-## Functions
-
-### Date Functions
-
-- date: Format a date, where a date is an integer type or a time.Time type, and
-  format is a time.Format formatting string.
-- dateModify: Given a date, modify it with a duration: `date_modify "-1.5h" now`. If the duration doesn't
-parse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.
-- now: Current time.Time, for feeding into date-related functions.
-- htmlDate: Format a date for use in the value field of an HTML "date" form element.
-- dateInZone: Like date, but takes three arguments: format, timestamp,
-  timezone.
-- htmlDateInZone: Like htmlDate, but takes two arguments: timestamp,
-  timezone.
-
-### String Functions
-
-- trim: strings.TrimSpace
-- trimAll: strings.Trim, but with the argument order reversed `trimAll "$" "$5.00"` or `"$5.00 | trimAll "$"`
-- trimSuffix: strings.TrimSuffix, but with the argument order reversed `trimSuffix "-" "5-"`
-- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
-- upper: strings.ToUpper
-- lower: strings.ToLower
-- title: strings.Title
-- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
-- substr: Given string, start, and length, return a substr.
-- nospace: Remove all spaces from a string. `h e l l o` becomes
-  `hello`.
-- abbrev: Truncate a string with ellipses
-- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
-- abbrevboth: Truncate both sides of a string with ellipses
-- untitle: Remove title case
-- intials: Given multiple words, return the first letter of each
-  word
-- randAlphaNum: Generate a random alpha-numeric string
-- randAlpha: Generate a random alphabetic string
-- randAscii: Generate a random ASCII string, including symbols
-- randNumeric: Generate a random numeric string
-- wrap: Wrap text at the given column count
-- wrapWith: Wrap text at the given column count, and with the given
-  string for a line terminator: `wrap 50 "\n\t" $string`
-- contains: strings.Contains, but with the arguments switched: `contains "cat" "uncatch"`. (This simplifies common pipelines)
-- hasPrefix: strings.hasPrefix, but with the arguments switched: `hasPrefix "cat" "catch"`.
-- hasSuffix: strings.hasSuffix, but with the arguments switched: `hasSuffix "cat" "ducat"`.
-- quote: Wrap strings in double quotes. `quote "a" "b"` returns `"a"
-  "b"`
-- squote: Wrap strings in single quotes.
-- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.
-- indent: Indent a string using space characters. `indent 4 "foo\nbar"` produces "    foo\n    bar"
-- replace: Replace an old with a new in a string: `$name | replace " " "-"`
-- plural: Choose singular or plural based on length: `len $fish | plural
-  "one anchovy" "many anchovies"`
-- uuidv4: Generate a UUID v4 string
-- sha256sum: Generate a hex encoded sha256 hash of the input
-- toString: Convert something to a string
-
-### String Slice Functions:
-
-- join: strings.Join, but as `join SEP SLICE`
-- split: strings.Split, but as `split SEP STRING`. The results are returned
-  as a map with the indexes set to _N, where N is an integer starting from 0.
-  Use it like this: `{{$v := "foo/bar/baz" | split "/"}}{{$v._0}}` (Prints `foo`)
-- splitList: strings.Split, but as `split SEP STRING`. The results are returned
-  as an array.
-- toStrings: convert a list to a list of strings. 'list 1 2 3 | toStrings' produces '["1" "2" "3"]'
-- sortAlpha: sort a list lexicographically.
-
-### Integer Slice Functions:
-
-- until: Given an integer, returns a slice of counting integers from 0 to one
-	  less than the given integer: `range $i, $e := until 5`
-- untilStep: Given start, stop, and step, return an integer slice starting at
-	  'start', stopping at `stop`, and incrementing by 'step'. This is the same
-	  as Python's long-form of 'range'.
-
-### Conversions:
-
-- atoi: Convert a string to an integer. 0 if the integer could not be parsed.
-- int: Convert a string or numeric to an int
-- int64: Convert a string or numeric to an int64
-- float64: Convert a string or numeric to a float64
-
-### Defaults:
-
-- default: Give a default value. Used like this: {{trim "   "| default "empty"}}.
-  Since trim produces an empty string, the default value is returned. For
-  things with a length (strings, slices, maps), len(0) will trigger the default.
-  For numbers, the value 0 will trigger the default. For booleans, false will
-  trigger the default. For structs, the default is never returned (there is
-  no clear empty condition). For everything else, nil value triggers a default.
-- empty: Returns true if the given value is the zero value for that
-  type. Structs are always non-empty.
-- coalesce: Given a list of items, return the first non-empty one.
-  This follows the same rules as 'empty'. `{{ coalesce .someVal 0 "hello" }}`
-  will return `.someVal` if set, or else return "hello". The 0 is skipped
-  because it is an empty value.
-- compact: Return a copy of a list with all of the empty values removed.
-  `list 0 1 2 "" | compact` will return `[1 2]`
-
-### OS:
-
-- env: Read an environment variable.
-- expandenv: Expand all environment variables in a string.
-
-### File Paths:
-- base: Return the last element of a path. https://golang.org/pkg/path#Base
-- dir: Remove the last element of a path. https://golang.org/pkg/path#Dir
-- clean: Clean a path to the shortest equivalent name.  (e.g. remove "foo/.."
-  from "foo/../bar.html") https://golang.org/pkg/path#Clean
-- ext: Get the extension for a file path: https://golang.org/pkg/path#Ext
-- isAbs: Returns true if a path is absolute: https://golang.org/pkg/path#IsAbs
-
-### Encoding:
-
-- b32enc: Encode a string into a Base32 string
-- b32dec: Decode a string from a Base32 string
-- b64enc: Encode a string into a Base64 string
-- b64dec: Decode a string from a Base64 string
-
-### Data Structures:
-
-- tuple: Takes an arbitrary list of items and returns a slice of items. Its
-  tuple-ish properties are mainly gained through the template idiom, and not
-  through an API provided here. WARNING: The implementation of tuple will
-  change in the future.
-- list: An arbitrary ordered list of items. (This is prefered over tuple.)
-- dict: Takes a list of name/values and returns a map[string]interface{}.
-  The first parameter is converted to a string and stored as a key, the
-  second parameter is treated as the value. And so on, with odds as keys and
-  evens as values. If the function call ends with an odd, the last key will
-  be assigned the empty string. Non-string keys are converted to strings as
-  follows: []byte are converted, fmt.Stringers will have String() called.
-  errors will have Error() called. All others will be passed through
-  fmt.Sprtinf("%v"). _dicts are unordered_.
-
-List:
-
-```
-{{$t := list 1 "a" "foo"}}
-{{index $t 2}}{{index $t 0 }}{{index $t 1}}
-{{/* Prints foo1a *}}
-```
-
-Dict:
-```
-{{ $t := map "key1" "value1" "key2" "value2" }}
-{{ $t.key2 }}
-{{ /* Prints value2 *}}
-```
-
-
-### Lists Functions:
-
-These are used to manipulate lists: `{{ list 1 2 3 | reverse | first }}`
-
-- first: Get the first item in a 'list'. 'list 1 2 3 | first' prints '1'
-- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'
-- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'
-- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'
-- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'
-- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.
-- reverse: Reverse the items in a list.
-- uniq: Remove duplicates from a list.
-- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'
-- has: Return 'tru' if the item is found in the list: 'has "foo" $list' will return 'true' if the list contains "foo"
-
-### Dict Functions:
-
-These are used to manipulate dicts.
-
-- set: Takes a dict, a key, and a value, and sets that key/value pair in
-  the dict. `set $dict $key $value`. For convenience, it returns the dict,
-  even though the dict was modified in place.
-- unset: Takes a dict and a key, and deletes that key/value pair from the
-  dict. `unset $dict $key`. This returns the dict for convenience.
-- hasKey: Takes a dict and a key, and returns boolean true if the key is in
-  the dict.
-- pluck: Given a key and one or more maps, get all of the values for that key.
-- keys: Get an array of all of the keys in a dict. Order is not guaranteed.
-- pick: Select just the given keys out of the dict, and return a new dict.
-- omit: Return a dict without the given keys.
-
-### Reflection:
-
-- typeOf: Takes an interface and returns a string representation of the type.
-  For pointers, this will return a type prefixed with an asterisk(`*`). So
-  a pointer to type `Foo` will be `*Foo`.
-- typeIs: Compares an interface with a string name, and returns true if they match.
-  Note that a pointer will not match a reference. For example `*Foo` will not
-  match `Foo`.
-- typeIsLike: returns true if the interface is of the given type, or
-  is a pointer to the given type.
-- kindOf: Takes an interface and returns a string representation of its kind.
-- kindIs: Returns true if the given string matches the kind of the given interface.
-
-	Note: None of these can test whether or not something implements a given
-	interface, since doing so would require compiling the interface in ahead of
-	time.
-
-
-### Math Functions:
-
-Integer functions will convert integers of any width to `int64`. If a
-string is passed in, functions will attempt to conver with
-`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
-
-- add1: Increment an integer by 1
-- add: Sum integers. `add 1 2 3` renders `6`
-- sub: Subtract the second integer from the first
-- div: Divide the first integer by the second
-- mod: Module of first integer divided by second
-- mul: Multiply integers integers
-- max (biggest): Return the biggest of a series of integers. `max 1 2 3`
-  returns `3`.
-- min: Return the smallest of a series of integers. `min 1 2 3` returns
-  `1`.
-
-### Cryptographic Functions:
-
-- derivePassword: Derive a password from the given parameters according to the "Master Password" algorithm (http://masterpasswordapp.com/algorithm.html)
-  Given parameters (in order) are:
-      `counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,
-       `user`, and `site`. The following line generates a long password for the user "user" and with a master-password "password"  on the site "example.com":
-       ```
-       {{ derivePassword 1 "long" "password" "user" "example.com" }}
-       ```
-
-## SemVer Functions:
-
-These functions provide version parsing and comparisons for SemVer 2 version
-strings.
-
-- semver: Parse a semantic version and return a Version object.
-- semverCompare: Compare a SemVer range to a particular version.
-
 ## Principles:
 
 The following principles were used in deciding on which functions to add, and

 # package log

-logging, and so on. It can be used for both typical application log events,

+It may be wrapped to encode conventions, enforce type-safety, provide leveled logging, and so on.

 ## Structured logging
 
-Structured logging is, basically, conceding to the reality that logs are
-_data_, and warrant some level of schematic rigor. Using a stricter,
-key/value-oriented message format for our logs, containing contextual and
-semantic information, makes it much easier to get insight into the
-operational activity of the systems we build. Consequently, `package log` is
-of the strong belief that "[the benefits of structured logging outweigh the
-minimal effort involved](https://www.thoughtworks.com/radar/techniques/structured-logging)".

