I don't have the answer to your other questions but I do have an example for
this one.
It's not mine - I'm fairly sure it came from this list but I can't find who
that was any more.
\startluacode
userdata = userdata or { }
function userdata.mycommand(keywords, keyvals, str)
keyword_options = utilities.parsers.settings_to_array(keywords)
named_values = utilities.parsers.settings_to_hash(keyvals)
context('First option = ' .. keyword_options[1])
context('\\par')
context('Color chosen = ' .. named_values['color'])
context('\\par')
context('Curly braces = ' .. str)
context('\\par')
end
\stopluacode
\def\mycommand[#1][#2]#3{\ctxlua{
userdata.mycommand('#1', '#2', [==[#3]==])}}
\starttext
\mycommand[top, inmargin, now][color=green, roof=gabled]{Anne of Green Gables?}
\stoptext
