# quotedprintable
## Introduction
Package quotedprintable implements quoted-printable and message header encoding
as specified by RFC 2045 and RFC 2047.
It is a copy of the Go 1.5 package `mime/quotedprintable`. It also includes
the new functions of package `mime` concerning RFC 2047.
This code has minor changes with the standard library code in order to work
with Go 1.0 and newer.

Package validator implements value validations for structs and individual fields based on tags.
It has the following **unique** features:
- Cross Field and Cross Struct validations by using validation tags or custom validators.
- Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated.
- Ability to dive into both map keys and values for validation
- Handles type interface by determining it's underlying type prior to validation.
- Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29)
- Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs
- Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError
- Customizable i18n aware error messages.
- Default validator for the [gin](https://github.com/gin-gonic/gin) web framework; upgrading from v8 to v9 in gin see [here](https://github.com/go-playground/validator/tree/v9/_examples/gin-upgrading-overriding)
Installation
------------
Use go get.
go get gopkg.in/go-playground/validator.v9
Then import the validator package into your own code.
import "gopkg.in/go-playground/validator.v9"
Error Return Value
-------
Validation functions return type error
They return type error to avoid the issue discussed in the following, where err is always != nil:
* http://stackoverflow.com/a/29138676/3158232
* https://github.com/go-playground/validator/issues/134
Validator only InvalidValidationError for bad validation input, nil or ValidationErrors as type error; so, in your code all you need to do is check if the error returned is not nil, and if it's not check if error is InvalidValidationError ( if necessary, most of the time it isn't ) type cast it to type ValidationErrors like so:
```go
err := validate.Struct(mystruct)
validationErrors := err.(validator.ValidationErrors)
```

/*
Package validator implements value validations for structs and individual fields
based on tags.
It can also handle Cross-Field and Cross-Struct validation for nested structs
and has the ability to dive into arrays and maps of any type.
see more examples https://github.com/go-playground/validator/tree/v9/_examples
Validation Functions Return Type error
Doing things this way is actually the way the standard library does, see the
file.Open method here:
https://golang.org/pkg/os/#Open.
The authors return type "error" to avoid the issue discussed in the following,
where err is always != nil:
http://stackoverflow.com/a/29138676/3158232
https://github.com/go-playground/validator/issues/134
Validator only InvalidValidationError for bad validation input, nil or
ValidationErrors as type error; so, in your code all you need to do is check
if the error returned is not nil, and if it's not check if error is
InvalidValidationError ( if necessary, most of the time it isn't ) type cast
it to type ValidationErrors like so err.(validator.ValidationErrors).
Custom Validation Functions
Custom Validation functions can be added. Example:
// Structure
func customFunc(fl FieldLevel) bool {
if fl.Field().String() == "invalid" {
return false
}
return true
}
validate.RegisterValidation("custom tag name", customFunc)
// NOTES: using the same tag name as an existing function
// will overwrite the existing one
Cross-Field Validation
Cross-Field Validation can be done via the following tags:
- eqfield
- nefield
- gtfield
- gtefield
- ltfield
- ltefield
- eqcsfield
- necsfield
- gtcsfield
- gtecsfield
- ltcsfield
- ltecsfield
If, however, some custom cross-field validation is required, it can be done
using a custom validation.
Why not just have cross-fields validation tags (i.e. only eqcsfield and not
eqfield)?
The reason is efficiency. If you want to check a field within the same struct
"eqfield" only has to find the field on the same struct (1 level). But, if we
used "eqcsfield" it could be multiple levels down. Example:
type Inner struct {
StartDate time.Time
}
type Outer struct {
InnerStructField *Inner
CreatedAt time.Time `validate:"ltecsfield=InnerStructField.StartDate"`
}
now := time.Now()
inner := &Inner{
StartDate: now,
}
outer := &Outer{
InnerStructField: inner,
CreatedAt: now,
}
errs := validate.Struct(outer)
// NOTE: when calling validate.Struct(val) topStruct will be the top level struct passed
// into the function
// when calling validate.FieldWithValue(val, field, tag) val will be
// whatever you pass, struct, field...
// when calling validate.Field(field, tag) val will be nil
Multiple Validators
Multiple validators on a field will process in the order defined. Example:
type Test struct {
Field `validate:"max=10,min=1"`
}
// max will be checked then min
Bad Validator definitions are not handled by the library. Example:
type Test struct {
Field `validate:"min=10,max=0"`
}
// this definition of min max will never succeed
Using Validator Tags
Baked In Cross-Field validation only compares fields on the same struct.
If Cross-Field + Cross-Struct validation is needed you should implement your
own custom validator.
Comma (",") is the default separator of validation tags. If you wish to
have a comma included within the parameter (i.e. excludesall=,) you will need to
use the UTF-8 hex representation 0x2C, which is replaced in the code as a comma,
so the above will become excludesall=0x2C.
type Test struct {
Field `validate:"excludesall=,"` // BAD! Do not include a comma.
Field `validate:"excludesall=0x2C"` // GOOD! Use the UTF-8 hex representation.
}
Pipe ("|") is the default separator of validation tags. If you wish to
have a pipe included within the parameter i.e. excludesall=| you will need to
use the UTF-8 hex representation 0x7C, which is replaced in the code as a pipe,
so the above will become excludesall=0x7C
type Test struct {
Field `validate:"excludesall=|"` // BAD! Do not include a a pipe!
Field `validate:"excludesall=0x7C"` // GOOD! Use the UTF-8 hex representation.
}
Baked In Validators and Tags
Here is a list of the current built in validators:
Skip Field
Tells the validation to skip this struct field; this is particularly
handy in ignoring embedded structs from being validated. (Usage: -)
Usage: -
Or Operator
This is the 'or' operator allowing multiple validators to be used and
accepted. (Usage: rbg|rgba) <-- this would allow either rgb or rgba
colors to be accepted. This can also be combined with 'and' for example
( Usage: omitempty,rgb|rgba)
Usage: |
StructOnly
When a field that is a nested struct is encountered, and contains this flag
any validation on the nested struct will be run, but none of the nested
struct fields will be validated. This is usefull if inside of you program
you know the struct will be valid, but need to verify it has been assigned.
NOTE: only "required" and "omitempty" can be used on a struct itself.
Usage: structonly
NoStructLevel
Same as structonly tag except that any struct level validations will not run.
Usage: nostructlevel
Omit Empty
Allows conditional validation, for example if a field is not set with
a value (Determined by the "required" validator) then other validation
such as min or max won't run, but if a value is set validation will run.
Usage: omitempty
Dive
This tells the validator to dive into a slice, array or map and validate that
level of the slice, array or map with the validation tags that follow.
Multidimensional nesting is also supported, each level you wish to dive will
require another dive tag. dive has some sub-tags, 'keys' & 'endkeys', please see
the Keys & EndKeys section just below.
Usage: dive
Example #1
[][]string with validation tag "gt=0,dive,len=1,dive,required"
// gt=0 will be applied to []
// len=1 will be applied to []string
// required will be applied to string
Example #2
[][]string with validation tag "gt=0,dive,dive,required"
// gt=0 will be applied to []
// []string will be spared validation
// required will be applied to string
Keys & EndKeys
These are to be used together directly after the dive tag and tells the validator
that anything between 'keys' and 'endkeys' applies to the keys of a map and not the
values; think of it like the 'dive' tag, but for map keys instead of values.
Multidimensional nesting is also supported, each level you wish to validate will
require another 'keys' and 'endkeys' tag. These tags are only valid for maps.
Usage: dive,keys,othertagvalidation(s),endkeys,valuevalidationtags
Example #1
map[string]string with validation tag "gt=0,dive,keys,eg=1|eq=2,endkeys,required"
// gt=0 will be applied to the map itself
// eg=1|eq=2 will be applied to the map keys
// required will be applied to map values
Example #2
map[[2]string]string with validation tag "gt=0,dive,keys,dive,eq=1|eq=2,endkeys,required"
// gt=0 will be applied to the map itself
// eg=1|eq=2 will be applied to each array element in the the map keys
// required will be applied to map values
Required
This validates that the value is not the data types default zero value.
For numbers ensures value is not zero. For strings ensures value is
not "". For slices, maps, pointers, interfaces, channels and functions
ensures the value is not nil.
Usage: required
Is Default
This validates that the value is the default value and is almost the
opposite of required.
Usage: isdefault
Length
For numbers, length will ensure that the value is
equal to the parameter given. For strings, it checks that
the string length is exactly that number of characters. For slices,
arrays, and maps, validates the number of items.
Usage: len=10
Maximum
For numbers, max will ensure that the value is
less than or equal to the parameter given. For strings, it checks
that the string length is at most that number of characters. For
slices, arrays, and maps, validates the number of items.
Usage: max=10
Minimum
For numbers, min will ensure that the value is
greater or equal to the parameter given. For strings, it checks that
the string length is at least that number of characters. For slices,
arrays, and maps, validates the number of items.
Usage: min=10
Equals
For strings & numbers, eq will ensure that the value is
equal to the parameter given. For slices, arrays, and maps,
validates the number of items.
Usage: eq=10
Not Equal
For strings & numbers, ne will ensure that the value is not
equal to the parameter given. For slices, arrays, and maps,
validates the number of items.
Usage: ne=10
Greater Than
For numbers, this will ensure that the value is greater than the
parameter given. For strings, it checks that the string length
is greater than that number of characters. For slices, arrays
and maps it validates the number of items.
Example #1
Usage: gt=10
Example #2 (time.Time)
For time.Time ensures the time value is greater than time.Now.UTC().
Usage: gt
Greater Than or Equal
Same as 'min' above. Kept both to make terminology with 'len' easier.
Example #1
Usage: gte=10
Example #2 (time.Time)
For time.Time ensures the time value is greater than or equal to time.Now.UTC().
Usage: gte

