A terminal UI to edit bytes by the nibble.

heh

The HEx Helper is a cross-platform terminal UI used for modifying file data in hex or ASCII. It aims to replicate some of the look of hexyl while functionaly acting like a terminal UI version of GHex.

heh is currently in alpha - it's not ready to be used in any production manner. Notably, it does not store backups if killed or crashing and there is no undo option after deleting a byte.

Installation and Usage

heh is currently only available via cargo:

cargo install heh

From heh --help:

...
Terminal UI Commands:
    ALT=                Increase the stream length by 1
    ALT-                Decrease the stream length by 1
    CNTRLs              Save
    CNTRLq              Quit
    CNTRLj              Jump to Byte

Left-clicking on a label will copy the contents to the clipboard.
Left-clicking on the ASCII or hex table will focus it.

Zooming in and out will change the size of the components.

USAGE:
    heh <FILE>

ARGS:
    <FILE>
