Honestly, I don't know how Knuth resisted putting this in plain TeX.

Plain TeX is a format so ther it would be easy, just define

\newdimen\potrzebie  \potrzebie = 422042sp

but for a real unit you need to adapt the original engine and that will 
not happen because it's in bug fix only mode.


Anyway, you can try it in lmtx:

\startTEXpage[offset=1dk]
\number\dimexpr1dk
\stopTEXpage

As introduced in:

https://www.tug.org/TUGboat/tb42-3/tb132hagen-dk.pdf

Like the ts is makes a nice offset.

The inch is properly defined as *exactly* 2.54cm.
So the foot is a proper unit defined as 12*2.54cm.

Manipulating fractions, I stated, is the entire point of Imperial
measurements.

Now go figure: Physical Review Letters once objected to my publishing a
graph without units on the abscissa. I satisfied the editor by adding
$[m\times m^{-1}]$ (my graph was in radians).

Well, the Polish oversight seemed to a agree and the team was awarded by

about that later. The unit was applied by the main presenter when the 
big cake got cut into pieces measuring 4es ^ 2 which i admit is a bit 
less than 4in ^2.


But, if you're really into old units we can measure your feet and 
replace "max 19 feet" message by "max 20 braslaus".


Actually you can do a sqrt:

\starttext
\the\floatexpr\pfsqrt 2\relax

\the\pfsqrt 2\relax

\scratchdimen\floatexpr\pfsqrt 2\relax
\the\scratchdimen

\scratchdimen\pfsqrt 2\relax
\the\scratchdimen
\stoptext

but you already knew that.

Works fine at my end. I also adapted the arch AUR package to use the 
install-tikz option (earlier I was installing these packages by wget as part of 
the installation process).

[NTG-context] upload

Hi,

I uploaded a version that provides

  mtxrun --script install-tikz

that when run in the tex root (.../tex) will fetch some tikz stuff from 
ctan and puts is in texmf-modules. After installing it wipes the files 
that make no sense (or can interfere or might be harmful) but I didn't 
check that extensively. Finally it remakes the file dastabase. I don't 
know if more needs to be installed. It assumes curl to be present (as 
library or binary). It's a rather stupid script but (I guess) good 
enough for what it is supposed to do.


I can add more (like other modules) in which case it will be renamed.

For a few months now, all features of tikz have not been working with LMTX. 
After help from Hans and a bit of trial and error, I think that figured out 
what was going wrong with the catcodes in m-tikz: Since the texcatcodes are 
different from what tikz expects, the catcodes have to be set inside 
\starttikzpicture (in addition to before the loading of tikz files, which was 
already being done).

I am attaching the working m-tikz.mkxl file.

I have tested this on my course notes, which make extensive use of simple tikz 
block diagrams and pgfplots graphs. Perhaps others who were having issues with 
tikz could test if this fixes everything and, if so, we can add this to the 
distribution.

So, what is needed from tikz?

"graphics/pgf/base/pgf.tds.zip",
"graphics/pgf/contrib/pgfplots.tds.zip",
"graphics/pgf/contrib/circuitikz.tds.zip",

Is there more that should be installed as reasonable basic set? I made a 
script that does fetch/installs it (and also wipes latex / plain 
/useless stuff afterwards including some shell etc scripts as we don't 
want those either - security risk etc -).


Not being a tikz user I have no preferences but we can add some test 
files to the test suite if needed.

Re: [NTG-context] OBSD 7.3 binary locally compiled… what next?

Compilation succeeded, looks like the binary lies in
/usr/local/context/source/luametatex/build/native/luametatex

What's the next step?

you should make

tex/texmf-openbsd7.3-amd64

and put 5 files there:

luametatex
context -> luametatex
mtxrun  -> luametatex
mtxrun.lua
context.lua

you can take the lua files from

tex/texmf-openbsd7.2-amd64

or you can just rename the 7.2 path to 7.3 and move luametatex there

(of course you then also need to adapt your path to the new situation)

What's the next step?

