[![GoDoc](https://godoc.org/github.com/andygrunwald/go-jira?status.svg)](https://godoc.org/github.com/andygrunwald/go-jira)
[![Build Status](https://travis-ci.org/andygrunwald/go-jira.svg?branch=master)](https://travis-ci.org/andygrunwald/go-jira)
[![Go Report Card](https://goreportcard.com/badge/github.com/andygrunwald/go-jira)](https://goreportcard.com/report/github.com/andygrunwald/go-jira)
[Go](https://golang.org/) client library for [Atlassian JIRA](https://www.atlassian.com/software/jira).
![Go client library for Atlassian JIRA](./img/logo_small.png "Go client library for Atlassian JIRA.")
## Features
* Authentication (HTTP Basic, OAuth, Session Cookie)
* Create and retrieve issues
* Create and retrieve issue transitions (status updates)
* Call every API endpoint of the JIRA, even if it is not directly implemented in this library
This package is not JIRA API complete (yet), but you can call every API endpoint you want. See [Call a not implemented API endpoint](#call-a-not-implemented-api-endpoint) how to do this. For all possible API endpoints of JIRA have a look at [latest JIRA REST API documentation](https://docs.atlassian.com/jira/REST/latest/).
## Compatible JIRA versions
This package was tested against JIRA v6.3.4 and v7.1.2.
## Installation
It is go gettable
$ go get github.com/andygrunwald/go-jira
For stable versions you can use one of our tags with [gopkg.in](http://labix.org/gopkg.in). E.g.
```go
package main
import (
jira "gopkg.in/andygrunwald/go-jira.v1"
)
...
```
(optional) to run unit / example tests:
$ cd $GOPATH/src/github.com/andygrunwald/go-jira
$ go test -v ./...
## API
Please have a look at the [GoDoc documentation](https://godoc.org/github.com/andygrunwald/go-jira) for a detailed API description.
The [latest JIRA REST API documentation](https://docs.atlassian.com/jira/REST/latest/) was the base document for this package.
## Examples
Further a few examples how the API can be used.
A few more examples are available in the [GoDoc examples section](https://godoc.org/github.com/andygrunwald/go-jira#pkg-examples).
### Get a single issue
Lets retrieve [MESOS-3325](https://issues.apache.org/jira/browse/MESOS-3325) from the [Apache Mesos](http://mesos.apache.org/) project.
```go
package main
import (
"fmt"
"github.com/andygrunwald/go-jira"
)
func main() {
jiraClient, _ := jira.NewClient(nil, "https://issues.apache.org/jira/")
issue, _, _ := jiraClient.Issue.Get("MESOS-3325", nil)
fmt.Printf("%s: %+v\n", issue.Key, issue.Fields.Summary)
fmt.Printf("Type: %s\n", issue.Fields.Type.Name)
fmt.Printf("Priority: %s\n", issue.Fields.Priority.Name)
// MESOS-3325: Running mesos-slave@0.23 in a container causes slave to be lost after a restart
// Type: Bug
// Priority: Critical
}
```
### Authentication
The `go-jira` library does not handle most authentication directly. Instead, authentication should be handled within
an `http.Client`. That client can then be passed into the `NewClient` function when creating a jira client.
For convenience, capability for basic and cookie-based authentication is included in the main library.
#### Basic auth example
A more thorough, [runnable example](examples/basicauth/main.go) is provided in the examples directory.
```go
func main() {
tp := jira.BasicAuthTransport{
Username: "username",
Password: "password",
}
client, err := jira.NewClient(tp.Client(), "https://my.jira.com")
u, _, err := client.User.Get("some_user")
fmt.Printf("\nEmail: %v\nSuccess!\n", u.EmailAddress)
}
```
#### Authenticate with session cookie
A more thorough, [runnable example](examples/cookieauth/main.go) is provided in the examples directory.
