# 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 = pure_lines::pure_with(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"] }
```
