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).

Re: [NTG-context] update
Hi Hans,
Thank you very much for the new update.
Everything seem to work like a charm. In particular I played with the
\underbrace and \overbrace when adding something under the \underbrace, or
above the \overbrace, like in
\startformula
\overbrace{1+x^2+a}^{= -1} +
\underbrace{ax^2 + bx + c}_{=2} = 1
\stopformula
and it works great !
Best regards : Otared

[NTG-context] barring changes
Please consider the attached example – some of the “barring” macros are
defunct already for a while, some more within a TABLE:
\underbar works, but not in TABLE
\underbarsworks
\underdot doesn’t work
\underdotsdoesn’t work
\underdashdoesn’t work
\underdashes doesn’t work
\underrandom doesn’t work
\underrandoms doesn’t work
\overbar works, but not in TABLE
\overbars works
\overstrike works, but not in TABLE
\overstrikes works
\understrike works, but not in TABLE
\understrikes works
The nested example
\overbar{Über} \underbar{Unterstrich \underbar{steigt \overbar{auf} den
\underdot{Unterberg}}}.
works only once, afterwards all the underbars are missing.

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

Re: [NTG-context] Suggestions for more math classes?
On 1/27/2022 9:36 AM, Mikael Sundqvist via ntg-context wrote:
Dear all,
While discussing spacing in math with Hans, we have come to the
conclusion that to have better control and cleaner code there might be
a good idea to have more math classes than the usual ones in TeX (ord,
op, bin, rel, open, close, punct, inner (and some that we need not to
think about)).
So far, Hans has implemented frac and rad for fractions and radicals.
The fractions has been a funny construction, being put inside empty
delimiters, and so surrounded by the \nulldelimiterspace (which has
been set to 1.2pt, independent of font size). Now we have better
control of the spacing around fractions.
Hans has opened up (even in the code) for the addition of more
classes. The overall aim is to have a more coherent and logical way of
typing math, without manual adding of (arbitrary) spaces every now and
then. For example, we have always written \int f(x)\, dx to have a
thin space between the closing parenthesis and the d in integrals.
There will (most likely) be a differential class. Since the d might
occur in other places in a formula with integrals, one cannot just
simply give the letter d the differential class, and we are currently
discussing the correct way for the user to type it. If you have
suggestions, please let us hear!
Some further suggestions by Hans are (see below for two more)
13 imaginary
14 differential
15 exponential
16 function
Q1: Do you have any further suggestions on new classes (or comments on
these)? It might be good to think about situations where you have felt
that you need to insert manual spaces such as \, or \! to obtain a
better result.
I give one contribution: I asked a colleague to look in his TeX files
for manual spaces, and he came up with several \, (usually before the
d in integrals) but also with \!. This \! occurred mostly in fencing
situations to have the exponent come a bit closer to the closing
parenthesis.
\left( \frac{x}{2} \right)^{\! k+2n}
I have seen this in many places before, so no originality is claimed.
Two more classes that we thought of are under and over. Say that we
have a\overbar{bc}d. Should the spacing between a and the \overbar{bc}
and the spacing between \overbar{bc} and d always be tight? If so,
these might just be ord, and no new class needed (although one could
argue for adding the classes now, set them up as ord, and thus being
able to configure them according to taste/need).
Q2: Do you have any real examples of constructions with \overbar,
\underbar, \overbrace, ... or if you have any strong opinion, please
raise your voice!
Here is a teaser:
\starttext
% in context we put digits in their own class, the next is the default:
\letmathspacing \mathdigitcode \mathordinarycode \mathordinarycode
\mathordinarycode \mathordinarycode
% but we can adapt the inter digit spacing (\mathdigitcode == 20 in
context, \mathordinarycode is one fo the traditional class codes):
\setmathspacing \mathdigitcode \mathdigitcode \allmathstyles = 2mu
% and also change it when needed
\startTEXpage[offset=10pt]
$ x = 1234 = z $\par
\begingroup
\setmathspacing \mathdigitcode \mathdigitcode \allmathstyles = 4mu
$ x = 1234 = z $\par
\endgroup
$ x = 1234 = z $\par
\stopTEXpage
\stoptext
The result is attached. So maybe Mikaels explanation above and this
example will trigger demand.
One of the possibilities is that users define their own classes and put
characters in it. (this can be domain specific and domains is something
that has been on the todo for quite a while.)
For that reason we might bump the current number of classes (we have 32
classes compared to the 8 that regular tex has) to 64 (which is possible
when we bring down the number of families to 64 (currently 128 compared
to 256 in luatex and 16 in regular tex) which is still plenty and way
more than we ever need (so if needed we can borrow bits for the math
unicode range which is now limited to 0xF; it was already limited
anyway).
This move also makes it possible to remove some other hacks (with the
usual 'a pity to throw nice code away syndrome' side effect) and can
have some 'initialization of old school ascii' side effects (neglectable
because we can set it up via the emacro package).
For the record: the \Umathspacing primitives have been
dropped but can be emulated easily (in the end it saves hundreds of
primitives).

