#luvit-set

Straightforward [Lua](http://www.lua.org/) Set library for [Luvit](http://luvit.io/)

##Install

- Download and install [Node.js](http://nodejs.org/download/). Then you have `npm`

- In the root of your Luvit project, `npm install luvit-set`

##Usage

Start off with

```lua

local Set = require("luvit-set")

```

Then, to create a set (of things you like):

```lua

local ilike = Set:new()

```

to add items to a set:

```lua

ilike:add("apples")

ilike:add("bananas")

```

or, initialise with values on creation:

```lua

local ilike = Set:new({"apples", "bananas"})

```

Let's create another set:

```lua

local ulike = Set:new({"apples", "strawberries"})

```

Then we can:

```lua

local welike     = ilike + ulike -- union:        apples, bananas, strawberries

local webothlike = ilike * ulike -- intersection: apples

local udontlike  = ilike - ulike -- subtraction:  bananas

```

Lastly, some conveniences:

```lua

local somethingilike = ilike:anelement()

ilike:len()  -- 2

for k, _ in pairs(ilike) do

  print(k)

end

print(ilike) -- '{"apples", "bananas"}'

local list = ilike:tolist() -- {"apples", "bananas"}

```
