Precomposed Greek Letters with Psili Accent

[anaskaejdar]

Allo! 👋 I'm sorry it took me so long to start putting these together. Work has kept me very busy. Anyway, I'll create different tickets for the different accent marks, so this one is specifically for the psili accent. Psili has pretty much the same shape as the latin comma, except it floats above a letter to indicate "smooth breathing" in older forms of the greek language.

If there's an accent toggle on the keyboard, which, when activated, replaces the letters with same letter, except precomposed with the psili over it, it would be like this:

Activate psili diacritic:
α ⇒ ἀ
ὰ ⇒ ἂ
ά ⇒ ἄ
ά ⇒ ἄ
ᾶ ⇒ ἆ
Α ⇒ Ἀ
Ὰ ⇒ Ἂ
Ά ⇒ Ἄ
Ά ⇒ Ἄ
**[No precomposed Α͂] ⇒ Ἆ
ε ⇒ ἐ
ὲ ⇒ ἒ
έ ⇒ ἔ
έ ⇒ ἔ
Ε ⇒ Ἐ
Ὲ ⇒ Ἒ
Έ ⇒ Ἔ
Έ ⇒ Ἔ
η ⇒ ἠ
ὴ ⇒ ἢ
ή ⇒ ἤ
ή ⇒ ἤ
ῆ ⇒ ἦ
Η ⇒ Ἠ
Ὴ ⇒ Ἢ
Ή ⇒ Ἤ
Ή ⇒ Ἤ
**[No precomposed Η͂] ⇒ Ἦ
ι ⇒ ἰ
ὶ ⇒ ἲ
ί ⇒ ἴ
ί ⇒ ἴ
ῖ ⇒ ἶ
Ι ⇒ Ἰ
Ὶ ⇒ Ἲ
Ί ⇒ Ἴ
Ί ⇒ Ἴ
**[No precomposed Ι͂] ⇒ Ἶ
ο ⇒ ὀ
ὸ ⇒ ὂ
ό ⇒ ὄ
ό ⇒ ὄ
Ο ⇒ Ὀ
Ὸ ⇒ Ὂ
Ό ⇒ Ὄ
Ό ⇒ Ὄ
υ ⇒ ὐ
ὺ ⇒ ὒ
ύ ⇒ ὔ
ύ ⇒ ὔ
ῦ ⇒ ὖ
ω ⇒ ὠ
ὼ ⇒ ὢ
ώ ⇒ ὤ
ώ ⇒ ὤ
ῶ ⇒ ὦ
Ω ⇒ Ὠ
Ὼ ⇒ Ὢ
Ώ ⇒ Ὤ
Ώ ⇒ Ὤ
**[No precomposed Ω͂] ⇒ Ὦ
ᾳ ⇒ ᾀ
ᾲ ⇒ ᾂ
ᾴ ⇒ ᾄ
ᾷ ⇒ ᾆ
ᾼ ⇒ ᾈ
**[No precomposed Ὰͅ] ⇒ ᾊ
**[No precomposed Άͅ] ⇒ ᾌ
**[No precomposed ᾼ͂] ⇒ ᾎ
ῃ ⇒ ᾐ
ῂ ⇒ ᾒ
ῄ ⇒ ᾔ
ῇ ⇒ ᾖ
ῌ ⇒ ᾘ
**[No precomposed Ὴͅ] ⇒ ᾚ
**[No precomposed Ήͅ] ⇒ ᾜ
**[No precomposed ῌ͂] ⇒ ᾞ
ῳ ⇒ ᾠ
ῲ ⇒ ᾢ
ῴ ⇒ ᾤ
ῷ ⇒ ᾦ
ῼ ⇒ ᾨ
**[No precomposed Ὼͅ] ⇒ ᾪ
**[No precomposed Ώͅ] ⇒ ᾬ
**[No precomposed ῼ͂] ⇒ ᾮ
ρ ⇒ ῤ
[space character maybe (what's your opinion?)] ⇒ ᾿
` ⇒ ῍
` ⇒ ῍
´ ⇒ ῎
´ ⇒ ῎
῀ ⇒ ῏
~ ⇒ ῏

** These items don't have a simple starting character that would be replaced with a psili version. The psili version has a precomposed character. But basically, the greek-extended unicode block is missing some combinations. Some letters simply don't have precomposed accented forms without breathing marks. So I don't know how you'd want to accomplish this technically, but somehow, if all four are activated at the same time --- psili mark, vareia accent, ypogegrammeni subscript, AND shift/caps --- then the Ω key should be replaced with ᾪ for instance, even though there is no precomposed character for the same thing without a psili: Ὼͅ

Thanks for the table! About the lack of accented letters in Unicode, it's currently not possible to have a multi-code-point character on the left of the arrow currently.
But it's possible to make the modifiers be applied in a specified order, for example with both ' and ~ activated, do Α ⇒ Ἀ ⇒ Ἆ instead of Α ⇒ Α͂ ⇒ Ἆ if Α͂ can't be on the left of an arrow.
It's also possible to append a combining diacritic mark to some letters (or all characters on the keyboard) when a modifier is on.

We can force a particular order for the accents? Oh, that's good to hear! I imagined it would just depend on which order the accents were activated in the moment by the user. So let's explore what would be the best order-of-operations for these special cases...

Well, I made a table and everything, but the rule is actually very simple... In these specific cases (**) the Psili just cannot be applied last. Same goes for #763 where in the special cases, the Dasia just cannot be applied last.

For plan B, I wonder if UnexpectedKeyboard at present would be able to deal with some kind of instruction that's basically, if this whole combination of modifiers are all activated together at the same time, then replace this basic char with that heavily-accented one... but if they aren't all activated together, then leave the original char in place. Can the modifiers be aware of one another in this way?

For plan C, I guess the logic could be something like, this letter cannot have oxeia(/vareia/perispomeni) without also having either psili or dasia, so let's just assume it's psili, and then if the user wanted dasia instead, he/she could just activate that modifier. This feels dirtier, but it'd be fine and practical