There was this message:

Does this mean I have to create that part of the tree by hand (which

Should I run install.sh – which I not did, assuming maybe wrongly that

[NTG-context] new units

[Hans Hagen via ntg-context]

Hi,

We now officially have three new units. These were officially introducd 
at the 2023 BachoTeX meeting in a presentation where the chair of the 
four person strong team also did the final live callibration (using the 
edithorial callibration instrument made for that purpose). An upcoming 
article in TB will explain the details of the process and also a careful 
mathematical annalysis of how we reached the right value with a high 
precission. The actual implementation is the most boring part.


\starttext

\startTEXpage[offset=1ts]
Hello World!

\the\dimexpr 1ts

\the\dimexpr 1es

\the\dimexpr 1eu

\eufactor20

\the\dimexpr 1eu
\stopTEXpage

\stoptext

The es (Edith) unit replaces the inch, and the ts (Tove) is one tenths 
of than (just like we have cm and mm). The eu (European Unit) is an 
adaptive one that defaults to 10 ts == 1es and can be multiplied by 
setting the \eufactor (default 10) which makes it possible to define 
layouts that easilly scale to different output media (important for the 
mobile phone / table generation).


This means that MWE that use inches will likely no longer be considered 
valid and probably will be dealt with slower (or just ignored).


These units can be used in the current upload. In a next upload the "19 
feet max" message that tex issues when reaching a maximum will be 
adapted to a more realistic variant. (Actually, because tex has no foot 
unit, we could as well replace that with a more impressive little feet 
unit but we forgot to measure the smallest foot present which i guess 
was about 3 es so the limit is then some 75 bare theodores.)

A 5 year old circuitikz module in $TEXMFHOME, which was interfering! Everything 
appears to be working now at my end as well.

@Hans, could we add the m-tikz.mkxl file that I sent to the distribution.

[NTG-context] define math function with \, inside

[Stefan Haller via ntg-context]

Hi all,

I wanted to define a custom math function (similar to log etc.) for
argmax. However, I wanted to have a small space between "arg" and "max"
and limits should work properly. I am using a up-to-date LMTX installation.

Without the first constraint it's easy:

> % old way:
> \definemathcommand[argmax][limop]{\mfunction[argmax]}
> % new way, discoverd by looking into math-def.mkxl
> \definemathfunction[argmax]

However, both methods do not work if I want to have "arg\,max" printed
(error about \endcsname missing). With mkiv the first method works and
can also be found in the wiki[1].

What's the current way to define such a custom math function?

Thanks!

Many thanks for your fast reply, Bruce.

For some strange reason, binaries weren’t updated to latest ones.

Copying them from a brand-new install fixes the issue.

I wonder whether other Linux64 users experienced this.

(https://mailman.ntg.nl/pipermail/ntg-context/2023/date.html#108157).

Although the list has been distributing messages to subscribers and I
received them, I guess that the server software update might have
something to do with this.

Just for the record, I contacted Taco privately two weeks ago. No reply,
but I understand that obviously he is busy with other things.

Before sending him another message on the issue, I would like to ask
whether anyone could confirm that recent messages (from this week)
aren’nt being listed at
https://mailman.ntg.nl/pipermail/ntg-context/2023/date.html.

Many thanks for your help,

Pablo

[NTG-context] cannot generate format file with current latest

[Pablo Rodriguez via ntg-context]

Dear list,

I have just updated to current latest (2023.04.27 17:04).

I always delete cache with "mtxrun --generate" after an update.

When I try to create the format file with "context --make --all", I get
the following error message:

lua error   > lua error on line 645 in file context.mkxl:

token call, execute: ...ext/base/mkxl/cldf-pos.lmt:18: attempt to index
a nil value (global 'posit') stack traceback:
...ext/base/mkxl/cldf-pos.lmt:18: in local 'code'
...ext/base/mkiv/util-lua.lua:96: in field 'loadedluacode'
...ext/base/mkiv/luat-env.lua:108: in field 'luafilechunk'
...ext/base/mkxl/luat-cod.lmt:82: in function 'lua.registercode'
[ctxlua]:1: in main chunk

A number should have been here; I inserted '0'. (If you can't figure out
why I needed to see a number, look up 'weird error' in the index to The
TeXbook.)

Could anyone confirm the issue?

Many thanks for your help,

Pablo

Thank you.

How do I change that in my setup?

My setup is creating the same stuff in different languages from XML

following setup (cyrillic and greek shown as the other languages with 
different character sets I use)


\startmode[JA]
\setuplanguage[ja][patterns={ja}]\mainlanguage[ja]

When your document prints only text in a single language change the 
setup above to


    \startmode [JA]
        \setscript [nihongo]
        \mainlanguage [ja]
    \stopmode

but for documents which use multiple script/languages at the same time 
replace the previous setup with


    \startsetups [japanese]
        \setscript [nihongo]
    \stopsetups

    \setuplanguage [ja] [setups=japanese]

and add \language[ja] before japanese text to ensure linebreaking is 
enabled.

lua code creates METAPOST code which creates images with embedded ConTeXt

text.

Gerben Wierda via ntg-context schrieb am 30.04.2023 um 09:12:
I am currently testing with a Japanese translation of something I 
originally created in English using the ConTeXt engine (LMTX).


I run into the fact that Japanese has no use for whitespace, so most 
of the time TeX has no idea where to break. Is there something I can 
tell ConTeXt to solve this for me or do I have to alk with the 
translator to put whitespace in the correct places (kind of breaks the 
automatic linebreaking of TeX, though)?


Below is a example with some dummy text for a document which contains 
only japanese. The main points are


    1. to use a font which is suitable for japanese, e.g. Noto 
Serif/Sans CJK JP and


    2. enable line breaking with \setscript[nihongo].

The \mainlanguage setting is only needed to get japanese labels for 
chapter, float titles etc.


When you have a document with mixed scripts the approach below doesn't 
work because
spacing around braces and other punctuation marks is wrong for non 
japanese text,
this can be fixed but you have to include language switches in your 
document.

[NTG-context] Linebreaking in Japanese in ConTeXt

[Gerben Wierda via ntg-context]

I am currently testing with a Japanese translation of something I originally 
created in English using the ConTeXt engine (LMTX).

I run into the fact that Japanese has no use for whitespace, so most of the 
time TeX has no idea where to break. Is there something I can tell ConTeXt to 
solve this for me or do I have to alk with the translator to put whitespace in 
the correct places (kind of breaks the automatic linebreaking of TeX, though)?

Is it possible to create a standalone test that does not depend on a bunch of 
datafiles that need to be downloaded?

This came up before [1]. The solution is to use \primed{...}

Thanks for testing. I'll double check what was going wrong with my circuitikz

These are already part of the distribution. Just one caveat: you need to use

\usemodule[tikz]
\usemodule[pgfplots]

Directly loading 

\usemodule[pgfplots]

will not work as the t-pgfplots module explicitly loads t-tikz, which does not 
work with LMTX.

Re: [NTG-context] LuaMetaTeX doesn't find files when symlinked

[Max Chernoff via ntg-context]

Hi Lynx,

This is probably not the same issue, since the path "context-linux-
64/bin/mtxrun" suggests that that isn't a symlink. (Well, it is a
symlink mtxrun => ./luametatex, but that email is about multi-level
symlinks like /usr/bin/context => /usr/local/texlive/2023/bin/x86_64-
linux/context => ./luametatex)

To compile a document, you almost certainly want to use "context"
instead of "mtxrun". So try changing the user command to
"/usr/local/ConTeXt_Standalone/context-linux-64/bin/context".

