go-protoc-gen-swift
go-protoc-gen-swift is a distribution of the protoc-gen-swift.
It does not actually reimplement any functionality of swift-protobuf in Go, instead compiling it
to WebAssembly, and executing with the pure Go Wasm runtime wazero.
This means that go install or go run can be used to execute it, with no need to rely on external
package managers such as Homebrew, on any platform that Go supports.
Installation
Precompiled binaries are available in the releases.
Alternatively, install the plugin using go install.
$ go install github.com/wasilibs/go-protoc-gen-swift/cmd/protoc-gen-swift@latest
As long as $GOPATH/bin, e.g. ~/go/bin is on the PATH, you can use it with protoc as normal.
$ protoc --swift_out=out/swift -Iprotos protos/helloworld.proto
For buf users, to avoid installation entirely, it can be convenient to use go run in buf.gen.yaml.
version: v1
plugins:
- plugin: swift
out: out/swift
path:
- go
- run
- github.com/wasilibs/go-protoc-gen-swift/cmd/protoc-gen-swift@latest
This makes it possible to have full protobuf/gRPC generation with no installation of tools,
besides Go itself, on any platform that Go supports. The above examples use @latest, but it is
recommended to specify a version, in which case all of the developers on your codebase will use the
same version of the tool with no special steps.
See a full example in go-protoc-gen-builtins. To generate protos, enter the directory and run
go run github.com/bufbuild/buf/cmd/buf@v1.30.0 generate. As long as your machine has Go installed,
you will be able to generate protos. The first time using go run for a command, Go automatically builds
it making it slower, but subsequent invocations should be quite fast.
