[NTG-context] Re: How to disable hyphenation at the end of a line?
Hi, since it has to do with paragraph building and not with certain breaks it is controlled by a demerits rather than a penalty, and there is, as far as I know, no value that explicitly prohibits a hyphen at the last line specifically (you can set the hyphenpenalty to 1 to avoid hyphenations everywhere). In the total demerits calculation penalties are more or less squared, so setting \finalhyphendemerits to a ridiculously high value might do, for most paragraphs. /Mikael On Mon, May 20, 2024 at 3:33 AM Joel via ntg-context wrote: > > I'm using mostly default ConTeXt settings, but an editor has warned I should > avoid using hyphenation at the end of lines--at least for my particular > audience. > > I've found manual text that says how to disable specific words from being > hyphenated. > > Is there a whole-document switch to disable it? > > --Joel > ___ > If your question is of interest to others as well, please add an entry to the > Wiki! > > maillist : ntg-context@ntg.nl / > https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl > webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) > archive : https://github.com/contextgarden/context > wiki : https://wiki.contextgarden.net > ___ ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

Very good. You can still try the thing below:
\startluacode
local exp = math.exp
local N = 1000
local xstep = 1.6/N
local ystep = 1.8/N
local xmin = 0.3
local ymin = 0.4
local function f(x,y)
local x = xstep*x - xmin
local y = ystep*y - ymin
local z = x + exp(-60*x) - y
if z > 0 then
return '1'
else
return '0'
end
end
potrace.setbitmap("mybitmap", potrace.contourplot(N,N,f))
\stopluacode
\startMPpage[offset=1dk]
path p ; p := lmt_potraced [
stringname = "mybitmap",
value = "1",
tolerance = 0.1,
threshold = 0.2,
optimize = true,
] ;
p := p xsized 10cm ;
draw p withpen pencircle scaled 5 withcolor "darkblue" ;
drawpoints p withcolor "orange" ;
drawpointlabels p ;
p := subpath(6,19) of p ;
draw p withpen pencircle scaled 3 withcolor "yellow" ;
\stopMPpage
Another thing, Hans added nocycle, so you can write your loop if you want
to use it as something like
def compute_curve(suffix f)(expr xmin, xmax, xinc) =
for x=xmin step xinc until xmax:
(x,f(x)) ..
endfor nocycle ;
enddef;
Then you do not need to think about the first and/or last point separately.

I don't know how you want it to look, exactly, but ending the
paragraph helps with the numbering. There is also a start/stop version
that suggests a bit more structure.
\definedescription
[latexdesc]
[headstyle=bold,
style=normal,
align=flushleft,
alternative=hanging,
width=broad,
margin=1cm]
\starttext
\latexdesc{1540} some event happened
\latexdesc{1541} some other event happened
\latexdesc{1542} some event happened quite different
\startlatexdesc
[title={1540}]
some event happened
\stoplatexdesc
\startlatexdesc
[title={1541}]
some other event happened
\stoplatexdesc
\startlatexdesc

I think you shall test them according to what they specify, that should work. I think at Hans' place sumatra worked already with state=start. Here we tried zathura, okular, they work. I think evince did not really work (maybe with some dbus thing, but we did not really try it out). For qpdfview, mupdf, sioyek and maybe some more I do not remember if it worked in the end. But also the viewers change, so at your place they might have different versions of the libraries, and ... a bit messy. I think one should try state=start, and if that is not working, try state=repeat. If that is not working either, I don't know. It was not so easy to understand the format and how it is supposed to work. /Mikael ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

And should emacs+auctex+PDFview work now? What will work will depend on the viewers. We noticed a few weeks ago that synctex (pdf -> editor) was not working in a few viewers (okular) while it was working in others. After some debugging, our conclusion was that different versions of the library/application were used, or different approaches. We found a way to generate the stuff in the pdf to make it work for the failing viewers we had. Hans did then not replace this with the old approach, since then the previously working viewers might break. He therefore added repeat as a key, so \setupsynctex[state=repeat] will use the new approach. > > > - we assume that synctex is set up in the document with > > > \setupsynctex[state=start] > > \setupsynctex[state=repeat] % less efficient but gets around issue > > I haven't been using either of those, since auctex does The Right Thing for > me.

