#include QMK_KEYBOARD_H
[Keymap] Redo the accent implementation in melody96:zunger. (#11000) The previous implementation generated accents in NFKD -- e.g., i followed by fn+e would generate í, which is actually an ordinary i followed by U+0301 COMBINING ACUTE ACCENT. Unfortunately, it turns out that a bunch of websites and apps (especially European ones written in languages that use these a lot) were very poorly written, and will misparse and/or crash if presented with Unicode NFKD. They require and expect NFKC, with characters like í (U+00ED LATIN SMALL I WITH ACUTE) that look visually identical -- and are in fact normalization-equivalent -- but have to be encoded differently. The new accent implementation handles this in a very flexible way. Many new comments added as well, as it's also clear that this is going to need a bit more expansion before it becomes a true polyglot keymap. Co-authored-by: Yonatan Zunger <zunger@desiderata.lan>

#include <assert.h>
// This keymap is designed to make it easy to type in a wide variety of languages, as well as
// generate mathematical symbols (à la Space Cadet).
//
// LAYER MAGIC (aka, typing in many alphabets)
// This keyboard has three "base" layers: QWERTY, GREEK, and CADET. The GREEK and CADET layers
// are actually full of Unicode points, and so which point they generate depends on things like
// whether the shift key is down. To handle this, each of those layers is actually *two* layers, one
// with and one without shift. In our main loop, we manage modifier state detection, as well as
// layer switch detection, and pick the right layer on the fly.
// Layers are selected with a combination of three keys. The "Greek" and "Cadet" keys act like
// modifiers: When held down, they transiently select the indicated base layer. The "Layer Lock" key
// locks the value of the base layer at whatever is currently held; so e.g., if you hold Greek +
// Layer Lock, you'll stay in Greek mode until you hit Layer Lock again without any of the mods
// held.
// TODO: This system of layer selection is nice for math, but it's not very nice for actually
// typing in multiple languages. It seems like a better plan will be to reserve one key for each
// base layer -- maybe fn + F(n) -- which can either be held as a modifier or tapped to switch
// layers. That will open up adding some more languages, like Yiddish, but to do this effectively
// we'll need to find a good UI with which to show the currently selected layer. Need to check what
// the melody96 has in the way of outputs (LEDs, sound, etc).
//
// ACCENT MAGIC (aka, typing conveniently in Romance languages)
// We want to support easy typing of diacritical marks. We can't rely on the host OS for this,
// because (e.g.) on MacOS, to make any of the other stuff work, we need to be using the Unicode
// input method at the OS level, which breaks all the normal accent stuff on that end. So we do it
// ourselves. Accents can actually be invoked in two different ways: one fast and very compatible,
// one very versatile but with occasional compatibility problems.
//
// THE MAIN WAY: You can hit one of the "accent request" key patterns immediately *before* typing
// a letter to be accented. It will emit the corresponding accented Unicode. For example, you can
// hit fn-e to request an acute accent, followed by i, and it will output í, U+00ED LATIN SMALL
// LETTER I WITH ACUTE. These "combined characters" are in Unicode normal form C (NFKC), which is
// important because many European websites and apps, in particular, tend to behave very badly
// (misunderstanding and/or crashing) when presented with characters in other forms! The catch is
// that this only works for the various combinations of letters and accents found in the Latin-1
// supplement block of Unicode -- basically, things you need for Western European languages.
//
// (NB: If you make an accent request followed by a letter which can't take the corresponding
// accent, it will output the uncombined form of the accent followed by whatever you typed; so
// e.g., if you hit fn-e followed by f, it will output ´f, U+00B4 ACUTE ACCENT followed by an
// ordinary f. This is very similar to the default behavior of MacOS.)
//
// THE FLEXIBLE WAY: If you hit the accent request with a shift -- e.g., fn-shift-e -- it will
// instead immediately output the corresponding *combining* Unicode accent mark, which will modify
// the *previous* character you typed. For example, if you type i followed by fn-shift-e, it will
// generate í. But don't be fooled by visual similarity: unlike the previous example, this one is
// an ordinary i followed by U+0301 COMBINING ACUTE ACCENT. It's actually *two symbols*, and this
// is Unicode normal form D (NFKD). Unlike NFKC, there are NFKD representations of far more
// combinations of letters and accents, and it's easy to add more of these if you need. (The NFKC
// representation of such combinations is identical to their NFKD representation)
//
// Programs that try to compare Unicode strings *should* first normalize them by converting them
// all into one normal form or another, and there are functions in every programming language to
// do this -- e.g., JavaScript's string.normalize() -- but lots of programmers fail to understand
// this, and so write code that massively freaks out when it encounters the wrong form.
//
// The current accent request codes are modeled on the ones in MacOS.
//
// fn+` Grave accent (`)
// fn+e Acute accent (´)
// fn+i Circumflex (^)
// fn+u Diaresis / umlaut / trema (¨)
// fn+c Cedilla (¸)
// fn+n Tilde (˜)
//
// Together, these functions make for a nice "polyglot" keyboard: one that can easily type in a wide
// variety of languages, which is very useful for people who, well, need to type in a bunch of
// languages.
//
// The major TODOs are:
// - Update the layer selection logic (and add visible layer cues);
// - Factor the code below so that the data layers are more clearly separated from the code logic,
// so that other users of this keymap can easily add whichever alphabets they need without
// having to deeply understand the implementation.

// CADET or GREEK+ALT triggers the Cadet (aka "Top") layer, or the SHIFTCADET layer when
// shift is held.
// LAYER_LOCK locks the "base" layer (i.e., QWERTY, GREEK, or CADET) to the value which is
// pressed at the moment that it is being released. When a layer lock is set, the
// analogous layer modifier key is reversed; e.g., if you lock the GREEK layer, then the

// We also parse the shift, alt, and caps lock keys to provide management of those which is
// compatible with these various layers.

// Accent implementation
//
// In the body of process_record_user, we store an "accent_request", which is the accent keycode if
// one was just selected, or zero otherwise. When the *next* key is hit, we look up whether the
// accent request plus that next keycode (plus the state of the shift key) together amount to an
// interesting combined (NFKC) character, and if so, emit it; otherwise, we emit the accent as a
// separate character and then process the next key normally. The resulting UI behavior is similar
// to that of the combining accent keys in MacOS.
//
// We store two arrays, depending on whether shift is or isn't held. Each is two-dimensional, with
// its outer key by the next keycode struck, and the inner key by the accent requested. The outer
// array has KC_Z + 1 as its upper bound, so that we can save memory by only coding alphabetic keys.
// The contents are either Unicode code points, or zero to indicate that we don't have a point for
// this combination.

[Keymap] Redo the accent implementation in melody96:zunger. (#11000) The previous implementation generated accents in NFKD -- e.g., i followed by fn+e would generate í, which is actually an ordinary i followed by U+0301 COMBINING ACUTE ACCENT. Unfortunately, it turns out that a bunch of websites and apps (especially European ones written in languages that use these a lot) were very poorly written, and will misparse and/or crash if presented with Unicode NFKD. They require and expect NFKC, with characters like í (U+00ED LATIN SMALL I WITH ACUTE) that look visually identical -- and are in fact normalization-equivalent -- but have to be encoded differently. The new accent implementation handles this in a very flexible way. Many new comments added as well, as it's also clear that this is going to need a bit more expansion before it becomes a true polyglot keymap. Co-authored-by: Yonatan Zunger <zunger@desiderata.lan>
