LibGDX WrappedText，但使用文本内的颜色（java）

Question

I have made some code in the past to check through text to find color codes that will change the color of the text. Ex:

Drawing this: Hello my name&b is john would give this as a result when drawn: Hello my name is john but "is john" would be in blue since i used the &b color code. I am basically imitating ansi but for java.

Now I would like to wrap the text exactly like LibGDX's BitMapFont.drawWrapped(...) but still use the color codes. Anyone know how to do this? I would probobly be able to figure it out eventually but I just wanted to know if there was a better way than mine.

There is support for color markup: Color Markup Language :

The BitmapFontCache class supports in-string colored text through a simple markup language.

Markup is disabled by default. Use the method BitmapFont.setMarkupEnabled() to turn it on/off.

The markup syntax is really simple but still versatile:

• [name] Sets the color by name. There are a few predefined colors, see the Colors.reset() method for an exhaustive list. Users can define their own colors through the methods of the Colors class.
• [#xxxxxxxx] Sets the color specified by the hex value xxxxxxxx in the form RRGGBBAA where AA is optional and defaults to 0xFF.
• [] Sets the color to the previous color (kind of optional end tag)
• [[ Escapes the left bracket.

Notice that color names are case-sensitive, cannot be empty, cannot start with neither # nor [, and cannot contain ]. Also, any occurrence of [ in the color name must not be escaped.

For a sample code see the test class BitmapFontTest .
