[NTG-context] Bug? Text following columns at end of page goes into footer not next page

[Bruce Horrocks]

Two column text that ends near the foot of a page can push the next line into 
the footer rather than starting a new page.

MWE for ConTeXt  ver: 2023.09.26 18:19 LMTX :-

\setuppapersize [A4]

\starttext
Knuth in knolumns

[NTG-context] Bug(?) in https://wiki.contextgarden.net/Tabulate#Spanning_Multiple_Pages

[Jim]

Hi,

In https://wiki.contextgarden.net/Tabulate#Spanning_Multiple_Pages the wiki
has "internal error: convert failed".

Removing \color[red] from \setuptabulate in that example gives a working
example (at least in a separate file on my machine).  I tried changing the
title specification to
title={\color[red]{Fenchurch St. Paul}},
as well as
title={{\color[red]{Fenchurch St. Paul}}},
but both of these reward me with a runaway context process.

Can someone point out the correct way to do what the wiki intended?

Thanks.
Jim

P.S. Bonus question: should an incorrect use of color really cause an
(apparent) infinite loop, or is that a second issue which deserves to be on
some to-do list?

[NTG-context] Bug or feature? \numexpression and hashes

Hi, list. The following fails with a "Missing number, treated as zero"
error prompt:

\starttext

OTOH, \numexpr works seamlessly. Tested on ConTeXt 2023.09.03 19:03. Thanks
in advance.

Best regards,

sure, as it makes no sense to write ansi sequences to the log so then 
that channel is turned off

Where can i find that font? There was a time when one could download a
zip with all noto fonts but last time i checked that option was gone
and
one ends up with downloading single ones which is a waste of time but I
might have missed a link.


These fonts that I use are provided in ubuntu desktop. If you have an 
ubuntu system, you can get all of them by


$ sudo apt install fonts-noto-cjk # or more fonts in the 
fonts-noto-cjk-extra package.


The package includes the following fonts:

NotoSerifCJK-Regular.ttc
NotoSerifCJK-Bold.ttc
NotoSansCJK-Bold.ttc
NotoSansCJK-Regular.ttc

I have  uploaded the four of them into github. The download link is

http://liyanrui.github.io/share/fonts/fonts-noto-cjk.zip 


Ok. I'll check it.

Re: [NTG-context] Bug with \startnarrow?

[peter.hopcroft--- via ntg-context]

It's the documentation that has the bug. With \startnarrow, you need two sets 
of square brackets, 1 for the \setupnarrower data and 1 for the \startnarrower 
data. Like this:

\starttext
Some text before
\startnarrow[left=5cm,right=1cm,before={\blank[2*line]},after={\blank[halfline]}][left,
 right]
narrower text
\stopnarrow
some text after
\stoptext

[NTG-context] Bug with \startnarrow?

[Denis Maier via ntg-context]

Hi,

While doing some more tests with my example from yesterday (tables in 
\startnarrow), I've realized that the example from the wiki doesn't seem to 
quite work as expected:

%%
\starttext
Some text before
\startnarrow[left=2cm,right=1cm,before={\blank[2*line]},after={\blank[halfline]}]
narrower text
\stopnarrow
some text after
\stoptext
%%

Already here, the extra margins on both sides seem to be equal. Changing the 
size of the left extra margin has no effect at all.

%%
\starttext
\startnarrow[left=10cm,right=2cm]
\input ward
\stopnarrow

but:

\setupnarrower[left=5cm, right=2cm]
\startnarrower[left,right]
\input ward
\stopnarrower
\stoptext
%%

Is this a bug or intended behaviour ?

Best,
Denis

Hugo,

I have just updated the wiki with another way of line breaking SHA sums:

  https://wiki.contextgarden.net/Wrapping#Line_breaking_with_SHA512_sums

It avoids the issue you encountered and it is an easy workaround.

Just in case it might help,

Pablo

Line breaks are removing characters.

Many thanks for your report, Hugo.

I use this code from time to time and I totally overlooked this.

Hans,

I have just checked that these line breakings loose a character in all
options.

