It works in concert with the Go source code generated -for .proto files by the protocol compiler. - -A summary of the properties of the protocol buffer interface -for a protocol buffer variable v: - - - Names are turned from camel_case to CamelCase for export. - - There are no methods on v to set fields; just treat - them as structure fields. - - There are getters that return a field's value if set, - and return the field's default value if unset. - The getters work even if the receiver is a nil message. - - The zero value for a struct is its correct initialization state. - All desired fields must be set before marshaling. - - A Reset() method will restore a protobuf struct to its zero state. - - Non-repeated fields are pointers to the values; nil means unset. - That is, optional or required field int32 f becomes F *int32. - - Repeated fields are slices. - - Helper functions are available to aid the setting of fields. - msg.Foo = proto.String("hello") // set field - - Constants are defined to hold the default values of all fields that - have them. They have the form Default_StructName_FieldName. - Because the getter methods handle defaulted values, - direct use of these constants should be rare. - - Enums are given type names and maps from names to values. - Enum values are prefixed by the enclosing message's name, or by the - enum's type name if it is a top-level enum. Enum types have a String - method, and a Enum method to assist in message construction. - - Nested messages, groups and enums have type names prefixed with the name of - the surrounding message type. - - Extensions are given descriptor names that start with E_, - followed by an underscore-delimited list of the nested messages - that contain it (if any) followed by the CamelCased name of the - extension field itself. HasExtension, ClearExtension, GetExtension - and SetExtension are functions for manipulating extensions. - - Oneof field sets are given a single field in their message, - with distinguished wrapper types for each possible field value. - - Marshal and Unmarshal are functions to encode and decode the wire format. - -When the .proto file specifies `syntax="proto3"`, there are some differences: - - - Non-repeated fields of non-message type are values instead of pointers. - - Enum types do not get an Enum method. - -The simplest way to describe this is to see an example. -Given file test.proto, containing - - package example;

It will take a JSON +document and transform it into another JSON document +through a JMESPath expression. + +Using go-jmespath is really easy. There's a single function +you use, `jmespath.search`: + + +```go +> import "github.com/jmespath/go-jmespath" +> +> var jsondata = []byte(`{"foo": {"bar": {"baz": [0, 1, 2, 3, 4]}}}`) // your data +> var data interface{} +> err := json.Unmarshal(jsondata, &data) +> result, err := jmespath.Search("foo.bar.baz[2]", data) +result = 2 +``` + +In the example we gave the ``search`` function input data of +`{"foo": {"bar": {"baz": [0, 1, 2, 3, 4]}}}` as well as the JMESPath +expression `foo.bar.baz[2]`, and the `search` function evaluated +the expression against the input data to produce the result ``2``. + +The JMESPath language can do a lot more than select an element +from a list. Here are a few more examples: + +```go +> var jsondata = []byte(`{"foo": {"bar": {"baz": [0, 1, 2, 3, 4]}}}`) // your data +> var data interface{} +> err := json.Unmarshal(jsondata, &data) +> result, err := jmespath.search("foo.bar", data) +result = { "baz": [ 0, 1, 2, 3, 4 ] } + + +> var jsondata = []byte(`{"foo": [{"first": "a", "last": "b"}, + {"first": "c", "last": "d"}]}`) // your data +> var data interface{} +> err := json.Unmarshal(jsondata, &data) +> result, err := jmespath.search({"foo[*].first", data) +result [ 'a', 'c' ] + + +> var jsondata = []byte(`{"foo": [{"age": 20}, {"age": 25}, + {"age": 30}, {"age": 35}, + {"age": 40}]}`) // your data +> var data interface{} +> err := json.Unmarshal(jsondata, &data) +> result, err := jmespath.search("foo[?age > `30`]") +result = [ { age: 35 }, { age: 40 } ] +``` + +You can also pre-compile your query. This is usefull if +you are going to run multiple searches with it: + +```go + > var jsondata = []byte(`{"foo": "bar"}`) + > var data interface{} + > err := json.Unmarshal(jsondata, &data) + > precompiled, err := Compile("foo") + > if err != nil{ + > // ... handle the error + > } + > result, err := precompiled.Search(data) + result = "bar" +``` + +## More Resources + +The example above only show a small amount of what +a JMESPath expression can do.

AMQP is programmable, meaning that both the producers and -consumers agree on the configuration of the broker, instead requiring an +consumers agree on the configuration of the broker, instead of requiring an operator or system configuration that declares the logical topology in the broker. The routing between producers and consumer queues is via Bindings. These bindings form the logical topology of the broker. diff --git a/vendor/github.com/streadway/amqp/go.mod b/vendor/github.com/streadway/amqp/go.mod new file mode 100644 index 00000000..4eeab334 --- /dev/null +++ b/vendor/github.com/streadway/amqp/go.mod @@ -0,0 +1,3 @@ +module github.com/streadway/amqp + +go 1.10 diff --git a/vendor/github.com/streadway/amqp/pre-commit b/vendor/github.com/streadway/amqp/pre-commit index 7607f467..37155300 100644 --- a/vendor/github.com/streadway/amqp/pre-commit +++ b/vendor/github.com/streadway/amqp/pre-commit @@ -1,29 +1,67 @@ #!/bin/sh -GOFMT_FILES=$(gofmt -l .) -if [ -n "${GOFMT_FILES}" ]; then -

That is, the +// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z" +// where {year} is always expressed using four digits while {month}, {day}, +// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional +// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution), +// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone +// is required. A proto3 JSON serializer should always use UTC (as indicated by +// "Z") when printing the Timestamp type and a proto3 JSON parser should be +// able to accept both UTC and other timezones (as indicated by an offset). +// +// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past +// 01:30 UTC on January 15, 2017. +// +// In JavaScript, one can convert a Date object to this format using the +// standard +// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString) +// method. In Python, a standard `datetime.datetime` object can be converted +// to this format using +// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with +// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use +// the Joda Time's [`ISODateTimeFormat.dateTime()`]( +// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D +// ) to obtain a formatter capable of generating timestamps in this format. +// +// +type Timestamp struct { + state protoimpl.MessageState + sizeCache protoimpl.SizeCache + unknownFields protoimpl.UnknownFields + + // Represents seconds of UTC time since Unix epoch + // 1970-01-01T00:00:00Z.