For numbers, this will ensure that the value is less than the parameter given.
For strings, it checks that the string length is less than that number of
characters. For slices, arrays, and maps it validates the number of items.
Example #1
Usage: lt=10
Example #2 (time.Time)
For time.Time ensures the time value is less than time.Now.UTC().
Usage: lt
Less Than or Equal
Same as 'max' above. Kept both to make terminology with 'len' easier.
Example #1
Usage: lte=10
Example #2 (time.Time)
For time.Time ensures the time value is less than or equal to time.Now.UTC().
Usage: lte
Field Equals Another Field
This will validate the field value against another fields value either within
a struct or passed in field.
Example #1:

a struct or passed in field.
Examples:
// Confirm two colors are not the same:
//
// Validation on Color field:
Usage: nefield=Color2
// Validating by field:
validate.FieldWithValue(color1, color2, "nefield")

Alias Validators and Tags
NOTE: When returning an error, the tag returned in "FieldError" will be
the alias tag unless the dive tag is part of the alias. Everything after the
dive tag is not reported as the alias tag. Also, the "ActualTag" in the before
case will be the actual tag within the alias that failed.
Here is a list of the current built in alias tags:
"iscolor"
alias is "hexcolor|rgb|rgba|hsl|hsla" (Usage: iscolor)
Validator notes:
regex
a regex validator won't be added because commas and = signs can be part
of a regex which conflict with the validation definitions. Although
workarounds can be made, they take away from using pure regex's.
Furthermore it's quick and dirty but the regex's become harder to
maintain and are not reusable, so it's as much a programming philosiphy
as anything.
In place of this new validator functions should be created; a regex can
be used within the validator function and even be precompiled for better
efficiency within regexes.go.
And the best reason, you can submit a pull request and we can keep on
adding to the validation library of this package!
Panics
This package panics when bad input is provided, this is by design, bad code like
that should not make it to production.
type Test struct {
TestField string `validate:"nonexistantfunction=1"`
}
t := &Test{
TestField: "Test"
}
validate.Struct(t) // this will panic

# Change Log
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## [2.0.0] - 2015-09-02
- Mailer has been removed. It has been replaced by Dialer and Sender.
- `File` type and the `CreateFile` and `OpenFile` functions have been removed.
- `Message.Attach` and `Message.Embed` have a new signature.
- `Message.GetBodyWriter` has been removed. Use `Message.AddAlternativeWriter`
instead.
- `Message.Export` has been removed. `Message.WriteTo` can be used instead.
- `Message.DelHeader` has been removed.
- The `Bcc` header field is no longer sent. It is far more simpler and
efficient: the same message is sent to all recipients instead of sending a
different email to each Bcc address.
- LoginAuth has been removed. `NewPlainDialer` now implements the LOGIN
authentication mechanism when needed.
- Go 1.2 is now required instead of Go 1.3. No external dependency are used when
using Go 1.5.

Thank you for contributing to Gomail! Here are a few guidelines:
## Bugs
If you think you found a bug, create an issue and supply the minimum amount
of code triggering the bug so it can be reproduced.
## Fixing a bug
If you want to fix a bug, you can send a pull request. It should contains a
new test or update an existing one to cover that bug.
## New feature proposal
If you think Gomail lacks a feature, you can open an issue or send a pull
request. I want to keep Gomail code and API as simple as possible so please
describe your needs so we can discuss whether this feature should be added to
Gomail or not.

