From 91473dcebfbd90a8e256568e287e168b70c77ff0 Mon Sep 17 00:00:00 2001 From: Chris Fallin Date: Fri, 12 Dec 2014 15:58:26 -0800 Subject: Rename protobuf Ruby module to google/protobuf and rework its build system. The Ruby module build now uses an amalgamated distribution of upb, and successfully builds a Ruby gem called 'google-protobuf' with module 'google/protobuf'. --- ruby/ext/google/protobuf_c/upb.h | 7439 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 7439 insertions(+) create mode 100644 ruby/ext/google/protobuf_c/upb.h (limited to 'ruby/ext/google/protobuf_c/upb.h') diff --git a/ruby/ext/google/protobuf_c/upb.h b/ruby/ext/google/protobuf_c/upb.h new file mode 100644 index 00000000..150aef10 --- /dev/null +++ b/ruby/ext/google/protobuf_c/upb.h @@ -0,0 +1,7439 @@ +// Amalgamated source file +/* + * upb - a minimalist implementation of protocol buffers. + * + * Copyright (c) 2009-2012 Google Inc.
