Hexcellent

A hex editor. Includes these features:

  • Does not require an existing file to edit
  • Unlimited undo and redo
  • Full copy and paste functionality of both hex and text
  • Find and replace
  • Customizable font and color scheme
  • User-settable text encoding
  • Data inspector supporting both big-endian and little-endian values

Power Keys

When Power Keys are enabled and the focus is on the hex side of the editor, the following keys will have the following effects:

  • Z - Replace selection with all zeros (00 00)
  • Y - Replace selection with all ASCII spaces (20 20)
  • X - Replace selection with all ones (FF FF)
  • I - Invert selected bits (00 00FF FF and vice versa)
  • V - Replace selection with random data
  • S - Swap selected bytes / reverse endianness (01 0202 01 and vice versa)
  • N - Swap selected nybbles (12 3443 21 and vice versa)
  • R - Swap selected bits (80 0000 01 and vice versa)
  • [ - Rotate selected bits to the left (ROL)
  • ] - Rotate selected bits to the right (ROR)
  • < - Shift selected bits to the left (ASL)
  • > - Shift selected bits to the right with sign extension (ASR)
  • ? - Shift selected bits to the right with zero extension (LSR)
  • + - Increment selected value
  • - - Decrement selected value
  • H - Switch between hex and decimal addresses
  • L - Switch between big and little endian

The Backstory

I went looking for a (graphical) hex editor on Linux. After trying several (GHex, Bless, Okteta, wxHexEditor), I was disappointed to find not a single one that didn't have at least one of the following issues:

  • Requires an existing file to edit
  • Copy and paste limited to the text side
  • Copy and paste limited to the hex side
  • Copy and paste on the hex side picky about whitespace
  • Copy and paste completely broken
  • Saving completely broken

I had had enough of everything I tried not getting the basics right and decided to do what I always do in these situations: write my own. I had in fact already written one years ago, inspired by an old Macintosh program called HexEdit, as part of a project called Resplendence. So I took a look at my decade-old code, said "what a mess," started over, and rewrote it as a standalone application.

Be hexcellent to each other.
