# Literify

Stringifies (and concats) literal within the passed token stream inside `~()` group. It is also possible to concaternate with other strings inside the group.

This can be useful when you need to stringify a literal for a use in macro,
but macro expects a literal token tree, so usage of `stringify!` is not possible.

## Example
```rust
use logos::Logos;

literify::literify! {
    #[derive(Debug, PartialEq, Logos)]
    enum Token {
        #[token(~("amog" u s))]
        Amogus,
    }
}

assert_eq!(
    Token::lexer("amogus").next(),
    Some(Ok(Token::Amogus)),
);
```
