This repository contains the SDK for Cobalt's Juzu Speech Diarization Engine.

The grpc folder at the top level of this repository contains code for Juzu's GRPC API. The grpc/juzu.proto file is the authoritative service definition of the API and is used for auto generating SDK code in multiple languages.

The grpc folder contains auto-generated code in several languages. In order to generate the code again, you should run make. Generated code is checked in, and you must make sure it is up to date when you push commits to this repository.

Code generation has the following dependencies:

• The protobuf compiler itself (protoc)
• The protobuf documentation generation plugin (protoc-gen-doc)
• The golang plugins (protoc-gen-go and protoc-gen-grpc-gateway)

A few system dependencies are required:

• Go 1.12
• git
• wget

The top level Makefile can set up all other dependencies.

To generate the code and documentation, run make.

This repository has several components, and they need more than just a "vX.Y.Z" tag on the git repo. In particular, this repository has two go modules, one of which depends on the other, and in order to make sure correct versions are used, we need to follow a few careful steps to release new versions on this repository.

Step 1: Make sure all generated code and documentation is up to date.

pushd grpc && make && popd

Step 2: Update the version number.

In addition to the git tags, we also save the version string in a few places in our sources. These strings should all be updated and a new commit created. The git tags should then be placed on that commit once merged to master.

Decide which version you'd like to tag. For this README, let's say the next version to tag is 1.0.1.

Step 3: Add version tags to the sources.

NEW_VERSION="1.0.1"

git checkout master
git checkout -b version-update-v$NEW_VERSION

sed -i 's|grpc/go-juzu v[0-9.]*|grpc/go-juzu v'$NEW_VERSION'|g' grpc/go-juzu/juzupb/gw/go.mod
sed -i 's|<Version>[0-9.]*</Version>|<Version>'$NEW_VERSION'</Version>|g' grpc/csharp-juzu/juzu.csproj
sed -i 's|^VERSION="[0-9.]*"|VERSION="'$NEW_VERSION'"|g' grpc/Makefile

git commit -m "Update version to v$NEW_VERSION"
git push origin version-update-v$NEW_VERSION

Step 4: Create a pull request and get changes merged to master.

Step 5: Create version tags on the latest master branch:

git checkout master
git pull origin master
git tag -a v$NEW_VERSION -m ''
git tag -a grpc/go-juzu/v$NEW_VERSION -m ''
git tag -a grpc/go-juzu/juzupb/gw/v$NEW_VERSION -m ''
git push origin --tags
