That merely goes to show that the problem does not have
a one-size-fits-all solution. Even small programs re-implement this.
E.g. I use a collector object, and usually don't even bother to find
an existing program that has one. I just type it in every time.
do
local collect = {__index =
function(tbl,x) rawset(tbl,#tbl+1,x) end
}
function collector()
return setmetatable({},collect)
end
end
words = collector()
("the quick brown fox jumps over the lazy dog"):gsub("%S+",words)Sometimes the collector has added functionality, e.g. FIFO or
LIFO retrieval.
I don't expect everyone to like this way of doing it, but there's no way
I'm going to peruse docs just to find out if there is something
super-duper on the shelf.
