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.
