binary reader

A simple binary file reader that dumps the output to stdout


cargo install bred


Usage: bred [OPTIONS] [FILE]

  [FILE]  The file to read or stdin if not provided

  -l, --length <CHARACTERS>  Number of characters to print [default for hex: 8] [default: 64]
  -c, --chunk <BYTES>        Chunk size (faster but more memory usage) [default: 4096]
  -x, --hex                  Print in hex
  -G, --color                Print in color
  -s, --space                Explicitly display space as placeholder: (_)
  -b, --binary               Print in binary
  -h, --help                 Print help information
  -V, --version              Print version information

To use, input a file (or stdin is used), and add any desired options.
The --length option changes how many characters to print (not including any formatting like offsets and borders).
The --chunk option changes how large the buffer array should be; the bigger it is, the faster but uses more memory.
The --hex option simply prints the input in hexadecimal.
The --color option uses colors to differentiate between letters (\0 are gray, others indicate how large the character code is, and orange is non-ascii characters). Note, make sure you use a terminal emulator that supports ANSI 256-color mode.
The --space option replaces all the spaces (0x20) with a green-colored _. This also affects the hex output.
The --binary option prints the input in binary
