TemplateManager is a class that's been around for years and nobody really knows who coded
it or how it really works. Nonetheless, as the business changes frequently, this class has
already been modified many times, making it harder to understand at each step.
Today, once again, the PO wants to add some new stuff to it and add the management for a new placeholder. But this class is already complex enough and just adding a new behaviour to it won't work this time.
Your mission, should you decide to accept it, is to refactor TemplateManager to make it
understandable by the next developer and easy to change afterwards. Now is the time for you to
show your exceptional skills and make this implementation better, extensible, and ready for future
features.
Sadly for you, the public method TemplateManager::getTemplateComputed is called everywhere,
and you can't change its signature. But that's the only one you can't modify (unless explicitly
forbidden in a code comment), every other class is ready for your changes.
This exercise was made to not last longer than 1 hour but we know that this can be too short to do it all and you might take longer if you want. Stop when you feel you've done something you feel comfortable sharing with us.
You can run the example file to see the method in action.
There are some rules to follow:
- You must commit regularly
- You must not modify code when comments explicitly forbid it
What do we expect from you:
- the link of the git repository
- several commits, with an explicit message each time
- a file / message / email explaining your process and principles you've followed
Good luck!
