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.

All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.
We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.
The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.
We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.
Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.
The course includes lunch that we use in a restaurant within walking distance of the course room.
The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.
At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.
The intellectual property rights of the published course content, also referred to as an information sheet, belong to SpiralTrain. It is not allowed to publish the course information, the information sheet, in written or digital form without the explicit permission of SpiralTrain. The course content is to be understood as the description of the course content in sentences as well as the division of the course into modules and topics in the modules.
