Exception is thrown when making a new line

[AlphaNecron]

Kide_Ce7fskTPt1.mp4

This happens only when I add tm.SetGrammar(ropts.GetScopeByLanguageId(ropts.GetLanguageByExtension(".cs").Id));

Is there any solution?

@AlphaNecron. I tried the demo application and I cannot reproduce it.

Could you share a minimal sample that reproduces the issue? I'll try to fix. Thanks in advance

[AlphaNecron]

Can i send the project to your email?

[danipen]

Well, just share here how you instantiate the Avalonia Text Editor and how you set up TextMate just to help me to reproduce the issue.

       <avaloniaEdit:TextEditor x:Name="MainEditor" Padding="4"

            var ropts = new RegistryOptions(ThemeName.DarkPlus);
            var editor = this.FindControl<TextEditor>("MainEditor");
            editor.TextArea.Caret.PositionChanged += delegate
            {
                ViewModel!.CaretPos = editor.TextArea.Caret.Position.Location;
            };
            editor.TextArea.SelectionBrush = new SolidColorBrush
            {
                Color = Color.FromRgb(38, 78, 119),
                Opacity = 0.4
            };
            editor.TextArea.SelectionCornerRadius = 2;
            editor.TextArea.SelectionForeground = new SolidColorBrush
            {
                Color = Color.FromRgb(248, 250, 251)
            };
            editor.TextArea.IndentationStrategy = new CSharpIndentationStrategy();
            var tm = editor.InstallTextMate(ropts);
            tm.SetGrammar(ropts.GetScopeByLanguageId(ropts.GetLanguageByExtension(".pas").Id));
            tm.SetTheme(ropts.LoadTheme(ThemeName.DarkPlus));

I'm sorry I'm unable to reproduce the issue. Can you reproduce the issue in the "Demo" application?

[danipen]

I cannot:

pascal.mp4

[AlphaNecron]

https://github.com/AlphaNecron/Kide Here's the repo, you can try and see.

[danipen]

Reproduced using your sample. I'll provide a fix for it.

Note that re-setting the document text here makes editing incredible slow (and that unveiled a sync issue in TextMateSharp).

It's a part of the MVVM example of AvaloniaEdit tho.

Is there another way to do this?

Sorry I'm not familiar with the MVVM sample of avalonia edit. @Takoooooo can you help with this?
