hledger - a ledger-compatible text-based accounting tool.

hledger is a minimal haskell clone of John Wiegley's "ledger" text-based
|
|
accounting tool (http://newartisans.com/software/ledger.html). hledger
|
|
generates ledger-compatible register & balance reports from a plain text
|
|
ledger file, and demonstrates a functional implementation of ledger. For
|
|
more information, see the hledger home page: http://joyful.com/hledger
|
|
|
|
You can use the command line:
|
|
|
|
> $ hledger --help
|
|
|
|
or ghci:
|
|
|
|
> $ ghci hledger
|
|
> > l <- ledgerfromfile [] "sample.ledger"
|
|
> > balance [] [] l
|
|
> $-1 assets
|
|
> $2 expenses
|
|
> $-2 income
|
|
> $1 liabilities:debts
|
|
> > register [] ["income","expenses"] l
|
|
> 2007/01/01 income income:salary $-1 $-1
|
|
> 2007/01/01 gift income:gifts $-1 $-2
|
|
> 2007/01/01 eat & shop expenses:food $1 $-1
|
|
> expenses:supplies $1 0
