-If you're just getting started with the Keyboardio Model 01, the [introductory docs are here](https://github.com/keyboardio/Kaleidoscope/wiki/Keyboardio-Model-01-Introduction) and the source for the basic firmware package is here: https://github.com/keyboardio/Model01-Firmware. It's probably a good idea to start there, learn how to modify your keymap and maybe turn some modules on or off, and then come back to the full repository when you have more complex changes in mind.

+"""Run `include-what-you-use` on Kaleidoscope sources
+
+This is a script for maintenance of the headers included in Kaleidoscope source
+files.  It is not currently possible to run this automatically on all
+Kaleidoscope source files, because of the peculiarities therein.  It uses
+llvm/clang to determine which headers should be included in a given file, but
+there's no avr-clang, so we're limited to using the virtual hardware device.
+
+It takes any number of source files as its input, examines them and updates the
+list of header `#include` directives.
+
+It is safe to run on most Kaleidoscope source files, and a good idea to run it
+on new ones (after staging them, so you can easily see what changes have been
+made).

+### Sketch preprocssing system
+
+We used to support the ability to amend all compiled sketches by
+adding code to
+`src/kaleidoscope_internal/sketch_preprocessing/sketch_header.h`
+and `src/kaleidoscope_internal/sketch_preprocessing/sketch_footer.h`.
+The functionality was never used by Kaleidoscope itself and frequently
+pulled the (empty) header files from the wrong copy of Kaleidoscope.
+If you need this functionality, please open a GitHub issue.
+
+### Macros
+
+This is a guide to upgrading existing Macros code to use the new version of
+Kaleidoscope and the Macros plugin.
+
+#### New `macroAction()` function
+
+There is a new version of the `macroAction()` function, which is the entry point
+for user-defined Macros code. The old version takes two integer parameters, with
+the following call signature:
+
+```c++
+const macro_t* macroAction(uint8_t macro_id, uint8_t key_state)
+```
+
+If your sketch has this function, with a `key_state` bitfield parameter, it
+might still work as expected, but depending on the specifics of the code that
+gets called from it, your macros might not work as expected. Either way, you
+should update that function to the new version, which takes a `KeyEvent`
+reference as its second parameter:
+
+```c++
+const macro_t* macroAction(uint8_t macro_id, KeyEvent &event)
+```
+
+For simple macros, it is a simple matter of replacing `key_state` in the body of
+the `macroAction()` code with `event.state`. This covers most cases where all
+that's done is a call to `Macros.type()`, or a `MACRO()` or `MACRODOWN()`
+sequence is returned.
+
+
+#### Using `MACRO()` and `MACRODOWN()`
+
+The preprocessor macro `MACRODOWN()` has been deprecated, because the event
+handler for Macros is no longer called every cycle, but only when a key is
+either pressed or released.  Instead of using `return MACRODOWN()`, you should
+test for a toggle-on event in `macroAction()` and use `MACRO()` instead.  If you
+previously had something like the following in your `macroAction()` function:
+
+```c++
+switch(macro_id) {
+case MY_MACRO:
+  return MACRODOWN(T(X), T(Y), T(Z));
+}
+```
+
+...you should replace that with:
+
+```c++
+switch(macro_id) {
+case MY_MACRO:
+  if (keyToggledOn(event.state))
+    return MACRO(T(X), T(Y), T(Z));
+}
+```
+
+...or, for a group of macros that should only fire on keypress:
+
+```c++
+if (keyToggledOn(event.state)) {
+  switch(macro_id) {
+  case MY_MACRO:
+    return MACRO(T(X), T(Y), T(Z));
+  case MY_OTHER_MACRO:
+    return MACRO(T(A), T(B), T(C));
+  }
+}
+```
+
+#### Releasing keys with `Macros.release()` or `U()`/`Ur()`/`Uc()`
+
+Macros now operates by manipulating keys on a small supplemental virtual
+keyboard when using `Macros.press()` and `Macros.release()` (which are called by
+`D()` and `U()`, _et al_, respectively).  This means that it has no built-in
+facility for releasing other keys that are held on the keyboard.  For example,
+if you had a Macro that removed `shift` keycodes from the HID report in the
+past, it won't work.  For example:
+
+```c++
+  case KEY_COMMA:
+    if (keyToggledOn(event.state)) {
+      if (Kaleidoscope.hid().keyboard().wasModifierKeyActive(Key_LeftShift)) {
+        return MACRO(U(LeftShift), T(Comma), D(LeftShift));
+      } else {
+        return MACRO(T(M));
+      }
+    }
+```
+
+In this case, holding a physical `Key_LeftShift` and pressing `M(KEY_COMMA)`
+will not cause the held `shift` to be released, and you'll get a `<` instead of
+the intended `,` (depending on the OS keymap).  To accomplish this, you'll need
+a small plugin like the following in your sketch:
+
+```c++
+namespace kaleidoscope {
+namespace plugin {
+
+// When activated, this plugin will suppress any `shift` key (including modifier
+// combos with `shift` a flag) before it's added to the HID report.
+class ShiftBlocker : public Plugin {
+
+ public:
+  EventHandlerResult onAddToReport(Key key) {
+    if (active_ && key.isKeyboardShift())
+      return EventHandlerResult::ABORT;
+    return EventHandlerResult::OK;
+  }
+
+  void enable() {
+    active_ = true;
+  }
+  void disable() {
+    active_ = false;
+  }
+
+ private:
+  bool active_{false};
+
+};
+
+} // namespace plugin
+} // namespace kaleidoscope
+
+kaleidoscope::plugin::ShiftBlocker ShiftBlocker;
+```
+
+You may also need to define a function to test for held `shift` keys:
+
+```c++
+bool isShiftKeyHeld() {
+  for (Key key : kaleidoscope::live_keys.all()) {
+    if (key.isKeyboardShift())
+      return true;
+  }
+  return false;
+}
+```
+
+Then, in your `macroAction()` function:
+
+```c++
+  if (keyToggledOn(event.state)) {
+    switch (macro_id) {
+    case MY_MACRO:
+      if (isShiftKeyHeld()) {
+        ShiftBlocker.enable();
+        Macros.tap(Key_Comma);
+        ShiftBlocker.disable();
+      } else {
+        Macros.tap(Key_M);
+      }
+      return MACRO_NONE;
+    }
+  }
+```
+
+In many simple cases, such as the above example, an even better solution is to
+use the CharShift plugin instead of Macros.
+
+#### Code that calls `handleKeyswitchEvent()` or `pressKey()`
+
+It is very likely that if you have custom code that calls
+`handleKeyswitchEvent()` or `pressKey()` directly, it will no longer function
+properly after upgrading. To adapt this code to the new `KeyEvent` system
+requires a deeper understanding of the changes to Kaleidoscope, but likely
+results in much simpler Macros code.
+
+The first thing that is important to understand is that the `macroAction()`
+function will now only be called when a Macros `Key` toggles on or off, not once
+per cycle while the key is held.  This is because the new event handling code in
+Kaleidoscope only calls plugin handlers in those cases, dealing with one event
+at a time, in a single pass through the plugin event handlers (rather than one
+pass per active key)--and only sends a keyboard HID report in response to those
+events, not once per scan cycle.
