I'd like to add some area for readers to write in the margins of some text. This would leave three lines, like this to the right of the text.
__________________
The passage would take up about the left 60% of the text and the margin note space about 30% of textwidth, so no need to use the margins.
Though its easy for me to implement this code using some \thinrules and manually dropping macros in the text, is there some way ConTeXt can be told to just add them to right of every paragraph (at the start of the paragraph)?
Sample:
This is some text ________
that is written in ________
the passage and ________you can see the th-ree lines to the right.The text in the para-graph continues eventhough there arejust three lines tothe right.
Here is another par- ________agraph. ________ ________
Here is yet another ________paragraph. You can ________see it also has the ________three liens.
This is just for a segment of the book, not every paragraph in the book.

Is it okay if there are rules continuously down the right column? If so,
this is fairly simple to do with layers/backgrounds + MetaFun.
If you want for there to be exactly three rules per paragraph, then that
is more complicated. I can think of some bad solutions (\everypar, Lua
callbacks), but I'll leave it to someone else to think of a good
solution.
Thanks,

Hello Max,
It is preferred if the solution is just three lines per paragraph, rather than some content parallel to the text...I'll be modifying whatever solution to fix a bunch of other situations (e.g. display a box next to each paragraph).

A Lua callback solution:
\startluacode
-- Constants
RULE_OFFSET = tex.sp "1em"
RULE_THICKNESS = tex.sp "0.4pt"
RULE_LENGTH = tex.sp "3cm"
-- Callback
function userdata.lines(head)
if status.output_active or
tex.nest.ptr > 1
then
return head
end
local i = 0
for n in node.traverseid(node.id "hlist", head) do
i = i + 1
if i > 3 then
break
end
local offset = node.new "glue"
offset.width = RULE_OFFSET
node.slide(n.list).next = offset
local rule = node.new "rule"
rule.width = RULE_LENGTH
rule.height = RULE_THICKNESS
rule.depth = 0
offset.next = rule
end
return head
end
nodes.tasks.appendaction(
"finalizers",
"after",
"userdata.lines"
)
\stopluacode
\parskip=\baselineskip
\starttext

An \everypar solution:

\relax%

Neither of these solutions are great though. Both of these solutions are
pretty low-level, so there's presumably a more ConTeXt-y way of doing
this.

You can use the \EveryPar register but \everypar is off limits.

When I use the code given, it compiles and displays fine. But when I try replacing \everypar with \EveryPar, it halts during compiling with this complaint:
"A number should have been here; I inserted '0'. (If you can't figure out why I
needed to see a number, look up 'weird error' in the index to The TeXbook.)
mtx-context | fatal error: return code: 1

These both work great, but do that for the whole document? Is there a way to restrict it to only apply the lines to some parts of the file, not every single paragraph?

solution instead:
