The \smartref command automatically refers to the section by number if it is available. If the user turns off numbering, the sections are referred to by title. I don't yet know if I do like it and how practical it is. It's an experiment. For those interested, the code is on Github¹.

Re: [NTG-context] Conditional float references
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.

That's on purpose. If the graphic appears on the same double page, it is visible and no further reference is printed. In traditional typesetting a single page is rather insignificant.

Re: [NTG-context] Conditional float references
Hi Marco, Your macro is a wonderful help to have smart references: I have not yet tried it with references to maths formulas, theorems, lemmas and such, but Iguess it should work as well. In order to help you nail down some small issues, here is how I used your module: I put the file you sent conditionalfloatreferences.mkvi in a folder (i.e. a directory) and then in a TeX file I put the following (not so) minimal example excerpted from your file %%% begin smartref-test.tex \usemodule[conditionalfloatreferences] \useMPlibrary [dum] %\setuppagenumbering [alternative=singlesided] \setuppagenumbering [alternative=doublesided] \starttext {\bf Test 1:} See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \page {\bf Test 2:} See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \startplacefigure [reference=fig:alpha] \externalfigure \stopplacefigure \startplacefigure [reference=fig:beta] \externalfigure \stopplacefigure \page {\bf Test 3:} See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \startplacefigure [reference=fig:gamma] \externalfigure \stopplacefigure \startplacefigure [reference=fig:delta] \externalfigure \stopplacefigure \page {\bf Test 4:} See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \page {\bf Test 5:} See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \stoptext %%% end smartref-test.tex The issues I noticed are the following: 1. Typesetting the file gives an error message when there is no \setuppagenumbering[alternative=doublesided] Actually it typesets if one ignores the error message (but some issues like the ones below remain). 2. In the above minimal example, when stating \setuppagenumbering[alternative=doublesided] then Test 2 and Test 3 do not result in the smart references expected (they both result in « See figure 1 and figure 3. » while Test 2 should give « See figure 1 and figure 3 on next page. », and Test 3 should result in « See figure 1 on previous page and figure 3. »). Thanks again for sharing your module.

[NTG-context] Conditional float references
Hi, a couple of times the question came up¹²³ how to create more intelligent referencing. There are already mechanisms in the core, namely \somewhere and \atpage but they both have drawbacks. \somewhere happily prints its text if the figure is placed on the same double page. In fact, no text at all should be printed if the figure is visible. Furthermore it's a little verbose to use unless hidden in a custom macro. \atpage on the other hand doesn't hesitate to print “see figure 1.2 at page 42” while you're on page 42. I'm aware that automatic generation of reference text is problematic since the text depends on the placement of floats which in turn depends on the text which might result in oscillation. I'm not sure how likely this is to occur in practice. I don't know if there's interest in integrating such functionality into the core. I attached some code, a new macro \smartref, which takes the same arguments as \in. \smartref{figure}[fig:somefigure] - it prints the reference if it is on the same page (e.g. Figure 1.2) - it prints the reference and a customizable text if the reference is on the next/previous page (e.g. Figure 1.2 on the previous page) - it prints the reference and the page if the reference is further away than one page (e.g. Figure 1.2 on page 42) - it adapts to single-sided and double-sided layouts Marco ¹ http://thread.gmane.org/gmane.comp.tex.context/65295 ² http://thread.gmane.org/gmane.comp.tex.context/59455 ³ http://thread.gmane.org/gmane.comp.tex.context/76001 \unprotect \unexpanded\def\strc_references_smart {\strc_references_start_goto \let\currentreferencecontent\currentreferencedefault \strc_references_pickup_smart_goto} \def\strc_references_pickup_smart_goto {\dodoublegroupempty\strc_references_pickup_goto_smart_indeed} \starttexdefinition strc_references_pickup_goto_smart_indeed #left#right#dummy[#label] \leftreferencetoks \iffirstargument {#left} \else \defaultleftreferencetoks \let\leftofreferencecontent\empty \fi \rightreferencetoks \ifsecondargument {#right} \else \defaultrightreferencetoks \let\rightofreferencecontent\empty \fi \doifreferencefoundelse{#label} {\goto{\referencesequence}[#label] \strc_references_check_visibility \ifreferenceisvisible\else \space\strc_references_smart_string \fi} {\let\currentreferencecontent\dummyreference \goto{\referencesequence}[#label]} \strc_references_stop_goto \stoptexdefinition \newif\ifreferenceisvisible \referenceisvisiblefalse \starttexdefinition strc_references_check_visibility \def\strc_references_smart_string{\labeltext\v!atpage\currentreferencepage} \referenceisvisiblefalse \ifnum\referencepagestate=\plusone %% 1 = reference on current page \referenceisvisibletrue \else \ifsinglesided \strc_references_do_relative_else\plusone {\def\strc_references_smart_string{\labeltext\v!nextpage}} {\strc_references_do_relative\minusone {\def\strc_references_smart_string{\labeltext\v!previouspage}}{}} \else \ifodd\realpageno \strc_references_do_relative_else\minusone {\def\strc_references_smart_string{\labeltext\v!previouspage} \referenceisvisibletrue} {\strc_references_do_relative_else\plusone {\def\strc_references_smart_string{\labeltext\v!nextpage}}{}} \else \strc_references_do_relative_else\minusone {\def\strc_references_smart_string{\labeltext\v!previouspage}} {\strc_references_do_relative_else\plusone \referenceisvisibletrue{}} \fi \fi \fi \stoptexdefinition \starttexdefinition strc_references_do_relative_else #relativepagenumber \ifnum\currentreferencerealpage=\numexpr\realpageno+#relativepagenumber\relax \expandafter\firstoftwoarguments \else \expandafter\secondoftwoarguments \fi \stoptexdefinition \let\smartref\strc_references_smart \startinterface all \setinterfacevariable {previouspage} {previouspage} \setinterfacevariable {nextpage} {nextpage} \stopinterface \setuplabeltext [\s!en] [\v!atpage=on page\nobreakspace, %% “at page” sounds weird \v!previouspage=on the previous page, \v!nextpage=on the next page] \protect \useMPlibrary [dum] \setuppagenumbering [alternative=doublesided] \starttext See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \page See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \startplacefigure [reference=fig:alpha] \externalfigure \stopplacefigure \startplacefigure [reference=fig:beta] \externalfigure \stopplacefigure \page See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \startplacefigure [reference=fig:gamma] \externalfigure \stopplacefigure \startplacefigure [reference=fig:delta] \externalfigure \stopplacefigure \page See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma]. \page See \smartref{figure}[fig:alpha] and \smar