If that doesn't fix anything, run

   $ /usr/local/ConTeXt_Standalone/context-linux-64/bin/mtxrun --generate
   $ /usr/local/ConTeXt_Standalone/context-linux-64/bin/context --make
   
and try again.

If it still doesn't work, then what do you get when you run

   $ /usr/local/ConTeXt_Standalone/context-linux-64/bin/context --nofile

Circuitikz still doesn't work. Even loading the module fails. Not sure why this 
is happening:

\usemodule[circuitikz]

gives:


tex error   > tex error on line 77 in file 
/opt/luametatex/texmf-context/tex/context/modules/mkxl/m-circuitikz.mkxl: 
Package pgfkeys Error: I do not know the key '/tikz/resistor', to which you 
passed 'american', and I am going to ignore it. Perhaps you misspelled it

 \pgfkeys@error

which is a bit strange as the key should have been '/tikz/circuitikz/resistor' 
rather than 'tikz/resistor'.

[NTG-context] tikz + lmtx

[Aditya Mahajan via ntg-context]

Hi all,

For a few months now, all features of tikz have not been working with LMTX. 
After help from Hans and a bit of trial and error, I think that figured out 
what was going wrong with the catcodes in m-tikz: Since the texcatcodes are 
different from what tikz expects, the catcodes have to be set inside 
\starttikzpicture (in addition to before the loading of tikz files, which was 
already being done). 

I am attaching the working m-tikz.mkxl file. 

I have tested this on my course notes, which make extensive use of simple tikz 
block diagrams and pgfplots graphs. Perhaps others who were having issues with 
tikz could test if this fixes everything and, if so, we can add this to the 
distribution.

[NTG-context] LuaMetaTeX doesn't find files when symlinked

[Max Chernoff via ntg-context]

Hi Hans,

With the LuaMetaTeX-based ConTeXt wrapper, it's not generally possible
to run ConTeXt from a symlinked binary in another directory. This shows
up if someone makes symlinks in "/usr/bin" so that they can avoid adding
anything to their $PATH.

If you make run a symlink to the LuaMetaTeX-based ConTeXt wrapper, it
looks for texmfcnf.lua relative to the symlink location, not the symlink
target. With the old LuaTeX/kpse-based wrapper, the script would look
for texmfcnf.lua relative to the symlink target.

I know that my description above is terrible, so here's a demo:

   $ bin=$(mtxrun --expand-var TEXMFOS | head -1)/*
   $ cd $(mktemp -d)
   $ ln -s $bin/luatex $bin/luametatex $bin/context $bin/context.lua 
$bin/mtxrun $bin/mtxrun.lua .
   $ ./context --nofile
   $ ./context --luatex --nofile
   
Running the above commands used to work with the old LuaTeX/kpse-based
wrapper, but it doesn't work any more. I was able to ""fix"" this by
adding the lines

   if os.selfpath then
   environment.ownbin = lfs.symlinktarget(os.selfpath .. io.fileseparator 
.. os.selfname)
   environment.ownpath = environment.ownbin:match("^.*" .. io.fileseparator)
   else
   environment.ownpath = kpse.new("luatex"):var_value("SELFAUTOLOC")
   environment.ownbin = environment.ownpath .. io.fileseparator .. (arg[-2] 
or arg[-1] or arg[0] or "luatex"):match("[^" .. io.fileseparator .. "]*$")
   end
   
to mtxrun.lua, right below the line

   package.loaded["data-ini"] = package.loaded["data-ini"] or true
   
but this is obviously not a very good fix.

There are some threads with more details at:

   https://tug.org/pipermail/tex-live/2023-March/049028.html
   https://gitlab.com/islandoftex/images/texlive/-/issues/30
   
Those links only discuss TL, but I get the same issue if I make a symlink
to the standalone ConTeXt files. 

Thanks,
-- Max

Re: [NTG-context] update

[Max Chernoff via ntg-context]

Hi Lynx,

> * How can I be sure that the standalone version is the one being
> implemented?

