Parses a CSS stylesheet See StyleSheet & parseForURL.

Documentation

parse :: StyleSheet s => s -> Text -> s

Parse a CSS stylesheet

parse' :: StyleSheet t => t -> [Token] -> t

Parse a tokenized (via `css-syntax`) CSS stylesheet

parseForURL :: StyleSheet s => s -> URI -> Text -> s

Parse a CSS stylesheet, resolving all URLs to absolute form.

class StyleSheet s where

Describes how to store, and to some extent parse, CSS stylesheets. These methods are used to construct the results from parse, etc.

Minimal complete definition

addRule

Methods

setPriority :: Int -> s -> s

Sets the stylesheet priority (useragent vs user vs author), optional. Favor setPriorities for richer API.

setPriorities :: [Int] -> s -> s

Sets the multi-layered stylesheet priority (for the sake of @layer rules), optional.

addRule :: s -> StyleRule -> s

Stores a parsed selector+properties rule.

addAtRule :: s -> Text -> [Token] -> (s, [Token])

Stores and parses an identified at-rule.

Instances

StyleSheet ()

In case an indirect caller doesn't actually want to use Haskell Stylist.

Defined in Stylist.Parse

Methods

setPriority :: Int -> () -> ()

setPriorities :: [Int] -> () -> ()

addRule :: () -> StyleRule -> ()

addAtRule :: () -> Text -> [Token] -> ((), [Token])

StyleSheet TrivialStyleSheet

addRule :: TrivialStyleSheet -> StyleRule -> TrivialStyleSheet

addAtRule :: TrivialStyleSheet -> Text -> [Token] -> (TrivialStyleSheet, [Token])

skipAtRule :: [Token] -> [Token]

Returns tokens after an at-rule, as per scanAtRule.

scanAtRule :: Parser [Token]

Returns tokens before & after an at-rule value, terminated after a curly-bracketed block or a semicolon.

scanBlock :: Parser [Token]

Returns tokens until the next unbalanced closing brace.

skipSpace :: [Token] -> [Token]

Removes preceding Whitespace tokens.

data StyleRule

The properties to set for elements matching the given selector.

Parse "key: value;"... property values, as per the HTML "style" property.

scanValue :: Parser [Token]

Returns tokens before & after a semicolon.
