GonormCypher

Neo4j Go library based on Anorm in the Play Framework.

Cypher is an amazing query language and I don't think that it should be abstracted away through incomplete "wrappers". This is my attempt at allowing you to use Cypher to interact with Neo4j in your Go code in a clean, idiomatic way.

Big ups to AnormCypher and Wes Freeman, as this is obviously a rough port of Wes' amazing work.

Installation

Use go get to install GonormCypher:

go get github.com/marpaia/GonormCypher

Unit tests

If you're testing this library on your local machine, just run go test -v, otherwise, edit gonorm_test.go and change http://localhost to whatever you'd like it to be, and then run go test -v.

External dependencies

This project has no external dependencies other than the Go standard library.

Documentation

Like most every other Golang project, this projects documentation can be found on godoc at godoc.org/github.com/marpaia/GonormCypher.

Examples

The unit tests are probably the best source of working examples for this project.

Consider the following example:

package main

import (
    "fmt"
    "github.com/marpaia/GonormCypher"
)

var g *gonorm.Gonorm

func init() {
    g = gonorm.New("http://localhost", 7474)
}

func main() {
    result, err := g.Cypher(`
    MERGE (p1:Person{name:{name1}})
    MERGE (p2:Person{name:{name2}})
    CREATE UNIQUE p1-[:KNOWS]->p2
    RETURN p1.name
    `).On(map[string]interface{}{
        "name1": "Alice",
        "name2": "Bob",
    }).Execute().AsString()

    if err != nil {
        panic(err)
    }

    fmt.Println("The result is:", result)
}

This will print The result is: Alice
