+
+[]
+(https://travis-ci.org/davecgh/go-spew) [![Coverage Status]
+(https://coveralls.io/repos/davecgh/go-spew/badge.png?branch=master)]
+(https://coveralls.io/r/davecgh/go-spew?branch=master)
+
+Go-spew implements a deep pretty printer for Go data structures to aid in
+debugging. A comprehensive suite of tests with 100% test coverage is provided
+to ensure proper functionality. See `test_coverage.txt` for the gocov coverage
+report. Go-spew is licensed under the liberal ISC license, so it may be used in
+open source or commercial projects.
+
+If you're interested in reading about how this package came to life and some
+of the challenges involved in providing a deep pretty printer, there is a blog
+post about it
+[here](https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
+
+## Documentation
+
+[]
+(http://godoc.org/github.com/davecgh/go-spew/spew)
+
+Full `go doc` style documentation for the project can be viewed online without
+installing this package by using the excellent GoDoc site here:
+http://godoc.org/github.com/davecgh/go-spew/spew
+
+You can also view the documentation locally once the package is installed with
+the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
+http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
+
+## Installation
+
+```bash
+$ go get -u github.com/davecgh/go-spew/spew
+```
+
+## Quick Start
+
+Add this import line to the file you're working in:
+
+```Go
+import "github.com/davecgh/go-spew/spew"
+```
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+
+```Go
+spew.Dump(myVar1, myVar2, ...)
+spew.Fdump(someWriter, myVar1, myVar2, ...)
+str := spew.Sdump(myVar1, myVar2, ...)
+```
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
+compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
+and pointer addresses):
+
+```Go
+spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+```
+
+## Debugging a Web Application Example
+
+Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
+
+```Go
+package main
+
+import (
+ "fmt"
+ "html"
+ "net/http"
+
+ "github.com/davecgh/go-spew/spew"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+ w.Header().Set("Content-Type", "text/html")
+ fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
+ fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
+}
+
+func main() {
+ http.HandleFunc("/", handler)
+ http.ListenAndServe(":8080", nil)
+}
+```
+
+## Sample Dump Output
+
+```
+(main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+ flag: (main.Flag) flagTwo,
+ data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) {
+ (string) "one": (bool) true
+ }
+}
+([]uint8) {
+ 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
+ 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
+ 00000020 31 32 |12|
+}
+```
+
+## Sample Formatter Output
+
+Double pointer to a uint8:
+```
+ %v: <**>5
+ %+v: <**>(0xf8400420d0->0xf8400420c8)5
+ %#v: (**uint8)5
+ %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+```
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+```
+ %v: <*>{1 <*><shown>}
+ %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+ %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+ %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+```
+
+## Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available via the
+spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+```
+* Indent
+ String to use for each indentation level for Dump functions.
+ It is a single space by default. A popular alternative is "\t".
+
+* MaxDepth
+ Maximum number of levels to descend into nested data structures.
+ There is no limit by default.
+
+* DisableMethods
+ Disables invocation of error and Stringer interface methods.
+ Method invocation is enabled by default.
+
+* DisablePointerMethods
+ Disables invocation of error and Stringer interface methods on types
+ which only accept pointer receivers from non-pointer variables. This option
+ relies on access to the unsafe package, so it will not have any effect when
+ running in environments without access to the unsafe package such as Google
+ App Engine or with the "disableunsafe" build tag specified.
+ Pointer method invocation is enabled by default.
+
+* ContinueOnMethod
+ Enables recursion into types after invoking error and Stringer interface
+ methods. Recursion after method invocation is disabled by default.
+
+* SortKeys
+ Specifies map keys should be sorted before being printed. Use
+ this to have a more deterministic, diffable output. Note that
+ only native types (bool, int, uint, floats, uintptr and string)
+ and types which implement error or Stringer interfaces are supported,
+ with other types sorted according to the reflect.Value.String() output
+ which guarantees display stability. Natural map order is used by
+ default.
+
+* SpewKeys
+ SpewKeys specifies that, as a last resort attempt, map keys should be
+ spewed to strings and sorted by those strings. This is only considered
+ if SortKeys is true.
+
+```
+
+## Unsafe Package Dependency
+
+This package relies on the unsafe package to perform some of the more advanced
+features, however it also supports a "limited" mode which allows it to work in
+environments where the unsafe package is not available. By default, it will
+operate in this mode on Google App Engine. The "disableunsafe" build tag may
+also be specified to force the package to build without using the unsafe
+package.

