NewFormatter returns a custom formatter that satisfies the fmt.Formatter

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), and %#+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).
Typically this function shouldn't be called directly. It is much easier to make
use of the custom formatter by calling one of the convenience functions such as

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.
* DisablePointerAddresses
DisablePointerAddresses specifies whether to disable the printing of
pointer addresses. This is useful when diffing data structures in tests.
* DisableCapacities
DisableCapacities specifies whether to disable the printing of
capacities for arrays, slices, maps and channels. This is useful when
diffing data structures in tests.
* 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.

NewFormatter returns a custom formatter that satisfies the fmt.Formatter
interface. As a result, 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).
Typically this function shouldn't be called directly. It is much easier to make
use of the custom formatter by calling one of the convenience functions such as
Printf, Println, or Fprintf.

/*
Package restful , a lean package for creating REST-style WebServices without magic.
WebServices and Routes
A WebService has a collection of Route objects that dispatch incoming Http Requests to a function calls.
Typically, a WebService has a root path (e.g. /users) and defines common MIME types for its routes.
WebServices must be added to a container (see below) in order to handler Http requests from a server.
A Route is defined by a HTTP method, an URL path and (optionally) the MIME types it consumes (Content-Type) and produces (Accept).
This package has the logic to find the best matching Route and if found, call its Function.
ws := new(restful.WebService)
ws.
Path("/users").
Consumes(restful.MIME_JSON, restful.MIME_XML).
Produces(restful.MIME_JSON, restful.MIME_XML)
ws.Route(ws.GET("/{user-id}").To(u.findUser)) // u is a UserResource
...
// GET http://localhost:8080/users/1
func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
id := request.PathParameter("user-id")
...
}
The (*Request, *Response) arguments provide functions for reading information from the request and writing information back to the response.
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-user-resource.go with a full implementation.
Regular expression matching Routes
A Route parameter can be specified using the format "uri/{var[:regexp]}" or the special version "uri/{var:*}" for matching the tail of the path.
For example, /persons/{name:[A-Z][A-Z]} can be used to restrict values for the parameter "name" to only contain capital alphabetic characters.
Regular expressions must use the standard Go syntax as described in the regexp package. (https://code.google.com/p/re2/wiki/Syntax)
This feature requires the use of a CurlyRouter.
Containers
A Container holds a collection of WebServices, Filters and a http.ServeMux for multiplexing http requests.
Using the statements "restful.Add(...) and restful.Filter(...)" will register WebServices and Filters to the Default Container.
The Default container of go-restful uses the http.DefaultServeMux.
You can create your own Container and create a new http.Server for that particular container.
container := restful.NewContainer()
server := &http.Server{Addr: ":8081", Handler: container}
Filters
A filter dynamically intercepts requests and responses to transform or use the information contained in the requests or responses.
You can use filters to perform generic logging, measurement, authentication, redirect, set response headers etc.
In the restful package there are three hooks into the request,response flow where filters can be added.
Each filter must define a FilterFunction:
func (req *restful.Request, resp *restful.Response, chain *restful.FilterChain)
Use the following statement to pass the request,response pair to the next filter or RouteFunction
chain.ProcessFilter(req, resp)
Container Filters
These are processed before any registered WebService.
// install a (global) filter for the default container (processed before any webservice)
restful.Filter(globalLogging)
WebService Filters
These are processed before any Route of a WebService.
// install a webservice filter (processed before any route)
ws.Filter(webserviceLogging).Filter(measureTime)
Route Filters
These are processed before calling the function associated with the Route.
// install 2 chained route filters (processed before calling findUser)
ws.Route(ws.GET("/{user-id}").Filter(routeLogging).Filter(NewCountFilter().routeCounter).To(findUser))
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-filters.go with full implementations.
Response Encoding
Two encodings are supported: gzip and deflate. To enable this for all responses:
restful.DefaultContainer.EnableContentEncoding(true)
If a Http request includes the Accept-Encoding header then the response content will be compressed using the specified encoding.
Alternatively, you can create a Filter that performs the encoding and install it per WebService or Route.
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-encoding-filter.go
OPTIONS support
By installing a pre-defined container filter, your Webservice(s) can respond to the OPTIONS Http request.
Filter(OPTIONSFilter())
CORS
By installing the filter of a CrossOriginResourceSharing (CORS), your WebService(s) can handle CORS requests.
cors := CrossOriginResourceSharing{ExposeHeaders: []string{"X-My-Header"}, CookiesAllowed: false, Container: DefaultContainer}
Filter(cors.Filter)
Error Handling
Unexpected things happen. If a request cannot be processed because of a failure, your service needs to tell via the response what happened and why.
For this reason HTTP status codes exist and it is important to use the correct code in every exceptional situation.
400: Bad Request
If path or query parameters are not valid (content or type) then use http.StatusBadRequest.
404: Not Found
Despite a valid URI, the resource requested may not be available
500: Internal Server Error
If the application logic could not process the request (or write the response) then use http.StatusInternalServerError.
405: Method Not Allowed
The request has a valid URL but the method (GET,PUT,POST,...) is not allowed.
406: Not Acceptable
The request does not have or has an unknown Accept Header set for this operation.
415: Unsupported Media Type
The request does not have or has an unknown Content-Type Header set for this operation.
ServiceError
In addition to setting the correct (error) Http status code, you can choose to write a ServiceError message on the response.
Performance options
This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
restful.DefaultContainer.DoNotRecover(false)
DoNotRecover controls whether panics will be caught to return HTTP 500.
If set to false, the container will recover from panics.
Default value is true
restful.SetCompressorProvider(NewBoundedCachedCompressors(20, 20))
If content encoding is enabled then the default strategy for getting new gzip/zlib writers and readers is to use a sync.Pool.
Because writers are expensive structures, performance is even more improved when using a preloaded cache. You can also inject your own implementation.
Trouble shooting
This package has the means to produce detail logging of the complete Http request matching process and filter invocation.
Enabling this feature requires you to set an implementation of restful.StdLogger (e.g. log.Logger) instance such as:
restful.TraceLogger(log.New(os.Stdout, "[restful] ", log.LstdFlags|log.Lshortfile))
Logging
The restful.SetLogger() method allows you to override the logger used by the package. By default restful
uses the standard library `log` package and logs to stdout. Different logging packages are supported as
long as they conform to `StdLogger` interface defined in the `log` sub-package, writing an adapter for your
preferred package is simple.

