Piped text causes rainbowstream to repeat its prompt forever

[ShadowKyogre]

Steps to Reproduce

1. Run the following: echo h | rainbowstream

Expected Result

Have the prompt appear after it's done interpreting commands from the pipe.

OR

Bail after it's done receiving things over the pipe.

Actual Result

rainbowstream understands the input, but the prompt keeps repeating forever.

See https://asciinema.org/a/3k4rj1xg0aeonycyq3ju2tp69 for more information.

Also, while the prompt is garbled, that's an entirely different issue that already has a PR to fix it.

Thanks - will look further into it

Just tried the same thing and the prompt still repeats forever. Would be nice to be able to do this. Sample use case would be echo t test | rainbowstream to send a quick tweet.

After watching the video link and seeing what is supposed to happen, mine does the same thing. Was being a bit slow on the uptake.

BUMP

has anyone figured this out?

You may need to pass the carriage returns (to terminate the tweet) and exit() to close rainbowstream again:

echo 't hello world\n\nexit()' | rainbowstream
