See https://mailman.ntg.nl/pipermail/ntg-context/2016/084858.html - case (2) I am afraid I hasn't been clear enough yet. > > 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 > So the following \parfillskip specification finally seems to be what I was looking for as it covers both cases in my original question: \setupindenting[yes,2em] \newdimen\lastlineminlength \newdimen\lastlinemingap \lastlineminlength=3em \lastlinemingap=1em \parfillskip \lastlinemingap plus \dimexpr\availablehsize-\lastlineminlength-\lastlinemingap\relax \edef\ward{\cldloadfile{ward}} \starttext \dorecurse{100}{ \hsize\dimexpr\textwidth-#1mm\relax \ward \par \ward \par \startnarrower[left] \ward \par \ward \par \stopnarrower \page } \stoptext As it can be done in one place globally and in almost single line, no special new command is necessary (as requested originally).