// Parameter a unique parameter is defined by a combination of a [name](#parameterName) and [location](#parameterIn).
//
// There are five possible parameter types.
// * Path - Used together with [Path Templating](#pathTemplating), where the parameter value is actually part of the operation's URL. This does not include the host or base path of the API. For example, in `/items/{itemId}`, the path parameter is `itemId`.
// * Query - Parameters that are appended to the URL. For example, in `/items?id=###`, the query parameter is `id`.
// * Header - Custom headers that are expected as part of the request.
// * Body - The payload that's appended to the HTTP request. Since there can only be one payload, there can only be *one* body parameter. The name of the body parameter has no effect on the parameter itself and is used for documentation purposes only. Since Form parameters are also in the payload, body and form parameters cannot exist together for the same operation.
// * Form - Used to describe the payload of an HTTP request when either `application/x-www-form-urlencoded` or `multipart/form-data` are used as the content type of the request (in Swagger's definition, the [`consumes`](#operationConsumes) property of an operation). This is the only parameter type that can be used to send files, thus supporting the `file` type. Since form parameters are sent in the payload, they cannot be declared together with a body parameter for the same operation. Form parameters have a different format based on the content-type used (for further details, consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4):
// * `application/x-www-form-urlencoded` - Similar to the format of Query parameters but as a payload. For example, `foo=1&bar=swagger` - both `foo` and `bar` are form parameters. This is normally used for simple parameters that are being transferred.
// * `multipart/form-data` - each parameter takes a section in the payload with an internal header. For example, for the header `Content-Disposition: form-data; name="submit-name"` the name of the parameter is `submit-name`. This type of form parameters is more commonly used for file transfers.