It depends on what your $PATH is set to. On Linux/macOS, you can run

   $ type -ap context

to list all the ConTeXts in your $PTAH. The first one in that list is
the one that will be ran by default.

If you want to always run the standalone version, then you'll need to
make sure that your ConTeXt directory comes before your TL directory in
your PATH. On Linux/macOS, you'd add something like

   export PATH="/path/to/context/bin/:$PATH"
   
to your ~/.profile; on Windows, you can use the "setx" command. Googling
something like "add location to path" will get you more specific
instructions for your OS/shell.

> * How do I update the standalone version

Just run the installer again. On my system, I run

   $ cd /opt/context
   $ sudo sh ./install.sh

> (I assume that, as of today,
> it is already the most up-to-date version

Correct.

> if and when it is
> required or desired to do so?

You only need to update ConTeXt if a new update fixes a bug that affects
you or adds a new feature that you want. Most updates are announced on
the list, so you could just update whenever you see a new update. Or you
could just try updating once per week. You could also just never update.
Up to you.

The general recommendation is to save an old copy of the ConTeXt folder
before you update in case something breaks. I've never done this before
though since I can usually patch the bugs myself, and I can always fall
back on the version in TL if something is really broken.

[NTG-context] upload

[Hans Hagen via ntg-context]

Hi,

I uploaded the last of series 2.10.07 as prelude for bachotex. That one 
also can do this:


\newfloat \MyFloat
\MyFloat \pfsin \floatexpr 1.25 * \pfpi \relax
\the\MyFloat

\the \pfsin \floatexpr 1.25 * \pfpi \relax

The syntax is like \numexpr and \dimexpr but the \pfsin (and other 
functions) are (as usual with these things) not real primitives but 
(\untraced) luacalls.


Of course it is all still somewhat experimental but likely to stay ...

Re: [NTG-context] update

[Max Chernoff via ntg-context]

Hi Hans,

> I actually dont' know the rules for updating texlive but there are
> definitely updates.

The rules are:

 - Packages and formats are updated about 24 hours after a new version
   is uploaded to CTAN.
   
 - Binaries are only updated once-per-year.

But there are also some special cases:

 - The luatex binary will be updated shortly for "reasons" (details to 
   be made public later).
   
 - The luametatex binary is allowed to be updated whenever.

  https://tug.org/pipermail/tex-live/2023-March/049058.html

 - I have no idea how ConTeXt is added to TL, but it doesn't appear to 
   be through the usual automatic CTAN sync. 
   
> Basically tex live is the yearly snapshot.

Because you're allowed to update luametatex at will and luatex hardly
changes, you could update the ConTeXt in TL more than once per year.
There's no need for it to get as many updates as the standalone
distribution, but it would be nice to get an update every 3 months or
so. (I have no idea how much work this is for you+Mojca, so it's maybe
not worth the effort).

> But you can just install the lmtx installation alongside (it's small

Lynx, I'll second this recommendation. The standalone lmtx distribution
is updated weekly-ish, uses less than 400MB disk space when installed,
and coexists happily with TL. The only downside is that it doesn't have
a friendly installation GUI like TL does. Even then, I personally find
it easier to install than TL.

No. Usually, texlive updates context once a year.


This is correct in general, but this specific update *will* end up in
TL2023 due to the engine changes that Hans mentioned. It's not in TL
yet, but we're actively working on it, so it should show up within a
week or so (hopefully).
Correction: Luigi and I are still discussing how to make it work because 
there is some init order issue and we want to be sure that context (and 
its scripts) keep working. It would be sort of weird if context (where 
luatex originates) would stop working as expected. Keep in mind that 
luatex is also a lua engine. and I assume that the texlive team also has 
some tests to perform (apart from getting all platforms updated which 
for some is more work, like apple signing).


The issue (disabling socket by default) is not that pressing as socket 
has been with us for right fromn the start) and security wise there are 
plenty ways tex can mess up your system if someone wants.

