[NTG-context] lmtx status

[Hans Hagen via ntg-context]

Hi,

At the ctx meeting we released luametatex, that is, the source code is 
now in the context zip (so it grew a few MB). At the same time Mojca set 
up some contextgarden repositories on github. We're working on a setup 
for users to generate older snapshots, if needed (for instance because 
there are platform changes). She's also working on cmake based 
installation helpers.


One of the things we did was pruning the fonts that are part of the 
installation. With a few exceptions the type one fonts were dropped, 
which is most noticeable for math. There is no need for px and tx fonts, 
they served their puspose in the transition from old style t1 fonts to 
opentype math (when we started with mkiv; we could have dropped them 
already).


We're looking into antykwa math as well as in alternative script and 
calligraphic math alphabets so eventually virtual math from t1 
construction can be dropped completely (in principle if can be 
integrated in the tweak mechanisms) because it is not wirth the effort 
to make them better. That means that we will ship some additional 
companion fonts.


There are math times fonts but they are currently not free and there is 
some effort going on to turn them opentype so we can ditch their setups 
too (we can't test anyway; to some extend that is also true for minion 
math).


High on the agenda is euler (in combination with pagella). This also 
relates to upgraded mixed script and calligraphic support in math. It 
actually means that enabling alternative alphabets will happen a bit 
differently (more naturally integrated as we introduced dedicated ranges 
of slots). Again a side effect is that we have more granular math glyph 
properties (opentype math is too limited but basically frozen so we have 
to get over that and move on). We (Mikael and me) also try to compensate 
for the ommissions and weird things in unicode math but it will take 
some time before we have that all documented.


One of the next uploads will have the pruned / upgraded texmf tree (one 
can always install more in the local tree of course). At some point 
installing from the garden (or from a git clone) will also be supported 
(basically anyone can host a lmtx install).


For the next texlive we hope to switch to lmtx as default and that also 
means that luametatex is the runner then. One can (as currently in lmtx) 
always run luatex with "--luatex".


Als-in-all it's a lot of work but we're getting there.

Hans

If you compile it invoking "context source.tex", use "context --luatex

When I try that I get:

From my experience, this is possible, but maybe not highly probable.

By default, ConTeXt includes fonts by default, as far as I can remember
(I have been using it for over a decade).

Again, I’d very surprised if that were the case.

BTW, is TeX Gyre Heros the font with missing chars in the printed
version of your PDF document?

I think that your printer is having issues with the embedded font in
your PDF document.

There might be a workaround (or a way of testing this), compiling the
PDF document with LuaTeX instead of with LuaMetaTeX.

If you compile it invoking "context source.tex", use "context --luatex
source.tex".

It might be that your printer has problems with the way LuaMetaTeX
embeds the fonts in the PDF (while it has none with LuaTeX).

But the way to know for sure which tools generated your PDF document and
whether fonts are embedded, "pdfinfo your-file.pdf" and "pdffonts
your-file.pdf" are your friends.

Both infos for the following source:

Indeed, that is the case. These formulas are done for single chain
equations. The example given above consists of two formulas, and the
new broken formula type simply does not fit. You can play with more
than one \alignhere, but they will only set new align points. I think
\startalign ... \stopalign is the way to go there. If it is cumbersome
to type all the \NC and \NR one could in principle thing of similar
input as for the simple matrices. Your example then would become

\startalign
A, = 3;
B, = 5;
\stopalign

[NTG-context] Lato typescripts (MKIV/LMTX)

[Adam Reviczky via ntg-context]

Hi,

With the latest upload (2022-09-16 14:41) I wanted to compare some older
projects that I've used with MKIV to the LMTX 2.10.00.

In one of which I am using the Lato 2.0 font (
https://packages.debian.org/sid/fonts-lato).
With MKIV I get the correct output but LMTX complains about not being able
to find the font.

There seems to be an issue with the typescript file type-imp-lato.mkiv.

\setupbodyfont[lato,12pt]

I adapted type-imp-mscore.mkiv to the situation of the fonts in Win10,
and made type-imp-notocjksc.mkiv  according to the Notocjksc fonts.

I refer to type-imp-ipaex.mkiv, and I don't know if the method in it
is outdated. At least, the test results are fine,
though the resulting PDF is a bit too large to be included in this email.

\setupexternalfigure[location={default,local},resolution=30]
\starttext
\externalfigure[hacker]
\stoptext

What am I missing?


The resolution parameter is still not used by default ConTeXt, sorry.

But you can use it with the attached lua file like:


\loadluafile[grph-downsample]
\doifmodeelse{print}{%
\def\Resolution{300}
}{%
\def\Resolution{96}
}%

\setupexternalfigures[
  %directory={./Logos,img},
  conversion=lowres.jpg,
  resolution=\Resolution,
]

Re: [NTG-context] String substitution using regular expressions and backreferences

[Hans Hagen via ntg-context]

On 8/25/2022 9:44 PM, Thangalin via ntg-context wrote:

I've attempted to apply Wolfgang's subtle suggestion of using Lua to parse
the input document using a regular expression via lpeg.replacer. The
replacement itself works fine; however, in doing so the XML document
structure is converted to text, which means that it is no longer possible
to "flush" the XML for further processing as XML. The result is that any
unresolved XML tags are written verbatim to the PDF:

https://i.stack.imgur.com/9ZFND.png

There are two other issues with this approach. First is efficiency. Second
is that the processing function would have to be called for every XML
element to capture the replacement.

My original post asked about applying regex word substitution in a ConTeXt
way, such as:

\definereplacement[SubstMac][ match={Mc([A-Z].*)}, replace={\Mac \\1} ]
\definereplacement[SubstPostmeridian][ match={[Pp]\\.[Mm]\\.},
replace={\cap{pm}} ]

That seems like the cleanest approach because it would work on top of XML
or any other source document. Nevertheless, here is what I tried, which
partially works:

\startbuffer[main]

   “Mr. McAnulty, I presume?”
   Regular text. Irregular text.
\stopbuffer
\startxmlsetups xml:xhtml
   \xmlsetsetup{\xmldocument}{*}{-}
   \xmlsetsetup{\xmldocument}{html|p|em}{xml:*}\stopxmlsetups
\startxmlsetups xml:html
   \startdocument
 \xmlflush{#1}
   \stopdocument\stopxmlsetups
% Paragraphs are followed by a paragraph break, but only if not
nested.\startxmlsetups xml:p
   \xmlfunction{#1}{p}
   \par\stopxmlsetups
\startxmlsetups xml:em
   \dontleavehmode{\em\xmlflush{#1}}\stopxmlsetups
\startluacode
function xml.functions.p( t )
   rep = { [1] = { "McAnulty", "\\Mac Anulty" } }
   x = lpeg.replacer( rep ):match( tostring( xml.text( t ) ) )

