Leave out reference to page if on the same page?

Suppose I have this fragment: is shown in \in{figure}[foo] on \at{page}[foo]. \placefigure [] [foo] I would like to leave the fragment “on \at{page}[foo]” out of the text if the figure ends up on the same page as the \at. Is that doable or is this a matter of manual tweaking at the end? G

Hi, In my ConTeXt archives I found the following example from a discussion on the mailing list: Wolfgang S. gave an answer which may help you: Best regards: OK %%%%%% begin test-ref.tex % %Am 16.01.2011 um 20:58 schrieb Robert Blackstone: % %Hi all, % %I wonder if it is already possible to perform the following task: % %I have to typeset documents that contain many pictures of various %sizes. Due to lack of space, some may pictures may not appear on the %page on which they are discussed. And also in the course of revising %the document, adding text may push them to another page. Therefore I %always refer to every picture with \in and \at. On the other hand, %changing or deleting text may unexpectedly land them on the correct %page. % %So sometimes it may happen that the reader, for instance on page 23, %will be referred to a figure on page 23, which looks rather silly. % %Is there a trick to let ConTeXt automatically omit the reference when %the picture happens to appear on the correct page (or change the %reference to « on this page »).

I suspect that Wolfgang meant to warn: ... internal macros (which can change) and /are not/ meant for users because that certainly appears to be the case. More specifically, the example (from 2011) fails, complaining about an undefined control sequence with \analyzecurrentreference. As others pointed out in related discussions, there is another serious shortcoming with this. References should be relative to the current page spread, which on doublesided layouts includes two pages, verso and recto. A reference to something on either of these pages is traditionally considered to be current, and above and below refer to previous and subsequent page spreads. There is a module, smartref, by Marco Patzer, that may address the needs of the original poster. It has some limitations, but generally addresses the issue quite well. See the list message at http://www.mail-archive.com/ntg-context%40ntg.nl/msg71889.html for more on smartref. (The primary limitation in my use is that it assumes that a following argument, as in \smartref{preceding}{following}[label], should follow the /at page number/ text, thus disabling the use of the following text to provide a subfigure label. Thus, one ends up with "see figure 6.4 at page 73a" instead of "see figure 6.4a at page 73".) -- Rik Kabel

Hi Rik, As a matter of fact the example given by Wolfgang works despite mkiv complaining about \analyzecurrentreference being unknown… Whent the typesetting stops because of this command, saying « run » or rather « r » continues the typesetting. I didn’t send the example module of Marco Patzer since it doesn’t seem to work anymore with recent versions of mkiv. Maybe Marco has a solution for his module?

I won’t trust this pagenumber check because when a reference appears at the begin of a page it can sometimes use the pagenumber of the previous page (hard to notice when you use \page in your examples to force a page break). Wolfgang

Do you have a example because I run the example at the end of the module and had no problems. What could be improved in the module is the check for left/right pages because the current check can fail when the reference appears at the begin of a page. Wolfgang

Hi, Thanks for your attention, Wolfgang: indeed removing \analyzecurrentreference from your example allows mkiv to typeset correctly and obtain the expected result. Regarding Marco Patzer’s smartref command, I can typest the following example if I \input directly \input conditionalfloatreferences.mkvi but invoking \usemodule[conditionalfloatreferences] does not work. (By the way I didn’t check whether the module is included in the minimals: so I am sending the file with this mail).

I think it’s better to use the version from github [1] which can be loaded with \usemodule[smartref]. [1] https://github.com/mpfusion/context-smartref Wolfgang

Hi Gerben, I think you are using mkii, while the code sent by Hans and containing \doifcheckedpagestate is intended for use with mkiv. Best regards: OK

Hi Gerben,

I suspected as such. I’m afraid to move to mkiv at this stage of my project. Is mkiv downwards compatible with mkii? What must I do to see if my project compiles with mkiv? I’m running currently commands like texexec --pdf —standalone —once prd_book.tex (all than not with —standalone and —once) G

Later for me. I read: Mark IV needs your input to be in UTF-8. Legacy documents using 8bit encodings have to be converted to utf-8 before they are usable. that enough is a show stopper for me at this point. All my input is in ascii code edited with a simple emacs-like editor. Moving to UTF8 at this stage is out of the question unless I get my editor to do that. G

Hi Gerben, Regarding the text encodings understood by mkii and mkiv, one can always use UTF-8 in both. Unless you have some very uncommon characters in your ascii file, the migration from ascii to utf-8 is quite easy, at least on a Mac (I don’t know what OS you are using): for instance you can open the file in an application such as Smultron or Fraise http://www.macupdate.com/app/mac/33751/fraise and then in the « Text » menu choose « Text encoding » and then « UTF-8 ». After that you save your file: now it is in UTF-8 encoding and can be typeset in mkiv, as far as the commands you use in your TeX file is compatible with mkiv.

The problem is not so much the Mac, but the old editor I use there. G

Hi,

Thanks for your attention, Wolfgang: indeed removing \analyzecurrentreference from your example allows mkiv to typeset correctly and obtain the expected result.

yet another sparsely documented feature ... in beta:

% new: \setupreferencing[doublesided=no]

\stoptext

if okay, then it's something to wikify ... should \setupreferencing[doublesided=no] be default? (currently yes i.e. spread aware)

keep in mind that this kind of functionality once it kicks in (is used) can result in a few more runs to get thing right and that there's always the danger of oscillation as the text injected is dependent on the situation

Hans

This looks very promising. When I test it with today's beta, I see that "current" is set in some iterations, but never shows up in the final version of the page, so references on the same page always come out as "backward" or "forward". I would think that the default should match the default for \setuppagenumbering[alternative=], and perhaps be tied to that. -- Rik Kabel

well, in the case of 5 alternatives current will only happen when the reference is at the *exact* spot as the thing referred to; so, in the case of text [target] text [reference] text the target is before the reference on the same page contrary to text \hbox to 0pt{[target]}\hbox to 0pt{[reference]} text of course 'current' seldom happens but it's part of the solution set anyway

Hi Rik,

As a matter of fact the example given by Wolfgang works despite mkiv complaining about \analyzecurrentreference being unknown… Whent the typesetting stops because of this command, saying « run » or rather « r » continues the typesetting.

How do you know it works? You only show that it runs to completion at that point. But without knowing what \analyzecurrentreference should do, not knowing if, for instance, it adjusts for certain edge cases, you do not have a reliable result.

...

I didn’t send the example module of Marco Patzer since it doesn’t seem to work anymore with recent versions of mkiv.

Maybe Marco has a solution for his module?

Best regards: OK

As Wolfgang wrote, the version on Github, which is referenced in the link I provided, works just fine, aside from the issue I described earlier. -- Rik
