This repository is currently unmaintained, please do not use it for new projects. You may be interested in @shuheiktgw's fork, which has been updated to use the Travis v3 API. It is available here: https://github.com/shuheiktgw/go-travis.

go-travis

go-travis is a Go client library for accessing the Travis CI API.

Documentation:

go-travis requires Go version 1.1 or greater.

Dive

import (
    "log"
    travis "github.com/Ableton/go-travis"
)

client := travis.NewDefaultClient("")
builds, _, _, resp, err := client.Builds.ListFromRepository("Ableton/go-travis", nil)
if err != nil {
    log.Fatal(err)
}

// Now do something with the builds

Installation

$ go get github.com/Ableton/go-travis

Usage

Interaction with the Travis CI API is done through a Client instance.

import travis "github.com/Ableton/go-travis"

client := travis.NewClient(travis.TRAVIS_API_DEFAULT_URL, "asuperdupertoken")

Constructing it with the NewClient helper requires two arguments:

• The Travis CI API URL you wish to communicate with. Different Travis CI plans are accessed through different URLs. go-travis exposes constants for these URLs:
  • TRAVIS_API_DEFAULT_URL: default api.travis-ci.org endpoint for the free Travis "Open Source" plan.
  • TRAVIS_API_PRO_URL: the api.travis-ci.com endpoint for the paid Travis pro plans.
• A Travis CI token with which to authenticate. If you wish to run requests unauthenticated, pass an empty string. It is possible at any time to authenticate the Client instance with a Travis token or a Github token. For more information see Authentication.

Services oriented design

The Client instance's Service attributes provide access to Travis CI API resources.

opt := &travis.BuildListOptions{EventType: "pull request"}
builds, response, err := client.Builds.ListFromRepository("mygithubuser/mygithubrepo", opt)
if err != nil {
        log.Fatal(err)
}

Non exhaustive list of implemented services:

• Authentication
• Branches
• Builds
• Commits
• Jobs
• Logs
• Repositories
• Requests
• Users

(For an up to date exhaustive list, please check out the documentation)

Nota: Service methods will often take an Option (sub-)type instance as input. These types, like BuildListOptions allow narrowing and filtering your requests.

Authentication

The Client instance supports both authenticated and unauthenticated interaction with the Travis CI API. Note that both Pro and Enterprise plans will require almost all API calls to be authenticated.

Unuathenticated

It is possible to use the client unauthenticated. However some resources won't be accesible.

unauthClient := travis.NewClient(travis.TRAVIS_API_DEFAULT_URL, "")
builds, _, _, resp, err := unauthClient.Builds.ListFromRepository("mygithubuser/myopensourceproject", nil)
// Do something with your builds

_, err := unauthClient.Jobs.Cancel(12345)
if err != nil {
        // This operation is unavailable in unauthenticated mode and will
        // throw an error.
}

Authenticated

The Client instance supports authentication with both Travis token and Github token.

authClient := travis.NewClient(travis.TRAVIS_API_DEFAULT_URL, "mytravistoken")
builds, _, _, resp, err := authClient.Builds.ListFromRepository("mygithubuser/myopensourceproject",
nil)
// Do something with your builds

_, err := unauthClient.Jobs.Cancel(12345)
// Your job is succesfully canceled

However, authentication with a Github token will require and extra step (and request).

authWithGithubClient := travis.NewClient(travis.TRAVIS_API_DEFAULT_URL, "")
// authWithGithubClient.IsAuthenticated() will return false

err := authWithGithubClient.Authentication.UsingGithubToken("mygithubtoken")
if err != nil {
        log.Fatal(err)
}
// authWithGithubClient.IsAuthenticated()  will return true

builds, _, _, resp, err := authClient.Builds.ListFromRepository("mygithubuser/myopensourceproject",
nil)
// Do something with your builds

Pagination

The services support resource pagination through the ListOption type. Every services Option type implements the ListOption type.

client := travis.NewClient(travis.TRAVIS_API_DEFAULT_URL, "mysuperdupertoken")
opt := &travis.BuildListOptions{}

for {
        travisBuilds, _, _, _, err := tc.Builds.ListFromRepository(target, opt)
        if err != nil {
                log.Fatal(err)
        }

        // Do something with the builds

        opt.GetNextPage(travisBuilds)
        if opt.AfterNumber <= 1 {  // Travis CI resources are one-indexed (not zero-indexed)
                break
        }
}