   buffers.assign( "p", context( x ) )
   context.getbuffer{ "p" }
end\stopluacode
\xmlregistersetup{xml:xhtml}
\def\Mac{%
   % Determine the sizes of 'M' and 'c'.
   \newbox\MacMBox%
   \setbox\MacMBox\hbox{M}%
   \newbox\MacCBox%
   \setbox\MacCBox\hbox{c}%
   %
   % Cheat to dynamically derive the kerning size by putting Mc in a box.
   %
   \newbox\MacKernBox%
   \setbox\MacKernBox\hbox{\inframed[offset=\zeropoint, width=fit]{Mc}}%
   \def\MacDelta{\dimexpr\wd\MacKernBox-\wd\MacMBox-\wd\MacCBox\relax}%
   \def\MacUWidth{\dimexpr\wd\MacCBox-.75\MacDelta\relax}%
   \def\MacRule{\vrule width \MacUWidth height .04em depth \zeropoint \relax}%
   \def\MacKern{\dimexpr\wd\MacKernBox-\wd\MacMBox-\wd\MacCBox\relax}%
   \def\MacHeight{\dimexpr\ht\MacMBox-\ht\MacCBox\relax}%
   %
   % Write Mc, where c has a macron, to the document.
   %
   M{%
 \dontleavehmode{\raisebox{\MacHeight}\hbox{c}}%
 \kern-1.04\MacUWidth
 \MacRule
 \kern.08\MacUWidth
   }%
}%
\xmlprocessbuffer{main}{main}{}

As shown in the screen shot, this doesn't correctly handle nested XML
elements.

Any ideas on what approach to take to perform a string replacement in
ConTeXt?

Best stay at the xml end ...

\startbuffer[main]

  “Mr. McAnulty, I presume?”
  Regular text. Irregular text.

\stopbuffer

\startxmlsetups xml:xhtml
  \xmlsetsetup{\xmldocument}{*}{-}
  \xmlsetsetup{\xmldocument}{html|p|em}{xml:*}
\stopxmlsetups

\startxmlsetups xml:html
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:p
\xmlfunction{#1}{p}
\xmlcontext{#1}
\par
\stopxmlsetups

\startxmlsetups xml:em
  \dontleavehmode{\em\xmlflush{#1}}
\stopxmlsetups

\startluacode
local rep = lpeg.replacer { [1] = { "McAnulty", "\\Mac Anulty" } }
function xml.functions.p(t)
local dt = t.dt
for i=1,#dt do
local di = dt[i]
if type(di) == "string" then
dt[i] = lpeg.match(rep,di)
end
end
end
\stopluacode

\xmlregistersetup{xml:xhtml}

\startdocument
\xmlprocessbuffer{main}{main}{}
\stopdocument

But this is more fun and probably also more reliable:

\startbuffer[main]

  “Mr. McAnulty, I presume?”
  Regular text. Irregular text.

\stopbuffer

\startxmlsetups xml:xhtml
  \xmlsetsetup{\xmldocument}{*}{-}
  \xmlsetsetup{\xmldocument}{html|p|em}{xml:*}
\stopxmlsetups

\startxmlsetups xml:html
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:p
\xmlcontext{#1}
\par
\stopxmlsetups

\startxmlsetups xml:em
  \dontleavehmode{\em\xmlflush{#1}}
\stopxmlsetups

\xmlregistersetup{xml:xhtml}

\usemodule[gimmicks] % in latest uploads

\chardef\MacAnulty = \getprivateglyphslot{MacAnulty}

\startsetups [box:mcanulty:\number\MacAnulty]

hm, i can have a look at it but we shouldn't break japanese and korean

once you finished all we can see how it can either be integrated or

can you also make a noto typescript for the different chinese setups 
(for some reason the CJK noto's failed so i used the non CJK ones as i 
couldn't locate the right files; one cannot longher download al-of-noto

Dear Wolfgang,
thank you very much for your guidance.
After changing the font settings according to my computer Win10 OS,
the ruby module worked.
But there is another problem, when I use `\setscript[hanzi]`, as follows

%%%begin example

\starttext
\ruby{寖備}{jìn bèi} \ss \ruby{寖備}{jìn bèi} % \tt \ruby{寖備}{jìn bèi}

Re: [NTG-context] Is rendering furigana over horizontal or vertical japanese text doable in ConTeXt?

[黄复雄 via ntg-context]

Currently, the ruby module does not seem to support cjk fonts? I have
a preliminary implementation of furigana(pinyin in Chinese) as:

```lmtx
% define the pinyin font
\definefont[pinyinfont][name:ahpinying*default at 9pt]
% define the pinyin command
\define[2]\pinyin{%
\setbox1 = \hbox{#1}%
\setbox2 = \hbox{\darkgray \pinyinfont #2}%
\newdimen\maxwd%
\ifdim \wd1>\wd2 \maxwd=\wd1 \else \maxwd=\wd2 \fi%
\setbox1 = \hbox to \maxwd{\hfill \box1 \hfill}%
\setbox2 = \hbox to \maxwd{\hfill \box2 \hfill}%
\hskip0pt plus5pt\vbox{\setupinterlinespace[line=0.5em]\box2\box1}%
above line
% \hskip0pt
plus5pt\vtop{\setupinterlinespace[line=0.5em]\box1\box2}% under line
}
```
usage as follows:

```lmtx
\pinyin{寖備}{jìn bèi}
```

BTW, I hav made a vertical typesetting module for Chinese in ConTeXt LMTX,
vertical_typeset.lua in https://github.com/Fusyong/vertical-typesetting

You should modify the set for Japanese characters and punctuations here:

```lua
local function chars_to_vertical(c)
return c >= 0x04E00 and c <= 0x09FFF
end

local puncs_to_rotate = {
[0x3001] = true, -- 、
[0xFF0C] = true, -- ，
[0x3002] = true, -- 。
[0xFF0E] = true, -- ．
[0xFF1F] = true, -- ？
[0xFF01] = true, -- ！
[0xFF1A] = true, -- ：
[0xFF1B] = true, -- ；
}
```

and there is a doc for example, 大学章句.lmtx, in https://github.com/Fusyong/jiazhu,
and jiazhu.lua in same place is a module of Jiazhu (or 夹注, 割注) in ConTeXt LMTX.

But all the comments are in Chinese.

Re: [NTG-context] Is rendering furigana over horizontal or vertical japanese text doable in ConTeXt?

[amano.kenji via ntg-context]

At least, furigana seems covered.

How do I know which document to consult? There are many PDF files that come 
with ConTeXt.

Re: [NTG-context] How can I make a Gentoo Linux package for ConTeXt LMTX?

[amano.kenji via ntg-context]

http://lmtx.pragma-ade.nl/install-lmtx/texmf-context.zip is not versioned.

If the file changes later, linux distributions refuse to use the file.

I wish ConTeXt and LuaMetaTex were versioned and provided `offline` build 
instructions. The vast majority of programs are versioned and can be built 
easily offline. Even if they were distributed as binary files, if they are 
versioned, I can still make linux packages out of them.

