Description

Core types of taggy.

Synopsis

Tag type

data Tag Source

A Tag can be one of the following types of tags:

  • an opening tag that has a name, a list of attributes, and whether it is a self-closing tag or not * a closing tag with the name of the tag * some raw Text * an HTML comment tag * a script.../script tag * a style.../style tag

The latter two are useful to be considered separately in the parser and also lets you collect these bits quite easily.

Constructors

TagOpen !Text [Attribute] !Bool 
TagClose !Text 
TagText !Text 
TagComment !Text 
TagScript !Tag !Text !Tag 
TagStyle !Tag !Text !Tag 

Instances

tname :: Tag -> TextSource

Name of a Tag. 

 tname (TagClose "a") == "a"

isTagOpen :: Tag -> BoolSource

Is this Tag an opening tag?

isTagClose :: Tag -> BoolSource

Is this Tag a closing tag?

isTagText :: Tag -> BoolSource

Is this Tag just some flat text?

isTagComment :: Tag -> BoolSource

Is this Tag an HTML comment tag?

isTagScript :: Tag -> BoolSource

Is this Tag a script.../script tag?

isTagStyle :: Tag -> BoolSource

Is this Tag a style.../style tag?

tagsNamed :: Text -> [Tag] -> [Tag]Source

Get all the (opening) tags with the given name

Attributes

data Attribute Source

An attribute is just an attribute name and an attribute value.

Constructors

Attribute !Text !Text 

Instances

attrs :: Tag -> [Attribute]Source

Get the attributes of a Tag.

attrKey :: Attribute -> TextSource

Get the name of an Attribute.

attrValue :: Attribute -> TextSource

Get the value of an Attribute.

A small difference list implementation

data L a Source

emptyL :: L aSource

appL :: L a -> L a -> L aSource

insertL :: a -> L a -> L aSource

singletonL :: a -> L aSource

toListL :: L a -> [a]Source
