Hello, I'd like to restart the thread about "object-orienting" section commands. Availability of \startpart ... \stoppart, \startchapter ...\stopchapter (alongside the faster \part, \chapter ... alternatives) becomes more and more a need for me. Having the mechanism standardized in ConTeXt would be a great thing. This is the way I'm implementing it by hand: %D New structured sectioning \newtoks\everybeforestartpart \newtoks\everyafterstartpart \newtoks\everystoppart \def\startpart{\dosingleempty\dostartpart} \def\dostartpart[#1]#2{% \bgroup\bgroup \the\everybeforestartpart \iffirstargument \part[#1]{#2}% \else \part{#2}% \fi \egroup \the\everyafterstartpart } \def\stoppart{\the\everystoppart\egroup} Using this snippet as the kernel and simply changing "part" to whatever other sectioning level is needed is enough to allow full customization of the sectioning levels. Can this be put in ConTeXt? -- Giuseppe "Oblomov" Bilotta

After a few tries, I discovered that it's much better without the inner grouping: \newtoks\everybeforestartpart \newtoks\everyafterstartpart \newtoks\everystoppart \def\startpart{\dosingleempty\dostartpart} \def\dostartpart[#1]#2{% \bgroup \the\everybeforestartpart \iffirstargument \part[#1]{#2}% \else \part{#2}% \fi \egroup \the\everyafterstartpart } \def\stoppart{\the\everystoppart} -- Giuseppe "Oblomov" Bilotta

This is without the outer grouping. I think the outer grouping is necessary; when I use \start \stop commands I expect them to make a group. Could not you do without the if statement? \def\dostartpart[#1]#2{% \bgroup \the\everybeforestartpart \part[#1]{#2}% \the\everyafterstartpart } \def\stoppart{\the\everystoppart\egroup} -- Simon Pepping email: spepping@scaprea.hobby.nl

Right indeed. SP> Could not you do without the if statement?

I've had problems with some arguments which behave differently depending on whether the argumet is not there or is empty, so I prefer to keep on the safe side. -- Giuseppe "Oblomov" Bilotta