Re: [NTG-context] Accessing inserts from Lua in LuaMetaTeX

Hi Hans,

After playing around, I found that this is stored in ".index". I'm able to write to this value just fine, but whenever I
read it I get an error.

This minimal example:

   \starttext
   \setbox999=\vbox{\hrule width 10pt height 10pt}
   
   \startluacode
   local insert = node.new("insert")
   local rule = tex.box[999].list
   insert.list = rule
   insert.index = 4
   
   node.write(insert)
   \stopluacode
   \stoptext
   
works perfectly, but this example:

   \startluacode
   local insert = node.new "insert"
   insert.index = 4
   print(insert.index)
   \stopluacode
   
gives this error message:

   In \insertmode 2 you can't use zero as index.
   
I suspect that this is a bug, but I may just be doing something wrong.

Inserts always felt a little hacky in TeX, so I think that the new
methods are a huge improvement.

Perfect! "tex.getinsertcontent" does exactly what I need.

Really minor, but I would expect that

   tex.insertcontent[4] = 
= tex.insertcontent[4]
   
would be exist and be equivalent to

= tex.getinsertcontent(4)
   tex.setinsertcontent(4, )

I don't think that that will work in this case. I'm doing most of the
work in "pre_output_filter", which is after all of the insert nodes have
been removed from the page and put into their respective boxes. And I
can't postpone setting any inserts until then because TeX needs to know
their height for when it breaks the page. I don't really like how I have
to move the footnotes, but I can't find any better way of doing things.

If you're curious, most of the insert code is in these two functions:

   
   
https://github.com/gucci-on-fleek/lua-widow-control/blob/2bca90/source/lua-widow-control.lua#L612-L669
   
https://github.com/gucci-on-fleek/lua-widow-control/blob/2bca90/source/lua-widow-control.lua#L843-L924

Re: [NTG-context] How can I make a Gentoo Linux package for ConTeXt LMTX?

[Max Chernoff via ntg-context]

Okay, I'm seeing a few separate issues here.

1. Gentoo expects to compile everything from source.

   This isn't an option here since LuaMetaTeX doesn't have any source
   available (yet). So for the time being, you'll need to use the provided
   binaries. These support pretty much every architecture, so this
   shouldn't really be a problem.

2. You want to install ConTeXt LMTX system-wide.

   This is doable with the standard Linux installer script. Just make sure
   to run the script as root and install the files in /opt/context. This is
   what I've done on my system, and it works quite well. 
   
  $ ls -l $(type -p context)
  lrwxrwxrwx. 1 root root 10 Jul 28 00:33 
/opt/context/tex/texmf-linux-64/bin/context -> luametatex*
  
3. You want to install ConTeXt without any network access.

   The easiest way to do this would be to install on a system with
   internet, then just copy over the files. 
   
   If you want to use the "original" installer files, it shouldn't be
   impossible, but probably not too easy either. (All steps below are
   untested)
   
   The platform-independent stuff is all in one big zip, located at:
   
  http://lmtx.pragma-ade.nl/install-lmtx/texmf-context.zip
  
   Unzip this file as "/tex/texmf-context/".
  
   Then you also need to download all of the binaries. You will need to
   download all of the paths listed in this file:
   
  http://lmtx.pragma-ade.nl/install-lmtx/tex/texmf-linux-64.tma
  
   All of those files need to be placed in "/tex/texmf-linux-
   64/bin".
   
   Then to finish installing you'll need to run "mtxrun --generate" and
   "context --make". There are probably a bunch of other steps that I'm
   missing, but this should get you close.
   
   Again, probably easier to just use the regular installer.

4. ConTeXt is really picky about texmfcnf stuff.

   This is an issue that I've had too:
   
  https://github.com/latex3/l3build/issues/232
   
   Pretty much any modification of anything texmfcnf-related with ConTeXt
   will completely prevent it from running. There's a thread discussing the
   problem (but with no real solutions) here:
   
  https://tug.org/pipermail/tex-live/2020-September/046099.html
  
   And a Wiki page here:
   
  https://wiki.contextgarden.net/Custom_Configuration
  
   I agree that this texmfcnf stuff makes it really difficult to install or
   use ConTeXt with any kind of custom paths. Does anyone know how to
   properly configure a texmfcnf with custom paths?
   
Hopefully this is of some help.

\start \setupruby[voffset=-1.2ex]
\type{\setupruby[voffset=-1.2ex]}\quad x \ruby{aaa}{bbb} x

\stoptext
 end example


What about vertical text?


ConTeXt has a mechanism to produce vertical text but there is nothing 
yet which can
be used out of the box to produce a complete document with vertical 
paragraphs.

The insert (etc) handler is more clever and flexible. So, for instance 
we can bubble up inserts. I think you do a preroll so in that case you 
can set the migrations related parameter to not bubble up.


\starttext

\holdingmigrations\numexpr1+2+4\relax

\setbox0\hbox{test \footnote{test} test}

\setbox2\vbox{\unhcopy0}

\holdingmigrations0

\setbox4\vbox{\unhcopy0}

\unhbox0

\unvbox2

\unvbox4

\stoptext

But I have no clue how all that will work out with (lua) code that 
manipulates these things. In list nodes you can consult the pre and post 
fields to what got migrated.

[NTG-context] How to do code listings & sections from XML (AsciiDoc)

[Mojca Miklavec via ntg-context]

Hi,

Hans helped me out with some asciidoc processing a while ago.

I played a bit further, but I'm currently facing two minor issues:

(a) I don't know how to turn program listing (verbatim code) from xml
to (perhaps, vim-based) syntax highlighting (but most importantly, to
make sure that line breaks work properly)

(b) some section titles are missing


Ad (a). The source that looks similar to this:


int main()
{
return 0;
}


should be converted into some kind of equivalent of

% on top
\usemodule[vim]
\definevimtyping [CPP] [syntax=cpp]

\startCPP
int main()
{
return 0;
}
\stopCPP

In the attachment I have the source document (test.adoc), the
generated docbook xml that should be further processed, and test.tex
that one processes to get the final pdf.

Any hints would be greatly appreciated.

Thanks to your guidance, I solved the problem. And I would like to look

Sorry, when you say ` that file for windows 10+`, which one are you
referring to? to scrp-cjk.lua?( yes, I will upgrade it.) or to my lmtx doc
for testing?(It work fine in my Windows 10.) or to type-imp-mscore.mkiv?
(It work fine in my Windows 10, and no mingliu.ttc in it.)

What do you mean by "bad display"? Are the fonts blurry, or are the
shapes all slightly distorted? Your test file displays fine on my
system.

> But there are many Firefox users out there who never use a real 
> pdf-viewer. I would like to show them a good result.

I've been using Firefox (and pdf.js) as my PDF viewer almost exclusively
for the past ~2 years, and I've been using ConTeXt LMTX for about the
same amount of time. I haven't noticed any font issues, so I suspect
that this issue is system-dependant. I've mostly been on Windows for the
past few years, but I'm now on Linux, and I haven't noticed any issues
with either.