+
+This means that any Macros code that is meant to keep keycodes in the keyboard
+HID report while the Macros key is held needs to be changed. For example, if a
+macro contained the following code:
+
+```c++
+if (keyIsPressed(key_state)) {
+  Runtime.hid().keyboard().pressKey(Key_LeftShift);
+}
+```
+
+...that wouldn't work quite as expected, because as soon as the next key is
+pressed, a new report would be generated without ever calling `macroAction()`,
+and therefore that change to the HID report would not take place, effectively
+turning off the `shift` modifier immediately before sending the report with the
+keycode that it was intended to modify.
+
+Furthermore, that `shift` modifier would never even get sent in the first place,
+because the HID report no longer gets cleared at the beginning of every
+cycle. Now it doesn't get cleared until _after_ the plugin event handlers get
+called (in the case of Macros, that's `onKeyEvent()`, which calls the
+user-defined `macroAction()` function), so any changes made to the HID report
+from that function will be discarded before it's sent.
+
+Instead of the above, there are two new mechanisms for keeping keys active while
+a Macros key is pressed:
+
+##### Alter the `event.key` value
+
+If your macro only needs to keep a single `Key` value active after running some
+code, and doesn't need to run any custom code when the key is released, the
+simplest thing to do is to override the event's `Key` value:
+
+```c++
+if (keyToggledOn(event.state)) {
+  // do some macro action(s)
+  event.key = Key_LeftShift;
+}
+```
+
+This will (temporarily) replace the Macros key with the value assigned (in this
+case, `Key_LeftShift`), starting immediately after the `macroAction()` function
+returns, and lasting until the key is released. This key value can include
+modifier flags, or it can be a layer-shift, or any other valid `Key` value
+(though it won't get processed by plugins that are initialized before Macros in
+`KALEIDOSCOPE_INIT_PLUGINS()`, and Macros itself won't act on the value, if it
+gets replaced by a different Macros key).
+
+##### Use the supplemental Macros `Key` array
+
+The Macros plugin now contains a small array of `Key` values that will be
+included when building HID reports triggered by subsequent, non-Macros
+events. To use it, just call one (or more) of the following methods:
+
+```c++
+Macros.press(key);
+Macros.release(key);
+Macros.tap(key)
+```
+
+Each one of these functions generates a new artificial key event, and processes
+it (including sending a HID report, if necessary). For `press()` and
+`release()`, it also stores the specified key's value in the Macros supplemental
+`Key` array. In the case of the `tap()` function, it generates matching press
+and release events, but skips storing them, assuming that no plugin will
+generate an intervening event. All of the events generated by these functions
+will be marked `INJECTED`, which will cause Macros itself (and many other
+plugins) to ignore them.
+
+This will allow you to keep multiple `Key` values active while a Macros key is
+held, while leaving the Macros key itself active, enabling more custom code to
+be called on its release.  Note that whenever a Macros key is released, the
+supplemental key array is cleared to minimize the chances of keycodes getting
+"stuck". It is still possible to write a macro that will cause values to persist
+in this array, however, by combining both a sequence that uses key presses
+without matched releases _and_ replacing `event.key` (see above) in the same
+macro.
+
+##### Borrow an idle key (not recommended)
+
+It's also possible to "borrow" one (or more) idle keys on the keyboard by
+searching the `live_keys[]` array for an empty entry, and generating a new event
+with the address of that key. This is not recommended because surprising things
+can happen if that key is then pressed and released, but it's still an option
+for people who like to live dangerously.
+
+#### Code that calls `sendReport()`
+
+Calling `sendReport()` directly from a macro is now almost always unnecessary.
+Instead, a call to `Runtime.handleKeyEvent()` will result in a keyboard HID
+report being sent in response to the generated event without needing to make it
+explicit.
+
+#### Code that uses `Macros.key_addr`
+
+This variable is deprecated. Instead, using the new `macroAction(id, event)`
+function, the address of the Macros key is available via the `event.addr`
+variable.
+
+#### Working with other plugins
+
+##### Plugin-specific `Key` values
+
+When the the Macros plugin generates events, it marks the event state as
+`INJECTED` in order to prevent unbounded recursion (Macros ignores injected
+events).  This causes most other plugins to ignore the event, as well.
+Therefore, including a plugin-specific key (e.g. a OneShot modifier such as
+`OSM(LeftAlt)`) will most likely be ignored by the target plugin, and will
+therefore not have the desired effect. This applies to any calls to
+`Macros.play()` (including returning `MACRO()` from `macroAction()`),
+`Macros.tap()`, `Macros.press()`, and `Macros.release()`.
+
+##### Physical event plugins
+
+Macros cannot usefully produce events handled by plugins that implement the
+`onKeyswitchEvent()` handler, such as Qukeys, TapDance, and Leader.  To make
+those plugins work with Macros, it's necessary to have the other plugin produce
+a Macros key, not the other way around. A `macroAction()` function must not call
+`Runtime.handleKeyswitchEvent()`.
+
+##### OneShot
+
+This is one plugin that you might specifically want to use with a macro,
+generally at the end of a sequence.  For example, a macro for ending one
+sentence and beginning the next one might print a period followed by a space
+(`. `), then a OneShot shift key tap, so that the next character will be
+automatically capitalized. The problem, as mentioned before is that the
+following won't work:
+
+```c++
+MACRO(Tc(Period), Tc(Spacebar), Tr(OSM(LeftShift)))
+```
+
+...because OneShot will ignore the `INJECTED` event.  One solution is to change
+the value of `event.key`, turning the pressed Macros key into a OneShot
+modifier. This will only work if Macros is registered before OneShot in
+`KALEIDOSCOPE_INIT_PLUGINS()`:
+
+```c++
+const macro_t* macroNewSentence(KeyEvent &event) {
+  if (keyToggledOn(event.state)) {
+    event.key = OSM(LeftShift);
+    return MACRO(Tc(Period), Tc(Spacebar));
+  }
+  return MACRO_NONE;
+}
+```
+
+A more robust solution is to explicitly call `Runtime.handleKeyEvent()`, but
+this is more complex, because you'll need to prevent the Macros key from
+clobbering the OneShot key in the `live_keys[]` array:
+
+```c++
+void macroNewSentence(KeyEvent &event) {
+  if (keyToggledOn(event.state)) {
+    Macros.tap(Key_Period);
+    Macros.tap(Key_Spacebar);
+    event.key = OSM(LeftShift);
+    kaleidoscope::Runtime.handleKeyEvent(event);
+    // Last, we invalidate the current event's key address to prevent the Macros
+    // key value from clobbering the OneShot shift.
+    event.key = Key_NoKey;
+    event.addr.clear();
+  }
+}
+```