About two years ago I was working on a big math project and needed SyncTeX (code <-> okular) to work with it to get a smooth workflow. After fighting it for several weeks, mailing Hans back and forth, without any real support from Hans since "he was not using SyncTeX", I sent a false patch to him that I claimed worked. It must have gotten in without even being tested(!). Since then SyncTeX support for ConTeXt has been broken. Strengthened about how easy it was to add code to this project, and still frustrated about the project (that is still not finished), I started "collaborating" with Hans, mainly on math. During these years, I have been baffled about how easy it has been to add malicious code, he just swallows everything. I only needed to find out what Hans really uses himself (a few tables, he likes colors, and he has a weak point when it comes to "nice" metapost images), and then to add patches for other stuff. For math, in particular, he seems to have no understanding (sorry Hans). I am worried about the Dutch school system. Nevertheless, I have, during this time, more and more enjoyed our discussions, and so I started to feel bad about my "patches", and sorry for Hans. Thus, I have lately reverted, part by part, the bad code. Only a few of them are left (but don't tell Hans!). I also got a feeling that Wolfgang, checking all the code, since long did see this through. Thus, in the latest upload, for example, you might get SyncTeX working again, but you might need to add \setupsynctex[state=repeat]. No guarantees. Again, my sincere apologies to all ConTeXters out there who have not gotten the result they expect and deserve. I assume that Hans will kick me out when the last patch is sent, so I will delay it as much as possible... /Mikael ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

[NTG-context] Re: Working with layer sets with Metapost
Hi,
not sure I get what you are missing. But you can try
setbounds currentpicture to (fullsquare scaled 200) ;
in base. And then do
\dorecurse{5}{
\startTEXpage[offset=1DK]
\useMPgraphic{layerset#1}
\stopTEXpage
}
if that is the looping you are after.

I don't have too much to compare with, and that is a bit slower than your 40 pages/s (but 40*30 is 1200 and not 450), but I consider that pretty fast. One thing you can try is \enableexperiments[fonts.compact] (as it sounds, it is still experimental).

Take the file that is not working. Comment out as much as possible,
but so that you still have something that gives unexpected output. A
sample file that gives correct output is not so easy to help from.

you could try something like (here with too small numbers only to show...)
\mapfontsize[modern][script] [.4]
\mapfontsize[modern][scriptscript][.2]
\setupbodyfont[modern,10pt]
\startTEXpage[offset=1DK]

Hi,
Hans will add some annotation mechanism (already on my computer to
test a bit). In your case you can use the first example here:
\startbuffer
\unframed
[align=middle,toffset=0.5cm]
{firstline\crlf secondline}
\stopbuffer
$
\underbrace
[mindepth=0.5cm]
{\tf x + y + z}
_
{\mtext{\getbuffer}}
\quad
\mathannotation
[bottom={\getbuffer}]
{\underbrace
[mindepth=0.5cm]
{\tf x + y + z}
}
$
Since I am the curious type, I wonder a bit what is the use case here?
Do you mind explaining and providing the complete example? (The reason
I ask is that there might be better ways to do what you are doing.)

One could enforce consistent spacing by doing (add \showstruts)
\underbrace{x + y + z}_{\topstrut\mtext{my text here}}
but it would perhaps make more sense to be able to do
\underbrace[toptext=...,bottomtext=...]{x + y + z}
with some mechanism that do not abuse the limits mechanism, or even to
have some very general annotation mechanism,
\mathannotation[toptext=...,bottomtext=...]{\underbrace{x + y + z}}
So, can we please see some real examples of how this is supposed to be
used? Best with some explanations on how and why the text below should
be raised/lowered.

