I have only tested it with TeXLive. But if lmtx provides a lua 
interpreter with kpathsea bindings, like the usual texlua, then it will 
surely work. If that's not the case and you installed lmtx in a 
nonstandard location, you will need to set an environment variable to 
specify the location of the interface XML files.

you can use resolvers.findfile when you use

It's nice to see a new third party module for ConTeXt but you have to
make a few changes.

1. You have to put the module and the documentation in the correct doc
and tex folders.


I'm doing it now. Thanks, I'll give my module some more order.

2. You should give your manual a better name, e.g. metaducks-manual.tex 



Agreed. I'll prepare a better manual before updating.

3. You can put your color definitions in the module, there is no need
for a new color file, especially because most of the colors you use are
already predefined.


Oh, colors are a bit different, so I copied RGB definitions from 
xcolor.sty, especially because with ConTeXt colors ducks looked a bit 
"brown" rather than yellow. However, I can merge t-metaducks.mkvi and 
colo-imp-xcolor.mkiv if necessary.

no need to merge ... in lmtx you can play with

withcolor "red"

and such ... best keep colors abstract

My problem is not to make the arrow bigger, I actually want to make it smaller.
I have 2 long words above it, and so it's really long. I could use \clap{}, but
then the spacing is gone and my 2 words clash with the text left and right of
the arrow. So I want a small arrow with long text above it, but the spacing
should be oriented on the text.

Thanks a lot for your work on digestif and improving ConTeX support!

I'd probably like to use it with SublimeText which I favour over VScode...

I'd have to revive ST's package which provides support for ConTeXt syntax and
now trying it with vim/coc, but wonder whether you're using TeXLive or lmtx? 

I'm trying with the latter on Debian (Sid)...

I'm not sure which manual you are looking in to find a reference to the ability 
to add a specific dimension.

In the source I can only find named sizes of 'none', 'normal', 'small', 
'medium' and 'big'. You can 'kludge' these by extending the length of the text 
using hard spaces. Alternatively there is \rightarrowfill which you might be

I don’t know if that helps, but I’m using a stack of transparent objects to 
simulate drop shadows:
https://wiki.contextgarden.net/Drop_shadows

No pixel images required. But I’d like to have a real text shadow instead of 
that box shadow.

[NTG-context] SILE typesetter and other projects

[denis.maier]

Hi
I just came across the SILE typesetter (https://sile-typesetter.org), which 
looks quite interesting and somehow similar to ConTeXt in some ways (e.g. lua), 
apart from the fact that it does not use TeX at all. ;-) Another project seems 
to be Patoline. Just out of curiosity: Has anyone some experience with these 
tools?
Best
Denis
