ddhx is a (soon to be) TUI hex editor that replaces my old 0xdd viewer.

I made this because:

• I no longer want to dump xxd or hexdump output to a pager, like less;
• I was worried about portability;

Usage

For additional help, use the --help command-line option.

Interactive Mode (default mode)

This mode allows you to navigate the view freely for files and block devices.

It replaces the need to pipe the output for xxd(1) or hexdump(1) into a pager, like less(1).

There are four sub-modes for the interactive session:

• Insert (--insert);
  • In insert mode, new data is inserted at the positon of the caret, pushing old data forward.
  • This is the default editing mode.
• Overwrite (--overwrite);
  • In overwrite mode, new data overwrites old data at the positon of the caret.
• Read-only (-R|--readonly);
  • Editing data is disallowed in this mode, but cursor nagivation remains.
• And view (view).
  • This emulates the old viewing navigation mechanic by disabling the cursor.
  • This is closest to using less(1).

Screen

The interactive session screen consists of three parts:

• Offset bar at the top;
  • The single element offset is shown here.
  • The menu prompt will appear here.
• Data and text representation;
  • The base offset, binary data, and text representation is shown here.
• And a status bar.
  • By default, these are:
    • Editing mode (insert);
    • Data mode (hex)
    • Text mode (ascii);
    • Binary size of view;
    • Absolute cursor position;
    • And position percentage within file or device.

Menu

The menu system can be invoked using : (ala vim). Enter is the old way to invoke it.

Some commands require / (forward search) or ? (backward search) to be invoked.

To set a setting, like a character set (charset) or offset type (offset), use set <option> <value>. For example: set columns auto

Dump

The dump mode replaces the need for xxd(1) and hexdump(1).

Most formatting settings can be used for this mode.

Platforms

• Windows XP (x86-omf builds)
• Windows Vista+ (x86-mscoff and x86-64)
• Linux (glibc and musl)
