ref with the counter value












4














Is there some package providing a simple user interface to return the counter value (not the formatted cross-reference, as ref does) of a label? It seems neither zref, not refcount, nor cleveref, among others, provide it. cleveref saves the counter value to the aux file, but I couldn't find in the docs a macro to retrieve it (something like, say, numbercref), even if internally there is a cref@getcounter for that.



Please, note I'm not asking how to do it, just if there is a package with a simple user interface.

  • One 'disadvantage' with zref is that it is necessary to use zlabel -- i.e. zref does not hook into label as cleveref does -- the zlabel must be specified in addition to label

I have written crossreftools about one year ago, this package extracts information from cleveref labels with crtcrefnumber, this holds the number of the counter, using the special way how cleveref stores the information in its labels.



Traditional labels do not support this, since those labels apply thefoo, meaning that something like renewcommand{thefoo}{arabic{chapter}.Roman{section}.Alph{foo}} will store 4.II.C, for example. This way crtrefnumber will report the usual reference value but not the counter value of foo, 3 in the above example.



Most crt... macros are expandable.



The zref package is very sophisticated, but it does not provide means to store the counter value -- the counter name is quite easy to catch, by loading the counter module of zref, see a possible solution with zref at the end, however.



In total, crossreftools is not invasive as it just reevaluates the already stored label macros, whereas the second solution changes refstepcounter (marginally, however). If more information is to be stored with within labels, zref is most likely the better way to pursue.
