Improve chord build errors

[gsouf]

Hi,

I have a work in progress where user can type their one chord, and this goes to the chord builder. It's very straightforward because the chord parser does the analysis of the user input for me.

My goal today it to display error to the user in his language. I could translate the error message that the library return, but it is definitively a bad solution (and moreover the error returned contains some variables).

I have though about 2 obvious way to fix it (and both can be implemented together).

• 1 - add a translation to the library that we can pass globaly to teoria at the runtime, and we can return already translated messages to the user
• 2 - throw a different exception for each error : this would be very helpful. It will allow to know what is going wrong before telling the user it's wrong. Then we can adapt the action we want the user to achieve to fix it.

obviously, we can mix both solution and throw different exception with translated message.

Hi @SneakyBobito,

We should definitely go for option 2. We could do this by returning/throwing an error with a constant error symbol.

I'll look into this, if you don't want to?

I can do it for sure. Just give me a few time.
