What do you run directlua in LMTX?
in this case, what does does lualibs-os provide? os.resultof is built
into context so that should just work
ok, i did as search on ctan and it looks like that lua file is just the
context l-os one renamed so no need to load anything, in fact, loading
it might even break the built in when it does overloads

One can also try to instead use the accent mechanism instead of a stacker:
% engine=luatex
\definemathtopaccent[widebar] ["0305]
\startTEXpage[offset=3pt]
$\overbar{OA}$
$\widebar{OA}$
\stopTEXpage
The \widebar is defined (almost) like that in lmtx.

Not really. It's a a bug in the fonts (that will stay if only for
compaibility reasons). There is a catch in mkiv that compensates for it
but only when characters are not there. So, for these two I now force
the catch.
In lmtx we have a bit different approach: we just assuem they are wrong
in all fonts and fix them or replace them. We also have a more advanced
math engine so we can control placement better.
There are also 'font parameters' involved that can be bad (i guess that
designers can't really test math font parameters). In lmtx we have more
of them, beyond what opentype math provides.
All of this is handled in goodie files. That mechanism is present in
mkiv but no one ever bothered to spent time on it. That said: the last
two years Mikeal and I spent a *lot* of time on math and we don't really
look back at mkiv / mkii also because there is way more neat things now
(most probably go unnoticed) ... you can read about it in some documents
that come with context, articles in tugboat, and there are talks by
Mikael at tug meetings on YT.
The output with Luametatex is correct but Luatex creates a raised bar
(and different linebreaking).
\showglyphs
\startTEXpage[offset=1ex]
\ruledhbox{$\overline{OA} = \overbar {OA} = 4.2$}
\par
\ruledhbox{$\underline {OA} = \underbar {OA} = 4.2$}
\par
\ruledhbox{$\widetilde {OA} = \widebar {OA} = 4.2$}
\par
\ruledhbox{$\overbracket {OA} = \underbracket {OA} = 4.2$}
\stopTEXpage
I'll add a 'force fix in spite of extensible being present' in mkiv. In
lmtx we always fix also because we drop in nicer shapes (watch the round
tips in lm and fancy tips in antykwa) and concluded that fonts will
remain as they are.
Hans
As you suggested, I will give a try to LMTX but be aware most user still use
MKIV until most distros upgrade the texlive version of context to LMTX.
It's not that hard to install lmtx alongside. If distributions take from
texlive then likely you also end up with files that are not needed (base
package) and lack some fonts (esp math) by default. You'd also benefit
from the last couple of years advancements. Keep in mind that for a long
term tex (document) project a snapshot approach is healthy because you
never know what a distribution adds / replaces (esp fonts can be a mess
and you want to know what you use).

I don't understand why you are using $\overbar$ in math mode. Do you want
$\bar{\alpha}$ and $\bar{\beta}$?

[NTG-context] Overbar bug
Hey there,
please have a look at the following example:
\starttext
$\overbar{\alpha} \overbar{\beta}$
\stoptext
The first one works just fine, whereas the second one looks very odd.
(At least in MkIV...)
Any ideas?
Best,
Johann

[NTG-context] overbar in math mode is asymmetric over "F"
Hello,
the following small sample illustrates the problem:
\starttext
\enabletrackers[math.stackers.texts]
\math{\overbar {ABC}} %<-- somewhat okay
\math{\overbar {F}} %<-- too short on the right side
%manual fixing
\math{\overbar {ABC\mkern\onemuskip}}
\math{\overbar {F\mkern3\onemuskip}}
\stoptext
I wish to have an overbar that extends over the exact boundingbox of the
letter or sequence of letters. How can this be done in context without
manual fixing?
Thnk you,
Bernd Donner

Re: [NTG-context] \overline and \overbar
Dear,
I am sorry to bring up \overline, \overbar, and \bar issue.
Here is a sample file and
I attached two pdf files which were compiled using two different version of
ConTeXt.
Under the LuaTeX v. 1.03, ConTeXt ver: 2017.03.02 22:23 MKIV beta, the output
overlineB.pdf is OK,
but under the LuaTeX v. 1.04, ConTeXt ver: 2017.05.14 19:09 MKIV beta, the
output overlineA.pdf is strange.
Would you please check what is the problem?
Thank you.
Best regards,
Dalyoung

[NTG-context] \overline and \overbar
Dear all,
In the following sample, the outputs of \overline and of \overbar are slightly
different.
I used \overline in LaTeX.
But it takes more vertical space that cause the alignment trouble while using
\overbar has no problem at all.
Is it normal behavior?
Thank you.

Re: [NTG-context] underbar and overbar
Bump. Even a simple yes/no answer would be nice. Is this behaviour intended?

