Add Syntax Changes document #8301
Conversation
Add a doc page to explain how the syntax of previous Dotty versions changed in 0.22.

I think this should be kept as a doc page somewhere, but we don't need to link prominently to it. I put it under release-notes. Not sure whether there is a better place. What's the doc tool doing these days? If we merge this PR, will it be accessible immediately? And under what URL? |
| import a.{given _} | ||
| import b.{_, given _} | ||

| The previous syntax, which used just `given` without an underscore is no longer supported. The change was made to better align with typed given import selectors such as `given Ordering[T]`, |

no longer supported
On 0.22.0-RC1, it's still possible to do import Foo.given https://scastie.scala-lang.org/SnWyIoLBROW2VI2kuq8kJA

Yes, 0.22 RC is maximally permissive. It's on master that the old forms are removed.

@odersky the link should be http://dotty.epfl.ch/docs/release-notes/syntax-changes-0.22.html, the doc tool generates a website from everything in "docs/". It will become accessible after the next nightly build. If we don't explicitly put it in the sidebar YAML file, it won't appear there. Do we also need to update the 0.22 website snapshot to have that page (accessible via http://dotty.epfl.ch/0.22.0-RC1/docs/release-notes/syntax-changes-0.22.html)? |

Thanks for the explanations. I'll make a post linking to the page tomorrow then. I don't see a reason why we should have it in the snapshot (or on the sidebar). |