-// Package metrics provides a framework for application instrumentation. It's
-// primarily designed to help you get started with good and robust
-// instrumentation, and to help you migrate from a less-capable system like

 //
-// This package provides three core metric abstractions (Counter, Gauge, and
-// Histogram) and implementations for almost all common instrumentation
-// backends. Each metric has an observation method (Add, Set, or Observe,
-// respectively) used to record values, and a With method to "scope" the
-// observation by various parameters. For example, you might have a Histogram to
-// record request durations, parameterized by the method that's being called.
-//
-//    var requestDuration metrics.Histogram
-//    // ...
-//    requestDuration.With("method", "MyMethod").Observe(time.Since(begin))
-//
-// This allows a single high-level metrics object (requestDuration) to work with
-// many code paths somewhat dynamically. The concept of With is fully supported
-// in some backends like Prometheus, and not supported in other backends like
-// Graphite. So, With may be a no-op, depending on the concrete implementation
-// you choose. Please check the implementation to know for sure. For
-// implementations that don't provide With, it's necessary to fully parameterize
-// each metric in the metric name, e.g.
-//
-//    // Statsd
-//    c := statsd.NewCounter("request_duration_MyMethod_200")
-//    c.Add(1)
-//
-//    // Prometheus
-//    c := prometheus.NewCounter(stdprometheus.CounterOpts{

+====
+
+Leveled execution logs for Go.
+
+This is an efficient pure Go implementation of leveled logs in the
+manner of the open source C++ package
+	https://github.com/google/glog
+
+By binding methods to booleans it is possible to use the log package
+without paying the expense of evaluating the arguments to the log.
+Through the -vmodule flag, the package also provides fine-grained
+control over logging at the file level.
+
+The comment from glog.go introduces the ideas:
+
+	Package glog implements logging analogous to the Google-internal
+	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
+	Error, Fatal, plus formatting variants such as Infof. It
+	also provides V-style logging controlled by the -v and
+	-vmodule=file=2 flags.
+	
+	Basic examples:
+	
+		glog.Info("Prepare to repel boarders")
+	
+		glog.Fatalf("Initialization failed: %s", err)
+	
+	See the documentation for the V function for an explanation
+	of these examples:
+	
+		if glog.V(2) {
+			glog.Info("Starting transaction...")
+		}
+	
+		glog.V(2).Infoln("Processed", nItems, "elements")
+
+
+The repository contains an open source version of the log package
+used inside Google. The master copy of the source lives inside
+Google, not here. The code in this repo is for export only and is not itself
+under development. Feature requests will be ignored.
+
+Send bug reports to golang-nuts@googlegroups.com.

+//	-alsologtostderr=false
+//		Logs are written to standard error as well as to files.

+//
+//	Other flags provide aids to debugging.
+//
+//	-log_backtrace_at=""
+//		When set to a file and line number holding a logging statement,
+//		such as
+//			-log_backtrace_at=gopherflakes.go:234
+//		a stack trace will be written to the Info log whenever execution
+//		hits that statement. (Unlike with -vmodule, the ".go" must be
+//		present.)
+//	-v=0
+//		Enable V-leveled logging at the specified level.
+//	-vmodule=""
+//		The syntax of the argument is a comma-separated list of pattern=N,
+//		where pattern is a literal file name (minus the ".go" suffix) or
+//		"glob" pattern and N is a V level. For instance,
+//			-vmodule=gopher*=3
+//		sets the V level to 3 in all Go files whose names begin "gopher".

+# grpc-gateway
+
+[![Build Status](https://travis-ci.org/grpc-ecosystem/grpc-gateway.svg?branch=master)](https://travis-ci.org/grpc-ecosystem/grpc-gateway)
+
+grpc-gateway is a plugin of [protoc](http://github.com/google/protobuf).
+It reads [gRPC](http://github.com/grpc/grpc-common) service definition,
+and generates a reverse-proxy server which translates a RESTful JSON API into gRPC.
+This server is generated according to [custom options](https://cloud.google.com/service-management/reference/rpc/google.api#http) in your gRPC definition.
+
+It helps you to provide your APIs in both gRPC and RESTful style at the same time.
+
+![architecture introduction diagram](https://docs.google.com/drawings/d/12hp4CPqrNPFhattL_cIoJptFvlAqm5wLQ0ggqI5mkCg/pub?w=749&amp;h=370)
+
+## Background
+gRPC is great -- it generates API clients and server stubs in many programming languages, it is fast, easy-to-use, bandwidth-efficient and its design is combat-proven by Google.
+However, you might still want to provide a traditional RESTful API as well. Reasons can range from maintaining backwards-compatibility, supporting languages or clients not well supported by gRPC to simply maintaining the aesthetics and tooling involved with a RESTful architecture.
+
+This project aims to provide that HTTP+JSON interface to your gRPC service. A small amount of configuration in your service to attach HTTP semantics is all that's needed to generate a reverse-proxy with this library.
+
+## Installation
+First you need to install ProtocolBuffers 3.0.0-beta-3 or later.
+
+```sh
+mkdir tmp
+cd tmp
+git clone https://github.com/google/protobuf
+cd protobuf
+./autogen.sh
+./configure
+make
+make check
+sudo make install
+```
+
+Then, `go get -u` as usual the following packages:
+
+```sh
+go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway
+go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger
+go get -u github.com/golang/protobuf/protoc-gen-go
+```
+ 
+## Usage
+Make sure that your `$GOPATH/bin` is in your `$PATH`.
+
+1. Define your service in gRPC
+   
+   your_service.proto:
+   ```protobuf
+   syntax = "proto3";
+   package example;
+   message StringMessage {
+     string value = 1;
+   }
+   
+   service YourService {
+     rpc Echo(StringMessage) returns (StringMessage) {}
+   }
+   ```
+2. Add a [custom option](https://cloud.google.com/service-management/reference/rpc/google.api#http) to the .proto file
+   
+   your_service.proto:
+   ```diff
+    syntax = "proto3";
+    package example;
+   +
+   +import "google/api/annotations.proto";
+   +
+    message StringMessage {
+      string value = 1;
+    }
+    
+    service YourService {
+   -  rpc Echo(StringMessage) returns (StringMessage) {}
+   +  rpc Echo(StringMessage) returns (StringMessage) {
+   +    option (google.api.http) = {
+   +      post: "/v1/example/echo"
+   +      body: "*"
+   +    };
+   +  }
+    }
+   ```
+3. Generate gRPC stub
+   
+   ```sh
+   protoc -I/usr/local/include -I. \
+     -I$GOPATH/src \
+     -I$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis \
+     --go_out=plugins=grpc:. \
+     path/to/your_service.proto
+   ```
+   
+   It will generate a stub file `path/to/your_service.pb.go`.
+4. Implement your service in gRPC as usual
+   1. (Optional) Generate gRPC stub in the language you want.
+     
+     e.g.
+     ```sh
+     protoc -I/usr/local/include -I. \
+       -I$GOPATH/src \
+       -I$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis \
+       --ruby_out=. \
+       path/to/your/service_proto
+     
+     protoc -I/usr/local/include -I. \
+       -I$GOPATH/src \
+       -I$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis \
+       --plugin=protoc-gen-grpc=grpc_ruby_plugin \
+       --grpc-ruby_out=. \
+       path/to/your/service.proto
+     ```
+   2. Add the googleapis-common-protos gem (or your language equivalent) as a dependency to your project.
+   3. Implement your service
+   
+5. Generate reverse-proxy
+   
+   ```sh
+   protoc -I/usr/local/include -I. \
+     -I$GOPATH/src \
+     -I$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis \
+     --grpc-gateway_out=logtostderr=true:. \
+     path/to/your_service.proto
+   ```
+   
+   It will generate a reverse proxy `path/to/your_service.pb.gw.go`.
+
+   Note: After generating the code for each of the stubs, in order to build the code, you will want to run ```go get .``` from the directory containing the stubs.
+
+6. Write an entrypoint
+   
+   Now you need to write an entrypoint of the proxy server.
+   ```go
+   package main
+
+   import (
+     "flag"
+     "net/http"
+   
+     "github.com/golang/glog"
+     "golang.org/x/net/context"
+     "github.com/grpc-ecosystem/grpc-gateway/runtime"
+     "google.golang.org/grpc"
+   	
+     gw "path/to/your_service_package"
+   )
+   
+   var (
+     echoEndpoint = flag.String("echo_endpoint", "localhost:9090", "endpoint of YourService")
+   )
+   
+   func run() error {
+     ctx := context.Background()
+     ctx, cancel := context.WithCancel(ctx)
+     defer cancel()
+   
+     mux := runtime.NewServeMux()
+     opts := []grpc.DialOption{grpc.WithInsecure()}
+     err := gw.RegisterYourServiceHandlerFromEndpoint(ctx, mux, *echoEndpoint, opts)
+     if err != nil {
+       return err
+     }
+   
+     return http.ListenAndServe(":8080", mux)
+   }
+   
+   func main() {
+     flag.Parse()
+     defer glog.Flush()
+   
+     if err := run(); err != nil {
+       glog.Fatal(err)
+     }
+   }
+   ```
+
+7. (Optional) Generate swagger definitions
+
+   ```sh
+   protoc -I/usr/local/include -I. \
+     -I$GOPATH/src \
+     -I$GOPATH/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis \
+     --swagger_out=logtostderr=true:. \
+     path/to/your_service.proto
+   ```
+
+## Parameters and flags
+`protoc-gen-grpc-gateway` supports custom mapping from Protobuf `import` to Golang import path.
+They are compatible to [the parameters with same names in `protoc-gen-go`](https://github.com/golang/protobuf#parameters).
+
+In addition we also support the `request_context` parameter in order to use the `http.Request`'s Context (only for Go 1.7 and above).
+This parameter can be useful to pass request scoped context between the gateway and the gRPC service.
+
+`protoc-gen-grpc-gateway` also supports some more command line flags to control logging. You can give these flags together with parameters above. Run `protoc-gen-grpc-gateway --help` for more details about the flags.
+
+## More Examples
+More examples are available under `examples` directory.
+* `examplepb/echo_service.proto`, `examplepb/a_bit_of_everything.proto`: service definition
+  * `examplepb/echo_service.pb.go`, `examplepb/a_bit_of_everything.pb.go`: [generated] stub of the service
+  * `examplepb/echo_service.pb.gw.go`, `examplepb/a_bit_of_everything.pb.gw.go`: [generated] reverse proxy for the service
+* `server/main.go`: service implementation
+* `main.go`: entrypoint of the generated reverse proxy
+
+To use the same port for custom HTTP handlers (e.g. serving `swagger.json`), gRPC-gateway, and a gRPC server, see [this code example by CoreOS](https://github.com/philips/grpc-gateway-example/blob/master/cmd/serve.go) (and its accompanying [blog post](https://coreos.com/blog/gRPC-protobufs-swagger.html))
+
+## Features
+### Supported
+* Generating JSON API handlers
+* Method parameters in request body
+* Method parameters in request path
+* Method parameters in query string
+* Enum fields in path parameter (including repeated enum fields).
+* Mapping streaming APIs to newline-delimited JSON streams
+* Mapping HTTP headers with `Grpc-Metadata-` prefix to gRPC metadata (prefixed with `grpcgateway-`)
+* Optionally emitting API definition for [Swagger](http://swagger.io).
+* Setting [gRPC timeouts](http://www.grpc.io/docs/guides/wire.html) through inbound HTTP `Grpc-Timeout` header.
+
+### Want to support
+But not yet.
+* bytes fields in path parameter. #5
+* Optionally generating the entrypoint. #8
+* `import_path` parameter
+
+### No plan to support
+But patch is welcome.
+* Method parameters in HTTP headers
+* Handling trailer metadata
+* Encoding request/response body in XML
+* True bi-directional streaming. (Probably impossible?)
+
+# Mapping gRPC to HTTP
+
+* [How gRPC error codes map to HTTP status codes in the response](https://github.com/grpc-ecosystem/grpc-gateway/blob/master/runtime/errors.go#L15)
+* HTTP request source IP is added as `X-Forwarded-For` gRPC request header
+* HTTP request host is added as `X-Forwarded-Host` gRPC request header
+* HTTP `Authorization` header is added as `authorization` gRPC request header 
+* Remaining Permanent HTTP header keys (as specified by the IANA [here](http://www.iana.org/assignments/message-headers/message-headers.xhtml) are prefixed with `grpcgateway-` and added with their values to gRPC request header
+* HTTP headers that start with 'Grpc-Metadata-' are mapped to gRPC metadata (prefixed with `grpcgateway-`)
+* While configurable, the default {un,}marshaling uses [jsonpb](https://godoc.org/github.com/golang/protobuf/jsonpb) with `OrigName: true`.