# Gomail
[![Build Status](https://travis-ci.org/go-gomail/gomail.svg?branch=v2)](https://travis-ci.org/go-gomail/gomail) [![Code Coverage](http://gocover.io/_badge/gopkg.in/gomail.v2)](http://gocover.io/gopkg.in/gomail.v2) [![Documentation](https://godoc.org/gopkg.in/gomail.v2?status.svg)](https://godoc.org/gopkg.in/gomail.v2)
## Introduction
Gomail is a simple and efficient package to send emails. It is well tested and
documented.
Gomail can only send emails using an SMTP server. But the API is flexible and it
is easy to implement other methods for sending emails using a local Postfix, an
API, etc.
It is versioned using [gopkg.in](https://gopkg.in) so I promise
there will never be backward incompatible changes within each version.
It requires Go 1.2 or newer. With Go 1.5, no external dependencies are used.
## Features
Gomail supports:
- Attachments
- Embedded images
- HTML and text templates
- Automatic encoding of special characters
- SSL and TLS
- Sending multiple emails with the same SMTP connection
## Documentation
https://godoc.org/gopkg.in/gomail.v2
## Download
go get gopkg.in/gomail.v2
## Examples
See the [examples in the documentation](https://godoc.org/gopkg.in/gomail.v2#example-package).
## FAQ
### x509: certificate signed by unknown authority
If you get this error it means the certificate used by the SMTP server is not
considered valid by the client running Gomail. As a quick workaround you can
bypass the verification of the server's certificate chain and host name by using
`SetTLSConfig`:
package main
import (
"crypto/tls"
"gopkg.in/gomail.v2"
)
func main() {
d := gomail.NewDialer("smtp.example.com", 587, "user", "123456")
d.TLSConfig = &tls.Config{InsecureSkipVerify: true}
// Send emails using d.
}
Note, however, that this is insecure and should not be used in production.

# gock [![Build Status](https://travis-ci.org/h2non/gock.svg?branch=master)](https://travis-ci.org/h2non/gock) [![GitHub release](https://img.shields.io/badge/version-v1.0-orange.svg?style=flat)](https://github.com/h2non/gock/releases) [![GoDoc](https://godoc.org/github.com/h2non/gock?status.svg)](https://godoc.org/github.com/h2non/gock) [![Coverage Status](https://coveralls.io/repos/github/h2non/gock/badge.svg?branch=master)](https://coveralls.io/github/h2non/gock?branch=master) [![Go Report Card](https://img.shields.io/badge/go_report-A+-brightgreen.svg)](https://goreportcard.com/report/github.com/h2non/gock) [![license](https://img.shields.io/badge/license-MIT-blue.svg)]()
Versatile HTTP mocking made easy in [Go](https://golang.org).
Heavily inspired by [nock](https://github.com/node-nock/nock). See also its Python port, [pook](https://github.com/h2non/pook).
Take a look to the [examples](#examples) to get started.
## Features
- Simple, expressive, fluent API.
- Semantic DSL for easy HTTP mocks definition.
- Built-in helpers for easy JSON/XML mocking.
- Supports persistent and volatile mocks.
- Full regexp capable HTTP request matching.
- Designed for both testing and runtime scenarios.
- Match request by method, URL params, headers and bodies.
- Extensible and pluggable HTTP matching rules.
- Ability to switch between mock and real networking modes.
- Ability to filter/map HTTP requests for accurate mock matching.
- Supports map and filters to handle mocks easily.
- Wide compatible HTTP interceptor using `http.RoundTripper` interface.
- Works with any `net/http` compatible client, such as [gentleman](https://github.com/h2non/gentleman).
- Network delay simulation (beta).
- Extensible and hackable API.
- Dependency free.
## Installation
```bash
go get -u gopkg.in/h2non/gock.v1
```
## API
See [godoc reference](https://godoc.org/github.com/h2non/gock) for detailed API documentation.
## How it mocks
1. Intercepts any HTTP outgoing request via `http.DefaultTransport` or custom `http.Transport` used by any `http.Client`.
2. Matches outgoing HTTP requests against a pool of defined HTTP mock expectations in FIFO declaration order.
3. If at least one mock matches, it will be used in order to compose the mock HTTP response.
4. If no mock can be matched, it will resolve the request with an error, unless real networking mode is enable, in which case a real HTTP request will be performed.
## Tips
#### Testing
Declare your mocks before you start declaring the concrete test logic:
```go
func TestFoo(t *testing.T) {
defer gock.Off() // Flush pending mocks after test execution
gock.New("http://server.com").
Get("/bar").
Reply(200).
JSON(map[string]string{"foo": "bar"})
// Your test code starts here...
}
```
#### Race conditions
If you're running concurrent code, be aware that your mocks are declared first to avoid unexpected
race conditions while configuring `gock` or intercepting custom HTTP clients.
`gock` is not fully thread-safe, but sensible parts are. Any help making `gock` more reliable in this sense is highly appreciated.
#### Define complex mocks first
If you're mocking a bunch of mocks in the same test suite, it's recommended to define the more
concrete mocks first, and then the generic ones.
This approach usually avoids matching unexpected generic mocks (e.g: specific header, body payload...) instead of the generic ones that performs less complex matches.
## Examples
See [examples](https://github.com/h2non/gock/tree/master/_examples) directory for more featured use cases.
#### Simple mocking via tests
```go
package test
import (
"github.com/nbio/st"
"gopkg.in/h2non/gock.v1"
"io/ioutil"
"net/http"
"testing"
)
func TestSimple(t *testing.T) {
defer gock.Off()
gock.New("http://foo.com").
Get("/bar").
Reply(200).
JSON(map[string]string{"foo": "bar"})
res, err := http.Get("http://foo.com/bar")
st.Expect(t, err, nil)
st.Expect(t, res.StatusCode, 200)
body, _ := ioutil.ReadAll(res.Body)
st.Expect(t, string(body)[:13], `{"foo":"bar"}`)
// Verify that we don't have pending mocks
st.Expect(t, gock.IsDone(), true)
}
```
#### Request headers matching
```go
package test
import (
"github.com/nbio/st"
"gopkg.in/h2non/gock.v1"
"io/ioutil"
"net/http"
"testing"
)
func TestMatchHeaders(t *testing.T) {
defer gock.Off()
gock.New("http://foo.com").
MatchHeader("Authorization", "^foo bar$").
MatchHeader("API", "1.[0-9]+").
HeaderPresent("Accept").
Reply(200).
BodyString("foo foo")
req, err := http.NewRequest("GET", "http://foo.com", nil)
req.Header.Set("Authorization", "foo bar")
req.Header.Set("API", "1.0")
req.Header.Set("Accept", "text/plain")
res, err := (&http.Client{}).Do(req)
st.Expect(t, err, nil)
st.Expect(t, res.StatusCode, 200)
body, _ := ioutil.ReadAll(res.Body)
st.Expect(t, string(body), "foo foo")
// Verify that we don't have pending mocks
st.Expect(t, gock.IsDone(), true)
}
```
#### JSON body matching and response
```go
package test
import (
"bytes"
"github.com/nbio/st"
"gopkg.in/h2non/gock.v1"
"io/ioutil"
"net/http"
"testing"
)
func TestMockSimple(t *testing.T) {
defer gock.Off()
gock.New("http://foo.com").
Post("/bar").
MatchType("json").
JSON(map[string]string{"foo": "bar"}).
Reply(201).
JSON(map[string]string{"bar": "foo"})
body := bytes.NewBuffer([]byte(`{"foo":"bar"}`))
res, err := http.Post("http://foo.com/bar", "application/json", body)
st.Expect(t, err, nil)
st.Expect(t, res.StatusCode, 201)
resBody, _ := ioutil.ReadAll(res.Body)
st.Expect(t, string(resBody)[:13], `{"bar":"foo"}`)
// Verify that we don't have pending mocks
st.Expect(t, gock.IsDone(), true)
}
```
#### Mocking a custom http.Client and http.RoundTripper
```go
package test
import (
"github.com/nbio/st"
"gopkg.in/h2non/gock.v1"
"io/ioutil"
"net/http"
"testing"
)
func TestClient(t *testing.T) {
defer gock.Off()
gock.New("http://foo.com").
Reply(200).
BodyString("foo foo")
req, err := http.NewRequest("GET", "http://foo.com", nil)
client := &http.Client{Transport: &http.Transport{}}
gock.InterceptClient(client)
res, err := client.Do(req)
st.Expect(t, err, nil)
st.Expect(t, res.StatusCode, 200)
body, _ := ioutil.ReadAll(res.Body)
st.Expect(t, string(body), "foo foo")
// Verify that we don't have pending mocks
st.Expect(t, gock.IsDone(), true)
}
```
#### Enable real networking
```go
package main
import (
"fmt"
"gopkg.in/h2non/gock.v1"
"io/ioutil"
"net/http"
)
func main() {
defer gock.Off()
defer gock.DisableNetworking()
gock.EnableNetworking()
gock.New("http://httpbin.org").
Get("/get").
Reply(201).
SetHeader("Server", "gock")
res, err := http.Get("http://httpbin.org/get")
if err != nil {
fmt.Errorf("Error: %s", err)
}
// The response status comes from the mock
fmt.Printf("Status: %d\n", res.StatusCode)
// The server header comes from mock as well
fmt.Printf("Server header: %s\n", res.Header.Get("Server"))
// Response body is the original
body, _ := ioutil.ReadAll(res.Body)
fmt.Printf("Body: %s", string(body))
// Verify that we don't have pending mocks
st.Expect(t, gock.IsDone(), true)
}
```
## Hacking it!
You can easily hack `gock` defining custom matcher functions with own matching rules.
See [add matcher functions](https://github.com/h2non/gock/blob/master/_examples/add_matchers/matchers.go) and [custom matching layer](https://github.com/h2non/gock/blob/master/_examples/custom_matcher/matcher.go) examples for further details.

