Globalization for strings

[mttrbrts]

Ergo should allow for strings in messages, such as in enforce statements, to be globalized / localized.

@mttrbrts Could you provide an example of how it might look like at the Ergo language level?

[mttrbrts]

Perhaps something like :

enforce count(request.shipment.sensorReadings) > 0.0
    otherwise localize("no-readings", "fr-FR") ;

Could the locale even be an implicit property of the contract instance? This would allow something like:

enforce count(request.shipment.sensorReadings) > 0.0
    otherwise localize("no-readings") ;

Where localize uses state.locale for the lookup?

We should have this discussion in the context of globalization of Cicero templates too. For example, specifying the locale for a template should select the correct template grammar and propagate through to the logic.

Thanks this is helpful.

Localization can be implemented as a library, I imagine?

[jeromesimeon]

I think @kach is correct about using a library, except for the implicit use of state.locale?
