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 warn users of quitting before saving, it does not store backups if killed or crashing, and there is no undo option after deleting a byte.

heh is currently only available via cargo:

cargo install heh

From heh --help:

...
Terminal UI Commands:
    =                   Increase the stream length by 1
    -                   Decrease the stream length by 1
    CNTRLs              Save
    CNTRLq              Quit

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.
