For +information about protocol buffers themselves, see + https://developers.google.com/protocol-buffers/ + +## Installation ## + +To use this software, you must: +- Install the standard C++ implementation of protocol buffers from + https://developers.google.com/protocol-buffers/ +- Of course, install the Go compiler and tools from + https://golang.org/ + See + https://golang.org/doc/install + for details or, if you are using gccgo, follow the instructions at + https://golang.org/doc/install/gccgo +- Grab the code from the repository and install the proto package. + The simplest way is to run `go get -u github.com/golang/protobuf/protoc-gen-go`. + The compiler plugin, protoc-gen-go, will be installed in $GOBIN, + defaulting to $GOPATH/bin. It must be in your $PATH for the protocol + compiler, protoc, to find it. + +This software has two parts: a 'protocol compiler plugin' that +generates Go source files that, once compiled, can access and manage +protocol buffers; and a library that implements run-time support for +encoding (marshaling), decoding (unmarshaling), and accessing protocol +buffers. + +There is support for gRPC in Go using protocol buffers. +See the note at the bottom of this file for details. + +There are no insertion points in the plugin. + + +## Using protocol buffers with Go ## + +Once the software is installed, there are two steps to using it. +First you must compile the protocol buffer definitions and then import +them, with the support library, into your program. + +To compile the protocol buffer definition, run protoc with the --go_out +parameter set to the directory you want to output the Go code to. + + protoc --go_out=. *.proto + +The generated files will be suffixed .pb.go. See the Test code below +for an example using such a file. + + +The package comment for the proto library contains text describing +the interface provided in Go for protocol buffers. Here is an edited +version. + +========== + +The proto package converts data structures to and from the +wire format of protocol buffers. 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. + Helpers for getting values are superseded by the + GetFoo methods and their use is deprecated. + 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 with the enum's type name. Enum types have + a String method, and a Enum method to assist in message construction. + - Nested 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. + +Consider file test.proto, containing + +```proto + syntax = "proto2"; + package example; + + enum FOO { X = 17; }; + + message Test { + required string label = 1; + optional int32 type = 2 [default=77]; + repeated int64 reps = 3; + optional group OptionalGroup = 4 { + required string RequiredField = 5; + } + } +``` + +To create and play with a Test object from the example package, + +```go + package main + + import ( + "log" + + "github.com/golang/protobuf/proto" + "path/to/example" + ) + + func main() { + test := &example.Test { + Label: proto.String("hello"), + Type: proto.Int32(17), + Reps: []int64{1, 2, 3}, + Optionalgroup: &example.Test_OptionalGroup { + RequiredField: proto.String("good bye"), + }, + } + data, err := proto.Marshal(test) + if err != nil { + log.Fatal("marshaling error: ", err) + } + newTest := &example.Test{} + err = proto.Unmarshal(data, newTest) + if err != nil { + log.Fatal("unmarshaling error: ", err) + } + // Now test and newTest contain the same data. + if test.GetLabel() != newTest.GetLabel() { + log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel()) + } + // etc. + } +``` + +## Parameters ## + +To pass extra parameters to the plugin, use a comma-separated +parameter list separated from the output directory by a colon: + + + protoc --go_out=plugins=grpc,import_path=mypackage:. *.proto + + +- `import_prefix=xxx` - a prefix that is added onto the beginning of + all imports. Useful for things like generating protos in a + subdirectory, or regenerating vendored protobufs in-place. +- `import_path=foo/bar` - used as the package if no input files + declare `go_package`. If it contains slashes, everything up to the + rightmost slash is ignored. +- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to + load. The only plugin in this repo is `grpc`. +- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is + associated with Go package quux/shme. This is subject to the + import_prefix parameter. + +## gRPC Support ## + +If a proto file specifies RPC services, protoc-gen-go can be instructed to +generate code compatible with gRPC (http://www.grpc.io/). To do this, pass +the `plugins` parameter to protoc-gen-go; the usual way is to insert it into +the --go_out argument to protoc: + + protoc --go_out=plugins=grpc:. *.proto + +## Compatibility ## + +The library and the generated code are expected to be stable over time. +However, we reserve the right to make breaking changes without notice for the +following reasons: + +- Security. A security issue in the specification or implementation may come to + light whose resolution requires breaking compatibility. We reserve the right + to address such security issues. +- Unspecified behavior. There are some aspects of the Protocol Buffers + specification that are undefined. Programs that depend on such unspecified + behavior may break in future releases. +- Specification errors or changes. If it becomes necessary to address an + inconsistency, incompleteness, or change in the Protocol Buffers + specification, resolving the issue could affect the meaning or legality of + existing programs. We reserve the right to address such issues, including + updating the implementations. +- Bugs. If the library has a bug that violates the specification, a program + that depends on the buggy behavior may break if the bug is fixed. We reserve + the right to fix such bugs. +- Adding methods or fields to generated structs. These may conflict with field + names that already exist in a schema, causing applications to break. When the + code generator encounters a field in the schema that would collide with a + generated field or method name, the code generator will append an underscore + to the generated field or method name. +- Adding, removing, or changing methods or fields in generated structs that + start with `XXX`. These parts of the generated code are exported out of + necessity, but should not be considered part of the public API. +- Adding, removing, or changing unexported symbols in generated code. + +Any breaking changes outside of these will be announced 6 months in advance to +protobuf@googlegroups.com. + +You should, whenever possible, use generated code created by the `protoc-gen-go` +tool built at the same commit as the `proto` package. The `proto` package +declares package-level constants in the form `ProtoPackageIsVersionX`. +Application code and generated code may depend on one of these constants to +ensure that compilation will fail if the available version of the proto library +is too old. Whenever we make a change to the generated code that requires newer +library support, in the same commit we will increment the version number of the +generated code and declare a new package-level constant whose name incorporates +the latest version number. Removing a compatibility constant is considered a +breaking change and would be subject to the announcement policy stated above. + +The `protoc-gen-go/generator` package exposes a plugin interface, +which is used by the gRPC code generation. This interface is not +supported and is subject to incompatible changes without notice. diff --git a/tools/grammars/vendor/github.com/golang/protobuf/proto/Makefile b/tools/grammars/vendor/github.com/golang/protobuf/proto/Makefile new file mode 100644 index 0000000000..e2e0651a93 --- /dev/null +++ b/tools/grammars/vendor/github.com/golang/protobuf/proto/Makefile @@ -0,0 +1,43 @@ +# Go support for Protocol Buffers - Google's data interchange format +# +# Copyright 2010 The Go Authors.

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;

This is great, but the problem is if +you have configuration or an encoding that changes slightly depending on +specific fields. For example, consider this JSON: + +```json +{ + "type": "person", + "name": "Mitchell" +} +``` + +Perhaps we can't populate a specific structure without first reading +the "type" field from the JSON. We could always do two passes over the +decoding of the JSON (reading the "type" first, and the rest later). +However, it is much simpler to just decode this into a `map[string]interface{}` +structure, read the "type" key, then use something like this library +to decode it into the proper structure. diff --git a/tools/grammars/vendor/github.com/mitchellh/mapstructure/decode_hooks.go b/tools/grammars/vendor/github.com/mitchellh/mapstructure/decode_hooks.go new file mode 100644 index 0000000000..afcfd5eed6 --- /dev/null +++ b/tools/grammars/vendor/github.com/mitchellh/mapstructure/decode_hooks.go @@ -0,0 +1,152 @@ +package mapstructure + +import ( + "errors" + "reflect" + "strconv" + "strings" + "time" +) + +// typedDecodeHook takes a raw DecodeHookFunc (an interface{}) and turns +// it into the proper DecodeHookFunc type, such as DecodeHookFuncType. +func typedDecodeHook(h DecodeHookFunc) DecodeHookFunc { + // Create variables here so we can reference them with the reflect pkg + var f1 DecodeHookFuncType + var f2 DecodeHookFuncKind + + // Fill in the variables into this interface and the rest is done + // automatically using the reflect package. + potential := []interface{}{f1, f2} + + v := reflect.ValueOf(h) + vt := v.Type() + for _, raw := range potential { + pt := reflect.ValueOf(raw).Type() + if vt.ConvertibleTo(pt) { + return v.Convert(pt).Interface() + } + } + + return nil +} + +// DecodeHookExec executes the given decode hook.

