I can't figure out how to determine the number of pages of a PDF
file within lua. From the TeX side it works with
\getfiguredimensions

Can somebody give me a nudge in the right direction? Example:

\starttext

% Works
%\getfiguredimensions [somefile.pdf]

\startluacode
        -- Does not work
        context.getfiguredimensions({"somefile.pdf"})

        local numpages = figures.get("used", "pages", 0)
        context(numpages)
\stopluacode

\stoptext

something

     local fig = figures.push { name = "somefile.pdf" }
     figures.identify()
     figures.check()
     local nofpages = fig.used.pages
     figures.pop()
