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 ? Best regards: Otared % begin example-circular-shape.tex \starttext %\startuseMPgraphic{circle} % lmt_parshape [ % path = fullcircle scaled 136mm, % offset = 2mm, % bottomskip = - 1.5LineHeight, % ] ; %\stopuseMPgraphic \startuseMPgraphic{circleBis} lmt_parshape [ path = fullcircle scaled 90mm, offset = 2mm, bottomskip = - 1.5LineHeight, ] ; \stopuseMPgraphic \startalignment[middle] %\startplacefigure[align=middle,number=no] \start \startshapedparagraph[list=circle,mp=circleBis,repeat=yes,method=repeat]% \setupalign[verytolerant,stretch,last] \dontcomplain {\darkred \samplefile{thuan}} \stopshapedparagraph \stop %\stopplacefigure \stopalignment \stoptext % end example-circular-shape.tex

Hi,

I uploaded a new lmtx. As I'm currently going through the metafun todo files I ended up at the fancy shape part (parshapes) running over multiple paragraphs and decided to provide a (kind of low level) interface that integrates that. The example code is a few decades old but still works ok (i might try to improve them a bit some day). Anyway, here is a teaser:

\starttext

\startuseMPgraphic{circle} lmt_parshape [ path = fullcircle scaled 136mm, offset = 2mm, bottomskip = - 1.5LineHeight, ] ; \stopuseMPgraphic

\start \startshapedparagraph[list=circle,mp=circle,repeat=yes,method=cycle]% \setupalign[verytolerant,stretch,last]\dontcomplain {\darkred \samplefile{tufte}}\par {\darkgreen \samplefile{tufte}}\par {\darkblue \samplefile{tufte}}\par {\darkcyan \samplefile{tufte}}\par {\darkmagenta \samplefile{tufte}}\par \stopshapedparagraph \stop

\page

\start \startshapedparagraph[list=circle,mp=circle,repeat=yes,method=repeat]% \setupalign[verytolerant,stretch,last]\dontcomplain {\darkred \samplefile{tufte}} {\darkgreen \samplefile{tufte}} {\darkblue \samplefile{tufte}} {\darkcyan \samplefile{tufte}} {\darkmagenta \samplefile{tufte}} \stopshapedparagraph \stop

\stoptext

The interface is still somewhat rough (no grouping for instance, not a real envrionment so that might change) but seems to work ok. One can also go the tex route and say:

\startparagraphshape[test] left 1mm right 1mm left 2mm right 2mm left 3mm right 3mm copy 8 left 4mm right 4mm left 5mm right 5mm left 5mm hsize 10cm \stopparagraphshape

or

\startparagraphshape[test] left 1mm right 1mm right 3mm left 5mm right 5mm repeat \stopparagraphshape

or

\startparagraphshape[test] both 1mm both 2mm both 3mm both 4mm both 5mm both 6mm both 7mm both 6mm both 5mm both 4mm both 3mm both 2mm \stopparagraphshape

or

\startparagraphshape[test-repeat] both 1mm both 2mm both 3mm both 4mm both 5mm both 6mm both 7mm both 6mm both 5mm both 4mm both 3mm both 2mm repeat \stopparagraphshape

and use that with:

\startshapedparagraph[list=test] \dorecurse{8}{\showparagraphshape\samplefile{tufte} \par} \stopshapedparagraph

or

\startshapedparagraph[list=test-repeat] \dorecurse{8}{\showparagraphshape\samplefile{tufte} \par} \stopshapedparagraph

Some more info is in the lowlevel-paragrsph document (part of the low level series).

This kind of features falls into the category 'fancy' (no one reqtested it), nice for posters and covers. It might evolve depending on needs for fancy features, but as said, it's currently a side track of metafun, so it's also in the category 'fun'. It's code for 'controlled' usage.

\starttext

\startuseMPgraphic{circle}     lmt_parshape [         path       = fullcircle scaled 136mm,         offset     = 2mm,         bottomskip = - 1.5LineHeight,     ] ; \stopuseMPgraphic

\start \startshapedparagraph[list=circle,mp=circle,repeat=yes,method=cycle]%

list=... refers to a previous \startparagraphshape definition, so mp=... tells ConTeXt that the definition is derived from MetaPost code instead. Just mp=... could be enough, but maybe "list=xyz,mp=xyz" makes it clear that mp is used to get a parshape from MetaPost instead of a \startparagraphshape definition.

    \setupalign[verytolerant,stretch,last]\dontcomplain

What's the meaning of \dontcomplain? Why is it needed there? BTW, \startparagraphshape, \stopparagraphshape, \startshapedparagraph, \stopshapedparagraph should be added to the .xml documentation files. The "right", "left", "both", "copy", "repeat" syntax in \startparagraphshape is really handy. Thanks, Massi
