Re: [go-nuts] protoc question

[Tharaneedharan Vilwanathan]

Hi Josh,

Got it! I had it all working but I was a bit confused when I noticed only
Go related help text was missing in help text. Thanks for the
quick response and clarification!

Regards
dharani

Re: [go-nuts] protoc question

[Josh Humphries]

Support for Go is not built into protoc. Instead, Go code gen relies on a
protoc plugin. A serious omission from the help output for protoc is how to
use plugins:

--_out  Generate source code by invoking plugin program named
protoc-gen-.

So, to use the --go_out flag, you need to install the Go plugin, which is
named protoc-gen-go
. To install
that plugin, you can use the Go tool:

go get github.com/golang/protobuf/protoc-gen-go

When protoc tries to invoke protoc-gen-go, it will expect to find it in
your PATH environment. But you can also use a --plugin flag to protoc to
tell it exactly where the plugin binary lives.

[go-nuts] protoc question

[Tharaneedharan Vilwanathan]

Hi All,

I have a minor question. When I run "protoc --help", I do not see "go_out"
option but I see others:

  --cpp_out=OUT_DIR   Generate C++ header and source.
  --csharp_out=OUT_DIRGenerate C# source file.
  --java_out=OUT_DIR  Generate Java source file.
  --js_out=OUT_DIRGenerate JavaScript source.
  --objc_out=OUT_DIR  Generate Objective C header and source.
  --php_out=OUT_DIR   Generate PHP source file.
  --python_out=OUT_DIRGenerate Python source file.
  --ruby_out=OUT_DIR  Generate Ruby source file.

Is it a minor bug or am I missing something?

Thanks
dharani
