pure_lines

A tool that beautify multiple lines. * Trim first line if empty * Trim min indent

Problem

What you need str: rust hello world You had to do: rust let s = "hello world"; println!("{}",s); Now you can: rust let s = " hello world"; println!("{}",pure_lines::pure(s));

Example

Basic Example

``` rust use pure_lines;

fn main(){ let a = " hello world"; println!("=============="); println!("before:"); println!("{}",&a); println!("=============="); let s = pure_lines::pure(a); println!("after:"); println!("{}",s); println!("==============");

// Output:
// ==============
// before:
//
//     hello
//     world
// ==============
// after:
// hello
// world
// ==============

} ```

Example with prefix

``` rust use pure_lines;

fn main(){ let a = " hello world"; println!("=============="); println!("before:"); println!("{}",&a); println!("=============="); let s = purelines::purewith(a,"> "); println!("after:"); println!("{}",s); println!("==============");

// Output:
// ==============
// before:
//
//     hello
//     world
// ==============
// after:
// > hello
// > world
// ==============

} ```

Advance

If you want your code more faster, using the quick feature. quick feature trim indent based on the first line which is not empty.

⚠Note: make sure the after lines indent must bigger than the first，or you will lose some string.

your Cargo.toml could look like this: toml [dependencies] pure_lines = { version = "0.2.0", features = ["quick"] }
