hledger - a ledger-compatible text-based accounting tool.
Copyright (c) 2007-2009 Simon Michael <simon@joyful.com>
Released under GPL version 3 or later.
hledger is a partial haskell clone of John Wiegley's "ledger" text-based
accounting tool. It generates ledger-compatible register & balance
reports from a plain text journal, and demonstrates a functional
implementation of ledger. For more information, see http:\/\/hledger.org .
You can use the command line:
> $ hledger --help
or ghci:
> $ ghci hledger
> > l <- readLedger "sample.ledger"
> > register [] ["income","expenses"] l
> 2008/01/01 income income:salary $-1 $-1
> 2008/06/01 gift income:gifts $-1 $-2
> 2008/06/03 eat & shop expenses:food $1 $-1
> expenses:supplies $1 0
> > balance [Depth "1"] [] l
> $-1 assets
> $2 expenses
> $-2 income
> $1 liabilities
> > l <- myLedger
> > t <- myTimelog
See "Ledger.Ledger" for more examples.
