关于rich中预定义样式的优化

[Mr-Lixiaoqaing]

What problem does this feature solve?

formatter中使用rich，只能先在rich中定义好富文本对象，再在formatter中去使用（比如'{a|这段文本能使用a样式}'）。 希望能在formatter中使用一个计算出来的样式对象，比如 '{a|这段文本能使用a样式}' 这个a不再是预定义在rich中的对象，而是可以在formatter函数中定义的一个对象。这样在使用一些动态的字体颜色、背景色等会方便很多

What does the proposed API look like?

这是我想象中的样子。当formatter中没有定义a时，就使用rich中的a

TITLE

About the optimization of predefined styles in rich

BODY

What problem does this feature solve?

The rich can only be used in the formatter to define a rich text object in rich and then use it in format (e.g. '{a| this text can use a style}'). It is desirable to use a computed style object in formatter, such as '{a| this text can use a style}' This a is no longer an object predefined in rich, but an object that can be defined in the formatr function. This will be much more convenient in using some dynamic font colors, background colors, etc

What does the proposed API look like?

This is what I imagined. When a is not defined in formatter, a in rich is used

In most cases, it should be sufficient to use current implementation with several styles and set the name (like "a") dynamically.

[Mr-Lixiaoqaing]

是的，大部分场景使用预定义的样式是够用了。但是能让它更好用不是更好吗

[kitee0325]

动态的话

formatter:(value){
     let map = {
          valueA:richA,
          valueB:richB,
          ...
     }
     return `{${map[valueA]}|${valueA}}`
}

rich:{
    richA:{},
    richB:{}
}

这样就可以吧
