Changes for version 0.09

  • Cache results of <any-foo> - speeds up things another 2x, but behaves bad w.r.t. pairing of uc/lc letters. Report resolution of mutator recipes if UI_KEYBOARDLAYOUT_REPORT_MUTATORS is set in environment; bit 0x1 for concise report, bit 0x2 for verbose (to STDOUT!), bit 0x4 for details of sorting compositions, bit 0x8 for composing, bit 0x10 for caching <any-*> compose, bit 0x20 for inhibiting cache-merging <any-*>. Explicit penalization was applied to a Shift-pair of characters even if it is not an lc/uc-pair. Allow partial penalization (via \ú). Extra arguments $omit (not used yet) and $do_lc, $do_uc for shift_pop_composition(). Allow for fallbacks in prefix keys sharing a recipe in opposite direction (after the second ||||). Penalize lists start anew in every ||||- (or top |||-) section. New semantic of repetition on these sections: we do not extract a char already extracted in previous section, but may extract a char mentioned there, but not extracted. New variant of Mutate*(): Mutate32OK[].
  • starting Mutate[]'s directives means "primary recipe"; ||| etc are the same as |. (Now can share the whole primary directives.) Allow -recipe1+recipe2 in a mutator (including <any-foo> in recipe1 - need to switch off caching!). Fix the UP/DOWN TACK mixup in Unicode names. Add version numbers to the coverage report. New coverage lists: IPA-obsolete-and-capital-small and UPA (Uralic PA). Penalization via \ọ was not working on double-occupation slots. Add Cʗ to phonetize. Add uc/lc fixes for Ɋ and ß. Fix IPA-obsolete/etc coverage set (had 2 PUA from WikiPedia page; fix one of them both here and there).
  • izKeys.kbdd: Add `turned' to AltGr-'. Tortoise parens supported (again!), 3 variants of 4, and bold braces. Micro-optimize to the level of 0.01 - only much better. Swap ␠/␢; add symbols for special keys to Shift-Space; add images for special keys to Business; with ↹ on Tab, ⇤ on C-[, ⇥ on C-]; NL and NUL considered as images (on C-Enter and C-\), and CR LF as symbols. Bump the version to 0.02. Optimize IPA coverage "by visual resemblance" (now all symbols except for modifiers/combiners are present); [but broke case-preservation: ɞ/ɝ/ɺ are on upper-case E,È,AltGr-I with AltGr-/]. Swap AltGr-Y/U on Coptic (have exotic Greek letter forms); move Ohm from Business to Coptic, add inverted. Put fi/fl ligatures on AltGr-w/W, and HOUSE ⌂ on AltGr-h on Business.
    • Only graphics + arrows + 9 5-bit C0 dingbats of cp437 not supported from MES-2 now.
      • Add ⌈⌉⌊⌋ to {}[] on AltGr-/ (heuristic: cut off a piece). Try adding double-struck on AltGr-/ (CHN fit, PQRZ not). Penalize ọ to have all of dots below accessible the same way (on AltGr; having them all without AltGr makes Scandinavian å, Turkish ı and Lithuanian ė harder to enter; I presume that Vietnamese input with this layout will not be the prime-time usage). Switch ủ and ǚ and other clean ups. Pinyin ǚ now entered the natural way; Latin-Belorussian/Esperanto ŭ moved to AltGr-/. Business map: move (CJK) Yuans to AltGr-u/U; move schwa case pairs to z/Z (African to AltGr); put hooks on u/o; move c/o to / and AltGr-o, ℮ to AltGr-e; add Double-Female/Male and "Female and Male" signs on AltGr: F/M/a. Add case pair for ʔ on AltGr-?/ on Greek (this finishes "obsolete+case-pairs of IPA"). Add smallcaps Greek and OU on breve + AltGr-Shift (this finishes non-modifiers/combiners of UPA). (This did not cover smallcaps-Γ [not in UPA according to WikiPedia!], so duplicate on grave.) Penalize ⊠ to allow for ???.