The next sample displays the issue clearly:


   \startluacode

 --local shared = {

 --left   = false,

local shared = {

-- languages.hyphenators.traditional.installmethod("sha",
-- function(dictionary,word,n)
-- local t = { }
-- for i=1,#word do
-- t[i] = shared
-- end
-- return t
-- end
-- )

-- or more efficient when used often:

-- local all = { }
-- for i=1,512 do
-- all[i] = shared
-- end
-- languages.hyphenators.traditional.installmethod("sha",
-- function(dictionary,word,n)
-- return all
-- end
-- )

-- or more obscure:

-- local all = table.setmetatableindex({ }, function(t,k)
-- t[k] = shared
-- return shared
-- end)
--
-- languages.hyphenators.traditional.installmethod("sha",
-- function(dictionary,word,n)
-- return all
-- end

-- or just (lua is fast enough anyway)

[NTG-context] Bug in verbatim wrapping examples on wiki

[Hugo Landau via ntg-context]

On this page of the wiki there is an example for wrapping long words,
like long hexadecimal strings:

https://wiki.contextgarden.net/Wrapping

This example is buggy because it deletes one character at the point that
it is wrapped.

In the example given, running context turns '257a410' into '257410'.

The DNA example below it exhibits the same problem.

Anyone have a solution?

Re: [NTG-context] bug $\vec{}$

Not sure if this is related in any way, but \overset behaves weirdly with the 
equal sign:

\startformula
\overset{weird}{=}
\stopformula

(workaround/solution is \overset{weird}{\mathop{=}}, or \mathop{=}^{weird})

I confirm the behavior.

Also possibly linked is that the spacing around $\overrightarrow{k}$ seems
pretty weird, so atm there is no fallback solution.

Hi Mikael,

Thanks for your reply.
Indeed with your hint the issue disappears.

Re: [NTG-context] Bug in math alignment

Dear Jeong,

Thanks for testing my example, and pointing to the solution using \dm (which I 
didn’t know…).
I think the correct behaviour of math alignments should avoid using additional 
commands such as \dm.

We’ll see what Hans and Mikael say.

Dear Otared,

I confirm what you said.

However, if I use \dm{} instead of \displaystyle as following, then the output 
is correct.

\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \dm{\frac{\partial u}{\partial {\bi n}}}
 \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
or this (with\type{\displaystyle} added)
\placeformula 
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \dm{\frac{\partial u}{\partial {\bi n}}}
 \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula

In this example, it is OK to use \dm inside of \startformula … \stopformula.
I am not sure that it is what Hans and Mikael want.

Thanks,

Best regards,

Dalyoung

[NTG-context] Bug in math alignment

[Otared Kavian via ntg-context]

Hi Hans and Mikael,

I think there is an issue with the size of math fonts in \frac when used in 
math alignments, as it is is shown in the following example.


%% begin bug-mathalignment.tex
\definemathmatrix[alignedcases]
[align={1:right,2:left,3:left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]

\starttext
Consider this
\placeformula
\startformula
\startalignedcases
\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
\stopalignedcases
\stopformula
or this (with\type{\displaystyle} added)
\placeformula 
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \displaystyle\frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC 
\qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
Actually, one should have this
\startformula
\frac{\partial u}{\partial {\bi n}}  = V u + \phi  \qquad\text{on }\, 
\partial\Omega.
\stopformula
If one adds \type{\displaystyle} both to the numerator and denominator of 
\type{\frac}, the result is correct:
\placeformula 
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \frac{\displaystyle\partial u}{\displaystyle\partial {\bi n}} \NC = V u + 
\phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula

\stoptext

[NTG-context] Bug in startalign

[Stefan Haller via ntg-context]

Hi!

I (presumably) found a bug in the recent math changes of the latest
upload. If a cell of the startalign environment is empty, something
internally to the macro seems to be breaking.

Minimal example:

\starttext

\startformula
  \startalign
\NC   \NC a \NR
\NC b \NC c \NR
  \stopalign
\stopformula

\stoptext

Error: 
> tex error > tex error on line 5 in file ./test.tex: Missing number, treated 
> as zero
> 
> \23C>1
> 
> \math_next_in_eqalign \math_left_of_eqalign \mathbeginclass \csname 
> \??mathendclass \the \numexpr \c_math_eqalign_column -\plusone \relax 
> \endcsname
> \startforceddisplaymath \everycr \emptytoks
> 
> a
> 

Filling the empty cell with e.g. "d" makes it work. Using "\strut" or
"\quad" or similar also leads to the same error.

Best regards,
Stefan Haller

Thanks for reporting! We must have missed this one while testing. It
should be fixed.

