A Tezos Go Library

Go Tezos is a GoLang driven library for your Tezos node.

Installation

Get goTezos

go get github.com/DefinitelyNotAGoat/go-tezos

Quick Start

Go Tezos is split into multiple services underneath to help organize it's functionality and also makes the library easier to maintain.

To understand how Go Tezos works, take a look at the GoTezos Structure:

type GoTezos struct {
	client    *client
	Constants NetworkConstants
	Block     *BlockService
	SnapShot  *SnapShotService
	Cycle     *CycleService
	Account   *AccountService
	Delegate  *DelegateService
	Network   *NetworkService
	Operation *OperationService
	Contract  *ContractService
}

You can see GoTezos is a wrapper for an http client, and services such as block, SnapShot, Cycle, Account, Delegate, Network, Operation, and Contract. Each service has it's own set of functions. You can see examples of using the Block and SnapShot service below.

Getting A Block
package main

import (
	"fmt"
	goTezos "github.com/DefinitelyNotAGoat/go-tezos"
)

func main() {
	gt, err := goTezos.NewGoTezos("http://127.0.0.1:8732")
	if err != nil {
		fmt.Printf("could not connect to network: %v", err)
	}

	block, err := gt.Block.Get(1000)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(block)
}
Getting a Snap Shot For A Cycle
	snapshot, err := gt.SnapShot.Get(50)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(snapshot)

Note

Because this project is gaining some traction I made the decision to squash all commits into a single commit, so that we can have a clean and well organized commit history going forward. By doing that, the commit history doesn't reflect the contributions of some very helpful people apart of Tezos community and the go-tezos project. Please take a look at the pull request history to see their individual contributions.

Special Thank You

I want to make sure the following people are recognized and give a special thank you to some of the original contributers to go-tezos:

Pull Requests

Go Tezos is a relatively large project and has the potential to be larger, because of that it's important to maintain quality code and PR's. Please review the pull request guide lines here.
