virtualenv venv
. venv/bin/activate
pip install -r requirements.txt
Copy config.example.yml to config.yml (or set the LEDGER_PYREPORT_CONFIG environment variable to the path to the config file).
Run as per a usual Flask app, for example:
FLASK_APP=ledger_pyreport python -m flask run
Notes on Ledger setup
ledger-pyreport expects each of assets, liabilities, equity, income and expenses to be setup in Ledger as a separate top-level account. These accounts should contain a zero balance, with all transactions in child accounts.
Additionally, ledger-pyreport expects the next level of assets and liabilities to be categories of asset and liability (e.g. Assets:Current, Liabilities:Non-current). These, too, should contain a zero balance.
Ledger-pyreport by default observes the convention that positive amounts in Ledger represent debits, and negative amounts in Ledger represent credits.
A commodity which has any price data in Ledger (including those specified through @ or @@, or explicitly through P) will be regarded as a commodity measured at fair market value, and automatically revalued accordingly. A commodity which has no price data in Ledger (i.e. lot prices through {…} or {{…}} only) will be regarded as a commodity measured at historical cost, and will not be subsequently revalued.
