NAME

GnuCash::SQLite - A module to access GnuCash SQLite files

VERSION

version 0.09

SYNOPSIS

use GnuCash::SQLite;

# create the book
$book = GnuCash::SQLite->new(db => 'my_accounts.gnucash');

# get account balances
$on_hand = $book->account_balance('Assets:Cash');
$total   = $book->account_balance('Assets');

# check if book is locked by another application
die "Book is currently used by another application." 
  if $book->is_locked;

# add a transaction
$book->add_transaction({
    date         => '20140102',
    description  => 'Deposit monthly savings',
    from_account => 'Assets:Cash',
    to_account   => 'Assets:aBank',
    amount       => 2540.15,
    number       => ''
});

# access internal GUIDs
$book->account_guid('Assets:Cash');     # GUID of account
$book->commodity_guid('Assets:Cash');   # GUID of currency 

DESCRIPTION

GnuCash::SQLite provides an API to read account balances and write transactions against a GnuCash set of accounts (only SQLite3 backend supported).

When using the module, always provide account names in full e.g. "Assets:Cash" rather than just "Cash". This lets the module distinguish between accounts with the same name but different parents e.g. Assets:Misc and Expenses:Misc

METHODS

Constructor

$book = GnuCash::SQLite->new(db => 'my_account.gnucash');

Returns a new GnuCash::SQLite object that accesses a GnuCash with and SQLite backend. The module assumes you have already created a GnuCash file with an SQLite backend and that is the file that should be passed as the parameter.

If no file parameter is passed, or if the file is missing, the program will terminate.

account_balance

$book->account_balance('Assets:Cash');   # always provide account names in full
$book->account_balance('Assets');        # includes child accounts e.g. Assets:Cash

Given an account name, return the balance in the account. Account names must be provided in full to distinguish between accounts with the same name but different parents e.g. Assets:Alice:Cash and Assets:Bob:Cash

If a parent account name is provided, the total balance, which includes all children accounts, will be returned.

add_transaction

$deposit = {
    date         => '20140102',
    description  => 'Deposit monthly savings',
    from_account => 'Assets:Cash',
    to_account   => 'Assets:aBank',
    amount       => 2540.15,
    number       => ''
};
$book->add_transaction($deposit);

A transaction is defined to have the fields as listed in the example above. All fields are mandatory and hopefully self-explanatory. Constraints on some of the fields are listed below:

date         Date of the transaction. Formatted as YYYYMMDD.
from_account Full account name required.
to_account   Full account name required.

CAVEATS/LIMITATIONS

Some things to be aware of:

1. You should have created a GnuCash file with an SQLite backend already
2. Module accesses the GnuCash SQLite3 db directly; i.e. use at your own risk.
3. Only transactions between Asset accounts have been tested.
4. Only two (2) splits for each transaction will be created

This module works with GnuCash v2.4.13 on Linux.

SEE ALSO

GnuCash wiki pages includes a section on C API and a section on Python bindings which may be of interest.

C API          : http://wiki.gnucash.org/wiki/C_API
Python bindings: http://wiki.gnucash.org/wiki/Python_Bindings

This module does not rely on the C API (maybe it should). Instead it relies on some reverse engineering work to understand the changes a transaction makes to the sqlite database. See http://wideopenstudy.blogspot.com/search/label/GnuCash for details.
