uv run with stdin #6467
Description
inspired by https://docs.astral.sh/uv/guides/scripts/#declaring-script-dependencies and some tweets being able to just send someone a command and boom they can run a py script
MRE:
billy@sa ~/uv_eof % uv run - <<EOF
print("hello world")
EOF
error: Failed to spawn: `-`
Caused by: No such file or directory (os error 2)Short dash(-) here represents stdin, similar to how k8s allows:
kubectl apply -f - <<EOF
apiVersion: v1
kind: ServiceAccount
metadata:
name: kubectl-actions
namespace: my-v2-restore
EOFSome more details and how kubectl does it (in go tho ofc) https://stackoverflow.com/a/72168173/9992341 and https://github.com/kubernetes/cli-runtime/blob/v0.21.0/pkg/resource/builder.go#L245
basically turns any snippet someone else wants to run with
billy@sa ~/uv_eof % curl -LsSf https://astral.sh/uv/install.sh | sh && uv run - <<EOF
print("hello world")
EOF
