We basically need: <text><glue min-width='XX' max-width='hsize-3*indent'>

and I thought this is exactly what \parfillskip ensures \parfillskip XX plus (hsize - 3*indent)

the fil is taken into account when calculating the best break points and then the XX is fixed but plus/minus can lead to if being less or more, all relative to other fill (distributed)

so, XX plus (hsize - 3*indent) is not a fixed value, it's XX or more

take this:

\ruledhbox to 10cm {x\hskip0pt plus 1cm x}

the skip will stretch more than 1cm

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

there is but not enough stretch so there will be a warning ... you can see it from \ruledhbox to 10cm {x} \ruledhbox to 10cm {x\hskip0pt plus 1cm} \ruledhbox to 10cm {x\hskip0pt plus 1fill}

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.

you always add a 2em skip so there will never be a word touching the right margin in the last line; furthermore you permit some stretch, but as said before this stretch is not frozen, it's a ratio relative to other stretch \ruledhbox to 10cm {x\hskip2em plus 1cm x\hskip2em plus 1cm x} so, the plus 1cm can become more than that depending on needs (onlky the warning is influenced

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

\availablehsize i think that the #1 gap is irrelevant and actually makes it worse as it add space while you actually want it to move the other direction anyway, this is why using a couple of non-hyphenated words or a minimum amount of characters makes more sense ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
