Re: [NTG-context] Formulas include chapter number
Hi Marco, It's a bug, I think. The keys that control this are way and prefixsegments: \setupformulas[way=bychapter, prefixsegments=chapter] way=bychapter means 'resume numbering at each chapter' prefixsegments=chapter means 'precede each formula number with the chapter number': chapter.formula Right now, as soon as I set 'prefixsegments' to 'section' or 'chapter' or a number, the prefix segments disappear. Ditto when I set 'way' to anything. This suggests that it is a bug. Is it indeed, Hans? I've attached a test file for you. You can use \setupformulas[prefixsegments=] to solve your problem if you never want prefixes; that also specifies the correct behaviour once the bug is fixed.

The units code doesn’t know how to deal with “N” but you can use the full name
of the unit (can also be lowercase) or “n” which is also accepted.
\starttext
\startformula
a = \unit{210 kilo Newton}

[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}
\stopformula

Since I use ConTeXt to typeset math formulas frequently, I want to
know more about this. Why \AA doesn't work?
\AA is defined in plain TeX, and I think all plain TeX macros should
work in ConTeX. Am I right ?

Yes. Some of them show examples of MathML code and how

[NTG-context] Known nath bugs?
Hello all,
is there a list of know nath bugs somewhere on the web? I tried to find
one using Google, but unfortunately without success.
The reason I'm asking this is that I'm encountering some problems with
the module and would like to know if they are common or if it's related
to my configuration. First of all, using the units module together with
nath doesn't seem to work - for instance, $1\Micro\Coulomb$ works as
expected without nath, but produces the error message "Please don't say
\def cs{...}, say \def\cs{...}" when used together with nath. I also
thought that delimiters like ( or [ should automatically adjust to the
formula they contain, but (\sum_{something}
\frac{something}{something}) only produces standard parentheses.
Commands like \lbrace or \lbrack work as expected, though.
If these problems are unknown, I can post a small example file and my
logfile.
Best regards,
Sebastian

Uh-uh. The problem is clear: \inlinemath tries (in the definition of
\inlinemath@) to expand the formula (in the sense of TeX macro
expansion). \longrightarrow cum suis are, however, not expandable in
ConTeXt.
Now, I do believe the xdef is a bug in nath, but the following
workaround does work:
\protected\def\longrightarrow{\relbar\joinrel\rightarrow}
Hans, do you have a command that sort of changes an existing definition
as if \protected had been used in the first place?
first of all, \protected is not what you think it is; i had a \protected before
etex was around; the context name is \unexpanded
\let\unprotectedlongrightarrow\longrightarrow

Re: [NTG-context] Updated math modules
Hello Giuseppe,
Thanks for your good work. Sorry for reminding this bug to you, but it's
the only reason why I can't use nath even though I wish a lot. About the
problem unicode characters in toc.
Ref.: http://www.ntg.nl/pipermail/ntg-context/2004/005306.html
I attached a minimal example unicode file. You'll get garbage instead of
the expected the "e acute" on the word "MathÃmatiques" in the table of
contents.
No matter wheter I use the amsl module or not, I get the following entry
in my tuo file:
\listentry{section}{1}{1}{Math^^c3^^a9matiques}{2::0:0:1:0:0:0:0::1}{1}
Moreover, if you replace [nath] with just [amsl], you'll get different
alignment of the formula.
BTW: my TeX doesn't seem to like DOS-style newlines in t-amsl.tex, so I
had to convert them to Unix-style ones.

[NTG-context] Wrong prefix in cross references to formulas in external document
Dear Hans and all contributors,
I really appreciate ConTeXt for the right way to obtain high quality
documents. I'm a theoretical physicist and I'm going to write a book. I
think ConTeXt is the right choice to work with a number of formulas,
figures and cross-references. The visual quality of formulas is better than
in regular LaTeX. The new feature with formula autosplitting looks also
very promising. For me it is important to obtain the high quality without a
lot of manual tweaks of each formula for each given document format and
figure placement.
However, I have found a problem with references if I compile one component
only. The references to formulas in other components have wrong prefixes,
e.g. (2.1) instead of (3.1). Needless to say, the right formula references
are very important.
I started looking into this issue. The references to other components are
taken from the whole product as from an external document. It turned out
that this is a general problem with references with prefixes to external
documents. The prefix is stored in a tuc file as a reference to a section
as a sequential number of the header in the document. As a result, the
prefix from the external document is calculated using the structure of the
current document.
Here is the MWE, which consists of two files:
foo.tex:
\defineenumeration[remark][prefix=yes, prefixsegments=chapter:section]

