Hi!

Thanks! I'm glad that my content is helpful to you! I didn't describe the Interpreter pattern simple because it is very rare and quire complex. As a software developer with 20 years of experience you could have used all 22 patterns but that one. I like to share this link when answering the questions about Interpreter: http://blogs.perl.org/users/jeffrey_kegler/2013/03/the-interpreter-design-pattern.html

There is a big irony in fact that I had used the Interpreter pattern to build the engine for live examples, which are part of the Refactoring Course. A live example looks pretty much as a short video which shows the sequence of refactoring steps. The actions that take place in a live examples in fact are being interpreted from a scenario like this one: https://raw.githubusercontent.com/RefactoringGuru/refactoring-examples/master/interactive/java/add-parameter.md

I've just pushed an update that should prevent roll-backs in progress in scenarios you've described. I'm really sorry for the inconvenience you've experienced. Hopefully, this won't be an issue anymore. Please let me know if you still experience the weirdness with the progress saving.

Hi!

Well, it suppose to save your progress. Do you, by any chance, open topics in new tabs? That might cause issues with saving the progress.

Hi Rafael,

Thanks for your feedback. Why do you think it's incorrect?

Здравствуйте, Артём!

Нет, пока ещё нет.

Спасибо на добром слове! Рад, что вам всё понравилось.

Здравствуйте!

Спасибо, что интересуетесь! Книга — о паттернах, курс — о рефакторинге. В данный момент они не пересекаются по содержимому, поэтому да, смысл есть.
