Re: [NTG-context] fallbacks

[Sylvain Hubert via ntg-context]

I believe it's a bug.

https://github.com/contextgarden/context/blob/d025bcdf995be6951f69fed6869048ab22491b9e/tex/context/base/mkxl/font-col.lmt#L278

the newchar[] table, which should contain all chars supported by the
fallback termes font if I'm not mistaken, turns out to have only 392 chars
within 0x20-0x30C, far away from 0x2329-0x232A.

Re: [NTG-context] horizontal space in CJK document

[Sylvain Hubert via ntg-context]

Thanks, but I guess the space width would be fixed.

I just found a hack: 口口\hspace[big]\hbox{}口口 does the trick.

It's a gain exactly because it's not another information source. The posts
are synced. It's just a modern and imo better UI for the mailing list, with
more pleasant searching and tracking UX.

Thanks, Pablo and Bruce. Both solutions work well.

> I had similar issues with \section and only the Latin script was involved.

Btw, just in case if anyone shares this idea: is it possible to have a
zulip channel for ConTeXt? It's free for open source projects, has a
interface for existing mailing lists, and has a reasonable builtin search
engine, which could serve as another de-facto documentation, considering
the fact that very few of the massive useful use cases asked in the mailing
lists so far have been transcribed into official documentations.

[NTG-context] How to prevent \subject from being the last line

[Sylvain Hubert via ntg-context]

Dear list,

I have a long document (A4 * 170 pages) with some CJK fonts, where some of
the \subject{...} are placed at the end of the corresponding pages, which
looks awkward. How can one flush those last-line titles to the next pages?

Currently I don't have a MWE, as trivial filling-up with 1-2 pages of
\lipsum doesn't reproduce the problem. I'm optimistically asking without
MWE, but if it is necessary anyway, please tell me and I will obfuscate the
170-page document and find a way to upload it.

Many thanks,
Sylvain

In the table of contents, s1 and s2 (at page 1) are rendered in red, while
others in green.

Moreover, when I click s4, it jumps to page 2 without locating the section
precisely within the page.
This is not the case when using the latex hyperref package.

Does anyone know how to make the colors uniform and the links precise?

[NTG-context] Roman PDF labels

[NTG-context] Equation alignment

The following example of equation alignment copied from An Excursion

\starttext
\startformula
\eqalign{
ax^2+bx+c &= 0 \cr
x &= \frac{-b \pm \sqrt{b^2-4ac}}{2a} \cr

Both ampersands are rendered literally.

Does anyone know how to properly typeset aligned equations?

[NTG-context] features of fallback font

[Sylvain Hubert via ntg-context]

Dear List,

I'm using the chinese simsun font that has no builtin SerifBold.

I'm trying to define a fakebold feature for it, but the following code
does not work:

\definefontfeature[fakebold][effect={width=0.3, delta=0}]

\definefontfallback [sunfallback] [name:simsun] [cjkunifiedideographs]
\definefontfallback [sunbffallback] [name:simsun]
[cjkunifiedideographs][features=fakebold]

\definefontsynonym [Serif] [modern] [fallbacks=sunfallback]
\definefontsynonym [SerifBold] [modern] [fallbacks=sunbffallback]

\starttext
人 foo \bf 人 bar  % bar is bold, the second 人 is not
\stoptext

Does anyone know how to define features for fallback font?

Thanks!

Best,
Sylvain

Re: [NTG-context] margin of inner item group

[Sylvain Hubert via ntg-context]

Thanks but I believe 'distance' means ' * <--> text',
while margin means '<--> * text'.

[NTG-context] margin of inner item group

[Sylvain Hubert via ntg-context]

Dear List,

Does anyone know how to set the margin of an inner item group? The
natural way does not seem to work:

\showframe
\starttext
\startitemize[margin=5em]
\item 1
\startitemize[margin=10em]
\item 1
\item 2
\item 3
\stopitemize
\item 2
\item 3
\stopitemize
\stoptext

In the doc above, only the outer item group has a margin.

Any help will be appreciated.

Best,
Sylvain

Re: [NTG-context] itemize problems

[Sylvain Hubert via ntg-context]

A few more information:

For the 1st problem:

It seems that \setupitemize accepts two option groups, to which
n,packed and margin belong accordingly. However,
\setupitemize[n][margin=2em] does not seem to work.

For the 2nd problem:

\setupitemize[columns,one], although doing nothing in theory, seems to
fix the problem.