+`kaleidoscope-builder` has been removed.

+We replaced it with a new Makefile based build system that uses `arduino-cli` instead of of the full Arduino IDE. This means that you can now check out development copies of Kaliedoscope into any directory, using the `KALEIDOSCOPE_DIR` environment variable to point to your installation.

 ### OneShot meta keys
 
 The special OneShot keys `OneShot_MetaStickyKey` & `OneShot_ActiveStickyKey` are no longer handled by the OneShot plugin directly, but instead by a separate OneShotMetaKeys plugin. If you use these keys in your sketch, you will need to add the new plugin, and register it after OneShot in `KALEIDOSCOPE_INIT_PLUGINS()` for those keys to work properly.

-### Live Composite Keymap Cache
+# Removed APIs
 
-The live composite keymap, which contained a lazily-updated version of the current keymap, has been replaced. The `Layer.updateLiveCompositeKeymap()` functions have been deprecated, and depending on the purpose of the caller, it might be appropriate to use `live_keys.activate()` instead.
+### Removed on 2022-03-03
 
-When `handleKeyswitchEvent()` is looking up a `Key` value for an event, it first checks the value in the active keys cache before calling `Layer.lookup()` to get the value from the keymap. In the vast majority of cases, it won't be necessary to call `live_keys.activate()` manually, however, because simply changing the value of the `Key` parameter of an `onKeyswitchEvent()` handler will have the same effect.
+#### Pre-`KeyEvent` event handler hooks
 
-Second, the `Layer.eventHandler()` function has been deprecated. There wasn't much need for this to be available to plugins, and it's possible to call `Layer.handleKeymapKeyswitchEvent()` directly instead.
+The old event handler `onKeyswitchEvent(Key &key, KeyAddr addr, uint8_t state)` was removed on **2022-03-03**.  It has been replaced with the new `onKeyEvent(KeyEvent &event)` handler (and, in some special cases the `onKeyswitchEvent(KeyEvent &event)` handler).  Plugins using the deprecated handler will need to be rewritten to use the new one(s).
 
-# Removed APIs
+The old event handler `beforeReportingState()` was removed on **2022-03-03**.  It has been replaced with the new `beforeReportingState(KeyEvent &event)` handler.  However, the new handler will be called only when a report is being sent (generally in response to a key event), not every cycle, like the old one.  It was common practice in the past for plugins to rely on `beforeReportingState()` being called every cycle, so when adapting to the `KeyEvent` API, it's important to check for code that should be moved to `afterEachCycle()` instead.
+
+#### `::handleKeyswitchEvent(Key key, KeyAddr key_addr, uint8_t state)`
+
+The old master function for processing key "events" was removed on **2022-03-03**.  Functions that were calling this function should be rewritten to call `kaleidoscope::Runtime.handleKeyEvent(KeyEvent event)` instead.
+
+#### `Keyboard::pressKey(Key key, bool toggled_on)`
+
+This deprecated function was removed on **2022-03-03**.  Its purpose was to handle rollover events for keys that include modifier flags, and that handling is now done elsewhere.  Any code that called it should now simply call `Keyboard::pressKey(Key key)` instead, dropping the second argument.
+
+#### Old layer key event handler functions
+
+The deprecated `Layer.handleKeymapKeyswitchEvent()` function was removed on **2022-03-03**.  Any code that called it should now call `Layer.handleLayerKeyEvent()` instead, with `event.addr` set to the appropriate `KeyAddr` value if possible, and `KeyAddr::none()` otherwise.
+
+The deprecated `Layer.eventHandler(key, addr, state)` function was removed on **2022-03-03**.  Any code that refers to it should now call call `handleLayerKeyEvent(KeyEvent(addr, state, key))` instead.
+
+#### Keymap cache functions
+
+The deprecated `Layer.updateLiveCompositeKeymap()` function was removed on **2022-03-03**.  Plugin and user code probably shouldn't have been calling this directly, so there's no direct replacement for it.  If a plugin needs to make changes to the `live_keys` structure (equivalent in some circumstances to the old "live composite keymap"), it can call `live_keys.activate(addr, key)`, but there are probably better ways to accomplish this goal (e.g. simply changing the value of `event.key` from an `onKeyEvent(event)` handler).
+
+The deprecated `Layer.lookup(addr)` function was removed on **2022-03-03**.  Please use `Runtime.lookupKey(addr)` instead in most circumstances.  Alternatively, if you need information about the current state of the keymap regardless of any currently active keys (which may have values that override the keymap), use `Layer.lookupOnActiveLayer(addr)` instead.

