gRPC in 3 minutes (Ruby)
========================

PREREQUISITES
-------------

This requires Ruby 2.1, as the gRPC API surface uses keyword args.

If you don't have that installed locally, you can use [RVM](https://www.rvm.io/) to use Ruby 2.1 for testing without upgrading the version of Ruby on your whole system.
```sh
$ command curl -sSL https://rvm.io/mpapis.asc | gpg --import -
$ \curl -sSL https://get.rvm.io | bash -s stable --ruby=ruby-2.1
$
$ # 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
-------

- Clone this repository.
- Follow the instructions in [INSTALL](https://github.com/grpc/grpc/blob/master/INSTALL) to install the gRPC C core.
- *Temporary* Install the full gRPC distribution from source on your local machine and update path: in [Gemfile](https://github.com/grpc/grpc-common/blob/master/ruby/Gemfile) to refer src/ruby within it.
  - this is necessary until the gRPC ruby gem is published
