Hi all,

I'd like to contribute a new package greek-polytonic.el to ELPA, or where
ever it is more appropriate.

The latest version is maintained at
https://github.com/jhanschoo/quail-greek-polytonic/tree/fsf .

Rationale: Polytonic Greek input is of interest primarily to classicists,
people who want to reproduce Ancient Greek quotations, and for input of
Katharevousa Greek. There already exist several input methods for Polytonic
Greek in the greek.el file distributed with Emacs, but this file improves
over them in the following 2 ways:

1) Mapping based on "standard" Win and Mac layouts—The existing input
methods' mappings are modeled after ad-hoc polytonic input schemes devised
by classicists very early in computing history, in conjunction with
specialized software. The mappings I use are modeled after Mac and Windows
polytonic Greek keyboard mappings, (in turn modeled after monotonic Greek),
and hence require less context-switching to use for people accustomed to
modern and popular Greek keyboards.

2) Input of combining character sequences possible—While the existing input
methods allow for the input of bare letters and precomposed
letter+diacritics, but not for Unicode letter+diacritic sequences that are
not represented by precomposed characters. For example, the sequence
<alpha>+<combining macron>+<combining acute accent> is not represented by
any precomposed character, but appears frequently in critical editions of
classics. greek-polytonic.el allows for the input of combining characters
themselves, and substitutes such sequences with their Unicode-canonical
precomposed equivalents if they exist; hence input from this method
satisfies Unicode-NFC (Normalization Form Canonical Composition), while
allowing input of sequences that have no corresponding precomposed
character. Though it is to be admitted that font support and Emacs's
display support for such decomposed sequences is still rudimentary and the
sequence may visually appear funky.

While I consider this package functionally complete, there are several
avenues for further work if there is interest:
—Allow "prefix" input of diacritics à la most other input methods.
(currently only "postfix" diacritic input is supported)

—Allow input of greek numeral modifiers, of archaic letters, and of greek
"symbols".
—Allow input of non-combining versions of diacritics.

Thanks for your attention.

Bests,
Johannes Choo

;;; Commentary:


;; This package provides a method for inputting polytonic Greek, based
;; on the Mac and (to a lesser extent) Windows polytonic Greek
;; keyboards, with several additional bindings to aid classical
;; scholars (TODO).
;; cf. http://unicode.org/charts/PDF/U0370.pdf Greek and Coptic
;; and http://unicode.org/charts/PDF/U1F00.pdf Greek Extended
;;
;; Where Unicode specifies a NFC for characters in the above tables,
;; we use the normalized forms instead.
;;
;; Where a decomposed sequence of letters and combining diacritics is
;; necessary, we use the following sequence, modeling the canonical
;; Unicode decomposition of procomposed characters where available,
;; and from closest to furthest where unavailable:
;;
;; <letter>-<length>-<diaeresis>-<breathing>-<accent>-<ypogegrammeni>
;;
;;
;; For convenience, we list here all the combining diacritics that
;; this input method inputs, or that a precomposed character that this
;; input method inputs decomposes into.
;;
;; <length>:
;; U+0304 COMBINING MACRON
;; U+0306 COMBINING BREVE
;;
;; <diaeresis>:
;; U+0308 COMBINING DIAERESIS
;;
;; <breathing>:
;; U+0313 COMBINING COMMA ABOVE
;; U+0314 COMBINING REVERSED COMMA ABOVE
;; U+0308 COMBINING DIAERESIS
;;
;; <accent>:
;; U+0301 COMBINING ACUTE ACCENT
;; U+0300 COMBINING GRAVE ACCENT
;; U+0342 COMBINING GREEK PERISPOMENI
;;
;; <ypogegrammeni>:
;; U+0345 COMBINING GREEK YPOGEGRAMMENI
;;
;; Relevant known naming defects in Unicode names in the two blocks:
;; U+039B is GREEK CAPITAL LETTER LAMDA
;; where GREEK CAPITAL LETTER LAMBDA might be expected.
;; U+03BB is GREEK SMALL LETTER LAMDA
;; where GREEK SMALL LETTER LAMBDA might be expected.

Is this a good idea?  It seems to go against the intent of whoever is
typing the text: they do want the decomposed characters to appear in
the text.  Emacs will automatically (by default) compose them on
display (and if it doesn't, that's a bug that should be reported and
fixed), per Unicode requirements, and if the font supports the
precomposed glyph, you will actually see that glyph on display.
Replacing characters with their NFC equivalents should IMO be a
separate feature, not something an input method does.  Am I missing
something?

Thanks.

I'm not sure what you mean by "want the decomposed characters to appear
in the text," but when I am writing polytonic Greek and type the
sequence above, all I want is to see an alpha+macron+acute in front of
me. I don't particularly care how it is represented internally. As long
as the input method produces a valid representation for what I want, it
should be fine.