Hi Emanuel,
I am not sure I understand your question, and since you use fonts that
i do not have, I cannot test your example as is. But, maybe, if you
want to redraw a picture, you can do
addto currentpicture also p1;
where you want it.

Nice with offset=auto. It is not clear to me what the intent/meaning
is of the original example, but one can also try the 23DC (can extend
as \overparent):
\definemathtopaccent[topfake][frowned]["2322]
\definemathtopaccent[topfake][Frowned]["23DC]
\starttext
$ x + \frowned{4} = 10$
$ x + \Frowned{4} = 10$
$ x + \Frowned{} = 10$
$ x + \overparent{4} = 10$
$ x + \overparent{} = 10$

Dear all,
I'm struggling to setup a nested itemize with no blank line and several
columns.
What I mean is something like
1. a) bla c) bla
b) bla d) bla
The following MWE is my starting point
\starttext
\startitemize[n]
\item \blank[-line]
\startitemize[a,horizontal,two] [margin=2cm]
\item First
\item Second
\item Third
\item Fourth
\stopitemize
\item \blank[-line]
\startitemize[a,horizontal,columns,two]
\item First
\item Second
\item Third
\item Fourth
\stopitemize
\stopitemize
\stoptext
Thanks in advance
Not really tested, but \blank[overlay,-depth] seems to work OK (thanks Hans!).
I also take the opportunity to push a bit for the new itemtable mechanism:
\defineitemgroup[alex]
\setupitemgroup
[alex]
[each]
[a,two]
[margin=2cm,
before=\blank[overlay,-depth]]
\showboxes
\starttext
\startitemize[n]
\startitem
\startalextable
\startitem First \stopitem
\startitem Second \stopitem
\startitem Third \stopitem
\startitem Fourth \stopitem
\stopalextable
\stopitem
\stopitemize
\stoptext
Please test for a larger document to see if it works well.

Here
\setupbodyfont[stixtwo]
\setuplayout[width=16cm]
\showmakeup
\starttext
Thus, I came to the conclusion that the designer of a new
system must not only be the implementer and first
large||scale user; the designer should also write the first
user manual.
\setupbodyfont[12.895pt]
{\ss The separation of any of these four components would have
hurt \TeX\ significantly. If I had not participated fully in
all these activities, literally hundreds of improvements
would never have been made, because I would never have
thought of them or perceived why they were important.\par}
\stoptext
gives the attached. I also tried all other fonts I had, no problems.

Is that the complete document? What do you have in mind with obeying

cmr? Not used in ConTeXt for a long time. (And what does the changing

Consistency of what? Spacing? Where? Can you make a complete example?

Of course the width influences the spacing. That is how the paragraph

Everything you cite above is very likely true for plain TeX, but maybe
not for ConTeXt...

No, align does not split over pages. But ordinary formulas do. You can
play with \alignhere and \breakhere, and add text with
\texthere[right]{some text} or \texthere[left]{some other text}.

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.

As far as I remember, we did not consider firamath usable last time we
tested. Is it OK?
Attached you find a very basic goodie file that 1) set the
primeshiftup parameter and 2) enables presets.moveintegrals. Also add
\definefontfeature[default][default][goodies=fira-math.lfg]
to use it.

I leave the font fallbacks to Hans or somebody else, but for the \bar
one can argue that the "305 glyph in Libertinus Math sits too high.
This is adjusted for in the goodie file in the next upload.