// Package inf (type inf.Dec) implements "infinite-precision" decimal
// arithmetic.
// "Infinite precision" describes two characteristics: practically unlimited
// precision for decimal number representation and no support for calculating
// with any specific fixed precision.
// (Although there is no practical limit on precision, inf.Dec can only
// represent finite decimals.)
//
// This package is currently in experimental stage and the API may change.
//
// This package does NOT support:
// - rounding to specific precisions (as opposed to specific decimal positions)
// - the notion of context (each rounding must be explicit)
// - NaN and Inf values, and distinguishing between positive and negative zero
// - conversions to and from float32/64 types
//
// Features considered for possible addition:
// + formatting options
// + Exp method
// + combined operations such as AddRound/MulAdd etc
// + exchanging data in decimal32/64/128 formats
//

// A Dec represents a signed arbitrary-precision decimal.
// It is a combination of a sign, an arbitrary-precision integer coefficient
// value, and a signed fixed-precision exponent value.
// The sign and the coefficient value are handled together as a signed value
// and referred to as the unscaled value.
// (Positive and negative zero values are not distinguished.)
// Since the exponent is most commonly non-positive, it is handled in negated
// form and referred to as scale.
//
// The mathematical value of a Dec equals:
//
// unscaled * 10**(-scale)
//
// Note that different Dec representations may have equal mathematical values.
//
// unscaled scale String()
// -------------------------
// 0 0 "0"
// 0 2 "0.00"
// 0 -2 "0"
// 1 0 "1"
// 100 2 "1.00"
// 10 0 "10"
// 1 -1 "10"
//
// The zero value for a Dec represents the value 0 with scale 0.
//
// Operations are typically performed through the *Dec type.
// The semantics of the assignment operation "=" for "bare" Dec values is
// undefined and should not be relied on.
//
// Methods are typically of the form:
//
// func (z *Dec) Op(x, y *Dec) *Dec
//
// and implement operations z = x Op y with the result as receiver; if it
// is one of the operands it may be overwritten (and its memory reused).
// To enable chaining of operations, the result is also returned. Methods
// returning a result other than *Dec take one of the operands as the receiver.
//
// A "bare" Quo method (quotient / division operation) is not provided, as the
// result is not always a finite decimal and thus in general cannot be
// represented as a Dec.
// Instead, in the common case when rounding is (potentially) necessary,
// QuoRound should be used with a Scale and a Rounder.
// QuoExact or QuoRound with RoundExact can be used in the special cases when it
// is known that the result is always a finite decimal.

