I've been doing lots of little Scala projects that want to send e-mail, including HTML e-mail. The Scala mail lib I found was a bit elaborate (based on cats effects) for my purposes. JavaMail (now Jakarta mail) is annoying to use directly.

So, I wrote a little mailutil library that is pretty trivial to send mail with, and straightforward to configure.

Maybe someone else finds it fun. https://github.com/swaldman/mailutil

Typo is such a game changer for working with #PostgreSQL. Point it to your DB and raw SQL queries and It generates nicely typed #Scala mappings for different DB libraries.

Includes streaming support not only for reading queries but also super fast streaming inserts for your tables via COPY.

I've been using it on a project for a few weeks now and I love how much boilerplate it removes and just generally simplifies things.

I highly recommend you to give it a try: https://oyvindberg.github.io/typo/

Since other people are discussing these things, always a good reminder that on #scala using cats-effect library and using #FunctionalProgramming these thing are properly abstracted away nowadays and on daily usage one finally barely has to care at all about it. - https://typelevel.org/cats-effect/docs/thread-model

#fedicode #Scala #codeReview

Hello fediversian,
How do you handle the review process (as in "sharing knowledge and insights, getting feedback" on a very big PR?

OK, the best solution is "do not do big pr" and yes, scaling down the issue is generally a good advice (either by splitting the thing in an iterative process, or in several topic commit)
I did that, but the resulting change is still big (+30k/-100k of Scala) and impactful (switch a core part of the app), the two being of course intrinsically linked.
It could have been "work in pair", but that horse is far away already.

So, I did my homework (create arch docs and schema, document the change "how to get into that pr" way, tracked all the code change that made me pause in code log, added unit test to both demonstrate non regression on old behavior and new one, document code, etc) .

Still, such a change is frightening, just by the involvement and time needed to get at the "I can review" level.
But I really need to help them at that level, since the pr embed technical and functional knowledge important to be shared, even if not for getting feedback on the code now.

So: how do I help my team getting involved in that pr? It really looks like the next step must be interactive ("let me walk the changes with you, ask anything you want" like). Do you have any recommendations or guidelines about how to do that efficiently?

I wish #Scala 3 opaque types had an easy way to derive the operations of the underlying type. Something like #Haskell `deriving newtype` with the ability to point out which operations you want.

I guess one should eventually be able to use this UI framework with #scala native or scala.js.

The Vale Programming language

We also discovered that they (Generational References) enable Vale to have complete memory safety, something no native language has been able to achieve.

• No borrow checker
• No GC
• Writes like Go with a hint of Scala
• FFI interop
• No unsafe blocks
• No comptime related keywords

Why you should learn #StronglyTypedFunctionalProgramming

From Martin Odersky's talk about #Scala https://youtu.be/7mTNZeiIK7E

#haskell #functionalprogramming

I like #Kotlin, but it's not value-oriented or even as expression-oriented as #Scala is. And the difference can be subtle, but as a Scala dev, I feel it even for simple tasks.

Here's a simple function. The Kotlin code cannot describe a tail-recursive function, as it's forced to be “inline”, due to “reification”. Scala's “inline” functions can be tail-recursive, and inlining isn't even needed for reification.

You may like while-loops, the point being in Scala it's easier to avoid mutability.

#Scala #Scalajs #Scala3

Out of the Alt-JS languages I've played with, #Scala.js seems to be the best.

Given it's probably not widely adopted, its maturity is surprising. E.g., ScalablyTyped can convert TypeScript definitions, and actually works. Interop is good. And the compiler is, dare I say it, pretty fast compared to 2–3 years ago. Scala 3 also helps. E.g., it has untagged unions, just like TypeScript.

I'm surprised that it's in better shape than #KotlinJS, for all its multi-platform marketing.

#Scalajs #Scala3

What I really like about #Kotlin is that the popular libraries tend to be based on common-sense. You look at a sample, and you understand it.

Here's a sample that I discovered and understood in seconds, showing me how to define reusable CLI sub-commands in multiple subprojects: https://ajalt.github.io/clikt/commands/

#Scala's libs in this space (case-app, decline, mainargs, scopt,...) are based on compiler magic or weird data structures, have poor docs, and I can't tell if they get the job done 🤷‍♂️

In Scala 3, these utilities are guilt-free. But I can't find them in the stdlib optimized yet: https://www.scala-lang.org/api/3.3.1/scala/util/ChainingOps.html

#scala #scala3 #pic

I'm doing simple dev with #scala, #zio, #doobie, #quicklens, #specs2, #postegresql, and others things and it's very pleasant. I really like the programing level : not forced to care about low level stuff, data driven, types forbidding whole classes of problems and allowing fearless refactoring while I'm discovering the domain, with systematic and composable error management so that it's a pleasure to manage them accurately.

It's relaxing

Programming in Java, anything non-trivial is still, “death by a thousand cuts”.

This is why alternative languages running on top of the JVM will always be relevant (e.g., #Scala, #Kotlin, #Clojure, #JRuby), especially if they strive to be more than just Java++. Because Java++ is the same boring old Java.

The redeeming quality that Java has is the extreme backwards compatibility. But this doesn't really speak for the libraries that people use, upgrades are still hard & classpath hell is real.

Anyone else getting tired of #Rust getting the credit for (G)ADTs?

No? Just me?

#ocaml, #haskell, #StandardML, and #scala among others had this long before Rust and without the complexity of the borrow checker or lifetimes. Rust moves this concept of type system as bug prevention system forward for systems programming, but there is a long history of good compilers (targeting application development, not systems) that did this already (and in a few cases - better!). I am tiring of the narrative that Rust is the ”*only* memory safe language"...

#Gradle supports different options to write plugins. This is good, because it gives you the choice to use what fits your context. Any you should always write plugins - if only to organize your project's build configuration.

But it is confusing 😖. That's why I created this overview:
https://github.com/jjohannes/gradle-plugins-howto

Learn by exploring the difference between writing the same Gradle plugins in:

- Gradle Kotlin DSL
- Gradle Groovy DSL
- #Java
- #Kotlin
- #Groovy
- #Scala
- #Clojure

Why bother with tagless final if you're only ever gonna stick to one effect system, right? It's like those Java folks arguing over javax interfaces when they know they'll never swap tomcat/jetty in their production system. But here's the deal: you don't use them for switching implementations in one project, but to make life easier when shifting people between different projects. You know, get them up to speed fast! And that's possible if they know both implementations play nice with a shared spec.

#Python has batteries included in its stdlib, but when those batteries aren't enough people have to resort to installing pip + virtualenv + pyenv, alongside the OS's native packager, which they still need for native dependencies.
