2.2 小精灵控制台 The Gremlin console 实用的小精灵（Gremlin图查询语言） 阿岶奇TinkerPop向导 PRACTICAL GREMLIN An Apache TinkerPop Tutorial

小精灵控制台是一个相当标准的交互式解释器（读到-求值-输出循环）Shell。它是基于Groovy 控制台的，如果您已经使用过一些其它的控制台环境，例如Scala, Python或者Ruby的控制台，您会觉得得心应手。控制台提供了低开销（仅需几秒就启动）和低准入，您可以在自己本地的电脑上开始探索图数据库的乐趣。事实上，控制台可以与本地或者远程的图数据库一起工作，但是在本书中为了让内容尽可能的简单，我们重点关注的是本地的图数据库。

The Gremlin Console is a fairly standard REPL (Read Eval Print Loop) shell. It is based on the

Groovy console and if you have used any of the other console environments such as those found

with Scala, Python and Ruby you will feel right at home here. The Console offers a low overhead

(you can set it up in seconds) and low barrier of entry way to start to play with graphs on your local

computer. The console can actually work with graphs that are running locally or remotely but for

the majority of this book we will keep things simple and focus on local graphs.

为了更好的跟随本入门向导，您需要安装小精灵控制台，或者访问支持TinkerPop3/小精灵的图存储，例如廷克图TinkerGraph或者杰森图JanusGraph

To follow along with this tutorial you will need to have installed the Gremlin console or have access

to a TinkerPop3/Gremlin enabled graph store such as TinkerGraph or JanusGraph.

无论您使用哪种环境，如果您要在支持阿岶奇TinkerPop的图存储上工作，您就得在您的机器上安装小精灵控制台。

Regardless of the environment you use, if you work with Apache TinkerPop enabled graphs, the

Gremlin console should always be installed on your machine!
