Full code colorization support for `.dib` files

[sharpchen]

What is a .dib file?

.dib is a format for representing notebook content, just like .ipynb for python. .dib is for some other languages for example C#, JavaScript based on .NET Interactive.

What extension I am using?

I am using Polyglot Notebook writing C# code. This extension supports both .dib and .ipynb, but the syntax highlighting is not working properly with .dib.

Working with .ipynb looks fine.

Code Snippet

public static double Closure(((double, double)[] b, (double, double)[] f) tuple) {
        var l = tuple.b.Zip(tuple.f, (x, y) => (backward:x, forward:y));
        return l.Select(x => {
            var f = x.backward.Item1 - x.forward.Item1;
            var s = x.backward.Item1 - x.forward.Item2;
            return (f + s) / 2;
        }).Sum();
}

Hi, @UPIMMUNITY

Sorry, I didn't write scope coloring rules specifically for .ipynb files, and I can't write scope coloring rules to support .dib files. They are not programming languages. I can't view the scope values of code blocks in .dib files.

All theme plugins add color to characters based on their scope value. All characters's scope value is given by VSCode. You can check them by pressing Ctrl+Shift+P (Windows) or Cmd+Shift+P (Mac) and selecting Inspect Editor Tokens and Scopes.

I have reviewed your .dib file using all the themes installed on my VSCode, and none of them have been colored for the code blocks, including the default theme for VSCode.

So you may got the logic wrong. It's not the theme that needs to support .dib files, but .dib files need to add the feature of importing code themes for display. So you may need to raise an issue under the Polyglot Notebook plugin.

@fisheva I see, you're right. Nothing is colorized without semantic highlighting.