+
+// `HttpRule` defines the mapping of an RPC method to one or more HTTP
+// REST APIs.  The mapping determines what portions of the request
+// message are populated from the path, query parameters, or body of
+// the HTTP request.  The mapping is typically specified as an
+// `google.api.http` annotation, see "google/api/annotations.proto"
+// for details.
+//
+// The mapping consists of a field specifying the path template and
+// method kind.  The path template can refer to fields in the request
+// message, as in the example below which describes a REST GET
+// operation on a resource collection of messages:
+//
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {
+//         option (google.api.http).get = "/v1/messages/{message_id}/{sub.subfield}";
+//       }
+//     }
+//     message GetMessageRequest {
+//       message SubMessage {
+//         string subfield = 1;
+//       }
+//       string message_id = 1; // mapped to the URL
+//       SubMessage sub = 2;    // `sub.subfield` is url-mapped
+//     }
+//     message Message {
+//       string text = 1; // content of the resource
+//     }
+//
+// The same http annotation can alternatively be expressed inside the
+// `GRPC API Configuration` YAML file.
+//
+//     http:
+//       rules:
+//         - selector: <proto_package_name>.Messaging.GetMessage
+//           get: /v1/messages/{message_id}/{sub.subfield}
+//
+// This definition enables an automatic, bidrectional mapping of HTTP
+// JSON to RPC. Example:
+//
+// HTTP | RPC
+// -----|-----
+// `GET /v1/messages/123456/foo`  | `GetMessage(message_id: "123456" sub: SubMessage(subfield: "foo"))`
+//
+// In general, not only fields but also field paths can be referenced
+// from a path pattern. Fields mapped to the path pattern cannot be
+// repeated and must have a primitive (non-message) type.
+//
+// Any fields in the request message which are not bound by the path
+// pattern automatically become (optional) HTTP query
+// parameters. Assume the following definition of the request message:
+//
+//
+//     message GetMessageRequest {
+//       message SubMessage {
+//         string subfield = 1;
+//       }
+//       string message_id = 1; // mapped to the URL
+//       int64 revision = 2;    // becomes a parameter
+//       SubMessage sub = 3;    // `sub.subfield` becomes a parameter
+//     }
+//
+//
+// This enables a HTTP JSON to RPC mapping as below:
+//
+// HTTP | RPC
+// -----|-----
+// `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))`
+//
+// Note that fields which are mapped to HTTP parameters must have a
+// primitive type or a repeated primitive type. Message types are not
+// allowed. In the case of a repeated type, the parameter can be
+// repeated in the URL, as in `...?param=A&param=B`.
+//
+// For HTTP method kinds which allow a request body, the `body` field
+// specifies the mapping. Consider a REST update method on the
+// message resource collection:
+//
+//
+//     service Messaging {
+//       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//           put: "/v1/messages/{message_id}"
+//           body: "message"
+//         };
+//       }
+//     }
+//     message UpdateMessageRequest {
+//       string message_id = 1; // mapped to the URL
+//       Message message = 2;   // mapped to the body
+//     }
+//
+//
+// The following HTTP JSON to RPC mapping is enabled, where the
+// representation of the JSON in the request body is determined by
+// protos JSON encoding:
+//
+// HTTP | RPC
+// -----|-----
+// `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
+//
+// The special name `*` can be used in the body mapping to define that
+// every field not bound by the path template should be mapped to the
+// request body.  This enables the following alternative definition of
+// the update method:
+//
+//     service Messaging {
+//       rpc UpdateMessage(Message) returns (Message) {
+//         option (google.api.http) = {
+//           put: "/v1/messages/{message_id}"
+//           body: "*"
+//         };
+//       }
+//     }
+//     message Message {
+//       string message_id = 1;
+//       string text = 2;
+//     }
+//
+//
+// The following HTTP JSON to RPC mapping is enabled:
+//
+// HTTP | RPC
+// -----|-----
+// `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")`
+//
+// Note that when using `*` in the body mapping, it is not possible to
+// have HTTP parameters, as all fields not bound by the path end in
+// the body. This makes this option more rarely used in practice of
+// defining REST APIs. The common usage of `*` is in custom methods
+// which don't use the URL at all for transferring data.
+//
+// It is possible to define multiple HTTP methods for one RPC by using
+// the `additional_bindings` option. Example:
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//           get: "/v1/messages/{message_id}"
+//           additional_bindings {
+//             get: "/v1/users/{user_id}/messages/{message_id}"
+//           }
+//         };
+//       }
+//     }
+//     message GetMessageRequest {
+//       string message_id = 1;
+//       string user_id = 2;
+//     }
+//
+//
+// This enables the following two alternative HTTP JSON to RPC
+// mappings:
+//
+// HTTP | RPC
+// -----|-----
+// `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+// `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")`
+//
+// # Rules for HTTP mapping
+//
+// The rules for mapping HTTP path, query parameters, and body fields
+// to the request message are as follows:
+//
+// 1. The `body` field specifies either `*` or a field path, or is
+//    omitted. If omitted, it assumes there is no HTTP body.
+// 2. Leaf fields (recursive expansion of nested messages in the
+//    request) can be classified into three types:
+//     (a) Matched in the URL template.
+//     (b) Covered by body (if body is `*`, everything except (a) fields;
+//         else everything under the body field)
+//     (c) All other fields.
+// 3. URL query parameters found in the HTTP request are mapped to (c) fields.
+// 4. Any body sent with an HTTP request can contain only (b) fields.
+//
+// The syntax of the path template is as follows:
+//
+//     Template = "/" Segments [ Verb ] ;
+//     Segments = Segment { "/" Segment } ;
+//     Segment  = "*" | "**" | LITERAL | Variable ;
+//     Variable = "{" FieldPath [ "=" Segments ] "}" ;
+//     FieldPath = IDENT { "." IDENT } ;
+//     Verb     = ":" LITERAL ;
+//
+// The syntax `*` matches a single path segment. It follows the semantics of
+// [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+// Expansion.
+//
+// The syntax `**` matches zero or more path segments. It follows the semantics
+// of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.3 Reserved
+// Expansion. NOTE: it must be the last segment in the path except the Verb.
+//
+// The syntax `LITERAL` matches literal text in the URL path.
+//
+// The syntax `Variable` matches the entire path as specified by its template;
+// this nested template must not contain further variables. If a variable
+// matches a single path segment, its template may be omitted, e.g. `{var}`
+// is equivalent to `{var=*}`.
+//
+// NOTE: the field paths in variables and in the `body` must not refer to
+// repeated fields or map fields.
+//
+// Use CustomHttpPattern to specify any HTTP method that is not included in the
+// `pattern` field, such as HEAD, or "*" to leave the HTTP method unspecified for
+// a given URL path rule. The wild-card rule is useful for services that provide
+// content to Web (HTML) clients.
+message HttpRule {
+  // Selects methods to which this rule applies.
+  //
+  // Refer to [selector][google.api.DocumentationRule.selector] for syntax details.
+  string selector = 1;
+
+  // Determines the URL pattern is matched by this rules. This pattern can be
+  // used with any of the {get|put|post|delete|patch} methods. A custom method
+  // can be defined using the 'custom' field.

+
+    // Used for deleting a resource.
+    string delete = 5;
+
+    // Used for updating a resource.
+    string patch = 6;
+
+    // Custom pattern is used for defining custom verbs.
+    CustomHttpPattern custom = 8;
+  }
+
+  // The name of the request field whose value is mapped to the HTTP body, or

+  // body. NOTE: the referred field must not be a repeated field and must be
+  // present at the top-level of request message type.

+# Mergo
+
+A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
+
+Also a lovely [comune](http://en.wikipedia.org/wiki/Mergo) (municipality) in the Province of Ancona in the Italian region Marche.
+
+![Mergo dall'alto](http://www.comune.mergo.an.it/Siti/Mergo/Immagini/Foto/mergo_dall_alto.jpg)
+
+## Status
+
+It is ready for production use. It works fine after extensive use in the wild.

+
+### Important note
+
+Mergo is intended to assign **only** zero value fields on destination with source value. Since April 6th it works like this. Before it didn't work properly, causing some random overwrites. After some issues and PRs I found it didn't merge as I designed it. Thanks to [imdario/mergo#8](https://github.com/imdario/mergo/pull/8) overwriting functions were added and the wrong behavior was clearly detected.
+
+If you were using Mergo **before** April 6th 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause (I hope it won't!) in existing projects after the change (release 0.2.0).

+## Installation
+
+    go get github.com/imdario/mergo
+
+    // use in your .go code
+    import (
+        "github.com/imdario/mergo"
+    )
+
+## Usage
+
+You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
+
+    if err := mergo.Merge(&dst, src); err != nil {
+        // ...
+    }
+
+Additionally, you can map a map[string]interface{} to a struct (and otherwise, from struct to map), following the same restrictions as in Merge(). Keys are capitalized to find each corresponding exported field.
+
+    if err := mergo.Map(&dst, srcMap); err != nil {
+        // ...
+    }
+
+Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as map[string]interface{}. They will be just assigned as values.
+
+More information and examples in [godoc documentation](http://godoc.org/github.com/imdario/mergo).
+
+### Nice example
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/imdario/mergo"
+)
+
+type Foo struct {
+	A string
+	B int64
+}
+
+func main() {
+	src := Foo{
+		A: "one",
+	}
+
+	dest := Foo{
+		A: "two",
+		B: 2,
+	}
+
+	mergo.Merge(&dest, src)
+
+	fmt.Println(dest)
+	// Will print
+	// {two 2}
+}
+```
+
+Note: if test are failing due missing package, please execute:
+
+    go get gopkg.in/yaml.v1

+Package mergo merges same-type structs and maps by setting default values in zero-value fields.
+
+Mergo won't merge unexported (private) fields but will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
+
+Usage
+
+From my own work-in-progress project:
+
+	type networkConfig struct {
+		Protocol string
+		Address string
+		ServerType string `json: "server_type"`
+		Port uint16
+	}
+
+	type FssnConfig struct {
+		Network networkConfig
+	}
+
+	var fssnDefault = FssnConfig {
+		networkConfig {
+			"tcp",
+			"127.0.0.1",
+			"http",
+			31560,
+		},
+	}
+
+	// Inside a function [...]
+
+	if err := mergo.Merge(&config, fssnDefault); err != nil {
+		log.Fatal(err)
+	}
+
+	// More code [...]