Chapters: \in[foo::chap1], \in[foo::chap2], \in[foo::chap3], \in[foo::chap4]
Remarks: \in[foo::remark1], \in[foo::remark2]
% any chapters and sections here
\stoptext
It is expected to have the same first page on these documents:
Equations: 1.1, 2.2, A.1, A.2
Sections: 2.1, 2.2, A.1, A.2
Chapters: 1, 2, A, B
Remarks: A.2.1, A.2.2
However, the bar.tex produces wrong prefixes to formulas and remarks. The
output depends on the document structure of bar.tex, not foo.tex.
I started looking into the source code. Thanks to lua, it is not a big deal
to track the problem. The prefixdata is complemented by the sectiondata
after the loading the tuc file. So, the question is: is it possible to
store the full prefixdata with all necessary prefix numbers in the tuc
file? Here is my proposal to change the source code:

Somewhere in the math formula just ended, you used the stated character from an

[NTG-context] Re: can we do binding correction?
There is some mention of a mechanism to get binding correction from an old
article in the wiki about emulating the Koma TypeArea from LaTeX, you can
see it in https://wiki.contextgarden.net/KOMA-scrartcl_Type_Area
There is also some discussion about the subject in SE:
https://tex.stackexchange.com/questions/38682/rules-of-thumb-for-size-of-binding-correction-bcor
However, that discussion is 12 years old and the links referenced as
sources are dead now.
I have found with experience that a formula to calculate the binding
correction for a saddle stitch binding, not more than 4 pages in a
signature (only one fold in the middle) usually is 1/2 the circumference of
a circle with radius *r*, being *r* the thickness of the paper times the
amount of physical signatures. Something like: \frac{π \times t \times
s}{2}. I have not tried a formula for more folds in a signature.
The thing is, you have to recalculate for each signature fold. The
innermost will have displacement zero, the second one a little bit more,
the third a little bit more, and on and on until we reach the outermost
signature.
However, it is necessary to say that unless you are using a
particularly thick paper, or you are using too many pages for a saddle
stitch bind (my personal and professional opinion would be no more than 80,
but better 60), the displacement is usually negligible.
For example, let's say the paper thickness is 0.1 mm (which is 0.0001
meters) and there are 40 pages in 10 signatures. The radius would be 0.0001
meters per signature * 10 signatures = 0.001 meters. Then, half the
circumference would be 1/2 * 3.14159 * 0.001 meters ≈ 0.0016 meters or
1.6mm at the last signature. Unless there was a displacement of more than,
say, 4 mm, I wouldn't worry too much about it.

but this fails for obvious reasons (as would using `$$' instead of
`ensuremath' in the `latex' case).
so what I need is a way of defining (potentially complex)
math-expressions via some shortcuts/definitions/macros/abbreviations
(whatever) which I can then use
in the formula environment (or whatever it's called in `context'...) as
well as in the body text.
any help appreciated,
In ConTeXt you have to write
\define\km{\mathematics{K_m}}
but there is not much to gain from this because you can enter math mode
in the text with \m{…}.
thanks for the response. in my silly example you are right (but even there
it saves more than 50% of keystrokes). but I'm thinking of course of more
tedious math expressions where it rapidly is handy to use such
abbreviations -- the more so, if you have, say, 20 different ones
appearing repeatedly in the document. but that would work with the
`\def..\math' construct in the body text. what does _not_ work, then, is
to use the definition in a display (\startformula...\stopformula) equation
(which it _does_ in latex when isolating the math expression with
`ensuremath'). so my real question(s) are:
1. is there any way to achieve the same functionality in `context'
(expansion of math-containing defintion/macro/abbreviation in text _and_
math environment? if yes, how would I do this?
2. if no, would it be sensible (and feasible) to modify `\math' behaviour
and to make it aware of whether it is called from within text or from
within a display equation (in which case it should do nothing...), i.e.
mkae it behave like `\ensuremath' in latex?

