I've tried a lot of various hexeditors and found that hexeditors or too simple, or dead project.
And decide to improve bvi hexeditor http://bvi.sourceforge.net/ to fit my needs.

And forked it here https://gitorious.org/bvi/bvi
I'm working on implementing lua scripting, block operations, signature recognizing and templates using. currently implemented:

nice color scheme support
lua scripting (even directly in command line)
block operations (logic and not only)
various fixes.

Is there a problem with the latest version?

Nope. I'm rewriting it to migrate on event-based architecture, to implement more powerfull lua scripting, and using bvi events from lua side

Here is my current TODO http://paste.pocoo.org/show/468760/

After I'll finish some refactor - you will see new commits

ok great.

i don't think that there's a problem with the latest version...