If you for the moment can live without splitting, then this seems to
give you the formula number where expected:

\placeformula
\startformula[location=left,split=no,numberlocation=overlay]
a^2 + b^2 = c^2.
\stopformula

(or put the keys in \setupformula)

I hope it helps.

[NTG-context] Bug in placeformula

[Otared Kavian via ntg-context]

Dear Hans, dear Mikael,

In my experiments with the new math engine, I noticed that there is an issue 
with \placeformula when one sets the location of the numbers on the left: the 
number is one line above the formula. Here is a minimal example:

% begin bug-placeformula-left.tex
\setupformulas[location=left]

\starttext

\placeformula
\startformula
a^2 + b^2 = c^2.
\stopformula

\stoptext
% end bug-placeformula-left.tex

Moreover, in some environments (such as enumerations) the bug destroys 
completely the flow of text but I could not set up a minimal example to send 
you.

Best regards: Otared

[NTG-context] [Bug] Two-column text: Larger top spacing in inline images

[Marcin Ciura via ntg-context]

Dear Hans and ConTeXt developers,

When you compile the following code with ConTeXt ver: 2021.10.28 10:19, you
will see that:
* in 1-column text the top spacing of the circle is normal,
* in 2-column text, the top spacing of the circle is too large.
Here is the link to the output PDF:
https://live.contextgarden.net/cgi-bin/result.cgi?id=7K5tLW

Re: [NTG-context] Bug in alignment with LMTX version 2022.01.15 17:32

[Otared Kavian via ntg-context]

Hi Hans and Aditya,

Thanks for the clarification. Since for some documents I still use mkiv, I 
ended up using a definition which depends on whether one is using mkiv or lmtx, 
as in the example below. I wonder if there is a better solution.

Not a bug, but new interface. You need:

\definemathmatrix[matrix]
  [align={1:right,2:left,3:left}]

It is also possible to say: align={all:middle}. Combination of the two don't 
seem to work.
basically we increment each element but a number sets the column so one

I confirm that this is a bug, which was not there in the version from mid Dec. 
It appears that the align key does not have any effect. Here's a simpler 
example:

\definemathmatrix[matrix]
[align={right,left,left}]
\starttext

\startformula
  \startmatrix
 \NC ABC\NC ABC\NC ABC\NR
 \NC AA \NC AA \NC AA \NR

[NTG-context] Bug in mp-xbox.mpxl (circleit)

[Jacob Kauffmann via ntg-context]

Hi list,

I realized that circleit throws an error.
It works fine if I replace boxes_generic_declare by boxes_declare in line 244 
in mp-xbox.mpxl

rboxit is probably affected as well, but I did not test that.

MWE:
\startMPinclusions
input boxes;
\stopMPinclusions

\startMPpage
circleit.a(textext("$X$"));
drawboxed(a);
\startMPpage

The error (truncated) message:

method 'default'

Hi,

There is a bug in lmt_arrow. If given a "non-cycle" path, lmt_arrow
completes the cycle.

  \starttext

p := origin .. (1cm, 1cm) .. (2cm, 0);

With 2021.11.11, I get the attached file. Note that lmt_arrow has drawn the
"cycle" version of the path, even though p does not have a cycle.

I have looked at the code and cannot figure out why this is happening.


it happens in the 'direct' variant (metapost.registerdirect) where a boolean
is passed as signal and that boolean then is also picked up by the (shared)
path injector as (old school) signal that a path is closed while it should
instead consutl the closed field in a path table (sounds more complex than it
is)

so in the end it is a nasty side effect of the fast inject code path (shared
function with different stack values; i'll probably have to ditch a "low level
backward compatibility feature no one uses anyway" some day)

i uploaded a fix that you can test when the bins are compiled at

https://build.contextgarden.net/#/waterfall?tags=c.luametatex

new bins then in:

https://dl.contextgarden.net/build/luametatex/

(fyi: in the mp code you see that the path p is 'get' from the lua end where
it got passed to by parameter)


Thanks! Works perfectly here.

I was reusing two year old code and took me a while to figure out why the 
output was suddenly wrong.

