ledgercalc

A simple multifunction + variables RPN calculator for Ledger (http://www.ledger-cli.org)

Works with Ledger 3 when compiled with the python interface

Must be run via ledger python ledgercalc.py <journalfile> start_year end_year <commandfile>...

An example is included, run it with:

ledger python ledgercalc.py example.lgr 2012 2014 example.commands

Syntax

Syntax is RPN, so an operation like

account1 account2 + 

adds two accounts, pushes result onto stack.

Accounts containing spaces/regex must be put in double quotes.

Variables are prefixed with $, and are assigned like this:

$taxrate 0.091 = 

Numbers are bare, but amounts less than decimals have to be preceded by a 0 (good: 0.15, bad: .15)

Comments start with #

Output

Output is a list of all variables assigned during each run in varname = <amount> format

Known Bugs

Currently only supports the USD currency.

Account regex parsing isn't the same as ledger, due to the way the python interface works.
