This is a basic proof of concept for using Go generics in our Go
SDK. There were a number of "on the fly" design decisions made:
* Replace Input altogether.
* Keep Output[T], but it needs to be a struct largely due to the
lack of generics support in the Go reflection library.
* Introduce AnyOutput as a base interface that all Output[*]s
implement, which lets us treat any "outputtish" things uniformly.
This is enough to get the basic hello, world working:
package main
import (
"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)
func main() {
pulumi.Run(func(ctx *pulumi.Context) error {
var bucket Bucket
if err := ctx.RegisterResource("aws:s3/bucket:Bucket", "myBucket", pulumi.Map{}, &bucket); err != nil {
return err
}
ctx.Export("bucketName", bucket.Bucket)
nameLength := pulumi.Apply(bucket.Bucket, func(name string) int {
return len(name)
})
ctx.Export("bucketNameLength", nameLength)
return nil
})
}
There are plenty of embarassing hacks needed to get this to work,
and some blatent omissions too. For instance, I doubt Any works, and
obviously the tests won't run clean. Nevertheless, I wanted to save/
archive/share this work in the event that it's helpful to someone.

Pulumi Golang SDK
This directory contains support for writing Pulumi programs in the Go language. There are two aspects to this:
pulumi/contains the client language bindings Pulumi program's code directly against;pulumi-language-go/contains the language host plugin that the Pulumi engine uses to orchestrate updates.
To author a Pulumi program in Go, simply say so in your Pulumi.yaml
name: <my-project>
runtime: go
and ensure you have pulumi-language-go on your path (it is distributed in the Pulumi download automatically).
By default, the language plugin will use your project's name, <my-project>, as the executable that it loads. This too
must be on your path for the language provider to load it when you run pulumi preview or pulumi up.
