Kaleidoscope-MacrosOnTheFly

This plugin allows you to record and playback macros on-the-fly. Do any sequence of keystrokes once, then repeat it with the tap of a button. Some possible uses including typing some text over and over; invoking a complicated shortcut several times; or (for programmers like me) making the same modification to several different lines of code. Furthermore, you can have as many different macros stored at once as you have keys on your keyboard, and play back any of them at any time. The possibilities are limited only by your imagination.

The organization and control scheme for MacrosOnTheFly is inspired by the similar feature in Vim. Vim users should feel right at home. This plugin simply takes that functionality and bakes it into your keyboard, so that it works in any application and context wherever you go. That said, using this plugin does not require any Vim knowledge at all - it is fully explained below.

Before we start: Alternatives to this plugin

MacrosOnTheFly is a powerful plugin. However, if you already know what key sequences you want to put on what buttons, consider using the plugin instead, which will bake them into your keymap and is more efficient than recording and playing back on the fly. Also, macros recorded on the fly will be cleared whenever the keyboard loses power, whereas macros from the Macros plugin are permanent (until you reflash your firmware, that is).

If the only reason you want to use this plugin over Macros is because of its large number of available macro slots, consider adding a new layer to your keymap and marking it up with macros from Macros (you can access this layer in any number of ways, including with a key).

If you're excited by the ability to create custom key-sequences on demand that are tailored to your particular situation, and work in any application and context - this is the plugin for you! Read on.

Installing this plugin

Install this plugin as you would any other 3rd-party plugin. Specifically:

1. Find your plugin directory. This is wherever you normally put plugins; it should be $SKETCHBOOK_DIR/hardware/keyboardio/avr/libraries, or at least accessible from there via symlink. (If you don't know what a symlink is, don't worry - just use the libraries directory directly.) $SKETCHBOOK_DIR is your Arduino sketchbook directory, perhaps $HOME/Arduino or $HOME/Documents/Arduino.
2. Install this plugin into your plugin directory using one of the below options.

• (Option 1 - using Git) Clone this Git repo into your plugin directory. This can be done from the command line - just navigate to your plugin directory and type git clone https://github.com/cdisselkoen/Kaleidoscope-MacrosOnTheFly.
• (Option 2 - no Git or command-line required) Click the green "Clone or download" button at the top right of this page, and select "Download ZIP". Then, unzip the folder in your plugin directory.

You're done! It was that easy.

Adding the plugin to your sketch

To activate the plugin, one needs to include the header, tell Kaleidoscope to use the plugin, and place the Key_MacroRec and Key_MacroPlay keys on the keymap.

In general, this plugin desires to be as early as possible in the KALEIDOSCOPE_INIT_PLUGINS order, so that it can catch all keypresses before other plugins try to handle them. There may be exceptions.

Setup operations in the firmware sketch (example):

#include <Kaleidoscope.h>
#include <Kaleidoscope-MacrosOnTheFly.h>

KALEIDOSCOPE_INIT_PLUGINS(MacrosOnTheFly);

Keymap markup

Somewhere on the keymap, you should place the special keys Key_MacroRec and Key_MacroPlay, which are used for macro recording and playback respectively. Note these keys can be on any layer or on different layers - they could even be the same key on different layers.

Starting from a layout reasonably close to the default Model 01 QWERTY layout, some suggestions for places to put these keys are:

• the pgup and pgdn keys
• the enter key (if like me you use Fn-Space or some other key as 'enter')
• the tab key (if like me you've remapped it somewhere else)
• Fn-q (if you like similarity to Vim)
• Fn-; or Fn-' (both empty in the default firmware)
• the any key
• the prog key
• the butterfly key

Using the plugin

After installing the firmware, you can use the Key_MacroRec and Key_MacroPlay keys to record and play back macros on-the-fly.

MacrosOnTheFly provides a large number of storage slots for macros; you can record and play back any of them at any time. Each of the keys on your keyboard is a storage slot, so you have a Slot A, a Slot X, a Slot 4, a Slot Enter - even a slot for each thumb key and palm key. The only exception is that the Key_MacroPlay key is not a slot - but Key_MacroRec is a slot. You can use any combination of these storage slots you want, at any time.

