Hi Marco,
Thanks for your answer: indeed I was wrong about the issue I reported about
doublesided page numbering. The reason is that I use TeXShop (on a Mac) and the
PDF produced is shown in a single page layout (it is however possible to have
doublesided layout as well: that's what I tested after your answer.
Also after applying your patch everything works as expected. I tested your file
with some maths formulas and changed even the language to French with:
\unprotect
\setuplabeltext
[\s!fr]
[\v!atpage=page\nobreakspace, %% “at page” sounds weird
\v!previouspage=à la page précédente,
\v!nextpage=à la page suivante]
\protect
\mainlanguage[fr]
without any problem. So your macro is just wonderful!
However maybe it would be better to have some setup options like:
\setuplabeltext[smartref][atpage={page},
previouspage={à la page précédente}, %or {page
précédente}
nextpage={à la page suivante}] %or {page suivante}
In case Hans is willing to add such capabilities to the cross referencing, it
would be great if one could setup the cross references in the same way by
saying for instance
\setupreferencing[alternative=smartref]
and then have \smartref be defined automatically.
A final remark concerns the possibility to visualize the reference points when
one is in the process of proof reading: at least in maths, it is usual to have
dozens of reference points to formulas, lemmas, theorems, etc, and it is quite
useful to be able to visualize such things. For instance I use a quick and
dirty macro to print in the margin « eq:Fermat » to the right of the following
formula
\placeformula[eq:Fermat]
\startformula
a,b,c \in {\Bbb N}^*, \quad n \geq 3, \quad a^n + b^n = c^n \imply abc = 0.
\stopformula
when I am preparing a paper. I do the same with references to lemmas and
theorems, but I print them in the margin to the left of the reference point.
For now, mkiv does not support such things and it's a pity.
Best regards: OK
