Yes, something has changed internally. Earlier, if you used:
\startalign[align={right,left}, n=4]
...
\stopalign
then the alignment was right left right left, i.e., the alignment cycled. Now,
the alignment is right left left left, i.e., unspecified alignments default to
left. So, in your example, each column in the second "block" is left aligned.
To change that, you can use:
\starttext
\startformula \startalign[m=2,distance=8em,n=5,
align={right,middle,middle,middle,left, right,middle,middle,middle,left}]
\NC 0 \NC < \NC 2x + 5y \NC < \NC 10
\NC 4 \NC < \NC 3x + y \NC < \NC 9 \NR
\NC 3 \NC < \NC 2y + 3z \NC < \NC 15
\NC 10\NC < \NC 8y + 5z \NC < \NC 20 \NR
\stopalign \stopformula
\stoptext
But this is ugly.
I haven't looked at the math alignment code in a while, but I'll check with
Hans if the old behavior can be reintroduced.

There was a drops module by Peter Rolf, which provides exactly these features:
https://mailman.ntg.nl/pipermail/ntg-context/2016/084242.html
It is not part of modules.contextgarden.net and the url in the previous post is
no longer valid.
I am CC:ing Peter and perhaps he can point to the updated location for the
module.

You can try: context --nodummy filename which will not generate the "error" pdf. However, if the error was such that context had to abort the run, then no valid PDF will be generated. You cannot have the previous PDF untouched because context starts overwriting the PDF while processing. Another option is to use context --result=output.pdf filename in which case context writes the result to output.pdf. If there is an error, then output.pdf is not overwritten. Depending on your pdf viewer, this might work better.

The syntax is:

Do you mean \mathclap? If so, then in Context, \clap works correctly in both
text and math mode. So, you can just use:
\starttext
$4 \underbrace{+ 3}_{\clap{\text{because of lorem} + 2}}$
\stoptext

Feedback is welcome. this looks great. Thanks a lot for this. Unfortunately I get Company mode enabled in current buffer Yas minor mode enabled in current buffer eglot--connect: Symbol’s function definition is void: project-root when I activate eglot in emacs. Using (require 'company-lsp) (add-to-list 'company-lsp-filter-candidates '(digestif . nil)) Using lsp-mode I get progn: Symbol’s value as variable is void: company-lsp-filter-candidates for (add-to-list 'company-lsp-filter-candidates '(digestif . nil)) I have no experience with using either eglot or lsp-mode.

Re: [NTG-context] Ducks in ConTeXt
Jairo A. del Rio schrieb am 24.12.2020 um 15:18:
Hi everyone!
I've recently ported TikZducks to ConTeXt and finally removed TIkZ
along the way. So a new module was created. The module is called
"metaducks" (lol) and it's essentially a \useMPgraphic{...} with a lot
of options, most of them ported from TikZducks. For those not familiar
with the package, it draws customized rubber ducks :) I want to
include some more, so I'll gladly read any feedback, recommendations
and suggestions. Eventually I want it to be a module on its own. The
module is already in the ConTeXt Group:
https://modules.contextgarden.net/cgi-bin/module.cgi/action=details/id=105
in case anyone wants to give it a try. Here's a minimal example:
\usemodule[metaducks]
\starttext
\ducks[santa=true,mug=true]
\stoptext
I wish the best for you all. Happy holidays!
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.
2. You should give your manual a better name, e.g. metaducks-manual.tex
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.

[NTG-context] Text editor support via Digestif
Hi all, I have worked a bit on ConTeXt support in the Digestif language server [1], and I think it's pretty usable by this point, so I would like to invite everyone to check it out. Feedback is welcome. Digestif plugs into any editor that support the Language Server Protocol, and provides the usual IDE features: completion (of commands, keyword arguments, references, citations), go to definition, find references, document outline, etc. Among the fancier features is fuzzy-matching, so you can, say, find a citation by typing parts of the title or author names (and get away with using meaningless BibTeX identifiers). The newest (git) version reads the ConTeXt interface files at runtime, so it should be pretty accurate, and also work with third-party packages. It would be cool to also have some integrated documentation, but it looks like ConTeXt (or TeX in general) doesn't have anything of help in this direction currently, right? Another nice thing is that Digestif is a Lua program, and can run on the LuaTeX interpreter with no extra dependencies. On the other hand, I didn't get the change to test it on Windows or editors other than Emacs, although both things should work with minimal adjustments. Let me know if you have any issues.
