# A set of useful extensions to Lua

[![Build Status](https://travis-ci.org/torch/xlua.svg)](https://travis-ci.org/torch/xlua) 

## Dependencies:
Torch7 (www.torch.ch)

## Install:
```
$ torch-rocks install xlua
```

## Use
```
$ torch -lxlua
xLua > a = 5
xLua > b = 'test'
xLua > xlua.who()

Global Libs:
{[1] = string,
 [2] = package,
 [3] = os,
 [4] = io,
 [5] = xlua,
 [6] = sys,
 [7] = math,
 [8] = debug,
 [9] = table,
 [10] = coroutine}

Global Vars:
{[a] = 5,
 [b] = test}

xLua > xlua.clearall()   -- also calls the garbage collector !
xLua > xlua.who()