# Elastic 3.0
Elasticsearch 2.0 comes with some [breaking changes](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/breaking-changes-2.0.html). You will probably need to upgrade your application and/or rewrite part of it due to those changes.
We use that window of opportunity to also update Elastic (the Go client) from version 2.0 to 3.0. This will introduce both changes due to the Elasticsearch 2.0 update as well as changes that make Elastic cleaner by removing some old cruft.
So, to summarize:
1. Elastic 2.0 is compatible with Elasticsearch 1.7+ and is still actively maintained.
2. Elastic 3.0 is compatible with Elasticsearch 2.0+ and will soon become the new master branch.
The rest of the document is a list of all changes in Elastic 3.0.
## Pointer types
All types have changed to be pointer types, not value types. This not only is cleaner but also simplifies the API as illustrated by the following example:
Example for Elastic 2.0 (old):
```go
q := elastic.NewMatchAllQuery()
res, err := elastic.Search("one").Query(&q).Do() // notice the & here
```
Example for Elastic 3.0 (new):
```go
q := elastic.NewMatchAllQuery()
res, err := elastic.Search("one").Query(q).Do() // no more &
// ... which can be simplified as:
res, err := elastic.Search("one").Query(elastic.NewMatchAllQuery()).Do()
```
It also helps to prevent [subtle issues](https://github.com/olivere/elastic/issues/115#issuecomment-130753046).
## Query/filter merge
One of the biggest changes in Elasticsearch 2.0 is the [merge of queries and filters](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_queries_and_filters_merged). In Elasticsearch 1.x, you had a whole range of queries and filters that were basically identical (e.g. `term_query` and `term_filter`).
The practical aspect of the merge is that you can now basically use queries where once you had to use filters instead. For Elastic 3.0 this means: We could remove a whole bunch of files. Yay!
Notice that some methods still come by "filter", e.g. `PostFilter`. However, they accept a `Query` now when they used to accept a `Filter` before.
Example for Elastic 2.0 (old):
```go
q := elastic.NewMatchAllQuery()
f := elastic.NewTermFilter("tag", "important")
res, err := elastic.Search().Index("one").Query(&q).PostFilter(f)
```
Example for Elastic 3.0 (new):
```go
q := elastic.NewMatchAllQuery()
f := elastic.NewTermQuery("tag", "important") // it's a query now!
res, err := elastic.Search().Index("one").Query(q).PostFilter(f)
```
## Facets are removed
[Facets have been removed](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_removed_features.html#_facets_have_been_removed) in Elasticsearch 2.0. You need to use aggregations now.
## Errors
Elasticsearch 2.0 returns more information about an error in the HTTP response body. Elastic 3.0 now reads this information and makes it accessible by the consumer.
Errors and all its details are now returned in [`Error`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L59).
### HTTP Status 404 (Not Found)
When Elasticsearch does not find an entity or an index, it generally returns HTTP status code 404. In Elastic 2.0 this was a valid result and didn't raise an error from the `Do` functions. This has now changed in Elastic 3.0.
Starting with Elastic 3.0, there are only two types of responses considered successful. First, responses with HTTP status codes [200..299]. Second, HEAD requests which return HTTP status 404. The latter is used by Elasticsearch to e.g. check for existence of indices or documents. All other responses will return an error.
To check for HTTP Status 404 (with non-HEAD requests), e.g. when trying to get or delete a missing document, you can use the [`IsNotFound`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L84) helper (see below).
The following example illustrates how to check for a missing document in Elastic 2.0 and what has changed in 3.0.
Example for Elastic 2.0 (old):
```go
res, err = client.Get().Index("one").Type("tweet").Id("no-such-id").Do()
if err != nil {
// Something else went wrong (but 404 is NOT an error in Elastic 2.0)
}
if !res.Found {
// Document has not been found
}
```
Example for Elastic 3.0 (new):
```go
res, err = client.Get().Index("one").Type("tweet").Id("no-such-id").Do()
if err != nil {
if elastic.IsNotFound(err) {
// Document has not been found
} else {
// Something else went wrong
}
}
```
### HTTP Status 408 (Timeouts)
Elasticsearch now responds with HTTP status code 408 (Timeout) when a request fails due to a timeout. E.g. if you specify a timeout with the Cluster Health API, the HTTP response status will be 408 if the timeout is raised. See [here](https://github.com/elastic/elasticsearch/commit/fe3179d9cccb569784434b2135ca9ae13d5158d3) for the specific commit to the Cluster Health API.
To check for HTTP Status 408, we introduced the [`IsTimeout`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L101) helper.
Example for Elastic 2.0 (old):
```go
health, err := client.ClusterHealth().WaitForStatus("yellow").Timeout("1s").Do()
if err != nil {
// ...
}
if health.TimedOut {
// We have a timeout
}
```
Example for Elastic 3.0 (new):
```go
health, err := client.ClusterHealth().WaitForStatus("yellow").Timeout("1s").Do()
if elastic.IsTimeout(err) {
// We have a timeout
}
```
### Bulk Errors
The error response of a bulk operation used to be a simple string in Elasticsearch 1.x.
In Elasticsearch 2.0, it returns a structured JSON object with a lot more details about the error.
These errors are now captured in an object of type [`ErrorDetails`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L59) which is used in [`BulkResponseItem`](https://github.com/olivere/elastic/blob/release-branch.v3/bulk.go#L206).
### Removed specific Elastic errors
The specific error types `ErrMissingIndex`, `ErrMissingType`, and `ErrMissingId` have been removed. They were only used by `DeleteService` and are replaced by a generic error message.
## Numeric types
Elastic 3.0 has settled to use `float64` everywhere. It used to be a mix of `float32` and `float64` in Elastic 2.0. E.g. all boostable queries in Elastic 3.0 now have a boost type of `float64` where it used to be `float32`.
## Pluralization
Some services accept zero, one or more indices or types to operate on.
E.g. in the `SearchService` accepts a list of zero, one, or more indices to
search and therefor had a func called `Index(index string)` and a func
called `Indices(indices ...string)`.
Elastic 3.0 now only uses the singular form that, when applicable, accepts a
variadic type. E.g. in the case of the `SearchService`, you now only have
one func with the following signature: `Index(indices ...string)`.
Notice this is only limited to `Index(...)` and `Type(...)`. There are other
services with variadic functions. These have not been changed.
## Multiple calls to variadic functions
Some services with variadic functions have cleared the underlying slice when
called while other services just add to the existing slice. This has now been
normalized to always add to the underlying slice.
Example for Elastic 2.0 (old):
```go
// Would only cleared scroll id "two"
// because ScrollId cleared the values when called multiple times
client.ClearScroll().ScrollId("one").ScrollId("two").Do()
```
Example for Elastic 3.0 (new):
```go
// Now (correctly) clears both scroll id "one" and "two"
// because ScrollId no longer clears the values when called multiple times
client.ClearScroll().ScrollId("one").ScrollId("two").Do()
```
## Ping service requires URL
The `Ping` service raised some issues because it is different from all
other services. If not explicitly given a URL, it always pings `127.0.0.1:9200`.
Users expected to ping the cluster, but that is not possible as the cluster
can be a set of many nodes: So which node do we ping then?
To make it more clear, the `Ping` function on the client now requires users
to explicitly set the URL of the node to ping.
## Meta fields
Many of the meta fields e.g. `_parent` or `_routing` are now
[part of the top-level of a document](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_mapping_changes.html#migration-meta-fields)
and are no longer returned as parts of the `fields` object. We had to change
larger parts of e.g. the `Reindexer` to get it to work seamlessly with Elasticsearch 2.0.
Notice that all stored meta-fields are now [returned by default](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_crud_and_routing_changes.html#_all_stored_meta_fields_returned_by_default).
## HasParentQuery / HasChildQuery
`NewHasParentQuery` and `NewHasChildQuery` must now include both parent/child type and query. It is now in line with the Java API.
Example for Elastic 2.0 (old):
```go
allQ := elastic.NewMatchAllQuery()
q := elastic.NewHasChildFilter("tweet").Query(&allQ)
```
Example for Elastic 3.0 (new):
```go
q := elastic.NewHasChildQuery("tweet", elastic.NewMatchAllQuery())
```
## SetBasicAuth client option
You can now tell Elastic to pass HTTP Basic Auth credentials with each request. In previous versions of Elastic you had to set up your own `http.Transport` to do this. This should make it more convenient to use Elastic in combination with [Shield](https://www.elastic.co/products/shield) in its [basic setup](https://www.elastic.co/guide/en/shield/current/enable-basic-auth.html).
Example:
```go
client, err := elastic.NewClient(elastic.SetBasicAuth("user", "secret"))
if err != nil {
log.Fatal(err)
}
```
## Delete-by-Query API
The Delete-by-Query API is [a plugin now](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_removed_features.html#_delete_by_query_is_now_a_plugin). It is no longer core part of Elasticsearch. You can [install it as a plugin as described here](https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/plugins-delete-by-query.html).
Elastic 3.0 still contains the `DeleteByQueryService`, but you need to install the plugin first. If you don't install it and use `DeleteByQueryService` you will most probably get a 404.
An older version of this document stated the following:
> Elastic 3.0 still contains the `DeleteByQueryService` but it will fail with `ErrPluginNotFound` when the plugin is not installed.
>
> Example for Elastic 3.0 (new):
>
> ```go
> _, err := client.DeleteByQuery().Query(elastic.NewTermQuery("client", "1")).Do()
> if err == elastic.ErrPluginNotFound {
> // Delete By Query API is not available
> }
> ```
I have decided that this is not a good way to handle the case of a missing plugin. The main reason is that with this logic, you'd always have to check if the plugin is missing in case of an error. This is not only slow, but it also puts logic into a service where it should really be just opaque and return the response of Elasticsearch.
If you rely on certain plugins to be installed, you should check on startup. That's where the following two helpers come into play.
## HasPlugin and SetRequiredPlugins
Some of the core functionality of Elasticsearch has now been moved into plugins. E.g. the Delete-by-Query API is [a plugin now](https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/plugins-delete-by-query.html).
You need to make sure to add these plugins to your Elasticsearch installation to still be able to use the `DeleteByQueryService`. You can test this now with the `HasPlugin(name string)` helper in the client.
Example for Elastic 3.0 (new):
```go
err, found := client.HasPlugin("delete-by-query")
if err == nil && found {
// ... Delete By Query API is available
}
```
To simplify this process, there is now a `SetRequiredPlugins` helper that can be passed as an option func when creating a new client. If the plugin is not installed, the client wouldn't be created in the first place.
```go
// Will raise an error if the "delete-by-query" plugin is NOT installed
client, err := elastic.NewClient(elastic.SetRequiredPlugins("delete-by-query"))
if err != nil {
log.Fatal(err)
}
```
Notice that there also is a way to define [mandatory plugins](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-plugins.html#_mandatory_plugins) in the Elasticsearch configuration file.
## Common Query has been renamed to Common Terms Query
The `CommonQuery` has been renamed to `CommonTermsQuery` to be in line with the [Java API](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_java_api_changes.html#_query_filter_refactoring).
## Remove `MoreLikeThis` and `MoreLikeThisField`
The More Like This API and the More Like This Field query [have been removed](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_more_like_this) and replaced with the `MoreLikeThisQuery`.
## Remove Filtered Query
With the merge of queries and filters, the [filtered query became deprecated](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_literal_filtered_literal_query_and_literal_query_literal_filter_deprecated). While it is only deprecated and therefore still available in Elasticsearch 2.0, we have decided to remove it from Elastic 3.0. Why? Because we think that when you're already forced to rewrite many of your application code, it might be a good chance to get rid of things that are deprecated as well. So you might simply change your filtered query with a boolean query as [described here](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_literal_filtered_literal_query_and_literal_query_literal_filter_deprecated).
## Remove FuzzyLikeThis and FuzzyLikeThisField
Both have been removed from Elasticsearch 2.0 as well.
## Remove LimitFilter
The `limit` filter is [deprecated in Elasticsearch 2.0](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_literal_limit_literal_filter_deprecated) and becomes a no-op. Now is a good chance to remove it from your application as well. Use the `terminate_after` parameter in your search [as described here](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/search-request-body.html) to achieve similar effects.
## Remove `_cache` and `_cache_key` from filters
Both have been [removed from Elasticsearch 2.0 as well](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_filter_auto_caching).
## Partial fields are gone
Partial fields are [removed in Elasticsearch 2.0](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_search_changes.html#_partial_fields) in favor of [source filtering](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/search-request-source-filtering.html).
## Scripting
A [`Script`](https://github.com/olivere/elastic/blob/release-branch.v3/script.go) type has been added to Elastic 3.0. In Elastic 2.0, there were various places (e.g. aggregations) where you could just add the script as a string, specify the scripting language, add parameters etc. With Elastic 3.0, you should now always use the `Script` type.
Example for Elastic 2.0 (old):
```go
update, err := client.Update().Index("twitter").Type("tweet").Id("1").
Script("ctx._source.retweets += num").
ScriptParams(map[string]interface{}{"num": 1}).
Upsert(map[string]interface{}{"retweets": 0}).
Do()
```
Example for Elastic 3.0 (new):
```go
update, err := client.Update().Index("twitter").Type("tweet").Id("1").
Script(elastic.NewScript("ctx._source.retweets += num").Param("num", 1)).
Upsert(map[string]interface{}{"retweets": 0}).
Do()
```
## Cluster State
The combination of `Metric(string)` and `Metrics(...string)` has been replaced by a single func with the signature `Metric(...string)`.
## Unexported structs in response
Services generally return a typed response from a `Do` func. Those structs are exported so that they can be passed around in your own application. In Elastic 3.0 however, we changed that (most) sub-structs are now unexported, meaning: You can only pass around the whole response, not sub-structures of it. This makes it easier for restructuring responses according to the Elasticsearch API. See [`ClusterStateResponse`](https://github.com/olivere/elastic/blob/release-branch.v3/cluster_state.go#L182) as an example.
## Add offset to Histogram aggregation
Histogram aggregations now have an [offset](https://github.com/elastic/elasticsearch/pull/9505) option.
## Services
### REST API specification
As you might know, Elasticsearch comes with a REST API specification. The specification describes the endpoints in a JSON structure.
Most services in Elastic predated the REST API specification. We are in the process of bringing all these services in line with the specification. Services can be generated by `go generate` (not 100% automatic though). This is an ongoing process.
This probably doesn't mean a lot to you. However, you can now be more confident that Elastic supports all features that the REST API specification describes.
At the same time, the file names of the services are renamed to match the REST API specification naming.
### REST API Test Suite
The REST API specification of Elasticsearch comes along with a test suite that official clients typically use to test for conformance. Up until now, Elastic didn't run this test suite. However, we are in the process of setting up infrastructure and tests to match this suite as well.
This process in not completed though.

