Recently I added a Read-Eval-Print-Loop-Console (REPL)-console to the aruba-project as playground for our users similar to the one you find in rails. This article first shows you aruba’s console a bit and then describes how you can build your own console in Ruby with some help of IRB.
Having a suite testing a lot of features is a good thing. But if your project supports a lot of different Rubies – MRI-Ruby, JRuby etc. – you might face platform dependent bugs. Read on, if you like to know how we worked around some platform dependent bugs in aruba to keep the build status “green” on all support Rubies.
ENV makes the environment variables of the running process available within a Ruby-script. But there is a subtle difference in implementation between MRI-Ruby and JRuby. Unfortunately that difference broke some aruba-builds on Travis.
