Hi Hans,
Thank you for the new upload.
The teaser examples work fine, many thanks ! I have a question though: how can one center within a page a text, for example typeset in a circular shape? I tried with \startalignment, and also with \startplacefigure but none of these gives a centered circular shape.
Also I noticed that if one removes the comment at the end of \startshapedparagraph, or add a blank line after that, then the circular shape is destroyed: is this on purpose ? \starttext
\startuseMPgraphic{circleBis} lmt_parshape [ path = fullcircle scaled 90mm, offset = 2mm, bottomskip = - 1.5LineHeight, ] ; \stopuseMPgraphic \startplacefigure[align=middle,number=no] \framed[width=90mm,offset=2mm,align=normal]\bgroup \startshapedparagraph [list=circle,mp=circleBis,repeat=yes,method=repeat]% \setupalign[verytolerant,stretch,last]\dontcomplain {\darkred \samplefile{thuan}} \stopshapedparagraph \egroup \stopplacefigure \stoptext We're talking parshapes here, think of \parshape 2 2mm 10cm 4mm 12cm or \parshape 2 options 1 % force a repeat 2mm 10cm 4mm 12cm but then nicely wrapped in a macro. The circle is (cf metafun manual) converted into such a parshape. A parshape is forgotten when a new paragraph is started, but ... we have extra magic that revives them which is why the multi-page-par examples work too. The cycle and repeat methods do that (using abit diufferent tricks than the 20 year old one but not that different); these methods are independent of the parshape's repeat option itself, which is an engine feature. Messing with left/right 'align' will also bring left/rightskip into the game so normally you will not do that. I admit it take a bit of imagination to get the picture. The 'last' keyword is some old context feature that centers the last line (which looks nicer in a circle) which is using some parfillskip magic.