So, if I want to get structured xml file I need to either redefine all
usual command to be tagged (start/stop) and, that is more logical define
my own tag commands. IMHO the use of 'important' as in example above is
logical, the actual presentation of 'importtant' words could be define
separately and in different ways (I like idea of xml+styles).

E-er, yes. I don't see characters (my terminal use UTF8 and good font)
even now. But I saw them in web intterface to ML (contextgarden because
another shows something different). Also I saw tthem in Emacs. AFAIU,
this is in private region of Unicode, these are _italic_ E, m and c. I
thought that there should be letter from ASCII (codes < 127).

Well, this were simple tests. I'll make more complex one in next weeks.
Texts, with font switching, maths, images, tables. I want to have tool

Latex is not all that bad :) It has \textsuperscript and

The wrapping in \hbox is not that bad. A lot of math trickery happens
inside a \hbox. The example on contextgarden
(http://wiki.contextgarden.net/Bold_Math) is not too different from
how bm.sty implements bold symbols in latex (which is the best bold
math implementation in latex, AIUI). However, the \boldmath definition
on contextgarden lacks
1. Use of pmb (poor man's bold) when a true bold character is not
present. \boldsymbol{\sum} does not work.
2. Does not take care of the math spacing
\formula{ a \boldsymbol{=} a } does not look correct.
3. Does not take care of delimiters
\formula { \boldsymbol{\left(}\frac 1n\right)} does not work.
4. bm.sty goes into some trouble to define bold accents. So
\bm{\hat}{a} produces a bold accent over a non-bold a. (I can not
understand why would someone ever use that).
Hans, why is [boldmath] not defined by default in all the typescripts?

It can be used everywhere. For example
\def\myrmbf{\boldmath\rm\bf}
{\myrmbf How to loose a guy in $10$ days}
It will be nice if one could write
\def\mybf{\boldmath\previousfont\bf}
Maybe what is needed is a \beforemathswitch token set. Then one could
do
\appendtoks \boldmath to \beforemathswitch

[NTG-context] Unconnected \mathboxanchored produces unexpected results

I got an unexpected result when I asked for a \mathboxanchored, but then did
not use it with a connector. I expected the \mathboxanchored contents to be

[NTG-context] strange output in math display mode
Dear Hans,
After updating the minimal, I got a strange output of math display mode.
Would you please check it?
Here is an example.
Best regards,
Thank you.
Dalyoung
\starttext
Here is a strange output of math formula. It is displayed correctly in text
line, but is displayed strangely in math display mode.
\blank
Here is a correct output in text line. $\int_0^t B(s)\ dB(s) = \frac{1}{2}
B^2(t) - \frac{1}{2} t.$
\blank
But in the output of display mode, the location of the sub- super-script of the
integral sign is not normal and the output of \type{ \frac{1}{2} B^2(t)} is
wrong.
\startformula
\int_0^t B(s)\ dB(s) = \frac{1}{2} B^2(t) - \frac{1}{2} t.

Re: [NTG-context] Strange behavior with Utopia fonts in math mode
Fabrice Couvreur <mailto:fabrice1.couvr...@gmail.com>
17. April 2016 um 11:16
Hello,
I compiled this file with a strange exit for mathematical formula.
What do you mean with "strange exit"?
What's missing in my file ?
You get the necessary font when you use the "--fonts=mathdesign" for
first-setup, e.g.
sh first-setup.sh --fonts=mathdesign
and your example can be reduced to (you can drop encoding=...)
%% begin example
\loadtypescriptfile[mathdesign]
\definetypeface[mainface][rm][serif][palatino] [default]
\definetypeface[mainface][ss][sans] [helvetica][default][rscale=auto]
\definetypeface[mainface][mm][math] [utopia] [default][rscale=auto]
\setupbodyfont[mainface,12pt]
\starttext
\input knuth
\startformula
f(x) = \sum_{i=1}^n a_i x^i
\stopformula
\stoptext
%% end example
There are a few mistakes in the output because the mapping from glyphs
to unciode
values for the math font has to be improved.
Wolfgang

Hi,
Maybe you should use rather
$\underbar{F_C=\unit{1e2 newton}}$ or \underbar{\unit{1e2 newton}}
since otherwise \underbar considers each character in the math formula as a
word, which should be underlined separately.

