In Crystal 0.27.0 releasedWindows support is... not good.
http://github.com/crystal-lang/crystal/issues/26
In Crystal 0.27.0 releasedCrystal is a Ruby inspired compiled language, allowing it to run blazingly fast with a very low memory footprint. It uses LLVM for emitting native code, thus making use of all the optimisations built into the toolchain.
Website: https://crystal-lang.org/
Github: https://github.com/crystal-lang/crystal
In Crystal on Windows: A Deep Dive on Exception HandlingIndeed, and there seems to have been some work done to great effect[0]. Unfortunately the corresponding branch is quite stale[1].
Anyway, my comment was more about the fact that the "Concurrency / Add multithreading support" section of the roadmap was quite unclear about parallelism. Mentioning MRI's GIL was merely an example as to why any kind of thread interlocking could turn things into non- (or very limited) parallelism, hence patagonia's question being quite legitimate.

In Crystal 0.26.0 releasedNo note of parallelism on the roadmap?
https://github.com/crystal-lang/crystal/wiki/Roadmap
In Crystal 0.26.0 releasedCrystal looks interesting although I decided to learn Golang instead. It's more mature and the WIP features described below made me cautious (i.e. what other features are immature).
Anyone know when Crystal will get concurrency-a-la-golang? i.e. running concurrent processes in parallel? At the moment I think it's still single-threaded. https://crystal-lang.org/docs/guides/concurrency.html
Still no windows support: https://github.com/crystal-lang/crystal/issues/5430
In Crystal 0.25.1 releasedWe use Crystal at RainforestQA to replace our heavy-load / slowish Ruby microservices. It's been great so far and we love it. We're also increasing the adoption to Crystal inside the organization.
Also Crystal has a dedicated a wiki page for production users
Used in production: https://github.com/crystal-lang/crystal/wiki/Used-in-product...
In Crystal 0.25.1 releasedI had a crack at fixing this. Could you try my make_portable.sh script on one of your Crystal binaries?
https://github.com/crystal-lang/crystal/issues/3067#issuecom...
In Crystal 0.25Seems like the most relevant issue is here: https://github.com/crystal-lang/crystal/issues/3067#issuecom...
In Crystal 0.25I really, really like Crystal — the Ruby syntax is great, and better type safety is always a plus.
But I haven't found a reliable way for building a binary on a Mac OS without requiring dyld already be present on the target user's system. Seems none of the following issues are resolved, or that the project has indicated a recommended way to do this?
https://github.com/crystal-lang/crystal/issues?utf8=%E2%9C%9...
In Crystal 0.25I'm confused about the state of threading in Crystal. See the last message in : https://github.com/crystal-lang/crystal/issues/1967#issuecom...
I'm hoping to see more languages with light-weight threads automatically mapped (multiplexed) to physical threads, like in Go. So far, based on the crowd-sourced table I started working on, it is otherwise only Ada, Haskell and Pony (in addition to Go) that seems to meet these criteria:
https://docs.google.com/spreadsheets/d/1BAiJR026ih1U8HoRw__n...
In Crystal 0.25If anyone is looking for companies that are using it in production (like I was), here's a list: https://github.com/crystal-lang/crystal/wiki/Used-in-product...
Crystal always fascinates me when it gets brought up, and I'd really like to dive in sometime.
In Crystal 0.25I've been keeping my eye on Crystal for a while now thinking about making the plunge and writing something production ready in it.
But I'm a bit vary as for the casual observer the Crystal project github (https://github.com/crystal-lang/crystal) seems brim with unsolved issues (over 500 issues!) and stale PR-s (over 105!). I'm not sure if this is a sign of poor project managment, development stall or poor community engagement but still it leaves a bad first impression. Contrast this to elixir project page (https://github.com/elixir-lang/elixir).
Maybe someone who is actively involved in the development of Crystal could shine a light?
