This removes our vendored dependencies. They provide no value for our
own build or development processes. For our source releases, the build
job can accomplish the same thing by a "go mod vendor" to recreate the
vendor dir (from the cryptographically verified dependencies).

# cli.go
cli.go is simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
You can view the API docs here:
http://godoc.org/github.com/codegangsta/cli
## Overview
Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app.
This is where cli.go comes into play. cli.go makes command line programming fun, organized, and expressive!
## Installation
Make sure you have a working Go environment (go 1.1 is *required*). [See the install instructions](http://golang.org/doc/install.html).
To install cli.go, simply run:
```
$ go get github.com/codegangsta/cli
```
Make sure your PATH includes to the `$GOPATH/bin` directory so your commands can be easily used:
```
export PATH=$PATH:$GOPATH/bin
```
## Getting Started
One of the philosophies behind cli.go is that an API should be playful and full of discovery. So a cli.go app can be as little as one line of code in `main()`.
``` go
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
cli.NewApp().Run(os.Args)
}
```
This app will run and show help text, but is not very useful. Let's give an action to execute and some help documentation:
``` go
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Name = "boom"
app.Usage = "make an explosive entrance"
app.Action = func(c *cli.Context) {
println("boom! I say!")
}
app.Run(os.Args)
}
```
Running this already gives you a ton of functionality, plus support for things like subcommands and flags, which are covered below.
## Example
Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness!
``` go
/* greet.go */
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Name = "greet"
app.Usage = "fight the loneliness!"
app.Action = func(c *cli.Context) {
println("Hello friend!")
}
app.Run(os.Args)
}
```
Install our command to the `$GOPATH/bin` directory:
```
$ go install
```
Finally run our new command:
```
$ greet
Hello friend!
```
cli.go also generates some bitchass help text:
```
$ greet help
NAME:
greet - fight the loneliness!
USAGE:
greet [global options] command [command options] [arguments...]
VERSION:
0.0.0
COMMANDS:
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS
--version Shows version information
```
### Arguments
You can lookup arguments by calling the `Args` function on cli.Context.
``` go
...
app.Action = func(c *cli.Context) {
println("Hello", c.Args()[0])
}
...
```
### Flags
Setting and querying flags is simple.
``` go
...
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang",
Value: "english",
Usage: "language for the greeting",
},
}
app.Action = func(c *cli.Context) {
name := "someone"
if len(c.Args()) > 0 {
name = c.Args()[0]
}
if c.String("lang") == "spanish" {
println("Hola", name)
} else {
println("Hello", name)
}
}
...
```
#### Alternate Names
You can set alternate (or short) names for flags by providing a comma-delimited list for the Name. e.g.
``` go
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang, l",
Value: "english",
Usage: "language for the greeting",
},
}
```
#### Values from the Environment
You can also have the default value set from the environment via EnvVar. e.g.
``` go
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang, l",
Value: "english",
Usage: "language for the greeting",
EnvVar: "APP_LANG",
},
}
```
That flag can then be set with `--lang spanish` or `-l spanish`. Note that giving two different forms of the same flag in the same command invocation is an error.
### Subcommands
Subcommands can be defined for a more git-like command line app.
```go
...
app.Commands = []cli.Command{
{
Name: "add",
ShortName: "a",
Usage: "add a task to the list",
Action: func(c *cli.Context) {
println("added task: ", c.Args().First())
},
},
{
Name: "complete",
ShortName: "c",
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task: ", c.Args().First())
},
},
{
Name: "template",
ShortName: "r",
Usage: "options for task templates",
Subcommands: []cli.Command{
{
Name: "add",
Usage: "add a new template",
Action: func(c *cli.Context) {
println("new task template: ", c.Args().First())
},
},
{
Name: "remove",
Usage: "remove an existing template",
Action: func(c *cli.Context) {
println("removed task template: ", c.Args().First())
},
},
},
},
}
...
```
### Bash Completion
You can enable completion commands by setting the EnableBashCompletion
flag on the App object. By default, this setting will only auto-complete to
show an app's subcommands, but you can write your own completion methods for
the App or its subcommands.
```go
...
var tasks = []string{"cook", "clean", "laundry", "eat", "sleep", "code"}
app := cli.NewApp()
app.EnableBashCompletion = true
app.Commands = []cli.Command{
{
Name: "complete",
ShortName: "c",
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task: ", c.Args().First())
},
BashComplete: func(c *cli.Context) {
// This will complete if no args are passed
if len(c.Args()) > 0 {
return
}
for _, t := range tasks {
println(t)
}
},
}
}
...
```
#### To Enable
Source the autocomplete/bash_autocomplete file in your .bashrc file while
setting the PROG variable to the name of your program:
`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete`
## About
cli.go is written by none other than the [Code Gangsta](http://codegangsta.io)

