Information and Resources related to the Crystal Programming Language
Crystal is a programming language with the following goals:
  • Have a syntax like Ruby (but compatibility with Ruby is not a goal)
  • Statically type-checked but without having to specify the type of variables or method arguments
  • Be able to call C code by writing bindings to it in Crystal
  • Have compile-time evaluation and generation of code, to avoid boilerplate code
  • Compile to efficient native code

Why Crystal

Security: we can distribute a single static binary in a docker container, there is little chance of exploit.
Speed: the binaries are fast, see Spider-Gazelle.
Developer happiness: all the benefits of Go Lang with the elegance of Ruby.