+#### `LEDControl.syncDelay` configuration variable
+
+Direct access to this configuration variable was removed on **2022-03-03**.  Please use `LEDControl.setInterval()` to set the interval between LED updates instead.

+
+The deprecated `Macros.active_macros[]` array was removed on **2022-03-03**.  Any references to it are obsolete, and can simply be removed.

+
+Support for deprecated form of the `macroAction(uint8_t macro_id, uint8_t key_state)` function was removed on **2022-03-03**.  This old form must be replaced with the new `macroAction(uint8_t macro_id, KeyEvent &event)` for macros to continue working.
+
+The `Macros.key_addr` public variable was removed on **2022-03-03**.  To get access to the key address of a Macros key event, simply refer to `event.addr` from within the new `macroAction(macro_id, event)` function.
+
+The deprecated `MACRODOWN()` preprocessor macro was removed on **2022-03-03**.  Since most macros are meant to be triggered only by keypress events (not key release), and because `macroAction()` does not get called every cycle for held keys, it's better to simply do one test for `keyToggledOn(event.state)` first, then use `MACRO()` instead.
+
+#### ActiveModColor public variables
+
+The following deprecated `ActiveModColorEffect` public variables were removed on **2022-03-03**.  Please use the following methods instead:
+
+ - For `ActiveModColor.highlight_color`, use `ActiveModColor.setHighlightColor(color)`
+ - For `ActiveModColor.oneshot_color`, use `ActiveModColor.setOneShotColor(color)`
+ - For `ActiveModColor.sticky_color`, use `ActiveModColor.setStickyColor(color)`

+
+ - For `OneShot.time_out`, use `OneShot.setTimeout(ms)`
+ - For `OneShot.hold_time_out`, use `OneShot.setHoldTimeout(ms)`
+ - For `OneShot.double_tap_time_out`, use `OneShot.setDoubleTapTimeout(ms)`
+
+#### Deprecated OneShot API functions
+
+OneShot was completely rewritten in early 2021, and now is based on `KeyAddr` values (as if it keeps physical keys pressed) rather than `Key` values (with no corresponding physical key location).  This allows it to operate on any `Key` value, not just modifiers and layer shifts.
+
+The deprecated `OneShot.inject(key, key_state)` function was removed on **2022-03-03**.  Its use was very strongly discouraged, and is now unavailable.  See below for alternatives.
+
+The deprecated `OneShot.isActive(key)` function was removed on **2022-03-03**.  There is a somewhat equivalent `OneShot.isActive(KeyAddr addr)` function to use when the address of a key that might be currently held active by OneShot is known.  Any code that needs information about active keys is better served by not querying OneShot specifically.
+
+The deprecated `OneShot.isSticky(key)` function was removed on **2022-03-03**.  There is a somewhat equivalent `OneShot.isStick(KeyAddr addr)` function to use when the address of a key that may be in the one-shot sticky state is known.
+
+The deprecated `OneShot.isPressed()` function was removed on **2022-03-03**.  It was already devoid of functionality, and references to it can be safely removed.
+
+The deprecated `OneShot.isModifierActive(key)` function was removed on **2022-03-03**.  OneShot modifiers are now indistinguishable from other modifier keys, so it is better for client code to do a more general search of `live_keys` or to use another mechanism for tracking this state.
+
+#### `HostPowerManagement.enableWakeup()`
+
+This deprecated function was removed on **2022-03-03**.  The firmware now supports wakeup by default, so any references to it can be safely removed.
+
+#### `EEPROMSettings.version(uint8_t version)`
+
+This deprecated function was removed on **2022-03-03**.  The information stored is not longer intended for user code to set, but instead is used internally.
+
+#### Model01-TestMode plugin

 It is important to know that functions are not always inlined even if they are declared as such; for example, virtual and recursive functions are not normally inlined. Usually recursive functions should not be inline. The main reason for making a virtual function inline is to place its definition in the class, either for convenience or to document its behavior, e.g., for accessors and mutators.

+> Use standard order for readability and to avoid hidden dependencies:
+> - The header associated with this source file, if any
+> - System headers and Arduino library headers (including other Kaleidoscope plugins, but not Kaleidoscope itself)
+> - Kaleidoscope headers and headers for the individual plugin (other than the associated header above)
 
-> Use standard order for readability and to avoid hidden dependencies: Related header, Arduino libraries, other libraries' `.h`, your project's `.h`.
+These three sections should be separated by single blank lines, and should be sorted alphabetically.
 
-All libraries must have at least one header in their top-level `src/` directory, to be included without any path components. This is the way Arduino finds libraries, and a limitation we must adhere to. These headers should - in general - include any other headers they may need, so that the consumer of the library only has to include one header. The name of this header must be the same as the name of the library.
+When including system headers and Arduino library headers (including Kaleidoscope plugins), use angle brackets to indicate that those sources are external.
+
+For headers inside the current library and for Kaleidoscope core headers, use double quotes and a full pathname (starting below the `src/` directory).  This applies to the source file's associated header, as well; don't use a pathname relative to the source file's directory.
 
