Splitting (or getting a part of) OrderedText

[efekos]

Description

Hello. I wanted to make a TextComponentWidget, a widget that is basically a TextFieldWidget, but gets Text instead of String. I managed to make everything needed to make the widget function properly. Parsing looks good, preview looks good. But there is a tiny problem. I wanted to change the color of input shown at the text box, and I used render text provider for that. Here is the code:

setRenderTextProvider((string, cursor) -> {
            MutableText literal = Text.literal(string);

            if(!displayMode) {

                try {
                    Text.Serializer.fromJson(getText()); // this is json mode and nothing really specific (yet)
                    return literal.formatted(Formatting.YELLOW).asOrderedText();
                } catch (Exception ignored){
                    return literal.formatted(Formatting.RED).asOrderedText();
                }

            } else {
                // this is the text. I use a custom text class then convert it to MutableText, and then convert that MutableText
                // list to ordered text at here.
                OrderedText orderedText = OrderedText.concat(TextParser.parseText(getText()).stream().map(dev.efekos.dev_tools.client.screen.widget.Text::toText).map(Text::asOrderedText).toList());

                return orderedText; //TODO split this
            }
        });

As you can see, I parse the entire input, and return it at display mode. But it turns out that I have to only include the part that string is. I tried parsing string instead of all the output, but it completely breaks the parser.

I guess I have to split the OrderedText or make a sub text out of it. How do I do that? I never used an OrderedText before, and I have no idea how can I do it.
