I am trying to do a simple getcell on a named matrix in jit.gl.lua, and I think I am using the jit.listener incorrectly. Can someone give me some guidance?

listener = jit.listener(labymatrix.name, "listen")

outlet(0, table.concat(event.args, ", "))

labymatrix = jit.matrix("laby")
listener = jit.listener(labymatrix.name, "listen")
labymatrix:getcell(x,y)

--the "listener" function
function listen(event)
   outlet(1, event.subjectname)
   outlet(0, table.concat(event.args, ", "))
end

--begin LUA

this.outlets=2

function getcell(x,y)

labymatrix = jit.matrix("laby")
print(labymatrix:getcell(x,y))

end

--end LUA


i realize this doesn't really answer your question.

unfortunately, i know close to nothing about lua.

Thanks Rob -- this lead me to the solution!

For reasons I don't understand, the call to the variable containing the matrix has to be an argument to a function, like so:

You're right, this doesn't really show me how to use jit.listener -- but it shows me that at least in this case I don't need it! Yip!

--this works
eval(labymatrix:getcell(x,y))
-- end works

--this doesn't work
outputB = labymatrix:getcell(x,y)
--end doesn't work