-The recommended naming is to prefix the library name with `Kaleidoscope-`.
+For the sake of clarity, the above sections can be further divided to make it clear where each included header file can be found, but this is probably not necessary in most cases, because the path name of a header usually indicates which library it is located in.
 
-If there is more than one header, they should be listed as descendants of the project's source directory without use of UNIX directory shortcuts `.` (the current directory) or `..` (the parent directory), and live in a `Kaleidoscope` subdirectory. For example, if we have a plugin named `Kaleidoscope-Something`, which has an additional header file other than `Kaleidoscope-Something.h`, it should be in `src/Kaleidoscope/Something-Other.h`, and be included as:
+For example, the includes in `Kaleidoscope-Something/src/kaleidoscope/Something.cpp` might look like this:

-#include "Kaleidoscope/Something-Other.h"
+
+#include <Arduino.h>

+
+#include "kaleidoscope/KeyAddr.h"
+#include "kaleidoscope/KeyEvent.h"
+#include "kaleidoscope/key_defs.h"
+#include "kaleidoscope/plugin/something/utils.h"
 ```
 
-Having more than one level of subdirectories is not recommended.
+**Exception**
 
-In `dir/foo.cpp` or `dir/foo_test.cpp`, whose main purpose is to implement or test the stuff in `dir2/foo2.h`, order your includes as follows:
+Sometimes, system-specific code needs conditional includes. Such code can put conditional includes after other includes. Of course, keep your system-specific code small and localized. Example:
 
-1. `dir2/foo2.h`
+```c++
-2. Arduino libraries.
+#if defined(ARDUINO_AVR_MODEL01)
-3. Other libraries' `.h` files.
+#include "kaleidoscope/Something-AVR-Model01.h"
-4. Your project's `.h` files.
+#endif
 
-With the preferred ordering, if `dir2/foo2.h` omits any necessary includes, the build of `dir/foo.cpp` or `dir/foo_test.cpp` will break. Thus, this rule ensures that build breakages show up first for the people working on these files, not for innocent people in other packages.
+#if defined(ARDUINO_AVR_SHORTCUT)
+#include "kaleidoscope/Something-AVR-Shortcut.h"
+#endif
+```
 
-`dir/foo.cc` and `dir2/foo2.h` are usually in the same directory (e.g. `Kaleidoscope/Something_test.cpp` and `Kaleidoscope/Something.h`), but may sometimes be in different directories too.
+### Top-level Arduinio Library Headers
 
-Within each section the includes should be ordered alphabetically.
+All libraries must have at least one header in their top-level `src/` directory, to be included without any path components. This is the way Arduino finds libraries, and a limitation we must adhere to. These headers should - in general - include any other headers they may need, so that the consumer of the library only has to include one header. The name of this header must be the same as the name of the library.
 
-You should include all the headers that define the symbols you rely upon, except in the unusual case of [forward declarations](#forward-declarations). If you rely on symbols from `bar.h`, don't count on the fact that you included `foo.h` which (currently) includes `bar.h`: include `bar.h` yourself, unless `foo.h` explicitly demonstrates its intent to provide you the symbols of `bar.h`. However, any includes present in the related header do not need to be included again in the related `cc` (i.e., `foo.cc` can rely on `foo.h`'s includes).
+The naming convention for Kaleidoscope plugins is to use the `Kaleidoscope-` prefix: e.g. `Kaleidoscope-Something`, which would have a top-level header named `Kaleidoscope-Something.h` in its `src/` directory.
 
-For example, the includes in `Kaleidoscope-Something/src/Kaleidoscope/Something.cpp` might look like this:
+In the case of Kaleidoscope plugin libraries, the number of source and header files tends to be very small (usually just one `*.cpp` file and its associated header, in addition to the library's top-level header).  When one plugin depends on another, we therefore only include the top-level header of the dependency.  For example, if `Kaleidoscope-OtherThing` depends on `Kaleidoscope-Something`, the file `kaleidoscope/plugin/OtherThing.h` will contain the line:
 
 ```c++
-#include "Kaleidoscope/Something.h"
+#include <Kaleidoscope-Something.h>
+```
 
-#include "Arduino.h"
+…and `Kaleidoscope-Something.h` will look like this:
 
-#include "Kaleidoscope-LEDControl.h"
+```c++
-#include "Kaleidoscope-Focus.h"
+#include "kaleidoscope/plugin/Something.h"
 ```
 
-**Exception**
+This both makes it clearer where to find the included code, and allows the restructuring of that code without breaking the dependent library (assuming the symbols haven't changed as well).
 
-Sometimes, system-specific code needs conditional includes. Such code can put conditional includes after other includes. Of course, keep your system-specific code small and localized. Example:
+If a plugin library has symbols meant to be exported, and more than one header file in which those symbols are defined, all such header files should be included in the top-level header for the library.  For example, if `Kaleidoscope-Something` defines types `kaleidoscope::plugin::Something` and `kaleidoscope::plugin::something::Helper`, both of which are meant to be accessible by `Kaleidoscope-OtherThing`, the top-level header `Kaleidoscope-Something.h` should look like this:
 
 ```c++
-#include "Kaleidoscope.h"
+#include "kaleidoscope/plugin/Something.h"
+#include "kaleidoscope/plugin/something/Helper.h"
+```
 
-#if defined(ARDUINO_AVR_MODEL01)
+### Automated header includes checking
-#include "Kaleidoscope/Something-AVR-Model01.h"
-#endif
 
-#if defined(ARDUINO_AVR_SHORTCUT)
+We have an automated wrapper for the `include-what-you-use` program from LLVM that processes most Kaleidoscope source files and updates their header includes to comply with the style guide.  It requires at least version 0.18 of `include-what-you-use` in order to function properly (because earlier versions do not return a useful exit code, so determining if there was an error was difficult).  It can be run by using the `make check-includes` target in the Kaleidoscope Makefile.

