      public class RSyntaxTextArea
      extends RTextArea
      implements SyntaxConstants

  An extension of `RTextArea` that adds syntax highlighting of certain programming languages to its list of features. Languages currently supported include:

  - ActionScript
  - Assembler (X86)
  - BBCode
  - C
  - C++
  - CSS
  - C#
  - Clojure
  - Dart
  - Delphi
  - DTD
  - Fortran
  - Groovy
  - HTML
  - htaccess
  - Java
  - JavaScript
  - .jshintrc
  - JSP

  - LaTeX
  - Lisp
  - Lua
  - Make
  - MXML
  - NSIS
  - Perl
  - PHP
  - Properties files
  - Python
  - Ruby
  - SAS
  - Scala
  - SQL
  - Tcl
  - UNIX shell scripts
  - Visual Basic
  - Windows batch
  - XML files

  Other added features include:
  - Code folding
  - Bracket matching
  - Auto-indentation
  - Copy as RTF
  - Clickable hyperlinks (if the language scanner being used supports it)
  - A pluggable "parser" system that can be used to implement syntax validation, spell checking, etc.
  It is recommended that you use an instance of `RTextScrollPane` instead of a regular `JScrollPane` as this class allows you to add line numbers and bookmarks easily to your text area.

      Note that basic users of `RSyntaxTextArea` will not call this method directly; rather, it is usually called by instances of `LanguageSupport` in the `RSTALangaugeSupport` library. See http://fifesoft.com for more information about this library.

      Parameters:

    - #### setPaintMatchedBracketPair

          public void setPaintMatchedBracketPair​(boolean paintPair)

      Sets whether the bracket at the caret position is painted as a "match" when a matched bracket is found. Note that this property does nothing if `isBracketMatchingEnabled()` returns `false`.

      This method fires a property change event of type `PAINT_MATCHED_BRACKET_PAIR_PROPERTY`.

      Parameters:
        `paintPair` - Whether both brackets in a bracket pair should be highlighted when bracket matching is enabled.
      See Also:
        `getPaintMatchedBracketPair()`, `isBracketMatchingEnabled()`, `setBracketMatchingEnabled(boolean)`

    - #### setPaintTabLines

          public void setPaintTabLines​(boolean paint)

      Toggles whether tab lines are painted. This method fires a property change event of type `TAB_LINES_PROPERTY`.
      Parameters:
        `paint` - Whether tab lines are painted.
      See Also:
        `getPaintTabLines()`, `setTabLineColor(Color)`

    - #### setParserDelay

          public void setParserDelay​(int millis)

      Sets the parser delay. This is the delay that must occur between edits for any registered `Parser`s to run.
      Parameters:
        `millis` - The new parser delay, in milliseconds. This must be greater than zero.
      See Also:
        `getParserDelay()`

    - #### setRightHandSideCorrection

          public void setRightHandSideCorrection​(int rhsCorrection)

      Applications typically have no need to modify this value.

      Workaround for JTextComponents allowing the caret to be rendered entirely off-screen if the entire "previous" character fit entirely.

      Parameters:
        `rhsCorrection` - The amount of space to add to the x-axis preferred span. This should be non-negative.
      See Also:
        `getRightHandSideCorrection()`

    - #### setSecondaryLanguageBackground

          public void setSecondaryLanguageBackground​(int index,
                                                     Color color)

      Sets the background color to use for a secondary language.
      Parameters:
        `index` - The language index. Note that these are 1-based, not 0-based, and should be in the range `1-getSecondaryLanguageCount()`, inclusive.
        `color` - The new color, or `null` for none.
      See Also:
        `getSecondaryLanguageBackground(int)`, `getSecondaryLanguageCount()`

    - #### setSyntaxEditingStyle

          public void setSyntaxEditingStyle​(String styleKey)

      Sets what type of syntax highlighting this editor is doing. This method fires a property change of type `SYNTAX_STYLE_PROPERTY`.
      Parameters:
        `styleKey` - The syntax editing style to use, for example, `SyntaxConstants.SYNTAX_STYLE_NONE` or `SyntaxConstants.SYNTAX_STYLE_JAVA`.
      See Also:
        `getSyntaxEditingStyle()`, `SyntaxConstants`

    - #### setSyntaxScheme

          public void setSyntaxScheme​(SyntaxScheme scheme)

      Sets all of the colors used in syntax highlighting to the colors specified. This uses a shallow copy of the color scheme so that multiple text areas can share the same color scheme and have their properties changed simultaneously.

