shapely-pretty

A pretty-printing library for types implementing the Shapely trait, providing colorful and well-formatted output.

Features

• Pretty-print any type implementing the Shapely trait
• Colorful output with ANSI escape codes
• Unique colors for different scalar types based on their Shape hash
• Customizable indentation and formatting
• Dimmed colors for punctuation
• Simple abstraction over ANSI escape codes

Example

use shapely::Shapely;
use shapely_pretty::PrettyPrinter;

#[derive(Debug, Shapely)]
struct Person {
    name: String,
    age: u32,
    address: Address,
}

#[derive(Debug, Shapely)]
struct Address {
    street: String,
    city: String,
    country: String,
}

let person = Person {
    name: "Alice".to_string(),
    age: 30,
    address: Address {
        street: "123 Main St".to_string(),
        city: "Wonderland".to_string(),
        country: "Imagination".to_string(),
    },
};

// Print with default settings
PrettyPrinter::new().print(&person);

// Customize the printer
PrettyPrinter::new()
    .with_indent_size(4)
    .with_max_depth(3)
    .print(&person);
