replit-river 0.12.0

Replit river toolkit for Python

River

Machinery for compatibility with https://github.com/replit/river, the protocol behind the Workspace ↔ pid2 WebSocket (and in general, the protocol behind the Workspace ↔ * WebSocket).

Since the pid2 services are declared in TypeScript using TypeBox in the main repl-it-web repository, and it would be terrible for everyone involved to force folks to follow this paradigm of declaring their services, types, and interfaces in a foreign repository, any other River servers will use gRPC for their protocol definition and implementation. The @replit/river-codegen package can be used to compile the gRPC .proto files into a River-compatible TypeBox declaration that can be then packaged into an npm package that can be imported by the Workspace and consumed ergonomically.

This includes the necessary machinery to act as a client or server for River:

• As a River server, create a WebSocket server and the gRPC -> Python River codegen (similar to the protoc flow that generates the Python bindings).
• As a River client, create a WebSocket client and the JSON Schema -> Python River codegen. python -m river.codegen client --output pkgs/river/river/schema.py --client-name Pid2Client pkgs/river/schema.json
• If we need to create the client-side of a Python gRPC River server, we also need to generate the JSON schema from the .proto file, with this command: python -m river.codegen server-schema --output pkgs/river/river/schema.py pkgs/river/tests/client/proto/test.proto && cat ./test_schema.json

Publishing

Release Drafts

Pending releases are curated by release-drafter/release-drafter on the Releases page.

Maintainers can see the next Draft release, regenerated every time release-drafter.yml is triggered.

PR Labeling

PRs merged since the last release are considered, with the labels on those PRs used for release metadata. feature, bug, chore, and dependencies are used for categorization, major, minor, and patch are used to influence the next release's version.

These labels can be altered after merge, re-trigger release-drafter to get it to regenerate the draft once you've curated the next release.

Triggering release

The tag version is used to set the version during the build, the value in pyproject.toml is not expected to be kept up-to-date.
