I’ve released ack 2.28 to the CPAN. This release doesn’t add any major new features, but for those who like to customize things, there are two new help options: --help-colors and --help-rgb-colors.

The --help-colors option shows a chart of various color combinations using the standard eight ANSI terminal colors.

The --help-rgb-colors option shows a grid of the 216 colors possible using RGB color specifications.

Thanks to Bill Ricker for his work in getting the RGB color chart organized in a useful way, via the Convert::Color module.

ack is available on the CPAN, and also as a single-file download at beyondgrep.com.

Let me know if you find it useful.
