Hi, in the following example the space before the “one” in the line \ctxlua{userdata.commalist(" one, two, three")} is visible in the output. I guess this counts as bug because in the assignment list the space before “a=x” is removed. Example: \starttext \startluacode userdata = userdata or {} function userdata.commalist(list) local list = utilities.parsers.settings_to_array(list) context.starttabulate() for index, value in next, list do context.NC() context.quotation(index) context.NC() context.quotation(value) context.NC() context.NR() end context.stoptabulate() end function userdata.parameters(list) local list = utilities.parsers.settings_to_hash(list) context.starttabulate() for key, value in next, list do context.NC() context.quotation(key) context.NC() context.quotation(value) context.NC() context.NR() end context.stoptabulate() end \stopluacode \ctxlua{userdata.commalist("one,two,three")} \ctxlua{userdata.commalist(" one, two, three")} \ctxlua{userdata.parameters("a=x,b=y,c=z")} \ctxlua{userdata.parameters(" a=x, b=y, c=z")} \stoptext Wolfgang
