[NTG-context] Wrong float numbering with default=top
Hi, The setting \setupfloat [figure] [default=top] not only places the figures at the top of the page, but also messes up the float numbering (the float placement is fine).

Re: [NTG-context] A problem with autopunctuation
Hi, all, Hans has done some work on autopunctuation which made it into yesterday's beta (2012.12.03 11:33). This includes a 'set it like I type it' mode people have been asking for. There are now three options to \setupmathematics[autopunctuation=...]: * autopunctuation=no — default TeX behaviour. Commas get a thin space, periods get nothing. * autopunctuation=yes — manual control for commas. Commas followed by a space get a thin space; periods, and commas followed by something else, do not. * autopunctuation=all — like `yes`; and periods, too, get a thin space unless suppressed Example code below, example output attached, and the behaviour is documented at http://wiki.contextgarden.net/Command/setupmathematics Cheers, Sietse \defineparagraphs[asdf][n=3] \startTEXpage[offset=2mm] \startasdf \setupmathematics[autopunctuation=no] autopunctuation=no \starttabulate[] \NC input \NC desired \NC output \NC \NR \NC 2,5 \NC 2, 5 \NC $2,5$ \NC \NR \NC 2, 5 \NC 2, 5 \NC $2, 5$ \NC \NR \NC 2.5 \NC 2.5 \NC $2.5$ \NC \NR \NC 2. 5 \NC 2.5 \NC $2. 5$ \NC \NR \stoptabulate \asdf \setupmathematics[autopunctuation=yes] autopunctuation=yes \starttabulate[] \NC input \NC desired \NC output \NC \NR \NC 2,5 \NC 2,5 \NC $2,5$ \NC \NR \NC 2, 5 \NC 2, 5 \NC $2, 5$ \NC \NR \NC 2.5 \NC 2.5 \NC $2.5$ \NC \NR \NC 2. 5 \NC 2.5 \NC $2.5$ \NC \NR \stoptabulate \asdf \setupmathematics[autopunctuation=all] autopunctuation=all \starttabulate[] \NC input \NC desired \NC output \NC \NR \NC 2,5 \NC 2,5 \NC $2,5$ \NC \NR \NC 2, 5 \NC 2, 5 \NC $2, 5$ \NC \NR \NC 2.5 \NC 2.5 \NC $2.5$ \NC \NR \NC 2. 5 \NC 2. 5 \NC $2. 5$ \NC \NR \stoptabulate \stopasdf \stopTEXpage punctuation-001.pdf Description: Adobe PDF document ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

In MKII we had a mechanism that took care of that (out of line flushing
of floats) but it never made it into mkiv (if only because some folks
didn't like it).
As an experiment I've added some trickery. But keep in mind that messing
with numbers is never 100% foolproof. So, for the moment you can say
\ctxlua{structures.lists.autoreorder = true}
till we're sure about what level of control is needed. Beta later today.

[NTG-context] Place figure here; jumping over sections
Hi, How to specify that I prefer to place figure here in the following code? \startplacefigure \externalfigure[settings_window.png][scale=1000] \stopplacefigure I don't understand, why figures are encouraged to jump across sections and subsections? It makes no sense. Is there a way to prohibit this (e.g., flush all figures at section end, possibly for the cost of white space at page bottom)? At least I could see where problems are, instead of keeping an eye whether figures still belong to their sections.

Hi Hans,
Thank you for the fixes and adding the commands \notin and \imply: I did some
testing with your examples and others of my own, and it seems that some of the
issues are fixed.
However with
\enablemode[lmmath]
the command \notin does not work as expected, while when the above command is
commented out it does.
Another issue is that the size of integrals when using palatino, times or
termes is the almost the same as the ones in inline maths, and I think that
this is not the correct behaviour.
The examples I tested are essentially yours:
