Hi list,
I noticed that the sign for the square root does not adapt to the size

In what sense? Sqrt's grow in discrete steps.
Oh, I didn't know that. For my feelings, all variables should have the
same size here (a,b and c).
Hopefully ok now ... I also made the mathstyle more conformant the new
math style mechanism and added coloring of the fraction rule.

Thanks guys for trying to solve which I definitely tag as a bug ;-). It seems
there is no faster solution but surely Hans will find one ;-) By the user
perspective it's an annoying behaviour and I have to change manually the

end. It's too much technical discussion for me. I'm sorry I can't do anything
else. But I'm glad to see this discussion (so mantain me as CC)
If I could do anything, please say to me.
Can you test your example with the mixedcolumns environment
instead of the normal columns environment (use the latest beta).
Wolfgang
Yes, it works perfectly (I attach my example).
Can someone put reference on wiki on such environment? Useful for novice
users like me.
Thanks for all,

[NTG-context] vertical position in itemize and math
Hi,
I have two problems with vertical position, one in itemize and one in
math. The example below show them both.
\starttext
\startitemize[n]
\item
\startitemize[a][left={},right={)},stopper=]
\item Bla bla
$\theta = \arctan\bigl(\frac{\bar{y}^2}{\bar{x}^2}\bigr)$ % comment
this line out to see the problem disappear
\stopitemize
\stopitemize
Let
\startformula
A=I-2\frac{NN^T}{N^TN}\,N=\frac{1}{9}X.
\stopformula
\stoptext
The first one is the vertical position of the a) and the following
formula. This is pushed down (because of the formula it seems). What
if I want the a) aligned with the 1.? (I wrote about this problem some
time ago, and it got solved, but that time no math was included)
The second one is the division line in \frac{NN^T}{N^TN} that look
pushed down to me. I'm not sure how it should be, but my guess is
aligned with the minus sign or so.
All this with the latest ConTeXt suite.

expected. In particular, the first equation moves from page 1 to page 2,
and the 12 x moves from page 2 to page 3.

You need to ensure that the width of the columns does not change from each
step. There is no easy way to do this with \startmathalign, but you can
try \startTABLE, with explicit values of widths. (Some day, I will check
how beamer does this with aligned equations).

Re: [NTG-context] Math typesetting problems
Indeed it seems like the alignment is good with \dfrac, but this does
not solve my problem, since I wish to also use fractions with
script-size or scriptscript-size (\xfrac, \xxfrac). The specific
formula I have is
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +
U(t-s)) + \frac{(S(u-t) +

I'll look into fractions later this week. All the fraction macros of
ConTeXt were based on \genfrac macro from AMSTeX so, in principle, they
should behave in the same manner.

were based on \genfrac macro from AMSTeX so, in principle, they should behave

The \frac command uses \vcenter for the content while \dfrac and \tfrac only
set the mathstyle before placing the content with the \over primitive.

Hi Janne,
Personnally I prefer to use the Plain TeX alternative \over (which works fine
in ConTeXt), that is
${a \over b}$
instead of
$\frac{a}{b}$
Compare the following two outputs in the example you want to typeset: I think
the second is more or less what you want
\starttext
Using \type{\frac} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +
U(t-s)) + \frac{(S(u-t) +
U(t-s))^2}{(u-s)}}{2(t-s)(u-t)}}}{\sqrt{2\pi\frac{(t-s)(u-t)}{u-s}}}
\stopformula
\blank
Using \type{\over} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = {
e^{-{(u-s)x^2 - 2x(S(u-t) + U(t-s)) +
{(S(u-t) + U(t-s))^2 \over (u-s)} \over 2(t-s)(u-t)}} \over
\sqrt{2\pi {(t-s)(u-t) \over u-s}}}

[NTG-context] Math typesetting problems
Hi all,
I've run into a couple of problems with math typesetting. (I'm using the
latest ConTeXt standalone beta.) The following doesn't print [x,x] at all:
\startformula
[x,x]_t = x
\stopformula
It can be fixed by using \left[x,x\right]_t, but I find the behaviour weird.
Another problem I have is related to the positioning of minus signs in
front of fractions. I would expect the minus sign to align with the
horizontal line of the fraction, as it does on LaTeX. Below is an example
formula to illustrate my point. The result seems to be independent of the
font in use.
\startformula
-\frac{e^{\frac{4}{5}}}{4}

With \dfrac it looks good.
With \fraction the minus sign is on the top of the fraction.

