Your Help Needed
If you know Crystal, please write code for some of the tasks not implemented in Crystal.
If you know Crystal, please write code for some of the tasks not implemented in Crystal.
Crystal is a programming language with the following goals:
- Have the same syntax as Ruby, or at least as similar as possible.
- Never have to specify the type of a variable or method argument.
- 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.
You can ask for help on Freenode in the #crystal-lang channel.
