It's the end of financial year, and now that I'm accounting with NZD,USD,JPY,BTC I've spent some time to automate the pricedb process. Enjoy :) PR's welcome.

Tool that uses Yahoo finance to intelligently generate a ledger price database based on your current ledger commodities and time period.

Ensure that you have set the LEDGER and LEDGER_PRICE_DB environment variables before proceeding. Alternatively, you can make the same addition to your .ledgerrc, so long as running ledger vanilla knows where to get the journal and pricedb.

• LEDGER_BASE_CURRENCY: Defaults to USD, change this to your reporting currency.
• LEDGER_PRICE_DATE_FORMAT: The date format of the outputted pricedb. Defaults to %Y/%m/%d.

gem install ledger_get_prices
getprices # This will WRITE to your LEDGER_PRICE_DB file.
