[NTG-context] page range reference (how to compare references)
Hello list,
I'm trying to reference a page range (think of a long quote spanning on
2 pages).
I need to discriminate ranges collapsing to one page from "real" ranges
(2 or more pages): "1-1" should become "1", while "1-2" should stay
like that.
Here's a not working snippet:
\starttext
Tufte quote at p.
\at[tufte:start]\doifelse{\ref[realpage][tufte:start]}{\ref[realpage][t
ufte:stop]}
{}
{-\at[tufte:stop]}
% start of quote reference
\pagereference[tufte:start]
\input{tufte}
%\page % comment/uncomment this to toggle from range to single page
\input{tufte}
% end of quote reference
\pagereference[tufte:stop]
\stoptext
The \doifelse is always false, I think because \ref[realpage][...] is
not a string.
Thanks in advance.
BTW, best wishes for next week's meeting (hoping to join next year).
Best regards,
Massi

Re: [NTG-context] Size of the last shipped page by Lua?
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}
\protect
\fi
%
\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
\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

Re: [NTG-context] page range reference (how to compare references)
I found a solution, but it's tricky (and there's no check on reference
existence in structures.references.collected).
\directlua{
function userdata.printrange(singular, plural, label)
local coll_ref = structures.references.collected[""]
local pagestart = coll_ref[label .. ":start"].references.realpage
local pagestop = coll_ref[label .. ":stop"].references.realpage
if pagestart == pagestop then
context(singular)
else
context(plural)
end
context("~")
context.ref({"page"}, {label .. ":start"})
if pagestart ~= pagestop then
context("-")
context.ref({"page"}, {label .. ":stop"})
end
end
function userdata.printpagerange(label)
userdata.printrange("page", "pages", label)
end
}
\def\printpagerange#1{\ctxlua{userdata.printpagerange("#1")}}
\starttext
Tufte quote at \printpagerange{tufte}.
% start of quote reference
\pagereference[tufte:start]

page
