/// # `hiccup!`:
/// * The main objective of this lib is to prevent unclosed html tags.
/// This macro is inspired by Clojures [hiccup](https://github.com/weavejester/hiccup)
///
/// ## Basic usage:
///
/// The macro `hiccup! receives a mutable string as the first argument and mutates the string to emit the HTML.
/// The order of the elements is:
/// 1. `tag` as the first element.
/// 2. Optional attribute inside the tag should follow the tag name as `{attribute1=>"value1 value2 ... valuen", attr=>"value"}`. Also, the attributes should be inside `{...}` and separate each key value pair by `,`.
/// The element should be written as `key=>"value"`, where key is a symbol, followed by an arrow (`=>`), and then the value as a string `"value"`.
/// 3. After (Optional) the tag name or the attributes `{...}` you could include `[...]` that can have other tags, such as `p["text"]` or regular string values.
/// 4. Inside the `[...]` you also can substitute your string for some simple rust code inside a `(...)`. This can bem something like `p[format!("{:?}", 3 + 4)]` or `div[(x)]` where x was defined in the outside.
///
/// ### Differences between Clojure and Rust Hiccup:
/// * [Clojure](https://github.com/weavejester/hiccup/wiki/Syntax): `[:a {:href "http://github.com"} "GitHub"]`
/// * Rust: `a{href=>"http://github.com"}["GitHub"]`
///
/// ### Syntax with code inside:
/// * `a{href=>"http://github.com"}[(format!("{:?}", 3 + 5))]`
/// * `p[(x)]`, where `x` can be another `html` or simply a value;
///
/// ## Example
///
/// ### Basic syntax
/// ```rust
/// use hiccup::hiccup;
///
/// fn main() {
/// let mut html = String::new();
///
/// let _ = hiccup!(&mut html,
/// html[
/// head[meta{name=>"author", content=>"Julia Naomi"}
/// title["Hiccup guide"]]
/// body{class=>"amazing hiccup guide"}[
/// h1{font=>"bold", color=>"red"}["Hiccup is the best!"]
/// p["please lookup clojure's hiccup for better ideas on this macro"]]
/// ]);
///
/// assert_eq!(html,"<html><head><meta name=\"author\" content=\"Julia Naomi\"/>\
/// <title>Hiccup guide</title></head><body class=\"amazing hiccup guide\">\
/// <h1 font=\"bold\" color=\"red\">Hiccup is the best!</h1>\
/// <p>please lookup clojure\'s hiccup for better ideas on this macro</p></body></html>");
/// }
/// ```
///
/// ### With remote code execution
/// ```rust
/// use hiccup::hiccup;
///
/// fn main() {
/// let mut html_inner = String::new();
/// let mut html_outer = String::new();
/// let x = "inner my str";
/// let y = "my str2";
/// let z = "my str3";
///
/// let _ = hiccup!(&mut html_inner,
/// div[
/// div{hello=>"inner world"}[(x)]
/// ]
/// );
///
/// let _ = hiccup!(&mut html_outer,
/// html[
/// body{class=>"amazing hiccup guide"}[
/// p["please lookup clojure's hiccup for better ideas on this macro"]
/// div[
/// div{hello=>"world"}[(html_inner)]
/// div[(y.to_owned() + " " + z)]
/// p["bye"]
/// ]
/// ]
/// ]);
///
/// assert_eq!(html_outer,"<html><body class=\"amazing hiccup guide\">\
/// <p>please lookup clojure\'s hiccup for better ideas on this macro</p>\
/// <div><div hello=\"world\"><div><div hello=\"inner world\">inner my str</div></div></div>\
/// <div>my str2 my str3</div><p>bye</p></div></body></html>");
/// }
/// ```
/// ## FAQs
/// 1. Is it possible tu use this lib as an XML templating?
/// > Yes, I added a more generic XML case to the tests recently
///
/// ```rust
/// use hiccup::hiccup;
///
/// fn main() {
/// let mut out = String::new();
///
/// let _ = hiccup!(&mut out,
/// xml{metas=>"I forgot them all", version=>"any version"}[
/// family[name{name=>"Rubiechiov", origin=>"Kazakhstan"}]
/// members{class=>"close family"}[
/// member{age=>"oldest", color=>"yellow"}["some name"]
/// member{age=>"mid-age", color=>"yellow"}["some other name"]
/// member{age=>"yougest", color=>"brown"}["Julia"]]
/// ]);
///
/// assert_eq!(out,"<xml metas=\"I forgot them all\" version=\"any version\"><family>\
/// <name name=\"Rubiechiov\" origin=\"Kazakhstan\"/></family><members class=\"close family\">\
/// <member age=\"oldest\" color=\"yellow\">some name</member>\
/// <member age=\"mid-age\" color=\"yellow\">some other name</member>\
/// <member age=\"yougest\" color=\"brown\">Julia</member></members></xml>");
/// }
/// ```