# Changes in Elastic 5.0
## Enforce context.Context in PerformRequest and Do
We enforce the usage of `context.Context` everywhere you execute a request.
You need to change all your `Do()` calls to pass a context: `Do(ctx)`.
This enables automatic request cancelation and many other patterns.
If you don't need this, simply pass `context.TODO()` or `context.Background()`.
## Warmers removed
Warmers are no longer necessary and have been [removed in ES 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_index_apis.html#_warmers).
## Optimize removed
Optimize was deprecated in ES 2.0 and has been [removed in ES 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_rest_api_changes.html#_literal__optimize_literal_endpoint_removed).
Use [Force Merge](https://www.elastic.co/guide/en/elasticsearch/reference/master/indices-forcemerge.html) instead.
## Missing Query removed
The `missing` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/query-dsl-exists-query.html#_literal_missing_literal_query).
Use `exists` query with `must_not` in `bool` query instead.
## And Query removed
The `and` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
Use `must` clauses in a `bool` query instead.
## Not Query removed
TODO Is it removed?
## Or Query removed
The `or` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
Use `should` clauses in a `bool` query instead.
## Filtered Query removed
The `filtered` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
Use `bool` query instead, which supports `filter` clauses too.
## Limit Query removed
The `limit` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
Use the `terminate_after` parameter instead.
# Template Query removed
The `template` query has been [deprecated](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/query-dsl-template-query.html). You should use
Search Templates instead.
We remove it from Elastic 5.0 as the 5.0 update is already a good opportunity
to get rid of old stuff.
## `_timestamp` and `_ttl` removed
Both of these fields were deprecated and are now [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_mapping_changes.html#_literal__timestamp_literal_and_literal__ttl_literal).
## Search template Put/Delete API returns `acknowledged` only
The response type for Put/Delete search templates has changed.
It only returns a single `acknowledged` flag now.
## Fields has been renamed to Stored Fields
The `fields` parameter has been renamed to `stored_fields`.
See [here](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/breaking_50_search_changes.html#_literal_fields_literal_parameter).
## Fielddatafields has been renamed to Docvaluefields
The `fielddata_fields` parameter [has been renamed](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/breaking_50_search_changes.html#_literal_fielddata_fields_literal_parameter)
to `docvalue_fields`.
## Type exists endpoint changed
The endpoint for checking whether a type exists has been changed from
`HEAD {index}/{type}` to `HEAD {index}/_mapping/{type}`.
See [here](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking_50_rest_api_changes.html#_literal_head_index_type_literal_replaced_with_literal_head_index__mapping_type_literal).
## Refresh parameter changed
The `?refresh` parameter previously could be a boolean value. It indicated
whether changes made by a request (e.g. by the Bulk API) should be immediately
visible in search, or not. Using `refresh=true` had the positive effect of
immediately seeing the changes when searching; the negative effect is that
it is a rather big performance hit.
With 5.0, you now have the choice between these 3 values.
* `"true"` - Refresh immediately
* `"false"` - Do not refresh (the default value)
* `"wait_for"` - Wait until ES made the document visible in search
See [?refresh](https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-refresh.html) in the documentation.
Notice that `true` and `false` (the boolean values) are no longer available
now in Elastic. You must use a string instead, with one of the above values.
## ReindexerService removed
The `ReindexerService` was a custom solution that was started in the ES 1.x era
to automate reindexing data, from one index to another or even between clusters.
ES 2.3 introduced its own [Reindex API](https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-reindex.html)
so we're going to remove our custom solution and ask you to use the native reindexer.
The `ReindexService` is available via `client.Reindex()` (which used to point
to the custom reindexer).
## Delete By Query back in core
The [Delete By Query API](https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-delete-by-query.html)
was moved into a plugin in 2.0. Now its back in core with a complete rewrite based on the Bulk API.
It has it's own endpoint at `/_delete_by_query`.
Delete By Query, Reindex, and Update By Query are very similar under the hood.
## Reindex, Delete By Query, and Update By Query response changed
The response from the above APIs changed a bit. E.g. the `retries` value
used to be an `int64` and returns separate values for `bulk` and `search` now:
```
// Old
{
...
"retries": 123,
...
}
```
```
// New
{
...
"retries": {
"bulk": 123,
"search": 0
},
...
}
```
## ScanService removed
The `ScanService` is removed. Use the (new) `ScrollService` instead.
## New ScrollService
There was confusion around `ScanService` and `ScrollService` doing basically
the same. One was returning slices and didn't support all query details, the
other returned one document after another and wasn't safe for concurrent use.
So we merged the two and merged it into a new `ScrollService` that
removes all the problems with the older services.
In other words:
If you used `ScanService`, switch to `ScrollService`.
If you used the old `ScrollService`, you might need to fix some things but
overall it should just work.
Changes:
- We replaced `elastic.EOS` with `io.EOF` to indicate the "end of scroll".
TODO Not implemented yet
## Suggesters
They have been [completely rewritten in ES 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_suggester.html).
Some changes:
- Suggesters no longer have an [output](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_suggester.html#_simpler_completion_indexing).
TODO Fix all structural changes in suggesters
## Percolator
Percolator has [changed considerably](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/breaking_50_percolator.html).
Elastic 5.0 adds the new
[Percolator Query](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/query-dsl-percolate-query.html)
which can be used in combination with the new
[Percolator type](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/percolator.html).
The Percolate service is removed from Elastic 5.0.
## Remove Consistency, add WaitForActiveShards
The `consistency` parameter has been removed in a lot of places, e.g. the Bulk,
Index, Delete, Delete-by-Query, Reindex, Update, and Update-by-Query API.
It has been replaced by a somewhat similar `wait_for_active_shards` parameter.
See https://github.com/elastic/elasticsearch/pull/19454.