-<h3 id="hdr-Compile_packages_and_dependencies">Compile packages and dependencies</h3>
-<p>
-Usage:
-</p>
-<pre>go build [-o output] [-i] [build flags] [packages]
-</pre>
-<p>
-Build compiles the packages named by the import paths,
-along with their dependencies, but it does not install the results.
-</p>
-<p>
-If the arguments to build are a list of .go files, build treats
-them as a list of source files specifying a single package.
-</p>
-<p>
-When compiling a single main package, build writes
-the resulting executable to an output file named after
-the first source file (&#39;go build ed.go rx.go&#39; writes &#39;ed&#39; or &#39;ed.exe&#39;)
-or the source code directory (&#39;go build unix/sam&#39; writes &#39;sam&#39; or &#39;sam.exe&#39;).
-The &#39;.exe&#39; suffix is added when writing a Windows executable.
-</p>
-<p>
-When compiling multiple packages or a single non-main package,
-build compiles the packages but discards the resulting object,
-serving only as a check that the packages can be built.
-</p>
-<p>
-When compiling packages, build ignores files that end in &#39;_test.go&#39;.
-</p>
-<p>
-The -o flag, only allowed when compiling a single package,
-forces build to write the resulting executable or object
-to the named output file, instead of the default behavior described
-in the last two paragraphs.
-</p>
-<p>
-The -i flag installs the packages that are dependencies of the target.
-</p>
-<p>
-The build flags are shared by the build, clean, get, install, list, run,
-and test commands:
-</p>
-<pre>-a
-	force rebuilding of packages that are already up-to-date.
--n
-	print the commands but do not run them.
--p n
-	the number of programs, such as build commands or
-	test binaries, that can be run in parallel.
-	The default is the number of CPUs available.
--race
-	enable data race detection.
-	Supported only on linux/amd64, freebsd/amd64, darwin/amd64 and windows/amd64.
--msan
-	enable interoperation with memory sanitizer.
-	Supported only on linux/amd64,
-	and only with Clang/LLVM as the host C compiler.
--v
-	print the names of packages as they are compiled.
--work
-	print the name of the temporary work directory and
-	do not delete it when exiting.
--x
-	print the commands.
-
--asmflags &#39;flag list&#39;
-	arguments to pass on each go tool asm invocation.
--buildmode mode
-	build mode to use. See &#39;go help buildmode&#39; for more.
--compiler name
-	name of compiler to use, as in runtime.Compiler (gccgo or gc).
--gccgoflags &#39;arg list&#39;
-	arguments to pass on each gccgo compiler/linker invocation.
--gcflags &#39;arg list&#39;
-	arguments to pass on each go tool compile invocation.
--installsuffix suffix
-	a suffix to use in the name of the package installation directory,
-	in order to keep output separate from default builds.
-	If using the -race flag, the install suffix is automatically set to race
-	or, if set explicitly, has _race appended to it.  Likewise for the -msan
-	flag.  Using a -buildmode option that requires non-default compile flags
-	has a similar effect.
--ldflags &#39;flag list&#39;
-	arguments to pass on each go tool link invocation.
--linkshared
-	link against shared libraries previously created with
-	-buildmode=shared.
--pkgdir dir
-	install and load all packages from dir instead of the usual locations.
-	For example, when building with a non-standard configuration,
-	use -pkgdir to keep generated packages in a separate location.
--tags &#39;tag list&#39;
-	a list of build tags to consider satisfied during the build.
-	For more information about build tags, see the description of
-	build constraints in the documentation for the go/build package.
--toolexec &#39;cmd args&#39;
-	a program to use to invoke toolchain programs like vet and asm.
-	For example, instead of running asm, the go command will run
-	&#39;cmd args /path/to/asm &lt;arguments for asm&gt;&#39;.
-</pre>
-<p>
-The list flags accept a space-separated list of strings. To embed spaces
-in an element in the list, surround it with either single or double quotes.
-</p>
-<p>
-For more about specifying packages, see &#39;go help packages&#39;.
-For more about where packages and binaries are installed,
-run &#39;go help gopath&#39;.
-For more about calling between Go and C/C++, run &#39;go help c&#39;.
-</p>
-<p>
-Note: Build adheres to certain conventions such as those described
-by &#39;go help gopath&#39;. Not all projects can follow these conventions,
-however. Installations that have their own conventions or that use
-a separate software build system may choose to use lower-level
-invocations such as &#39;go tool compile&#39; and &#39;go tool link&#39; to avoid
-some of the overheads and design decisions of the build tool.
-</p>

-</p>
-<h3 id="hdr-Remove_object_files">Remove object files</h3>
-<p>
-Usage:
-</p>
-<pre>go clean [-i] [-r] [-n] [-x] [build flags] [packages]
-</pre>
-<p>
-Clean removes object files from package source directories.
-The go command builds most objects in a temporary directory,
-so go clean is mainly concerned with object files left by other
-tools or by manual invocations of go build.
-</p>
-<p>
-Specifically, clean removes the following files from each of the
-source directories corresponding to the import paths:
-</p>
-<pre>_obj/            old object directory, left from Makefiles
-_test/           old test directory, left from Makefiles
-_testmain.go     old gotest file, left from Makefiles
-test.out         old test log, left from Makefiles
-build.out        old test log, left from Makefiles
-*.[568ao]        object files, left from Makefiles
-
-DIR(.exe)        from go build
-DIR.test(.exe)   from go test -c
-MAINFILE(.exe)   from go build MAINFILE.go
-*.so             from SWIG
-</pre>
-<p>
-In the list, DIR represents the final path element of the
-directory, and MAINFILE is the base name of any Go source
-file in the directory that is not included when building
-the package.
-</p>
-<p>
-The -i flag causes clean to remove the corresponding installed
-archive or binary (what &#39;go install&#39; would create).
-</p>
-<p>
-The -n flag causes clean to print the remove commands it would execute,
-but not run them.
-</p>
-<p>
-The -r flag causes clean to be applied recursively to all the
-dependencies of the packages named by the import paths.
-</p>
-<p>
-The -x flag causes clean to print remove commands as it executes them.
-</p>
-<p>
-For more about build flags, see &#39;go help build&#39;.
-</p>
-<p>
-For more about specifying packages, see &#39;go help packages&#39;.
-</p>
-<h3 id="hdr-Show_documentation_for_package_or_symbol">Show documentation for package or symbol</h3>
-<p>
-Usage:
-</p>
-<pre>go doc [-u] [-c] [package|[package.]symbol[.method]]
-</pre>
-<p>
-Doc prints the documentation comments associated with the item identified by its
-arguments (a package, const, func, type, var, or method) followed by a one-line
-summary of each of the first-level items &#34;under&#34; that item (package-level
-declarations for a package, methods for a type, etc.).
-</p>
-<p>
-Doc accepts zero, one, or two arguments.
-</p>
-<p>
-Given no arguments, that is, when run as
-</p>
-<pre>go doc
-</pre>
-<p>
-it prints the package documentation for the package in the current directory.
-If the package is a command (package main), the exported symbols of the package
-are elided from the presentation unless the -cmd flag is provided.
-</p>
-<p>
-When run with one argument, the argument is treated as a Go-syntax-like
-representation of the item to be documented. What the argument selects depends
-on what is installed in GOROOT and GOPATH, as well as the form of the argument,
-which is schematically one of these:
-</p>
-<pre>go doc &lt;pkg&gt;
-go doc &lt;sym&gt;[.&lt;method&gt;]
-go doc [&lt;pkg&gt;.]&lt;sym&gt;[.&lt;method&gt;]
-go doc [&lt;pkg&gt;.][&lt;sym&gt;.]&lt;method&gt;
-</pre>
-<p>
-The first item in this list matched by the argument is the one whose documentation
-is printed. (See the examples below.) However, if the argument starts with a capital
-letter it is assumed to identify a symbol or method in the current directory.
-</p>
-<p>
-For packages, the order of scanning is determined lexically in breadth-first order.
-That is, the package presented is the one that matches the search and is nearest
-the root and lexically first at its level of the hierarchy.  The GOROOT tree is
-always scanned in its entirety before GOPATH.
-</p>
-<p>
-If there is no package specified or matched, the package in the current
-directory is selected, so &#34;go doc Foo&#34; shows the documentation for symbol Foo in
-the current package.
-</p>
-<p>
-The package path must be either a qualified path or a proper suffix of a
-path. The go tool&#39;s usual package mechanism does not apply: package path
-elements like . and ... are not implemented by go doc.
-</p>
-<p>
-When run with two arguments, the first must be a full package path (not just a
-suffix), and the second is a symbol or symbol and method; this is similar to the
-syntax accepted by godoc:
-</p>
-<pre>go doc &lt;pkg&gt; &lt;sym&gt;[.&lt;method&gt;]
-</pre>
-<p>
-In all forms, when matching symbols, lower-case letters in the argument match
-either case but upper-case letters match exactly. This means that there may be
-multiple matches of a lower-case argument in a package if different symbols have
-different cases. If this occurs, documentation for all matches is printed.
-</p>
-<p>
-Examples:
-</p>
-<pre>go doc
-	Show documentation for current package.
-go doc Foo
-	Show documentation for Foo in the current package.
-	(Foo starts with a capital letter so it cannot match
-	a package path.)
-go doc encoding/json
-	Show documentation for the encoding/json package.
-go doc json
-	Shorthand for encoding/json.
-go doc json.Number (or go doc json.number)
-	Show documentation and method summary for json.Number.
-go doc json.Number.Int64 (or go doc json.number.int64)
-	Show documentation for json.Number&#39;s Int64 method.
-go doc cmd/doc
-	Show package docs for the doc command.
-go doc -cmd cmd/doc
-	Show package docs and exported symbols within the doc command.
-go doc template.new
-	Show documentation for html/template&#39;s New function.
-	(html/template is lexically before text/template)
-go doc text/template.new # One argument
-	Show documentation for text/template&#39;s New function.
-go doc text/template new # Two arguments
-	Show documentation for text/template&#39;s New function.
-
-At least in the current tree, these invocations all print the
-documentation for json.Decoder&#39;s Decode method:
-
-go doc json.Decoder.Decode
-go doc json.decoder.decode
-go doc json.decode
-cd go/src/encoding/json; go doc decode
-</pre>
-<p>
-Flags:
-</p>
-<pre>-c
-	Respect case when matching symbols.
--cmd
-	Treat a command (package main) like a regular package.
-	Otherwise package main&#39;s exported symbols are hidden
-	when showing the package&#39;s top-level documentation.
--u
-	Show documentation for unexported as well as exported
-	symbols and methods.
-</pre>
-<h3 id="hdr-Print_Go_environment_information">Print Go environment information</h3>
-<p>
-Usage:
-</p>
-<pre>go env [var ...]
-</pre>
-<p>
-Env prints Go environment information.

-By default env prints information as a shell script
-(on Windows, a batch file).  If one or more variable
-names is given as arguments,  env prints the value of
-each named variable on its own line.
-</p>
-<h3 id="hdr-Start_a_bug_report">Start a bug report</h3>
-<p>
-Usage:
-</p>
-<pre>go bug
-</pre>
-<p>
-Bug opens the default browser and starts a new bug report.

-<p>
-Usage:
-</p>
-<pre>go fmt [-n] [-x] [packages]
-</pre>
-<p>
-Fmt runs the command &#39;gofmt -l -w&#39; on the packages named
-by the import paths.  It prints the names of the files that are modified.
-</p>
-<p>
-For more about gofmt, see &#39;go doc cmd/gofmt&#39;.
-For more about specifying packages, see &#39;go help packages&#39;.
-</p>
-<p>
-The -n flag prints commands that would be executed.
-The -x flag prints commands as they are executed.

-<h3 id="hdr-Generate_Go_files_by_processing_source">Generate Go files by processing source</h3>
-<p>
-Usage:
-</p>
-<pre>go generate [-run regexp] [-n] [-v] [-x] [build flags] [file.go... | packages]
-</pre>
-<p>
-Generate runs commands described by directives within existing
-files. Those commands can run any process but the intent is to
-create or update Go source files.
-</p>
-<p>
-Go generate is never run automatically by go build, go get, go test,
-and so on. It must be run explicitly.
-</p>
-<p>
-Go generate scans the file for directives, which are lines of
-the form,
-</p>
-<pre>//go:generate command argument...
-</pre>
-<p>
-(note: no leading spaces and no space in &#34;//go&#34;) where command
-is the generator to be run, corresponding to an executable file
-that can be run locally. It must either be in the shell path
-(gofmt), a fully qualified path (/usr/you/bin/mytool), or a
-command alias, described below.
-</p>
-<p>
-Note that go generate does not parse the file, so lines that look
-like directives in comments or multiline strings will be treated
-as directives.
-</p>
-<p>
-The arguments to the directive are space-separated tokens or
-double-quoted strings passed to the generator as individual
-arguments when it is run.
-</p>
-<p>
-Quoted strings use Go syntax and are evaluated before execution; a
-quoted string appears as a single argument to the generator.
-</p>
-<p>
-Go generate sets several variables when it runs the generator:
-</p>
-<pre>$GOARCH
-	The execution architecture (arm, amd64, etc.)
-$GOOS
-	The execution operating system (linux, windows, etc.)
-$GOFILE
-	The base name of the file.
-$GOLINE
-	The line number of the directive in the source file.
-$GOPACKAGE
-	The name of the package of the file containing the directive.
-$DOLLAR
-	A dollar sign.
-</pre>
-<p>
-Other than variable substitution and quoted-string evaluation, no
-special processing such as &#34;globbing&#34; is performed on the command
-line.
-</p>
-<p>
-As a last step before running the command, any invocations of any
-environment variables with alphanumeric names, such as $GOFILE or
-$HOME, are expanded throughout the command line. The syntax for
-variable expansion is $NAME on all operating systems.  Due to the
-order of evaluation, variables are expanded even inside quoted
-strings. If the variable NAME is not set, $NAME expands to the
-empty string.
-</p>
-<p>
-A directive of the form,
-</p>
-<pre>//go:generate -command xxx args...
-</pre>
-<p>
-specifies, for the remainder of this source file only, that the
-string xxx represents the command identified by the arguments. This
-can be used to create aliases or to handle multiword generators.
-For example,
-</p>
-<pre>//go:generate -command foo go tool foo
-</pre>
-<p>
-specifies that the command &#34;foo&#34; represents the generator
-&#34;go tool foo&#34;.
-</p>
-<p>
-Generate processes packages in the order given on the command line,
-one at a time. If the command line lists .go files, they are treated
-as a single package. Within a package, generate processes the
-source files in a package in file name order, one at a time. Within
-a source file, generate runs generators in the order they appear
-in the file, one at a time.
-</p>
-<p>
-If any generator returns an error exit status, &#34;go generate&#34; skips
-all further processing for that package.
-</p>
-<p>
-The generator is run in the package&#39;s source directory.
-</p>
-<p>
-Go generate accepts one specific flag:
-</p>
-<pre>-run=&#34;&#34;
-	if non-empty, specifies a regular expression to select
-	directives whose full original source text (excluding
-	any trailing spaces and final newline) matches the
-	expression.
-</pre>
-<p>
-It also accepts the standard build flags including -v, -n, and -x.
-The -v flag prints the names of packages and files as they are
-processed.
-The -n flag prints commands that would be executed.
-The -x flag prints commands as they are executed.
-</p>

