Thanks. But before i try something weird, i want to explain. I need an 
accent to indicate where pronunciation stress is. Is happens on Cyrillic 
"а" letter:

Апроксимація (approximation)

So my goal is not to form a special letter, but to show a linguistic 
feature of the word.
Maybe we have better way to do this?

Vyatcheslav

1. you can do
    \def\myacute#1{\buildtextaccent\textacute{#1}}
    Апроксим{\myacute а}ція

2. of course you can also define an ugly shortcut:
    \catcode`'=\active
    \let\'=\myacute
    Апроксим\'ація

3. though in reality I would be most grateful if
    \'а
would work out of the box (at least it mkiv) and generate accent over
whatever letter comes next. If glyph doesn't exist, it could just
place one over a.

\placefigure setups

[Vyatcheslav Yatskovsky]

Hello,

Sorry for another newbie question, but how can I setup \placefigure so 
that its caption appeared as "Рис. 1.1"?
That is, with "Рис." prefix and numbered by subsection?

Best regards,

\setuplabeltext[ru][figure=Рис. ]

Thank you, Mojca. (1) works fine.

Before asking, I tried (3) option, but failed. Why it doesn't work? This 
is the classic way.

Not sure, but if that letter exists in unicode and not in your font
... that might be the most probably cause. If not, read further.

In mkii it has never worked since Hans reimplemented the mechanism (it
was different from Knuth's) to enable choosing the right glyph - if
font encoding has some glyph, it comes from the font, else it gets
composed from accent and letter.

Maybe I'm wrong, but from what I remember you only get those
characters that indeed exist in Unicode and the whole set of allowed
combinations is defined somewhere in source (see enco-def.mkii). I
don't know what exactly needs to be done in mkiv.

In mkii it will never get changed; I don't remember too many
complaints, but the truth is that (all) the characters that people
need are usually covered. If any were missing, they were added to the
list.

4.) I indeed forgot the fourth option: you can also build a slightly
larger file with all letter-accent combinations that you possibly
need.

I would assume that mkiv just builds all the accent combinations (to
support "\v c" constructs) from Unicode specification. If you need
some special character with a special accent like those definitions in
enco-def.mkii ... then you need to ask someone else for mkiv since I
stayed behind of a time for quite a giant leap.

(Hans, why cannot I put any accent on \schwa any more?)

Re: How to make an accent

[Arthur Reutenauer]

> Not sure, but if that letter exists in unicode and not in your font

  No, the letter doesn't exist at all in Unicode, and most likely won't be
encoded in the future either, due to the rule known as "normalization
stability".  Generally speaking, you have to input it as Cyrillic a followed by
combining acute accent, from the Unicode point of view.  Inside TeX, you should
of course build it with an accent macro.

Why formulas have space before but don't have space after

[Vyatcheslav Yatskovsky]

Hello everyone again,

There is a problem I encounter every time I use math and which drives me 
mad. Why formulas have space before but don't have space after? What is 
the most elegant way to dial with it?

In the following example, the expression is glued to the text that 
follows (which is certanly unwanted):

Допустимо нам поставлена задача з'єднати три точки на площині, що не 
лежать на одній прямій. Найпростішим рішенням такої задачі буде з'єднати 
послідовно дані точки відрізками прямих ліній, причому крива, при такому 
рішенні, буде апроксимуватися ламаною лінією. Рівняння прямих, що 
приходять через дві задані точки, як відомо, мають вигляд:

$$(х−х_1)/(х_2−х_1)=(у−у1)/у2−у1),$$

де (х1, у1), (х2, у2) -- декартові координати першої і другої точок, 
відповідно.


Best regards,
Vyatcheslav

Re: answers (cumulative reply :)

[Vyatcheslav Yatskovsky]

Thank you, friends, for answers.

To Hahns:
Can I make $$ envinroment behave like \startformula? In other words, to 
redefine $$ to be substituted by \start-stop formula? Writing 
\startformula and \stopformula every time is too verbose.

To Mojca:
OK, the current solution works for me. Don't want to complicate it 
further, just want to point out that Knuth compatibility is broken :)

To Wolfgang:
\setuplabeltext[ua][figure=Рис. ] works fine indeed. But how to make it 
numbered by subsection?

Thanks again
Vyatcheslav

I don't think so. You probably didn't get any output at all for that
character, right?

Knuth's 7-bit TeX doesn't support Cyrillic at all, so you probably get
no output either which makes it 100% compatible with what you get.

well, time spent on markup is often way less that getting the content so

Drawing interpolation curve in MP

[Vyatcheslav Yatskovsky]

Hello,

I have a crazy idea: can I draw 2nd order curve in metapost, provided 
that I know coordinates of 3 points: begin, center, end? And place 
markers onto those points.

No, metapost does third-order curves.