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+ * Pointers are dereferenced and followed
+ * Circular data structures are detected and handled properly
+ * Custom Stringer/error interfaces are optionally invoked, including
+ on unexported types
+ * Custom types which only implement the Stringer/error interfaces via
+ a pointer receiver are optionally invoked when passing non-pointer
+ variables
+ * Byte arrays and slices are dumped like the hexdump -C command which
+ includes offsets, byte values in hex, and ASCII output (only when using
+ Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+ * Dump style which prints with newlines, customizable indentation,
+ and additional debug information such as types and all pointer addresses
+ used to indirect to the final value
+ * A custom Formatter interface that integrates cleanly with the standard fmt
+ package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+ similar to the default %v while providing the additional functionality
+ outlined above and passing unsupported format verbs such as %x and %q
+ along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew. See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+ spew.Dump(myVar1, myVar2, ...)
+ spew.Fdump(someWriter, myVar1, myVar2, ...)
+ str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+ spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+ spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+The following configuration options are available:
+ * Indent
+ String to use for each indentation level for Dump functions.
+ It is a single space by default. A popular alternative is "\t".
+
+ * MaxDepth
+ Maximum number of levels to descend into nested data structures.
+ There is no limit by default.
+
+ * DisableMethods
+ Disables invocation of error and Stringer interface methods.
+ Method invocation is enabled by default.
+
+ * DisablePointerMethods
+ Disables invocation of error and Stringer interface methods on types
+ which only accept pointer receivers from non-pointer variables.
+ Pointer method invocation is enabled by default.
+
+ * ContinueOnMethod
+ Enables recursion into types after invoking error and Stringer interface
+ methods. Recursion after method invocation is disabled by default.
+
+ * SortKeys
+ Specifies map keys should be sorted before being printed. Use
+ this to have a more deterministic, diffable output. Note that
+ only native types (bool, int, uint, floats, uintptr and string)
+ and types which implement error or Stringer interfaces are
+ supported with other types sorted according to the
+ reflect.Value.String() output which guarantees display
+ stability. Natural map order is used by default.
+
+ * SpewKeys
+ Specifies that, as a last resort attempt, map keys should be
+ spewed to strings and sorted by those strings. This is only
+ considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+ spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer. For example, to dump to standard error:
+
+ spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+ str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+ (main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+ flag: (main.Flag) flagTwo,
+ data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) (len=1) {
+ (string) (len=3) "one": (bool) true
+ }
+ }
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+ ([]uint8) (len=32 cap=32) {
+ 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
+ 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
+ 00000020 31 32 |12|
+ }
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations. Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting. In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
+functions have syntax you are most likely already familiar with:
+
+ spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+ spew.Println(myVar, myVar2)
+ spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+ %v: <**>5
+ %+v: <**>(0xf8400420d0->0xf8400420c8)5
+ %#v: (**uint8)5
+ %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+ %v: <*>{1 <*><shown>}
+ %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+ %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+ %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output. Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+ * Circular data structures are detected and handled properly
+ * Custom Stringer/error interfaces are optionally invoked, including
+ on unexported types
+ * Custom types which only implement the Stringer/error interfaces via
+ a pointer receiver are optionally invoked when passing non-pointer
+ variables
+ * Byte arrays and slices are dumped like the hexdump -C command which
+ includes offsets, byte values in hex, and ASCII output
+
+The configuration options are controlled by an exported package global,
+spew.Config. See ConfigState for options documentation.
+
+See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
+get the formatted result as a string.

+standard fmt package for formatting. In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).

+[](https://godoc.org/github.com/pmezard/go-difflib/difflib)
+
+Go-difflib is a partial port of python 3 difflib package. Its main goal
+was to make unified and context diff available in pure Go, mostly for
+testing purposes.
+
+The following class and functions (and related tests) have be ported:
+
+* `SequenceMatcher`
+* `unified_diff()`
+* `context_diff()`
+
+## Installation
+
+```bash
+$ go get github.com/pmezard/go-difflib/difflib
+```
+
+### Quick Start
+
+Diffs are configured with Unified (or ContextDiff) structures, and can
+be output to an io.Writer or returned as a string.
+
+```Go
+diff := UnifiedDiff{
+ A: difflib.SplitLines("foo\nbar\n"),
+ B: difflib.SplitLines("foo\nbaz\n"),
+ FromFile: "Original",
+ ToFile: "Current",
+ Context: 3,
+}
+text, _ := GetUnifiedDiffString(diff)
+fmt.Printf(text)
+```
+
+would output:
+
+```
+--- Original
++++ Current

+// SequenceMatcher compares sequence of strings. The basic
+// algorithm predates, and is a little fancier than, an algorithm
+// published in the late 1980's by Ratcliff and Obershelp under the
+// hyperbolic name "gestalt pattern matching". The basic idea is to find
+// the longest contiguous matching subsequence that contains no "junk"
+// elements (R-O doesn't address junk). The same idea is then applied
+// recursively to the pieces of the sequences to the left and to the right
+// of the matching subsequence. This does not yield minimal edit
+// sequences, but does tend to yield matches that "look right" to people.
