Hexdunk

A basic gui hex-editor with vi bindings.

Features

• Fast loading and editing of arbitrary large files.
• Fast cut/copy/paste.
• Looks good.
• Unlimited undo/redo.
• Fully written in Go.

It uses the packages:

• "giu" (https://github.com/AllenDang/giu) as a wrapper for imgui, the graphic libary.
• "filebuf" (https://github.com/snhmibby/filebuf) for fast file loading and editing.
• "filetree" (https://github.com/snhmibby/filetree) for an imgui file-system dialog.

Manual

The following operations are supported in the hex-window:

• left click: select byte with cursor.
• right click: edit menu popup.
• mouse dragging: select bytes.
• shift clicking: extends selection.

The following keys are bound (vi like)

• h,j,k,l: move around.
• arrow keys: move around.
• g: goto address
• i: insert mode (insert bytes before the cursor).
• o: overwrite mode (overwrite bytes).
• escape: normal mode (move around/editing operations).
• x: cut.
• y: copy.
• p: paste.
• u: undo.
• r: redo.

Upcoming/planned features

• compound data inspection & editing (structs, lists, arrays, etc.)
• plugin functionality (written in go)

Installation

Disclaimer

This software is (very much) in alpha version-state. It works for simple use cases, but don't try to do complicated things. I.e. there is a bug where copying from an edited file, pasting in another, then writing the edited (1st) file to disk, could potentially change the other file-view. So keep all your write-back-to disk edits to 1 file for now :)
