luz / hexdino

A hex editor with vim like keybindings written in Rust.

hexdino's Issues

Search for binary data

Since the search function is currently only implemented for ascii data, this would be an important need.

Undo/Redo Support

This is a nifty little tool. 👍 It would be cool if it had undo and redo functionality, mapped to the vim keybindings of course. 🙂

Panic when opening file in non-existing directory

This works:

hexdino asdf

But this results in a panic:

hexdino foo/bar/asdf

Error:

thread 'main' panicked at 'couldn't open foo/asdfreset: entity not found', src/main.rs:103:25

Adress "00000000" gets formatted as "0"

I think it gets formatted like this as soon as the number to be formatted is 15(dec) or smaller

Huge CPU and memory usage when opening big files

When opening big files (ie. images) the CPU usage is 100% while loading the file completely to RAM. Afterwards hexdino uses the size of the file as RAM.

Maybe it would make sense to only load parts of the file into RAM or use something like memmap to let the operating system handle that.

Cannot delete last byte in file

Steps to reproduce:

$ echo "hello" > test.dat
$ hexdino test.dat

Then navigate over last byte (0A) and press x to delete. Then enter :wq to save and quit.

Open the file again with hexdino, the 0A byte is still there.

No dark background enforced

hi,
I'm using terminal with clear background sometimes,
would it be possible to make background color transparent?

Thanks.
