hexhog

configurable hex viewer/editor

To run use:

hexhog <file>

Instalation

If you have cargo installed, just run:

cargo install hexhog

Alternatevely, it is available on AUR (many thanks to @dhopcs).

yay -S hexhog

I hope I can make this tool available on other package managers soon.

Features

For now hexhog allows for basic hex editing features for files, such as editing/deleting/inserting bytes, as well as selecting and copy/pasting bytes. I'm look forward to adding other features, including (but not only):

• moving the selection
• find/replace
• bookmarks
• better navigation
• CP437
• other coloring options

While I do love(and use) modal editors, hexhog does not attempt to be one. I am trying to make it as intuitive as possible :)

Configuration

Configuration file is located at:

• Linux: /home/user/.config/hexhog/config.toml
• Windows: C:\Users\user\AppData\Roaming\hexhog\config.toml
• MacOS: /Users/user/Library/Application Support/hexhog/config.toml

An example configuration file:

[theme]
null = "dark_gray"
ascii_printable = "blue"
ascii_whitespace = [67, 205, 128] # rgb
ascii_other = 162 # ansi
non_ascii = "red"
accent = "blue"
primary = "green"
background = "black"
border = "cyan"

[charset]
null = "."
ascii_whitespace = "·"
ascii_other = "°"
non_ascii = "×"

Feedback on hexhog is highly appreciated. Thanks! :D
