xxd-rs crates-io

A rust based reimplementation of Juergen Weigert's hexdump utility, xxd.

Mission statement

This project was created to learn rust, therefore there is no perf If you wanna use the project or contribute feel free, but please take note of the goal(s) and non goals so you won't waste your time or get frustrated.

Goals

  1. Learn rust

  2. Provide a rust based replacement for xxd

  3. Strive towards a clean rust code base

    • rustfmt
    • Add/refactor towards common rust idioms

  4. Usability

    • Provide user friendly defaults
    • Provide clear and well documented command line tools

  5. Continuously improve the code base

Non Goals

What this Project isn't about

  1. Implement the fastest dump utility out there
    • If you are looking for a performant implementation of xxd checkout go-xxd

Usage

USAGE:
    xxd-rs [OPTIONS] [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -l, --length <length>          Amount of bytes which shall be read
    -o, --output-file <outfile>    File to which the output will be written (default: stdout)
    -s, --seek <seek>              Offset in the file where to start reading

SUBCOMMANDS:
    dump        Dumps an input file in the appropriate output format
    generate    Generates a source file containing the specified file as array
    help        Prints this message or the help of the given subcommand(s)

Examples

  1. Dump file
user@host:~$ xxd-rs dump file.txt
  1. Dump file with 16 bit word size
user@host:~$ xxd-rs generate -g 2 file.txt
  1. Dump 1024 bytes of file file starting at offset 128
user@host:~$ xxd-rs dump -s 128 -l 1024 file.txt
  1. Generate cpp header file containing file in an cpp array
user@host:~$ xxd-rs generate -t cpp file.txt

Migration/Compatibility

Be aware that the output formats (especially the default) of hexdump, xxd, od, and xxd-rs differ.

  1. Dump file
    1. xxd
    user@host:~$ xxd file
    1. od
    user@host:~$ od file
    1. hexdump
    user@host:~$ xxd-rs dump file
    1. xxd-rs
    user@host:~$ xxd-rs dump file
