This crate contains procedural macros for removing multiple consecutive whitespaces from a

given string literal, replacing them with a single space.

## Example

The example below uses an optional quotation character to keep quoted text ranges un-merged, as well as

an optional escape character to ensure that quotation character literals are kept as-is.

```rust

use merge_whitespace::merge_whitespace;

const QUERY: &str = merge_whitespace!(r#"

     query {

       users (limit: 1, filter: "bought a 12\" vinyl

                                 named \"spaces  in  space \"") {

         id

         name

         todos(order_by: {created_at: desc}, limit: 5) {

           id

           title

         }

       }

     }

     "#,

     quote_char = '"',

     escape_char = '\\');

#[test]

fn test() {

    assert_eq!(QUERY, r#"query { users (limit: 1, filter: "bought a 12\" vinyl

                                 named \"spaces  in  space \"") { id name todos(order_by: {created_at: desc}, limit: 5) { id title } } }"#);

}

```

Alternatively, the `merge_whitespace_utils::merge_whitespace` function can be used to process variable input.
