I can see.
But sorry for my ignorance, as far as I understand, \parfillskip is added to
the end of the paragraph, so we have rather
\ruledhbox to 10cm {x\hskip0pt plus 1cm} % without that 'x' at the end, so no
'glue' distribution is performed
If '\parfillskip 2em plus (hsize - 3*(2em) - 2em)' is specified, I still think
we should get space of width at least 2em '####' which can be extended as
indicated by hyphens '-' here:
emememememememememememememememememememem
emememememem------------------------####
So there are two last line lengths extrems:
(shortest)
emememememememememememememememememememem
emememememem
(longest)
emememememememememememememememememememem
emememememememememememememememememem
I slightly modified your example and even with verystrict settings all seems to
be fine (except too narrow blocks, which is not my use case).
\showmakeup[glue]
\setupindenting[yes,2em]
\edef\ward{\cldloadfile{ward}}
\setupalign[verystrict,hz]
\starttext
\dorecurse{100}{
\hsize\dimexpr\textwidth-#1mm\relax
\dimen0=\hsize
\advance\dimen0 by -8em % 3*em - 2em
\parfillskip 2em plus \dimen0\relax
\ward \par
\parfillskip 2em plus \dimen0\relax
\ward \par
\startnarrower[left]
\parfillskip 2em plus \dimen0\relax
\ward \par
\stopnarrower
\startnarrower[left]
\parfillskip 2em plus \dimen0\relax
\ward \par
\stopnarrower
\page
}
\stoptext
The problem here this settings cannot be done globally if there are various
block widths.
Can I somehow define command globally which takes local block widths?
\parfillskip #1 plus \localhsize-#1-#2, where
#1 gap width
#2 shortest line width
