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
