Data types

data Html Source

data HtmlAttr Source

Attributes with name and value.

Classes

class HTML a where Source

HTML is the class of things that can be validly put inside an HTML tag. So this can be one or more Html elements, or a String, for example.

class ADDATTRS a where Source

class CHANGEATTRS a where Source

CHANGEATTRS is a more expressive alternative to ADDATTRS

Primitives and basic combinators

(<<) infixr 7 Source

Put something inside an HTML element.

concatHtml :: HTML a => [a] -> Html Source

(+++) :: (HTML a, HTML b) => a -> b -> Html infixr 2 Source

Create a piece of HTML which is the concatenation of two things which can be made into HTML.

noHtml :: Html Source

An empty piece of HTML.

isNoHtml :: Html -> Bool Source

Checks whether the given piece of HTML is empty.

tag Source

Constructs an element with a custom name.

itag :: String -> Html Source

Constructs an element with a custom name, and without any children.

htmlAttrPair :: HtmlAttr -> (String, String) Source

emptyAttr :: String -> HtmlAttr Source

intAttr :: String -> Int -> HtmlAttr Source

strAttr :: String -> String -> HtmlAttr Source

htmlAttr :: String -> Html -> HtmlAttr Source

primHtml :: String -> Html Source

This is not processed for special chars. use stringToHtml or lineToHtml instead, for user strings, because they understand special chars, like <.

Rendering

showHtml :: HTML html => html -> String Source

Output the HTML without adding newlines or spaces within the markup. This should be the most time and space efficient way to render HTML, though the ouput is quite unreadable.

renderHtml :: HTML html => html -> String Source

Outputs indented HTML. Because space matters in HTML, the output is quite messy.

prettyHtml :: HTML html => html -> String Source

Outputs indented HTML, with indentation inside elements. This can change the meaning of the HTML document, and is mostly useful for debugging the HTML output. The implementation is inefficient, and you are normally better off using showHtml or renderHtml.

showHtmlFragment :: HTML html => html -> String Source

Render a piece of HTML without adding a DOCTYPE declaration or root element. Does not add any extra whitespace.

renderHtmlFragment :: HTML html => html -> String Source

Render a piece of indented HTML without adding a DOCTYPE declaration or root element. Only adds whitespace where it does not change the meaning of the document.

prettyHtmlFragment :: HTML html => html -> String Source

Render a piece of indented HTML without adding a DOCTYPE declaration or a root element. The indentation is done inside elements. This can change the meaning of the HTML document, and is mostly useful for debugging the HTML output. The implementation is inefficient, and you are normally better off using showHtmlFragment or renderHtmlFragment.
