;; We can "use" dynamic dispatch in a language without it manually ;; Our "objects" will have: ;; * an immutable list of mutable "fields" (symbols and contents) ;; * an immutable list of immutable "methods" (symbols and functions taking self) (struct obj (fields methods)) ; like ...
Ruby is a general-purpose programming language that is dynamic, self-reflective, and based on objects. It was made by Yukihiro Matsumoto and is the purest form of an Object-Oriented language. Except for the blocks, everything in Ruby is an object. However, you can use procs and lambdas ...
Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible....
Informal Abstract People who write Ruby programs want to use metaprogramming. It’s part of what makes the language what it is. But in existing implementations of Ruby, metaprogramming is slow. My work focused on making it fast, providing fast tooling for Ruby programmers, and fast support for...
To manipulate objects, use the functions supplied by the Ruby interpreter. Some (not all) of the useful functions are listed below: String Functions¶ ↑ rb_str_new(const char *ptr, long len) Creates a new Ruby string. rb_str_new2(const char *ptr) rb_str_new_cstr(const char *...
