[NTG-context] Line break after a Metapost picture at start of paragraph

[NTG-context] Line break after a Metapost picture at start of paragraph

Hi,

I have just encountered a (to me) slightly surprising behaviour in ConTeXt
LMTX 2024.10.31: there seems to be an automatic line break after a Metapost
picture if it is at the start of a paragraph. Here is a simple example
showing this behaviour:

------------------------------------------------------------------
\starttext
% Two different lines
\startMPcode
    fill fullcircle scaled 10pt;
\stopMPcode
text

% Single line
text
\startMPcode
    fill fullcircle scaled 10pt;
\stopMPcode
\stoptext
------------------------------------------------------------------

I'm not sure whether this is a bug or intended behaviour, though - maybe
this is the expected  output for users more familiar with TeX and/or
ConTeXt than I am. I would have two question, though:

1) Is there a canonical way to get the second behaviour (multiple Metapost
pictures and text on the same line) if the first Metapost picture starts
the paragraph? One workaround seems to be to add \noindent (plus \hskip if
I do want indentation) before the first Metapost picture, but maybe there
is a better way.

2) If this is intended behaviour, is there already a description of it in
the Wiki or would it make sense for me to add it?

Cheers,
Florent

Hi,

If you add \dontleavehmode before the MP graphic that starts the line,
you will be fine. There is something to read about it here:

Hi Mikael,

Thanks a lot for the info and for pointing me to this page, which has
other very useful tips I was not aware of!

Cheers,
Florent