+//
+// SequenceMatcher tries to compute a "human-friendly diff" between two
+// sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
+// longest *contiguous* & junk-free matching subsequence. That's what
+// catches peoples' eyes. The Windows(tm) windiff has another interesting
+// notion, pairing up elements that appear uniquely in each sequence.
+// That, and the method here, appear to yield more intuitive difference
+// reports than does diff. This method appears to be the least vulnerable
+// to synching up on blocks of "junk lines", though (like blank lines in
+// ordinary text files, or maybe "<P>" lines in HTML files). That may be
+// because this is the only method of the 3 that has a *concept* of
+// "junk" <wink>.
+//
+// Timing: Basic R-O is cubic time worst case and quadratic time expected
+// case. SequenceMatcher is quadratic time for the worst case and has
+// expected-case behavior dependent in a complicated way on how many
+// elements the sequences have in common; best case time is linear.

+gopsutil: psutil for golang
+==============================
+
+.. image:: https://circleci.com/gh/shirou/gopsutil.svg?&style=shield
+ :target: https://circleci.com/gh/shirou/gopsutil
+
+.. image:: https://coveralls.io/repos/shirou/gopsutil/badge.svg?branch=master
+ :target: https://coveralls.io/r/shirou/gopsutil?branch=master
+
+.. image:: https://godoc.org/github.com/shirou/gopsutil?status.svg
+ :target: http://godoc.org/github.com/shirou/gopsutil
+
+This is a port of psutil (http://pythonhosted.org/psutil/). The challenge is porting all
+psutil functions on some architectures.
+
+
+.. highlights:: Breaking Changes!
+
+ Breaking changes is introduced at v2. See `issue 174 <https://github.com/shirou/gopsutil/issues/174>`_ .
+
+
+Migrating to v2
+-------------------------
+
+On gopsutil itself, `v2migration.sh <https://github.com/shirou/gopsutil/blob/v2/v2migration.sh>`_ is used for migration. It can not be commly used, but it may help to your migration.
+
+
+Available Architectures
+------------------------------------
+
+- FreeBSD i386/amd64
+- Linux i386/amd64/arm(raspberry pi)
+- Windows/amd64
+- Darwin/amd64
+
+All works are implemented without cgo by porting c struct to golang struct.
+
+
+Usage
+---------
+
+Note: gopsutil v2 breaks compatibility. If you want to stay with compatibility, please use v1 branch and vendoring.
+
+.. code:: go
+
+ package main
+
+ import (
+ "fmt"
+
+ "github.com/shirou/gopsutil/mem"
+ )
+
+ func main() {
+ v, _ := mem.VirtualMemory()
+
+ // almost every return value is a struct
+ fmt.Printf("Total: %v, Free:%v, UsedPercent:%f%%\n", v.Total, v.Free, v.UsedPercent)
+
+ // convert to JSON. String() is also implemented
+ fmt.Println(v)
+ }
+
+The output is below.
+
+::
+
+ Total: 3179569152, Free:284233728, UsedPercent:84.508194%
+ {"total":3179569152,"available":492572672,"used":2895335424,"usedPercent":84.50819439828305, (snip...)}
+
+You can set an alternative location to /proc by setting the HOST_PROC environment variable.
+You can set an alternative location to /sys by setting the HOST_SYS environment variable.
+You can set an alternative location to /etc by setting the HOST_ETC environment variable.
+
+Documentation
+------------------------
+
+see http://godoc.org/github.com/shirou/gopsutil
+
+Requrement
+-----------------
+
+- go1.5 or above is required.
+
+
+More Info
+--------------------
+
+Several methods have been added which are not present in psutil, but will provide useful information.
+
+- host/HostInfo() (linux)
+
+ - Hostname
+ - Uptime
+ - Procs
+ - OS (ex: "linux")
+ - Platform (ex: "ubuntu", "arch")
+ - PlatformFamily (ex: "debian")
+ - PlatformVersion (ex: "Ubuntu 13.10")
+ - VirtualizationSystem (ex: "LXC")
+ - VirtualizationRole (ex: "guest"/"host")
+
+- cpu/CPUInfo() (linux, freebsd)
+
+ - CPU (ex: 0, 1, ...)