+Kaleidoscope uses some automated tools to enforce compliance with this code style guide.  Primarily, we use `clang-format` to format source files, `cpplint` to check for potential problems, and `include-what-you-use` to update header includes.

+We use `clang-format`(version 12 or higher) to automatically format Kaleidoscope source files.  There is a top-level `.clang-format` config file that contains the settings that best match the style described in this guide.

+By default, `format-code.py` will first check for unstaged changes in the Kaleidoscope git working tree, and exit before formatting source files if any are found.  This is meant to make it easier for developers to see the changes made by the formatter in isolation.  It can be given the `--force` option to skip this check.
+
+It also has a `--check` option, which will cause `format-code.py` to check for unstaged git working tree changes after running `clang-format` on the target source files, and return an error code if there are any, allowing us to automatically verify that code submitted complies with the formatting rules.
+
+The easiest way to invoke the formatter on the whole repository is by running `make format` at the top level of the Kaleidoscope repository.
+
+For automated checking of PRs in a CI tool, there is also `make check-code-style`.
+
+### Linting
+
+We use a copy of `cpplint.py` (with a modification that allows us to set the config file) to check for potential problems in the code.  This can be invoked by running `make cpplint` at the top level of the Kaleidoscope repository.
+
+### Header Includes
+
+We use `include-what-you-use` (version 18 or higher) to automatically manage header includes in Kaleidoscope source files.  Because of the peculiarities of Kaleidoscope's build system, we use a wrapper script, `iwyu.py`, instead of invoking it directly.
+
+`iwyu.py` takes a list of target filenames, either as command-line parameters or from standard input (if reading from a pipe, with each line treated as a filename), and makes changes to the header includes.  If given a directory target, it will recursively search that directory for source files, and run `include-what-you-use` on all of the ones it finds.
+
+A number of files can't be processed this way, and are enumerated in `.iwyu_ignore`.  Files in the `testing` directory (for the test simulator) require different include path items, so cannot be combined in the same call to `iwyu.py`.
+
+The easiest way to invoke `iwyu.py` is by running `make check-includes`, which will check all files that differ between the git working tree and the current master branch of the main Kaleidoscope repository, update their headers, and return a non-zero exit code if there were any errors processing the file(s) or any changes made.
+
+For automated checking of header includes in a CI tool, there is also `make check-all-includes`, that checks the whole repository, not just the current branch's changes.

-## Creating artificial events
+## Creating additional events
 
-## Controlling LEDs
+Another thing we might want a plugin to do is generate "extra" events that don't correspond to physical state changes.  An example of this is the Macros plugin, which might turn a single keypress into a series of HID reports sent to the host.  Let's build a simple plugin to illustrate how this is done, by making a key type a string of characters, rather than a single one.
 
