In the course Ruby Programming participants learn to program in Ruby using the syntax and language constructs of that language.
After an introduction about the background of Ruby, the installation and the way in which code can run, the variables, data types and control flow are discussed.
Attention is also paid to methods and parameter passing in Ruby and to object oriented aspects such as classes, objects, inheritance and polymorphism.
The handling of errors through exception handling is discussed as well.
The course continues with a discussion of partitioning code into modules, modules as namespaces and mixins as the use of modules from the standard library.
Also closures such as blocks, lambdas and Procs are discussed and Ruby meta programming is treated with introspection, Open Classes and dynamic method invocation.
Finally writing RubyGems is on the course schedule and an overview of the capabilities of the Standard Library is given.
The course Ruby Programming is intended for experienced developers who want to learn the Ruby scripting language.
Knowledge and experience with programming in another programming language, such as C, C++, C#, Visual Basic, Java or Perl is required.
The theory is discussed on the basis of presentation slides and is interspersed with practical exercises. Illustrative demos provide further clarification of the concepts. The course material is in English.
Participants receive an official certificate Ruby Programming after successful completion of the course.
