`scala-cli config interactive true` should be on by default
Version(s) 0.1.12
Describe the bug
Beginners don't know --main-class and it is natural to have the sbt-like UX when multiple mains give selection out of the box.
To Reproduce Create multiple mains and the user gets an error.
Expected behaviour
The user should be presented with a choice and scala-cli config interactive true should be the default as this is IMHO better UX for beginners.
The user already is presented with this choice.
The first time the --interactive flag is passed, Scala CLI will ask if you want it on permanently.
▶ scala-cli . --interactive
You have run the current scala-cli command with the --interactive mode turned on.
Would you like to leave it on permanently?
[0] Yes
[1] No
0
--interactive is now set permanently. All future scala-cli commands will run with the flag set to true.
If you want to turn this setting off at any point, just run `scala-cli config interactive false`.
Found several main classes. Which would you like to run?
[0] ScalaMainClass2
[1] ScalaMainClass1
[2] scripts.ScalaScript_sc

Afterwards, the --interactive flag does not have to be passed anymore.

Unless you meant it should be turned on by default-by default. As in, that the choice should be presented even if the --interactive flag is never passed.
Which is something we can't really do, as there's a high probability that scala-cli is operated by a bot/automation rather than a human. So we wait for --interactive to be passed at least once, first.
Well the beginner programmer might not know about the --interactive option.
At least the error message of the multiple main class missing option should excplain how to use both --main-class and --interactive. Would that be ok?
I have updated the initial description to include this proposed behavior. (I didn't think about the bot use case... but informative text doesn't bother bots :robot: )

Yeah, sure. This now looks like a duplicate of #1315, so let's track it there. Closing this ticket.
