small hex viewer. WIP.

Blaxor

A small hex viewer. Work in progress. Works on both Windows and Linux. I don't recommend using it yet unless you're up for a challenege. If you're interested but can't/don't want to build it or want to know all the controls then let me know in an issue here. If you want to look for the keys to do search, switch to binary and upper/lowercase hex display, change font size, etc. yourself they are all/mostly in int BlaHexDisplay::handle(int event).

Uses:

1. FLTK 1.3.5 (external dependency, not included in this repo).
2. UTF-8 DFA decoder (fully in utf8dfa.hpp and utf8dfa.cpp).

Written for fun, to get familiar with FLTK (a C++ GUI library I once saw used in one game mod's config utility) and for my own use because it's hard to find a simple, light, good and free hex viewer/editor. Blaxor is not an editor yet (just a viewer) but it might be one in the future.

I use XVI32 and it's good and simple program but it has a few shortcomings I ran into too. It doesn't seem to handle non-ASCII Unicode filenames (an error message with garbled filename pops up), it's freeware but closed source, Windows only with a license that forbids reverse engineering and modification. It also seems to load entire file (or big part of it) into memory, taking seconds to load a few GB file off of a HDD and for files starting at about 5 GB it'll just display an error message about not being able to allocate memory (probably since it's a 32-bit program). I specifically avoid all these problems in Blaxor.