> I have no idea if the difference is the cause of the bad display.
> 
> Luckily chrome based browsers shows the fonts without any flaws.

Ok, random guess time (so I may be waay off here):

I think that this is a hinting problem. The TeX Gyre fonts are all
professionally hinted, so what might be happening be that when ConTeXt
is subsetting the fonts, it is removing all of the hinting information,
while LibreOffice is keeping all of the hints. I've opened PDFs from
ConTeXt and LibreOffice in FontForge and the hints are still there, so I
don't think that this is the case, but maybe? The hinting format is also
wildly different between Type 1 and CFF/OTF, so maybe there is just a
bug in one of the font renderers. 

Chrome uses an internal backend to render all of its text, but Firefox
uses system-dependant backends (I think). Most renderers these days will
autohint unhinted fonts using an embedded FreeType so that they still
display somewhat-well. You can adjust the "hinting strength" in
FreeType, which I would guess would usually be set to the maximum. So
LibreOffice includes the font hints and things display fine, and Chrome
uses a bundled FreeType with maximum hinting so things display fine.

Firefox on Windows would need to bundle its own FreeType since there
isn't a system one, and it renders fine in my experience. But Firefox on
Linux would just use the system FreeType. I think that you are on Linux
(?) and the default in Linux is for minimal/no hinting. Now, I've
specifically enabled maximum hinting on my system, and I'm not seeing
any problems with rendering. If you're using Gnome, can you try enabling
"full" hinting in Gnome Tweaks, reboot, then test again? No idea how to
configure this with other DEs, but I'm sure that it's possible. 

Another related guess is that older versions of FreeType maybe had a bug
with parsing/displaying hints. I think that Chrome bundles its own
FreeType which would be recent, but if you're using Firefox on Linux, it
is probably using the system FreeType library. If you're on an older LTS
distro, then the system FreeType may be really old and buggy.

If you're using macOS, I can't really help you too much except for to
say that text rendering on macOS is usually pretty bad unless you have a
really high resolution screen.

So those are my random guesses. Maybe one of them is helpful somehow.

Dear Jan Ulrich,

it may be the font type, the enconding (or who knows what).

> Any ideas how I can achieve this?

I’d rather report the issue (attaching both PDF documents and both
outputs from pdffonts) at https://github.com/mozilla/pdf.js/issues/new.

I reported an issue with PDF.js not displaying the cover of
http://www.pragma-ade.com/general/manuals/xml-mkiv.pdf.

The day after my report the fix was merged.

Just in case it may help,

Pablo

\definefontfamily[mainfont][sans][texgyreheros]
\setupbodyfont  [mainfont,12pt]
\startdocument
  \starttext
  \input lorem
\stoptext
\stopdocument

When I create a pdf from LibreOffice with these fonts I have a good display.

pdffonts shows different font inclusion:


pdffonts libreoffice.pdf
name type  encoding 
emb sub uni object ID
 -  
--- --- --- -
BA+TeXGyreHeros-Regular  Type 1Builtin 
yes yes yes  9  0


pdffonts mwe.pdf
name type  encoding 
emb sub uni object ID
 -  
--- --- --- -
SOVKKO+TeXGyreHeros-Regular  CID Type 0C   Identity-H 
yes yes yes  1  0



Where Libreoffice has type "Type 1", lmtx has "CID Type 0C".

Where Libreoffice has encoding "Builtin", lmtx has "Identity-H".

I have no idea if the difference is the cause of the bad display.

Luckily chrome based browsers shows the fonts without any flaws.

But there are many Firefox users out there who never use a real 
pdf-viewer. I would like to show them a good result.


Any ideas how I can achieve this?

Yes - I had to do the same for a font called Venetian 301 for which I found 
these 4 files:

Venetian301BT-Italic.otfVenetian 301 Italic
Venetian301BT-Bold.otf  Venetian 301 Bold

They each had the fi and fl ligatures, but at different character positions 
depending on which file, and they weren't recognised by default. So I used the 
following code to add them (and add en and em dash substitution as well).

%%  start
\startluacode
 fonts.handlers.otf.addfeature {
 name = "v1", -- these character substitutions will be applied to

 type = "ligature",

 type = "ligature",
 data = {

 [0x2014] = { "-", "-", "-" }, -- em dash
 }
 }
\stopluacode
\definefontfeature [venetian-301-demi-ligatures] [v1=yes,v3=yes]

   \definefontsynonym [SerifItalic] [file:Venetian301BT-Italic] 
[features=venetian-301-BT-ligatures]
\stoptypescript
%%  end

Note that the names v1, v2 and v3 are entirely arbitrary. Also, the 
\starttypescript section sets the font features to be just those I've defined - 
potentially losing whatever 'default' would provide. But since the font doesn't 
seem to have a lot of features in the first place I've so far not noticed any 
problems. I'm sure a real expert could tell you how to retain 'default' and add 
the ligatures, if needed.

just name them 'liga' and default will then do them

Re: [NTG-context] Set up external figure for particular image type

Thank you, Wolfgang.

That looks promising.

SVG files are converted using MetaPost. I thought the following would 
work:


svg=>{\externalfigure[#1][svg][conversion=mp]}


You can probably remove the second argument ([svg]) which was used in my 
example to pass the default values with \defineexternalfigure. Just 
using \externalfigure[#1][conversion=mp] where you pass the default 
values with the second argument is enough.

Re: [NTG-context] Set up external figure for particular image type

[Thangalin via ntg-context]

Thanks, Rik.

Not using Pandoc. I was using Pandoc up until 2020:

https://dave.autonoma.ca/blog/2019/05/22/typesetting-markdown-part-1/

I've since authored KeenWrite ,
which uses flexmark-java  to
generate XHTML documents from Markdown. The only additions I've made to the
library is to add support for Pandoc's annotation syntax (:::).

That said, I'm also a firm believer in not duplicating information. The
information (file name extension) is already available in the documents, so
adding a classification on top of the extension feels redundant.

Thanks for the suggestion!

[NTG-context] New math additional requirement for font definitions

[Alexandre Christe via ntg-context]

Dear list,

I've come across that the new math (which by the way looks really nice)
requires some additional properties to be set in the font definition.

If I take the example file provided by Mikael and add the following lines

\usetypescriptfile[alegreya]
\setupbodyfont[alegreya,11pt]

It fails with the following error message:
"tex error on line 16 in file /Users/aleks/Desktop/Test
Context/someformulas.tex: Math error: parameter 'limitbelowbgap' with id 36
in style 0 is not set"

Libertinus works fine by adding the following two lines

\usetypescriptfile[libertinus]
\setupbodyfont[libertinus,11pt]

Could someone enlighten me?

The font definition file is attached.

BR,
Alex

The below is likely overkill and a good bit of work to setup, but it is
also very flexible. Maybe it suits your needs.

