libschnauzer

Schnauzer is both library and tool for parsing mach-o files

Features

• Zero copy. Does not loads whole binary into memory. Uses iterators to list potentially large amount of items
• Endian aware
• Implements derive macro for automatic field enumeration, that, for example, very convenient for printing arbitary load commands. There even no need to write large match blocks for any type of load command
• Prints file structure in color for better user experience

Installation

shell cargo install schnauzer

Example output

Put something like in your console:

shell schnauzer /bin/cat

And you get:

Examples

Simple debug print

```rust use schnauzer::ObjectType; use schnauzer::Parser; use std::path::Path;

fn main() { let mut args = std::env::args(); let execname = args.next();

let path = match args.next() {
    Some(s) => s,
    None => {
        eprintln!("Not enough arguments. Provide a valid path to binary");
        std::process::exit(1);
    }
};
let path = Path::new(&path);

let parser = match Parser::build(path) {
    Ok(b) => b,
    Err(e) => {
        eprintln!("Could not create parser at '{:?}': {e}", path);
        std::process::exit(1);
    }
};

let object = match parser.parse() {
    Ok(o) => o,
    Err(e) => {
        eprintln!("Error while parsing: {:#?}", e);
        std::process::exit(1);
    }
};

handle_object(object);

}

fn handle_object(obj: ObjectType) { println!("Object"); println!("{:#?}", obj); } ```

Using AutoEnumFields derive (code taken from src/main.rs)

rust let h = macho.header(); for field in h.all_fields() { out_dashed_field(field.name, field.value, level); }