# How to contribute
Elastic is an open-source project and we are looking forward to each
contribution.
Notice that while the [official Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html) is rather good, it is a high-level
overview of the features of Elasticsearch. However, Elastic tries to resemble
the Java API of Elasticsearch which you can find [on GitHub](https://github.com/elastic/elasticsearch).
This explains why you might think that some options are strange or missing
in Elastic, while often they're just different. Please check the Java API first.
Having said that: Elasticsearch is moving fast and it might be very likely
that we missed some features or changes. Feel free to change that.
## Your Pull Request
To make it easy to review and understand your changes, please keep the
following things in mind before submitting your pull request:
* You compared the existing implemenation with the Java API, did you?
* Please work on the latest possible state of `olivere/elastic`.
Use `release-branch.v2` for targeting Elasticsearch 1.x and
`release-branch.v3` for targeting 2.x.
* Create a branch dedicated to your change.
* If possible, write a test case which confirms your change.
* Make sure your changes and your tests work with all recent versions of
Elasticsearch. We currently support Elasticsearch 1.7.x in the
release-branch.v2 and Elasticsearch 2.x in the release-branch.v3.
* Test your changes before creating a pull request (`go test ./...`).
* Don't mix several features or bug fixes in one pull request.
* Create a meaningful commit message.
* Explain your change, e.g. provide a link to the issue you are fixing and
probably a link to the Elasticsearch documentation and/or source code.
* Format your source with `go fmt`.
## Additional Resources
* [GitHub documentation](http://help.github.com/)

