Hi Florian,
The following setup works fine here, I wonder whether this is what you want:
\defineenumeration[theorem]
  [text={Theorem},
  style=slanted,
  title=yes,
  alternative=hanging,
%	hang=2,
  width=fit,
  right={~},
  way=bychapter,
%	way=bysection,
  prefix=yes,
%	prefixsegments={chapter:section},
  prefixsegments={chapter},
  ]
Another more versatile solution is to define an enumeration like the \proclaim definition of plain TeX, as follows:
\defineenumeration[proclaim]
  [text=,
  style=slanted,
  title=yes,
  titleleft=,
  titleright={.},
  alternative=hanging,
%	hang=2,
  width=fit,
  right={~},
  way=bychapter,
%	way=bysection,
  prefix=yes,
%	prefixsegments={chapter:section},
  prefixsegments={chapter},
  ]
and the use it as in the following example:
\startproclaim{Pythagoras Theorem}
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
\stopproclaim
You can play with other options in the setups above and tune them to your taste.
Best regards: OK

Dear list,
I am trying to use enumerations with MKIV I am a bit at a loss when it comes to the documentation (see below for a few issues).
Working on a concrete example, I have come pretty close to what I want for my enumeration ‘theorem’:
\setupexternalfigures[location=default]
\setupenumerations[
  alternative=left,
  text=Theorem,
  headstyle=bold,
  title=no,
  way=bychapter,
  stopper={:},
  distance=1ex,
  width=fit,
  style=normal,
  hang=fit]
\defineenumeration[theorem]
\starttext
\chapter{First chapter}
\starttheorem
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
\stoptheorem
\chapter{Second chapter}
\placefigure[right, none]{}{\externalfigure[mill]}
\starttheorem
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
\stoptheorem
\stoptext
QUESTIONS:
1) I would like to prefix the theorem counter with the chapter number, such that the number of the second theorem becomes 2.1. Can this be done?
2) Is it possible to circumvent the misplacement of the second theorem due to the placed figure? Ideally, the theorem would just use the space to the left it.
Issues with the documentation:
- In “ConTeXt Commands”, it says on page 224 that \setupenumeration inherits from \setupcounter; but in “ConTEXt reference manual", it says on page 246 that \setupenumerations inherits from \setupdescriptions.
- In “ConTEXt reference manual”, the key “location” for \defineenumeration should probably replaced by “alternative”. Right now, all examples on page 247 are unaffected by this setting and hence look the same.
- The wiki seems to use MKII, which makes a difference for the example on http://wiki.contextgarden.net/Command/enumeration, which compiles differently under ConTeXT online.
Thanks for your help!
Best regards,
Florian

Dear Otared and Wolfgang,

thanks for your helpful suggestions and information!

One problem, however, persists: The theorem environment gets misplaced when a figure is placed to its left:

\setupexternalfigures[location=default]
\setupenumerations[
	alternative=left,
	text=Theorem,
	title=no,
	stopper={:},
	distance=0ex,
	width=fit,
	right={~},
	style=normal,
	hang=fit]
\defineenumeration[theorem]
\starttext
\placefigure[right, none]{}{\externalfigure[mill]}
\starttheorem
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
\stoptheorem
\stoptext

Does anyone know a way to fix this?

Thanks and best regards,
Florian
