take yaml on stdin

[aclater]

It would be handy if podlet could take compose.yaml (or other) on stdin, so that one could use it in a pipeline of tools that output yaml or simply cat compose.yaml | podlet

Nevermind - I see this already works, you simply have to tell podlet what its taking in:

cat compose.yaml | podlet compose

Not exactly, podlet compose, if you don't specify a file, will look for a compose file in the current directory. So in your given example podlet is just ignoring the stdin and finding the compose.yaml file in your current directory.
This behavior is documented in podlet compose --help in the [COMPOSE_FILE] section:

$ podlet compose --help

Generate podman quadlet files from a compose file

Creates a `.container` file for each service, a `.volume` file for each volume, and a `.network` file for each network.

The `--file` option must be a directory if used.

Some compose options are not supported, such as `build`.

When podlet encounters an unsupported option, an error will be returned. Modify the compose file to resolve the error.

Usage: podlet compose [OPTIONS] [COMPOSE_FILE]

Arguments:
  [COMPOSE_FILE]
          The compose file to convert
          
          If not provided, podlet will look for (in order) `compose.yaml`, `compose.yml`, `docker-compose.yaml`, and `docker-compose.yml`, in the current working directory.

Options:
      --pod <POD>
          Create a Kubernetes YAML file for a pod instead of separate containers
          
          A `.kube` file using the generated Kubernetes YAML file will also be created.

  -h, --help
          Print help (see a summary with '-h')

If your curious it is implemented here.

I will add reading from stdin if the given path is - in the next version.

Ah! That explains it.
