kex

Streamed hex dumping library.

Features

• Streamed I/O.
• Works with output, implementing Write trait.
• Customizable formatting
• Row deduplication
• Very fast

Demo

Binary

Short guide

# Example
kex -a h8 -b h -g 8/2 -s 40 -n 10 file1 file2 file3 ...

Will print specified files sequentally as single stream. If no files specified, program will expect input from stdin

Arguments

-a <format>[min_width] - the address format. (Defaults to h8)

<format> - address representation. Accepts values:

• h - hexadecimal
• b - binary
• d - decimal
• o - octal

<min_width> - minimum width of displayed address. All, but decimal will be padded by zeros. Decimal padded with empty spaces

-b <format> - format of the raw data (defaults to h)

<format> - byte representation. Accepts values:

• h - hexadecimal
• b - binary
• d - decimal
• o - octal
• c - ASCII characters. (Excludes characters/third column)
• C - Caret notation + ASCII characters. (Excludes characters/third column)

-g group_size[/number_of_groups] (defaults to 8/2)

or

-g bytes_per_row

-s num_of_bytes_to_skip (defaults to 0)

-n num_of_bytes_to_rear (if not specified, data will be read until EOF)

Library

Examples

One of examples

use kex::*;
use std::fs::File;
use std::io::stdout;
use std::io::{Read, Write};

fn main() {

    let mut buf = [0u8; 4096];

    // let stdin = std::io::stdin();
    // let mut handle = stdin.lock();

    let config = Config::new(
        Some(AddressFormatter::new(AddressStyle::Hex(16), Default::default())),
        ByteFormatter::new(Groupping::RepeatingGroup(Group::new(4, " "), 4), false, Default::default()),
        Some(CharFormatter::default()),
        true,
    );
    let mut printer = Printer::new(stdout(), 0, config);
    
    let mut file = File::open("/bin/cat").expect("Can't open file");

    while let Ok(size) = file.read(&mut buf) {
        if size == 0 {
            break;
        }
        assert!(printer.write_all(&mut buf[..size]).is_ok());
    }

    printer.finish();
}
