From ce8cc9219fca5dde077f1142d03d011b38d27479 Mon Sep 17 00:00:00 2001 From: Gergely Nagy Date: Wed, 20 Jul 2016 11:34:45 +0200 Subject: tap-dance: Support user_data for the callbacks Refactored the code a little, so all callbacks now receive a `user_data` pointer, which can be anything. As an example, the key pairs from `ACTION_TAP_DANCE_DOUBLE` now use this, and custom, built-in functions. This makes it easier to extend the tap dance functionality, and also simplifies the code a little.
