## Features

- Capture groups

## Dependencies

```toml
[dependencies]
regex = "1"
regexm = "0.2"
```

## Usage

```rust
fn main() {
    let text1 = "2020-01-01";
    regexm::regexm!(match text1 {
        r"^\d{4}$" => println!("yyyy"),
        r"^\d{4}-\d{2}$" => println!("yyyy-mm"),
        // block
        r"^\d{4}-\d{2}-\d{2}$" => {
            let yyyy_mm_dd = "yyyy-mm-dd";
            println!("{}", yyyy_mm_dd);
        }
        _ => println!("default"),
    });
}
```

Output:

```sh
yyyy-mm-dd
```

```rust
fn main() {
    let text2 = "foo";
    let foo = regexm::regexm!(match text2 {
        r"^\d{4}-\d{2}-\d{2}$" => "yyyy-mm-dd",
        r"^\d{4}-\d{2}$" => "yyyy-mm",
        // block
        r"^\d{4}-\d{2}-\d{2}$" => {
            let yyyy_mm_dd = "yyyy-mm-dd";
            yyyy_mm_dd
        }
        _ => "default",
    });
    println!("{}", foo);
}
```

Output:

```sh
default
```

```rust
fn main() {
    let text1 = "2020-01-02";
    regexm::regexm!(match text1 {
        // capture groups
        captures(r"^(\d{4})-(\d{2})-(\d{2})$") => |caps| println!(
            "year: {}, month: {}, day: {}",
            caps.get(1).map_or("", |m| m.as_str()),
            caps.get(2).map_or("", |m| m.as_str()),
            caps.get(3).map_or("", |m| m.as_str())
        ),
        _ => println!("default"),
    });
}
```

Output:

```sh
2020
01
02
```