+ - VendorID (ex: "GenuineIntel")
+ - Family
+ - Model
+ - Stepping
+ - PhysicalID
+ - CoreID
+ - Cores (ex: 2)
+ - ModelName (ex: "Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz")
+ - Mhz
+ - CacheSize
+ - Flags (ex: "fpu vme de pse tsc msr pae mce cx8 ...")
+
+- load/LoadAvg() (linux, freebsd)
+
+ - Load1
+ - Load5
+ - Load15
+
+- docker/GetDockerIDList() (linux only)
+
+ - container id list ([]string)
+
+- docker/CgroupCPU() (linux only)
+
+ - user
+ - system
+
+- docker/CgroupMem() (linux only)
+
+ - various status
+
+- net_protocols (linux only)
+
+ - system wide stats on network protocols (i.e IP, TCP, UDP, etc.)
+ - sourced from /proc/net/snmp
+
+- iptables nf_conntrack (linux only)
+
+ - system wide stats on netfilter conntrack module
+ - sourced from /proc/sys/net/netfilter/nf_conntrack_count
+
+Some codes are ported from Ohai. many thanks.

+// objx - Go package for dealing with maps, slices, JSON and other data.
+//
+// Overview
+//
+// Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes
+// a powerful `Get` method (among others) that allows you to easily and quickly get
+// access to data within the map, without having to worry too much about type assertions,
+// missing data, default values etc.
+//
+// Pattern
+//
+// Objx uses a preditable pattern to make access data from within `map[string]interface{}'s
+// easy.
+//
+// Call one of the `objx.` functions to create your `objx.Map` to get going:
+//
+// m, err := objx.FromJSON(json)
+//
+// NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong,
+// the rest will be optimistic and try to figure things out without panicking.
+//
+// Use `Get` to access the value you're interested in. You can use dot and array
+// notation too:
+//
+// m.Get("places[0].latlng")
+//
+// Once you have saught the `Value` you're interested in, you can use the `Is*` methods
+// to determine its type.
+//
+// if m.Get("code").IsStr() { /* ... */ }
+//
+// Or you can just assume the type, and use one of the strong type methods to
+// extract the real value:
+//
+// m.Get("code").Int()
+//
+// If there's no value there (or if it's the wrong type) then a default value
+// will be returned, or you can be explicit about the default value.
+//
+// Get("code").Int(-1)
+//
+// If you're dealing with a slice of data as a value, Objx provides many useful
+// methods for iterating, manipulating and selecting that data. You can find out more
+// by exploring the index below.
+//
+// Reading data
+//
+// A simple example of how to use Objx:
+//
+// // use MustFromJSON to make an objx.Map from some JSON
+// m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
+//
+// // get the details
+// name := m.Get("name").Str()
+// age := m.Get("age").Int()
+//
+// // get their nickname (or use their name if they
+// // don't have one)
+// nickname := m.Get("nickname").Str(name)
+//
+// Ranging
+//
+// Since `objx.Map` is a `map[string]interface{}` you can treat it as such. For
+// example, to `range` the data, do what you would expect:
+//
+// m := objx.MustFromJSON(json)
+// for key, value := range m {
+//
+// /* ... do your magic ... */
+//
+// }

+Testify - Thou Shalt Write Tests
+================================
+
+[](https://travis-ci.org/stretchr/testify)
+
+Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.
+
+Features include:
+
+ * [Easy assertions](#assert-package)
+ * [Mocking](#mock-package)
+ * [HTTP response trapping](#http-package)
+ * [Testing suite interfaces and functions](#suite-package)
+
+Get started:
+
+ * Install testify with [one line of code](#installation), or [update it with another](#staying-up-to-date)
+ * For an introduction to writing test code in Go, see http://golang.org/doc/code.html#Testing
+ * Check out the API Documentation http://godoc.org/github.com/stretchr/testify
+ * To make your testing life easier, check out our other project, [gorc](http://github.com/stretchr/gorc)
+ * A little about [Test-Driven Development (TDD)](http://en.wikipedia.org/wiki/Test-driven_development)
+
+
+
+[`assert`](http://godoc.org/github.com/stretchr/testify/assert "API documentation") package
+-------------------------------------------------------------------------------------------
+
+The `assert` package provides some helpful methods that allow you to write better test code in Go.
