**Scenario**
When writing business logic, this code typically lives within services. With complex situations, there can be lots of business logic exceptions or messages being created. In order to have the best user experience, we try to display detailed messages to the end user so if it's an error with some data, they know what they need to do to correct the situation. Sometimes this is through a message on a page, an email, etc. In some cases a generic message might be displayed and we log the message instead or send the message in an email to a 3rd party.
The service shouldn't need to care how the message is going to be handled, but just needs to create it in a way that it can be translated if needed.
**Options**
Translating when the message is created. There are two issues with this approach. Autowiring the translator interface to services that will display an error isn't ideal as it will increase the dependencies the service has. The larger issue is that because we would be throwing an exception that contains a string or passing a message that's a string (what the translator returns), if we have generic twig templates that run the translator function on a message, we're doing a double translation and the debug toolbar will indicate that there is a missing message and turn red. This makes finding missing translations much more difficult as we have to determine if there are any false positives and turns the red indicator into white noise.
Translating when displaying on a template. This option is possible, but adds complexity to our templates. Each time we display a message, we need to have some kind of logic that checks to see if it should be ran through the translator as-is or we need to get the data from the object and pass into the translator.
**Proposed Solution**
Adding a Phrase object that we can create and pass around reduces the template complexity and adds a nice way to create objects that can be translated at any point. This something that will be very familiar with Magento developers and other platforms also have similar solutions.
**TODO**
- [x] Determine if overwriting the parameters should be allowed (currently implemented this way)
- [x] Determine the name of the translatable class, currently `Phrase` as `Message` will likely get confused with Messenger
- [x] Determine if there should be a global function to allow quickly creating these. Similar to `__()` in Magento
- [ ] Add docs
- [x] Add tests
Happy to get as much feedback as possible. I know a feature like this would be very welcomed by my team.