[NTG-context] underbar and overbar
Ahoi,
I played with the "bar" commands:
\underbar{underlined \underbar{more and \underbar{more} \overbar{\underbar{and}
\overbar{over}} and back}}
While stacking bars is nice, overbar and underbar exclude each other, while
underbar takes precedence. Is this intended? I expected different results.
Greetlings, Hraban

[NTG-context] Prime and overbar
Hi,
$\overbar{OA'} = 3,4$, puts me overbar with two steps: one for $O$ and one for
$A'$. Is there any way for putting overbar just on top of the expression?
Thanks,

[NTG-context] Adjusting overbar for a special font
Hello there,
I tried to overbar an arabic word, and noticed, that the bar is too low
and overlaps the letters. While producing a minexample, I noticed that
this might be a issue of my font, because this does not happen with
Arial. See this minexample:
\definefont[arial][name:arial*arabic at 12pt]
\definefont[arabicuth][file:UthmanicHafs1Ver09.ttf*arabic at 12pt]
\starttext
\startalign[r2l]
\arial
كَلَّا لَا تُطِعْهُ \overbar{وَٱسْجُدْ} وَٱقْتَرِب ۩
\arabicuth
كَلَّا لَا تُطِعْهُ \overbar{وَٱسْجُدْ} وَٱقْتَرِب ۩
\stopalign
\stoptext
and compare the compiled pdf in attachment.
You can download the used font-file UthmanicHafs1Ver09.ttf here:
http://fonts.qurancomplex.gov.sa/download/UthmanicHafs1Ver09Font.zip
We have discussed this font here month ago, hans commented: yes, but
calling this a normal font is somewhat over-the-top
So it is quite special - but still best available font (free or
commercial) for typesetting the holy quran.
But setting the bar a bit higher should be easily possible, independent
of these font-lacks, right? The solution should be independent from the
chosen font-size.
Thanks!

This is ok: all the elements have MathML namespace
Now, in the next example you declare the mml name space
and the you use it only for
mml:mathand /mml:math
--- all the other nodes that are not in the mml namespace are skipped.
But with
msubsup xmlns=http://www.w3.org/1998/Math/MathML;
you still declare the MathML namespace, so they are ok
and then with
mrow
mover accent=true
mrow
msub
miU/mi
miA/mi
/msub
/mrow
moOverBar;/mo
/mover
/mrow
you are again *outside* the MathML namespace so they are your private markup
and context doesn't render as MathML --- after all they are your private
markup.

1. Specify which command you want to change, e.g. “\overbar”.
2. The offset” key controls the distance between the text and the first rule
while “dy” controls the distance between multiple rules.

offset and dy don't seem to do anything. Also, I don't know the
difference between the two params... Please advise.
1. Specify which command you want to change, e.g. “\overbar”.
2. The offset” key controls the distance between the text and the first
rule while “dy” controls the distance between multiple rules.

Re: [NTG-context] math: `\overbar` with fractions and subscripts
Dear Otared,

In text $\overline{q} = \frac{\overline{q}}{\overline{α_0}}$.

thank you for your answer. `\overline` works as you say, but it looks
typographically different in the respect that the bar is closer to the
letter, which of course solves the issue for the inline fraction. For α
this looks quite strange in my eyes. But I do not know a lot about
typography.
Please find the PDF-output attached with the following ConTeXt version.

IIRC, \overline is meant for long entities, like \overline{(a+b)}. For
single letters, it is better to use the accent \bar.

[NTG-context] math: `\overbar` with fractions and subscripts
Dear ConTeXt folks,
I do have some problem with the following example (also attached,
executed with `context test`).
\starttext
\startformula
\overbar{q} = \frac{\overbar{q}}{\overbar{α_0}}
\stopformula
In text $\overbar{q} = \frac{\overbar{q}}{\overbar{α_0}}$.
\startformula
\overbar{q_0} = \frac{\overbar{q}}{\overbar α}
\stopformula
\stoptext
I am using the latest ConTeXt Minimals distribution.

1. The bar divides for subscripts/indices.
2. If you look at the first fraction, the bar is as long as the stroke
from the fraction and therefore I think too long.
3. When inlining the fraction in text the bar fuses with the stroke from
the fraction.
Are these know problems or do I just use the wrong commands?
Thanks,
Paul

[NTG-context] underbar/overbar to long with one character in mkiv
Hi,
there was an earlier issue with \underbar{b}
http://archive.contextgarden.net/message/20091109.094902.baf77ffc.en.html
which seems somewhat related to my problem. When providing only one
character as argument to \underbar or \overbar and a following space (or
paragraph ending) the line is also under/over that space. Is this
intended? Example:
\starttext
\underbar{b} \overbar{b} \underbar{b}
$\underbar{b} = \overbar{b} = \underbar{b}$
\stoptext
A fix for this would be to use \underbars{b} or \overbars{b} instead, btw.
Best wishes,
Stefan