+
+ * Prints friendly, easy to read failure descriptions
+ * Allows for very readable code
+ * Optionally annotate each assertion with a message
+
+See it in action:
+
+```go
+package yours
+
+import (
+ "testing"
+ "github.com/stretchr/testify/assert"
+)
+
+func TestSomething(t *testing.T) {
+
+ // assert equality
+ assert.Equal(t, 123, 123, "they should be equal")
+
+ // assert inequality
+ assert.NotEqual(t, 123, 456, "they should not be equal")
+
+ // assert for nil (good for errors)
+ assert.Nil(t, object)
+
+ // assert for not nil (good when you expect something)
+ if assert.NotNil(t, object) {
+
+ // now we know that object isn't nil, we are safe to make
+ // further assertions without causing any errors
+ assert.Equal(t, "Something", object.Value)
+
+ }
+
+}
+```
+
+ * Every assert func takes the `testing.T` object as the first argument. This is how it writes the errors out through the normal `go test` capabilities.
+ * Every assert func returns a bool indicating whether the assertion was successful or not, this is useful for if you want to go on making further assertions under certain conditions.
+
+if you assert many times, use the below:
+
+```go
+package yours
+
+import (
+ "testing"
+ "github.com/stretchr/testify/assert"
+)
+
+func TestSomething(t *testing.T) {
+ assert := assert.New(t)
+
+ // assert equality
+ assert.Equal(123, 123, "they should be equal")
+
+ // assert inequality
+ assert.NotEqual(123, 456, "they should not be equal")
+
+ // assert for nil (good for errors)
+ assert.Nil(object)
+
+ // assert for not nil (good when you expect something)
+ if assert.NotNil(object) {
+
+ // now we know that object isn't nil, we are safe to make
+ // further assertions without causing any errors
+ assert.Equal("Something", object.Value)
+ }
+}
+```
+
+[`require`](http://godoc.org/github.com/stretchr/testify/require "API documentation") package
+---------------------------------------------------------------------------------------------
+
+The `require` package provides same global functions as the `assert` package, but instead of returning a boolean result they terminate current test.
+
+See [t.FailNow](http://golang.org/pkg/testing/#T.FailNow) for details.
+
+
+[`http`](http://godoc.org/github.com/stretchr/testify/http "API documentation") package
+---------------------------------------------------------------------------------------
+
+The `http` package contains test objects useful for testing code that relies on the `net/http` package. Check out the [(deprecated) API documentation for the `http` package](http://godoc.org/github.com/stretchr/testify/http).
+
+We recommend you use [httptest](http://golang.org/pkg/net/http/httptest) instead.
+
+[`mock`](http://godoc.org/github.com/stretchr/testify/mock "API documentation") package
+----------------------------------------------------------------------------------------
+
+The `mock` package provides a mechanism for easily writing mock objects that can be used in place of real objects when writing test code.
+
+An example test function that tests a piece of code that relies on an external object `testObj`, can setup expectations (testify) and assert that they indeed happened:
+
+```go
+package yours
+
+import (
+ "testing"
+ "github.com/stretchr/testify/mock"
+)
+
+/*
+ Test objects
+*/
+
+// MyMockedObject is a mocked object that implements an interface
+// that describes an object that the code I am testing relies on.
+type MyMockedObject struct{
+ mock.Mock
+}
+
+// DoSomething is a method on MyMockedObject that implements some interface
+// and just records the activity, and returns what the Mock object tells it to.
+//
+// In the real object, this method would do something useful, but since this
+// is a mocked object - we're just going to stub it out.
+//
+// NOTE: This method is not being tested here, code that uses this object is.
+func (m *MyMockedObject) DoSomething(number int) (bool, error) {
+
+ args := m.Called(number)
+ return args.Bool(0), args.Error(1)
+
+}
+
+/*
+ Actual test functions
+*/
+
+// TestSomething is an example of how to use our test object to
+// make assertions about some target code we are testing.
+func TestSomething(t *testing.T) {
+
+ // create an instance of our test object
+ testObj := new(MyMockedObject)
+
+ // setup expectations
+ testObj.On("DoSomething", 123).Return(true, nil)
+
+ // call the code we are testing
+ targetFuncThatDoesSomethingWithObj(testObj)
+
+ // assert that the expectations were met
+ testObj.AssertExpectations(t)
+
+}
+```
+
+For more information on how to write mock code, check out the [API documentation for the `mock` package](http://godoc.org/github.com/stretchr/testify/mock).
+
+You can use the [mockery tool](http://github.com/vektra/mockery) to autogenerate the mock code against an interface as well, making using mocks much quicker.
+
+[`suite`](http://godoc.org/github.com/stretchr/testify/suite "API documentation") package
+-----------------------------------------------------------------------------------------
+
+The `suite` package provides functionality that you might be used to from more common object oriented languages. With it, you can build a testing suite as a struct, build setup/teardown methods and testing methods on your struct, and run them with 'go test' as per normal.
+
+An example suite is shown below:
+
+```go
+// Basic imports
+import (
+ "testing"
+ "github.com/stretchr/testify/assert"
+ "github.com/stretchr/testify/suite"
+)
+
+// Define the suite, and absorb the built-in basic suite
+// functionality from testify - including a T() method which
+// returns the current testing context
+type ExampleTestSuite struct {
+ suite.Suite
+ VariableThatShouldStartAtFive int
+}
+
+// Make sure that VariableThatShouldStartAtFive is set to five
+// before each test
+func (suite *ExampleTestSuite) SetupTest() {
+ suite.VariableThatShouldStartAtFive = 5
+}
+
+// All methods that begin with "Test" are run as tests within a
+// suite.
+func (suite *ExampleTestSuite) TestExample() {
+ assert.Equal(suite.T(), 5, suite.VariableThatShouldStartAtFive)
+}
+
+// In order for 'go test' to run this suite, we need to create
+// a normal test function and pass our suite to suite.Run
+func TestExampleTestSuite(t *testing.T) {
+ suite.Run(t, new(ExampleTestSuite))
+}
+```
+
+For a more complete example, using all of the functionality provided by the suite package, look at our [example testing suite](https://github.com/stretchr/testify/blob/master/suite/suite_test.go)
+
+For more information on writing suites, check out the [API documentation for the `suite` package](http://godoc.org/github.com/stretchr/testify/suite).
+
+`Suite` object has assertion methods:
+
+```go
+// Basic imports
+import (
+ "testing"
+ "github.com/stretchr/testify/suite"
+)
+
+// Define the suite, and absorb the built-in basic suite
+// functionality from testify - including assertion methods.
+type ExampleTestSuite struct {
+ suite.Suite
+ VariableThatShouldStartAtFive int
+}
+
+// Make sure that VariableThatShouldStartAtFive is set to five
+// before each test
+func (suite *ExampleTestSuite) SetupTest() {
+ suite.VariableThatShouldStartAtFive = 5
+}
+
+// All methods that begin with "Test" are run as tests within a
+// suite.
+func (suite *ExampleTestSuite) TestExample() {
+ suite.Equal(suite.VariableThatShouldStartAtFive, 5)
+}
+
+// In order for 'go test' to run this suite, we need to create
+// a normal test function and pass our suite to suite.Run
+func TestExampleTestSuite(t *testing.T) {
+ suite.Run(t, new(ExampleTestSuite))
+}
+```
+

+// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
+//
+// Example Usage
+//
+// The following is a complete example using assert in a standard test function:
+// import (
+// "testing"
+// "github.com/stretchr/testify/assert"
+// )
+//
+// func TestSomething(t *testing.T) {
+//
+// var a string = "Hello"
+// var b string = "Hello"
+//
+// assert.Equal(t, a, b, "The two words should be the same.")
+//
+// }
+//
+// if you assert many times, use the format below:
+//
+// import (
+// "testing"
+// "github.com/stretchr/testify/assert"
+// )
+//
+// func TestSomething(t *testing.T) {
+// assert := assert.New(t)
+//
+// var a string = "Hello"
+// var b string = "Hello"
+//
+// assert.Equal(a, b, "The two words should be the same.")
+// }
+//
+// Assertions
+//
+// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
+// All assertion functions take, as the first argument, the `*testing.T` object provided by the
+// testing framework. This allows the assertion funcs to write the failings and other details to
+// the correct place.
+//
+// Every assertion function also takes an optional string message as the final argument,
+// allowing custom error messages to be appended to the message the assertion method outputs.

+// Package mock provides a system by which it is possible to mock your objects
+// and verify calls are happening as expected.
+//
+// Example Usage
+//
+// The mock package provides an object, Mock, that tracks activity on another object. It is usually
+// embedded into a test object as shown below:
+//
+// type MyTestObject struct {
+// // add a Mock object instance
+// mock.Mock
+//
+// // other fields go here as normal
+// }
+//
+// When implementing the methods of an interface, you wire your functions up
+// to call the Mock.Called(args...) method, and return the appropriate values.
+//
+// For example, to mock a method that saves the name and age of a person and returns
+// the year of their birth or an error, you might write this:
+//
+// func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
+// args := o.Called(firstname, lastname, age)
+// return args.Int(0), args.Error(1)
+// }
+//
+// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
+// index position. Given this argument list:
+//
+// (12, true, "Something")
+//
+// You could read them out strongly typed like this:
+//
+// args.Int(0)
+// args.Bool(1)
+// args.String(2)
+//
+// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
+//
+// return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
+//
+// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
+// cases you should check for nil first.

+// Package require implements the same assertions as the `assert` package but
+// stops test execution when a test fails.
+//
+// Example Usage
+//
+// The following is a complete example using require in a standard test function:
+// import (
+// "testing"
+// "github.com/stretchr/testify/require"
+// )
+//
+// func TestSomething(t *testing.T) {
+//
+// var a string = "Hello"
+// var b string = "Hello"
+//
+// require.Equal(t, a, b, "The two words should be the same.")
+//
+// }
+//
+// Assertions
+//
+// The `require` package have same global functions as in the `assert` package,
+// but instead of returning a boolean result they call `t.FailNow()`.
+//
+// Every assertion function also takes an optional string message as the final argument,
+// allowing custom error messages to be appended to the message the assertion method outputs.

+// Package suite contains logic for creating testing suite structs
+// and running the methods on those structs as tests. The most useful
+// piece of this package is that you can create setup/teardown methods
+// on your testing suites, which will run before/after the whole suite
+// or individual tests (depending on which interface(s) you
+// implement).
+//
+// A testing suite is usually built by first extending the built-in
+// suite functionality from suite.Suite in testify. Alternatively,
+// you could reproduce that logic on your own if you wanted (you
+// just need to implement the TestingSuite interface from
+// suite/interfaces.go).
+//
+// After that, you can implement any of the interfaces in
+// suite/interfaces.go to add setup/teardown functionality to your
+// suite, and add any methods that start with "Test" to add tests.
+// Methods that do not match any suite interfaces and do not begin
+// with "Test" will not be run by testify, and can safely be used as
+// helper methods.
+//
+// Once you've built your testing suite, you need to run the suite
+// (using suite.Run from testify) inside any function that matches the
+// identity that "go test" is already looking for (i.e.
+// func(*testing.T)).
+//
+// Regular expression to select test suites specified command-line
+// argument "-run". Regular expression to select the methods
+// of test suites specified command-line argument "-m".
+// Suite object has assertion methods.
+//
+// A crude example:
+// // Basic imports
+// import (
+// "testing"
+// "github.com/stretchr/testify/assert"
+// "github.com/stretchr/testify/suite"
+// )
+//
+// // Define the suite, and absorb the built-in basic suite
+// // functionality from testify - including a T() method which
+// // returns the current testing context
+// type ExampleTestSuite struct {
+// suite.Suite
+// VariableThatShouldStartAtFive int
+// }
+//
+// // Make sure that VariableThatShouldStartAtFive is set to five
+// // before each test
+// func (suite *ExampleTestSuite) SetupTest() {
+// suite.VariableThatShouldStartAtFive = 5
+// }
+//
+// // All methods that begin with "Test" are run as tests within a
+// // suite.
+// func (suite *ExampleTestSuite) TestExample() {
+// assert.Equal(suite.T(), 5, suite.VariableThatShouldStartAtFive)
+// suite.Equal(5, suite.VariableThatShouldStartAtFive)
+// }
+//
+// // In order for 'go test' to run this suite, we need to create

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+ * Pointers are dereferenced and followed
+ * Circular data structures are detected and handled properly
+ * Custom Stringer/error interfaces are optionally invoked, including
+ on unexported types
+ * Custom types which only implement the Stringer/error interfaces via
+ a pointer receiver are optionally invoked when passing non-pointer
+ variables
+ * Byte arrays and slices are dumped like the hexdump -C command which
+ includes offsets, byte values in hex, and ASCII output (only when using
+ Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+ * Dump style which prints with newlines, customizable indentation,
+ and additional debug information such as types and all pointer addresses
+ used to indirect to the final value
+ * A custom Formatter interface that integrates cleanly with the standard fmt
+ package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+ similar to the default %v while providing the additional functionality
+ outlined above and passing unsupported format verbs such as %x and %q
+ along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew. See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+ spew.Dump(myVar1, myVar2, ...)
+ spew.Fdump(someWriter, myVar1, myVar2, ...)
+ str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+ spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+ spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+The following configuration options are available:
+ * Indent
+ String to use for each indentation level for Dump functions.
+ It is a single space by default. A popular alternative is "\t".
+
+ * MaxDepth
+ Maximum number of levels to descend into nested data structures.
+ There is no limit by default.
+
+ * DisableMethods
+ Disables invocation of error and Stringer interface methods.
+ Method invocation is enabled by default.
+
+ * DisablePointerMethods
+ Disables invocation of error and Stringer interface methods on types
+ which only accept pointer receivers from non-pointer variables.
+ Pointer method invocation is enabled by default.
+
+ * ContinueOnMethod
+ Enables recursion into types after invoking error and Stringer interface
+ methods. Recursion after method invocation is disabled by default.
