# dedent
A Rust procedural macro for stripping whitespace from multi-line string literals while preserving relative indentation.
## Features
- 📐 Preserves relative indentation between lines
- 🧹 Trims leading and trailing empty lines
## Usage
```rust
use dedent::dedent;
fn main() {
// Basic usage
let code = dedent!(r#"
fn main() {
println!("Hello, world!");
}
"#);
println!("{}", code);
// Output:
// fn main() {
// println!("Hello, world!");
// }
// Works with varying indentation
let text = dedent!(r#"
First line
Indented line
More indented
Back to start
"#);
println!("{}", text);
// Output:
// First line
// Indented line
// More indented
// Back to start
}
```
## How It Works
The `dedent!` macro:
1. Takes a string literal as input
1. Splits it into lines
1. Calculates the minimum indentation level across all non-empty lines
1. Removes that amount of whitespace from the start of each line
1. Removes leading and trailing empty lines
1. Preserves relative indentation between lines