[NTG-context] White Space after \startalign
Dear all, I have noticed a new problem in the \startalign environment recently. \startalign adds whitespace after the formula. If I remove the *\NR* from the last equation then the white space disappears. But I need to keep it for numbering the last equation. In any case, I thought that the last *\NR* is required in the *math align* environment. I remember getting errors for not including the last \NR when I was just starting out with ConTeXt. May be something has changed or my memory is not quite what I thought it was. Please let me know if I am making a silly mistake.

Now if I use for example Termes as the math font, the formulae don't match the regular text, because the letters and digits differ. That's why I want in the formulae math symbols like special arrows and operators to be taken from Termes, but regular alphanumeric characters from my text font. So in my minimal examples, "123" should look the same in the text and the formula.

[NTG-context] How to place a verbatim environment in the text such that the following paragraph is not indented?
Dear list,
how do I place a verbatim environment in the text such that the

--- minimal example ---
\starttext
\setupindenting[1.3em]

frame=off,
bottomframe=on,
topframe=on,
background=screen,
backgroundscreen=.95]},
after={\stopframedtext},
bodyfont=9pt,
margin=1.3em]
\input ward
You can use the following syntax
\startR
f <- function(x) x^2
\stopR
to define a function. (Begging of line should not be indented.)
\input ward
Have a look at
\startformula
f(x) = x^2
\stopformula
where $f$ is a function. (No indent as expected.)

Hi Uschi,
I don’t know whether this is similar to whay you might intend:
\setuppapersize[A8,landscape]
\setuplayout[leftmargin=2.5cm,
leftmargindistance=0.2cm,
backspace=2.9cm,
width=4cm]
\showframe
\starttext
\blackrule
\margintext{\blackrule[color=black, height=0.5ex, width=1cm]\\Me}
\startformula
a^n + b^n = c^n.
\stopformula
\stoptext
BTW, it isn’t also clear to me whether the formula is part of your
document or not.
Just in case it helps,

Dear list,
According to the information on contextgarden (section chemistry)
chemical reactions should be entered as follows:
\usemodule[chemic]
\startformula
\chemical{CaCO_3(s),+,HCl(g),->,CaCl(HCO_3)(s)}
\stopformula
That produces a formula with the comma's in it, so that's not good. If
I enter it as follows
\usemodule[chemic]
\startformula
\chemical{CaCO_3(s) + HCl(g) \rightarrow CaCl(HCO_3)(s)}
\stopformula
Then somehow after the \rightarrow the math/chemical environment is
lost and the remainder gets typeset as text. The same is true if I use
any math command such as \beta or \cdot.
The closest I get to the desired result is with the following:
\usemodule[chemic]
\startformula
\chemical{CaCO_3(s) + HCl(g) -->
CaCl(HCO_3)(s)}
\stopformula
But that is a bit of a compromise.
Regards, David van Diepen

Mehdi Omidali wrote: Hi If you run \starttext \startformula V) V\exists F\exists \stopformula \stoptext the space between V and ) for example is not correct.

(if it did, operators like "sin" would come out badly). Instead, it relies on ordinary inter-glyph kerning. I am not at all sure what the best solution for this is, as I have no idea how MS Word differentiates between the formula above and 'multi-letter identifiers'. Perhaps luatex should look at the \catcode of the characters in question? Or perhaps these inter-char kerns actually exist in Cambria?

Hans now uses OpenType Math (sometimes faked) fonts always, and his

I thought this had been fixed a few weeks ago.
I am using a month old version. I'll update and check again.

[NTG-context] Euler Constant and limit
Hey list,
I am trying to typeset the Verhulst equation which contains a Euler
constant which I cannot get to display correctly:
\placeformula[formula:Verhulst equation]
\startformula
\math{P(t) = \frac{K P_0 \Eulerconst^{rt}}
{K + P_0(\Eulerconst^{r t} - 1)}}
\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.
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
PS Please cc me, as I am not on the list currently.

Hello Florian,

your example :) :) :)
Do you need "a umlaut" or do you need a double differential (d^a/dt^2)?
I just wanted to say that if you need ä as "a umlaut" in formulas, you
would probably want to use $\text{bär}$ rather than $\rm b\ddot ar$ in
such cases. But if there's indeed a problem, it needs to be fixed
anyway.

