// protoc-gen-go is a plugin for the Google protocol buffer compiler to generate
|
||
|
|
// Go code. Install it by building this program and making it accessible within
|
||
|
|
// your PATH with the name:
|
||
|
|
// protoc-gen-go
|
||
|
|
//
|
||
|
|
// The 'go' suffix becomes part of the argument for the protocol compiler,
|
||
|
|
// such that it can be invoked as:
|
||
|
|
// protoc --go_out=paths=source_relative:. path/to/file.proto
|
||
|
|
//
|
||
|
|
// This generates Go bindings for the protocol buffer defined by file.proto.
|
||
|
|
// With that input, the output will be written to:
|
||
|
|
// path/to/file.pb.go
|
||
