How it looks

How it works

When creating a pattern, capture groups should be used. All the capture groups will be highlighted.

1. Use every pattern and find matches in the token
2. Add the line background for line highlighting compatibility
3. Remove all the overlaps, so that every character is present only once and color is displayed correctly even in the case of overlaps.

What else

• fixed linesSubSequence out of bounds bug
• removed unnecessary token.isSeparator checks
