Hi! Is it safe to leave spare comma at the end of the key=value list or other list of arguments? It is not nice, but when adding/commenting arguments in readable way (one per line) it's faster and while experimenting with parameters one doesn't have to care about the last comma adding or removing it back and forth, for example: \setuplayout[ grid=yes, %header=0mm, footer=7mm, %footerdistance=10mm, %cutspace=12mm, ] or \setuphead[ chapter, section, %subsection, %subsubsection, ][ textstyle=\ss, numberstyle=\ss, ] Thanks.

in most cases it is ok

in this case a space after 12mm is not that problematic because layout are calculated in vertical mode and the 12 mm is used in assignments
or
\setuphead[ chapter, section, %subsection, %subsubsection,
hm, here it can be troublesome unless i catch an empty case (not sure); if you run into troubles with such cases report it to the list and we can see if we can catch it
][ textstyle=\ss, numberstyle=\ss, ]

Thanks, I've found the example of the different behaviour, though the reason isn't the comma, but the space after the command, I think. So even writing parameters one-per-line (with space left behind = last one without comma or percent sign) can be dangerous. %\setuphead[chapter][style=\bfd] % works %\setuphead[chapter][style={\bfd}] % works %\setuphead[chapter][style={\bfd} ] % doesn't work %\setuphead[chapter][style={\bfd},] % works \starttext \chapter{Test chapter} \stoptext This is not seriuos, I just want to find, how the things work.

This is not seriuos, I just want to find, how the things work.
this is because the value of style is interpreted in its own special way; also, in {xx}<space> the become part of the value, and {\bfd} is ineffective due to grouping then Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