\frac{dy}{dx}\Big|_z
The \Big is to scale | according to the size of the \frac.
I am using newmat and amsl modules that have supported
the native math mode commands till now. But context does
not recognise \Big.
What is the native context way of doing this?
Regards,
Devendra
MWE (in case its needed)---
\usemodule[newmat]
\usemodule[amsl]
\starttext
\startformula
\frac{dy}{dx}\Big|_z
\stopformula
\stoptext
In MkIV, you don't need the newmat module and amsl module is
deprecated in both MkII and MkIV.
\starttext
\startformula
\left.\frac{dy}{dx}\right|_z

MkIV has a different column mechanism controlled by gridsnapping and
\bigg is pretty big in that case
Anyhow, there is no grid=no in itemize, at least not now, so you can use:
\setupmixedcolumns
[itemgroupcolumns]
[grid=no]
However, we can do this too:
\unprotect
\setupmixedcolumns
[\s!itemgroupcolumns]
[\c!grid=\itemgroupparameter\c!grid]
\setupitemgroups
[\c!grid=\v!tolerant]
\protect
After which we can say grid=no so I'll add that.

Hey list,

\stopformula
The location for the \Eulerconst just shows up blank with nothing there,
so I am assuming this is the wrong command. I am using ConTeXt
2012.11.16 under Ubuntu Precise.
You need a font which has the symbol, e.g. Cambria or Lucida OT.
In addition, the following formula does not typeset correctly. There is
no arrow linking 't' to infinity symbol:
\placeformula[formula:Limit of Verhulst equation]
\startformula
\math{\lim_{t\to\infty} P(t) = K.\,}
\stopformula
Works for me (Version 2012.11.23).
BTW: Why do you use \math inside of \startformula because it’s the command for
inline math in normal text?

[NTG-context] Odd bug with \startitemize
For some reason I used someone's earlier posting to test something about my tex
software and accidentally happened upon this odd behavior. If the
\startitemize code below is repeated 10 or more times, either with \dorecurse
or by pasting it ten times, only one is typeset. If nine times, then all nine
are typeset. If Some text is un-commented, then all ten are typeset along
with Some text. (If working with the pasted version, the Some text can
appear after the first or second iteration, or before any iteration that
appears on the first page, and all itemizations will appear.)

Re: [NTG-context] \startitemize[columns] once again...
Hi Marcin,
I think there is a small bug with itemize and columns: in another thread (with
Subject « vertical alignment problem in column items» ) Dalyoung reported also
an issue, which is related to what you have observed.
Please see my message in a reply to Dalyoung's message, where I reported some
testings but I am not sure when this bug appeared (in mkii, the behaviour is
essentially correct).

Re: [NTG-context] vertical alignment problem in column items
Hi Dalyoung,
I think that there must be a small bug in mkiv regarding itemize in columns,
but at the same time I think that the problem comes from the fact that in your
example you use inline maths and fractions: this perturbs the way the
horizontal and vertical distances are calculated by mkiv. It seems that mkiv
considers there is not enough horizontal space to put the four items in a row.
If you use two columns the problem is solved, as you can see in the following
examples (please typest it both with mkii and mkiv to see the differences).
Best regards: OK

If we remove the percentage signs in the items, an additional vertical

Hi, could anybody look into it? I tried also \smash-ing the formulae -
with no luck.
Hi Marcin, appears like the vertical spacing is extended when
content of the item exceeds the line height. The behavior is not
restricted to math mode, though I can’t say if there is an
official way to prevent or customize it. If you are desperate to
get around it, maybe put the content in a box of fixed height.
with the old context of current TeXLive it works without
adding additional space.

suspicion that \startitemize[columns] is again the culprit.)

Re: [NTG-context] using variable for subscript in math+lua
Thanks to all who gave a nice solutions.
To write a big matrix of unknowns A=(a_{ij}) is not a frequent case.
In math, there are many occasions to write matrices which need some typing
work like
\NC 2 \NC 3 \NC 4 \NR
So if we have a function which write a matrix when the data is given as a form
of table in Lua.
There are other benefits.
Sometimes, we may have to write a series matrices which are the results of the
some row operations in matrix.
We can also handle it conveniently because we can do some calculations in Lua.
If there is a way to convey some table data from ConTeXt to Lua, it would be
more convenient.
Here is an example which I did by your help.
I hope that you experts can make it more useful.
Thank you again.