go-nat-pmp
==========
A Go language client for the NAT-PMP internet protocol for port mapping and discovering the external
IP address of a firewall.
NAT-PMP is supported by Apple brand routers and open source routers like Tomato and DD-WRT.
See http://tools.ietf.org/html/draft-cheshire-nat-pmp-03
Get the package
---------------
go get -u github.com/jackpal/go-nat-pmp
Usage
-----
import natpmp "github.com/jackpal/go-nat-pmp"
client := natpmp.NewClient(gatewayIP)
response, err := client.GetExternalAddress()
if err != nil {
return
}
print("External IP address:", response.ExternalIPAddress)
Notes
-----
There doesn't seem to be an easy way to programmatically determine the address of the default gateway.
(Linux and OSX have a "routes" kernel API that can be examined to get this information, but there is
no Go package for getting this information.)
Clients
-------
This library is used in the Taipei Torrent BitTorrent client http://github.com/jackpal/Taipei-Torrent

go-lz4
======
go-lz4 is port of LZ4 lossless compression algorithm to Go. The original C code
is located at:
https://github.com/Cyan4973/lz4
Status
------
[![Build Status](https://secure.travis-ci.org/bkaradzic/go-lz4.png)](http://travis-ci.org/bkaradzic/go-lz4)
[![GoDoc](https://godoc.org/github.com/bkaradzic/go-lz4?status.png)](https://godoc.org/github.com/bkaradzic/go-lz4)
Usage
-----
go get github.com/bkaradzic/go-lz4
import "github.com/bkaradzic/go-lz4"
The package name is `lz4`
Notes
-----
* go-lz4 saves a uint32 with the original uncompressed length at the beginning
of the encoded buffer. They may get in the way of interoperability with
other implementations.

Rolling Hashes
==============
Philosophy
----------
This package contains several various rolling hashes for you to play with
crazy ideas. The API design philosophy is to stick as closely as possible
to the interface provided by the builtin hash package (the hashes
implemented here are effectively drop-in replacements for their builtin
counterparts), while providing simultaneously the highest speed and
simplicity.
Usage
-----
A [`rollinghash.Hash`](https://godoc.org/github.com/chmduquesne/rollinghash#Hash)
is just a [`hash.Hash`](https://golang.org/pkg/hash/#Hash) which
implements the
[`Roller`](https://godoc.org/github.com/chmduquesne/rollinghash#Roller)
interface. Here is how it is typically used:
```golang
data := []byte("here is some data to roll on")
h := buzhash64.New()
n := 16
// Initialize the rolling window
h.Write(data[:n])
for _, c := range(data[n:]) {
// Slide the window and update the hash
h.Roll(c)
// Get the updated hash value
fmt.Println(h.Sum64())
}
```
Gotchas
-------
The rolling window MUST be initialized by calling `Write` first (which
saves a copy). The byte leaving the rolling window is inferred from the
internal copy of the rolling window, which is updated with every call to
`Roll`.
If you want your code to run at the highest speed, do NOT cast the result
of a `New()` as a rollinghash.Hash. Instead, use the native type returned
by `New()`. This is because the go compiler cannot inline calls from an
interface. When later you call Roll(), the native type call will be
inlined by the compiler, but not the casted type call.
```golang
var h1 rollinghash.Hash
h1 = buzhash32.New()
h2 := buzhash32.New()
[...]
h1.Roll(b) // Not inlined (slow)
h2.Roll(b) // inlined (fast)
```
What's new in v4
----------------
In v4:
* `Write` has become fully consistent with `hash.Hash`. As opposed to
previous versions, where writing data would reinitialize the window, it
now appends this data to the existing window. In order to reset the
window, one should instead use the `Reset` method.
* Calling `Roll` on an empty window is considered a bug, and now triggers
a panic.
Brief reminder of the behaviors in previous versions:
* From v0.x.x to v2.x.x: `Roll` returns an error for an empty window.
`Write` reinitializes the rolling window.
* v3.x.x : `Roll` does not return anything. `Write` still reinitializes
the rolling window. The rolling window always has a minimum size of 1,
which yields wrong results when using roll before having initialized the
window.
Go versions
-----------
The `RabinKarp64` rollinghash does not yield consistent results before
go1.7. This is because it uses `Rand.Read()` from the builtin `math/rand`.
This function was [fixed in go
1.7](https://golang.org/doc/go1.7#math_rand) to produce a consistent
stream of bytes that is independant of the size of the input buffer. If
you depend on this hash, it is strongly recommended to stick to versions
of go superior to 1.7.
License
-------
This code is delivered to you under the terms of the MIT public license,
except the `rabinkarp64` subpackage, which has been adapted from
[restic](https://github.com/restic/chunker) (BSD 2-clause "Simplified").