The Markdown-to-XML conversion can be tuned to include all the relevant
information. E.g., you could use pandoc with a custom writer to produce
the XML format of your choice. The link below is an example XML writer
that can be tuned as needed.
<https://gist.github.com/tarleb/634b409be0af62ca210cc9e96d41ca8c>

With that setup, one can modify the `Image` function to produce the
output you need. E.g., match on the file name extension use the library
function `pandoc.path.split_extension` and then change the element type
depending on the extension.

This way you'd have all the important information in your XML.
More info: <https://pandoc.org/custom-writers> and
<https://pandoc.org/lua-filters>.

Of course, you could also use pandoc to go directly to ConTeXt; that is
currently my preferred way of producing PDF from Markdown.

Cheers,
Albert

[NTG-context] fullhz, kerning and glue

[Henning Hraban Ramm via ntg-context]

Hi,
I just added an explanation of "fullhz" to the options in 
https://wiki.contextgarden.net/Command/setupalign.

but I’m actually unsure if it’s right.

In the sources I found:
https://source.contextgarden.net/tex/context/base/mkxl/hand-ini.mkxl

%D At some point we can introduce extreme expansion, i.e. \type 
{\normaladjustspacing\plustwo}.

56
57% 0 = disabled
58% 1 = notused  (thesis)
59% 2 = glyph + kern
60% 3 = glyph only   (default)
61
62\def\font_expansion_enable  {\normaladjustspacing\plusthree}
63\def\font_expansion_enable_k{\normaladjustspacing\plustwo}
64%def\font_expansion_enable_n{\normaladjustspacing\plusone}
65\def\font_expansion_disable {\normaladjustspacing\zerocount}

And "fullhz" in spac-ali.mkxl calls \font_expansion_enable_k.

So, apparently fullhz enables stretching of *kerning* – that sounds to 
me like letterspacing.


OTOH in my notes (and thus in my book) I have the information that 
fullhz enables stretching of *glue*, and I thought that would mean 
whitespace outside of words.


Please enlighten me?

Assuming that Pandoc markdown is being used, you should be able to set 
class attributes on each image. You can then associate external figure 
definitions with specific classes, and process each individually.

When you use XML as input you can add additional code to the setups block
which uses \externalfigure to load the image.


\setupexternalfigures [location={local,global,default}]

Sorry for complaining… :-)
no problem ... maybe we should have a wiki page for 'use this instead of 
that'


as you're playing with it ... there is a lot we haven't yet introduced 
but we will do that stepwise .. here's one


inline formulas like $(x + a + 2)$ will break across lines but 
traditionally \left( .. \right) doesn't which is why these \bigg things 
are there : manual solution for breaking inline math


however, in lmtx these do break across lines but there are of course 
still cases where the penalties injected will discourage it; there is 
agranular penalty system in place but current it is configured as 
traditional tex


now, when a formula doesn't break and is somehow wrapped it doesn't play 
that well with linebreaks but you can cheat: formulas can becoem liek 
glue where the inter atom stretch and shrink can play a more prominent 
role ... here's a test:


% turning small inline formulas into leaders to that we don't get overflows
% or excessive spacing

\startbuffer

test $\darkreda + b + #1 + c + d > 2$ %

\start
\mathforwardpenalties  2  200 100
\mathbackwardpenalties 2  100  50
\getbuffer
\par
\stop

\stoptext

but we currently don't have a high level interface for that; it will be 
part of the more general math penalties setup.


These are just a few of the things to play with.

[NTG-context] Set up external figure for particular image type

[Thangalin via ntg-context]

A document has a mix of SVG and PNG images. Changing the parameters for
`\setupexternalfigure` affects both SVG and PNG images. Consider the
following code:

\setupexternalfigures[
  order={svg,pdf,png,jpg},
  location={local,default,global},
  directory={images},
  maxwidth=\textwidth,
  maxheight=0.4\textheight
]

I'd like to change the `maxheight` option for only PNG images, such as:

\setupexternalfigure[
  method=png,
  maxwidth=\textwidth,
  maxheight=\textheight,
]

However, this affects SVG images as well.

How do you apply different external figure setups based on image type?

Thank you!

This is because you need to pass a list that conforms to what the 
builder expects and the callback that you use doesn't do that for you 
(after all, it also gets hbox content).


There is no 'callback sequence handler' for the par builder (currently i 
see no need for it, also given the extra overhead involved) but this 
what what you can do:


\startluacode
function builders.paragraphs.constructors.methods.preroll_a(head)
local result, info = tex.linebreak(head)
tex.prevdepth = info.prevdepth
tex.prevgraf = info.prevgraf
return result
end
function builders.paragraphs.constructors.methods.preroll_b(head)
local result, info = tex.linebreak(nodes.nuts.copylist(head))
inspect(info)
return true
end
\stopluacode

\defineparbuilder[preroll_a]
\defineparbuilder[preroll_b]

\starttext
\setmainparbuilder[default]   \input tufte \par \input tufte \page
\setmainparbuilder[preroll_a] \input tufte \par \input tufte \page
\setmainparbuilder[preroll_b] \input tufte \par \input tufte \page
\stoptext

The tex.linebreak function gets the properly prepared paragraph and can 
handle it then. On the to do is a to add a 'prepare' helper that adds 
the mandate nodes (par fillers etc) but even then one has to be careful 
where linebreak hackery is applied.

Re: [NTG-context] Count (and limit) glyphs per line?

[Benjamin Buchmuller via ntg-context]

Dear list,

A brief follow-up for (1) itemizations [resolved; but question on ConTeXt hsize 
defaults] and (2) hyphenation [troubles].

(1) To deal with itemizations and other situation where texts are indented such 
as:

   \setuppapersize[landscape,letter]
   \showframe

   \starttext

   \samplefile{knuth}

   \ctxlua{context(tex.dimen["textwidth"])} % 37213340

   \ctxlua{context(tex.dimen["localhsize"])} % 0

   \startitemize[width=5em]

   \item \samplefile{knuth}

   \ctxlua{context(tex.dimen["textwidth"])} % 37213340

   \ctxlua{context(tex.dimen["localhsize"])} % 33283340

   \stopitemize
   
   \stoptext

The following part in the script must be adapted to the local horizontal size, 
I guess: 

if chars >= max_length or width > tex.hsize then

However, tex.localhsize (or tex.dimen["localhsize"]) is 0 when the document is 
initialized. (Maybe a more sensible default would be textwidth rather than 0?)

So, I added:

local localhsize = tex.dimen["textwidth"]
   
if tex.dimen["localhsize"] > 0 then
localhsize = tex.dimen["localhsize"]
end

if chars >= max_length or width > localhsize then

Maybe someone finds this useful in the future.

(2) I'm (now?) running into trouble with hyphenation. With the example above, I 
get

"
The separation of any of these four components would have hurt TEX 
significantly. If I had not partic­-
i-
pated fully in all these activities, literally hundreds of improvements would 
never have been made,
"

In my own document, I also get lines with only a single character or hboxed 
group. I assume, this is because the hyphen is not counted and pushes the 
remainder to a new line where the intended breakpoint again starts another one.

Unfortunately, I don't know what to change; I know a bit about "glyph" and 
"glue", but what is "disc" and would it help here?