Thanks Taco!
The normal setup for section header is before=\blank[2*big] and
after=\blank
I wonder, why "\blank" is stretching, but not \blank[2*big]... ?
With LaTeX, I had really good experience: all vertical spaces stretch in
the right proportions and a big float alone on a page gets centred.
Now I would like to achieve the same with ConTeXt, but I'm frightened about
spending days to find the right combination of \vfil, \vfill and \vfills
around every head, formula, float, description, paragraph etc etc...
Ok, if there is no easy way, I will try all "before=" and "after="
possibilities.
Or should I better play with \topskip and other such skips (which ones?) ?

yet another option is to 'normalize the file' by preprocessing
this is something that needs discussion

however, better si to use
\usemodule[newmml] % soon thsi will be the default
\usemodule[MathML]
^^ mathml
\useXMLfilter[mml,mmp,mmc] % basic mathml/presentational/content
this is then not needed! (the mathml module does this)

[NTG-context] Breaking large equations across pages
Pagebreak of formula across pagebreaks is broken in the new release
(ConTeXt ver: 2006.04.27 15:59).
Consider
\starttext
\placeformula \startformula \startalign
\dorecurse{50}
{\NC a \NC = b \NR[+]}
\stopalign \stopformula
\stoptext
(This used to work earlier, I can not test this, but I have document
where the display broke across pages. Can somewith with an old ~ Mar,
2006 release test this?)
Also, is it possible to have more control over where the display
breaks. With latex, I can force equation break by using
\allowdisplaybreaks[1|2|3|4]
\documentclass{article}
\usepackage{amsmath}
\allowdisplaybreaks %< Try with and without this.
\begin{document}
\begin{align}
a &= b \\
% Paste the above line 50 times
a &= b
\end{align}
\end{document}
Ideally, context should also provide something configurable. Maybe, it
should be part of
\setupformulas[displaybreak=tolerant|verytolerant|strict|verystrict]
Also there should be something like
\NC \NR
\allowdisplaybreak[yes|no|disable...same meaning as in \page[]
\NC . \NR
to have more control over the pagebreak.

Something broke with formula numbering, and it is due to the numbering
changes. \preparethenumber is commented from core-sec.tex,
dododoformulanumber in core-mat.tex still uses it. As a result even
the simple
\placeformula \startformula a = b \stopformula
fails with
! Undefined control sequence.
\dododoformulanumber [EMAIL PROTECTED] \preparethenumber

l.3 \placeformula \startformula a = b \stopformula
Changing preparethenumber in dododoformula by preparefullnumber gets
rid of the problem.

Hi Aditya,
this was new to me.
You are right, this did work as expected but only when you place the
definition of the abbreviation and the \placebookmarks command in the
right order.
The following order in the souce works.
\abbreviation [UK] {UK} {United Kingdom of Great Britain and Northern
Ireland}
\placebookmarks[chapter,section,subsection]
The problems is, the token register \simplifiedcommands is called by
the \placebookmarks command and every abbreviations, that follows after
the command is ignored.

I use

left & right & \formulanumber \cr
}
or
\eqalignno{
left & right & \formulanumber{a}\cr
left & right & \subformulanumber{b} \cr

