Kaleidoscope-Colormap

The Colormap extension provides an easier way to set up a different - static - color map per-layer. This means that we can set up a map of colors for each key, on a per-layer basis, and whenever a layer becomes active, the color map for that layer is applied on top of everything else. Colors are picked from a 15-color palette (or 16, if we disable transparency), provided by the LED-Palette-Theme plugin. The color map is stored in EEPROM, and can be easily changed via the Focus plugin, which also provides palette editing capabilities.

Using the extension

To use the extension, include the header, tell it the number of layers you have, register the Focus hooks, and it will do the rest.

#include <Kaleidoscope.h>
#include <Kaleidoscope-Colormap.h>
#include <Kaleidoscope-Focus.h>

void setup(void) {
  Kaleidoscope.use(&ColormapEffect, &Focus);

  Kaleidoscope.setup();
  
  ColormapEffect.max_layers(1);
  Focus.addHook(FOCUS_HOOK_LEDPALETTETHEME);
  Focus.addHook(FOCUS_HOOK_COLORMAP);
}

Extension methods

The extension provides an ColormapEffect singleton object, with a single method:

.max_layers(max)

Tells the extension to reserve space in EEPROM for up to max layers. Can only be called once, any subsequent call will be a no-op.

Focus commands

The plugin provides a single Focus hook, FOCUS_HOOK_COLORMAP, implementing the following command:

colormap.map

Without arguments, prints the color map: palette indexes for all layers.

With arguments, updates the color map with new indexes. One does not need to give the full map, the plugin will process as many arguments as available, and ignore anything past the last key on the last layer (as set by the .max_layers() method).
