Crystal programming language is super interesting. I've spent the time checking out Crystal and digging through what is available, and wrote it all down as I learned. Who are you? I'm Serdar Dogruyol, and I've been a Crystalist for years now. I'm the author of Kemal, curator of Crystal Weekly and a Crystal Core Member. I love new programming languages, and while I've been using Ruby for the past y
Have you heard about Crystal Programming Language? It’s been over 3 years since we saw its first version, but if you’re not familiar with it, it’s a statically typed, compiled language with a very Ruby-esque syntax. This has at least three implications: With static types, we are more likely to catch some errors before shipping our code (yes, I’m looking at you NoMethodError for nil:NilClass 🙄)Com
Years ago a number of developers had the collective thought experiment “what if we took Ruby-like syntax and wrote a fast-as-C, general-purpose, typed language that (like C/C++) compiles to native binaries on any platform but keeps high level goodies like a rich standard library, full fibers support, etc?” Fast forward a few years and this dream has manifested itself in the Crystal programming lan
Crystal is a very interesting project that I have been following for the last couple of months. There is no 1.0 release yet (but it’s close) so I haven’t really used it in any production systems, but its newness makes it a very good language to get into open source. If you check out their site, the tag line for Crystal is “Fast as C, slick as ruby”. Basically it has a very similar syntax to Ruby,
This is a guest post by Mark Siemers, who kindly volunteered to suggest a series of Crystal blog posts. Expect more to come, or - even better - contact us about writing your own post. 1. Extremely low learning curve Think of some languages that have become popular in the last 5-10 years. What comes to mind? Elixir, Go, Rust perhaps? They all have performance advantages over Ruby but are more diffi
Almost 1 year ago, riding the wave of end of year optimism, Manas.Tech (“we” from here on in this post) decided to commit to wrap up a 1.0 release during 2017 that would include all possible breaking changes to the language. As with many other new year’s resolutions, this was wishful thinking. At the time of our post, things felt a little closer than what they actually were. Also, due to an influx
Crystal? Some of you may have heard about it in the best TV series of all the time, Breaking Bad! Thankfully, we're not gonna talk about drugs in this post, but about a fabulous programming language I've heard of recently. In my constant quest to discover new languages and paradigms, I came across Crystal. Crystal is a compiled, statically typed, and object-oriented language. Its syntax is strongl
This year, the Crystal team launched the first official State of Crystal survey. We’re amazed by the fantastic feedback from the community. We received 757 responses. Thanks a lot to everyone who took the time to respond! We tried our best to read through all of your comments and suggestions. Without further ado, let’s take a look at the results. How did you discover Crystal? (hover for more info)
