dbg-pls

A Debug-like trait for rust that outputs properly formatted code

Usage in libraries

Add to your Cargo.toml

dbg-pls = "*"

Add to your types

#[derive(dbg_pls::DebugPls)]

Usage for applications

Add to your Cargo.toml

dbg-pls = { version = "0.1", features = ["pretty"] }

And print using debug, eg

println!("{}", debug(&value));

Features

• derive - enables the #[derive(DebugPls)] derive (default)
• pretty - enables the debug function for pretty printing
• colors - enables the color function for syntax highlighted printing

Example

use dbg_pls::{debug, DebugPls};

#[derive(DebugPls, Copy, Clone)]
pub struct Demo {
    foo: i32,
    bar: &'static str,
}

let mut val = [Demo { foo: 5, bar: "hello" }; 10];
val[6].bar = "Hello, world! I am a very long string";

println!("{}", debug(&val));

Outputs

[
    Demo { foo: 5, bar: "hello" },
    Demo { foo: 5, bar: "hello" },
    Demo { foo: 5, bar: "hello" },
    Demo { foo: 5, bar: "hello" },
    Demo { foo: 5, bar: "hello" },
    Demo { foo: 5, bar: "hello" },
    Demo {
        foo: 5,
        bar: "Hello, world! I am a very long string",
    },
    Demo { foo: 5, bar: "hello" },
    Demo { foo: 5, bar: "hello" },
    Demo { foo: 5, bar: "hello" },
]

Example (highlighting)

use dbg_pls::{color, DebugPls};

#[derive(DebugPls, Copy, Clone)]
pub struct Demo {
    foo: i32,
    bar: &'static str,
}

let mut val = [Demo { foo: 5, bar: "hello" }; 10];
val[6].bar = "Hello, world! I am a very long string";

println!("{}", color(&val));

Outputs:
