Development

Setup

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

GRPC Client

Protobuf definitions are stored in the dapr/proto directory of this repo.

There is a script, bin/regen_client.sh, that can be used to regenerate the Ruby client from the protocol definitions. The generated code can be found in lib/dapr/proto and is added to the lib path.
