In 2012, Emily Bache started a collection on GitHub of three katas specifically selected for use in a Legacy Code Retreat (Tennis, Yahtzee, and Gilded Rose) and invited others to contribute, and contribute they did. The result, in at least 5 languages, can be found here. Although that work included links over to Cyber-Dojo, those links no longer work.
So, I re-ported the work over to Cyber-Dojo, added attribution and a link back to the github repo at the bottom of the instructions pages, and renamed the code and test sources to reflect the exercises. Here are the keys on Cyber-Dojo:
Lang: ["Tennis", "G Rose", "Yahtzy"],
CSharp: ["53C59C", "294BBB", "D08160"],
CPP: ["3DA231", "77146E", "FE4865"],
Java: ["876748", "19E971", "7FD3B4"],
JS: ["14DFAF", "E9C44B", nill ],
Python: ["461D9A", "C38077", "0EB11E"],
Ruby: ["239135", nill, "1C1D6A"]
There's even more on Emily's Github repo, but Cyber-Dojo doesn't offer SmallTalk (unless someone has forked CD somewhere so that it does?!).
Thank you Emily. These made for a GREAT legacy code retreat.