[NTG-context] \abovedisplayskip and \belowdisplayskip
It is my understanding that \abovedisplayskip and \belowdisplayskip should
adjust how much (rubber) spacing that is allowed between display math
formulas. I have attached a ConTeXt file (bug.tex) that seems to indicate
that setting these skips does not affect this (rubber) spacing. I have
also translated this ConTeXt file line-by-line to a LaTeX file (bug.ltx)
and attached it.
Both files produce a PDF (using `context bug.tex` and `pdflatex bug.ltx`)
in which the spacing between the formula changes from page 1 to page 2
simply by adding the final formula. However, by changing \adjustdisplay{0}
to \adjustdisplay{1}, the LaTeX file produces a 3 page document where the
spacing between formula does not change (as expected) on the first two
pages and thus requires a third page to typeset the final formula.
However, making this same adjustment in the ConTeXt file does not seem to
affect the output.
I would appreciate any thoughts as to why this is happening, and I would
equally appreciate a solution to keeping the spacing the same in the
ConTeXt file and thus bumping that last formula to a third page.

Marcin Borkowski mb...@wmi.amu.edu.pl napisał(a):
Hello,
I encountered a weird problem with
\startitemize[columns]
Namely, sometimes ConTeXt (MkIV) puts a pagebreak before the
itemization. I tried to distill the problem to a minimal example,
until now without success, but I'll post a ME if I'm able to reproduce
a problem in a small file.
OK, so I didn't succeed in isolating this problem. I attach the
complete file (it's in Polish, sorry;)). The problem appears at page 3
in the resulting pdf (line 141 of the source file).
Anybody encountered this, too? Are there any solutions/workarounds
known?
I naively tried putting \page[no] in various places around the
problematic line, but to no avail. Also, while trying to isolate the
problem, for instance by removing things before the itemization, it
turned out that it's difficult to reproduce it: often, everything is
fine (at the beginning of the page as well as near the end).
Any ideas?

In this case \int and \sum are of the same size, so it appears as a
design choice, and more importantly, we can patch the font to change
DisplayOperatorMinHeight.
It's really weird ... in the virtual font builder we have
DisplayOperatorMinHeight = t . math_operator_size. text_style
and there has been a good reason for this otherwise it would not be
there. For the normal (12pt) size this becomes 1040448 for px as well as
tx. Both fonts (when looking at them with \showfont[pxex.tfm] etc have
the same shapes.
Concerning the rest of the parameters, only for this case irrelevant
differ a bit.
% name px tx
% RadicalRuleThickness 46399 44040 2359
% FractionDenominatorDisplayStyleGapMin 139197 132120 7077
% OverbarVerticalGap139197 132120 7077

% OverbarRuleThickness 46399 44040 2359
% StackGapMin 139197 132120 7077
% RadicalVerticalGap57998.7555050 2948.75
% StackDisplayStyleGapMin 324793 308280 16513
% AccentBaseHeight 353107.968 353894.4-786.4320003
% FractionRuleThickness 46399 44040 2359
% FractionDenominatorGapMin 46399 44040 2359

% UnderbarRuleThickness 46399 44040 2359
% RadicalExtraAscender 46399 44040 2359
So, there is no real reason for px to behave different than tx. However,
when we nil DisplayOperatorMinHeight we get the scaled glyph. Okay, we
could have threshold issue but even putting some real large math mess
after itm it will not bump to the next size shape (there is only one
larger size btw) .. puzzling
BTW, what is the status of Pagella Math? Should we default to that
instead of px-fonts?
not yet

Better is to use: \StrikeMeFrame{\mathsurround\zeropoint$#1$}. But for

Re: [NTG-context] Fonts in Mk IV -- \definefontalternative documentation?
Hello and welcome to the world of ConTeXt!