      This method fires a property change event of type `SYNTAX_SCHEME_PROPERTY`.

      Parameters:
        `scheme` - The instance of `SyntaxScheme` to use.
      See Also:
        `getSyntaxScheme()`

    - #### setTemplateDirectory

          public static boolean setTemplateDirectory​(String dir)

      If templates are enabled, all currently-known templates are forgotten and all templates are loaded from all files in the specified directory ending in "*.xml". If templates aren't enabled, nothing happens.
      Parameters:
        `dir` - The directory containing files ending in extension `.xml` that contain templates to load.
      Returns:
        `true` if the load was successful; `false` if either templates aren't currently enabled or the load failed somehow (most likely, the directory doesn't exist).
      See Also:
        `getTemplatesEnabled()`, `setTemplatesEnabled(boolean)`, `saveTemplates()`

    - #### setTemplatesEnabled

          public static void setTemplatesEnabled​(boolean enabled)

      Enables or disables templates.

      Templates are a set of "shorthand identifiers" that you can configure so that you only have to type a short identifier (such as "forb") to insert a larger amount of code into the document (such as:

             for (<caret>) {

             }

      Templates are a shared resource among all instances of `RSyntaxTextArea`; that is, templates can only be enabled/disabled for all text areas globally, not individually, and all text areas have access of the same templates. This should not be an issue; rather, it should be beneficial as it promotes uniformity among all text areas in an application.

      For more flexible boilerplate code insertion, consider using the TemplateCompletion class in the AutoComplete add-on library.

      Parameters:
        `enabled` - Whether or not templates should be enabled.
      See Also:
        `getTemplatesEnabled()`

    - #### setTabLineColor

          public void setTabLineColor​(Color c)

      Sets the color use to paint tab lines. This method fires a property change event of type `TAB_LINE_COLOR_PROPERTY`.
      Parameters:
        `c` - The color. If this value is `null`, the default (gray) is used.
      See Also:
        `getTabLineColor()`, `setPaintTabLines(boolean)`, `getPaintTabLines()`

    - #### setUseFocusableTips

          public void setUseFocusableTips​(boolean use)

      Sets whether "focusable" tool tips are used instead of standard ones. Focusable tool tips are tool tips that the user can click on, resize, copy from, and clink links in. This method fires a property change event of type `FOCUSABLE_TIPS_PROPERTY`.
      Parameters:
        `use` - Whether to use focusable tool tips.
      See Also:
        `getUseFocusableTips()`, `FocusableTip`

    - #### setUseSelectedTextColor

          public void setUseSelectedTextColor​(boolean use)

      Sets whether selected text should use the "selected text color" property (set via `JTextComponent.setSelectedTextColor(Color)`). This is the typical behavior of text components. By default, RSyntaxTextArea does not do this, so that token styles are visible even in selected regions of text. This method fires a property change event of type `USE_SELECTED_TEXT_COLOR_PROPERTY`.
      Parameters:
        `use` - Whether to use the "selected text" color when painting text in selected regions.
      See Also:
        `getUseSelectedTextColor()`

    - #### setWhitespaceVisible

          public void setWhitespaceVisible​(boolean visible)

      Sets whether whitespace is visible. This method fires a property change of type `VISIBLE_WHITESPACE_PROPERTY`.
      Parameters:
        `visible` - Whether whitespace should be visible.
      See Also:
        `isWhitespaceVisible()`

    - #### undoLastAction

          public void undoLastAction()

      Attempt to undo an "action" done in this text area.
      Overrides:
        `undoLastAction` in class `RTextArea`
      See Also:
        `RTextArea.redoLastAction()`

    - #### viewToToken

          public Token viewToToken​(Point p)

      Returns the token at the specified position in the view.
      Parameters:
        `p` - The position in the view.
      Returns:
        The token, or `null` if no token is at that position.
      See Also:
        `modelToToken(int)`
