@eed3si9n Could you please review my pr? The failed CI check is flaky one, isn't related to my change |

You got the arrows key to work? |

@eed3si9n Looks like all CI checks have passed |

Yea, a slight conundrum is that I started making some improvements on the common parts between console and compile #8584 (like using URI instead of String), so if I merge this, I'd need to follow up with some changes afterwards. And I can't land the forked compile one because all the tests haven't passed. I can review this PR soon, if you're ok with some of the changes in this PR getting overwritten soon. The repl specific parts should mostly stay intact. |
