 Hangaround is a very robust command and works in more cases than
 \placefigure[left] but you have a conflict with the \item command
 which place the itemize symbol before the following text which
 is indented in your case.

Dear ConTeXt list,

I apologize for digging up an old thread. I was searching for
\starthangaround[right] and found this thread. I tried the code that
Wolfgang gave in this thread but I guess something has changed since then,
because it does not work with latest minimals. Would it be possible to get
(a working) version of \starthangaround[right]? I think it even would be
nice to have it in the core.

As a minimal nonworking example, see the email from Wolgang in this thread.

With best regards, Mikael

Hi Mikael,

The example given by Wolfgang works fine for me with mkii, but not in mkiv: 
probably something has changed in mkiv, for example the way [scale=500] must be 
used in mkiv.

Best regards: OK

Hi Otared,

thank you for your answer. I work in mkiv, so I have to wait for a fix if
there will be one.

(I work in a two-column document, so \placefigure[right]... does not work,
it seems, otherwise I could have used that)

Hi,

I combined some functionality into:

\showframe

\starttext

\starthanging{\externalfigure[cow][scale=500]}
\input tufte
\stophanging

\blank

\starthanging[right]{\externalfigure[cow][scale=500]}

\stophanging

\blank

\starthanging[location=right,n=2,distance=1cm]{\externalfigure[cow][scale=500]}

\stophanging

\stoptext

after all, these were yet unofficial commands

Thank you Wolfgang, nice example, ... of code and output, of course.

 Hangaround is a very robust command and works in more cases than
 \placefigure[left] but you have a conflict with the \item command
 which place the itemize symbol before the following text which
 is indented in your case.
And even if I use
code
\startitemize[n,inmargin]
/code
I got 2 not in margin. Something similar I know about wrapfig package
for LaTeX. It could 'wrap' text around figure or table while it
couldn't work within list environment (start/stop).

Ok, that only means that I don't understand how lists and this
'environment' work.

Re: [NTG-context] Q about hangaround commands

2010-11-02 Thread Vladimir Lomov
Hi.

Some answers I found myself :)

2010/10/26 Vladimir Lomov lomov...@gmail.com:
 Hi.

 I'm trying to figure out the limitation of \start/stophangaround commands.

 1. Is it correct that currently the figure could be placed only on
 left? If so is it easy to extend the command to allow placing figure
 at right side?
 2. Is there way to increase/decrease the space between the text and image?
 3. Is it correct that hangaround command is tricky hack that change normal 
 flow?
2. - \setuphanging[desitance=0.7em], for example.
3. - To make '2.' appear on left side it is enough to put empty line
between \item and
\starthangaround. IMHO, this is workaround, not solution.

P.S. I have feeling that feature like 'hangaround' doesn't fit well
with tex (page layout ...?) model.

[NTG-context] Q about hangaround commands

2010-10-26 Thread Vladimir Lomov
Hi.

I'm trying to figure out the limitation of \start/stophangaround commands.

1. Is it correct that currently the figure could be placed only on
left? If so is it easy to extend the command to allow placing figure
at right side?
2. Is there way to increase/decrease the space between the text and image?
3. Is it correct that hangaround command is tricky hack that change normal flow?

I prepare simple example (it is attached). 1) is obvious from the
example (default behavior I assume). 3): I got the '2.' not on left
side as 1) and 3) but on left side of text block right after image.
Another example if 3): if I put empty line between \starthangaround
and \input (see the file) then there would be mess.

P.S. I tried the example with MkIV only.
