dbgfmt

CI crates.io License: MIT OR Apache-2.0

A zero-dependency Rust library and CLI tool that pretty-prints Rust Debug trait output with proper indentation and newlines.

Example

Input:

Foo { bar: 1, baz: Vec { items: [1, 2, 3] }, name: "hello" }

Output:

Foo {
    bar: 1,
    baz: Vec {
        items: [
            1,
            2,
            3,
        ],
    },
    name: "hello",
}

As a Library

Add to your Cargo.toml:

[dependencies]
dbgfmt = "0.1"

Use in your code:

use dbgfmt::format_debug;

let input = format!("{:?}", my_struct);
let pretty = format_debug(&input, 4);
println!("{pretty}");

As a CLI

Usage

# Pass as argument
dbgfmt 'Foo { bar: 1, baz: [2, 3] }'

# Pipe from stdin
echo 'Foo { bar: 1, baz: [2, 3] }' | dbgfmt

# Format dbg!() macro output (prefix is preserved)
echo '[src/main.rs:5:5] config = Config { host: "localhost", port: 8080 }' | dbgfmt

# Multiple values (separate lines or same line)
