## Usage

Add the `textwrap-macros` crate to the `Cargo.toml` manifest:

```toml
[dependencies]
textwrap-macros = "0.2"
```

Then either use the macros using the old-style `#[macro_use]` or import them as
any other crate member:
```rust
use textwrap_macros::dedent;

const poem: &str = dedent!(r#"
      When we two parted
      In silence and tears,
      Half broken-hearted
      To sever for years,
      Pale grew thy cheek and cold,
      Colder thy kiss;
      Truly that hour foretold
      Sorrow to this.
"#);
```

Macros usage with small examples can be found on
[`docs.rs`](https://docs.rs/textwrap-macros). The following functions have been
ported into macros:

- [x] [`dedent`](https://docs.rs/textwrap-macros/latest/textwrap_macros/macro.dedent.html)
- [x] [`fill`](https://docs.rs/textwrap-macros/latest/textwrap_macros/macro.fill.html)
- [x] [`indent`](https://docs.rs/textwrap-macros/latest/textwrap_macros/macro.indent.html)
- [x] [`wrap`](https://docs.rs/textwrap-macros/latest/textwrap_macros/macro.wrap.html)
- [ ] [`unfill`](https://docs.rs/textwrap/latest/textwrap/fn.unfill.html)
- [ ] [`refill`](https://docs.rs/textwrap/latest/textwrap/fn.refill.html)
- [ ] [`wrap_columns`](https://docs.rs/textwrap/latest/textwrap/fn.wrap_columns.html)

Check out the [documentation of the original library](https://docs.rs/textwrap/)
for more information about the behaviour of each of the wrapped functions.