+
+ * SortKeys
+ Specifies map keys should be sorted before being printed. Use
+ this to have a more deterministic, diffable output. Note that
+ only native types (bool, int, uint, floats, uintptr and string)
+ and types which implement error or Stringer interfaces are
+ supported with other types sorted according to the
+ reflect.Value.String() output which guarantees display
+ stability. Natural map order is used by default.
+
+ * SpewKeys
+ Specifies that, as a last resort attempt, map keys should be
+ spewed to strings and sorted by those strings. This is only
+ considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+ spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer. For example, to dump to standard error:
+
+ spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+ str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+ (main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+ flag: (main.Flag) flagTwo,
+ data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) (len=1) {
+ (string) (len=3) "one": (bool) true
+ }
+ }
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+ ([]uint8) (len=32 cap=32) {
+ 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
+ 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
+ 00000020 31 32 |12|
+ }
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations. Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting. In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
+functions have syntax you are most likely already familiar with:
+
+ spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+ spew.Println(myVar, myVar2)
+ spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+ %v: <**>5
+ %+v: <**>(0xf8400420d0->0xf8400420c8)5
+ %#v: (**uint8)5
+ %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+ %v: <*>{1 <*><shown>}
+ %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+ %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+ %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output. Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+// SequenceMatcher compares sequence of strings. The basic
+// algorithm predates, and is a little fancier than, an algorithm
+// published in the late 1980's by Ratcliff and Obershelp under the
+// hyperbolic name "gestalt pattern matching". The basic idea is to find
+// the longest contiguous matching subsequence that contains no "junk"
+// elements (R-O doesn't address junk). The same idea is then applied
+// recursively to the pieces of the sequences to the left and to the right
+// of the matching subsequence. This does not yield minimal edit
+// sequences, but does tend to yield matches that "look right" to people.
+//
+// SequenceMatcher tries to compute a "human-friendly diff" between two
+// sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
+// longest *contiguous* & junk-free matching subsequence. That's what
+// catches peoples' eyes. The Windows(tm) windiff has another interesting
+// notion, pairing up elements that appear uniquely in each sequence.
+// That, and the method here, appear to yield more intuitive difference
+// reports than does diff. This method appears to be the least vulnerable
+// to synching up on blocks of "junk lines", though (like blank lines in
+// ordinary text files, or maybe "<P>" lines in HTML files). That may be
+// because this is the only method of the 3 that has a *concept* of
+// "junk" <wink>.
+//
+// Timing: Basic R-O is cubic time worst case and quadratic time expected
+// case. SequenceMatcher is quadratic time for the worst case and has
+// expected-case behavior dependent in a complicated way on how many
+// elements the sequences have in common; best case time is linear.

+// objx - Go package for dealing with maps, slices, JSON and other data.
+//
+// Overview
+//
+// Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes
+// a powerful `Get` method (among others) that allows you to easily and quickly get
+// access to data within the map, without having to worry too much about type assertions,
+// missing data, default values etc.
+//
+// Pattern
+//
+// Objx uses a preditable pattern to make access data from within `map[string]interface{}'s
+// easy.
+//
+// Call one of the `objx.` functions to create your `objx.Map` to get going:
+//
+// m, err := objx.FromJSON(json)
+//
+// NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong,
+// the rest will be optimistic and try to figure things out without panicking.
+//
+// Use `Get` to access the value you're interested in. You can use dot and array
+// notation too:
+//
+// m.Get("places[0].latlng")
+//
+// Once you have saught the `Value` you're interested in, you can use the `Is*` methods
+// to determine its type.
+//
+// if m.Get("code").IsStr() { /* ... */ }
+//
+// Or you can just assume the type, and use one of the strong type methods to
+// extract the real value:
+//
+// m.Get("code").Int()
+//
+// If there's no value there (or if it's the wrong type) then a default value
+// will be returned, or you can be explicit about the default value.
+//
+// Get("code").Int(-1)
+//
+// If you're dealing with a slice of data as a value, Objx provides many useful
+// methods for iterating, manipulating and selecting that data. You can find out more
+// by exploring the index below.
+//
+// Reading data
+//
+// A simple example of how to use Objx:
+//
+// // use MustFromJSON to make an objx.Map from some JSON
+// m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
+//
+// // get the details
+// name := m.Get("name").Str()
+// age := m.Get("age").Int()
+//
+// // get their nickname (or use their name if they
+// // don't have one)
+// nickname := m.Get("nickname").Str(name)
+//
+// Ranging
+//
+// Since `objx.Map` is a `map[string]interface{}` you can treat it as such. For
+// example, to `range` the data, do what you would expect:
+//
+// m := objx.MustFromJSON(json)
+// for key, value := range m {
+//
+// /* ... do your magic ... */
+//
+// }
