In this post we handled a simple census command with limited attribute values. But what if the attribute value is /not/ pre-defined.
And assume that one can only use letters, numbers or spaces
@attribute/limit attribute=^[a-zA-Z0-9 ]+$
And we wanted a census command that outputs:
value 1: player, player2, and player3 value 2: player6, and player 8 value 3: player5, and player7 value 4: player9
One way, /abusing/ named registers (which will fail after X amount of unique named registers have been used up - as defined in @config) - is to do the following:
null(iter(lsearch(all,type,player,elock,attribute:*),setq(setr(a,edit(get(%i0/attribute),%b,_)),setunion(%q<%qa>,%i0))[setq(tlist,setunion(%q,%qa))])) [iter(%q,edit(%i0,_,%b): [itemize(%q<%i0>)],,%r)]
How would /you/ do this?