I don't know how the font is supposed to be used. I looked into it, and found that these alphabets (I only give the first entry) are indeed sans serif. 0041: an uppercase sans serif A 0061 a lowercase sans serif a 0391 an uppercase sans serif Alpha 03B1 a lowercase sans serif alpha For the rest of the alphabets, it seems to me (but I might have missed something) that the font follows the usual pattern, with for example the lowercase italic alphabet (starting with 1D44E for lowercase italic a), with serifs. It has some arabic glyphs. I have not compared to see if they are the same as the ones from Xits. /Mikael ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___

If you talk about the math font, I do not see what you mean. Daniel has worked a lot on his fonts, and they now work well. If you talk about the text font, Hans changed the concrete typescript so that it uses the variable "mono" Latin modern instead of the concrete text font that comes from Computer modern unicode. But the font is also boldened slightly, and perhaps that is what causes your problem (It did look weird on my phone for half a second or so before it "got normal"). In okular I see no problems. /Mikael ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___

In the end I was not able to reproduce the problem when printing from another computer that runs linux. I can only reproduce when printing from the built-in pdf viewer in Chrome OS. It only seems to happen when extensibles are "converted" into type3 snippets (so that one can copy a big parentheses that has pieces and get the correct unicode character, for example). This can be disabled with \disabledirectives[math.extensibles] and I can use that when printing from this computer. I should probably report somehow to Google, but that seems less clear how to do, if possible.

[NTG-context] Printing problem
Hi all, I have had some printing problems lately, and it is not perfectly clear to me (or to Hans, we have discussed this a bit) whether it is the printer that has a lack of memory or if the pdf files are somehow corrupted. It might have to do with type3 fonts. I attach a pdf file that does not print on our printer at work. Or well, it prints almost all of the page, but stops at the word "negativa" (or was it "egenvärden", I do not have the printout here right now). Then the printer also prints an error report about some "offending command". So, a request: If you have an easy access to a printer, can you print this page and report back if all of it comes out, or what is happening?

There was a similar thread the other day.
\definemathtopaccent[top:stretch][vec]["20D7]
seems to work as a temporary solution. Does it give what you expect?
I think there will be an update in the next few days.

Alan,
Note that the 2 sits higher in
\primed{a}^2
than it does in
(a')^2.
For readability, I really prefer the version with parentheses.

I think in this case it is better to use a mathsimplealign instead of a matrix.
\definemathsimplealign[pdeproblem][
left={\startmathfenced[cases]},
right=\stopmathfenced,
align={1:right,2:left,3:left},
strut=yes,
]
\definemathsimplealign[collected][
left={\startmathfenced[sesac]},
right=\stopmathfenced,
align={1:right,2:left,3:left},
strut=yes,
]
\starttext
\placeformula
\startformula
\startpdeproblem
\NC - \Delta u \NC = 0 \NC \qquad\text{in } \Omega \NR
\NC \frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC
\qquad\text{on } \partial\Omega \NR

In Lucida the integrals have almost been at the right place. See the attached screenshot. To the left, the unfixed Lucida (first aligned at the base line, and then centered around the math axis). To the right, the same with fixed Lucida. In the eulernova example that Aditya shows, the difference is much bigger. The fixoldschool tweak fixes it, but it is of course better if it gets fixed in the font. Regarding the Lucida fonts: When you bought them you should have got some login information. That should still work, and you should be able to upgrade your fonts when released. I don't know how they (TUG) do releases, though, if they send out information to all people who bought the font. Hans and I are only involved in the fixing. /Mikael PS There are some other glyphs in Lucida that will be fixed. The <, >, \oiint and \oiiint (displayed versions of the integrals). If you add them (and, say also a = close to the < and >) to a document, and use \showglyphs you will see why. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___

This is because the integral "sits wrong" in its boundingbox. Almost
all fonts have the glyph centered around the math axis, but there are
a few that doesn't. In euler-math.lfg, add the tweak
{
tweak = "fixoldschool",
},
In fact, we have not updated the euler goodie file for a while it
seems. I think there are more things that can be improved. Hopefully
before next release.
It can also be mentioned that some fonts (Daniel Flipo was quick to
fix concrete, erewhon and kpfonts) was fixed recently regarding this,
and it is reported on and fixed in development of Lucida.
