Test if tikzmark exists on same page












4















Apologies for flooding the site with tikzmark problems ... :)



I know that with iftikzmark I can test if a given tikzmark exists in general. Is there a way to test if a particular tikzmark exists on the same page?



Use case: I'm trying to design macros that I can insert anywhere in a text that would draw a line between them –- a linestart and a linefinish command. However, when the linefinish command happens to fall on a subsequent page, the line gets drawn to where the linestart command was on the previous page. I would rather have it instead "do something else", here, just for purpose of illustration, draw me a black square – or, ideally "point across" the page in the direction to where the other mark is sitting.



In the code below, I've tried to construct what I'm envisioning using iftikzmark but that does not work.



documentclass{article}
usepackage{tikz}
usetikzlibrary{tikzmark}
newcounter{tikzmkstart}setcounter{tikzmkstart}{0} %
newcounter{tikzmkfinish}setcounter{tikzmkfinish}{0} %

newcommand{linestart}{%
stepcounter{tikzmkfinish}iftikzmark{bthetikzmkfinish}{% tikzmark exists on same page
stepcounter{tikzmkstart}tikzmarknode{athetikzmkstart}{vphantom{x}}addtocounter{tikzmkfinish}{-1}}
{% tikzmark doesn't exist on page
begin{tikzpicture} draw [line width=4] (0,0) -- (.1,0); end{tikzpicture}addtocounter{tikzmkfinish}{-1}}}% black square if linefinish on next page

newcommand{linefinish}{%
iftikzmark{athetikzmkstart}{% tikzmark exists on same page
stepcounter{tikzmkfinish}tikzmarknode{bthetikzmkfinish}{vphantom{x}}begin{tikzpicture}[remember picture] draw[overlay] (athetikzmkstart.west) -- (bthetikzmkfinish.west); end{tikzpicture}}
{% tikzmark doesn't exist on page
begin{tikzpicture} draw [line width=4] (0,0) -- (.1,0); end{tikzpicture}}}

begin{document}
Text linestart text text

Text text text
%newpage

Text text linefinish text
end{document}


Any ideas of how else I might accomplish something like this would be very welcome!

  • The way you write the questions may indicate that you are about to construct a tikzmar version of something like this answer. The basic trick is that you build in the page number.

  • @marmot Oh, you mean incorporating the pagenumber into the label for the node. Ha, that's clever.

  • Yes, basically. If you also want the line to also run over page breaks, you may need refcount, like in Gonzalo's answer.

    tikzmark already saves the page number on which it is defined (see tex.stackexchange.com/q/79121/86 for a use of this, and look at next page in the documentation). There isn't a current direct interface to that information; it is stored as save@pg@<picture id of the tikzmark> so you could do a test on that. I'm not going to attempt to get the expansions right in a comment, but something like ifnumcsname save@pg@pgfpictureidendcsname=csname save@pg@csname save@pt@tmk@labelendcsnameendcsname

I can see the point of having a iftikzmarkonpage conditional, so I've added it to the tikzmark package (download tikzmark.dtx and run tex tikzmark.dtx to get the latest version). This introduces a new conditional, iftikzmarkoncurrentpage{<tikzmark name>}. That copes with the issue about the lines being drawn on both pages when needed.

    @jan You can use tikz-pagenodes, which has the current page text area node. And I think you are doing it right because in their present form the questions and answers are useful for many, which they are not if you do some highly specialized things. (Will be off now.)

  • That looks like it does what I'm after :) thank you ... and if you incorporate a conditional into the package, even better :) Although ... didn't Gonzalo's answer solve that? Why would his solution be bad?

    @jan You can use tikz-pagenodes, which has the current page text area node. And I think you are doing it right because in their present form the questions and answers are useful for many, which they are not if you do some highly specialized things. (Will be off now.)

I can see the point of having a iftikzmarkonpage conditional, so I've added it to the tikzmark package (download tikzmark.dtx and run tex tikzmark.dtx to get the latest version). This introduces a new conditional, iftikzmarkoncurrentpage{<tikzmark name>}. That copes with the issue about the lines being drawn on both pages when needed.
