inline-graphics and unwanted line-break

inline-graphics and unwanted line-break

[Peter Schorsch]

Hi, 

I have a small metapost graphic I like to use inline. But the arragement 
behaves a little bit "unpractically". As soon there is no character in front 
of the graphic context will break the line after the graphic - but as soon 
there is a character in front of the graphic, context does not adding a 
linebreak after the graphic.

Does anyone know how to prevent the line-break after the graphic if the 
graphic is the first inline?

Thanks, P.

example-file:

\startuseMPgraphic{zo}
	color schwarz ; schwarz := (.0,.0,.0) ;
 	draw 
(0pt,0pt)--(0pt,8pt)--(5pt,12pt)--(10pt,8pt)--(10pt,0pt)--(0pt,0pt)--cycle 
withcolor schwarz ;
\stopuseMPgraphic

\starttext

\hbox{\useMPgraphic{zo}} test text - why a line-break? How to prevent this?

a \hbox{\useMPgraphic{zo}} test text - this is fine: no line-break!

\stoptext

write \dontleavehmode\hbox{...}, this is normal TeX bahaviour and has nothing
special to do with ConTeXt.

the "a" starts horizontal mode but a \hbox did not and this can be
sometimes usefull

\hskip1sp\hbox{...}
the "invisible touch" effect :))

\hskip\zeropoint\hbox{} ;-)

\dontleavehmode
is
 \dontleavehmode=\quitvmode.
and \quitvmode is a primitive
stricly speacking we don't see a space, but a command that switch to a
mode to another.
And it's also sound good: you have put a command to change status.

\hskip\zeropoint\hbox{} ;-)
here we see a space of 0pt.
Can be a bit embarassing that "a horiz. space of 0pt" make  difference
between status,
because one can think "hey, a space of 0pt is nothing and should do nothing!"
(Of course, \hskip0t has sense )

\hskip1sp\hbox{...}
here we see a space of 1sp, ie (1/2^16) * 1pt which is invisible to human eye.
Here my "invisible touch" effect.
It's more "human" because i can say "hey, you have inserted a hor.
space very small, so small that you can see it,
but it's always a hor,. space not null, so it's reasonable  a change of state."

btw,
the context way is
\dontleavehmode
