If you're interested, take a look at Crystal (https://crystal-lang.org/)! - Source: Hacker News / 5 months ago

Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago. If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly... - Source: Hacker News / 6 months ago

Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well. Source: 6 months ago

Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything. My modern programming toolkit is basically golang + ruby + bash and I am never left wanting. I do find Crystal (https://crystal-lang.org/) really... - Source: Hacker News / 6 months ago

How is this different from Try It Online https://tio.run ? - Source: Hacker News / almost 2 years ago

Given your PL interpreters are written in Python, why not just share them as Python programs, optionally bundled with CPython? Are you concerned abput having a CPython dependency? PLs like Scala or Kotlin or Clojure depend on a backend (JVM, JS), so why not your PL? Or is the issue absolute simplicity? In which case, I suggest aiming at making it available via an online evaluator such as tio.run -- which boils... Source: over 2 years ago

TIO is actually quite good for that, even if it's more commonly associated with code golf. https://tio.run/. Source: over 2 years ago

Try It Online[0] seems to offer a very similar service - if you don't care about the collaboration aspect of it. It claims to be self-hostable[1]. glot.io[2] is another, which seems to fit more in the realm of "pastebin with runnable snippets". As I understand it, a big sell of repl.it is that they have some kind of collaborative editing support, which none of the alternatives I was able to find in a few minutes... - Source: Hacker News / almost 3 years ago