-<h3 id="hdr-Download_and_install_packages_and_dependencies">Download and install packages and dependencies</h3>
-<p>
-Usage:
-</p>
-<pre>go get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages]
-</pre>
-<p>
-Get downloads the packages named by the import paths, along with their
-dependencies. It then installs the named packages, like &#39;go install&#39;.
-</p>
-<p>
-The -d flag instructs get to stop after downloading the packages; that is,
-it instructs get not to install the packages.
-</p>
-<p>
-The -f flag, valid only when -u is set, forces get -u not to verify that
-each package has been checked out from the source control repository
-implied by its import path. This can be useful if the source is a local fork
-of the original.
-</p>
-<p>
-The -fix flag instructs get to run the fix tool on the downloaded packages
-before resolving dependencies or building the code.
-</p>
-<p>
-The -insecure flag permits fetching from repositories and resolving
-custom domains using insecure schemes such as HTTP. Use with caution.
-</p>
-<p>
-The -t flag instructs get to also download the packages required to build
-the tests for the specified packages.
-</p>
-<p>
-The -u flag instructs get to use the network to update the named packages
-and their dependencies.  By default, get uses the network to check out
-missing packages but does not use it to look for updates to existing packages.
-</p>
-<p>
-The -v flag enables verbose progress and debug output.
-</p>
-<p>
-Get also accepts build flags to control the installation. See &#39;go help build&#39;.
-</p>
-<p>
-When checking out a new package, get creates the target directory
-GOPATH/src/&lt;import-path&gt;. If the GOPATH contains multiple entries,
-get uses the first one. For more details see: &#39;go help gopath&#39;.
-</p>
-<p>
-When checking out or updating a package, get looks for a branch or tag
-that matches the locally installed version of Go. The most important
-rule is that if the local installation is running version &#34;go1&#34;, get
-searches for a branch or tag named &#34;go1&#34;. If no such version exists it
-retrieves the most recent version of the package.
-</p>
-<p>
-When go get checks out or updates a Git repository,
-it also updates any git submodules referenced by the repository.
-</p>
-<p>
-Get never checks out or updates code stored in vendor directories.

-<p>
-For more information about the meaning of these fields see the documentation

-</p>
-<p>
-The -json flag causes the package data to be printed in JSON format
-instead of using the template format.
-</p>
-<p>
-The -e flag changes the handling of erroneous packages, those that
-cannot be found or are malformed.  By default, the list command
-prints an error to standard error for each erroneous package and
-omits the packages from consideration during the usual printing.
-With the -e flag, the list command never prints errors to standard
-error and instead processes the erroneous packages with the usual
-printing.  Erroneous packages will have a non-empty ImportPath and
-a non-nil Error field; other information may or may not be missing
-(zeroed).

-<h3 id="hdr-Compile_and_run_Go_program">Compile and run Go program</h3>
-<p>
-Usage:
-</p>
-<pre>go run [build flags] [-exec xprog] gofiles... [arguments...]
-</pre>
-<p>
-Run compiles and runs the main package comprising the named Go source files.
-A Go source file is defined to be a file ending in a literal &#34;.go&#34; suffix.
-</p>
-<p>
-By default, &#39;go run&#39; runs the compiled binary directly: &#39;a.out arguments...&#39;.
-If the -exec flag is given, &#39;go run&#39; invokes the binary using xprog:
-</p>
-<pre>&#39;xprog a.out arguments...&#39;.
-</pre>
-<p>
-If the -exec flag is not given, GOOS or GOARCH is different from the system
-default, and a program named go_$GOOS_$GOARCH_exec can be found
-on the current search path, &#39;go run&#39; invokes the binary using that program,
-for example &#39;go_nacl_386_exec a.out arguments...&#39;. This allows execution of

-<pre>go test [build/test flags] [packages] [build/test flags &amp; test binary flags]
-</pre>
-<p>
-&#39;Go test&#39; automates testing the packages named by the import paths.
-It prints a summary of the test results in the format:
-</p>
-<pre>ok   archive/tar   0.011s
-FAIL archive/zip   0.022s
-ok   compress/gzip 0.033s
-...
-</pre>
-<p>
-followed by detailed output for each failed package.
-</p>
-<p>
-&#39;Go test&#39; recompiles each package along with any files with names matching
-the file pattern &#34;*_test.go&#34;.
-Files whose names begin with &#34;_&#34; (including &#34;_test.go&#34;) or &#34;.&#34; are ignored.
-These additional files can contain test functions, benchmark functions, and
-example functions.  See &#39;go help testfunc&#39; for more.
-Each listed package causes the execution of a separate test binary.
-</p>
-<p>
-Test files that declare a package with the suffix &#34;_test&#34; will be compiled as a
-separate package, and then linked and run with the main test binary.
-</p>
-<p>
-The go tool will ignore a directory named &#34;testdata&#34;, making it available
-to hold ancillary data needed by the tests.
-</p>
-<p>
-By default, go test needs no arguments.  It compiles and tests the package
-with source in the current directory, including tests, and runs the tests.
-</p>
-<p>
-The package is built in a temporary directory so it does not interfere with the
-non-test installation.
-</p>
-<p>
-In addition to the build flags, the flags handled by &#39;go test&#39; itself are:
-</p>
-<pre>-args
-    Pass the remainder of the command line (everything after -args)
-    to the test binary, uninterpreted and unchanged.
-    Because this flag consumes the remainder of the command line,
-    the package list (if present) must appear before this flag.
-
--c
-    Compile the test binary to pkg.test but do not run it
-    (where pkg is the last element of the package&#39;s import path).
-    The file name can be changed with the -o flag.
-
--exec xprog
-    Run the test binary using xprog. The behavior is the same as
-    in &#39;go run&#39;. See &#39;go help run&#39; for details.
-
--i
-    Install packages that are dependencies of the test.
-    Do not run the test.
-
--o file
-    Compile the test binary to the named file.
-    The test still runs (unless -c or -i is specified).
-</pre>
-<p>
-The test binary also accepts flags that control execution of the test; these
-flags are also accessible by &#39;go test&#39;. See &#39;go help testflag&#39; for details.

-The first is the cgo tool, which is part of the Go distribution.  For
-information on how to use it see the cgo documentation (go doc cmd/cgo).
-</p>
-<p>
-The second is the SWIG program, which is a general tool for
-interfacing between languages.  For information on SWIG see
-<a href="http://swig.org/">http://swig.org/</a>.  When running go build, any file with a .swig
-extension will be passed to SWIG.  Any file with a .swigcxx extension
-will be passed to SWIG with the -c++ option.
-</p>
-<p>
-When either cgo or SWIG is used, go build will pass any .c, .m, .s,
-or .S files to the C compiler, and any .cc, .cpp, .cxx files to the C++
-compiler.  The CC or CXX environment variables may be set to determine
-the C or C++ compiler, respectively, to use.
-</p>
-<h3 id="hdr-Description_of_build_modes">Description of build modes</h3>
-<p>
-The &#39;go build&#39; and &#39;go install&#39; commands take a -buildmode argument which
-indicates which kind of object file is to be built. Currently supported values
-are:
-</p>
-<pre>-buildmode=archive
-	Build the listed non-main packages into .a files. Packages named
-	main are ignored.
-
--buildmode=c-archive
-	Build the listed main package, plus all packages it imports,
-	into a C archive file. The only callable symbols will be those
-	functions exported using a cgo //export comment. Requires
-	exactly one main package to be listed.
-
--buildmode=c-shared
-	Build the listed main packages, plus all packages that they
-	import, into C shared libraries. The only callable symbols will
-	be those functions exported using a cgo //export comment.
-	Non-main packages are ignored.
-
--buildmode=default
-	Listed main packages are built into executables and listed
-	non-main packages are built into .a files (the default
-	behavior).
-
--buildmode=shared
-	Combine all the listed non-main packages into a single shared
-	library that will be used when building with the -linkshared
-	option. Packages named main are ignored.
-
--buildmode=exe
-	Build the listed main packages and everything they import into
-	executables. Packages not named main are ignored.
-
--buildmode=pie
-	Build the listed main packages and everything they import into
-	position independent executables (PIE). Packages not named
-	main are ignored.
-
--buildmode=plugin
-	Build the listed main packages, plus all packages that they
-	import, into a Go plugin. Packages not named main are ignored.
-</pre>
-<h3 id="hdr-File_types">File types</h3>
-<p>
-The go command examines the contents of a restricted set of files
-in each directory. It identifies which files to examine based on
-the extension of the file name. These extensions are:
-</p>
-<pre>.go
-	Go source files.
-.c, .h
-	C source files.
-	If the package uses cgo or SWIG, these will be compiled with the
-	OS-native compiler (typically gcc); otherwise they will
-	trigger an error.
-.cc, .cpp, .cxx, .hh, .hpp, .hxx
-	C++ source files. Only useful with cgo or SWIG, and always
-	compiled with the OS-native compiler.
-.m
-	Objective-C source files. Only useful with cgo, and always
-	compiled with the OS-native compiler.
-.s, .S
-	Assembler source files.
-	If the package uses cgo or SWIG, these will be assembled with the
-	OS-native assembler (typically gcc (sic)); otherwise they
-	will be assembled with the Go assembler.
-.swig, .swigcxx
-	SWIG definition files.
-.syso
-	System object files.
-</pre>
-<p>
-Files of each of these types except .syso may contain build
-constraints, but the go command stops scanning for build constraints
-at the first item in the file that is not a blank line or //-style
-line comment. See the go/build package documentation for
-more details.
-</p>
-<p>
-Non-test Go source files can also include a //go:binary-only-package
-comment, indicating that the package sources are included
-for documentation only and must not be used to build the
-package binary. This enables distribution of Go packages in
-their compiled form alone. See the go/build package documentation
-for more details.

