Not with the current implementation of the environment because it doesn’t
know how many lines are there. With a Lua based solution it would be simple
to add a mechanism to prevent a page break at a certain region because
the needed information are available.
\startluacode
userdata = userdata or { }
userdata.linescontent = userdata.linescontent or { }
local linescontent = userdata.linescontent
function linescontent.process()
local lines = string.splitlines(buffers.getcontent("linescontent"))
context.begingroup()
for i=1,#lines do
local l = lines[i]
context("%s",l)
context.par()
end
context.endgroup()
end
\stopluacode
\def\startlinescontent
{\grabbufferdata[linescontent][startlinescontent][stoplinescontent]}
\def\stoplinescontent
{\ctxlua{userdata.linescontent.process()}}
\starttext
\startlinescontent
One
Two
Three
Four
Five
Six
\stoplinescontent
\stoptext
