Oh, that's nice, but the \setupsomething part is still missing, i.e. I still want to be able to invoke \somethingparameter{...}. My question is about merging two tasks in one in a better way than the one I proposed, if possible. Thanks for the help.

Hi, list! I hope my example shows clearly enough what I intend to do:

\startluacode

userdata = userdata or {}

userdata.mydata = {}

local function registermydata(data,...)

table.insert(userdata.mydata, data)

end

interfaces.implement{

name = "registermydata",

arguments = "2 strings",

actions = registermydata

}

\stopluacode

\unprotect

\def\mysetups[#1]%

{\getdummyparameters[#1]%

\processassignmentlist[#1]\clf_registermydata}

\protect

\starttext

\mysetups[love=nice,hate=awful]%

\dummyparameter{love}

\cldcontext{userdata.mydata[2]}

\stoptext

What I want to know is if there's a less hackish way to pass keys (yep, only keys, not values) to Lua using \getdummyparameters (actually I'm using an user-defined \setupsomething, but it's more or less the same) and \processassignmentlist. Is it possible, for instance, to automatically pass a key to Lua when it's set in \setupsomething? Thanks in advance.

PS: Sorry if I missed something in the test suite again It's probably somewhere ...

\startluacode

userdata = userdata or { } userdata.mydataA = { } userdata.mydataB = { }

interfaces.implement { name = "RegisterMyDataA", public = true, arguments = { "hash" }, actions = function(t) for k, v in pairs(t) do table.insert(userdata.mydataA,k) end end, }

interfaces.implement { name = "RegisterMyDataB", public = true, arguments = { "array" }, actions = function(t) for k, v in ipairs(t) do table.insert(userdata.mydataB,string.split(v,"=")[1]) end end, }

\stopluacode

\unprotect

\protect

\starttext

\RegisterMyDataA[love=nice,hate=awful]% \RegisterMyDataB[love=nice,hate=awful]%

\cldcontext{userdata.mydataA[2]} % unordered \cldcontext{userdata.mydataB[1]} % ordered

\stoptext
