Would you like to replace print_r with an HSL function?

Would you like to replace print_r with an HSL function?

Hey Atry, thanks a lot. I'd love to, but I wasn't able to find an appropriate HSL function for printing dictionaries. Echo also doesn't work. Would it be possible to help me with this. Many many thanks!

Thank you so much for your help! Would the following be the right way to use it as IO\request_output also doesn't have too many documentations.

$values = vec[1, 2, 3, 4];
$dict = Dict\from_values($values, $x ==> $x + 1);
IO\request_output($dict);

I was trying to learn from previous examples and I found both Dict.select_keys and Dict.groupby were using print_r in the existing documentation: https://github.com/hhvm/user-documentation/blob/main/api-examples/function.HH.Lib.Dict.select_keys.md

All tests passed locally, and the webpage also looks fine.

When I switched to request_output, and ran the following in the vscode debugger, nothing was given as output. And when I ran build, and looked at the website in through the server, it looked like the below. It would be awesome if you can provide some help, many thanks!

See https://docs.hhvm.com/hack/getting-started/input-and-output for basic usage of request_output.
