Is there AvaloniaEdit.TextMate package?

[WhiteBlackGoose]

Hey. As far as I could understand, the demo is loading syntax packages from TextMate, but it doesn't seem to have a package.

Also. Would you think it'd make sense to make syntax highlighting "native" for TextEditor type?

[danipen]

About the first part afaik @Takoooooo is working on it.

About the second question. What do you exactly mean by "make syntax highlight native"?

[WhiteBlackGoose]

@danipen what I mean is that the demo looks and works awesome, but it appears that setting the syntax highlighting is not so easy. I personally dream of just syntaxHighlight="c#" property, but I believe you didn't make it so to allow some configurability... maybe there's some trade off between convenience and configurability?

(note that I'm quite a noob in GUI in general, so maybe my comments aren't relevant)

Well, as you may know, AvaloniaEdit is a port of AvalonEdit. It comes with its own syntax highlight built-in engine, and this is the default one right now. We need to maintain it for backward compatibility.

We added TextMate as an extension, this is the reason it cannot work "built-in". We may change that in the future.

But using TextMate is super easy. You can initialize text mate for a TextEditor in the following way:

  TextEditor textEditor = new TextEditor();
  TextMate.TextMate.Installation textMate = textEditor.InstallTextMate(ThemeName.DarkPlus);
  textMate.SetGrammarByLanguageId("csharp");

This looks easy, thanks. The reason I was asking is because I'm currently learning FuncUI, an MVU wrapper over Avalonia.FuncUI, for which it'd make sense to have it as a property. But I hope I'll be able to do it with attached properties... I'm making a FuncUI wrapper for your awesome component, so I guess I'll just use the TextMate extension via git modules.

@danipen hey, sorry for stupid questions 😅 , but how can I unset grammar for a text editor?

[danipen]

Just set a null grammar for your TextMate.Installation object:

textMate.SetGrammar(null);

[WhiteBlackGoose]

oh, so easy, thanks

@WhiteBlackGoose with this PR it will be simpler to setup in FuncUI.

You will be able to obtain a reference to the underlaying component.

[JaggerJo]

This often makes wrapping components a lot simpler

[WhiteBlackGoose]

Good to hear! I already managed to add some external properties to the component, now one can set the syntax highlighting with just one line. (though of course it makes it less capable than yours by default)

[Takoooooo]

Hey, we have recently released this package, if you are still interested feel free to use :)

[JaggerJo]

Nice!

Thanks, will give a look!

I can't seem to get the example listed above to work.

        TextEditor textEditor = new TextEditor();
        TextMate.TextMate.Installation textMate = textEditor.InstallTextMate(ThemeName.DarkPlus);
        textMate.SetGrammarByLanguageId("csharp");

I was trying to use 1.0.56 (the latest release) and I was getting the compile errors.
The type 'IRegistryOptions' is defined in an assembly that is not referenced.
You must add a reference to assembly 'TextMateSharp, Version=1.0.29.0, Culture=neutral, PublicKeyToken=null'.

I tried dropping back to 1.0.29. It compiles and runs without crashing/exceptions.
However, it neither changes the theme nor appears to set the grammar correctly.
I see no syntax highlighting.

Has something changed in the latest releases which makes the existing example obsolete?

We would really like this functionality to be part of our release.

Thx