It was developed within [Canonical](https://www.canonical.com) as +part of the [juju](https://juju.ubuntu.com) project, and is based on a +pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML) +C library to parse and generate YAML data quickly and reliably. + +Compatibility +------------- + +The yaml package supports most of YAML 1.1 and 1.2, including support for +anchors, tags, map merging, etc. Multi-document unmarshalling is not yet +implemented, and base-60 floats from YAML 1.1 are purposefully not +supported since they're a poor design and are gone in YAML 1.2. + +Installation and usage +---------------------- + +The import path for the package is *gopkg.in/yaml.v2*. + +To install it, run: + + go get gopkg.in/yaml.v2 + +API documentation +----------------- + +If opened in a browser, the import path itself leads to the API documentation: + + * [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2) + +API stability +------------- + +The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in). + + +License +------- + +The yaml package is licensed under the Apache License 2.0.

For -information about protocol buffers themselves, see - https://developers.google.com/protocol-buffers/ - -## Installation ## - -To use this software, you must: -- Install the standard C++ implementation of protocol buffers from - https://developers.google.com/protocol-buffers/ -- Of course, install the Go compiler and tools from - https://golang.org/ - See - https://golang.org/doc/install - for details or, if you are using gccgo, follow the instructions at - https://golang.org/doc/install/gccgo -- Grab the code from the repository and install the proto package. - The simplest way is to run `go get -u github.com/golang/protobuf/protoc-gen-go`. - The compiler plugin, protoc-gen-go, will be installed in $GOBIN, - defaulting to $GOPATH/bin. It must be in your $PATH for the protocol - compiler, protoc, to find it. - -This software has two parts: a 'protocol compiler plugin' that -generates Go source files that, once compiled, can access and manage -protocol buffers; and a library that implements run-time support for -encoding (marshaling), decoding (unmarshaling), and accessing protocol -buffers. - -There is support for gRPC in Go using protocol buffers. -See the note at the bottom of this file for details. - -There are no insertion points in the plugin. - - -## Using protocol buffers with Go ## - -Once the software is installed, there are two steps to using it. -First you must compile the protocol buffer definitions and then import -them, with the support library, into your program. - -To compile the protocol buffer definition, run protoc with the --go_out -parameter set to the directory you want to output the Go code to. - - protoc --go_out=. *.proto - -The generated files will be suffixed .pb.go. See the Test code below -for an example using such a file. - - -The package comment for the proto library contains text describing -the interface provided in Go for protocol buffers. Here is an edited -version. - -========== - -The proto package converts data structures to and from the -wire format of protocol buffers. 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. - Helpers for getting values are superseded by the - GetFoo methods and their use is deprecated. - 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 with the enum's type name. Enum types have - a String method, and a Enum method to assist in message construction. - - Nested 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. - -Consider file test.proto, containing - -```proto - syntax = "proto2"; - package example; - - enum FOO { X = 17; }; - - message Test { - required string label = 1; - optional int32 type = 2 [default=77]; - repeated int64 reps = 3; - optional group OptionalGroup = 4 { - required string RequiredField = 5; - } - } -``` - -To create and play with a Test object from the example package, - -```go - package main - - import ( - "log" - - "github.com/golang/protobuf/proto" - "path/to/example" - ) - - func main() { - test := &example.Test { - Label: proto.String("hello"), - Type: proto.Int32(17), - Reps: []int64{1, 2, 3}, - Optionalgroup: &example.Test_OptionalGroup { - RequiredField: proto.String("good bye"), - }, - } - data, err := proto.Marshal(test) - if err != nil { - log.Fatal("marshaling error: ", err) - } - newTest := &example.Test{} - err = proto.Unmarshal(data, newTest) - if err != nil { - log.Fatal("unmarshaling error: ", err) - } - // Now test and newTest contain the same data. - if