Note: The `AuthURL` is almost always going to have the path `/rest/auth/1/session`
```go
tp := jira.CookieAuthTransport{
Username: "username",
Password: "password",
AuthURL: "https://my.jira.com/rest/auth/1/session",
}
client, err := jira.NewClient(tp.Client(), "https://my.jira.com")
u, _, err := client.User.Get("admin")
fmt.Printf("\nEmail: %v\nSuccess!\n", u.EmailAddress)
}
```
#### Authenticate with OAuth
If you want to connect via OAuth to your JIRA Cloud instance checkout the [example of using OAuth authentication with JIRA in Go](https://gist.github.com/Lupus/edafe9a7c5c6b13407293d795442fe67) by [@Lupus](https://github.com/Lupus).
For more details have a look at the [issue #56](https://github.com/andygrunwald/go-jira/issues/56).
### Create an issue
Example how to create an issue.
```go
package main
import (
"fmt"
"github.com/andygrunwald/go-jira"
)
func main() {
base := "https://my.jira.com"
tp := jira.CookieAuthTransport{
Username: "username",
Password: "password",
AuthURL: fmt.Sprintf("%s/rest/auth/1/session", base),
}
jiraClient, err := jira.NewClient(tp.Client(), base)
if err != nil {
panic(err)
}
i := jira.Issue{
Fields: &jira.IssueFields{
Assignee: &jira.User{
Name: "myuser",
},
Reporter: &jira.User{
Name: "youruser",
},
Description: "Test Issue",
Type: jira.IssueType{
Name: "Bug",
},
Project: jira.Project{
Key: "PROJ1",
},
Summary: "Just a demo issue",
},
}
issue, _, err := jiraClient.Issue.Create(&i)
if err != nil {
panic(err)
}
fmt.Printf("%s: %+v\n", issue.Key, issue.Fields.Summary)
}
```
### Call a not implemented API endpoint
Not all API endpoints of the JIRA API are implemented into *go-jira*.
But you can call them anyway:
Lets get all public projects of [Atlassian`s JIRA instance](https://jira.atlassian.com/).
```go
package main
import (
"fmt"
"github.com/andygrunwald/go-jira"
)
func main() {
base := "https://my.jira.com"
tp := jira.CookieAuthTransport{
Username: "username",
Password: "password",
AuthURL: fmt.Sprintf("%s/rest/auth/1/session", base),
}
jiraClient, err := jira.NewClient(tp.Client(), base)
req, _ := jiraClient.NewRequest("GET", "/rest/api/2/project", nil)
projects := new([]jira.Project)
_, err := jiraClient.Do(req, projects)
if err != nil {
panic(err)
}
for _, project := range *projects {
fmt.Printf("%s: %s\n", project.Key, project.Name)
}
// ...
// BAM: Bamboo
// BAMJ: Bamboo JIRA Plugin
// CLOV: Clover
// CONF: Confluence
// ...
}
```
## Implementations
* [andygrunwald/jitic](https://github.com/andygrunwald/jitic) - The JIRA Ticket Checker
## Code structure
The code structure of this package was inspired by [google/go-github](https://github.com/google/go-github).
There is one main part (the client).
Based on this main client the other endpoints, like Issues or Authentication are extracted in services. E.g. `IssueService` or `AuthenticationService`.
These services own a responsibility of the single endpoints / usecases of JIRA.
## Contribution
Contribution, in any kind of way, is highly welcome!
It doesn't matter if you are not able to write code.
Creating issues or holding talks and help other people to use [go-jira](https://github.com/andygrunwald/go-jira) is contribution, too!
A few examples:
* Correct typos in the README / documentation
* Reporting bugs
* Implement a new feature or endpoint
* Sharing the love if [go-jira](https://github.com/andygrunwald/go-jira) and help people to get use to it
If you are new to pull requests, checkout [Collaborating on projects using issues and pull requests / Creating a pull request](https://help.github.com/articles/creating-a-pull-request/).
### Dependency management
`go-jira` uses `dep` for dependency management. After cloning the repo, it's easy to make sure you have the correct dependencies by running `dep ensure`.
For adding new dependencies, updating dependencies, and other operations, the [Daily Dep](https://golang.github.io/dep/docs/daily-dep.html) is a good place to start.
### Sandbox environment for testing
Jira offers sandbox test environments at http://go.atlassian.com/cloud-dev.
