playground: recognize // GOEXPERIMENT=foo lines at top of source file

We sometimes add features we want people to play with to the Go toolchain
using GOEXPERIMENT flags. Provide access to these on the playground by
looking for // GOEXPERIMENT=foo lines at the top of source files.

In particular, this will let people add // GOEXPERIMENT=loopvar and get
the loop variable semantics.

playground

Go Reference

This subrepository holds the source for the Go playground: https://go.dev/play/

Building

# build the image
docker build -t golang/playground .

Running

docker run --name=play --rm -p 8080:8080 golang/playground &
# run some Go code
cat /path/to/code.go | go run client.go | curl -s --upload-file - localhost:8080/compile

To run the “gotip” version of the playground, set GOTIP=true in your environment (via -e GOTIP=true if using docker run).

Deployment

Deployment Triggers

Playground releases automatically triggered when new Go repository tags are pushed to GitHub, or when master is pushed on the playground repository.

For details, see deploy/go_trigger.yaml, deploy/playground_trigger.yaml, and deploy/deploy.json.

Changes to the trigger configuration can be made to the YAML files, or in the GCP UI, which should be kept in sync using the push-cloudbuild-triggers and pull-cloudbuild-triggers make targets.

Deploy via Cloud Build

The Cloud Build configuration will always build and deploy with the latest supported release of Go.

gcloud --project=golang-org builds submit --config deploy/deploy.json .

To deploy the “Go tip” version of the playground, which uses the latest development build, use deploy_gotip.json instead:

gcloud --project=golang-org builds submit --config deploy/deploy_gotip.json .

Deploy via gcloud app deploy

Building the playground Docker container takes more than the default 10 minute time limit of cloud build, so increase its timeout first (note, app/cloud_build_timeout is a global configuration value):

gcloud config set app/cloud_build_timeout 1200  # 20 mins

Alternatively, to avoid Cloud Build and build locally:

make docker
docker tag golang/playground:latest gcr.io/golang-org/playground:latest
docker push gcr.io/golang-org/playground:latest
gcloud --project=golang-org --account=you@google.com app deploy app.yaml --image-url=gcr.io/golang-org/playground:latest

Then:

gcloud --project=golang-org --account=you@google.com app deploy app.yaml
