    The Crystal Programming Language

    Project mention: Ronin 2.0.0 has finally been released! Ronin is a free and Open Source Ruby toolkit for security research and development. | | 2023-02-02

    Why yes, I am a big fan of Crystal and actually presented at the first online Crystal Conf in 2020. I am actually trying to port some of my Ruby libraries over; not that I want to replace Ruby with Crystal, but that I want my same libraries in both languages so I can easily switch between them. I do want to port some of the Ronin libraries over to Crystal for use-cases when you need to create a compiled binary, but that would require first porting the other Ruby gem dependencies, such as my hexdump or wordlist gems. However, porting some of these libraries proved more difficult than I expected, due to Crystal being compiled, lacking an Enumerator class (aka Generators), and other semantic/type-system rules. Porting Ruby code to Crystal really makes you appreciate how the Ruby VM can handle all sorts of code and "just work", where as Crystal needs to compile everything down to finite machine code. It's definitely "on the roadmap", but there's still a lot of work to do.

    Fast, Effective, Simple Web Framework

    Project mention: How do you find the market in 2023? | | 2023-01-06

    It's been around for a while under development. It had it's 1.0.0 release in March 2021. There's been two (online) Crystal conferences, and there's two Crystal books published. There's a decent ecosystem of "shards" and there are a couple of Crystal web frameworks and ORMS that are similar to Sinatra or Rails-like. If you already know Ruby, learning Crystal is super easy.

    Interactive console for Crystal programming language

    Project mention: Crystal's Interpreter (2021) | | 2022-06-26

    it's had an IRB-like REPL for years. It just wasn't built into the language. Admittedly it was limited compared to IRB but it was more than enough to test out quick ideas.

    It's called ICR: Interactive Crystal

    the first release was back in 2017

    A Language Server Protocol implementation for Crystal. 🔮

    Project mention: Speed & LSP | | 2022-08-08

    I just tried to get crystalline working, and it seems to be working surprisingly well. Performance is and always will be an issue with LSP for Crystal, though. Crystal by its nature compiles slowly. Although, perhaps this will be helped by the new "interpreted" mode?