-## HID reports
+For the sake of simplicity, let's make the key `H` result in the string `Hi!` being typed (from the point of view of the host computer).  To do this, we'll make a plugin with an `onKeyEvent()` handler (because we want it to respond to a particular keypress event), which will call `Runtime.handleKeyEvent()` to generate new events sent to the host.
+
+The first thing we need to understand to do this is how to use the `KeyEvent()` constructor to create a new `KeyEvent` object.  For example:
+
+```c++
+KeyEvent event = KeyEvent(KeyAddr::none(), IS_PRESSED, Key_H);
+```
+
+This creates a `KeyEvent` where `event.addr` is an invalid address that doesn't correspond to a physical keyswitch, `event.state` has only the `IS_PRESSED` bit set, but not `WAS_PRESSED`, which corresponds to a key toggle-on event, and `event.key` is set to `Key_H`.
+
+We can then cause Kaleidoscope to process this event, including calling plugin handlers, by calling `Runtime.handleKeyEvent(event)`:
+
+```c++
+  EventHandlerResult onKeyEvent(KeyEvent &event) {
+    if (event.key == Key_H && keyToggledOn(event.state)) {
+
+      // Create and send the `H` (shift + h)
+      KeyEvent new_event = KeyEvent(KeyAddr::none(), IS_PRESSED, LSHIFT(Key_H));
+      Runtime.handleKeyEvent(new_event);
+
+      // Change the key value and send `i`
+      new_event.key = Key_I;
+      Runtime.handleKeyEvent(new_event);
+
+      // Change the key value and send `!` (shift + 1)
+      new_event.key = LSHIFT(Key_1);
+      Runtime.handleKeyEvent(new_event);
+
+      return EventHandlerResult::ABORT;
+    }
+    return EventHandlerResult::OK;
+  }
+```
+
+A few shortcuts were taken with this plugin that are worth pointing out.  First, you may have noticed that we didn't send any key _release_ events, just three presses.  This works, but there's a small chance that it could cause problems for some plugin that's trying to match key presses and releases.  To be nice (or pedantic, if you will), we could also send the matching release events, but this is probably not necessary in this case, because we've used an invalid key address (`KeyAddr::none()`) for these generated events.  This means that Kaleidoscope will not be recording these events as held keys.  If we had used valid key addresses (corresponding to physical keyswitches) instead, it would be more important to send matching release events to keep keys from getting "stuck" on.  For example, we could just use the address of the `H` key that was pressed:
+
+```c++
+  EventHandlerResult onKeyEvent(KeyEvent &event) {
+    if (event.key == Key_H && keyToggledOn(event.state)) {
+
+      KeyEvent new_event = KeyEvent(event.addr, IS_PRESSED, LSHIFT(Key_H));
+      Runtime.handleKeyEvent(new_event);
+
+      new_event.key = Key_I;
+      Runtime.handleKeyEvent(new_event);
+
+      new_event.key = LSHIFT(Key_1);
+      Runtime.handleKeyEvent(new_event);
+
+      return EventHandlerResult::ABORT;
+    }
+    return EventHandlerResult::OK;
+  }
+```
+
+This new version has the curious property that if the `H` key is held long enough, it will result in repeating `!!!!` characters on the host, until the key is released, which will clear it.  In fact, instead of creating a whole new `KeyEvent` object, we could further simplify this plugin by simply modifying the `event` object that we already have, instead:
+
+```c++
+  EventHandlerResult onKeyEvent(KeyEvent &event) {
+    if (event.key == Key_H && keyToggledOn(event.state)) {
+      event.key = LSHIFT(Key_H);
+      Runtime.handleKeyEvent(event);
+
+      event.key = Key_I;
+      Runtime.handleKeyEvent(event);
+
+      event.key = LSHIFT(Key_1);
+    }
+    return EventHandlerResult::OK;
+  }
+```
+
+Note that, with this version, we've only sent two extra events, then changed the `event.key` value, and returned `OK` instead of `ABORT`.  This is basically the same as the above pluging that turned `Y` into `X`, but with two extra events sent first.
+
+As one extra precaution, it would be wise to mark the generated event(s) as "injected" to let other plugins know that these events should be ignored.  This is a convention that is used by many existing Kaleidoscope plugins.  We do this by setting the `INJECTED` bit in the `event.state` variable:
+
+```c++
+  EventHandlerResult onKeyEvent(KeyEvent &event) {
+    if (event.key == Key_H && keyToggledOn(event.state)) {
+      event.state |= INJECTED;
+
+      event.key = LSHIFT(Key_H);
+      Runtime.handleKeyEvent(event);
+
+      event.key = Key_I;
+      Runtime.handleKeyEvent(event);
+
+      event.key = LSHIFT(Key_1);
+    }
+    return EventHandlerResult::OK;
+  }
+```
+
+If we wanted to be especially careful, we could also add the corresponding release events:
+
+```c++
+  EventHandlerResult onKeyEvent(KeyEvent &event) {
+    if (event.key == Key_H && keyToggledOn(event.state)) {
+      event.key = LSHIFT(Key_H);
+      event.state = INJECTED | IS_PRESSED;
+      Runtime.handleKeyEvent(event);
+      event.state = INJECTED | WAS_PRESSED;
+      Runtime.handleKeyEvent(event);
+
+      event.key = Key_I;
+      event.state = INJECTED | IS_PRESSED;
+      Runtime.handleKeyEvent(event);
+      event.state = INJECTED | WAS_PRESSED;
+      Runtime.handleKeyEvent(event);
+
+      event.key = LSHIFT(Key_1);
+      event.state = INJECTED | IS_PRESSED;
+    }
+    return EventHandlerResult::OK;
+  }
+```
+
+### Avoiding infinite loops
+
+One very important consideration for any plugin that calls `Runtime.handleKeyEvent()` from an `onKeyEvent()` handler is recursion.  `Runtime.handleKeyEvent()` will call all plugins' `onKeyEvent()` handlers, including the one that generated the event.  Therefore, we need to take some measures to short-circuit the resulting recursive call so that our plugin doesn't cause an infinite loop.
+
+Suppose the example plugin above was changed to type the string `hi!` instead of `Hi!`.  When sending the first generated event, with `event.key` set to `Key_H`, our plugin would recognize that event as one that should be acted on, and make another call to `Runtime.handleKeyEvent()`, which would again call `MyPlugin.onKeyEvent()`, and so on until the MCU ran out of memory on the stack.
+
+The simplest mechanism used by many plugins that mark their generated events "injected" is to simply ignore all generated events:
+
+```c++
+  EventHandlerResult onKeyEvent(KeyEvent &event) {
+    if ((event.state & INJECTED) != 0)
+      return EventHandlerResult::OK;
+
+    if (event.key == Key_H && keyToggledOn(event.state)) {
+      event.state |= INJECTED;
+
+      event.key = LSHIFT(Key_H);
+      Runtime.handleKeyEvent(event);
+
+      event.key = Key_I;
+      Runtime.handleKeyEvent(event);
+
+      event.key = LSHIFT(Key_1);
+    }
+    return EventHandlerResult::OK;
+  }
+```
+
+There are other techniques to avoid inifinite loops, employed by plugins whose injected events should be processed by other plugins, but since most of those will be using the `onKeyswitchEvent()` handler instead of `onKeyEvent()`, we'll cover that later in this guide.
 
