Just hoping to see if we can view print statements in rego code to be rendered as output when using Gator CLI so that debugging/developing a policy can be much faster.

It looks like print statements are not currently printed.

An interim option would be to use the trace() statement and set the --trace flag, which should inject text into the Rego trace. This is probably a better method for development/debug, as more contextual information is provided.

For potential implementation...

Printing could be enabled by setting the appropriate PrintEnabled() and PrintHook() arguments in the Rego driver:
