[NTG-context] Add arrow tips to axes in lmt_function

[Jairo A. del Rio]

Hi, list! I want to know how to add arrow tips for axes (x, y) to a
function. I did the following based on a luametafun example:

\starttext
\startMPcode{doublefun}
draw lmt_function
[
xmin=0, xmax=10,
xstep=.05,
ymin=-2, ymax=2,

code="1.5 * math.cosd(240 * math.sqrt(x))",

xlabels="no",ylabels="no",

sx=2mm, sy=4mm, linewidth=.025mm, offset=.1mm,]

xsized 8cm;
\stopMPcode
\stoptext

But I didn't find anywhere in manuals or the mailing list concerning
arrows, nor key-value pairs for lmt_function. Thank you in advance.

Best regards,

Jairo :)

Current state (v. 2020.09.18 20:32):

Some progress: Footnotes are still as wide as the image they belong to (in both 
versions), but in LMTX some footnotes are missing.

Most likely due to my limited understanding of how these things work. 
I thought storing the text and retrieving it later would be the 
easiest way to get rid of the constraints of linar processing of the 
XML file. The layout itself is determined by setups such as this one:


there is no linear processing, you just start someplace and 
recursively deal with the tree (which often looks like linear when you 
start at the root but basically you can access everything everywhere)



\startsetups abstract
 \startabstract
     \documentvariable{abstract}
 \stopabstract
\stopsetups

\setuphead [chapter][
 alternative=middle,
 page=yes,
 indentnext=no,
 style=\tfa\setupinterlinespace,
 after={\directsetup{placeauthors}\directsetup{abstract}},
 footer=chapterfooter,
 ]

How could I fetch the xml node from here so I don't need a variable, 
buffer or the like?

just pass the root element i.e. instead of #1 in

 \xmlfilter{#1}{/abstract/command(xml:article-meta:abstract)}

as #1 is just an abstraction for the current element; you pass the 
name you used when loading the tree (often \xmldocument works too)




Thanks. That is very helpful. And indeed, that makes things much easier!

Thanks. I'll need to check what happens here.

Hi

Is there a setting that prevents footnotes from spreading over more than
one page? I have a document where this seems to be the case, but I don't
know why. It just looks like ConTeXt tries to keep the complete footnote
on one page, which leads to ugly white space at the end of almost every
page. (LaTeX has \interfootnotelinepenalty to customize this, but what
about ConTeXt?)

split=strict|verystrict|tolerant

we're tolerant by default

Dingbats are old school t1 without proper names so we can't use
unicodes. However, there is a goodie that should do that so that in
principle it should work with unicodes but there is some interference
going on (i'll look at that)

For nwo access by 'name' or 'index' (these are kind of stable for such
an old font):

       n:a34  : \getglyph{ZapfDingbats}{\tochar{n:a34}}  \par
       n:a35  : \getglyph{ZapfDingbats}{\tochar{n:a35}}  \par
       i:48   : \getglyph{ZapfDingbats}{\tochar{i:48}}   \par
       i:49   : \getglyph{ZapfDingbats}{\tochar{i:49}}   \par
       n:a104 : \getglyph{ZapfDingbats}{\tochar{n:a104}} \par
       n:a105 : \getglyph{ZapfDingbats}{\tochar{n:a105}} \par

Thank you Hans!
Access by glyph index with \tochar{i:19} works well for both MKIV and 
LMTX. Access by name with \tochar{n:a39} does not work in LMTX with log 
message: char ✓ (U+02713) in font 'ZapfDingbats-4' with id 8: missing. 
Also \ShowCompleteFont does not report any glyph names in LMTX.
should be a bit better in yesterdays upload (i also changed the file 
name alias so that in pinciple unicode should work too)
