[NTG-context] Calling \followtokens from with in metapost
Hello list, How can I call the \followtokens macro (or a similar solution) from within metapost? Specifically, I want to integrate text between the semi-circle arcs in a rainbow-like structure (with the text placed inbetween the arcs, that should alsó be drawn). The text should not be stretched but center on the top, flowing evenly distributed on each side. This link will give you an idea: http://www.heilsuefling.is/heilsuefling/upload/images/whp_in_general/determinants_of_health/determinants_of_health.jpg How can this achieved?

I understand the priorities of the team, that is why I think that offloading font support is beneficial to everyone. break in what sense? what features (just curious) ... anyway, The mark filtering sets we discussed few years ago, for instance; I had to redo the whole font in a much more complex way with few more thousands of glyphs to avoid using them so the font remains usable with ConTeXt, and I still get crashes every now and then that I stopped bothering with reporting

Hi all,
\definefallbackfamily [mainface] [serif] [DejaVu Serif]
[range=cyrillic,force=yes]
What if I want to use the CJK font? The code in font-sel.mkvi hints
I could use range=chinese but it didn't work. I have to use interval
{0x00400-0x2FA1F} explicitly.
When you take a look into char-def.lua you can see names certain
character ranges and “range=cyrillic”
used such a name.
For a chinese font you need
“range={cjkunifiedideographs,cjkunifiedideographsextensiona,…}.
Because the list with names is very long you do this setup only once
with the \definefontfamilypreset
command, e.g.
\definefontfamilypreset[chinese][range={cjkunifiedideographs,cjkunifiedideographsextensiona,…}]
and load this setup when you set the font with
\definefontfamilyfallback, e.g.
\definefontfamilyfallback[typeface][style][font][preset=chinese]
For the moment I added three presets “chinese”, “japanese” and
“korean” but they need better
names, e.g. “range:chinese” because there could be also
“features:chinese” etc.
I get it now. I can put range and features of the fallback fonts in the
preset.
And how can I assign the boldfont, italicfont and bolditalicfont? I'm
currently using the Adobe Song Std as the regular font but it didn't
come with a bold version or else, hence I might need this feature.
The module provides keys to apply a certain font and feature for each
alternative (upright, italic etc.)
of a font, a complete list with all keys is shown in the table below.
---
| Alternative | Font| Feature |
|-|
| tf | regularfont | regularfeatures |
| it | italicfont | italicfeatures |
| sl | slantedfont | slantedfeatures |
| bf | boldfont| boldfeatures|
| bi | bolditalicfont | bolditalicfeatures |
| bs | boldslantedfont | boldslantedfeatures |
| sc | smallcapsfont | smallcapsfeatures |
---
The feature-keys expect the name from the \definefontfeature command,
when you don’t
specify a feature to a certain alternative the value from the
“features” key is used.
When you want to set a certain font for a alternative there are
different ways, I’m going
to show the different ways with a few examples where I change the font
for italic.
Thanks for the descriptions. I have made a small test and turns out the
regularfont has to be assigned to something or the other xxxfonts
won't have any effects.
Here's my code:
=
\definefallbackfamily [mainface] [serif] [adobesongstd]
[range={0x00400-0x2FA1F}%
,regularfont=name:adobesongstdlight%
,italicfont=name:adobefangsongstdregular%
,boldfont=name:adobeheitistdregular%
,bolditalicfont=name:adobekaitistdregular%
,force=yes%
,features=song%
]
=
and if I remove the regularfont=... line, the boldface Chinese
characters will use the Adobe Song Std font as well. Same thing happened
when I used the preset=xxx option which I don't know if it is intended
to behave like that, by the way.
Oh, and off the topic, can I use effect to assign the fonts? Like if I
have defined
=
\defineeffect[mybold][alternative=both,rulethickness=\dimexpr\bodyfontsize/10\relax]
=
I would like to use this effect to apply to my bold fonts, maybe:
=
\setupfontfamily [serif] [DejaVu Serif] [boldfont=effect:mybold]
=
I know this has nothing to do with this module. I just thought this
might be interesting.
1. Use the filename of a font. With the “file:” prefix you can the
tell the module
to look for a file with the given name, when the file isn’t found the
font from
the tf-alternative is used. The file-method is also used when you omit
the prefix.
\setupfontfamily [serif] [DejaVu Serif] [italicfont=file:dejavuserifbold]
\starttext
Regular and \it Italic
\stoptext
2. Use a certain style. When you use the “style: ”prefix the module
looks for a certain
style of the requested font.
\setupfontfamily [serif] [DejaVu Serif] [italicfont=style:bolditalic]
\starttext
Regular and \it Italic
\stoptext
3. Search for a font with a certain name. When you use the “name:”
prefix the module
looks for a font with the requested name. Names are internal values of
a font

That’s not possible but you can the slant and extend options from

[NTG-context] list of useful typescripts.
I am seeking to create (or download) a list of useful typescripts. I define useful as those which call upon fonts/typefaces that are actually distributed with texlive. Perhaps this list exists somewhere. If so I would appreciate a pointer. A list of typescripts that is limited to those calling on fonts in the context distribution would be useful if the list described above is not available. Ultimately I wish to winnow down the list to those fonts containing serif typefaces suitable for use in the text of a novel. The font should have at a minimum roman, italic, bold, bold-italic and small caps typefaces. I can if necessary develop this list myself. But I have learned that is better to ask than to reinvent the wheel. All replies appreciated.

[NTG-context] broken Czech dates
Hello,
the current ConTeXt Standalone contains a bug when attempting to output
Czech dates.
Minimal example:
\mainlanguage[cs]
\starttext
\currentdate
\stoptext
Expected output:
13. řijna 2013
Received output:
day, ,month, ,year
The culprit appears to be a missing comma in the language definition in
lang-def.mkiv:
\installlanguage
[\s!cs]
[ % ...
\c!rightquotation=\upperrightdoublesixquote,
\c!date={\v!day,\fourperemspace,\v!month,\space,\v!year}
\s!lefthyphenmin=2,
% ...
]
Add a comma at the end of the line defining the date format; this appears
to fix the problem.
As far as I can tell, the definitions of Slovak (sk) and Turkmen (tk)
appear to be suffering from the same problem.

How about switching paired boxes to \assumelongusagecs as well and
getting rid of \dogotopar? Paired boxes are the only mechanism which
uses \dogotopar.

This stretches the text. One has to use \hskip to squeeze the text
back to its normal inter character space, but I assume that's what
you meant by clumsy. I assume the OP wanted a solution which keeps
the natural spacing (whatever that means when text is aligned to a
path).

I'm trying to use Lua with ConTeXt as a macro preprocessor. To be more
clear, I have files A.lua, B.lua which define some variables:
A.lua:
var1 = something for a
var2 = something else for a
B.lua:
var1 = something for b
var2 = something else for b
And, in my ConTeXt file, I would write:

I will get \directlua{tex.print(var1) and \directlua{tex.print(var2)}.

Now, with lualatex, I use the --lua command line option to pass the
initial lua file name. However, for context, I've not found a way to
do this. Could someone please advise me?
