Category Group Element

---

The Category Group Element groups matchers into named categories. All descendents of a category group will inherit this element's category unless they explicitly define their own category attribute.

Syntax

<category-group category="WHITESPACE">
...
</category-group>

Class

com.aptana.ide.lexer.matcher.model.CategoryGroupElement

Children

Any IMatcher class

Attributes

Name	Description	Type	Default	Required
category	Sets the category to which all descendants will be associated. Descendents may override this value by defining their own category attributes. The active category name is used when adding tokens to the MatcherTokenList for IMatcher elements that define a type attribute.	String	null	yes

Lexer Element

---

The Lexer Element is the XML root element used when defining a language's lexer. This element includes attributes for defining the language's MIME type and the associated enumeration used to cross-reference type attribute values to integers.

The Lexer Element (and all descendants) must be in the http://www.aptana.com/2007/lexer/1.2 namespace.

Syntax

<lexer
    xmlns="http://www.aptana.com/2007/lexer/1.2"
    language="text/css"
    type-enumeration="com.aptana.ide.editor.css.lexing.CSSTokenTypes">
...
</lexer>

Class

com.aptana.ide.lexer.matcher.model.LexerElement

Children

<token-group/>
<bundle/>
<package/>

Attributes

Name	Description	Type	Default	Required
language	Sets the MIME type for this lexer's language	String	null	yes
category-enumeration	The fully-qualified Java class to be used to lookup integer values for type category values	String	null	no
type-enumeration	The fully-qualified Java class to be used to lookup integer values for type attribute values	String	null	no

Token Group Element

---

The Token Group Element groups matchers into named groups. All children of a token group are added to the resulting MatcherTokenList created by the Lexer Element.

Syntax

<token-group group="default">
...
</token-group>

Class

com.aptana.ide.lexer.matcher.model.TokenGroupElement

Children

<category-group/>
Any IMatcher class

Attributes

Name	Description	Type	Default	Required
group	Sets the group to which this element's children will be associated in the MatcherTokenList	String	null	yes

Use Element

---

The Use Element allows for the injection of matched text from a previously successful match. This allows for dynamic defintion of a matcher's content at runtime. Currently, only StringMatchers and CharacterMatchers allow use elements as children.

Syntax

<and category="LITERAL" type="STRING">
  <character-class name="quote">'"</character-class>
  <to-delimiter>
    <string>
      <use name="quote"/>
    </string>
  </to-delimiter>
</and>

Class

com.aptana.ide.lexer.matcher.model.UseElement

Children

none

Attributes

Name	Description	Type	Default	Required
name	Specifies a name defined in another matcher's name attribute. The text from that matcher's last successful match will be used in place of the use element.	String	null	yes