For the 4th problem:

I've found that we can do \setupitemize[A,text] which makes it like

(A.) 0 (B.) 1 (C.) 2 (D.) 3

The problem now is, how can we remove the parentheses around the item labels?

[NTG-context] itemize problems

[Sylvain Hubert via ntg-context]

Dear List,

Here's a collection of four problems about item groups that I've just
encountered.

1. 'n' and 'packed' not playing well with other options.

This works:

\defineitemgroup[myitems][itemize][margin=2em,before=before]
\setupmyitems[n,packed]

\starttext
text
\startmyitems
\item 1
\item 2
\stopmyitems
\stoptext

This does not:

\defineitemgroup[myitems][itemize][margin=2em,before=before,n,packed]

This does not either:

\defineitemgroup[myitems][itemize]
\setupmyitems[n,packed,margin=2em,before=before]

Is there a rule for this glitch which makes it worth memorizing, or is
this just a bug?

2. 'before' not working in nested item groups.

\starttext
\startitemize[before=before1]
\item 1
\startitemize[before=before2]
\item 2
\stopitemize
\stopitemize
\stoptext

Both before1 and before2 should appear, but only before1 is shown.

3. How to wrap the line under the bulletin or number?

To be more precise, the current wrapping behavior of, say, "\item 0 1
2 3 4 5 6 7 8 9" is:

* 0 1 2 3 4 5 6 7
  8 9

How can we remove the indentation of the second line and make it like

* 0 1 2 3 4 5 6 7
8 9

4. How to put the items on the same line?

That is, for "\item 0 \item 1 \item 2", I would like it to be like

* 0   * 1   * 2

instead of

* 0
* 1
* 2

My context version: 2021.03.05 19:11, texlive.

Any help with any of the problems above would be greatly appreciated.

Best,
Sylvain

[NTG-context] \usemodule[chinese] not found

[Sylvain Hubert via ntg-context]

Dear List,

I'm trying to typeset an item group (itemize) with chinese numbering. It is
suggested in multiple older documentations and answers that
\startitemize[c] should be used, for which \usemodule[chinese] is required.

But I can no longer find the 'chinese' module neither in texlive, in lmtx,
nor on the website. Has this module been removed or replaced by something
else?

Thanks!

Best,
Sylvain

[NTG-context] Automatically adjust number of table columns

[Sylvain Hubert via ntg-context]

Dear List,

I'm trying to make "\startchoice", "\stopchoice", and "\choice", such that:

\startchoice
\choice -1
\choice 0
\choice 1
\choice N/A
\stopchoice

results in (_ for whitespace)

A. -1__B. 0__C. 1__D. N/A

while

\startchoice
\choice not so short choice
\choice must wrap here
\choice another choice
\choice yet another choice
\stopchoice

results in

A. not so short choiceB. must wrap here
C. another choice___D. yet another choice

In another word, it should have the same effect as the addData() function
in the page below (save as whatever.html and open it)




table { width: 100%; border: 1px solid black; }
#root { width: 10cm; }








function make(tag, children) {
const node = document.createElement(tag);
for (const c of children) {
if (typeof c === "string") {
node.appendChild(document.createTextNode(c));
} else {
node.appendChild(c);
}
}
return node;
}

function addData(data) {
const root = document.getElementById("root");

let table = make("table", [make("tr", data.map(d => make("td", [d])))]);
root.appendChild(table);
if (table.scrollWidth <= root.offsetWidth) {
return;
}

root.removeChild(table);
table = make("table", [
make("tr", [make("td", [data[0]]), make("td", [data[1]])]),
make("tr", [make("td", [data[2]]), make("td", [data[3]])]),
]);
root.appendChild(table);
if (table.scrollWidth <= root.offsetWidth) {
return;
}

root.removeChild(table);
table = make("table", data.map(d => make("tr", [make("td", [d])])));
root.appendChild(table);
}

addData(["1".repeat(10), "2".repeat(10), "3".repeat(10), "4".repeat(10), ]);
addData(["1".repeat(20), "2".repeat(20), "3".repeat(20), "4".repeat(20), ]);
addData(["1".repeat(30), "2".repeat(30), "3".repeat(30), "4".repeat(30), ]);




Does anyone have an idea how it can be implemented in context?

Thanks in advance!

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

[Sylvain Hubert]

You're right, I just checked the symbols of luatex and they contain all the
APIs of lua 5.3.
So I guess the problem is specific to luametatex and the latest context.