Re: performing update(s)

New to conTeXt, have not performed a specific update prior to this.

My conTeXt installation is part of TeXlive-2023 (under Linux OS). Will 
the updates to ConTeXt be handled by tlmgr ?
Basically tex live is the yearly snapshot. I actually dont' know the 
rules for updating texlive but there are definitely updates. But as much 
relates there (like engines shared between macro packages) it can be 
that only macros get updated and not engines (also relates to multiple 
platforms) so fundamental changes to luatex as engine .. hard to predict.


But you can just install the lmtx installation alongside (it's small 
compared to tex live) and have the best of both worlds. The lmtx 
installation also has mkiv. It also comes with the fonts that match what 
we expect in context (as fonts get updated or changed).

This is correct in general, but this specific update *will* end up in
TL2023 due to the engine changes that Hans mentioned. It's not in TL
yet, but we're actively working on it, so it should show up within a
week or so (hopefully).

Re: [NTG-context] update

[Jairo A. del Rio via ntg-context]

This is weird, but documents compile just fine if I comment the following
line in node-pag.mkxl:

\registerctxlua{node-pag}{}

Maybe leftovers from some experiment here?

Best regards.

No. Usually, texlive updates context once a year.

Re: [NTG-context] Font error in PDF using ConTeXt and Kepler typeface

[Werner Schmidt via ntg-context]

Hi all,

thanks for your ideas!

Could figure out the following:
- font files are found in the correct path  and cached & loaded properly (no 
second copies, no name clashes) 
- issue occurs under Linux as well as Windows
- issue is related only to some particular font files of the font family (not 
all)

[NTG-context] update

[Hans Hagen via ntg-context]

Hi,

I uploaded a new version with some new features discussed at the end of 
this mail.


- A next version of luatex will break context (format making etc) but 
the change is unavoidable because of other macro package demands wrt 
security (context does that differently). The low level start up command
has been adapted so unless you update indepdently thinsg should work ok. 
 Of course this has no consequences for lmtx.


- I've done a bit of callback cleanup (like getting rid of some mkiv 
luatex left-overs). It should have no effect on regular usage.


- There again a few improvements wrt math (this time dealing with 
accents artifacts in some fonts). We check all the free math fonts for 
potential issues and then try to fix it (read: deal with it). It's a lot 
of work but we're getting there.


- A few reported buglets have been fixed.

- The biggest addition is however a new number model. In metapost one 
can now use 'posit' (positfun instance) as number mode which will use 
(currently 32 bit but at some point 64 bit) posit unums. It's also bit 
of a playground because 32 bit posits are not more accurate than 64 bit 
doubles. It anyhow exposed some potential issues that we'll look into.


- There's also a (again currently 32 bit) posit library at the Lua end 
as playground.


- However, 32 bit posits come in handy at the tex end because they pack 
better accuracy in 32 bits than floats and it makes it possible to have 
native floats, so we have:


\newfloat  (uses \floatdef, register like \dimendef is used in \newdimen)

\newposit  (uses \positdef, like \dimensiondef etc)

\floatexpr (like \numexpr)

\iffloat   (like \ifnum) (also \ifabsfloat and i'll add the others too)

Actually it adds an extra range of registers so it bumps memory usage a 
bit. I'm considering lowering the number of registers (currently 64K per 
category) because after all, if 64K is not enough then we can as well 
stick to 32K or 16K (for some even less). There's always Lua for 
unlimited storage of quantities.


