Dear Hans,
Thank you for a solution.
In my memory, it is possible to check the argument in Lua, so I hope
that there is a similar method in MetaFun.
It may be easier to draw grid using lines instead of squares.
vardef textlength(text t) =
save n ; n := 0 ;
for i = t :
n := n + 1 ;
endfor;
n
enddef;
def drawGridF (expr nb) (text s) =
if textlength(s) = 0 :
draw textext("A grid!");
else :
path p ;
picture pic ;
numeric n;
p := unitsquare scaled wu;
n:= 0;
for m = s:
i:= n mod nb;
j:= n div nb;
pic := image (draw p; label(textext(m), center p); );
draw pic shifted (i*wu, j*wu);
n:= n+ 1;
endfor;
fi ;
enddef;
Thank you again.

Dear all,
In the following sample, it draws squares with label which is given.
I’d like to know how to check the number of elements in the second

If it is 0, then I just draw grids only.

[NTG-context] How to adjust inter item vertical space
I want to fit a page with an itemized group of items. The normal vertical spacing is to large and the [packed] doesn't give enough seperation between items. I should think that there's a simple way to adjust this with \setupitemize command or even with \startitemize. Is there? I did try \setupitemize[inbetween=\whitespace[medium]] , but it didn't do much or seemed to be applied to every line and not just between item and 'medium' doesn't give much information.

Re: [NTG-context] How to adjust inter item vertical space
Hi,
You can define your own white space and then attribute it to each item, as in
the following:
\setupwhitespace[big]
\startsetups[mywhitespace]
\setupwhitespace[small]
\setupblank[small]
\stopsetups
\setupitemize[each][inner=\directsetup{mywhitespace}]
\starttext
\input knuth
\startitemize
\dorecurse{3}{%
\startitem
\input ward
\stopitem}
\stopitemize
\stoptext

[NTG-context] \startcolumns and multi-line footnotes

With the new version of columns, how do I get multi-line footnotes?
I tried various things with \setupnotation but nothing seems to work?

\startcolumns
\dorecurse{3}{\input ward\footnote{\input zapf} }
\stopcolumns

If the text has constant interline spacing, you can try to mimick the old
(mkii) underbar mechanism. See https://tex.stackexchange.com/a/125486/323
for an example. I haven't tested this with nested backgrounds, but it
should work.

Re: [NTG-context] \startcolumns and multi-line footnotes
Hi Taco,
There two documents

and
/context-minimal/tex/texmf-context/doc/context/documents/general/manuals/pagecolumns.pdf
written by Hans in which he says that long footnotes and columns cannot be
treated correctly yet (in the first one) and in the second he says that
pagecolumns can handle a « sane » usage of columns and footnotes…
Indeed the following works but not with your example :-(

It worked ok for decades, in fact. The weird bit here is that the new mixed columns do actually reserve the correct amount of vertical space for the footnote, they just seem to ‘forget’ to break the footnote into lines in the end.

[NTG-context] Scaling down symbols and emojis
I'm having trouble scaling down symbols and emojis. For a while I assumed
these don't scale with the current font size. Then I scoured the mailing
list and realized that while scaling down seems broken, scaling up works as
expected:
\usesymbols[mvs]
\setupsymbolset[martinvogel 2]
%\showallmakeup
\starttext
% Progressively larger as expected.
\symbol[ShortForty]
{\tfa\symbol[ShortForty]}
{\tfb\symbol[ShortForty]}
{\tfc\symbol[ShortForty]}
{\tfd\symbol[ShortForty]}
% Unexpectedly all the same size.
\symbol[ShortForty]
{\tfx\symbol[ShortForty]}
{\tfxx\symbol[ShortForty]}
% This works, but why? Isn't \small just a synonym for \tfx via
% \definealternativestyle? Anyway there is no synonym for \tfxx.
\symbol[ShortForty]
{\switchtobodyfont[small]\symbol[ShortForty]}
{\small\symbol[ShortForty]}
% This also works but is less than ideal when matching surrounding font
sizes.
% Which factor should I use to match \tfxx?
\symbol[ShortForty]
\scale[factor=4]{\symbol[ShortForty]}
% Same as above comment, more or less.
\symbol[ShortForty]
{\switchtobodyfont[5pt]\symbol[ShortForty]}
\stoptext
* MWE for builtin symbols; emojis require local fonts. I assume whichever
solution would apply equally to either.

When you need a switch for a smaller size which doesn’t has these

In case the current bodyfontenvironment overrides the smaller sizes is
it possible to define 'n' and 'm' in terms of 'x' and 'xx'?
% this should happen after \setupbodyfont so the correct values are fetched
\setupbodyfontenvironment
[default]
[m=\getcurrentbodyfontenvironment{x},
n=\getcurrentbodyfontenvironment{xx}]

Or I use {\switchtobodyfont[...]\symbol[ShortForty]} in the document.
At that point the body font may have been switched to a size whose
environment defines different values for 'x' and 'xx'. Or perhaps the
current or default body font, via \definebodyfont, overrides the 'x'
and 'xx' sizes. In either case it would be more flexible to query the
current values of 'x' and 'xx' rather than hardcoding the values of
'n' and 'm'. Is something like this possible:
% provide size name ('xx', 'x', 'a', 'b', 'c', 'd') and contents
\define[2]\at_size_unrestricted{\switchtobodyfont[\getcurrentsize[#1]]#2}
