What are the "basic" parts of the JS Mode

1

Hello,

I’d like to find out which are the necessary parts of the JS Mode in the sense of which parts do I really need for the minimum functionality of an editor…

@marijn - Could you explain?

Thanks!

Regards

I don’t know what you mean, but this sounds like something that could be cleared up by reading the manual.

Well, alright - then please answer me just this question:

I’ve the string “–kommentar 1” which fits the regex: /^-{2}.*/

I’ve following check:

if(stream.match(/^-{2}.*/)){
			return ret("comment", "comment");
		}

As you can see I want to colorize the string “–kommentar 1” …

But I’ll never reach this return. The regex should work…

Can you tell me why?

Thanks.

Hello Marijn!

Since stream.match() didn’t work in my case - i used a workaround:

indent preformatted text by 4 spaces
	var regexP = /P\./g;
			var regexRSDot = /RS\.\w*/g;
			var regexDTDot = /DT\./g;
			var regexDT = /DT_\w*/;
			var regexRS = /RS_\w*/;
			var regexFOAB = /FO\(AB\w*/;
			
			var string = stream.string;
			
			//var string = stream.string.replace(/^"(.*)"$/, '$1');
			
			var matchC = regexComment.exec(string);
			var matchP = regexP.exec(string);
			var matchRS = regexRS.exec(string);
			var matchRSDot = regexRSDot.exec(string);
			var matchDTDot = regexDTDot.exec(string);
			var matchDT = regexDT.exec(string);
			var matchFOAB = regexFOAB.exec(string);
			
			//if(stream.match(/^-{2}.*/)){
			if(matchC !== null){
				return ret("comment", "comment");
			}
			
			if (matchP !== null) {
				//var xp = stream.next();
				stream.skipToEnd();
				var z = stream.current();
				return ret("atom", "atom");
			}
			
			if(matchRS !== null){
				return ret("ruleset", "ruleset");
			}
			
			if(matchDT !== null){
				return ret("ruleset", "ruleset");
			}
			
			if(matchDTDot !== null){
				return ret("atom", "atom");
			}
			
			if(matchRSDot !== null){
				return ret("atom", "atom");
			}
			
			if(matchFOAB !== null){
				return ret("keyword", "keyword");
			}

The Regex Pattern will be recognized now. But unfortunately the whole line will be colorized and not just a subset.

How can I manage this?

Thank you.

Regards
