According to this entry in the Mint support forum, wet_slimpattern can easily be adapted to integrate Mint into a Textpattern installation as well.
Thus, I’ve added one more line into the plugin’s code. Mint logging is enabled by removing the hash (#) in front of this line:
Logging for SlimStat is disabled by adding the hash to the preceeding line in a similar way:
# @include_once( $_SERVER["DOCUMENT_ROOT"]."/slimstat/inc.stats.php" );
An in-depth description of wet_slimpattern is here.
According to Shaun Inman, this integration is covered by the licenses of both Textpattern and Mint.
Please note: As I do not own a copy of Mint I’d leave real life tests up to some courageous souls who are kindly asked to add feedback at the comments.
