Hello,
still a problem - consider the following code:
----
\ifx\startpapersize\undefined
\unprotect
\def\startpapersize{\page\pushmacro\page_paper_restore\setuppapersize}
\protect
\fi
\ifx\stoppapersize\undefined
\unprotect
\def\stoppapersize{\page\popmacro\page_paper_restore\setuppapersize}

\startluacode
local tomm = function(v) return v * (210 / 39158276) end
pgsz = function()
context("w=%.1f, h=%.1f", tomm(tex.dimen.paperwidth),
tomm(tex.dimen.paperheight))
end
\stopluacode
%
\starttext
A
\ctxlua{pgsz()}
\startpapersize[A3,landscape]
B
\ctxlua{pgsz()}
\stoppapersize
\startTEXpage[width=200mm,height=100mm]
C % 3rd page
\ctxlua{pgsz()}
\stopTEXpage
the papersize of a TEXpage is known when that page is flushed and when
you ask for it the way you do now tex is still constructing the box
it's all a matter of timing
\starttext
\appendtoks
\ctxlua{
print(
number.topoints(tex.dimen.paperwidth ),
number.topoints(tex.dimen.paperheight)
)
}%
\to \everyshipout
\setuppapersize[A4] test
\startTEXpage test \stopTEXpage
\setuppapersize[A3] test
\stoptext
\stoptext
----
In the case of 3rd page (with text "C"), page size "w=210.0, h=297.0" is
printed instead of "w=200.0, h=100.0".
So how to access values 200 and 100 mm for the page produced by
\startTEXpage[width=...,height=...]?
Best regards,
Lukas

If by messing it’s meant modifying their values, I agree that’s a bad
idea 😊, the requirement is likely to read the value only (at least this
is my usage of these in shipouts « after » callback).
If these are not reliable, what’s the reliable way to get the page width
and height ?
\starttext
\ctxlua{context(number.topoints(tex.dimen.paperwidth))}
\ctxlua{context(number.topoints(tex.dimen.paperheight))}
\stoptext
