First question:

Hi guys! I trying to understand how to make a custom editor in Eclipse using the plugin example with the XML editor. I'm not getting something:
public class XMLPartitionScanner extends RuleBasedPartitionScanner {
	public final static String XML_COMMENT = "__xml_comment";
	public final static String XML_TAG = "__xml_tag";

	public XMLPartitionScanner() {

		IToken xmlComment = new Token(XML_COMMENT);
		IToken tag = new Token(XML_TAG);

		IPredicateRule[] rules = new IPredicateRule[2];

		rules[0] = new MultiLineRule("<!--", "-->", xmlComment);
		rules[1] = new TagRule(tag);

		setPredicateRules(rules);
	}
}


What if in my case a single instruction is something like this?

font( arial, bold, 20) ( (v.degree >= 3 ) AND NOT ( v.label == "Roma" ) )\n


where the last char is the \n but the initial char could be any letter in the alphabet? Could I use a regexp in SingleLineRule?

Second question:
Since my text is a list of instruction like the one above, does it make sense to just have two partition? One for the comments and one for the instructions?

Third question:
I've already have my parser created with sableCC. Is it possibile to integrate it with the editor?
