DynamicTapDance

The DynamicTapDance plugin allows one to set up TapDance keys without the need to compile and flash new firmware: one can change dynamic dances via Focus, using a tool like Chrysalis.

Dynamic dances come with certain limitations, however: unlike the built-in ones, dynamic ones do not support running custom code. They can only choose a key from a list of possibilities. Given a list of keys, the plugin will choose the one corresponding to the number of taps on the key, just like TapDance itself does.

Basically, this plugin allows us to store tapDanceActionKeys key lists in the on-board memory of our keyboard.

You can define up to 16 dynamic dances, there is no limit on their length, except the amount of storage available on the keyboard. You can even mix them with built-in dances! But the total number of tap-dances is 16.

Using the plugin

To use the plugin, we need to include the header, tell the firmware to use the plugin, and reserve storage space for the dances. This is best illustrated with an example:

#include <Kaleidoscope.h>
#include <Kaleidoscope-EEPROMSettings.h>
#include <Kaleidoscope-FocusSerial.h>
#include <Kaleidoscope-TapDance.h>
#include <Kaleidoscope-DynamicTapDance.h>

KALEIDOSCOPE_INIT_PLUGINS(
  EEPROMSettings,
  Focus,
  TapDance,
  DynamicTapDance
);

void tapDanceAction(uint8_t tap_dance_index, KeyAddr key_addr, uint8_t tap_count, kaleidoscope::plugin::TapDance::ActionType tap_dance_action) {
  DynamicTapDance.dance(tap_dance_index, key_addr, tap_count, tap_dance_action);
}

void setup() {
  Kaleidoscope.setup();

  // 0 is the amount of built-in dances we have.
  // 128 is how much space (in bytes) we reserve for dances.
  DynamicTapDance.setup(0, 128);
}

Plugin methods

The plugin provides a DynamicTapDance object, with the following methods and properties available:

.setup(builtin_dances, size)

Reserves size bytes of storage for dynamic dances. This must be called from the setup() method of your sketch, otherwise dynamic tap-dances will not function.

The builtin_dances argument tells the plugin how many built-in dances there are.

.dance(index, key_addr, tap_count, tap_dance_action)

Performs a given dance (index) made on the key at key_addr address, which has been tapped tap_count times, and the action to perform is tap_dance_action.

This mirrors the overrideable tapDanceAction() method of TapDance, and is intended to be called from therein.

Focus commands

The plugin provides one Focus command: tapdance.ap.

tapdance.map [dances...]

Without arguments, displays all the stored dances. Each dance is terminated by an end marker (0, aka Key_NoKey), and the last dance is followed by an additional marker. The plugin will send back the entire dynamic tap-dance storage space, even data after the final marker.

With arguments, it replaces the current set of dynamic dances with the newly given ones. Dances are terminated by an end marker, and the last macro must be terminated by an additional one. It is up to the caller to make sure these rules are obeyed.

In both cases, the data sent or expected is a sequence of 16-bit values, a memory dump.
