bloop VS dotty

Here's the links: * bloop: https://scalacenter.github.io/bloop/ * terminal to IDE (iTerm only): https://alexn.org/blog/2021/07/18/iterm-open-file-cmd-click-ide-semantic-history.html * Switching between JetBrains' and standard typechecker in IDEA: Options -> Languages and Frameworks -> Scala -> Editor tab -> Error highlighting

If you look at the Build Tools section of the Metals documentation, you'll see how Metals supports sbt. It is admittedly a bit of a roundabout process: Metals first imports the sbt build definition into a tool called bloop that implements the Build Server Protocol that Metals relies on for metadata, compilation, etc. for the project.

Jorge Vican had finished some work on this in the past, but this feature was abandoned (for now). As u/tgodzik has pointed out, there is not enough interest for this in the community (thanks for replying btw.).

Dotty? Was it still the name later?

I think this might be related to this issue.

You can look (and EPFL collect feedback) about EPFL implementation of async/await: https://github.com/lampepfl/async. Also you can look at dotty ticket about this: https://github.com/lampepfl/dotty/pull/16739

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

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.

By the way, you might be interested in this recent PR which overhauls the scala 3 macro docs: https://github.com/lampepfl/dotty/pull/17060.

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).

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

im glad to tell you that in 3.3.0 a lot of these -Wunused lints will be supported: see https://github.com/lampepfl/dotty/pull/16157
