multi currency account

If you were to implement a multi-currency version of Medici, how would you do it?

I guess

.debit('Assets:Cash', 1000, {meta}) would need another parameters, ie: .debit('Assets:Cash', 1000, {meta}, "USD")

A transaction would still equal out with multiple currencies. ie Alice sending 10 USD for 12 EUR to Bob:

.credit('Alice', 10,  {}, 'USD')
.debit('Bob", 10, {}, USD')
.debit('Alice', 12,  {}, 'EUR')
.credit('Alice, 12, {}, 'EUR')

Now the issue would be that, if we try to fetch a balance like this, we will have currency co-mingled.

ie:

const balance = await myBook.balance({
  account: "Assets:Accounts Receivable",
  client: "Joe Blow"
});

So we would need to have a mandatory currency field here. And filter that out.

I’m wondering what the most efficient way to do it would be?

Simply adding a currency field in transaction, and modifying the balance function? Any other idea?

I have currently being using

.credit('Alice', 10,  {currency: 'USD'})
.debit('Alice', 9, {currency: 'EUR'})
.credit('Bob', 9,  {currency: 'EUR'})
.debit('Bob', 10, {currency: 'USD'})

with no issue so far. as long as every balance() call includes currency the balance seems correctly fetch with the currency flag.

closing this for now.
