Very much work in progress, lightweight interactive hex inspector.
Guaranteed broken in terrible ways but also might be just good enough. Could eat your laundry.
You'll need a reasonably recent rust compiler, with that sorted run:
cargo run --release [filename]
Have a look at src/bin/hi.rs and guess at keyboard shortcuts, the key section reproduced here for convenience:
Event::Key(Key::Char('q')) => return Ok(HandlerStatus::Quit),
Event::Key(Key::Char('h')) => screen.scroll_left(),
Event::Key(Key::Char('l')) => screen.scroll_right(),
Event::Key(Key::Char('j')) => screen.down(),
Event::Key(Key::Char('k')) => screen.up(),
Event::Key(Key::Char(':')) => screen.prompt(),
Event::Key(Key::Char('f')) => screen.toggle_text_display_mode(),
Event::Key(Key::Ctrl('d')) | Event::Key(Key::PageDown) => screen.page_down(),
Event::Key(Key::Ctrl('u')) | Event::Key(Key::PageUp) => screen.page_up(),
Event::Key(Key::Home) => screen.start(),
Event::Key(Key::End) => screen.end(),
You can run enter command mode by pressing :. Once there type your command in and press Enter.
Supported commands are:
o(ffset) N # set offset from beginning of file
w(idth) N # set number of horizontal bytes to display
scroll(x) N # scroll to a certain row
scroll(y) N # scroll to a certain column