If I have a longer formula which should only get one number, I use
\eqalignno{

}

[NTG-context] 10+ reasons why I still use MKII
Dear Hans,
since you have promissed another hotfix release for TL 2010, here's a
list of issues that I had with my thesis and MKIV (some have already
been fixed in the due time, but many remained). I probably wouldn't
have had those "problems" if I was designing my document in MKIV from
scratch, but just recompiling in MKIV didn't work out for several
reasons listed below.
1.) Minimal example:
\usetypescript[iwona]
\setupbodyfont[iwona]
\starttext
$a+b$
\stoptext
Output:
!define font: font with name Iwona-Math-Letters-Regular is not found
!define font: unknown font Iwona-Math-Letters-Regular, loading aborted
!define font: unable to define Iwona-Math-Letters-Regular as
\*iwona6ptmmmr33*
!define font: font with name Iwona-Math-Letters-Regular is not found
!define font: unknown font Iwona-Math-Letters-Regular, loading aborted
!define font: unable to define Iwona-Math-Letters-Regular as
\*iwona8ptmmmr22*
!define font: font with name Iwona-Math-Letters-Regular is not found
!define font: unknown font Iwona-Math-Letters-Regular, loading aborted
!define font: unable to define Iwona-Math-Letters-Regular as
\*iwona11ptmmmr11*
!define font: font with name Iwona-Math-Letters-Regular is not found
etc. I need to figure out why, though it works (I don't see
deficiencies in output yet).
2.) Recently discussed on the mailing list - stopper has no influence in MKIV:
\setupcaptions[stopper={:}]
\starttext
\placefigure{title}{\framed{bla}}
\stoptext
3.) Bibliography citations give different result with the same setup
(different numbers and different spacing in \placepublication - might
be also worth testing with grid typesetting as I wasn't able to set up
the alignment properly in MKII last time when I have tried). I'm not
sure which one is right, but there's probably no reason to produce
different results.
\usemodule
[bib]
\setuppublications
[alternative=num,
criterium=all,
sorttype=cite]
\starttext
\startpublication[k=a,t=article]\arttitle{a}\stoppublication
\startpublication[k=b,t=article]\arttitle{b}\stoppublication
\startpublication[k=c,t=article]\arttitle{c}\stoppublication
x\cite[a,b,c]
\placepublications
\stoptext
4.) The following problem must have appeared recently (it was working
ok in September): in MKII the encoding is completely screwed up:
\usemodule[gnuplot]
\enableregime[utf-8]
\starttext
\startGNUPLOTscript[integrated risetime]
plot sin(x) t 'šin(čix)'
\stopGNUPLOTscript
\useGNUPLOTgraphic[integrated risetime][1]
\stoptext
A slightly more basic example:
\enableregime[utf-8]
\starttext
\startbuffer[gnu]
\startMPcode
draw \sometxt{čšž};
\stopMPcode
\stopbuffer
čšž
\getbuffer[gnu]
\stoptext
5.) Weird formula number placement when long equations are used in MKIV
\def\oklepaj#1{\left(#1\right)}
\starttext
\placeformula
\startformula
{\dot N}(t)=
A\oklepaj{\exp\oklepaj{-\frac{t-t_0}{τ_{\text{eksp.-\exp\oklepaj{-\frac{t-t_0}{τ_{\text{fast}+
B\oklepaj{\exp\oklepaj{-\frac{t-t_0}{τ_{\text{eksp.-\exp\oklepaj{-\frac{t-t_0}{τ_{\text{slow}
\stopformula
\stoptext
6.) I know that \NR is not the most appropriate way to go into next
row, but the following gives considerably different results in MKII
and MKIV:
\starttable[|l|]
\NC \type{a} \NC\NR
\NC \type{a} \NC\NR
\NC \type{a} \NC\NR
\stoptable
7.) I know that there's a longstanding left vs. right bug, but
flushleft is no solution in the following case (compare MKII and MKIV
again):
\definedescription
[latexdesc]
[headstyle={\ss\bf},style=normal,align=left,location=hanging,width=fit,margin=0cm]
\latexdesc{step E (expectation):} \input tufte
\latexdesc{step M (maximization):} \input tufte
8.)
\definetypeface [boldmath] [mm] [boldmath] [latin-modern] [default]
\starttext
$\boldsymbol{\theta}$
\stoptext
9.) Note the big difference of when the formula starts vertically on page:
\starttext
\startformula
a+b
\stopformula
\stoptext
10.) Different square root shape/variant used:
$\frac{1}{\sqrt{2πσ_i^2}}$
Original formula:
\startformula
\startcases
\NC ρ_0, \NC for $i=0$, \NR
\NC
ρ_i\,\frac{1}{\sqrt{2πσ_i^2}}\exp\biggl(-\frac{\left(x_j-μ_i\right)^2}{2σ_i^2}\biggr),
\NC for $i\in\left\{1,2\right\}$. \NR
\stopcases
\stopformula
but I cannot reproduce the big difference it makes in original
document on a smaller scale.
11.) Missing bibliography entries:
\usemodule[bib]
% this line spoils the show
\setuppublications[alternative=num]
\setuppublicationlayout[webpage]{%
\inserttitle{\bgroup\it }{\egroup. }{}%
\inserturl{}{}{}%
}
\startpublication
[k=FAIR,t=webpage,u=http://www.gsi.de/fair/]