The best way to get started with fonts is probably the simplefonts module. I

for, so far.
Installation:
Run

Hello, I am coming to ConTeXt from LaTeX and have a typescript question. I
was searching for information on the mailing list about defining semibold and
other font variants, and found the following. Can you tell me if further
information is only available in the book context mkiv -- Fonts or can I
find it
somewhere else? I have searched through the revised Fonts chapter of the
ConTeXt manual but the \definefontalternative macro and the approach
described here are not documented there.
The approach below works for me if I adapt it to Adobe Garamond Premier
Pro, but I am attempting to build a typescript for that handles optical
weights,
small caps, etc and I have not been able to make it work yet.
Before I try posting a minimal example, I would like to be sure that I am
looking at the right documentation. I have looked at the Fonts in LuaTeX
page on Contextgarden as well, but I don't think I have a full understanding
of typescripts using OSFONTDIR fonts yet. If there is something I am missing
please let me know.
Thanks,
PPN
Based on ideas from the forthcoming book context mkiv -- Fonts:
% note: I have deleted all lines except the relevant ones for defining
% the semi bold alternatives

[NTG-context] \unit problem
Hello all,
It seems that some unit combinations don't work very well with the \unit
macro. I have some problems with the m- (milli-) prefix but some tests reveal
other strange errors.
Here is a not so minimal example. The first 33 entries come from phys-
dim.mkiv and work well. In the entries 100 to 115 which I added, the 102,
107, 108, 109, 110, 111, 112 and 115 cause problem :

Use text mode fractions! \frac{1}{40}.
This is still typeset in math mode. A alternative is to write the fraction as
“1/40”.

XITS, but you will get output as you describe below, which I know is
buggy since the font lacks generalised frac feature.

Looks like frac here is a simple ligature of few predefined fractions.

Re: [NTG-context] math signs in itemize
Thanks all, for your reactions.
I tried them all, but the process still stops at the \frac, which I changed now
into \frac{1}{40}, whatever I do.
The gentium font does not load properly; the file is typeset in Times instead.
I get these strange references to gentium instead.

Robert

Re: [NTG-context] beta
Hi Hans,
Just out of curioisity I tested your example, but mkiv stopped with the error:
! Undefined control sequence.
system tex error on line 14 in file units-math-export.tex:
Undefined control sequence ...
l.14 $10\su
{km/h}$
Probably I am being somewhat dumb… since the module « dimenesions » is not
present in the minimals. Has one to define \su somewhere?
I am reporting this upon using ConTeXt ver: 2011.06.09 12:49 MKIV.
Best regards: OK

I might decide to push it in the core. The su is an abbreviation for
scientific unit as we already have \unit (which I like more) and \dim is also
taken. Of course \u would be even nicer but that's a accent placement (ok, we
could drop all those as we have utf). Using two character names is not handy
as they look like language switches.

In addition, I think AMSTeX defines a command `\DeclareMathOperator` [1]

[NTG-context] Context and metapost: using \frac
Hi
I am using context to run a metapost graph. I am however unable to
insert a label with \frac, since this is not pure Tex but Latex. This
seems to be a known problem for metapost:
-Seems for metapost only, one should add %latex
(http://ryanmlayer.wordpress.com/tag/metapost/).
-I saw also one post where it was mentione done should add
//\setupMPpage[offset=1pt]
//(http://www.tug.org/pipermail/pdftex/2001-March/000429.html). I tried,
but did not work however...
Any idea how I should do? Find below minimal example, that does not work
on my computer when compiling with context...
Thanks!!
Matthieu
\starttext
\setupMPpage[offset=1pt]
\switchtobodyfont[10pt]

\startMPpage
label.top(btex 1.4 etex scaled 1.00, (10, 10));
label.top(btex $\sigma_t$ etex scaled 1.00, (0, 10));
label.top(btex $\displaystyle \frac{\sigma_t}{a}$ etex scaled 1.00,

Re: [NTG-context] Grid typesetting and inline math
After some trial and error, I'm using
\setuplayout[grid=yes]
\startlinecorrection
Paragraph with inline math
\gform{math stuff} % without the optional [-]
and some more text that belongs to this parapgraph
\stoplinecorrection
and
\blank[-1*line]
where necessary. It is not really a convenient solution, but it works
and I've got the impression that I can do what I want.
Again: Does anyone have a better solution or advice regarding grid usage?

