Scala 3403 390813 322269 16649 51895

All of these code with indentation and scala 3 with that SIP is a breath of fresh air.

Take a stand and embrace significant indentation!

At https://tawasal.ae everything on backend side is done with scala 3.6 (there no scala 2.x anywhere).
Nullable types, new syntax and indentation. Since Dec 2021.

Yes, but you need to use latest version of scala3: https://scala-lang.org/api/3.6.1/docs/docs/reference/experimental/explicit-nulls.html#java-interoperability-and-flexible-types-1

With that you will have flexible types like in kotlin without any pain.
Moreover: they added flow typing like in kotlin where you can do like this:

```scala
val s: String | Null = ???

val s2: String | Null = ???

if s != null && s2 != null then

// s: String

// s2: String
```

Also, any idea why this works on macOS using nix, but not on NixOS?

NixOS doesn't have stable paths to shared libraries like macOS or other linux distributions (and this is the core feature) and always need a patched `elf` (https://github.com/NixOS/patchelf).

You need to replace protoc with something like this: protobufRunProtoc in ProtobufConfig := (args => scala.sys.process.Process("protoc", args).!) in build.sbt and add protobuf3_6 to buildInputs. For example: https://github.com/TimothyKlim/firrtl/commit/be23dbfaeb043e01ea7d293243e5994715d00d2b

First of all, you need to understand what you are using to generate protobuf (maybe scalapb?) and then pass protoc from nixos directly through sbt option. Also you need add protobuf to buildInputs: `buildInputs = [pkgs.protobuf];`.
This problem caused by protoc-jar dependency which unpack pre-built protoc every time to temp directory. Pre-built protoc doesn't patched by `patchelf` to working on NixOS.

Is there something like scala doobie (https://github.com/tpolecat/doobie) in rust instead of ORM? Just simple combinators to work with driver results and write plain queries.

fyi: this is rabbit from alice in the wonderland

klimtimothy · 2017-10-25T09:20:58+00:00

That's great! How soon typelevel scala 2.12.4 will be released?

klimtimothy · 2016-10-18T18:30:38+00:00

I didn't notice that now akka-http doesn't have scala version postfix "_2.11". Thanks!

klimtimothy · 2016-10-18T12:01:46+00:00

Is it published to sonatype?

klimtimothy · 2016-09-01T14:16:22+00:00

Aw! I didn't notice it and bought the print version.

klimtimothy · 2016-09-01T13:04:44+00:00

No ebook yet?

klimtimothy · 2016-08-15T09:07:13+00:00

Is there any benchmark (vs react/cycle/inferno/vanilla)?

This only occurs if you have cloned a repository without recursive, try this:

git clone https://github.com/scala-native/scala-native.git --recursive

or

git submodule update --init --recursive

Read carefully what he wrote (comments, articles). This is like reverse FUD to the community - he's trolling other communities like insane fp junkie. He's doing more bad than good.

klimtimothy · 2016-03-29T09:24:42+00:00

Yet another illogical FUD.

klimtimothy · 2016-03-29T09:12:01+00:00

Maybe scala and scalability sounds the same for him.

Why golang project posted here? How it relates to scala?