\title{FAIR -- Facility for Antiproton and Ion Research}

Hi,
Thanks Hraban for the information and the link to the article by Hans and
Mikael about the math fonts in Lucida.
I very much appreciated that article: one sees how the handling of almost
impercebtile details in ConTeXt make us to adhere to and love LuaMetaTeX… So a
great thank you to Hans and Mikael for all this work!
Regarding the details of vertical alignment in math, I wonder whether the
column « : » in front of the equal sign « = », in the combination « := » (used
to define for instance a new variable) should be alos centered around the math
axis, as explained in the article. For instance in the following example
\setupbodyfont[lucidaot,12pt]
\starttext
\startformula
f(x) := -(u|x) := - \langle u, x \rangle
\stopformula
\stopformula
\startformula
f : A \longrightarrow B
\stopformula
\stoptext
it seems to me that the lower dot (or square…) in the semicolumn of the first
formula (in front of the equal sign) is lower than in the second formula.
Best regards: Otared
Thank you for the kind words, Otared,
Regarding the colons (and other symbols with "dots"), I would say it
is still not optimal in Lucida (and difficult to make it "consistent",
there are too many symbols that are at the moment different). But in
your example you can use \colonequals and \colon if you prefer. They
are centered around the math axis.
Best, Mikael
\setupbodyfont[lucidaot,12pt]

There is a (experimental as we played with it and then got distracted)
feature that makes some symbols adapt to spacing in the input.
\starttext
\setupmathematics[autospacing=yes]
\setupmathematics[collapsing=2]
\im{A:B} and \im{A : B}\par
\im{A:=B} and \im{A := B}\par
\im{A\colonequals B} and \im{A {\colonequals} B}\par
\stoptext
the second line is not yet ok as collapsing the := (old feature) comes
at the wrong time when we do autospacing (something Mikasl and I now
need to discuss and test)
This autospacing is part of some larger effort, for instance we can also
auto handle fences and so. All this relates to minimizing the input and
make it a bit more natural. Think (1,2) vb (1, 2) where we - due to the
many more classes that we have - want spacing to be right.
All will be revealed in the upcoming releases and the upcoming 3145 page
math manual.

Re: [NTG-context] Vertical space around displayed formulas
Hi Hans,
Thanks for your attention which fixed most of the difficulties with vertical
distances around math formulas.
However, after typesetting a long document, I noticed that there are still some
incorrect behaviours. The following minimal example, extracted from that long
document, shows what is wrong: please have a look at the second formula in the
attached PDF. (The output with the older version from TeXLIve 2016 is correct).

Re: [NTG-context] startitemize bad with columns
By the other hand, the same with \startformula \stopformula makes that the
number of itemize is in one column and the formula in te other column.
How can I force that number of itemize and the formula will be in the same
column:
Simplifiqueu (potser sigui conveninent factoritzar el nombres més grans):
\startitemize[a,columns]
\item \startformula 5^{-3} \colon 5^4 \stopformula
\item \startformula (2^{3})^{-2} \cdot 2^{-3} \stopformula
\item \startformula \frac{(-4)^2 \cdot 2^3}{2^{-2}} \stopformula
\item \startformula \left(\frac{5}{2}\right)^{-3} \cdot
\left(\frac{2}{5}\right)^4 \stopformula
\item \startformula (-2)^{(-3)} \colon \left(\frac{1}{2}\right)^3 \stopformula
\item \startformula \left(\frac{5^{-3}}{2^{-3}}\right)^2 \stopformula
\item \startformula \left(\frac{1}{2}\right)^{-2} \stopformula
\item \startformula \frac{\frac{2}{5} \cdot
\left(\frac{2}{5}\right)^{-2}}{\left(\frac{2}{5}\right)^2} \stopformula
\item \startformula \frac{4^2 \cdot 2^3 \colon 2^{(-1)}}{2^{(-3)} \cdot 8}
\stopformula
\item \startformula \frac{2^3 \cdot (-2^4)^2}{2^{-5}} \cdot (-2)^3 \stopformula
\item \startformula \frac{(-2)^3 \cdot (-2)^{(-4)}}{2^5} \stopformula
\item \startformula \left(\left(\frac{1}{-16}\right)^{-2} \colon
\left(\frac{-2}{16}\right)^3\right)^{-3} \stopformula
\stopitemize