Hello,
I'm struggling with the grid. I've stepped from LaTeX to luaLaTeX for a
simpler font selection, and from luaLaTeX to ConTeXt for getting a
usable grid (because I was told that it supports typesetting on a grid).
Now that I got font selection working as desired in ConTeXt, the grid is
driving me crazy.
I'm trying to use the grid as described in details.pdf, and I want
halfline spacing around formulas in text, because a full line is
definitely too much. This is what I'm compiling:
\setupbodyfont[10pt,serif] % should be lm?
\setuplayout[grid=yes]
\setuptextformulas[step=halfline]
\starttext
\showgrid
Testing inline math: \gform{x_2 = \frac{a}{b}}. The following line
should be seperated from this one by half a line, but it isn't.
Testing inline math: \gform[-]{x_2 = \frac{a}{b}}. The following line
should be seperated from this one by half a line, but it isn't.
\stoptext
Both paragraphs look identical, the second line is too far away from the
first one. What's wrong with my code?
Also, how can I manually depart from the grid, e.g. for block quotes?

Thanks for answer!
Is this code you wrote supposed to be the whole doc to compile? And
compiled with context? If yes, I got an error again... I have version
context --version
MTXrun | main context file: /usr/share/texmf/tex/context/base/context.tex
MTXrun | current version: 2009.11.26 16:2
Is it likel;y then that the problem is solved in more recent versions? I
would try to update then... I am on Ubuntu 10.10 64b, is there a simple
way to update from other repos, or should I compile?
Thanks for your help!!!

Morning all,
I have a need to write a lot of physical quantities - these should be
in text mode. Mostly I can manage, but subscripts are causing me grief
Eg
\startformula
\startmathalignment[n=3]
\NC \text{F}\NC =\NC {\text{GMm} \over \text r^2}\NR
\NC \text {force}_G \NC =\NC {\text{G} \times \text m_1 \times \text
m_2 \over \text r^2}\NR
\NC \text {force \low G} \NC =\NC {\text{G} \times \text m_1 \times
\text m_2 \over \text r^2}\NR
\stopmathalignment
\stopformula
In the second and third equantions I'd like force subscript G all in
roman, not italic, to follow the standard conventin.
The first one puts the G in the correct place, but in italic
The second one manages roman, but it's offset.
Is this ok?
\text{force}_{\rm G} (or \text{force}_{\text{G}})
With \rm you stay in math mode, but use roman. You should not use \rm
for force since you would get mathematical spacing instead of proper
kerning.
\startformula
{\forceQA \over \massQA} = \accelerationQA
\stopformula
Try to use \frac{}{} instead of \over. There are discussions about
disabling \over in luatex (or at least in MKIV).

Re: [NTG-context] odd end-of-line error w/ Minion Pro
Am Freitag, 11. Februar 2011, um 09:26:59 schrieben Sie:
Hi,
I'm seeing a strange behavior with Minion Pro in OTF and the simplefont
package. I'm not sure if it only happens with simplefont because I don't
know how to set up a typescript. In any case, in breaking a line between
roman and italic text, ConTeXt is losing a bit of space at the end of
line. I thought it might be related to using hz or hanging alignment, or
the quality option for protrusion and expansion, but it seems to happen
even with these features disabled. Very unclear what could be causing
this. Is it a known issue? What is this kind of bad behavior called?
I've attached an image to which I've added a red line to show where the 'a'
is leaving extra space before the newline.
Thanks again,

If I recall correctly there a way to see the in the log.
Depends on the commands, sometimes the value is checked but no with
gridsnapping.
The “yes” value is defined as
\definegridsnapping[yes][maxheight,maxdepth,strut]
and you enable with with “grid=yes” a where context tests if “yes”
is a predefined lists but “grid={maxheight,maxdepth,strut}” is also
valid and in this case context defined a dummy list which is passed
to lua. The same happens with “verytolerant”, context creates
a dummy list and use ”verytolerant” as value for this list.
Thank you Wolfgang!
Now I've defined verytolerant in order to get some fractions on grid.

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

I think one should use \overline instead of \overbar in your example. For me
the following works fine with mkiv:
\starttext
\startformula
\overline{q} = \frac{\overline{q}}{\overline{α_0}}
\stopformula
In text $\overline{q} = \frac{\overline{q}}{\overline{α_0}}$.
\startformula
\overline{q_0} = \frac{\overline{q}}{\overline α}
\stopformula

(one gets as expected the « conjugate » of α_0, for instance).
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.

[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
