README
A modern alternative to `xxd` and `hexdump`
## Quick install
requirements: Go 1.20+ (it may build with earlier versions as well but I have not tested them) and git
```sh
go install github.com/sweetbbak/hexxy@latest
```
On ArchLinux ([hexxy-git](https://aur.archlinux.org/packages/hexxy-git)), e.g.:
```
pikaur -S hexxy-git
```
## Example usage
```sh
# normal usage
hexxy /path/to/file.bin
# output without color
hexxy --no-color /path/to/file.bin
# read from stdin
cat mybinary | hexxy
# display plain output
hexxy -p file.bin
# Include a binary as a C variable
hexxy -i input-file > output.c
# Use plain non-formatted output
hexxy -p input-file
# crunch empty lines with a '*' and use uppercase HEX
hexxy -a --upper input-file
# Reverse plain non-formatted output (reverse plain)
hexxy -rp input-file
# Show output with a space in between N groups of bytes
hexxy -g1 input-file ... -> outputs: 00000000: 0f 1a ff ff 00 aa
# display offset in Decimal format
hexxy -td file.bin
# display offset in Octal format
hexxy -to file.bin
```
## Performance
`zk` is a 17mb binary
```sh
xxd -i ~/bin/zk &> /dev/null 0.66s user 0.02s system 99% cpu 0.677 total
hexxy -i ~/bin/zk &> /dev/null 0.16s user 0.01s system 98% cpu 0.165 total
```
```sh
# plain XXD
xxd ~/bin/zk &> /dev/null 0.12s user 0.01s system 99% cpu 0.126 total
# hexxy without color
hexxy -N ~/bin/zk &> /dev/null 0.21s user 0.01s system 100% cpu 0.223 total
# hexxy with color
hexxy ~/bin/zk &> /dev/null 0.37s user 0.01s system 99% cpu 0.383 total
```
