hex (hx)

Futuristic take on hexdump.

hx accepts a file path as input and outputs a hexadecimal colorized view to stdout.

hx also accepts stdin as input.

examples

lower hex format -fx

$ hx src/main.rs

binary hex format -fb

$ hx -fb -c4 src/main.rs

octal hex format -fo

$ hx -fo -c8 src/main.rs

install

crates.io install

If cargo is already installed, simply:

cargo install hx

source install

From within the hx source code directory, simply execute:

make install

This will run the following cargo commands:

cargo build --release
cargo test --verbose --all -- --nocapture
cargo install --path .

Which will compile the release version, run tests and install release binary to <USERDIR>/.cargo/bin/hx.

If <USERDIR>/.cargo/bin is part of the PATH environment variable, hx should be able to be executed anywhere in the shell.

debian install

curl -sLO https://github.com/sitkevij/hex/releases/download/v0.4.0/hx_0.4.0_amd64.deb && dpkg -i hx_0.4.0_amd64.deb

docker run

cat README.md | docker run -i sitkevij/hx:latest

features

output arrays in rust, c, golang, python, kotlin, or java

hx has a feature which can output the input file bytes as source code arrays.

For example:

rust array: -ar

$ hx -ar -c8 tests/files/tiny.txt
let ARRAY: [u8; 3] = [
    0x69, 0x6c, 0x0a
];

c array: -ac

$ hx -ac -c8 tests/files/tiny.txt
unsigned char ARRAY[3] = {
    0x69, 0x6c, 0x0a
};

golang array: -ag

$ hx -ag -c8 tests/files/tiny.txt
a := [3]byte{
    0x69, 0x6c, 0x0a,
}

python array: -ap

$ hx -ap -c8 tests/files/tiny.txt
a = [
    0x69, 0x6c, 0x0a
]

kotlin array: -ak

$ hx -ak -c8 tests/files/tiny.txt
val a = byteArrayOf(
    0x69, 0x6c, 0x0a
)

java array: -aj

$ hx -aj -c8 tests/files/tiny.txt
byte[] a = new byte[]{
    0x69, 0x6c, 0x0a
};

NO_COLOR support

hx will honor the NO_COLOR environment variable. If set, no color will be output to the terminal.