So,

\newfloat\fooA

\scratchdimen=123.456pt\relax[\type{dim:} 
\the\scratchdimen==123.456pt]\par
\fooA=123.456\relax  [\type{pos:} \the\fooA 
==123.456]  \par
\fooA=\scratchdimen\relax[\type{pos:} \the\fooA 
==123.456]  \par
\scratchdimen=\fooA\relax[\type{dim:} 
\the\scratchdimen==123.456pt]\par
\scratchdimen\dimexpr\fooA+10pt\relax[\type{dim:} 
\the\scratchdimen==133.456pt]\par


produces

[dim: 123.456pt==123.456pt]
[pos: 123.45600128173828==123.456]
[pos: 123.45599365234375==123.456]
[dim: 123.456pt==123.456pt]
[dim: 133.456pt==133.456pt]

As you can see dimens will get mapped onto floats not as integers 
(scaled points) but in pt units. Counts stay numbers. I need to handle 
glue too (not yet done).


In the future I might use this for fractions but there might be some 
rough ends so for now it's experimental.


Hans

My guess is that you need:

[filtercommand={/context/openscad/openscad -o \externalfilteroutputfile\space 
--view axes,edges,scales --viewall}

this is because any macro \something gobbles the space after that.

Re: [NTG-context] Font error in PDF using ConTeXt and Kepler typeface

[Bruce Horrocks via ntg-context]

Another check you can do is to run

  $ mtxrun --script font --list --name '--pattern=*kepler*'

and see if the file for keplerstd-light is the one you are expecting and not a 
second copy somewhere that is upsetting things.

I agree that it makes most sense to keep examples and (font) setups in

Projects with several files, like modules, should have their own (git) 
repositories. (The scripts at modules.contextgarden.net can pull 
releases directly from a repository.)


I think it’s better to have (and manage) your own account somewhere and 
link to it from the wiki than to use the “official” account for stuff 
that is not part of ConTeXt proper.


My stuff is at https://codeberg.org/fiee/; some of that would also make

[NTG-context] Idea for a shared repository.

[Pawel Urbanski via ntg-context]

Dear Everyone,

We currently have the Context Garden site, wiki and htis list for 
documentation and resources.



There is a Github contextgarden organization that can host repositories.


What about creating a repository called: 'templates' or 'resources' - we 
can figure out the exact name later.



The idea behind it is to collect templates and examples that are 
scattered all over the web or in the list threads. The first example 
that comes to my mind is the type definition for a Roboto font I needed 
and other type scripts that can be useful for the community. Then there 
are templates for books, slides or documents. The Repository has a wiki 
where we could add some notes about more complex items.



It is not about duplicating the Context garden site but to collect code 
in a place where we could gradually fix possible errors or introduce 
improvements.



All the best,

Pawel

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.

I realise that I should have been talking about the space between local

I assume it is \setupnote (rather than \setupnotation, my earlier

footnotes which is currently too large. I have tried 
\setupnote[before={\blank[small]}, after={\blank[small]}]. It appears to 
be reducing the space before the entire block of local footnotes but not 
between the footnotes themselves, which is what I am trying to do.


Did you try "inbetween" or "distance"? (I’d assume the latter is for the 
distance between number and text, but inbetween is usually vertically.)


https://wiki.contextgarden.net/Command/setupnote

Am I correct in assuming that the \setupnote should influence my 
\placelocalfootnotes? Or is there something else I should do in the case 
of local footnotes as distinct from general footnotes (my document 
contains ONLY local footnotes, however).


I was wondering if \setupnote[localfootnote][…] makes sense, but I can’t 
find in the sources if local footnotes are setup differently from 
general one.

To force all characters from the range in the fallback font, "force=yes"

Hi Thomas,

[NTG-context] fallbacks

[Thomas A. Schmitz via ntg-context]

Hi all,

today, I was struggling with a fallback font I had defined, and I 
discovered that the key "check" doesn't work as I expected. Here's a 
small example:


\definefallbackfamily [presentation] [serif] [TeXGyreTermes] 
[range=0x2329-0x232A,check=yes]

\definefontfamily [presentation] [serif] [AntykwaTorunska]
\setupbodyfont [presentation,12pt]

\starttext

(〈P〉)

\stoptext

With this input, the two characters 〈 and 〉 are not typeset; in the log, 
I find


fonts   > checking > char 〈 (U+02329) in font 
'AntykwaTorunska-Regular' with id 1: missing
fonts   > checking > char 〉 (U+0232A) in font 
'AntykwaTorunska-Regular' with id 1: missing


If I have "check=no," the characters are taken from termes and replaced. 
I was under the impression that "check" should, well, check if the 
characters are not in the main font and fall back to the fallback font 
if they are not, but this doesn't appear to be the case. So what does 
"check" do? Or is this a bug?

