Hi Henri, Thank you for your suggestion.

The problem with integrals is that they don't adapt because they are not wrapped as delimiters (like left/right stuff). If \int were a command taking an argument it would be easier. As in: \starttext \setupmathextensible[integral][rightoffset=-3mu,exact=yes,factor=2] \startlines \ruledhbox{$\integral f\frac{1}{2}$} \ruledhbox{$\integral[factor=1] f\frac{1}{2}$} \ruledhbox{$\integral[factor=3] f\frac{1}{2}$} \stoplines \startformula a = \autointegral{t}{b}1 + \autointegral{t}{b}{\frac{\frac{3}{4}}{\frac{1}{2}}} + \autointegral{t}{b}{\frac{\frac{\frac{\frac{1}{2}}{2}}{2}}{2}} \stopformula \stoptext

Hi Hans, Hi list,

This is similar to what we have discussed earlier on this list and elsewhere regarding \over vs. \frac. (I agree with Knuth that {a \over b} is *much* more readable in running source code than \frac{a}{b} but have resigned myself to use \frac{}{}, as this can be made better behaved and gives a much better result.)

Other traditional TeX constructs like \int^a_b have their charm (and need to remain supported, just like is \over), but I support introducing and encouraging the use of new constructs like your example below. An alternative syntax (that could co-exist) would be admitting $\left\int ... \right.$, but I do not know what limitations there might be with both the (luatex) engine and with ConTeXt.

the tricky part there is that int has super and subscripts while left / right are different animals ... i looked into this (in the engine) and decided to delay implementing that (i might do it some day but it's sort of tricky to keep compatibility) also, ints are upright (extensible or stepwise sizes) or slanted (stepwise sizes) so even if we support something there are some limitations due to lack of font support (could be dealt with in due time)

The problem with extensions, like always, in straying from traditional TeX is interchangeability of code, or, more importantly, in the learning curve obstacles that this introduces to traditional TeX (and LaTeX) thinking. I know that at some level we do not care, for we often make (good) design choices that improve the syntax of ConTeXt.

Perhaps we can use this thread to discuss other cases (like \sum, ...) that present difficulties and then decide on good solutions.

sure ... Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Hi Hans, Thanks for your solution. I created a macro, is it "robust" ? Fabrice

\setupmathextensible[integral][rightoffset=-3mu,exact=yes,factor=2]

\unexpanded

\def\integ#1#2#3{\math{\autointegral{#1}{#2}{#3}\diff x}}

\starttext \integ{4}{1}{g(x)} \stoptext
