They, however, are usually made to be generic and allow many people to use them, so sometimes we need to do something extra that is specific to our use case in order to make things work properly. The fact that we cannot really modify the original library code means that we have to do something different. Something that we have already looked at is the decorator and the adapter design pattern. Well, pimp my library achieves something similar, but it does this in the Scala way and some of the extra work is given to the compiler to deal with.

The pimp my library design pattern is really similar to extension methods in C#. We will see some examples in the following subsections.

Using the pimp my library

The pimp my library design pattern is really easy to use. Let's see an example in which we want to add some useful methods to the standard String class. Of course, we cannot modify its code, so we...