Recording a macro

To start recording, tap the Key_MacroRec key followed by the key for the particular slot you want to record into. Then type whatever sequence of keys you want to record. Finally, to stop recording, tap the Key_MacroRec key again. For example, the sequence:

Key_MacroRec, q, h, e, l, l, o, Key_MacroRec

records the five-key sequence "hello" into the q slot.

You can record pretty much any action into a macro: you can use modifiers, layer switches, and even other macros - either static macros created with , or other OnTheFly macros. In any case, when you play back your recorded macro, it will repeat exactly the same actions as you made when you recorded it.

Playing back a macro

To play back a macro, simply tap the Key_MacroPlay key followed by the key for the slot you want to play. Alternately, double-tapping Key_MacroPlay will replay whichever macro you most recently played. Continuing the example, from above, the sequence:

Key_MacroPlay, q

will type the five-key sequence "hello"; and then the sequence:

Key_MacroPlay, Key_MacroPlay

(or just Key_MacroPlay+q again) will type the five-key sequence "hello" again.

Plugin options

The plugin provides the MacrosOnTheFly object, which has the following public properties:

.modsAreSlots

If this is set to true, then modifier keys (like Shift, Control, etc) and layer keys (both ShiftToLayer() and LockLayer() keys) will be usable slots in their own right - i.e. you will have a Shift slot, a Control slot, etc. If this is set to false (the default), then modifier and layer keys are not their own slots, but instead unlock entire additional "layers" of slots - i.e. k, Shift+k, Ctrl+k, Alt+k, and even Shift+Ctrl+k or Ctrl+Alt+k etc are all different macro slots. Likewise, you will also have slots for any keys on other layers of your keyboard.

.colorEffects

If this is set to true (the default), the keyboard will use various colored LED effects to communicate what's happening. Specifically:

• While recording a macro, the Key_MacroRec key will be illuminated in green, and the selected slot's key will be illuminated in white.
• When done (successfully) recording a macro, the whole keyboard will momentarily flash green.
• If a macro-record option fails (for instance, if you exceed the storage capacity), the whole keyboard will momentarily flash red.
• When a macro playback completes, the Key_MacroPlay key will momentarily flash green and the played slot will momentarily flash white.
• If you try to playback a macro slot which you haven't recorded anything into, the Key_MacroPlay key and the selected slot will momentarily flash red.

The specific colors mentioned above are the defaults, and can be customized using the properties below.

The mentioned LED effects should play over top of all other LED effects, in particular any active LED modes. If you find they don't, please let me know by opening an issue on this GitHub.

.recordColor

The color to use for the Key_MacroRec key during recording. Default is CRGB(0,255,0).

.slotColor

The color to use for the selected slot's key during recording or after successful playback. Default is CRGB(255,255,255).

.successColor

The color to momentarily flash the keyboard after successful recording. Default is CRGB(0,200,0).

.failColor

The color to momentarily flash the keyboard after recording failure (for instance, if the storage capacity is exceeded). Default is CRGB(200,0,0).

.playColor

The color to momentarily flash the Key_MacroPlay key when macro playback completes. Default is CRGB(0,255,0).

.emptyColor

The color to momentarily flash the Key_MacroPlay key and the selected slot's key if there is no macro recorded in the selected slot. Default is CRGB(255,0,0).

Limitations

• There is a finite amount of storage available in your keyboard. In the event that you are recording a macro and exceed the total storage limit, the "record" operation will stop, and (if .colorEffects is set to true, its default), the keyboard will momentarily flash red (or the color that .failColor is set to, if not the default). This will happen more quickly if you record very long macros and/or use a lot of slots simultaneously. You can free up storage space by deleting macros you've already recorded (just record an empty macro over them, using Key_MacroRec+key+Key_MacroRec), or reset everything by powering your keyboard off and on, which will clear all your stored macros.

• Recorded macros remain in your keyboard until you record over them, or until the keyboard loses power. If you want your macros to stay in the keyboard even after it loses power, use the plugin instead.