Re: [NTG-context] Table of contents not appearing.

[Fabrice Couvreur via ntg-context]

An extra parenthesis in a section title seems to be the problem but I'm not
sure. I compiled the file line by line and it works now.
Thanks
Fabrice

[NTG-context] Font error in PDF using ConTeXt and Kepler typeface

[Werner Schmidt via ntg-context]

Hi all,

I'd like to use the commercial Adobe Kepler typeface (Kepler Std - version 
2.020) in conTeXt (v2023-04-15) as text (serif) font. Although the font files 
are loaded correctly (see log below), the generated PDF is unreadable (see 
attached image).

Notes:
 - Only serif font (keplerstd-light.otf) is not working. It's not embedded in 
the generated PDF.
 - italics and bold fonts are embedded and are rendered well
 - Can't provide font files because Kepler is a commercial typeface

Do you have any ideas how to debug this issue?

Thanks Werner

log file:

[NTG-context] missing xml call

[Hans van der Meer via ntg-context]

\xmlatt{}{} has a counterpart \xmlattribute{}{LPATH}{} where one can start the 
search for the attribute at LPATH.
for \xmlchainatt{}{} I am missing such a counterpart 
\xmlchainattribute{}{LPATH}{} where one can do the same.

The problem now is that \xmlchainatt{#1}{att} always finds attribute att when 
it is defined on the node itself.
But consider the case where att="true" exists with the intention to trigger a 
search higher up in the call chain for that same attribute att.
Of course \xmlattribute{#1}{..}{att} is not exactly the same as 
\xmlchainattribute{#1}{..}{att} would be .

yours sincerely
dr. Hans van der Meer

Re: [NTG-context] Non-standard font alternatives

[Pawel Urbanski via ntg-context]

I've found the following Github repository with the typscripts definitions:

https://github.com/r3n4ud/roboto-context


When I use this type-imp-roboto.mkiv file fonts are used and embedded 
when using Roboto in thes \setupbodyfont[].



When I use ebgaramond as the body font but use:

\switchtobodyfont[roboto,20pt] in the \setuphead[] call the font is not 
embedded and seems to be not used.



I am more optimistic but still confused what can be wrong.

No, it does not. I am attaching hte type file and the short test document.


Here are the links where one can download the fonts:

https://github.com/googlefonts/roboto/releases

https://fonts.google.com/specimen/Roboto+Slab

 I am wondering if 'hinted' or 'unhinted' release of Roboto found at 
Github matters.



Trust me, that your time ahd help if very much appriciated. I know how 
much time it may take to debug such issue - just for rewriting the files 
with small changes.

Hi Willi,

What fun! I think I found a couple math items to correct.

1) The second line of the tables at the top of page 2 should be:
1000' 100, 10, 1; 8000, 400, 20, 1

2) For the year conversion: 2023 = 5x20^2 + 1x20 + 3. (Your 0 should be my 1). 
This will give a three digit Kaktovik numeral. You have 4 digit Kaktovik 
numerals for 2023, with both a 0 and a 1.
je kunt direct dat nummer converteren maar blijkbaar gaf ik de verkeerde 
volgorde uit:


\useMPlibrary[kaktovik] % de officiele manier

\definefontfeature
  [default]
  [default]
  [metapost=kaktovik]

\setupbodyfont[dejavu]

\starttext
 2023 \kaktoviknumerals{5}\kaktoviknumerals{1}\kaktoviknumerals{3}

\kaktoviknumerals{2023} % deze split dus voor je, order fixed
