# Classes

class HTML a where

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.

Minimal complete definition

toHtml

Methods

toHtml :: a -> Html

toHtmlFromList :: [a] -> Html

Instances

HTML Char |
HTML Html |
HTML HotLink |
HTML HtmlTable |
HTML HtmlTree |
HTML a => HTML [a] |
HTML a => HTML (Maybe a) |

class ADDATTRS a where

Methods

(!) :: a -> [HtmlAttr] -> a infixl 8

Instances

ADDATTRS Html |
ADDATTRS HotLink |
ADDATTRS b => ADDATTRS (a -> b) |

class CHANGEATTRS a where

CHANGEATTRS is a more expressive alternative to ADDATTRS

Methods

changeAttrs :: a -> ([HtmlAttr] -> [HtmlAttr]) -> a

Instances

CHANGEATTRS Html |
CHANGEATTRS b => CHANGEATTRS (a -> b) |

# Primitives and basic combinators

(<<) infixr 7

Arguments

:: HTML a |
=> (Html -> b) | Parent
-> a | Child
-> b |

Put something inside an HTML element.

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

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

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

noHtml :: Html

An empty piece of HTML.

isNoHtml :: Html -> Bool

Checks whether the given piece of HTML is empty.

tag

Arguments

:: String | Element name
-> Html | Element contents
-> Html |

Constructs an element with a custom name.

itag :: String -> Html

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

htmlAttrPair :: HtmlAttr -> (String, String)

emptyAttr :: String -> HtmlAttr

intAttr :: String -> Int -> HtmlAttr

strAttr :: String -> String -> HtmlAttr

htmlAttr :: String -> Html -> HtmlAttr

primHtml :: String -> Html

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

stringToHtmlString :: String -> String

Processing Strings into Html friendly things.

docType :: String

The `DOCTYPE` for XHTML 1.0 Strict.

# Rendering

showHtml :: HTML html => html -> String

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

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

renderHtmlWithLanguage

Arguments

:: HTML html |
=> String | The code of the "dominant" language of the webpage.
-> html | All the `Html`, including a header.
-> String |

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

prettyHtml :: HTML html => html -> String

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

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

renderHtmlFragment :: HTML html => html -> String

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

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`.

# Converting strings to HTML

stringToHtml :: String -> Html

Convert a `String` to `Html`, converting characters that need to be escaped to HTML entities.

lineToHtml :: String -> Html

This converts a string, but keeps spaces as non-line-breakable.

linesToHtml :: [String] -> Html

This converts a string, but keeps spaces as non-line-breakable, and adds line breaks between each of the strings in the input list.

# Html abbreviations

primHtmlChar :: String -> Html

copyright :: Html

Copyright sign.

spaceHtml :: Html

Non-breaking space.

bullet :: Html

p :: Html -> Html

Same as `paragraph`.
