hledger - a ledger-compatible accounting tool.
|
|
Copyright (c) 2007-2010 Simon Michael <simon@joyful.com>
|
|
Released under GPL version 3 or later.
|
|
|
|
hledger is a partial haskell clone of John Wiegley's "ledger". 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 .
|
|
|
|
This module provides the main function for the hledger command-line
|
|
executable. It is exposed here so that it can be imported by eg benchmark
|
|
scripts.
|
|
|
|
You can use the command line:
|
|
|
|
> $ hledger --help
|
|
|
|
or ghci:
|
|
|
|
> $ ghci hledger
|
|
> > j <- readJournalFile "data/sample.journal"
|
|
> > register [] ["income","expenses"] j
|
|
> 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
