Changes for version 0.02

  • Minor additions to "principles" section of the docs. Document how Windows keyboard layout DLL work. PODify section on Latin-characters keyboard. Parse DerivedAge. Verbose mode of UName with script/block/age appended. Print out coverage. When multiple diacritics assigned to the same key, allow intelligent priorities by sorting by Unicode-age inside a group. When a sequence of diacritics is assigned to two keys in opposite directions, allow intelligent sharing. Allow chained (de)diacritics inside Diacritics() rule, as in 02dc+031b--0300: remove `, add horn, add ~. Allow a custom translation list, as in <subst-Vietnamese>. Recognize many new heuristics for pseudo-decompositions. Make the access to modifier letters take into account mapping of SPACE, and use Enter,Tab,C-Enter as well. Exchange roles of - and _. Repeated deadkeys. Separate visual bell for 32-bit chars in diacritic maps...
  • Eurkey++: [tentative webpage: k.ilyaz.org/v0 ] To enter ONE character from THE OTHER face, preceed by Shift-SPACE.
    • Latin face: identical to EurKey (but with enhanced diacritic prefixes, and full [monotonic] Greek).
    • Cyrillic face: *) identical to Russian phonetic (of X11) on the base layer; *) has all other letters of modern Slavic Cyrillic-based languages, XIX century russian, Kazakh letters on the AltGr-layer; *) has all the other characters of ISO 8859-5, Old Slavonic (except letters-titlo-form and powers-of-10), and those in flavors of ru on X11 (Tatar, Ossetian, Chuvash, Udmurt, Komi, Yakut, Kalmyk, Bashkirian, Mari) on AltGr-' prefix (the "bizarre variants key"). *) Has all titlo-forms (up to v6.1) accessible via AltGr-^ prefix key (for "bizarre ones" use a key with Shift, for the rest type the lowercase form [after AltGr-^]); double-AltGr-^ enters the titlo itself. Powers of 10 are on the AltGr-^ + digit. (ST as S, DJERV as D, vzmet as -.) Most keys are in the "expected" positions; but note the following:
  • '"/́´/ӹ/ӳ я/ѣ/ѧ/ѩ б/ѓ/ѹ/ѽ д/ђ/ӟ/ԁ й/ї/ҋ/ӑ ь/ъ/ӛ/ӕ ф/ѳ/ғ/Ӻ м/Ω±/ӎ/ꙟ ш//ԧ/ѐ щ//ꚇ/ѝ з/є/ѯ/ҙ ц/џ/ҵ/ќ
    • AltGr-' is the "get bizarre variants" key; so for д/ђ/ӟ/ԁ, ђ is on AltGr-д, ӟ is on AltGr-' д, and ԁ=U+0501 is on AltGr-' AltGr-д. Shift-AltGr-' gives ´. The keys ъЪёЁ are duplicated: they are placed above 3456 (as in the standard phonetic keyboard) AND they are placed as AltGr-variants of ь and е. The Latin punctuation keys "hidden" by ючшщэ (and over-digits ъЪёЁ) are accessible on AltGr-keys.
    • Extended prefix keys for Latin diacritics: Each can perform multiple functions; if several functions are applicable to a given key (the normal situation!) the best match is assigned to PREFIX + Key, the second best to PREFIX + AltGr-Key.
      • Pressing twice give the corresponding combining character; if followed by Space, Shift-Space, AltGr-Space, Shift-AltGr-Space, produces various related spacing modifier letters; if followed by | or AltGr-|, gives a vertical form etc (see below).
      • What is "the best match"? It is the position in the list below (left is prefered) combined with bizarreness of the symbol (less bizarre is prefered). Also, PREFIXed AltGr-Key may just add a second accent to what AltGr-Key generates (if this is "the best choice" as described above - it competes with "the second choice" for the base key); the [Vietnamese ACCENT] actions below operate only for adding SECOND accent on AltGr-keys, and only on "green ones": AltGr- WZFH,L (see below).
      • Alt-^ breve + caron + other breves + other carons + loop + belt + flourish Heuristic: Alt-Shift-6 inverts Alt-6 (which is, basically, hat-accent) Alt-; diaeresis + [Vietnamese hook above] + ogonek + cedilla + comma below Heuristic: ; is an offspring of double-dot and comma Alt-& macron + stroke + various other additions of straight line(s) On numbers 0,1,2,3,4: soft-hyphen, hyphen, en-dash, em-dash, horizontal bar On numbers 5-9: IPA tone modifiers ˥˦˧˨˩. Alt-7
  • ring above + [Vietnamese dot below] + dot above + dot below + various rings/dots + circle about
    • The other prefix keys work in pairs: the first one operates as described above, prefering accents on the left of the list; and the second one prefers accents on the right
    • Alt-' and Alt-`
    • acute + [Vietnamese acute] + hooks + tails + curls + horn + ticks + [Vietnamese grave] + grave Alt-~ and Alt-6 tilde + [Vietnamese tilde] + belt + descender + mutiliated + smallcaps + hat ("Mutiliated" means rotated/reflected/open/closed etc.)
      • Vietnamese input: 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 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).
        • 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).