Thank you!


Benjamin

Wow, that works like a charm! Thank you, Max! 

It's also a very insightful example of how to use and inject Lua code in the

Re: [NTG-context] Count (and limit) glyphs per line?

Dear list,

I've been confronted with the following 'intriguing' formatting requirement for 
a document:

"
• Type density:  Must be no more than 15 characters per linear inch (including 
characters and spaces).
• Line spacing: Must be no more than six lines per vertical inch.
"

While the line spacing resolves in ConTeXt to

\setupinterlinespace[line=\dimexpr(1in / 6)]

I was wondering if one can limit "type density" as the number of glyphs per 
inch in TeX too? I thought, it is more convenient to rephrase this request (for a 7 in 
textwidth) to limit the number of glyphs per line to 112. (Font must be sans or serif, of 
course ...)

I've tried

\setuplayout[width=112\averagecharwidth]

which, however, results in ~120–130 characters and spaces per line. Pragmatically, I'm 
narrowing the text width to empirically match the requirement, but I'm nevertheless 
curious if there is a Lua/TeX solution to this "problem"?

Just assume the worst case and take the narrowest character:

\showframe

\setupbodyfont[modern] % we need to set the font

\normalexpanded {
\setuplayout
   [textwidth=\the\dimexpr112\fontcharwd\font`.\relax]
}

This talks about "type density", not characters per line. This depends 
mostly on the font (and letterspacing). I.e. you should not use a narrow 
font.

Re: [NTG-context] Count (and limit) glyphs per line?

[Max Chernoff via ntg-context]

I've been confronted with the following 'intriguing' formatting requirement for 
a document:


"Intriguing" is definitely right here. I suspect these guidelines were 
made for typewriters and haven't been updated since.


to limit the number of glyphs per line to 112. 


112 characters per line sounds much too long anyways.

From "The Elements of Typographic Style":

If you use something like

\setuplayout[width=80\averagecharwidth]

then your lines will for sure have fewer than 112 characters and will 
probably be more readable too.



I'm nevertheless curious if there is a Lua/TeX solution to this "problem"?


Option 1: Use a monospaced font. Then 112 characters per line <=> page 
width = 112em.


Option 2: A hacky Lua solution

\startluacode
local max_length = 112

local glyph_id = node.id "glyph"
local disc_id = node.id "disc"
local glue_id = node.id "glue"

function userdata.limiter(head)
language.hyphenate(head)

local chars = 0
local width = 0
local n = head
while n do
if n.id == glyph_id or n.id == glue_id then
chars = chars + 1
width = width + n.width - (n.shrink or 0)
end

if chars >= max_length or width > tex.hsize then
local back_chars = 0
local end_disc = nil

while n do
if n.id == glue_id then
local penalty = node.new "penalty"
penalty.penalty = -1
node.insertbefore(head, n, penalty)
break
end

if not end_disc and n.id == disc_id then
end_disc = n
end

if end_disc and back_chars >= 5 then
end_disc.penalty = -1
break
end

if n.id == glyph_id then
back_chars = back_chars + 1
end

n = n.prev
end

width = 0
chars = 0
end

n = n.next
end

return head
end

nodes.tasks.appendaction(
"processors",
"before",
"userdata.limiter"
)
\stopluacode

\setuppapersize[landscape,letter]
\showframe

\starttext
\setupalign[flushleft]

\setupbodyfont[14pt]
\samplefile{knuth}

\setupbodyfont[12pt]
\samplefile{knuth}

\setupbodyfont[10pt]
\samplefile{knuth}

\page
\setupalign[normal]

\setupbodyfont[14pt]
\samplefile{knuth}

\setupbodyfont[12pt]
\samplefile{knuth}

\setupbodyfont[10pt]
\samplefile{knuth}
\stoptext

This code will ensure that no line ever exceeds "max_length" characters. 
It uses a greedy algorithm instead of the standard TeX algorithm for 
line breaking, but it still produces mostly decent results.

[NTG-context] Count (and limit) glyphs per line?

Dear list,

I've been confronted with the following 'intriguing' formatting requirement for 
a document:

"
• Type density:  Must be no more than 15 characters per linear inch (including

• Line spacing: Must be no more than six lines per vertical inch.
"

While the line spacing resolves in ConTeXt to

\setupinterlinespace[line=\dimexpr(1in / 6)]

I was wondering if one can limit "type density" as the number of glyphs per

Pragmatically, I'm narrowing the text width to empirically match the

[NTG-context] Problems with MetaFun Transparency Groups

[Stefan Haller via ntg-context]

Hi everyone!

I have a question regarding transparency groups in MetaFun. As a toy example, I
want to draw a grid of lines where the whole grid should have an opacity of 25%.

If I draw intersecting lines individually with `withtransparency(1, .25)` the
overlapping parts will have a total opacity of 50%. However, I want to draw the
whole grid as one group and then blend it as a whole so that the whole grid is
evenly colored when blended. According to the MetaFun manual we should be able
to get the desired effect with the `asgroup` operator applied to a picture.
(Actually, the manual says the operator is called `grouped` but the source code
of the graphics above uses the `asgroup` operator [1].)

The `asgroup` does in fact insert a transparency group into the PDF output:

> << /Type /XObject /Subtype /Form /FormType 1 /Group << /S /Transparency /I 
> false /K false

However, the group does not seem to be blended as one group and we can still
see that the overlapping parts are darker than the other parts of the line.
Something seems to be off. Looking at the compiled manual also shows that the
transparency groups are not working (both parts of the arrow, the head and the
tail, are blended independently and not as a group).

When I recreate the graphics in Tikz/PGF everything works. The resulting PDF
output looks similar, at least with my limited understanding of PDF format I am
unable to understand the differences.

The full example is attached below the text of my mail. The Tikz example on the
fifth page shows the desired result.

Do I misunderstand the syntax of transparency groups in MetaFun? Or is there
some other problem? Maybe someone can point me in the right direction.

Thanks in advance!
Stefan Haller

Re: [NTG-context] Workshop at FrOSCon

I'm a beginner in context (and not a programmer by profession) and
installing lmtx on windows was very easy for me. the steps are on the
wiki https://wiki.contextgarden.net/Installation and it is as easy as
it is written there. I've been using context thanks to these
installation steps on win 7 and win 10. I'm not sure what the
targetgroup at the conference is, but if the people there ever used a
commandline, they should be good to go. once you install, you open the
commandline using Win+R and then type "cmd". Once in the cmd, you only
need to know the command "cd" (change directory) to navigate to the
folder where the .tex source is, so e.g. "cd c:\users\x\documents\"
and then run "context test.tex". That is the manual way.

I use sublimetext as text editor and made a new build for it, that
when I press Ctrl+B saves all changes in the open file/folder and runs
context on the open file and previews the pdf in mupdf that is zoomed
to be 1:1 paper:print on my dpi. It's a bit like TeXworks, just press
button and see the pdf, because mupdf automatically overwrites the
open pdf without asking.