> but in any case you should compile against the luatex headers, not the
stock lua 5.3.6.

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

[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

[NTG-context] context() does not ignore space in empty line

[Sylvain Hubert]

Dear list,

does anyone have an idea why, in the example below, context() starts a new
paragraph at "\n\n" but not at "\n \n" with a space in between? Is there
any way to fix it?

\starttext
Without using context(), inside the next parentheses is a new line: (

) note that a space sits between the two line breaks.

\startluacode
  context('Using context(), inside the next parentheses is also a new line:
(\n\n) because there is *no* space between the two line breaks.\n\n')
  context('Using context(), inside the next parentheses is however *no* new
line: (\n \n) because of the space between the two line breaks.\n\n')
\stopluacode
\stoptext

Any help is appreciated.

Best,
Sylvain

You could probably put the notes inside a \start...\stopxtablefoot

Indeed. Thanks for the information!

For the record, this is how the problem is finally solved:

\setuphead[section][after={\blank[sampage]}]
\begingroup\setupindenting[no]\dontleavehmode\startxtable …

Weirdly enough, "\hskip 0pt" solves the problem.

\setuphead[section][after={\blank[samepage]\hskip 0pt}]

\showframe
\dorecurse{50}{a }
\startsection[title=spec]
\startxtable
\startxrow
\startxcell[ny=30]a\stopxcell\startxcell 1\stopxcell
\stopxrow
\dorecurse{29}{\startxrow\startxcell 2\stopxcell\stopxrow}

Hi Wolfgang,

Thanks for the suggestion, but as illustrated by the second example, copied
here, where the section title is at the top of the page:

\starttext
\showframe
\dorecurse{50}{a }

Hi Pablo,

Thanks for the suggestion, but unlike the MWE, in the original document,
the table has ten rows and is visually not suitable for a split. The large
row span is meant to represent this restriction.

Hello Pablo,

Thank you very much for the help. The penalty of \blank indeed brings the
solution closer and it does format the previous example correctly.

However, when I went back to the original document, neither
[before={\blank[preference, big]}] nor [after={\blank[samepage, big]}] nor
both worked. I trimmed it into the following example which behaves the same:

\starttext
\showframe
\dorecurse{50}{a }
\startsection[title=spec][before={\blank[preference,big]},
after={\blank[samepage,big]}]
\startxtable
\startxrow
\startxcell[ny=30]a\stopxcell\startxcell 1\stopxcell
\stopxrow
\dorecurse{29}{\startxrow\startxcell 2\stopxcell\stopxrow}
\stopxtable
\stoptext

Do you have an idea on how this could also be formatted correctly or how
one could inspect and debug the penalty?

Thanks again!

Hi Jairo,

Thank you very much for the suggestion and the thorough explanation.

I extracted the metapost code to a new file because I felt it would be a
bit lengthy and noisy to stay with the text content.

But you're right, an extra compilation step is not any better. I should
probably use \component figure.tex, in place of \externalfigure[figure.1]

[NTG-context] embed metapost figure into document

[Sylvain Hubert]

Dear List,

I'm trying to embed a metapost image into the document. According the MetaFun
manual ,
"embedding such a graphic is done by:
\externalfigure[graphic.123][width=4cm]", but the following example
produces an empty page:

% test.mkxl
\starttext
\externalfigure[test.123][width=4cm]
\stoptext

% test.123
draw fullcircle scaled cm withcolor black;

Does anyone know how to properly embed a metapost image into a context
document?

Thanks!

It seems that the buffer mechanism is quite a powerful resort for the macro

[NTG-context] \type{...} as macro argument

Dear List,

I would like to ask how to define a command, \same, such that

\same{\type{a   b c}}

produces the same result as its argument does

\type{a   b c}

The naive way doesn't work because it makes all the spaces collapse:

\define[1]\same{#1}

I would also like to ask whether this could be achieved using the lua
interface:

\startluacode
interfaces.definecommand {
   name="same",
   -- catcode/mode/arguments = ???
}

So \switchtobodyfont before \starttext is semantically an error then.

Thank you very much for the explanation and the bug report!

Just in case it helps: the line shrinking disappears with an additional
"delta=0":

\definefontfamily[face3][rm][gabriola][it={features:{default,
effect={width=1.0, delta=0}}}]

Thank you for the information, Hans!