test.GetLabel() != newTest.GetLabel() { - log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel()) - } - // etc. - } -``` - -## Parameters ## - -To pass extra parameters to the plugin, use a comma-separated -parameter list separated from the output directory by a colon: - - - protoc --go_out=plugins=grpc,import_path=mypackage:. *.proto - - -- `import_prefix=xxx` - a prefix that is added onto the beginning of - all imports. Useful for things like generating protos in a - subdirectory, or regenerating vendored protobufs in-place. -- `import_path=foo/bar` - used as the package if no input files - declare `go_package`. If it contains slashes, everything up to the - rightmost slash is ignored. -- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to - load. The only plugin in this repo is `grpc`. -- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is - associated with Go package quux/shme. This is subject to the - import_prefix parameter. - -## gRPC Support ## - -If a proto file specifies RPC services, protoc-gen-go can be instructed to -generate code compatible with gRPC (http://www.grpc.io/). To do this, pass -the `plugins` parameter to protoc-gen-go; the usual way is to insert it into -the --go_out argument to protoc: - - protoc --go_out=plugins=grpc:. *.proto - -## Compatibility ## - -The library and the generated code are expected to be stable over time. -However, we reserve the right to make breaking changes without notice for the -following reasons: - -- Security. A security issue in the specification or implementation may come to - light whose resolution requires breaking compatibility. We reserve the right - to address such security issues. -- Unspecified behavior. There are some aspects of the Protocol Buffers - specification that are undefined. Programs that depend on such unspecified - behavior may break in future releases. -- Specification errors or changes. If it becomes necessary to address an - inconsistency, incompleteness, or change in the Protocol Buffers - specification, resolving the issue could affect the meaning or legality of - existing programs. We reserve the right to address such issues, including - updating the implementations. -- Bugs. If the library has a bug that violates the specification, a program - that depends on the buggy behavior may break if the bug is fixed. We reserve - the right to fix such bugs. -- Adding methods or fields to generated structs. These may conflict with field - names that already exist in a schema, causing applications to break. When the - code generator encounters a field in the schema that would collide with a - generated field or method name, the code generator will append an underscore - to the generated field or method name. -- Adding, removing, or changing methods or fields in generated structs that - start with `XXX`. These parts of the generated code are exported out of - necessity, but should not be considered part of the public API. -- Adding, removing, or changing unexported symbols in generated code. - -Any breaking changes outside of these will be announced 6 months in advance to -protobuf@googlegroups.com. - -You should, whenever possible, use generated code created by the `protoc-gen-go` -tool built at the same commit as the `proto` package. The `proto` package -declares package-level constants in the form `ProtoPackageIsVersionX`. -Application code and generated code may depend on one of these constants to -ensure that compilation will fail if the available version of the proto library -is too old. Whenever we make a change to the generated code that requires newer -library support, in the same commit we will increment the version number of the -generated code and declare a new package-level constant whose name incorporates -the latest version number. Removing a compatibility constant is considered a -breaking change and would be subject to the announcement policy stated above. - -The `protoc-gen-go/generator` package exposes a plugin interface, -which is used by the gRPC code generation. This interface is not -supported and is subject to incompatible changes without notice. diff --git a/tools/grammars/vendor/github.com/golang/protobuf/proto/Makefile b/tools/grammars/vendor/github.com/golang/protobuf/proto/Makefile deleted file mode 100644 index e2e0651a93..0000000000 --- a/tools/grammars/vendor/github.com/golang/protobuf/proto/Makefile +++ /dev/null @@ -1,43 +0,0 @@ -# Go support for Protocol Buffers - Google's data interchange format -# -# Copyright 2010 The Go Authors.