The thing is that the formal specification is not clearly defined, not even if you mention all cases. _You_ may not want indented footnotes, but _I_ have typeset a book that did. And consider this: Text text text text \startquotation Quoted text quoted text \stopquotation Text text text text is the next "Text" indented, yes or no? Whether this is a 'display' or a standalone paragraph is very much up to the document designer. In english mathematical texts, Theorems and such are often seen as a kind of run-in header, so that "Theorem 1. Text text text" is not indented, but that usually does not apply to "Proof. Text text text" and "Remark 1. Text text text": those usually _are_ indented. I am being hesitant about a 'global switch' because I fear that any automated solution only takes care of one particular set of settings, and so does will really help that much and will become a documentation nightmare. Imagine: The command \indentallparagraphs will make sure that every paragraph in the document will get indented, regardless of its surroundings, with the following exceptions: * the bodies of the predefined floating objects figures, tables, intermezzos, graphics. * the bodies of the predefined footnotes & endnotes, and floating marginals * the contents of float captions * the paragraph following a \stopformula, if that formula is not preceded by \placeformula, and there is not empty line inbetween. * any itemgroups, enumerations, descriptions, floats etc. that were not predefined in the context core. * ... I hope you see the problem with that. Even a simple command like \setupindentnext[yes] does not work out-of-the-box, because you actually wanted \setupformulae[indentnext=auto] % not yes As I said before, it may be much easier to put all this in a module (by you, or someone else, but I guess you now have the list of desired commands pretty much at hand?). Then you can say \usemodule[indentall] and the context core would not have to think about all these border cases.

It's working and this is more than I can say from my first attempt. But
you are right. There is much room for optimization. I'll try to cook up
something new tomorrow and then send you the result.
Calculating in TeX can be so much fun ;)

[NTG-context] Bug in maths environment: thematrix
Hi Hans,
I noticed that in some situations the command \thematrix does not show all its

it will work if you configure the inner align to be tight (i delegate

\breakhere b = \text{something}
\breakhere c = \text{someother}

might be okay for your purpose

Re: [NTG-context] Issues with RGB to CMYK conversion with color profiles
Jan U. Hasecke schrieb am 14.11.18 um 11:39: Hi all, attached you find my colormanagement tests and I need your help to understand and debug the situation. I am testing together with a friend of mine, a professional colormanager, who does not know ConTeXt. Even without a color profile the results from the normal conversion of colors from cmyk to rgb can result in differences between ConTeXt and Gimp because both use different formulas. This is the formula from ConTeXt (attr-col.lua) r = 1.0 - math.min(1.0,c+k) g = 1.0 - math.min(1.0,m+k) b = 1.0 - math.min(1.0,y+k) and this is the one from Gimp (https://gitlab.gnome.org/GNOME/gimp/blob/master/libgimpcolor/gimpcolorspace.c) r = 1.0 - math.min(1.0,c*(1.0-k)+k) g = 1.0 - math.min(1.0,m*(1.0-k)+k) b = 1.0 - math.min(1.0,y*(1.0-k)+k) Wolfgang ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Hi,
\nabla should be italic if all other math greek symbols, like \Omega, \Gamma,
\sum, ect are set in italic. Otherwise \nabla and all such symbols should be
upright.
Would it be possible to make this optional in math italics, something like
\setupmathematics[mathsymbols=italic]
or
\setupmathematics[mathsymbols=upright]
Maybe this should be set when one chooses the greek letters to be italic or
upright in mathematics.
Best regards: OK

[NTG-context] NTG-context] How to hack the lua files
I haven't been using the project structure. From your question, I am inferring that this might help. At present I have treated the files as two separate documents. I didn't take too much time looking at how to set up the project structure because it wasn't clear that I needed it. But I can see how this might impact cross references between documents. -Lance On 6/17/2013 3:25 PM, Lance Larsen wrote: > Hans, > > Thankyou for your suggestion of using the \usereferences tag to reference > formulas in another document.