Could you please also shed some light on the relation/difference among
\{setup,switchto,use}bodyfont?
There seems to be not much documentation on this. Can one conclude, from the
wiki  and the source
code
,
that they are mostly the same, except that \switchtobodyfont is restricted
to the content area, and \usebodyfont is a helper to call \setupbodyfont in
the beginning?

If this is the case, is it recommended to always put a \setupbodyfont[...]
in the beginning, even if it's just a \setupbodyfont[modern]?
One reason might be that the following example somehow enlarges the page
number in the header, intuitively contradicting what is claimed by the wiki
:

\switchtobodyfont[dejavu]
\starttext \switchtobodyfont[dejavu, 24pt]a\stoptext

Thanks!

Thanks, so basically \(last-)userpagenumber is a configurable descendent
of \(last-)pagenumber if I've got the right message from this example?

Thanks, it works!

And I agree that it probably indicates the existence of a bug, since by
changing "\setupbodyfont[deface]" to "\setupbodyfont[dejavu]" in your
example, the problem reappears:

\definefontfamily[face][rm][dejavuserif]
\setupbodyfont[dejavu]
\starttext a\switchtobodyfont[face, 24pt]ɑ\stoptext

Indeed, \setupfooterexts is much clearer for page numbering. Thanks for the
help!.

Btw, do you know whether there is any difference between \lastpagenumber

Hi Pablo,

thanks for the suggestion. Here's the minimal example which shows the
difference:

\definefontfamily[face][rm][dejavuserif]
\starttext\switchtobodyfont[face, 24pt]ɑ\stoptext

this should warn:

fonts   > checking > char ɑ (U+00251) in font
'LatinModernMath-Regular-4' with id 10: missing

while

\definefontfamily[face][rm][dejavuserif]
\starttext\switchtobodyfont[face, 24pt]ɑ\stoptext

produces the expected result despite a harmless warning.

[NTG-context] weird behavior of font.feature.effect

I'm confused by the result of the following example (see attached):

\definefontfamily[face1][rm][gabriola][it={features:{default}}]
\definefontfamily[face2][rm][gabriola][it={features:{default,
effect={}}}]
\definefontfamily[face3][rm][gabriola][it={features:{default,

\item \switchtobodyfont[face3]\it\dorecurse{100}{a b c }
\stopitemize

\stoptext

Could someone explain:
1. What does "effect" mean? Why does "effect={}" embolden the fonts even
though nothing ({}) is given as arguments?
2. Similarly, what does "width" do? Why does "width=1.0" shrink the width
of the line instead of doing nothing?

Re: [NTG-context] How to quote the section names in advance like the table of contents?

[Sylvain Hubert]

Hi Pablo,

thanks for the suggestion, but I was looking for an automated method for
writing a module, therefore manual reference is not feasible here.

Re: [NTG-context] How to define a {\bf}-compatible fake-bold switcher?

[Sylvain Hubert]

Thank you so much, Pablo. This is exactly what I needed.

Could you also tell me where you have learnt these features? I had been
searching for this for hours but \effect was still the best of what I've
got. Indeed, googling 'context+tex+boldened' or 'contextgarden+boldened'
results in nothing useful.

[NTG-context] How to quote the section names in advance like the table of contents?

[Sylvain Hubert]

Dear List,

say I have three sections in the document:

\section{foo} ... \section{bar} ... \section{baz} ...

Now I would like to auto generate a heavily customized table of contents
like the following text, which cannot be done by the stock \placecontent in
general, and put it into the preface:

   This book has 3 sections: foo, bar, and baz.

The text generation should be trivial with lua, but I don't know how such
forward reference of section names works. Could anyone help me with it?

Thanks in advance.

Best,
Sylvain

[NTG-context] How to define a {\bf}-compatible fake-bold switcher?

[Sylvain Hubert]

Dear List,

I'm using a weirdfont that does not have a pre-defined bold variant but
still want to emboldening short extracts of text occasionally, so I've
defined

\defineeffect[thicker][alternative=both,rulethickness=0.3pt]
\define\fakebf{\effect[thicker]}

but in situations like

{\fakebf \definedfont[weridfont] 1 2 3 \definedfont[modern]4 5 6}

the "4 5 6" is faked bold even if latinmodern has a proper bold font.

Could anyone help me define a {\bf}-aware version of \fakebf which can
render the "4 5 6" in the example above in latinmodern's bold?

