Plugin request for Buf Schema Registry: protoc-gen-connect-php #2851

Mandatory

Where is the source code for the plugin?

https://github.com/ftshp/connect-php/tree/main/cmd/protoc-gen-connect-php

The plugin is part of ftshp/connect, an unofficial PHP implementation of the Connect protocol (unary RPCs, PSR-18 client, PSR-15 server). For each service it generates a PHP interface and a client class next to the message classes from protocolbuffers/php. Streaming RPCs are skipped with a warning.

Optional

Does the plugin have a valid semver version?

v0.1.0, from the GitHub release: https://github.com/ftshp/connect-php/releases/tag/v0.1.0. Releases are tagged v* and built with goreleaser. go install github.com/ftshp/connect-php/cmd/protoc-gen-connect-php@v0.1.0 builds the same binary.

Does the plugin have a dependency on another plugin?

Yes, on protocolbuffers/php (https://github.com/protocolbuffers/protobuf/tree/main/php) for the message classes, like connectrpc/go on protocolbuffers/go. The generated code follows the namespace mapping and reserved-name rules of protoc-gen-php, so both plugins have to run on the same files.

Does the output of this plugin depend on any other external libraries?

Yes, the ftshp/connect Composer package (https://packagist.org/packages/ftshp/connect, Apache-2.0) and google/protobuf.

Proposed name: buf.build/community/ftshp-connect-php. The Dockerfile follows the connectrpc/go one (static Go build of the tagged module, scratch runtime, nobody user). I have the plugin directory and the plugin.sum files ready and will open the PR once this issue is in.
