# Community

The Apache TinkerPop Community encompasses many different programming language ecosystems and, as a result, provides for helpful libraries, tools and applications for numerous environments and use cases. In this way, developers can feel comfortable programming in their language of choice. While TinkerPop provides official support for certain languages and tools, many are third-party supported by the wider TinkerPop Community.

Any listing of third-party products is intended to help users identify TinkerPop-enabled graph systems and does not constitute an endorsement by Apache TinkerPop nor the Apache Software Foundation. Please see the listing policy for information on how to get a TinkerPop-enabled product shown here.

Third-Party Libraries and Tools

- Ogre: Ogre is a Gremlin language variant for Clojure. It provides an API that enhances the expressivity of Gremlin within Clojure, it doesn't introduce any significant amount of performance overhead, and it can work with any TinkerPop-enabled graph database or analytic system.

##

Third-Party Libraries and Tools

- Gremlex: A Gremlin Server driver for Elixir.

##

Apache TinkerPop’s Gremlin-Go implements Gremlin for the Go programming language. It offers the features of the Gremlin language in a form familiar to Go developers.

    g := gremlingo.Traversal_().WithRemote(...)
    result, err := g.V().Out("knows").In("created").ToList()

Example

Third-Party Libraries and Tools

- Grammes: A strongly typed Gremlin server driver for Go.
- Gremgo: A Gremlin Server driver for Go.

##

Apache TinkerPop’s Gremlin-Groovy implements Gremlin within the Apache Groovy language. As a JVM-based language variant, Gremlin-Groovy is backed by Gremlin-Java constructs. Moreover, given its scripting nature, Gremlin-Groovy serves as the language of Gremlin Console and Gremlin Server.

    def g = traversal().withRemote(...)
    def l = g.V().out('knows').in('created').toList()

Example

`implementation 'org.apache.tinkerpop:gremlin-groovy:3.6.0'`

Third-Party Libraries and Tools

- greskell: Haskell binding for Gremlin graph query language.

##

Apache TinkerPop’s Gremlin-Java implements Gremlin within the Java language. It is considered the canonical, reference implementation of Gremlin and serves as the foundation by which all other Gremlin language variants should emulate.

    GraphTraversalSource g = traversal().withRemote(...);
    List l = g.V().out('knows').in('created').toList();

Example

    <!-- gremlin-driver is a common dependency but
         there are others -->
    <dependency>
      <groupId>org.apache.tinkerpop</groupId>
      <artifactId>gremlin-driver</artifactId>
      <version>3.6.0</version>
    </dependency>

Apache TinkerPop’s Gremlin-JavaScript implements Gremlin within the JavaScript language. It targets Node.js runtime.

    const g = traversal().withRemote(...);
    const l = await g.V().out('knows').in('created').toList();

Example

    npm install gremlin

npm

##

Apache TinkerPop’s Gremlin.NET implements Gremlin within the C# language making it easy for .NET developers to use Gremlin in their environment.

    var g = Traversal().WithRemote(...);
    var l = await g.V().Out("knows").In("created").ToList();

Example

    dotnet add package Gremlin.Net --version 3.6.0

Third-Party Libraries and Tools

- Gremlinq: A strongly typed server driver.

##

Apache TinkerPop’s gremlin-python implements Gremlin within the Python language. It attempts to make Gremlin feel Pythonic while adhering to Gremlin feel as much as possible.

    g = traversal().withRemote(...);
    l = g.V().both()[1:3].toList()

Example

    pip install gremlinpython

`docker pull tinkerpop/gremlin-console`
Gremlin Console

## Compilers and Transpilers

##

There are many languages built to query data. SQL is typically used to query relational data. There is SPARQL for RDF data. Cypher is used to do pattern matching in graph data. The list could go on. Compilers convert languages like these to Gremlin so that it becomes possible to use them in any context that Gremlin is used. In other words, a Gremlin Compiler enables a particular query language to work on any TinkerPop-enabled graph system.

- cypher-for-gremlin: A Cypher-to-Gremlin traversal transpiler.
- sparql-gremlin: A SPARQL to Gremlin traversal compiler.
- sql-gremlin: A SQL to Gremlin traversal compiler.
