Hi Fred
I use a solution similar to yours for sharing expenses with my partner in
ledger-cli. For beancount I have made a (very simple) plugin that does pretty
much the same. I have attached the plugin which you might find useful. It is
used like this:
plugin "bc_plugins.split_expenses" "Assets:Receivable"
2019/05/22 * Bakery
Expenses:Food 10.00 EUR
split: "Susa"
Assets:Cash
The plugin transforms the transaction into the following:
2019/05/22 * Bakery
Expenses:Food 5.00 EUR
Assets:Receivable:Susa 5.00 EUR
Assets:Cash
Regards,
Michael
