In order for `include SentencesParser` to work with Zeitwerk, we'd have
to change the code slightly, so it follows Ruby conventions to resolve
constants:
```
module RemoteTranslations::Microsoft
class Client
include SentencesParser
# (...)
end
end
```
This would mean changing the indentation of the whole file. While we can
do that, changing the indentation of a file makes it harder to use
commands like `git blame` or `git log` with the file, so we're doing the
change the easy way.
The purpose of the lib folder is to have code that doesn't necessary
belong in the application but can be shared with other applications.
However, we don't have other applications and, if we did, the way to
share code between them would be using a gem or even a git submodule.
So having both the `app/` and the `lib/` folders is confusing IMHO, and
it causes unnecessary problems with autoloading.
So we're moving the `lib/` folder to `app/lib/`. Originally, some of
these files were in the `app/services/` folder and then they were moved
to the `lib/` folder. We're using `app/lib/` instead of `app/services/`
so the upgrade is less confusing.
There's an exception, though. The `OmniAuth::Strategies::Wordpress`
class needs to be available in the Devise initializer. Since this is an
initializer and trying to autoload a class here will be problematic when
switching to Zeitwerk, we'll keep the `require` clause on top of the
Devise initializer in order to load the file and so it will be loaded
even if it isn't in the autoload paths anymore.