# messagediff [![Build Status](https://travis-ci.org/d4l3k/messagediff.svg?branch=master)](https://travis-ci.org/d4l3k/messagediff) [![Coverage Status](https://coveralls.io/repos/github/d4l3k/messagediff/badge.svg?branch=master)](https://coveralls.io/github/d4l3k/messagediff?branch=master) [![GoDoc](https://godoc.org/github.com/d4l3k/messagediff?status.svg)](https://godoc.org/github.com/d4l3k/messagediff)
A library for doing diffs of arbitrary Golang structs.
If the unsafe package is available messagediff will diff unexported fields in
addition to exported fields. This is primarily used for testing purposes as it
allows for providing informative error messages.
Optionally, fields in structs can be tagged as `testdiff:"ignore"` to make
messagediff skip it when doing the comparison.
## Example Usage
In a normal file:
```go
package main
import "gopkg.in/d4l3k/messagediff.v1"
type someStruct struct {
A, b int
C []int
}
func main() {
a := someStruct{1, 2, []int{1}}
b := someStruct{1, 3, []int{1, 2}}
diff, equal := messagediff.PrettyDiff(a, b)
/*
diff =
`added: .C[1] = 2
modified: .b = 3`
equal = false
*/
}
```
In a test:
```go
import "gopkg.in/d4l3k/messagediff.v1"
...
type someStruct struct {
A, b int
C []int
}
func TestSomething(t *testing.T) {
want := someStruct{1, 2, []int{1}}
got := someStruct{1, 3, []int{1, 2}}
if diff, equal := messagediff.PrettyDiff(want, got); !equal {
t.Errorf("Something() = %#v\n%s", got, diff)
}
}
```
To ignore a field in a struct, just annotate it with testdiff:"ignore" like
this:
```go
package main
import "gopkg.in/d4l3k/messagediff.v1"
type someStruct struct {
A int
B int `testdiff:"ignore"`
}
func main() {
a := someStruct{1, 2}
b := someStruct{1, 3}
diff, equal := messagediff.PrettyDiff(a, b)
/*
equal = true
diff = ""
*/
}
```
See the `DeepDiff` function for using the diff results programmatically.

# glob.[go](https://golang.org)
[![GoDoc][godoc-image]][godoc-url] [![Build Status][travis-image]][travis-url]
> Go Globbing Library.
## Install
```shell
go get github.com/gobwas/glob
```
## Example
```go
package main
import "github.com/gobwas/glob"
func main() {
var g glob.Glob
// create simple glob
g = glob.MustCompile("*.github.com")
g.Match("api.github.com") // true
// quote meta characters and then create simple glob
g = glob.MustCompile(glob.QuoteMeta("*.github.com"))
g.Match("*.github.com") // true
// create new glob with set of delimiters as ["."]
g = glob.MustCompile("api.*.com", '.')
g.Match("api.github.com") // true
g.Match("api.gi.hub.com") // false
// create new glob with set of delimiters as ["."]
// but now with super wildcard
g = glob.MustCompile("api.**.com", '.')
g.Match("api.github.com") // true
g.Match("api.gi.hub.com") // true
// create glob with single symbol wildcard
g = glob.MustCompile("?at")
g.Match("cat") // true
g.Match("fat") // true
g.Match("at") // false
// create glob with single symbol wildcard and delimiters ['f']
g = glob.MustCompile("?at", 'f')
g.Match("cat") // true
g.Match("fat") // false
g.Match("at") // false
// create glob with character-list matchers
g = glob.MustCompile("[abc]at")
g.Match("cat") // true
g.Match("bat") // true
g.Match("fat") // false
g.Match("at") // false
// create glob with character-list matchers
g = glob.MustCompile("[!abc]at")
g.Match("cat") // false
g.Match("bat") // false
g.Match("fat") // true
g.Match("at") // false
// create glob with character-range matchers
g = glob.MustCompile("[a-c]at")
g.Match("cat") // true
g.Match("bat") // true
g.Match("fat") // false
g.Match("at") // false
// create glob with character-range matchers
g = glob.MustCompile("[!a-c]at")
g.Match("cat") // false
g.Match("bat") // false
g.Match("fat") // true
g.Match("at") // false
// create glob with pattern-alternatives list
g = glob.MustCompile("{cat,bat,[fr]at}")
g.Match("cat") // true
g.Match("bat") // true
g.Match("fat") // true
g.Match("rat") // true
g.Match("at") // false
g.Match("zat") // false
}
```
## Performance
This library is created for compile-once patterns. This means, that compilation could take time, but
strings matching is done faster, than in case when always parsing template.
If you will not use compiled `glob.Glob` object, and do `g := glob.MustCompile(pattern); g.Match(...)` every time, then your code will be much more slower.
Run `go test -bench=.` from source root to see the benchmarks:
Pattern | Fixture | Match | Speed (ns/op)
--------|---------|-------|--------------
`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my cat has very bright eyes` | `true` | 432
`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my dog has very bright eyes` | `false` | 199
`https://*.google.*` | `https://account.google.com` | `true` | 96
`https://*.google.*` | `https://google.com` | `false` | 66

