I found Crystal about a year ago and absolutely fell in love with it. It just “clicks” for me. My sense from reading most peanut-gallery commentary that the biggest reasons it hasn’t taken off more (yet) are: 1. Real multi-threading (it’s now in alpha - but previously just had single-threaded concurrency - and sorry I might be getting that terminology wrong). 2. Windows support (I personally don’t care but I haven’t…

Does anyone actually care about Windows support?

I have had a huge amount of issues trying to use both Ruby and Rust on Windows for server / client use cases. It's not just that it "works" on Windows, but that it works easily out of the box for common use cases.

Meanwhile Python and Golang work great on Windows with no extra effort. It's like night and day.

Wow. Preemptive multitasking, graphical window management, POSIX-like, in a programming language that to my knowledge it hasn't yet been done in... and in just several months of work. There's no smoke and mirrors as far as I can tell. I dug back to the initial commit: https://github.com/ffwff/lilith/commit/c9fa1053dc6a22d630ee6... - and it's just bootstrapping to VGA. Very well done, and inspiring. Makes me want to t…

When does GC kick in during the boot sequence? And how are you managing memory? Is the whole OS mark and sweeped?

Maybe it's just because I come from Ruby, but Crystal seems like an amazing language. I'm interested why it seems to be getting little attention compared to Go, Rust, & Julia. It seems in the same league to me. Kotlin and Swift have more obvious reasons for their adoption.

> I'm interested why it seems to be getting little attention compared to Go, Rust, & Julia. Rust essentially competes with C and C++ (and maybe D and Nim without their GCs), and the reason it gets hype is because it brings some unique features for that niche. Go brought some unique features as well (goroutines done right), and it is pushed by a major player. In Julia's niche, you only really have Julia and Fortran -…

Why Erlang processes are not right?

You are aware that Windows thoroughly dominates the Desktop computing space right?

That's like recommending Office via Wine in 2001.

Not in the slightest. WSL is capable for most things. Wine in 2001 was not usable

The problem with wsl is that its a window like a small island extending 1000m into the air, and the moment you step off... Splat, you're back in Windows with the registry and such. I bought a surface a few weeks back - wsl is nothing but an improved cygwin, of no use to Linux/Mac users, and windows has become repulsively spammy. I've installed arch.

> C#, Kotlin and Swift are the system API languages of major platforms (MS, Apple, Android). No, the system API of those systems is exposed in C, ObjC and C respectively. You may be thinking about the most common language in those platforms nowadays (and their respective APIs).

It's still C all the way down, even in 2019. Amazing how far crappy, badly thought out, ubiquitous, low entry barrier languages can go. More than 40 years of memory errors, out of bounds errors, broken metaprogramming, undefined behavior, lack of error handling, type safety, abstractions and intelligent design in general, all served under the clunky syntax sauce. And it still powers our world. Worse is better, indeed.

What's Crystal's unique selling point? It's older than Rust, Kotlin, Swift, Nim, or even OCaml, and doesn't really offer anything they don't. More Ruby-like syntax? Fine, but most people don't particularly like Ruby syntax.

It's unique selling point is union types as a part of the type system, with whole-program type inference and flow typing. This has never been done before (as far as I am aware), and it is incredibly powerful and interesting. It's compile-time duck typing.

>whole-program type inference and flow typing

What do these mean?

Yes. Although I'd rather use Linux, most company IT will distribute windows computers and will not give you a Linux laptop. That means a lot of your work will be done on Windows.

Erlang is just too different from the C-like languages that everyone is accustomed to.

Right after the global descriptor table is setup and paging is enabled, the GC is then enabled. On every allocation, and whenever the os has no task available to switch to, a gc cycle is performed.

Not really, the kernel and any process written in crystal has a garbage collector, any other userspace process can manage memory however they want to.