 ## Physical keyswitch events
 
+Most plugins that respond to key events can do their work using the `onKeyEvent()` handler, but in some cases, it's necessary to use the `onKeyswitchEvent()` handler instead.  These event handlers are strictly intended for physical keyswitch events, and plugins that implement the `onKeyswitchEvent()` handler must abide by certain rules in order to work well with each other.  As a result, such a plugin is a bit more complex, but there are helper mechanisms to make things easier:
+
+```c++
+#include "kaleidoscope/KeyEventTracker.h"
+
+namespace kaleidoscope {
+namespace plugin {
+
+class MyKeyswitchPlugin : public Plugin {
+ public:
+  EventHandlerResult onKeyswitchEvent(KeyEvent &event) {
+    if (event_tracker_.shouldIgnore(event))
+      return EventHandlerResult::OK;
+    // Plugin logic goes here...
+    return EventHandlerResult::OK;
+  }
+ private:
+  KeyEventTracker event_tracker_;
+};
+
+} // namespace kaleidoscope
+} // namespace plugin
+
+kaleidoscope::plugin::MyKeyswitchPlugin;
+```
+
+We've just added a `KeyEventTracker` object to our plugin, and made the first line of its `onKeyswitchEvent()` handler call that event tracker's `shouldIgnore()` method, returning `OK` if it returns `true` (thereby ignoring the event).  Every plugin that implements `onKeyswitchEvent()` should follow this template to avoid plugin interaction bugs, including possible infinite loops.
+
+The main reason for this event tracker mechanism is that plugins with `onKeyswitchEvent()` handlers often delay events because some aspect of those events (usually `event.key`) needs to be determined by subsequent events or timeouts.  To do this, event information is stored, and the event is later regenerated by the plugin, which calls `Runtime.handleKeyswitchEvent()` so that the other `onKeyswitchEvent()` handlers can process it.
+
+We need to prevent infinite loops, but simply marking the regenerated event `INJECTED` is no good, because it would prevent the other plugins from acting on it, so we instead keep track of a monotonically increasing event id number and use the `KeyEventTracker` helper class to ignore events that our plugin has already recieved, so that when the plugin regenerates an event with the same event id, it (and all the plugins before it) can ignore that event, but the subsequent plugins, which haven't seen that event yet, will recongize it as new and process the event accordingly.
+
+### Regenerating stored events
+
+When a plugin that implements `onKeyswitchEvent()` regenerates a stored event later so that it can be processed by the next plugin in the chain, it must use the correct event id value (the same one used by the original event).  This is an object of type `EventId`, and is retrieved by calling `event.id()` (unlike the other properties of a `KeyEvent` object the event id is not directly accessible).
+
+```c++
+KeyEventId stored_id = event.id();
+```
+
+When reconstructing an event to allow it to proceed, we then use the four-argument version of the `KeyEvent` constructor:
+
+```c++
+KeyEvent event = KeyEvent(addr, state, key, stored_id);
+```
+
+In the above, `addr` and `state` are usually also the same as the original event's values, and `key` is most often the thing that changes.  If your plugin wants a keymap lookup to take place, the value `Key_Undefined` can be used instead of explicitly doing the lookup itself.

+/** The Model 01's key layouts are defined as 'keymaps'. By default, there are three
+  * keymaps: The standard QWERTY keymap, the "Function layer" keymap and the "Numpad"
+  * keymap.
+  *
+  * Each keymap is defined as a list using the 'KEYMAP_STACKED' macro, built
+  * of first the left hand's layout, followed by the right hand's layout.
+  *
+  * Keymaps typically consist mostly of `Key_` definitions. There are many, many keys
+  * defined as part of the USB HID Keyboard specification. You can find the names
+  * (if not yet the explanations) for all the standard `Key_` defintions offered by
+  * Kaleidoscope in these files:
+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/kaleidoscope/key_defs_keyboard.h
+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/kaleidoscope/key_defs_consumerctl.h

+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/kaleidoscope/key_defs_keymaps.h
+  *
+  * Additional things that should be documented here include
+  *   using ___ to let keypresses fall through to the previously active layer
+  *   using XXX to mark a keyswitch as 'blocked' on this layer
+  *   using ShiftToLayer() and LockLayer() keys to change the active keymap.
+  *   keeping NUM and FN consistent and accessible on all layers
+  *
+  * The PROG key is special, since it is how you indicate to the board that you
+  * want to flash the firmware. However, it can be remapped to a regular key.
+  * When the keyboard boots, it first looks to see whether the PROG key is held
+  * down; if it is, it simply awaits further flashing instructions. If it is
+  * not, it continues loading the rest of the firmware and the keyboard
+  * functions normally, with whatever binding you have set to PROG. More detail
+  * here: https://community.keyboard.io/t/how-the-prog-key-gets-you-into-the-bootloader/506/8
+  *
+  * The "keymaps" data structure is a list of the keymaps compiled into the firmware.
+  * The order of keymaps in the list is important, as the ShiftToLayer(#) and LockLayer(#)
+  * macros switch to key layers based on this list.
+  *
+  *
+
+  * A key defined as 'ShiftToLayer(FUNCTION)' will switch to FUNCTION while held.
+  * Similarly, a key defined as 'LockLayer(NUMPAD)' will switch to NUMPAD when tapped.

+  * keymap.
+  *
+  * Each keymap is defined as a list using the 'KEYMAP_STACKED' macro, built
+  * of first the left hand's layout, followed by the right hand's layout.
+  *
+  * Keymaps typically consist mostly of `Key_` definitions. There are many, many keys
+  * defined as part of the USB HID Keyboard specification. You can find the names
+  * (if not yet the explanations) for all the standard `Key_` defintions offered by
+  * Kaleidoscope in these files:
+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/kaleidoscope/key_defs/keyboard.h

+  * Additional things that should be documented here include
+  *   using ___ to let keypresses fall through to the previously active layer
+  *   using XXX to mark a keyswitch as 'blocked' on this layer
+  *   using ShiftToLayer() and LockLayer() keys to change the active keymap.
+  *   keeping NUM and FN consistent and accessible on all layers
+  *
+  * The PROG key is special, since it is how you indicate to the board that you
+  * want to flash the firmware. However, it can be remapped to a regular key.
+  * When the keyboard boots, it first looks to see whether the PROG key is held
+  * down; if it is, it simply awaits further flashing instructions. If it is
+  * not, it continues loading the rest of the firmware and the keyboard
+  * functions normally, with whatever binding you have set to PROG. More detail
+  * here: https://community.keyboard.io/t/how-the-prog-key-gets-you-into-the-bootloader/506/8
+  *
+  * The "keymaps" data structure is a list of the keymaps compiled into the firmware.
+  * The order of keymaps in the list is important, as the ShiftToLayer(#) and LockLayer(#)
+  * macros switch to key layers based on this list.
+  *
+  *
+
+  * A key defined as 'ShiftToLayer(FUNCTION)' will switch to FUNCTION while held.
+  * Similarly, a key defined as 'LockLayer(NUMPAD)' will switch to NUMPAD when tapped.