It's 4 hours by train for me to Bonn and I'm not sure whether I'm a
good candidate to teach people context due to my low skill, but I can
surely teach you how to install lmtx on windows if you like (we could
call or sth).

Best,
Andrej

Re: [NTG-context] issue with scite module

[Max Chernoff via ntg-context]

For the sake of consistency (with buff-imp-xml.lua), I think the patch
should read

> [...]

+local alsoname = lpatterns.utf8two + lpatterns.utf8three +
lpatterns.utf8four


I think that that pattern is a little too broad, since it will match any 
non-ASCII Unicode character. Things like U+202E (xkcd.com/1137), U+00A0 
(no-break space), etc are valid UTF-8 characters, but not valid XML tag 
names. Neither of these two characters are matched by the TeX catcode 
check. This doesn't make any real difference for a syntax highlighter 
though.



+local name = (R("az","AZ","09") + S("_-.") + + alsoname)^1


There's a doubled plus in the middle there. The patch works when I 
remove it.



But I’m afraid I cannot make it work on my computer (Linux64).

On another Win64 computer, both patches worked perfectly fine.


Hmm, that's really weird. Both patches work for me on my main Win64 
computer (after I fixed the extra plus). I also pulled the 
"contextgarden/context:lmtx" Docker image (Debian sid), and both patches 
worked there too. I get this from inside the container:

Is this perhaps a weird locale or encoding issue? Maybe try compiling with:

LC_ALL=C.UTF-8 LANG=C.UTF-8 context test.tex

or

LC_ALL=POSIX LANG=POSIX context test.tex

I'm surprised Linux is the one not working here, since it's usually 
Windows that has text encoding issues with its weird hybrid of DOS 
codepages and UTF-16+BOM.


The only other thing that I can think of is a weird library issue with 
your distro, but LuaMetaTeX is statically linked. Not sure what else to 
check here.

Hi Pablo,

with LMTX version 2022.05.11, both elements are displayed, but the first 
in blue, the second in red. Apparently the scite highlighter doesn’t

Re: [NTG-context] Callbacks (and nodes) in LuaMetaTeX

[Max Chernoff via ntg-context]

Hi list,

I haven't had any luck solving any of the issues from my previous email:

[NTG-context] Callbacks in LuaMetaTeX
https://mailman.ntg.nl/pipermail/ntg-context/2022/105566.html

Admittedly, my problems are fairly obscure (and likely self-inflicted), 
but any suggestions would be greatly appreciated. I've updated my 
ConTeXt installation to the latest version (mkxl 2022.05.11 11:36), but 
this doesn't seem to have changed anything.


Further to the previous email, I have one (semi-related) additional 
question:


6. The LuaTeX manual says that the subtype of "ins" nodes is a number
   corresponding to the insert class. This appears to work correctly.
   The LuaMetaTeX manual says the same thing about "insert" nodes;
   however, the subtype of "insert" nodes appears to always be zero.

   Using this code:

   \startluacode
   local traverse_id = node.traverse_id or node.traverseid
   local insert = node.id"insert" or node.id"ins"

   function test(head)
   for n in traverse_id(insert, head) do
   inspect(n)
   print(n.subtype)
   end

   return head
   end

   nodes.tasks.appendaction("finalizers", "after", "test")
   \stopluacode

   \starttext
   One \footnote{Two} \insert123{Three} Four.
   \stoptext

   In MkIV I get:

   Is there any way to get an insert's class from its node in MkXL?

Please let me know if you have any ideas for this or any of the earlier 
questions.

Re: [NTG-context] Issue with interactive checkboxes[solved]

[Jan-Erik Hägglöf via ntg-context]

HI Again!

I discovered what went wrong, such a silly syntax error, here comes a working 
code:

\setupinteraction[state=start]

\definesymbol[yes][{\externalfigure[check-mark-svgrepo-com.svg][conversion=mp]}]
\definesymbol[no][]

\newcount\chk
\def\checkmark{%
\global\advance\chk by 1
\setupfield[setup1][width=0.5cm, height=0.5cm,rulethickness=1pt, corner=round, 
framecolor=red]%
\definefield[checkme\the\chk][check][setup1][yes,no][no]%
\field[checkme\the\chk]%
}

\starttext

\checkmark\

\checkmark\

\checkmark\

\stoptext

Sorry to bother the list but maybe it is helpful for someone.

Regards

Re: [NTG-context] Issue with interactive checkboxes

[Jan-Erik Hägglöf via ntg-context]

I’ve tried this

\setupinteraction[state=start]

\definesymbol[yes][{\externalfigure[check-mark-svgrepo-com.svg][conversion=mp]}]
\definesymbol[no][]

\newcount\chk
\def\chk{%
\global \advance \chk by 1
\setupfield[setup1][width=0.5cm, height=0.5cm,rulethickness=1pt, corner=round, 
framecolor=red]%
\definefield[checkme\the\chk][check][setup1][yes,no][no]%
\field[checkme\the\chk]%
}

\starttext

\chk

\chk

\chk

\stoptext

But it gives the error ” You can’t use \global after \advance”

But this example works fine

\setupinteraction[state=start]

\newcount\clozecount
\def\mycloze{%
  \global \advance \clozecount by 1
  \definefield[uniqcloze\the\clozecount][line]%
  \field[uniqcloze\the\clozecount]%
}

\starttext

[NTG-context] PDF/A-3, XMP and Factur-X

[Henning Hraban Ramm via ntg-context]

Hi again,

I’m looking into extending my ConTeXt-made invoices with embedded XML 
data according to the DE/FR Factur-X standard (in Germany also known as 
ZUGFeRD).


Does anyone have some experience with that?

For that, I need PDF/A-3(a) compliant documents – current documentation 
is only on PDF/A-1(a), but that doesn’t seem to be the problem.


Now I’m supposed to put additional information into the XMP metadata.
I found lpdf-xmp.lua; but it seems like I can’t just use

\startluacode
lpdf.addtoinfo("TEST","Hraban was here!")
lpdf.addxmpinfo("UStID","123456")
\stopluacode

Would I need to add my tags to the mapping table of lpdf-xmp.lua?

Or circumvent it after a look at the function concerned:

function lpdf.addxmpinfo(tag,value,check)
local pattern = permitdetail(tag)
if type(pattern) == "string" then
xmlfillin(xmp or valid_xmp(),pattern,value,check)
end
end

If I try to use xml.fillin, I apparently need the name of the current 
xml file, but valid_xmp is a local function. If just use the default...


xml.fillin("lpdf-pdx.xml","metadata","UStID","123456")

... at least I find no traces of that key in the extended metadata 
dialog of Acrobat Pro 9. I also tried different values like "xmp" 
instead of metadata. Clearly I don’t understand what I’m doing here ;)


Is there a check against some schema involved?

It looks like I should include an additional XMP schema for Factur-X 
with the URI "urn:factur-x:pdfa:CrossIndustryDocument:invoice:1p0#", 
prefix "fx". How can I do that?