# Elastic
Elastic is an [Elasticsearch](http://www.elasticsearch.org/) client for the
[Go](http://www.golang.org/) programming language.
[![Build Status](https://travis-ci.org/olivere/elastic.svg?branch=release-branch.v5)](https://travis-ci.org/olivere/elastic)
[![Godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](http://godoc.org/gopkg.in/olivere/elastic.v5)
[![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/olivere/elastic/master/LICENSE)
See the [wiki](https://github.com/olivere/elastic/wiki) for additional information about Elastic.
## Releases
**The release branches (e.g. [`release-branch.v5`](https://github.com/olivere/elastic/tree/release-branch.v5))
are actively being worked on and can break at any time.
If you want to use stable versions of Elastic, please use the packages released via [gopkg.in](https://gopkg.in).**
Here's the version matrix:
Elasticsearch version | Elastic version -| Package URL
----------------------|------------------|------------
5.x | 5.0 | [`gopkg.in/olivere/elastic.v5`](https://gopkg.in/olivere/elastic.v5) ([source](https://github.com/olivere/elastic/tree/release-branch.v5) [doc](http://godoc.org/gopkg.in/olivere/elastic.v5))
2.x | 3.0 | [`gopkg.in/olivere/elastic.v3`](https://gopkg.in/olivere/elastic.v3) ([source](https://github.com/olivere/elastic/tree/release-branch.v3) [doc](http://godoc.org/gopkg.in/olivere/elastic.v3))
1.x | 2.0 | [`gopkg.in/olivere/elastic.v2`](https://gopkg.in/olivere/elastic.v2) ([source](https://github.com/olivere/elastic/tree/release-branch.v2) [doc](http://godoc.org/gopkg.in/olivere/elastic.v2))
0.9-1.3 | 1.0 | [`gopkg.in/olivere/elastic.v1`](https://gopkg.in/olivere/elastic.v1) ([source](https://github.com/olivere/elastic/tree/release-branch.v1) [doc](http://godoc.org/gopkg.in/olivere/elastic.v1))
**Example:**
You have installed Elasticsearch 5.0.0 and want to use Elastic.
As listed above, you should use Elastic 5.0.
So you first install the stable release of Elastic 5.0 from gopkg.in.
```sh
$ go get gopkg.in/olivere/elastic.v5
```
You then import it with this import path:
```go
import elastic "gopkg.in/olivere/elastic.v5"
```
### Elastic 5.0
Elastic 5.0 targets Elasticsearch 5.0.0 and later. Elasticsearch 5.0.0 was
[released on 26th October 2016](https://www.elastic.co/blog/elasticsearch-5-0-0-released).
Notice that there are will be a lot of [breaking changes in Elasticsearch 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking-changes-5.0.html)
and we used this as an opportunity to [clean up and refactor Elastic](https://github.com/olivere/elastic/blob/release-branch.v5/CHANGELOG-5.0.md)
as we did in the transition from Elastic 2.0 (for Elasticsearch 1.x) to Elastic 3.0 (for Elasticsearch 2.x).
Furthermore, the jump in version numbers will give us a chance to be in sync with the Elastic Stack.
### Elastic 3.0
Elastic 3.0 targets Elasticsearch 2.x and is published via [`gopkg.in/olivere/elastic.v3`](https://gopkg.in/olivere/elastic.v3).
Elastic 3.0 will only get critical bug fixes. You should update to a recent version.
### Elastic 2.0
Elastic 2.0 targets Elasticsearch 1.x and is published via [`gopkg.in/olivere/elastic.v2`](https://gopkg.in/olivere/elastic.v2).
Elastic 2.0 will only get critical bug fixes. You should update to a recent version.
### Elastic 1.0
Elastic 1.0 is deprecated. You should really update Elasticsearch and Elastic
to a recent version.
However, if you cannot update for some reason, don't worry. Version 1.0 is
still available. All you need to do is go-get it and change your import path
as described above.
## Status
We use Elastic in production since 2012. Elastic is stable but the API changes
now and then. We strive for API compatibility.
However, Elasticsearch sometimes introduces [breaking changes](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking-changes.html)
and we sometimes have to adapt.
Having said that, there have been no big API changes that required you
to rewrite your application big time. More often than not it's renaming APIs
and adding/removing features so that Elastic is in sync with Elasticsearch.
Elastic has been used in production with the following Elasticsearch versions:
0.90, 1.0-1.7, and 2.0-2.4.1. Furthermore, we use [Travis CI](https://travis-ci.org/)
to test Elastic with the most recent versions of Elasticsearch and Go.
See the [.travis.yml](https://github.com/olivere/elastic/blob/master/.travis.yml)
file for the exact matrix and [Travis](https://travis-ci.org/olivere/elastic)
for the results.
Elasticsearch has quite a few features. Most of them are implemented
by Elastic. I add features and APIs as required. It's straightforward
to implement missing pieces. I'm accepting pull requests :-)
Having said that, I hope you find the project useful.
## Getting Started
The first thing you do is to create a [Client](https://github.com/olivere/elastic/blob/master/client.go).
The client connects to Elasticsearch on `http://127.0.0.1:9200` by default.
You typically create one client for your app. Here's a complete example of
creating a client, creating an index, adding a document, executing a search etc.
An example is available [here](https://olivere.github.io/elastic/)
Here's a [link to a complete working example for v3](https://gist.github.com/olivere/114347ff9d9cfdca7bdc0ecea8b82263).
See the [wiki](https://github.com/olivere/elastic/wiki) for more details.