      • Modifier letters: entered via the Latin AltGr-diacritic with a similar shape of "the principal diacritic". Following by space gives the standalone form of the diacritic; by Shift-Space the modifier form (if different; otherwise the other most similar modifier form). Two most visually similar "lower modifier" letters are entered by
        • and _; same for Vertical/Comma-like/Doubled/Dotlike - on \ and |; the Prime-like/Centered are on / and ?. As the last resort, follow by AltGr-Space, AltGr-Shift-Space, Enter, Tab, Ctrl-Enter, C-[, C-], C-\, Backspace and Control-Backspace to get other visually similar forms (in order). (The last resort method helps also when, for example, AltGr-& \ enters stroked-\ (which overrides the possible modifier semantic). All pre-v4.0 modifiers (and all non-letter 4.0-modifiers, and all IPA modifiers) can be entered. (See tables in .kbdd file.)
      • Combining diacritics: only the principal one is currently supported. Enter by double-AltGr-diacritic.
      • Accessibility features: prefix a key by AltGr-Shift-Space to access the AltGr-meaning of the key (useful if AltGr-key is stolen by the system). Works after linked-faces-prefixes too (but currently not before or after Latin diacritic-prefix). Example: AltGr-Shift-Space + | acts as AltGr-|. Repeat twice/3-times/4-times to access the AltGr-inverted linked face (and other flavors of the linked face).
        • Similarly, from Cyrillic personality, the linked faces are Latin, AltGr-inverted Latin, bizarre Cyrillic, and titlo-Cyrillic. So Shift-Space accesses Latin, AltGr-Space accesses AltGr-inverted Latin, double AltGr-Space accesses bizarre Cyrillic. And repetition of AltGr-Shift-Space access AltGr-inverted versions of Cyrillic, bizarre Cyrillic, titlo-Cyrillic, and Latin.
      • Linked faces for Latin: Cyrillic, bizarre-Cyrillic, and titlo-Cyrillic. The principal one is accessed by Shift-Space, the second by AltGr-Space, the third one by double-AltGr-Space. Alternatively, one access the second/third one by using Cyrillic prefix keys AltGr-' and AltGr-^ after Shift-Space prefix.
      • Shift-Space followed by various Modifiers-Space enters "visible representations" of space: ␢, ␣ and . on Space, Shift-Space, and AltGr-Space. Follow AltGr-Space by Space or Shift-Space to get wide non-breakable space (space-wide and digit-wide); follow Shift-AltGr-Space by Shift-Space to get narrow non-breakable space. The third linked face maps all spaces to narrow breakable space.
      • Vulgar fraction access: on bizarre-Cyrillic face, either enter a digit in denominator, or a digit in numerator with Shift-modifier. To increase numerator/denominator, add AltGr-modifier. (All fractions of v6.1 are accessible.) (From Latin: on AltGr-Space; from Cyrillic: on AltGr-'.)
      • Visual bell: non-existent prefix-key combinations generate the visual bell bell ♪. Combination which make sense but can't be entered on the give OS generate ♫ (currently 32-bit codepoints on Windows).
      • Add ќ on Russian-II-AltGr on c[ц] (this completes ISO 8819-5.) Add characters missing from ru X11 old slavic keyboard (except powers-of-10 and combining letters).
      • Add ―, soft hyphen, no-break hyphen and figure dash to Overbar map (on 4, ¦, ! and 0). Add ¤, kra ĸ and cedilla to CopyRight layer on $, q and comma. (This completes ISO 8859-N maps - except for Hebrew/Arabic/Thai letters.) (But not WGL4; or Adobe GL - about 760 missing [!!!] outside of combined characters, and "ARABIC|HALFWIDTH|FULLWIDTH|HEBREW|<control>|ARMENIAN|DEVANAGARI|BENGALI|GURMUKHI|GUJARATI|THAI|CJK.Symbols|CJK.Letters|CJK.Compatibility|Private.Use.Area|HIRAGANA|KATAKANA|BOPOMOFO|HANGUL|Small.Form" .)
      • Add ẗ to CopyRight layer as AltGr-t, and Ȩȩ cedilla as eE. How to do ḩ, ḥ, ɬ, ŀ, ẇ, ẉ, Ẏ, ẓ, Ǜ, ǚ, Ǘ (1.1 penalized by Vietnamese) and newer Ȧ, Ⱥ???
      • ḩ - romanization of Arabic ḥ - in dialects of Asturian ɬ - IPA ŀ - not recommended usage of l·l in Catalan ẇ ẉ - unknown Ẏ - Avestan, and ISO transliteration of Izhitsa Ѵ ẓ - transcription of Afro-Asiatic Ǜ, ǚ, Ǘ - unknown (transliteration of chinese?) Ȧ - Livonian, and ISO transliteration of Yus Ѫ Ⱥ - Saanich and precursor to Å in Norsk.
      • Fix shortcoming of the Greek section: dialytika-versions of ι and υ on ,., drahma ₯ and question mark ; on /?, micro sign on AltGr-M, and tonos, ypogegrammeni on `_. Add tonos-versions of vowels, symbol variants, and final sigma on AltGr-letters. (?!!! But not tonos-dialytika with Diacritics[+...]???? - it may work only on the given face, not elsewhere...)
      • Diacritic tables: all the non-char modifiers up to v4.0 are accessible, so are IPA letter-modifiers.
    • Vulgar fractions: 1/7 1/9 and 0/3 were missing. Scancodes for unusual keys were completely wrong (now taken from keyboard type 4 of kbd.h).