This is the example from the docs:


INVOICE
factur-x.xml
1.0
EXTENDED


Then I’d use \attachment to include my "factur-x.xml" invoice (that I 
must generate from my Lua invoice code), but that’s a task for another 
day ;)

Re: [NTG-context] Can I just put a footnote without marking in the main text?

[Ross via ntg-context]

After some visualisations, I found that my token \titlefootnotes will
ALWAYS generate two lines if there is/are any non-zero number of footnotes
there. Interesting. So I need a \newif that each time a \thanks or \email
is invoked, it'll set to true and I'll unskip the 2\lineheight afterwards.

I still don't know why this \kern macro won't have any effect if it's
inside a token or a \startsetup.

Re: [NTG-context] Can I just put a footnote without marking in the main text?

[Ross via ntg-context]

Dear Massi,

Thanks for your solution. But the thing may be related to the \appendtoks
macro. It doesn't work to put just \setnotetext there.
\note works fine, so that's the reason I need the "full functional macro".

Maybe I didn't get the point, so if it's not too much to ask, could you do
it on my MWE?

PS: sorry I have to use another email account because my institute mailbox
took forever to get the message before my government (China) finishes
auditing it.

Best wishes,
Zhichu

That's strange: I have LMTX 2022.05.11 11:36 and have no issues with this 
'patch'. I too have thousands of references across documents, so could not 
convert the tags to lowercase, and this patch works for me. 
I am attaching a diff here. I hope you made the format (context --make) after 
applying the changes.

Splendid (as always)! Definitely a better solution for Stefan's document.

I added a section in the wiki making a note of this:
  https://wiki.contextgarden.net/TABLE#Headers_with_TABLEs

Thanks Wolfgang! Until now, I did not even know of the 'nested' type for 
TABLE.

Hi Alex,

you added an extra option group here:

  \definefallbackfamily [alegreya] [math] [Alegreya]
[superscriptsandsubscripts] [force=yes]

I think this may read:

  \definefallbackfamily [alegreya] [math] [Alegreya]

Just in case it might help,

[NTG-context] Custom type-imp file creating empty lines

[Alexandre Christe via ntg-context]

Dear list,

I've played a bit with a custom type-imp file (partly inspired from the
wiki https://wiki.contextgarden.net/Alegreya_Typescript). However, the file
I ended up with seems to create some empty lines at the beginning of the
document (if I use the default or another font this vanishes, so it really
comes from that file). Could anyone enlighten me?

The file is attached.

BR,
Alex

[NTG-context] \placenotes ends up in wrong place when mixing one- and two- column layouts.

[Zhichu Chen via ntg-context]

Thanks Hans, works perfectly.


Sorry for the late reply. Still working on the template and got another 
one. Again, sorry.



The journal is in two-column form and the title, authors, and addresses 
are spanned to


the full width. Very common. But the title may acknowledge to some 
fund(s) and the


authors may have email addresses. If I use \note[thanks] and 
\note[email] to do that,


only the markers are shown. That's expected. So I tried to put 
\postponenotes before


the title and insert\placenotes[thanks] and \placenotes[email] after 
\startcolumns. The


notes did show up but in wrong position.


I hope there's another magic switch, or I have to put the marks in the 
title head and


put "real" but invisible notes in the two-column texts.



Thanks again, Hans.


Yours,

Zhichu

I really like the way wherebibtextreats words enclosed in curly

Re: [NTG-context] how to choose a font variant "book" / LMTX

'both' would be the way to go, how can I set this up?

I don’t use typescripts just the definefontfamily and I suppose the book 
variant belongs to the family but is maybe an unloved relative ...

Re: [NTG-context] how to choose a font variant "book" / LMTX

[Henning Hraban Ramm via ntg-context]

Do I understand correctly that you want the "Book" variant as regular? 
Or do you need both?


Have a look into typescripts, e.g. 
https://wiki.contextgarden.net/Alegreya_Typescript

You probably won’t need the features.

[NTG-context] Issue in btx rendering

[śrīrāma via ntg-context]

Hi,

[my current version: 2022.05.02 16:19]
With the past two-or-so uploads, btx output seems to be broken in some cases. 
Compiling the below example

  \usebtxdataset[refs.bib]
  \usebtxdefinitions[aps]

  \starttext
  This reference has a tag which is in camel-case:
  \cite[Nielsen2011_ChernoffInformationExponentialFamilies]

  On the other hand this reference has a tag which is lower-case:
  \cite[vaart1998_asymptoticstatistics]

  \placelistofpublications
  \stoptext

along with the bibtex file (refs.bib attached here), only the second citation 
entry has a properly rendered bibliography entry while the first one does not. 
Notably, any bibtex entries whose tags are not all lowercase (ASCII) are not 
rendered correctly. Instead, in the log I get

publications > unknown tag 'nielsen2011_chernoffinformationexponentialfamilies' 
in dataset 'default'

Almost all my entries in bib files are in camel-case since I find that to be 
easier to read and it gives me a better clue of what the item is. With some 
recent uploads I noticed that in publ-ini.lua 'tag' and 'field' entries were 
string.lowered(). Upon removing those statements, I am able to get the proper 
output.

I also have certain bib files where the entries are not at all in ASCII (so I 
am not sure what the code might do there, I did not check in detail). I hope I 
can continue to use camel case for the tags (if its not too much to ask): is 
there some additional setting that I should change to allow this so that the 
output is rendered correctly?

Thanks,

I've just checked, \commalistsentence is already on the wiki, but you have to 
know it exists. (I'll check whether I can link to that page from somewhere.)

But there's no (high-level) way to apply certain commands to this list 
elements, right? 
Background: My real use case is a bit more complex. I use comma separated lists 
to store author lists, but the authors themselves are saved in structured 
variables. So, I'll need to reassemble the different name parts first.
So, nothing like 
\commalistprocessandmakesentence[a,b,c]\commandforfirst\commandforinbetween\commandforlast
Probably to specific, right?

[NTG-context] $\sin \theta$ behave differently in metafun

[Jeong Dal via ntg-context]

Dear all,

I use $\sin \theta$ and $\cos \theta$ behave differently in text and in metafun.
It works well sometime before but it doesn’t  in metafun now.
What is wrong in my example?

Thank you for reading.
Best regards,

Dalyoung

Here is a MWE.

\startbuffer[pointCircle]
numeric u; u:=1cm;
pair A,B,C;
draw fullcircle scaled 4u;
A := dir(25)*2u; 
label.top(textext("$P=(\cos\theta, \sin\theta)$"), A);
B := dir(-25)*2u;
label.bot(textext("$Q=(\cos(-\theta), \sin(-\theta))$"), B);
C := (xpart A, 0); label.lrt(textext("$A$"), C);
label(textext("$O$"), origin);
\stopbuffer
\starttext
I'd like use $\sin$ and $\cos$ in the metafun. But it shows strange text 
instead of $\sin$ and $\cos$. 

\processMPbuffer[pointCircle]
