You can save the content in a buffer and process the content with Lua.
\startluacode
userdata = userdata or { }
userdata.linescontent = userdata.linescontent or { }
local linescontent = userdata.linescontent
function linescontent.process()
local lines = string.splitlines(buffers.getcontent("linescontent"))
context.startlines()
for i=1,#lines do
local l = lines[i]
if i == 1 then
context("{\\bf %s}",l)
context(true)
elseif i == 2 then
context("{\\tt %s}",l)
context(true)
else
context("%s",l)
context(true)
end
end
context.stoplines()
end
\stopluacode
\def\startlinescontent
{\grabbufferdata[linescontent][startlinescontent][stoplinescontent]}
\def\stoplinescontent
{\ctxlua{userdata.linescontent.process()}}
\starttext
\startlinescontent
One
Two
Three
Four
Five
Six
\stoplinescontent
\stoptext
