gRPC Ruby

A Ruby implementation of gRPC.

PREREQUISITES

• Ruby 2.x. The gRPC API uses keyword args.

INSTALLATION

Linux and Mac OS X:

gem install grpc

BUILD FROM SOURCE

• Clone this repository

• Init submodules

git submodule update --init

• Install Ruby 2.x. Consider doing this with RVM, it's a nice way of controlling the exact ruby version that's used.

$ command curl -sSL https://rvm.io/mpapis.asc | gpg --import -
$ \curl -sSL https://get.rvm.io | bash -s stable --ruby=ruby-2
$
$ # follow the instructions to ensure that your're using the latest stable version of Ruby
$ # and that the rvm command is installed

• Make sure your run source $HOME/.rvm/scripts/rvm as instructed to complete the set up of RVM

• Install bundler

$ gem install bundler

• Finally, build and install the gRPC gem locally.

$ # from this directory
$ bundle install # creates the ruby bundle, including building the grpc extension
$ rake # runs the unit tests, see rake -T for other options

DOCUMENTATION

• rubydoc for the gRPC gem is available online at rubydoc.
• the gRPC Ruby reference documentation is available online at grpc.io

CONTENTS

Directory structure is the layout for ruby extensions

• ext: the gRPC ruby extension

• lib: the entrypoint gRPC ruby library to be used in a 'require' statement

• spec: Rspec unittests

• bin: example gRPC clients and servers, e.g,

  stub=Math::Math::Stub.new('my.test.math.server.com:8080',:this_channel_is_insecure)req=Math::DivArgs.new(dividend: 7,divisor: 3)GRPC.logger.info("div(7/3): req=#{req.inspect}")resp=stub.div(req)GRPC.logger.info("Answer: #{resp.inspect}")
