Overview

The hooks service provides a mechanism for creating tasks in response to events.

See:

How to use this package

First create a Hooks object: 

hooks := tchooks.New(nil)

and then call one or more of hooks's methods, e.g.: 

err := hooks.Ping(.....)

handling any errors... 

if err != nil {
	// handle error...
}

type Hooks 

type Hooks tcclient.Client

func New 

func New(credentials *tcclient.Credentials, rootURL string) *Hooks

New returns a Hooks client, configured to run against production. Pass in nil credentials to create a client without authentication. The returned client is mutable, so returned settings can be altered. 

hooks := tchooks.New(
    nil,                                      // client without authentication
    "http://localhost:1234/my/taskcluster",   // taskcluster hosted at this root URL on local machine

if err != nil {
	// handle errors...
}

func NewFromEnv

The credentials are taken from environment variables: 

TASKCLUSTER_CLIENT_ID
TASKCLUSTER_ACCESS_TOKEN