-It is implemented by and documented in the go/build package.
-</p>
-<p>
-The GOPATH environment variable lists places to look for Go code.
-On Unix, the value is a colon-separated string.
-On Windows, the value is a semicolon-separated string.
-On Plan 9, the value is a list.
-</p>
-<p>
-If the environment variable is unset, GOPATH defaults
-to a subdirectory named &#34;go&#34; in the user&#39;s home directory
-($HOME/go on Unix, %USERPROFILE%\go on Windows),
-unless that directory holds a Go distribution.
-Run &#34;go env GOPATH&#34; to see the current GOPATH.
-</p>
-<p>
-See <a href="https://golang.org/wiki/SettingGOPATH">https://golang.org/wiki/SettingGOPATH</a> to set a custom GOPATH.
-</p>
-<p>
-Each directory listed in GOPATH must have a prescribed structure:
-</p>
-<p>
-The src directory holds source code.  The path below src
-determines the import path or executable name.
-</p>
-<p>
-The pkg directory holds installed package objects.
-As in the Go tree, each target operating system and
-architecture pair has its own subdirectory of pkg
-(pkg/GOOS_GOARCH).
-</p>
-<p>
-If DIR is a directory listed in the GOPATH, a package with
-source in DIR/src/foo/bar can be imported as &#34;foo/bar&#34; and
-has its compiled form installed to &#34;DIR/pkg/GOOS_GOARCH/foo/bar.a&#34;.
-</p>
-<p>
-The bin directory holds compiled commands.
-Each command is named for its source directory, but only
-the final element, not the entire path.  That is, the
-command with source in DIR/src/foo/quux is installed into
-DIR/bin/quux, not DIR/bin/foo/quux.  The &#34;foo/&#34; prefix is stripped
-so that you can add DIR/bin to your PATH to get at the
-installed commands.  If the GOBIN environment variable is
-set, commands are installed to the directory it names instead
-of DIR/bin. GOBIN must be an absolute path.
-</p>
-<p>
-Here&#39;s an example directory layout:
-</p>
-<pre>GOPATH=/home/user/go
-
-/home/user/go/
-    src/
-        foo/
-            bar/               (go code in package bar)
-                x.go
-            quux/              (go code in package main)
-                y.go
-    bin/
-        quux                   (installed command)
-    pkg/
-        linux_amd64/
-            foo/
-                bar.a          (installed package object)
-</pre>
-<p>
-Go searches each directory listed in GOPATH to find source code,
-but new packages are always downloaded into the first directory
-in the list.
-</p>
-<p>
-See <a href="https://golang.org/doc/code.html">https://golang.org/doc/code.html</a> for an example.
-</p>
-<h3 id="hdr-Internal_Directories">Internal Directories</h3>
-<p>
-Code in or below a directory named &#34;internal&#34; is importable only
-by code in the directory tree rooted at the parent of &#34;internal&#34;.
-Here&#39;s an extended version of the directory layout above:
-</p>
-<pre>/home/user/go/
-    src/
-        crash/
-            bang/              (go code in package bang)
-                b.go
-        foo/                   (go code in package foo)
-            f.go
-            bar/               (go code in package bar)
-                x.go
-            internal/
-                baz/           (go code in package baz)
-                    z.go
-            quux/              (go code in package main)
-                y.go
-</pre>
-<p>
-The code in z.go is imported as &#34;foo/internal/baz&#34;, but that
-import statement can only appear in source files in the subtree
-rooted at foo. The source files foo/f.go, foo/bar/x.go, and
-foo/quux/y.go can all import &#34;foo/internal/baz&#34;, but the source file
-crash/bang/b.go cannot.
-</p>
-<p>
-See <a href="https://golang.org/s/go14internal">https://golang.org/s/go14internal</a> for details.
-</p>
-<h3 id="hdr-Vendor_Directories">Vendor Directories</h3>
-<p>
-Go 1.6 includes support for using local copies of external dependencies
-to satisfy imports of those dependencies, often referred to as vendoring.
-</p>
-<p>
-Code below a directory named &#34;vendor&#34; is importable only
-by code in the directory tree rooted at the parent of &#34;vendor&#34;,
-and only using an import path that omits the prefix up to and
-including the vendor element.
-</p>
-<p>
-Here&#39;s the example from the previous section,
-but with the &#34;internal&#34; directory renamed to &#34;vendor&#34;
-and a new foo/vendor/crash/bang directory added:
-</p>
-<pre>/home/user/go/
-    src/
-        crash/
-            bang/              (go code in package bang)
-                b.go
-        foo/                   (go code in package foo)
-            f.go
-            bar/               (go code in package bar)
-                x.go
-            vendor/
-                crash/
-                    bang/      (go code in package bang)
-                        b.go
-                baz/           (go code in package baz)
-                    z.go
-            quux/              (go code in package main)
-                y.go
-</pre>
-<p>
-The same visibility rules apply as for internal, but the code
-in z.go is imported as &#34;baz&#34;, not as &#34;foo/vendor/baz&#34;.
-</p>
-<p>
-Code in vendor directories deeper in the source tree shadows
-code in higher directories. Within the subtree rooted at foo, an import
-of &#34;crash/bang&#34; resolves to &#34;foo/vendor/crash/bang&#34;, not the
-top-level &#34;crash/bang&#34;.
-</p>
-<p>
-Code in vendor directories is not subject to import path
-checking (see &#39;go help importpath&#39;).
-</p>
-<p>
-When &#39;go get&#39; checks out or updates a git repository, it now also
-updates submodules.
-</p>
-<p>
-Vendor directories do not affect the placement of new repositories
-being checked out for the first time by &#39;go get&#39;: those are always
-placed in the main GOPATH, never in a vendor subtree.
-</p>

-See <a href="https://golang.org/s/go15vendor">https://golang.org/s/go15vendor</a> for details.