There is a bug in lmt_arrow. If given a "non-cycle" path, lmt_arrow completes

With 2021.11.11, I get the attached file. Note that lmt_arrow has drawn the

I have looked at the code and cannot figure out why this is happening.


it happens in the 'direct' variant (metapost.registerdirect) where a 
boolean is passed as signal and that boolean then is also picked up by 
the (shared) path injector as (old school) signal that a path is closed 
while it should instead consutl the closed field in a path table (sounds 
more complex than it is)


so in the end it is a nasty side effect of the fast inject code path 
(shared function with different stack values; i'll probably have to 
ditch a "low level backward compatibility feature no one uses anyway" 
some day)


i uploaded a fix that you can test when the bins are compiled at

https://build.contextgarden.net/#/waterfall?tags=c.luametatex

new bins then in:

https://dl.contextgarden.net/build/luametatex/

(fyi: in the mp code you see that the path p is 'get' from the lua end 
where it got passed to by parameter)


(interesting that it didn't show up sooner, maybe most users have closed 
paths and/or most lmt_ features used closed paths)

[NTG-context] Bug in lmt_arrow

[Aditya Mahajan via ntg-context]

Hi,

There is a bug in lmt_arrow. If given a "non-cycle" path, lmt_arrow completes 
the cycle. 

\starttext

\startMPcode
  newpath p;
  ahfactor := 5;
  p := origin .. (1cm, 1cm) .. (2cm, 0);
  draw lmt_arrow
   [
 path = p, 
 location = "percentage",
 percentage = 50,
 alternative = "curved", 
   ]
   withpen pencircle scaled 1bp;
\stopMPcode
\stoptext

With 2021.11.11, I get the attached file. Note that lmt_arrow has drawn the 
"cycle" version of the path, even though p does not have a cycle.

I have looked at the code and cannot figure out why this is happening.

Thanks,
Aditya

[NTG-context] Bug with mathalignment and columns

[Jack Hill via ntg-context]

Hi,

When a mathalignment is started at the end of a multi-column page ConTeXt 
places it at the start of the previous second column instead of placing it on a 
new page. Here's my code to test:

\starttext \startcolumns[n=4]
\startluacode
lorum = "Lorum ipsum dolor sit amet. "
for i = 1, 98, 1 do
context(lorum)
end
\stopluacode

\startformula \startmathalignment[n=1]
\NC y = ax \NR

\NC a^2 + b^2 = c^2 \NR

\NC x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \NR
\stopmathalignment \stopformula
\stopcolumns \stoptext

Adding text after the formula seems to fix the issue, but that means I can't 
finish the page with a formula.
It seems that it always places the formula at the top of the second column, 
regardless of how many columns there are.
It also does this even if there are still empty columns (try changing 98 to 100 
in the for loop).

You're right, I just checked the symbols of luatex and they contain all the

So I guess the problem is specific to luametatex and the latest context.

Does luatex have dedicated headers different from the ones for stock lua?

I don't know lpeglabel, but luatex has the lpeg embedded and perhaps it can
clash with the library.

[NTG-context] Bug: missing Lua API in binaries

[Sylvain Hubert]

Dear Devs,

Sorry if this is not the best place for reporting bugs.

I'm trying to use the lpeglabel library written in C and delivered as
lpeglabel.so.

$ ls
testlabel.lua lpeglabel.so
$ cat testlabel.lua
require("lpeglabel")

The ConTeXt binary cannot load the library because it lacks certain Lua API:

$ context --forcecld --permitloadlib testlabel.lua
...
fatal lua error:
registered function call [1542]:
...tx/tex/texmf-context/tex/context/base/mkiv/l-package.lua:348: error
loading module 'lpeglabel' from file './lpeglabel.so':
./lpeglabel.so: undefined symbol: lua_gettop
...

nor does LuaTeX:
$ luatex -luaonly testlabel.lua
error loading module 'lpeglabel' from file './lpeglabel.so':
./lpeglabel.so: undefined symbol: lua_getiuservalue

It seems that lua_gettop and others are optimized out from the `context`
binary, while lua_getiuservalue and others are missing from `luatex`.

I'm not sure if it works but I would suggest adding `__attribute__
((used))` to the `LUA_API` macro if the binaries are compiled with gcc.

Best,
Sylvain

This is likely the side effect of new implementation of glues in LMTX,

Many thanks for your reply, Wolfgang.

So, I didn’t make any sense in my sample.

You need \determineheadnumber[section] before you can use

You can use \headnumbercontent only when you create a new section layout

   \headnumber[section]


It's a bug.

