SyntaxPane is a basic syntax pane supports:

• customize syntax coloring
• customize keyboard shortcuts
• listen to user input easily

The libarary has implemented java syntax coloring adapter and other basic keyboard shortcuts.

• Keyboard shortcuts have been implemented
• Undo(CTRL + Z)
• Redo(CTRL + Y)
• Reduce one prefix tab of multi lines(Shift + tab when select more than zero text)

• Add jar file to your classpath

Change fixed UI color which show in SyntaxEditPane by setter function of SyntaxManager. Other dynamically changeable characteristic can be changed by setter function of SyntaxEditPane.

JFrame frame = new JFrame();
try {
	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	SyntaxEditPane pane = new SyntaxEditPane(new SyntaxManager(), new JavaCodeAdapter());
	frame.add(pane);
	frame.setSize(700, 500);
	frame.setVisible(true);
} catch (SyntaxException e) {
	e.printStackTrace();
}

1. implement AbstractCodeAdapter
2. use textArea.getStyledTextBody() to get all text, and change text on syntax pane
3. use textArea.getSyntaxPainter() to get painter which help you color the syntax
4. use textArea.getSyntaxHighlightingTool() to get highlight tool which help you highligh the text
5. use textArea.getSyntaxDocumentToo() to get document tool which help you analyze text

class YourAdapter implements AbstractCodeAdapter {
	@Override
	public void insertString(int offset, String text, SyntaxTextArea textArea) {
		// listen to text insertsion
	}

	@Override
	public void remove(int offset, String text, SyntaxTextArea textArea) {
		// listen to text removement
	}

	@Override
	public boolean replace(int offset, int length, String text, SyntaxTextArea textArea) {
		// listen to text replacement.
		// return true to make SyntaxTextArea replace the text by calling remove and
		// insertString as referred to above.
		// That is if you want to do some changes by yourself, return false, otherwise return true.
	}

	@Override
	public AttributeSet getDefaultAttributeSet() {
		// SyntaxTextArea gets default AttributeSet through this function
		// and use it to set the characteristic attribute before call insertString()
	}
}

• Implement com.syntax.ui.AbstractSyntaxHeader. Actually, AbstractSyntaxHeader is a JPanel so you can add anything to it. Besides, the abstract methods of AbstractSyntaxHeader provide you with callbacks which listen to various changing in syntax pane.

• Implement com.syntax.ui.AbstractSyntaxCaret. The only abstract method should be implemented is the callback of font changing. You can override public void paint(Graphics g) to draw customized shape or apply another color.

• Register com.syntax.manage.SyntaxCaretListener in com.syntax.ui.SyntaxTextArea