Thanks in advance.

Best,
Sylvain

\starttext \blank[.25\paperheight] foo \stoptext

But the "foo" still appears at the very top.

Does anyone know why it behaves like that, or whether there is a more

invisible space before the \blank?

Thanks!

tbh I'm not sure. I tried to figure that out by experimenting with

[NTG-context] Why is the textarea not centered by default?

[Sylvain Hubert]

Dear List,

\starttext \showframe \showsetups \stoptext

This minimal example without further configuration shows that the default
value for backspace, textwidth and paperwidth are 2.5cm, 15cm, 21cm resp.,
which means that the textarea is horizontally 0.5cm off the center by
default, and one can indeed see a clear extra margin on the right side.

This seems weird but I'm no expert of typesetting, so does anyone know why
it has been set like that?

Thanks.

[NTG-context] What is "cutspace" and "bottomspace"?

[Sylvain Hubert]

Dear List,

according to https://wiki.contextgarden.net/Command/setuplayout ,
"cutspace" and "bottomspace" are the counterparts of "backspace" and
"topspace", and "If cutspace is set to 0, it is taken to be equal to the
backspace". But in fact, the following document stays the same no matter
what value is given to cutspace.

\setuplayout[cutspace=0.01cm]
\starttext x  \showframe \stoptext

Has anyone actually used these two parameters?

Indeed the checked version is almost twice as slow, and the definition of
\getchecked parameters looks confusingly intimidating to follow, so I give
up figuring out the logic here.

This sounds a bit surprising, since intuitively it takes no less effort to

[NTG-context] Is there any intuitive way of handling missing characters?

[Sylvain Hubert]

Dear List,

Is there any way to give a sequence of fonts to context and let it try one
after another in case of missing characters? Ideally it should be something
like \usefallback[font1,font2,font3,...]

The methods I've found are all way too complicated for someone who does not
really care about fine-grained control over unicode coverage or customizing
a typeface with different serif/sans/math/... combinations from different
typefaces.

Thanks!

Thanks, but this command doesn't seem to add any information on top of the
missing characters that context already reported without the command.

My motivation was to write a module that suggests fallback fonts to the
user, ideally at the moment of encountering a missing character, but at the
end of processing is still acceptable.

I'm not sure I understand what you mean by literal text "function" here,
but in any case isn't it a one-off <1ms cost to parse a function?

For an experienced tex speaker, indeed.
But for an average user who just wants to typeset a bit of fancy stuff,
programming in tex is probably not the most pleasant thing to do and
arguably not the most reasonable either in light of any modern language
like lua.

[NTG-context] How does lua callback work?

[Sylvain Hubert]

Dear List,

I'm trying to intervene whenever context encounters a character that it
cannot render in the current font. I guess this should have something to do
with lua callbacks (pls correct me if I'm wrong), but the document
 does not seem to
elaborate on this.

Does anyone know how the aforementioned task can be done, or how lua
callbacks work in terms of the meaning of the concerned events and
parameters?

Thanks!

Best,
Sylvain

I was aware of this page but have mistakenly inferred from the figure that
the backspace is an automatically calculated sum of other parameters.

Indeed. Thanks for the information!

Re: [NTG-context] How to really set the paper margin?

[Sylvain Hubert]

Never mind, there's a 'backspace=0cm' to be set.

Indeed, but still it would be nice to have a complete and consistent
interface between tex and lua unless it would harm the functionality.

can be way much easier for lua speakers than digging up a bunch of
documentations to figure out whether it's implemented, or how it can be
implemented in a language like TeX, or both which is worse. In such cases,
it would also be much natural to write 'before=function()..' than
'before=\ctxlua{function()...}` unless, again, the former harms the
functionality.

[NTG-context] How to really set the paper margin?

[Sylvain Hubert]

Dear List,

The following example results in a pdf that has a wide margin on both sides
despite the \setuplayout :

\showframe
\setuppapersize[A4][A4]
\setuplayout[margin=0cm, edge=0cm, margindistance=0cm, edgedistance=0cm]
\starttext
hello world
\stoptext

Does anyone know how to really set the paper margin?

Thanks!

Best,
Sylvain

Re: [NTG-context] What does --errors and --noconsole do?

[Sylvain Hubert]

Moreover, is there any way to let context give an error at all when
encountering something like `\setuppagenumbering[position=footer]` ?

Here a fresh standalone installed an hour ago doesn't seem to have the