In LMTX, \headnumber[section] triggers an error message about missing

BTW, \currentheadnumber outputs 0 in both MkIV and LMTX. I think this
may be a bug.

Could anyone confirm both issues?

Forgot to mention that my program is LuaTeX 2.08 20210220 + ConTeXt MkIV

Also I like \setupbacked for what it does (export html/xml/css), I just

pdf.

[NTG-context] Bug in generating the highlight colour in the rules-mkiv document

[Ivan Čukić]

Hi all,

When compiling the rules-mkiv.tex (context/sources/general/manuals/rules)
file, the highlight lines that use mp graphics are rendered in black instead of 
the colour defined by the file. This is visible on the three test sentences on 
the top of the third page "test test me and test or grep".

The versions I've tested where this is broken are:

context from the current TexLive 2020 distribution
mtx-context | ConTeXt Process Management 1.03
mtx-context |
mtx-context | main context file: texmf-dist/tex/context/base/mkiv/
context.mkiv
mtx-context | current version: 2020.03.10 14:44
mtx-context | main context file: texmf-dist/tex/context/base/mkiv/
context.mkxl
mtx-context | current version: 2020.03.10 14:44

context installed via first-setup.sh
mtx-context | ConTeXt Process Management 1.03
mtx-context |
mtx-context | main context file: tex/texmf-context/tex/context/base/mkiv/
context.mkiv
mtx-context | current version: 2020.01.30 14:13
mtx-context | main context file: tex/texmf-context/tex/context/base/mkiv/
context.mkxl
mtx-context | current version: 2020.01.30 14:13

context from TexLive 2019 distribution
mtx-context | ConTeXt Process Management 1.02
mtx-context |
mtx-context | main context file: texmf-dist/tex/context/base/mkiv/
context.mkiv
mtx-context | current version: 2019.03.21 21:39


The latest version I found to be working:

context installed with TexLive 2018
mtx-context | ConTeXt Process Management 1.02
mtx-context |
mtx-context | main context file: texmf-dist/tex/context/base/mkiv/
context.mkiv
mtx-context | current version: 2018.04.04 00:51


Cheers,
Ivan

This is normal, to load figures from the tex directory use

works with a local image (say, if "cow" is in the same folder as the main
file), but it doesn't find sample images (cow, hacker, etc.). Is that a bug
or an intended result? Thank you in advance.

Best regards,

Jairo

[NTG-context] Bug in lmtx bibliography (numerals in entry?)

[Damien Thiriet]

Hello,


My bibliography files compiles fine in mkiv, but hangs in lmtx
Here is the error message:

tex error   > tex error on line 30 in file ./Nation_rev_empire.mkiv:

If you say, e.g., '\def\a1{...}', then you must always put '1' after
'\a',
since control sequence names are made up of letters only. The macro here
has not
been followed by the required stuff, so I'm ignoring it.

I am using a custom biblio style, but the command \btxshowentryinline is
not directly called inside.
My ConTeXt version
mtx-context | ConTeXt Process Management 1.04
mtx-context |
mtx-context | main context file:
/usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context | current version: 2020.11.19 11:28
mtx-context | main context file:
/usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkxl
mtx-context | current version: 2020.11.19 11:28



AFAIU, it  means my entry shouldn’t have numbers, right? If so, this may
be a bug, since entry biblio files often have a number inside

Best regards,

Damien Thiriet

I forgot the \tolerant prefix in:

Sorry for the delay, I had to downsample the screenshots after the original
reply didn't get through (too big) and in the end remove them completely.

Thank you for checking. Looks like a bug in Acrobat (older version
11.0.23), not ConTeXt.
What editors do you use?

After your test I was digging deeper. When I disable black plate in *Preview:
Separations* it doesn't show an overprint, the room under the letters is
white (original problem). When I remove one overprint manually in
Illustrator, Acrobat shows the remaining overprints. I've found out later,
I could use *Profile: Color Warnings*, where all overprints are visible,
but I would rather see it in separated plates.

Hope this helps someone in the future, too.
Jano

Re: [NTG-context] Bug in matrices/alignment (LMTX)

[Jairo A. del Rio]

Nice. When I add empty braces ((}) the example works. Just curious: is that
a bug or expected behaviour?
Thank you a lot, Wolfgang.

Cordially,

Jairo :)