`{https://*.google.*,*yandex.*,*yahoo.*,*mail.ru}` | `http://google.com` | `false` | 197
`{https://*gobwas.com,http://exclude.gobwas.com}` | `https://safe.gobwas.com` | `true` | 22
`{https://*gobwas.com,http://exclude.gobwas.com}` | `http://safe.gobwas.com` | `false` | 24
`abc*` | `abcdef` | `true` | 8.15
`abc*` | `af` | `false` | 5.68
`*def` | `abcdef` | `true` | 8.84
`*def` | `af` | `false` | 5.74
`ab*ef` | `abcdef` | `true` | 15.2
`ab*ef` | `af` | `false` | 10.4
The same things with `regexp` package:
Pattern | Fixture | Match | Speed (ns/op)
--------|---------|-------|--------------
`^[a-z][^a-x].*cat.*[h][^b].*eyes.*$` | `my cat has very bright eyes` | `true` | 2553
`^[a-z][^a-x].*cat.*[h][^b].*eyes.*$` | `my dog has very bright eyes` | `false` | 1383
`^https:\/\/.*\.google\..*$` | `https://account.google.com` | `true` | 1205
`^https:\/\/.*\.google\..*$` | `https://google.com` | `false` | 767

## Syntax
Syntax is inspired by [standard wildcards](http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm),
except that `**` is aka super-asterisk, that do not sensitive for separators.

/*
Package gogoproto provides extensions for protocol buffers to achieve:
- fast marshalling and unmarshalling.
- peace of mind by optionally generating test and benchmark code.
- more canonical Go structures.
- less typing by optionally generating extra helper code.
- goprotobuf compatibility
More Canonical Go Structures
A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
- nullable, if false, a field is generated without a pointer (see warning below).
- embed, if true, the field is generated as an embedded field.
- customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
- customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
- casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums.
- castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
- castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
for a quicker overview.
The following message:
package test;
import "github.com/gogo/protobuf/gogoproto/gogo.proto";
message A {
optional string Description = 1 [(gogoproto.nullable) = false];
optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
}
Will generate a go struct which looks a lot like this:
type A struct {
Description string
Number int64
Id github_com_gogo_protobuf_test_custom.Uuid
}
You will see there are no pointers, since all fields are non-nullable.
You will also see a custom type which marshals to a string.
Be warned it is your responsibility to test your custom types thoroughly.
You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
Next we will embed the message A in message B.
message B {
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
See below that A is embedded in B.
type B struct {
A
G []github_com_gogo_protobuf_test_custom.Uint128
}
Also see the repeated custom type.
type Uint128 [2]uint64
Next we will create a custom name for one of our fields.
message C {
optional int64 size = 1 [(gogoproto.customname) = "MySize"];
}
See below that the field's name is MySize and not Size.
type C struct {
MySize *int64
}
The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
Using customname you can fix this error without changing the field name.
This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
Gogoprotobuf also has some more subtle changes, these could be changed back:
- the generated package name for imports do not have the extra /filename.pb,
but are actually the imports specified in the .proto file.
Gogoprotobuf also has lost some features which should be brought back with time:
- Marshalling and unmarshalling with reflect and without the unsafe package,
this requires work in pointer_reflect.go
Why does nullable break protocol buffer specifications:
The protocol buffer specification states, somewhere, that you should be able to tell whether a
field is set or unset. With the option nullable=false this feature is lost,
since your non-nullable fields will always be set. It can be seen as a layer on top of
protocol buffers, where before and after marshalling all non-nullable fields are set
and they cannot be unset.
Goprotobuf Compatibility:
Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
- gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
- goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
- goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
- goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
- goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
- goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
- goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
- goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
- github.com/gogo/protobuf/plugin/<extension_name>
If you do not use any of these extension the code that is generated
will be the same as if goprotobuf has generated it.
The most complete way to see examples is to look at
github.com/gogo/protobuf/test/thetest.proto
Gogoprototest is a seperate project,
because we want to keep gogoprotobuf independent of goprotobuf,
but we still want to test it thoroughly.
