Hi,
there was a question on the Stackexchange site [*] with a problem for the \starthanging environment when the alignment is R2L.
\def\spac_hanging_finish {\scratchdistance\directhangingparameter\c!distance\relax \ifdim\ht\nextbox>\strutht \setbox\nextbox\tbox{\box\nextbox}% \fi \scratchcounter\directhangingparameter\c!n\relax \ifnum\scratchcounter>\zerocount \hangafter-\scratchcounter \else \getboxheight\scratchdimen\of\box\nextbox \getnoflines\scratchdimen \hangafter-\noflines \fi \ht\nextbox\strutht \dp\nextbox\strutdp \scratchwidth\dimexpr\wd\nextbox+\scratchdistance\relax \ifx\m_spac_hanging_location\v!right \hangindent\ifconditional\displaylefttoright-\fi\scratchwidth \rlap{\hskip\dimexpr\hsize-\wd\nextbox\relax\box\nextbox}% \else \hangindent\ifconditional\displaylefttoright\else-\fi\scratchwidth \llap{\box\nextbox\hskip\scratchdistance}% \fi \ignorespaces} (maybe the content of the hang blob will becoem l2r)
Here is shortened version of the example:
%%%% begin example \useMPlibrary[dum]
\starttext
\starthanging[location=left]{\externalfigure[dummy][width=4cm,height=3\lineheight]}
\input tufte \stophanging
\blank
\startalignment[righttoleft] \starthanging[location=left]{\externalfigure[dummy][width=4cm,height=3\lineheight]}
\input tufte \stophanging \stopalignment
\stoptext %%%% end example
The problem is that \hangindent behaves the same for L2R and R2L alignment unlike the other formatting commands (\hangindent or \leftskip) for paragraphs.
%%%% begin example \showframe[text][text]
\setuphead [subject] [align=lefttoright, indentnext=yes]
\starttext
\startbuffer
\subject{Normal paragraph}
\input ward
\subject{Leftskip}
\start \leftskip 4em \input ward\par \stop
\subject{Parindent}
\start
\parindent 4em \input ward\par
\stop
\subject{Hangindent}
\start \hangindent 4em \hangafter -2 \input ward\par \stop
\stopbuffer
\title{Left to right}
\startalignment[lefttoright] \getbuffer \stopalignment
\title{Right to left}
\startalignment[righttoleft] \getbuffer \stopalignment
\stoptext %%%% end example