You can read more about them at https://developer.atlassian.com/blog/2016/04/cloud-ecosystem-dev-env/.

# Structs [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/fatih/structs) [![Build Status](http://img.shields.io/travis/fatih/structs.svg?style=flat-square)](https://travis-ci.org/fatih/structs) [![Coverage Status](http://img.shields.io/coveralls/fatih/structs.svg?style=flat-square)](https://coveralls.io/r/fatih/structs)
Structs contains various utilities to work with Go (Golang) structs. It was
initially used by me to convert a struct into a `map[string]interface{}`. With
time I've added other utilities for structs. It's basically a high level
package based on primitives from the reflect package. Feel free to add new
functions or improve the existing code.
## Install
```bash
go get github.com/fatih/structs
```
## Usage and Examples
Just like the standard lib `strings`, `bytes` and co packages, `structs` has
many global functions to manipulate or organize your struct data. Lets define
and declare a struct:
```go
type Server struct {
Name string `json:"name,omitempty"`
ID int
Enabled bool
users []string // not exported
http.Server // embedded
}
server := &Server{
Name: "gopher",
ID: 123456,
Enabled: true,
}
```
```go
// Convert a struct to a map[string]interface{}
// => {"Name":"gopher", "ID":123456, "Enabled":true}
m := structs.Map(server)
// Convert the values of a struct to a []interface{}
// => ["gopher", 123456, true]
v := structs.Values(server)
// Convert the names of a struct to a []string
// (see "Names methods" for more info about fields)
n := structs.Names(server)
// Convert the values of a struct to a []*Field
// (see "Field methods" for more info about fields)
f := structs.Fields(server)
// Return the struct name => "Server"
n := structs.Name(server)
// Check if any field of a struct is initialized or not.
h := structs.HasZero(server)
// Check if all fields of a struct is initialized or not.
z := structs.IsZero(server)
// Check if server is a struct or a pointer to struct
i := structs.IsStruct(server)
```
### Struct methods
The structs functions can be also used as independent methods by creating a new
`*structs.Struct`. This is handy if you want to have more control over the
structs (such as retrieving a single Field).
```go
// Create a new struct type:
s := structs.New(server)
m := s.Map() // Get a map[string]interface{}
v := s.Values() // Get a []interface{}
f := s.Fields() // Get a []*Field
n := s.Names() // Get a []string
f := s.Field(name) // Get a *Field based on the given field name
f, ok := s.FieldOk(name) // Get a *Field based on the given field name
n := s.Name() // Get the struct name
h := s.HasZero() // Check if any field is initialized
z := s.IsZero() // Check if all fields are initialized
```
### Field methods
We can easily examine a single Field for more detail. Below you can see how we
get and interact with various field methods:
```go
s := structs.New(server)
// Get the Field struct for the "Name" field
name := s.Field("Name")
// Get the underlying value, value => "gopher"
value := name.Value().(string)
// Set the field's value
name.Set("another gopher")
// Get the field's kind, kind => "string"
name.Kind()
// Check if the field is exported or not
if name.IsExported() {
fmt.Println("Name field is exported")
}
// Check if the value is a zero value, such as "" for string, 0 for int
if !name.IsZero() {
fmt.Println("Name is initialized")
}
// Check if the field is an anonymous (embedded) field
if !name.IsEmbedded() {
fmt.Println("Name is not an embedded field")
}
// Get the Field's tag value for tag name "json", tag value => "name,omitempty"
tagValue := name.Tag("json")
```
Nested structs are supported too:
```go
addrField := s.Field("Server").Field("Addr")
// Get the value for addr
a := addrField.Value().(string)
// Or get all fields
httpServer := s.Field("Server").Fields()
```
We can also get a slice of Fields from the Struct type to iterate over all
fields. This is handy if you wish to examine all fields:
```go
s := structs.New(server)
for _, f := range s.Fields() {
fmt.Printf("field name: %+v\n", f.Name())
if f.IsExported() {
fmt.Printf("value : %+v\n", f.Value())
fmt.Printf("is zero : %+v\n", f.IsZero())
}
}
```
