Expected Behavior

printf("\nLog starting date: %d-%s-01\n", year, months[month]);

So in this example, the commas and the semicolon should not be white.

Code snippet for test

printf("\nLog starting date: %d-%s-01\n", year, months[month]);

Hi @GroxDots! I'm Dosu and I’m helping the intellij-rainbow-brackets team.

Rainbow Brackets currently only supports highlighting brackets (round, square, squiggly, angle) and indent guides. There is no option or setting to highlight delimiters like commas or semicolons, and this feature is not present anywhere in the plugin’s code or UI configuration. No alternative plugins or workarounds for delimiter highlighting were found in the JetBrains plugin marketplace or related discussions. If you need delimiter highlighting, it would require a custom plugin or editor extension.

To reply, just mention @dosu.