  • Vietnamese vowels; input: The vowels with 1 diacritic (except horn and hook above): only ê can be entered via AltGr (as AltGr-e); all may be entered by the corresponding dead key (as AltGr-6/^/`/'/~ for ˘/ˆ/`/´/˜ followed by the base vowel; and AltGr-. AltGr-vowel for the dot-below diacritic). Ư/Ơ: put ` on AltGr-vowel (as AltGr-` AltGr-vowel); or on AltGr-$ map; Ư/Ơ with ` or ´: put ` or ´ on U/O with the opposite tick (´ or `); as AltGr-` (or AltGr-') AltGr-key; here key is one (or two, for ´) keys below the u/o key. Hook above: put ¨ on AltGr-vowel (as AltGr-; AltGr-vowel). (!!! Except ủ: do AltGr-' AltGr-u) Double diacritics involving ê, or `, or ´ (except ê?=ể/ệ and those involving hook above or horn): put the OTHER diacritic on the AltGr-key accessing ê or the vowel with ` or ´. Example: ầ via AltGr-^ AltGr-z (since AltGr-z gives à). Tilde or dot-below on â/ê/ô or ă/ơ/ư: Tap AltGr-~ or AltGr-. and press the corresponding GREEN KEY (replace the ˆ-vowel by `-vowel, and ă/ơ/ư by å/ø/b and use the key accessing the replacement (AltGr-z/AltGr-f/AltGr-m/AltGr-r/AltGr-p/b). Example: AltGr-~ AltGr-z gives ẫ since AltGr-z gives à which is a GREEN KEY for â. Likewise, hook-above on â/ê/ô or ă/ơ/ư: tap AltGr-; then the GREEN key.
    • Symbolic representation of these rules (with diaeresis=AltGr-; ) (the GREEN one is a generalization of grave one above it): grave + diaeresis ==> horn or (same) grave + AltGr ==> horn (or use AltGr-$ prefix) grave + acute ==> grave + horn acute + grave ==> acute + horn diaeresis + AltGr ==> hook above tilde/dot-below + grave ==> tilde/dot-below + hat tilde/dot-below + GREEN ==> tilde/dot-below + horn/hat/breve diaeresis + grave ==> hook-above + hat diaeresis + GREEN ==> hook-above + horn/hat/breve
    • In the shortest form: diaeresis + AltGr ==> hook above diaeresis + GREEN ==> hook-above + horn/hat/breve
      • tilde/dot-below + GREEN ==> tilde/dot-below + horn/hat/breve
      • grave + AltGr ==> horn (or use AltGr-$ prefix) grave + acute ==> grave + horn acute + grave ==> acute + horn
      • GREEN-for-hat = grave = AltGr-z/AltGr-f/AltGr-m for à/è/ò. GREEN-for-ă/ơ/ư = å/ø/b = AltGr-r/AltGr-p/b
    • One must remember positions of quick-access AltGr-vowels with ` or ´, of additional "green keys" for ĂÂÊÔƠƯ, how to enter diacritics `, ´, ˜, ... via AltGr-prefix keys (`, ´, ˜ are where expected, dot below on AltGr-7 [possibly with AltGr on the vowel key], ˘ on AltGr-^, ˆ on AltGr-6; hook above on "English vowels" is on AltGr-´ with AltGr-vowel, and on "green keys" it is on AltGr-;). Also: đ/Đ is AltGr-& before d/D.
    • THE RULES:
    • All characters with at most one "accent" (except "horny" ƠƯ) can be entered "normally" (following the rules for AltGr-diacritics on "English letters", or via quick-access AltGr-vowels with ` or ´).
    • For characters with ` or ´ tone mark and another ornament (except "horn"), use the AltGr-prefix key for this "other ornament" with the quick-access AltGr-vowel for `/´-vowel.
    • To put tilde, dot below, or hook as the "second" diacritic, one should know additional positions on AltGr-layer: ĂÂÊÔƠƯ take places of ÅÀÈÒØÙ (which are on AltGr- WZF,LH; call these places "green AltGr-keys"). Preceed the green AltGr-key by the AltGr-prefix for the diacritic (given above). For example, ỡ is AltGr-~ AltGr-l.
    • This leaves `, ´ on horns ƠƯ and horns themselves. For the former, use AltGr-` and AltGr-´ on O and U with "the opposite ` or ´ accent". For ƠƯ, use AltGr-` on AltGr-O and AltGr-U (which are ÖÜ).
    • Desired heuristic for semantic: under the weight of additional accent, `-accent on letters collapses to a different accent: under ´ it collapses to a horn on O and U (Ơ and Ư) so one gets Ớ and Ứ (likewise for ´-accent under `). Over ¨-accent ` again collapses to horn (but ¨ evaporates, so one gets a pure horn).
