Need some help with custom highlighting

[imcleo]

Hi, I'm self-taught. I have a custom scripting language (very simple) that I'm trying to do syntax highlighting for. I've read the docs + searched around the internet but I'm not understanding how to add a .xshd file for the custom highlighting... Could anyone help me please? ^^

AvalonEdit/ICSharpCode.AvalonEdit.Sample/Window1.xaml.cs

Lines 44 to 55 in 774b38e

	// Load our custom highlighting definition
	IHighlightingDefinition customHighlighting;
	using (Stream s = typeof(Window1).Assembly.GetManifestResourceStream("AvalonEdit.Sample.CustomHighlighting.xshd")) {
	if (s == null)
	throw new InvalidOperationException("Could not find embedded resource");
	using (XmlReader reader = new XmlTextReader(s)) {
	customHighlighting = ICSharpCode.AvalonEdit.Highlighting.Xshd.
	HighlightingLoader.Load(reader, HighlightingManager.Instance);
	}
	}
	// and register it in the HighlightingManager
	HighlightingManager.Instance.RegisterHighlighting("Custom Highlighting", new string[] { ".cool" }, customHighlighting);

Hope this helps!

Thanks for the reply! Could you explain to me what the string[] extensions param is for RegisterHighlighting?

It is used by the HighlightingManager.GetDefinitionByExtension method. It can be used to find the matching highlighting definition based on a given filename. Note, however, this is not used by AvalonEdit internally, but can be used by library users to retrieve the correct highlighting for a file.
