Thanks Hans,
this solves the problem I had with the new implementation of \wordright.
It's not exactly a problem of \wordright, but the combination with
\groupedcommand.
that is always tricky as what happens is postponing till the group ends
but wordright now kind of hooks into the par construction
Is \nextbox a new entry of latest versions?
no, actually one of the oldest things
I've seen also \nextboxwd, \nextboxht, etc.
So you can measure the next box to come in advance. Is it like that?
Is it a vbox when you're in vertical mode and a hbox when you are in
horizontal mode?
you just pass the box
Is this interpretation of \dowithnextbox in \dowhatever right?
\dowithnextbox {.1.} \.2. {.3.}
1 COMMAND = {\ifdim\wd\nextbox<\hsize...}
2 CSNAME = \hbox or \vbox
3 CONTENT = {#1}
yes

\type{\wordorparagraphright} should use \type{\wordright} if its
argument
is narrower than \type{\hsize}, or make a right-aligned paragraph
with it
when it's wider.
Below, \type{\wordorparagraphright} is tested with a short text, that
has enough room on the same line.

Reference:
\input ward\wordright{same line, right}

Implementation as a grouped command (it doesn't work):
\input ward\groupedwordorparagraphright{same line, right}

Normal implementation, not as a grouped command (it works):
\input ward\wordorparagraphright{same line, right}
\stoptext
Unfortunately the grouped version is the one I need, because it's used
in a register, and it would give an error if not defined through
\groupedcommand:
\setupregister[myregister]
[pageleft=\wordorparagraphright\bgroup,pageright=\egroup]

[NTG-context] strange behavior with \groupedcommand in recent versions of LMTX
Hello list,
this is a MWE that worked right in MkIV and in LMTX versions (at least)
until April 22nd, 2020.
There's a macro, \wordorparagraphright, that takes one argument, makes a
hbox with it and measures its width
- if its width is less than \hsize, then it calls \wordright
- if its width is more than \hsize, then it ends the current paragraph
and starts a right-aligned paragraph with the argument
There are two implementations in the MWE: one is through
\groupedcommand, and that's the one that worked once and doesn't now.
\unexpanded\def\groupedwordorparagraphright{\dosingleempty\dogroupedwordorparagraphright}
\def\dogroupedwordorparagraphright[#1]{\groupedcommand{\setbox\scratchbox\hbox\bgroup}
{\egroup\ifdim\wd\scratchbox < \hsize
\wordright{\unhbox\scratchbox}
\else
\par\penalty1
\startalignment[flushright]\unhbox\scratchbox\stopalignment
\fi}}
\unexpanded\def\wordorparagraphright#1{%
\setbox\scratchbox\hbox{#1}
\ifdim\wd\scratchbox < \hsize
\wordright{#1}
\else
\par\penalty1
\startalignment[flushright]\unhbox\scratchbox\stopalignment
\fi}
\starttext
