Wrong scalac option suggested about scala3-migrate HOT 2 CLOSED

I'm not using -Yrangepos yet I get an X for that

@reibitto in some cases a scalacOptions can be added by another setting or plugin. For instance -Yrangepos is added by sbt-scala3-migrate itself. The plugin needs it to run Scalafix in the migrateSyntax command.

So the good news is you don't need to do anything about it. But I don't really know how to make this clearer in the output because sometime -Yrangepos is added manually so people need to know it is not available anymore...

the -Xfatal-warnings suggestion seems backwards.

That's true. All the -W and -V options were added in Scala 2.13 quite recently and unfortunately we don't have them yet in Scala 3. This is planned, but for now we have to do without them.

A good resource for comparing the Scala 3 and Scala 2.13 options is https://scalacenter.github.io/scala-3-migration-guide/docs/compiler-options/compiler-options-table.html

I wasn't sure if I should report this separately or bucket it into this one, but I also noticed some possible issues with the options suggested.

I'm not using -Yrangepos yet I get an X for that. Also, the -Xfatal-warnings suggestion seems backwards.

Edit: The -Xfatal-warnings one might not be backwards if that's the one that Scala 3 wants. I thought that because I'm not using -Werror in my build file, yet that's what it seems to think I have set.