By the way, thanks for trying to solve this problem -- it's been a
long-standing one. I solved some of that for myself via XCompose, but
that's not portable.

Font and application support may be the biggest hurdle, though. It is
for me. What are the consumers of the texts you are producing in Emacs,
TeX and friends?  I'd be interested in a properly working TeX setup for
polytonic Greek, but that's another thread (in another group, maybe?).

Cheers,

On display or in the buffer?  If on display, then Emacs should already
do that, provided that the font you are using supports the composed
characters.  That's because by default we have the
auto-composition-mode turned on.

I was talking about what's in the buffer.  I think that if the user
types a sequence of characters, Emacs should generally put those
characters unaltered in the buffer.  If the user wants a precomposed
character, she could always type that character's codepoint using
"C-x 8 RET", no?

But maybe I don't know enough about the expectations of users who
would use greek-polytonic input method, maybe in some use cases such
automatic composition in the buffer is expected?

This is good for several reasons:

* It makes C-b and C-f do the natural thing.

* It makes search do the natural thing.

Maybe we're talking about different things...

Input methods do automatic composition all the time. That's what 
they are expected to do. I do it every day when writing Portuguese 
text. Consider "á": I just wrote it by switching input methods and 
typing "<acute>-<a>". What ends up in the buffer and on the 
display is one single character. If my buffer had instead 
"<a>+<combining acute>" I would consider that a bug. Unicode 
supports the combination, I want the combination there.

This means that the input method's semantics is to translate a 
sequence of keys into the most natural underlying 
representation. For "a acute," it is "á", not "a+combining acute", 
and nobody blinks an eye.

For polytonic Greek, however, the problem is that Unicode does not 
have pre-composed characters to represent all the 
possibilities. Combining characters will be needed, but the input 
method can -- and I argue /should/ -- combine what they 
can. Example:

* Typing "a + macron" should give U+1FB1, "Greek small letter 
  alpha with 
  macron," /one/ character, just as "á" above. Similarly, I would 
  consider "<a>+<combining macron>" a bug.
* Typing "a + macron + acute" should give the above plus a U+0301 
  "combining 
  acute", because it is the best it can do -- and it is what fonts 
  like Skolar expect.

"C-x 8 RET" is not a solution if you are typing in a language that 
requires it once or more every word. (Again, that becomes the job 
of the input method.)

By the way, I'm all for greek.el supporting polytonic Greek 
natively and naturally. I don't remember what the problems were, 
but I gave up on it quickly when trying polytonic because it 
didn't work.

Cheers,

True, and I was not talking about that.

More accurately, input methods normally read ASCII characters and
produce non-ASCII characters, whether accented or not.  By contrast,
your original text:

led me to believe that your input method takes three non-ASCII
characters, alpha combining macron and combining acute accent, and
produce from them a single composed character which is their NFC
precomposed character.  This is not what an input method should do,
IMO.

However, I see now that no such NFC composition is being done for
non-ASCII input (right?), so I guess I misunderstood; sorry about
that.

Emacs combines these automatically, but only on display; in the buffer
we still have several separate codepoints.  And I think this is
correct.

I was talking about adding your input method to greek.el.

No need to be sorry about anything -- wonders of written 
communication. I think we're on the same page now.

Not /my/ input method, I'm just encouraging the OP to think about 
making this an improvement to greek.el instead of a separate 
package, as you suggested in your first e-mail :)

Sorry for a late reply. I found a couple typos and it actually needs to be
updated.

@Cesar:

I actually have a working polytonic Greek setup for LaTeX; (more
accurately, XeLaTeX and LuaLaTeX); send me a message and I'll send you a
minimum working preamble :)

@Eli:

yes, I think putting it in greek.el would be a better option, but I don't
have contributor rights, and so far this has been the easier way for me to
distribute it. I'd be happy to if someone can help me with that.

In an ideal world... yeah. De facto, polytonic Greek online and presumably
in most digital systems use the precomposed forms, and /all/ polytonic
fonts I'm aware of do not gracefully handle the placement of decorations on
greek letters.[1] Some fonts don't display the accents, some fonts have
them overlap, and probably all fonts don't place the combining breathings
(single-quotation-commas) in the right place. When writing this I found
that my favorite programming font on emacs actually crashes my Linux system
when using these combining characters![2]

This is the most prevalent compromise I've found online. greek-polytonic.el
gives the most graceful fallback, compositing into precomposed forms
whenever available.

[1]: I think this is in fact the case, de facto, for most
Latin/Greek/Cyrillic documents. For example, I've observed that in movement
in emacs, decomposed characters count as two characters, but all the
documents so far I've opened have their accented characters count as one.
Korean... is similar in its poor de facto support for decomposed
characters. The only natural language that I know writes in decomposed
characters de facto are the Indic languages!

[2]: This is a bug on emacs or the window system, but I don't even know
where to begin diagnosing it.

Bests,
Johannes