-</pre>
-<h3 id="hdr-Import_path_syntax">Import path syntax</h3>
-<p>
-An import path (see &#39;go help packages&#39;) denotes a package stored in the local
-file system.  In general, an import path denotes either a standard package (such
-as &#34;unicode/utf8&#34;) or a package found in one of the work spaces (For more
-details see: &#39;go help gopath&#39;).
-</p>
-<h3 id="hdr-Relative_import_paths">Relative import paths</h3>
-<p>
-An import path beginning with ./ or ../ is called a relative path.
-The toolchain supports relative import paths as a shortcut in two ways.
-</p>
-<p>
-First, a relative path can be used as a shorthand on the command line.
-If you are working in the directory containing the code imported as
-&#34;unicode&#34; and want to run the tests for &#34;unicode/utf8&#34;, you can type
-&#34;go test ./utf8&#34; instead of needing to specify the full path.
-Similarly, in the reverse situation, &#34;go test ..&#34; will test &#34;unicode&#34; from
-the &#34;unicode/utf8&#34; directory. Relative patterns are also allowed, like
-&#34;go test ./...&#34; to test all subdirectories. See &#39;go help packages&#39; for details
-on the pattern syntax.
-</p>
-<p>
-Second, if you are compiling a Go program not in a work space,
-you can use a relative path in an import statement in that program
-to refer to nearby code also not in a work space.
-This makes it easy to experiment with small multipackage programs
-outside of the usual work spaces, but such programs cannot be
-installed with &#34;go install&#34; (there is no work space in which to install them),
-so they are rebuilt from scratch each time they are built.
-To avoid ambiguity, Go programs cannot use relative import paths
-within a work space.
-</p>
-<h3 id="hdr-Remote_import_paths">Remote import paths</h3>
-<p>
-Certain import paths also
-describe how to obtain the source code for the package using
-a revision control system.
-</p>
-<p>
-A few common code hosting sites have special syntax:
-</p>
-<pre>Bitbucket (Git, Mercurial)
-
-	import &#34;bitbucket.org/user/project&#34;
-	import &#34;bitbucket.org/user/project/sub/directory&#34;
-
-GitHub (Git)
-
-	import &#34;github.com/user/project&#34;
-	import &#34;github.com/user/project/sub/directory&#34;
-
-Launchpad (Bazaar)
-
-	import &#34;launchpad.net/project&#34;
-	import &#34;launchpad.net/project/series&#34;
-	import &#34;launchpad.net/project/series/sub/directory&#34;
-
-	import &#34;launchpad.net/~user/project/branch&#34;
-	import &#34;launchpad.net/~user/project/branch/sub/directory&#34;
-
-IBM DevOps Services (Git)
-
-	import &#34;hub.jazz.net/git/user/project&#34;
-	import &#34;hub.jazz.net/git/user/project/sub/directory&#34;
-</pre>
-<p>
-For code hosted on other servers, import paths may either be qualified
-with the version control type, or the go tool can dynamically fetch
-the import path over https/http and discover where the code resides
-from a &lt;meta&gt; tag in the HTML.
-</p>
-<p>
-To declare the code location, an import path of the form
-</p>
-<pre>repository.vcs/path
-</pre>
-<p>
-specifies the given repository, with or without the .vcs suffix,
-using the named version control system, and then the path inside
-that repository.  The supported version control systems are:
-</p>
-<pre>Bazaar      .bzr
-Git         .git
-Mercurial   .hg
-Subversion  .svn
-</pre>
-<p>
-For example,
-</p>
-<pre>import &#34;example.org/user/foo.hg&#34;
-</pre>
-<p>
-denotes the root directory of the Mercurial repository at
-example.org/user/foo or foo.hg, and
-</p>
-<pre>import &#34;example.org/repo.git/foo/bar&#34;
-</pre>
-<p>
-denotes the foo/bar directory of the Git repository at
-example.org/repo or repo.git.
-</p>
-<p>
-When a version control system supports multiple protocols,
-each is tried in turn when downloading.  For example, a Git
-download tries https://, then git+ssh://.
-</p>
-<p>
-By default, downloads are restricted to known secure protocols
-(e.g. https, ssh). To override this setting for Git downloads, the
-GIT_ALLOW_PROTOCOL environment variable can be set (For more details see:
-&#39;go help environment&#39;).
-</p>
-<p>
-If the import path is not a known code hosting site and also lacks a
-version control qualifier, the go tool attempts to fetch the import
-over https/http and looks for a &lt;meta&gt; tag in the document&#39;s HTML
-&lt;head&gt;.
-</p>
-<p>
-The meta tag has the form:
-</p>
-<pre>&lt;meta name=&#34;go-import&#34; content=&#34;import-prefix vcs repo-root&#34;&gt;
-</pre>
-<p>
-The import-prefix is the import path corresponding to the repository
-root. It must be a prefix or an exact match of the package being
-fetched with &#34;go get&#34;. If it&#39;s not an exact match, another http
-request is made at the prefix to verify the &lt;meta&gt; tags match.
-</p>
-<p>
-The meta tag should appear as early in the file as possible.
-In particular, it should appear before any raw JavaScript or CSS,
-to avoid confusing the go command&#39;s restricted parser.
-</p>
-<p>
-The vcs is one of &#34;git&#34;, &#34;hg&#34;, &#34;svn&#34;, etc,
-</p>
-<p>
-The repo-root is the root of the version control system
-containing a scheme and not containing a .vcs qualifier.
-</p>
-<p>
-For example,
-</p>
-<pre>import &#34;example.org/pkg/foo&#34;
-</pre>
-<p>
-will result in the following requests:
-</p>
-<pre><a href="https://example.org/pkg/foo?go-get=1">https://example.org/pkg/foo?go-get=1</a> (preferred)
-<a href="http://example.org/pkg/foo?go-get=1">http://example.org/pkg/foo?go-get=1</a>  (fallback, only with -insecure)
-</pre>
-<p>
-If that page contains the meta tag
-</p>
-<pre>&lt;meta name=&#34;go-import&#34; content=&#34;example.org git <a href="https://code.org/r/p/exproj">https://code.org/r/p/exproj</a>&#34;&gt;
-</pre>
-<p>
-the go tool will verify that <a href="https://example.org/?go-get=1">https://example.org/?go-get=1</a> contains the
-same meta tag and then git clone <a href="https://code.org/r/p/exproj">https://code.org/r/p/exproj</a> into
-GOPATH/src/example.org.
-</p>
-<p>
-New downloaded packages are written to the first directory listed in the GOPATH
-environment variable (For more details see: &#39;go help gopath&#39;).
-</p>
-<p>
-The go command attempts to download the version of the
-package appropriate for the Go release being used.
-Run &#39;go help get&#39; for more.
-</p>
-<h3 id="hdr-Import_path_checking">Import path checking</h3>
-<p>
-When the custom import path feature described above redirects to a
-known code hosting site, each of the resulting packages has two possible
-import paths, using the custom domain or the known hosting site.
-</p>
-<p>
-A package statement is said to have an &#34;import comment&#34; if it is immediately
-followed (before the next newline) by a comment of one of these two forms:
-</p>
-<pre>package math // import &#34;path&#34;
-package math /* import &#34;path&#34; */
-</pre>
-<p>
-The go command will refuse to install a package with an import comment
-unless it is being referred to by that import path. In this way, import comments
-let package authors make sure the custom import path is used and not a
-direct path to the underlying code hosting site.
-</p>
-<p>
-Import path checking is disabled for code found within vendor trees.
-This makes it possible to copy code into alternate locations in vendor trees
-without needing to update import comments.
-</p>
-<p>
-See <a href="https://golang.org/s/go14customimport">https://golang.org/s/go14customimport</a> for details.
-</p>
-<h3 id="hdr-Description_of_package_lists">Description of package lists</h3>
-<p>
-Many commands apply to a set of packages:
-</p>
-<pre>go action [packages]
-</pre>
-<p>
-Usually, [packages] is a list of import paths.
-</p>
-<p>
-An import path that is a rooted path or that begins with
-a . or .. element is interpreted as a file system path and
-denotes the package in that directory.
-</p>
-<p>
-Otherwise, the import path P denotes the package found in
-the directory DIR/src/P for some DIR listed in the GOPATH
-environment variable (For more details see: &#39;go help gopath&#39;).
-</p>
-<p>
-If no import paths are given, the action applies to the
-package in the current directory.
-</p>
-<p>
-There are four reserved names for paths that should not be used
-for packages to be built with the go tool:
-</p>
-<p>
-- &#34;main&#34; denotes the top-level package in a stand-alone executable.
-</p>
-<p>
-- &#34;all&#34; expands to all package directories found in all the GOPATH
-trees. For example, &#39;go list all&#39; lists all the packages on the local
-system.
-</p>
-<p>
-- &#34;std&#34; is like all but expands to just the packages in the standard
-Go library.
-</p>
-<p>
-- &#34;cmd&#34; expands to the Go repository&#39;s commands and their
-internal libraries.
-</p>
-<p>
-Import paths beginning with &#34;cmd/&#34; only match source code in
-the Go repository.
-</p>
-<p>
-An import path is a pattern if it includes one or more &#34;...&#34; wildcards,
-each of which can match any string, including the empty string and
-strings containing slashes.  Such a pattern expands to all package
-directories found in the GOPATH trees with names matching the
-patterns.  As a special case, x/... matches x as well as x&#39;s subdirectories.
-For example, net/... expands to net and packages in its subdirectories.
-</p>
-<p>
-An import path can also name a package to be downloaded from
-a remote repository.  Run &#39;go help importpath&#39; for details.
-</p>
-<p>
-Every package in a program must have a unique import path.
-By convention, this is arranged by starting each path with a
-unique prefix that belongs to you.  For example, paths used
-internally at Google all begin with &#39;google&#39;, and paths
-denoting remote repositories begin with the path to the code,
-such as &#39;github.com/user/repo&#39;.
-</p>
-<p>
-Packages in a program need not have unique package names,
-but there are two reserved package names with special meaning.
-The name main indicates a command, not a library.
-Commands are built into binaries and cannot be imported.
-The name documentation indicates documentation for
-a non-Go program in the directory. Files in package documentation
-are ignored by the go command.
-</p>
-<p>
-As a special case, if the package list is a list of .go files from a
-single directory, the command is applied to a single synthesized
-package made up of exactly those files, ignoring any build constraints
-in those files and ignoring any other files in the directory.
-</p>
-<p>
-Directory and file names that begin with &#34;.&#34; or &#34;_&#34; are ignored
-by the go tool, as are directories named &#34;testdata&#34;.
-</p>
-<h3 id="hdr-Description_of_testing_flags">Description of testing flags</h3>
-<p>
-The &#39;go test&#39; command takes both flags that apply to &#39;go test&#39; itself
-and flags that apply to the resulting test binary.
-</p>
-<p>
-Several of the flags control profiling and write an execution profile
-suitable for &#34;go tool pprof&#34;; run &#34;go tool pprof -h&#34; for more
-information.  The --alloc_space, --alloc_objects, and --show_bytes
-options of pprof control how the information is presented.
-</p>
-<p>
-The following flags are recognized by the &#39;go test&#39; command and
-control the execution of any test:
-</p>
-<pre>-bench regexp
-    Run (sub)benchmarks matching a regular expression.
-    The given regular expression is split into smaller ones by
-    top-level &#39;/&#39;, where each must match the corresponding part of a
-    benchmark&#39;s identifier.
-    By default, no benchmarks run. To run all benchmarks,
-    use &#39;-bench .&#39; or &#39;-bench=.&#39;.
-
--benchtime t
-    Run enough iterations of each benchmark to take t, specified
-    as a time.Duration (for example, -benchtime 1h30s).
-    The default is 1 second (1s).
-
--count n
-    Run each test and benchmark n times (default 1).
-    If -cpu is set, run n times for each GOMAXPROCS value.
-    Examples are always run once.
-
--cover
-    Enable coverage analysis.
-
--covermode set,count,atomic
-    Set the mode for coverage analysis for the package[s]
-    being tested. The default is &#34;set&#34; unless -race is enabled,
-    in which case it is &#34;atomic&#34;.
-    The values:
-	set: bool: does this statement run?
-	count: int: how many times does this statement run?
-	atomic: int: count, but correct in multithreaded tests;
-		significantly more expensive.
-    Sets -cover.
-
--coverpkg pkg1,pkg2,pkg3
-    Apply coverage analysis in each test to the given list of packages.
-    The default is for each test to analyze only the package being tested.
-    Packages are specified as import paths.
-    Sets -cover.
-
--cpu 1,2,4
-    Specify a list of GOMAXPROCS values for which the tests or
-    benchmarks should be executed.  The default is the current value
-    of GOMAXPROCS.
-
--parallel n
-    Allow parallel execution of test functions that call t.Parallel.
-    The value of this flag is the maximum number of tests to run
-    simultaneously; by default, it is set to the value of GOMAXPROCS.
-    Note that -parallel only applies within a single test binary.
-    The &#39;go test&#39; command may run tests for different packages
-    in parallel as well, according to the setting of the -p flag
-    (see &#39;go help build&#39;).
-
--run regexp
-    Run only those tests and examples matching the regular expression.
-    For tests the regular expression is split into smaller ones by
-    top-level &#39;/&#39;, where each must match the corresponding part of a
-    test&#39;s identifier.
-
--short
-    Tell long-running tests to shorten their run time.
-    It is off by default but set during all.bash so that installing
-    the Go tree can run a sanity check but not spend time running
-    exhaustive tests.
-
--timeout t
-    If a test runs longer than t, panic.
-    The default is 10 minutes (10m).
-
--v
-    Verbose output: log all tests as they are run. Also print all
-    text from Log and Logf calls even if the test succeeds.
-</pre>
-<p>
-The following flags are also recognized by &#39;go test&#39; and can be used to
-profile the tests during execution:
-</p>
-<pre>-benchmem
-    Print memory allocation statistics for benchmarks.
-
--blockprofile block.out
-    Write a goroutine blocking profile to the specified file
-    when all tests are complete.
-    Writes test binary as -c would.
-
--blockprofilerate n
-    Control the detail provided in goroutine blocking profiles by
-    calling runtime.SetBlockProfileRate with n.
-    See &#39;go doc runtime.SetBlockProfileRate&#39;.
-    The profiler aims to sample, on average, one blocking event every
-    n nanoseconds the program spends blocked.  By default,
-    if -test.blockprofile is set without this flag, all blocking events
-    are recorded, equivalent to -test.blockprofilerate=1.
-
--coverprofile cover.out
-    Write a coverage profile to the file after all tests have passed.
-    Sets -cover.
-
--cpuprofile cpu.out
-    Write a CPU profile to the specified file before exiting.
-    Writes test binary as -c would.
-
--memprofile mem.out
-    Write a memory profile to the file after all tests have passed.
-    Writes test binary as -c would.
-
--memprofilerate n
-    Enable more precise (and expensive) memory profiles by setting
-    runtime.MemProfileRate.  See &#39;go doc runtime.MemProfileRate&#39;.
-    To profile all memory allocations, use -test.memprofilerate=1
-    and pass --alloc_space flag to the pprof tool.
-
--mutexprofile mutex.out
-    Write a mutex contention profile to the specified file
-    when all tests are complete.
-    Writes test binary as -c would.
-
--mutexprofilefraction n
-    Sample 1 in n stack traces of goroutines holding a
-    contended mutex.
-
--outputdir directory
-    Place output files from profiling in the specified directory,
-    by default the directory in which &#34;go test&#34; is running.
-
--trace trace.out
-    Write an execution trace to the specified file before exiting.
-</pre>
-<p>
-Each of these flags is also recognized with an optional &#39;test.&#39; prefix,
-as in -test.v. When invoking the generated test binary (the result of
-&#39;go test -c&#39;) directly, however, the prefix is mandatory.
-</p>
-<p>
-The &#39;go test&#39; command rewrites or removes recognized flags,
-as appropriate, both before and after the optional package list,
-before invoking the test binary.
-</p>
-<p>
-For instance, the command
-</p>
-<pre>go test -v -myflag testdata -cpuprofile=prof.out -x
-</pre>
-<p>
-will compile the test binary and then run it as
-</p>
-<pre>pkg.test -test.v -myflag testdata -test.cpuprofile=prof.out
-</pre>
-<p>
-(The -x flag is removed because it applies only to the go command&#39;s
-execution, not to the test itself.)
-</p>
-<p>
-The test flags that generate profiles (other than for coverage) also
-leave the test binary in pkg.test for use when analyzing the profiles.
-</p>
-<p>
-When &#39;go test&#39; runs a test binary, it does so from within the
-corresponding package&#39;s source code directory. Depending on the test,
-it may be necessary to do the same when invoking a generated test
-binary directly.
-</p>
-<p>
-The command-line package list, if present, must appear before any
-flag not known to the go test command. Continuing the example above,
-the package list would have to appear before -myflag, but could appear
-on either side of -v.
-</p>
-<p>
-To keep an argument for a test binary from being interpreted as a
-known flag or a package name, use -args (see &#39;go help test&#39;) which
-passes the remainder of the command line through to the test binary
-uninterpreted and unaltered.
-</p>
-<p>
-For instance, the command
-</p>
-<pre>go test -v -args -x -v
-</pre>
-<p>
-will compile the test binary and then run it as
-</p>
-<pre>pkg.test -test.v -x -v
-</pre>
-<p>
-Similarly,
-</p>
-<pre>go test -args math
-</pre>
-<p>
-will compile the test binary and then run it as
-</p>
-<pre>pkg.test math
-</pre>
-<p>
-In the first example, the -x and the second -v are passed through to the
-test binary unchanged and with no effect on the go command itself.
-In the second example, the argument math is passed through to the test
-binary, instead of being interpreted as the package list.
-</p>
-<h3 id="hdr-Description_of_testing_functions">Description of testing functions</h3>
-<p>
-The &#39;go test&#39; command expects to find test, benchmark, and example functions
-in the &#34;*_test.go&#34; files corresponding to the package under test.
-</p>
-<p>
-A test function is one named TestXXX (where XXX is any alphanumeric string
-not starting with a lower case letter) and should have the signature,
-</p>
-<pre>func TestXXX(t *testing.T) { ... }
-</pre>
-<p>
-A benchmark function is one named BenchmarkXXX and should have the signature,
-</p>
-<pre>func BenchmarkXXX(b *testing.B) { ... }
-</pre>
-<p>
-An example function is similar to a test function but, instead of using
-*testing.T to report success or failure, prints output to os.Stdout.
-If the last comment in the function starts with &#34;Output:&#34; then the output
-is compared exactly against the comment (see examples below). If the last
-comment begins with &#34;Unordered output:&#34; then the output is compared to the
-comment, however the order of the lines is ignored. An example with no such
-comment is compiled but not executed. An example with no text after
-&#34;Output:&#34; is compiled, executed, and expected to produce no output.
-</p>
-<p>
-Godoc displays the body of ExampleXXX to demonstrate the use
-of the function, constant, or variable XXX.  An example of a method M with
-receiver type T or *T is named ExampleT_M.  There may be multiple examples
-for a given function, constant, or variable, distinguished by a trailing _xxx,
-where xxx is a suffix not beginning with an upper case letter.
-</p>
-<p>
-Here is an example of an example:
-</p>
-<pre>func ExamplePrintln() {
-	Println(&#34;The output of\nthis example.&#34;)
-	// Output: The output of
-	// this example.
-}
-</pre>
-<p>
-Here is another example where the ordering of the output is ignored:
-</p>
-<pre>func ExamplePerm() {
-	for _, value := range Perm(4) {
-		fmt.Println(value)
-	}
-
-	// Unordered output: 4
-	// 2
-	// 1
-	// 3
-	// 0
-}
-</pre>
-<p>
-The entire test file is presented as the example when it contains a single
-example function, at least one other function, type, variable, or constant
-declaration, and no test or benchmark functions.
-</p>
-<p>
-See the documentation of the testing package for more information.

