    Dotty? Was it still the name later?

    The reason I’m not currently an opaque type user as they do not play well with the tagless final style we use, though I am patiently awaiting some attention on my bug report: https://github.com/lampepfl/dotty/issues/17281

  • About Scala-Native
    4 projects | /r/scala | 13 Apr 2023
    Scala Native has much more control on how the Scala AST is compiled, and can easier workaround platform limitations, eg. lazy vals in Scala 3 required reflection config for Native Image (see this and that), while in Scala Native we could mitigate problems with unsupported usage inside in other ways within the compiler plugin.

    For example, this issue (https://github.com/lampepfl/dotty/issues/12840) was blocking the migration, it was reported more than a year ago and the fix was finally released a month ago (https://github.com/lampepfl/dotty/releases/tag/3.3.0-RC2).
  • scala 3 does not have :javap. Does anyone have any tips how to get around this.
    2 projects | /r/scala | 22 Feb 2023
    For the record, there is an implementation of :javap which is close to being done but might need a volunteer to get it over the finish line: https://github.com/lampepfl/dotty/pull/12210

    Ahhh no unused warnings, thats disappointing to say the least. I guess some progress is being made here https://github.com/lampepfl/dotty/pull/16157 , tbh this kind of stuff makes me want to stick to Scala 2.

  • First Slick prerelease for Scala 3!
    2 projects | /r/scala | 9 Jul 2023
    Made a PR on slick to document this https://github.com/slick/slick/pull/2760 (workaround is quite easy, you can just define def tupled = (apply _).tupled in the companion object of the case class and it will also compile for all Scala versions).

  • Sketch of a Post-ORM
    14 projects | news.ycombinator.com | 2 Jun 2023
    The Scala ecosystem has a few ways to do composable type-safe query building, e.g. Slick[0] or more recently Quill[1]. . I believe both also have ways to do compile-time string interpolation (e.g. sql"""select * from users where id = ${user.id}""") which generate prepared statements (I know Slick does prepared statements. Quill has similar macros but I haven't looked into how safe they are to use).

    With all this in mind, I landed at the first candidate: slick from https://scala-slick.org/ that you all probably know.

  • Is there any good resource for learning Slick (3.x)?
    2 projects | /r/scala | 2 Sep 2022
    https://github.com/slick/slick/pull/2097 now I use slightly lower version of slick so this might be an upgrade that resolves (I do recall using it in 21 and it was still buggy and I filed a ticket, which I cannot find at the moment), but given a complex enough query (we have one in PROD which has tons of flexibility in terms of filters that can be passed in) but it also makes for complex code.
  • Slick 3.4.0 is imminent
    2 projects | /r/scala | 16 Aug 2022
    I started writing a reply but then I realized it would be long and depends on exactly what you mean, so maybe it's better to post the question in https://github.com/slick/slick/discussions/categories/questions?
    2 projects | /r/scala | 16 Aug 2022
    You can see the draft release notes here and the upgrade guide at https://scala-slick.org/doc/prerelease/upgrade.html#upgrade-from-3-3-x-to-3-4-0. The latest docs are at https://scala-slick.org/doc/prerelease/index.html.
