th2_grpc_generator_template

th2 gRPC generator template library (1.4.0)

This is the template project for creating custom gRPC libraries. It contains an example of proto messages and services.
The tool generates code from .proto files and uploads built packages (.proto files and generated code) to the specified repositories.

How to transform the template

1. Create a directory with the same name as the project name (use underscores instead of dashes) under src/main/proto directory (remove other files and directories if they exist).
2. Place your custom .proto files in the created directory. Pay attention to both the package specifier and to the import statements.
3. Edit release_version and vcs_url properties in gradle.properties file.
4. Edit rootProject.name variable in settings.gradle file. This will be the name of the Java package.
5. Edit package_info.json file in order to specify its name and its version for Python package (create the file in case it's absent).
6. Edit parameters of setup.py in setup function invocation such as: author, author_email, url. Do not edit the other's parameters.
7. Edit README.md file according to the new project.

Note that the name of the created directory under src/main/proto directory is used in Python (it's a package name).

How to maintain a project

1. Perform the necessary changes.
2. Update the package version of Java in gradle.properties file.
3. Update the package version of Python in package_info.json file.
4. Commit everything.

How to run project

Java

If you wish to manually create and publish a package for Java, run the following command:

gradle --no-daemon clean build publish artifactoryPublish \
       -Purl=${URL} \ 
       -Puser=${USER} \
       -Ppassword=${PASSWORD}

URL, USER and PASSWORD are parameters for publishing.

Python

If you wish to manually create and publish a package for Python:

1. Generate services with Gradle:

      gradle --no-daemon clean generateProto
   

   You can find the generated files by following path: src/gen/main/services/python
2. Generate code from .proto files and publish everything using twine:

   pip install -r requirements.txt
   pip install twine
   python setup.py generate
   python setup.py sdist
   twine upload --repository-url ${PYPI_REPOSITORY_URL} --username ${PYPI_USER} --password ${PYPI_PASSWORD} dist/*
   

   PYPI_REPOSITORY_URL, PYPI_USER and PYPI_PASSWORD are parameters for publishing.