Nested bars have a parameter ‘dy’ which controls the vertical shifts
needed to make sure that they do not overlap. Text backgrounds do not
have that option at all.
i've added that so one can nest the mp driven ones but still within the
same category ... i'll look into a mix (more complex management wise so
typically a rainy weekend thing; i know how to do it but ...)
If I use \overbar within \underbar, the same dy is used, i.e. in the

[NTG-context] mathring circle above a letter
Hi all,
The \mathring command puts a small circle above a letter, but in some fonts
(namely Lucida OT) that circle is too small. So thanks to a hint by Hans and
Wolfgang some years ago I use the following definition which works fine when
used alone. But in maths, one needs sometimes to use it with the command
\overline (or \overbar) and the result is not nice.
Can someone tell me please whether it is possible to modify the \mathring
command so that th ecircle is a little bit larger, or the one I define below as
\interior in order to have a correct result (more clearly said: I would like
the small circle to be put above the bar which is itself above the A in
$\interior{\overline{A}}$).
Thanks for any help: OK

Re: [NTG-context] Fwd: Macro to write a vector (Metafun) is broken
Hi Hans,
No, I did not check this file but only update context Standalone. I guess
this is not enough since the compilation does not work.
Thank you

Not a solution, but in math mode you should use $\bar{1}$ which is the proper
math accent.

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

Dear Henri, Thank you for your reply. I used to use ‘\overline’ in LaTeX as shown in many texts, but it is time to change. Thanks again.

Re: [NTG-context] \overline and \overbar
Neither is correct in a mathematics context. Use \bar.

[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.

[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.

[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,
Xan

[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!

Re: [NTG-context] underbraces slightly too narrow (with MkIV 2013.05.28)

In certain cases, display-mathunderbraces are not quite wide enough.
Here's a minimal example:
===

\placeformula\startformula

===
Using 2013.05.28 00:36 MKIV (from vanilla TL2013), the left brace tip
starts under the vertical bar of the 1, instead of enclosing the serif
as well. The right brace tip ends between the last two tines of the
m, instead of enclosing the whole m and its serifs.
With 2013.04.09 10:38 MKII, the brace tips extend just slightly beyond
the 15 cm, which is better. However, they seem slightly too close.
As a test, I ran the comparable plain-TeX file through LuaTeX and PDFTeX.
==
$$
\underbrace{15\,\rm cm}_{L}
$$
\bye
==
The gap between the right brace tip and the text is slightly greater
(with either LuaTeX or PDFTeX), and it looks right.
(With the 2012.05.30 MKIV on live.contextgarden.net, the result is
similar to the Lua/PDFTeX versions, though not identical, and also looks
reasonable.)
it has to do with the fact that we have opentype math fonts now and
these are not compatible
what you observe is the fact that we have a discrete number of sizes
till we run out of them and go stretchable
anyhow, i've now defined then in a different way (ok, some more trickery
had to be applied as it's one of these aspects of open type math that
still inherits old stuff) so in a next version you can do this:
\setupmathstackers[vfenced][hoffset=10pt]
is it looks like these commands have built-in \limits, these are now set
for
\overbrace
\overparent
\overbracket
\overbar
\underbrace
\underparent
\underbracket
\underbar
\doublebrace
\doubleparent
\doublebracket
\doublebar

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.