+	//
+	// Currently supported tiers from low to high:
+	// VERY_LOW, LOW, STANDARD, HIGH, VERY_HIGH
+	//
+	// To apply different limit values for users according to their tiers, specify
+	// the values for the tiers you want to differentiate. For example:
+	// {LOW:100, STANDARD:500, HIGH:1000, VERY_HIGH:5000}
+	//
+	// The limit value for each tier is optional except for the tier STANDARD.
+	// The limit value for an unspecified tier falls to the value of its next
+	// tier towards tier STANDARD. For the above example, the limit value for tier
+	// STANDARD is 500.
+	//
+	// To apply the same limit value for all users, just specify limit value for
+	// tier STANDARD. For example: {STANDARD:500}.
+	//
+	// To apply a regional overide for a tier, add a map entry with key
+	// "<TIER>/<region>", where <region> is a region name. Similarly, for a zone
+	// override, add a map entry with key "<TIER>/{zone}".
+	// Further, a wildcard can be used at the end of a zone name in order to
+	// specify zone level overrides. For example:
+	// LOW: 10, STANDARD: 50, HIGH: 100,
+	// LOW/us-central1: 20, STANDARD/us-central1: 60, HIGH/us-central1: 200,
+	// LOW/us-central1-*: 10, STANDARD/us-central1-*: 20, HIGH/us-central1-*: 80
+	//
+	// The regional overrides tier set for each region must be the same as
+	// the tier set for default limit values. Same rule applies for zone overrides
+	// tier as well.

+	//    Note that some namespaces and entities will not support recursive
+	//    watching. When watching such an entity, a client must not set recursive
+	//    to true. Otherwise, it will receive an `UNIMPLEMENTED` error.
+	//
+	// Normal URL encoding must be used inside `target`.  For example, if a query
+	// parameter name or value, or the non-query parameter portion of `target`

-# Mocking Service for gRPC
-
-[Example code](https://github.com/grpc/grpc-go/tree/master/examples/helloworld/mock)
-
-## Why?
-
-To test client-side logic without the overhead of connecting to a real server. Mocking enables users to write light-weight unit tests to check functionalities on client-side without invoking RPC calls to a server. 
-
-## Idea: Mock the client stub that connects to the server.
-
-We use Gomock to mock the client interface (in the generated code) and programmatically set its methods to expect and return pre-determined values. This enables users to write tests around the client logic and use this mocked stub while making RPC calls.
-
-## How to use Gomock?
-
-Documentation on Gomock can be found [here](https://github.com/golang/mock).
-A quick reading of the documentation should enable users to follow the code below.
-
-Consider a gRPC service based on following proto file:
-
-```proto
-//helloworld.proto
-
-package helloworld;
-
-message HelloRequest {
-    string name = 1;
-}
-
-message HelloReply {
-    string name = 1;
-}
-
-service Greeter {
-    rpc SayHello (HelloRequest) returns (HelloReply) {}
-}
-```
-
-The generated file helloworld.pb.go will have a client interface for each service defined in the proto file. This interface will have methods corresponding to each rpc inside that service.
-
-```Go
-type GreeterClient interface {
-    SayHello(ctx context.Context, in *HelloRequest, opts ...grpc.CallOption) (*HelloReply, error)
-}
-```
-
-The generated code also contains a struct that implements this interface.
-
-```Go
-type greeterClient struct {
-   cc *grpc.ClientConn
-}
-func (c *greeterClient) SayHello(ctx context.Context, in *HelloRequest, opts ...grpc.CallOption) (*HelloReply, error){
-    // ...
-    // gRPC specific code here
-    // ...
-}
-```
-
-Along with this the generated code has a method to create an instance of this struct.
-```Go
-func NewGreeterClient(cc *grpc.ClientConn) GreeterClient
-```
-
-The user code uses this function to create an instance of the struct greeterClient which then can be used to make rpc calls to the server. 
-We will mock this interface GreeterClient and use an instance of that mock to make rpc calls. These calls instead of going to server will return pre-determined values.
-
-To create a mock we’ll use [mockgen](https://github.com/golang/mock#running-mockgen).
-From the directory ``` examples/helloworld/mock/ ``` run ``` mockgen google.golang.org/grpc/examples/helloworld/helloworld GreeterClient > mock_helloworld/hw_mock.go ```
-
-Notice that in the above command we specify GreeterClient as the interface to be mocked.
-
-The user test code can import the package generated by mockgen along with library package gomock to write unit tests around client-side logic.
-```Go
-import "github.com/golang/mock/gomock"
-import hwmock "google.golang.org/grpc/examples/helloworld/mock/mock_helloworld"
-```
-
-An instance of the mocked interface can be created as:
-```Go
-mockGreeterClient := hwmock.NewMockGreeterClient(ctrl)
-```
-This mocked object can be programmed to expect calls to its methods and return pre-determined values. For instance, we can program mockGreeterClient to expect a call to its method SayHello and return a HelloReply with message “Mocked RPC”.
-
-```Go
-mockGreeterClient.EXPECT().SayHello(
-    gomock.Any(), // expect any value for first parameter
-    gomock.Any(), // expect any value for second parameter
-).Return(&helloworld.HelloReply{Message: “Mocked RPC”}, nil) 
-```
-
-gomock.Any() indicates that the parameter can have any value or type. We can indicate specific values for built-in types with gomock.Eq().
-However, if the test code needs to specify the parameter to have a proto message type, we can replace gomock.Any() with an instance of a struct that implements gomock.Matcher interface.
-
-```Go
-type rpcMsg struct {
-    msg proto.Message
-}
-
-func (r *rpcMsg) Matches(msg interface{}) bool {
-    m, ok := msg.(proto.Message)
-    if !ok {
-        return false
-    }
-    return proto.Equal(m, r.msg)
-}
-
-func (r *rpcMsg) String() string {
-    return fmt.Sprintf("is %s", r.msg)
-}
-
-...
-
-req := &helloworld.HelloRequest{Name: "unit_test"}
-mockGreeterClient.EXPECT().SayHello(
-    gomock.Any(),
-    &rpcMsg{msg: req},
-).Return(&helloworld.HelloReply{Message: "Mocked Interface"}, nil)

-# gRPC Server Reflection Tutorial
-
-gRPC Server Reflection provides information about publicly-accessible gRPC
-services on a server, and assists clients at runtime to construct RPC
-requests and responses without precompiled service information. It is used by
-gRPC CLI, which can be used to introspect server protos and send/receive test
-RPCs.
-
-## Enable Server Reflection
-
-gRPC-go Server Reflection is implemented in package [reflection](https://github.com/grpc/grpc-go/tree/master/reflection). To enable server reflection, you need to import this package and register reflection service on your gRPC server.
-
-For example, to enable server reflection in `example/helloworld`, we need to make the following changes:
-
-```diff

-                log.Fatalf("failed to serve: %v", err)
-        }
-```
-
-We have made this change in `example/helloworld`, and we will use it as an example to show the use of gRPC server reflection and gRPC CLI in this tutorial.
-
-## gRPC CLI
-
-After enabling Server Reflection in a server application, you can use gRPC CLI to check its services.
-gRPC CLI is only available in c++. Instructions on how to use gRPC CLI can be found at [command_line_tool.md](https://github.com/grpc/grpc/blob/master/doc/command_line_tool.md).
-
-To build gRPC CLI:
-
-```sh
-git clone https://github.com/grpc/grpc
-cd grpc
-make grpc_cli
-cd bins/opt # grpc_cli is in directory bins/opt/
-```
-
-## Use gRPC CLI to check services
-
-First, start the helloworld server in grpc-go directory:
-
-```sh
-$ cd <grpc-go-directory>
-$ go run examples/helloworld/greeter_server/main.go
-```
-
-Open a new terminal and make sure you are in the directory where grpc_cli lives:
-
-```sh
-$ cd <grpc-cpp-dirctory>/bins/opt
-```
-
-### List services
-
-`grpc_cli ls` command lists services and methods exposed at a given port:
-
-- List all the services exposed at a given port
-
-  ```sh
-  $ ./grpc_cli ls localhost:50051
-  ```
-
-  output:
-  ```sh
-  helloworld.Greeter
-  grpc.reflection.v1alpha.ServerReflection
-  ```
-
-- List one service with details
-
-  `grpc_cli ls` command inspects a service given its full name (in the format of
-  \<package\>.\<service\>). It can print information with a long listing format
-  when `-l` flag is set. This flag can be used to get more details about a
-  service.
-
-  ```sh
-  $ ./grpc_cli ls localhost:50051 helloworld.Greeter -l
-  ```
-
-  output:
-  ```sh
-  filename: helloworld.proto
-  package: helloworld;
-  service Greeter {
-    rpc SayHello(helloworld.HelloRequest) returns (helloworld.HelloReply) {}
-  }
-
-  ```
-
-### List methods
-
-- List one method with details
-
-  `grpc_cli ls` command also inspects a method given its full name (in the
-  format of \<package\>.\<service\>.\<method\>).
-
-  ```sh
-  $ ./grpc_cli ls localhost:50051 helloworld.Greeter.SayHello -l
-  ```
-
-  output:
-  ```sh
-    rpc SayHello(helloworld.HelloRequest) returns (helloworld.HelloReply) {}
-  ```
-
-### Inspect message types
-
-We can use`grpc_cli type` command to inspect request/response types given the
-full name of the type (in the format of \<package\>.\<type\>).
-
-- Get information about the request type
-
-  ```sh
-  $ ./grpc_cli type localhost:50051 helloworld.HelloRequest
-  ```
-
-  output:
-  ```sh
-  message HelloRequest {
-    optional string name = 1[json_name = "name"];
-  }
-  ```
-
-### Call a remote method
-
-We can send RPCs to a server and get responses using `grpc_cli call` command.
-
-- Call a unary method
-
-  ```sh
-  $ ./grpc_cli call localhost:50051 SayHello "name: 'gRPC CLI'"
-  ```
-
-  output:
-  ```sh
-  message: "Hello gRPC CLI"
-  ```

-
-From https://golang.org/doc/install, one way to install the latest version of go is:
-```

 -----------
 The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the [list](http://godoc.org/google.golang.org/grpc?imports), you need a discussion with gRPC-Go authors and consultants.

 ## Defining the service
 
-Our first step (as you'll know from the [quick start](http://www.grpc.io/docs/#quick-start)) is to define the gRPC *service* and the method *request* and *response* types using [protocol buffers](https://developers.google.com/protocol-buffers/docs/overview). You can see the complete .proto file in [examples/route_guide/routeguide/route_guide.proto](https://github.com/grpc/grpc-go/tree/master/examples/route_guide/routeguide/route_guide.proto).
