Regex doesn't work in syntax highlighting

[NotroDev]

Hi.
I have this regex:
https://regex101.com/r/P3WGak/1
And everywhere it works, but not in syntax highlighting.
I have this:

<Span foreground="#FF5555">
	<Begin>(&amp;[clkmno])+</Begin>
	<End>((?&lt;!&quot;)&quot;(?!&quot;))|((?&lt;=&quot;&quot;)&quot;(?!&quot;))</End>
</Span>

And, as you can see:

It doesn't work. Why?

I don't have the time to look at the regex, but I can tell you how to achieve your goal:

AvalonEdit/ICSharpCode.AvalonEdit/Highlighting/Resources/VB-Mode.xshd

Lines 24 to 30 in ed6f2b5

	<Span color="String">
	<Begin>"</Begin>
	<End>"</End>
	<RuleSet>
	<Span begin="&quot;&quot;" end="" />
	</RuleSet>
	</Span>

This matches "" as it's own nested span.

Hope this helps.

Thanks, but I really can't get it to work. Where should I do this? What should I change in "" regex?

I am not yet sure what you are trying to achieve... Can you post a screenshot of what the colors and text should look like? Thanks!

Hey, It should be like this

// Maybe I could somehow do "end on LAST quot" regex/something else?

Hmm... It was probably a good idea!

I will post a working example of what I had in mind in the evening.

I am not sure if I understand your use-case correctly, but this is what I would have used:

<?xml version="1.0"?>
<SyntaxDefinition name="Custom Highlighting" xmlns="http://icsharpcode.net/sharpdevelop/syntaxdefinition/2008">
	<Color name="String" foreground="Blue" />
	
	<RuleSet>
		<Span color="String">
			<Begin foreground="Red">"</Begin>
			<End foreground="Red">"</End>
			<RuleSet>
				<Span begin="&quot;&quot;" end="" foreground="Orange" />
			</RuleSet>
		</Span>
	</RuleSet>
</SyntaxDefinition>

Example:

Yes, I am not sure why you want to start the span on (&[clkmno])+

By setting foreground directly on the Begin and End attributes of Span you can customize the color directly.

[NotroDev]

Yes, I am not sure why you want to start the span on (&[clkmno])+

It's the color, &c = <red>
Yeah, thanks for it, but I think that my regex is a better solution.
Thanks for taking your time!

Hey.
Oh my god, it was 24 days!
I returned to my project and I need to reopen this 😢
When I get the idea to get the last quote, I didn't think of one situation: two or more "".
It breaks completely in it...

I can't use your solution. E.g. &c is the color code, and in my editor it previews it.