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

Maybe there could be parameter like

[NTG-context] How to achieve a LaTeX-center-like thing
Hi,
I'd like to have something like this:
Let $X$ be a~real Banach space, $D$~an open subset of~$X$
containing~$0$ and $T$ a~continuous mapping from $\overbar{D}$
to~$X$. We say that $T$ satisfies the {\em Mönch condition} if the
following implication holds:
\blank[small]
\startalignment[middle]
If $C\subset\overbar{D}$ is countable and
$C\subset\clconv\bigl(\{0\}\cup F(C)\bigr)$, then
$\overbar{C}$ is compact.
\stopalignment
\blank[small]
Is there any option for alignment which would enable me not to put the
blanks manually?
TIA,

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

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

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?

wanted to add a simple TeX label (\tt \overbar{E}) to the drawing
macro, but failed.
When including the line marked with % 1 the TeX run fails. I don't
understand why.
The line with % 2 is taken frome the metaobj manual (section 5.8) [1],
but including this doesn't work either.
It would be great if someone could tell me what's wrong with the mp-code
below and explain how to place a (TeX) label inside a metaobj object.
Thanks in advance,
Stefan.

[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

Of course, using entity names instead of unicode values is better for readibility and maintanability, but IMHO it is not a solution to the question.

I guess that in MathML stretchiness is more systematic and should apply to most characters, provided that they can stretch (http://www.w3.org/TR/REC-MathML/chap3_2.html). In this doc it is said: By default, most horizontal arrows and some accents stretch horizontally. now an implementation needs to adapt to math or text (or just gamble since it may be that i want a non stretchable macron over x+y+z); my guess is that as a result, many implementations are more complex than needed From my little window (since I don't know how it works internally) I would say that in mathml stretchiness is required in things like mover or munder, if the character allows it, and depending on stretch attribute. But it's sure that it does not make things easier. (btw, in pure text, it's still not clear if the macro glyph sould be chosen or a stretchable hrule) What is not clear to me is if unicode explicitely allows a combination of a non spacing mark (accent) and a *group* of characters. In the specification I've only seen that it can apply to a base character. If it can apply only to one character, a glyph seems enough. (i think that one problem of unicode/xml/mathml is that it is used in typesetting systems but not in all aspects is designed (or used) to facilitate high end results; therefore a 24/32 bit tex still needs to provide much detailed control) Yep!

but then we miss the utf 8 encoded ones, so we then need to hook it into

To generalize: all my attempts to enter mathmode when the bodyfont is
Greek (using one of the fonts in Thomas Schmitz’ Greek module) fail
because of insufficient symbol fonts.
I wonder if this bears of the fact that in this module the fonts have
to be defined at every size used in the document. The relevant line
in type-tasgreek is
\definebodyfont
[30pt,25pt,20pt,18pt,17.3pt,14.4pt,14pt,12pt,11pt,10.5pt,10.1pt,10pt,
9pt,8pt,7pt,6pt,5pt,4pt]
[rm]
My environment file sets the body font size to 10.1 pt.
I'm not the font expert, but the problem seems to be that
math small text isn't being set (if I see it correctly,
you're using math mode to enter a superscript). I would
suggest you try \text instead of \hbox in the math part, and
even better try \hi{superscript text} or \super{superscript
text} for the superscript.

Alan,
I know next to nothing about math, but I know that the Greek
typescripts do not define a math font. So you will get errors doing
math when the body font is Greek. I wish I could help, but defining a
math font is beyond my abilities. If anyone is interested in doing
it, however, I will be happy to provide the specs for the Greek fonts.
