At minimum, 3 parameters are required (in this order):

1 - the dollar amount
2 - a description
3 - the expense account name must be specified. 

The transaction will default as an expense. The withdrawal account will default to 'Liabilities:Credit Card' when not specified.

A positive dollar amount will be added into the Expense:{Name} account. A negative dollar amount will be added into the Liabilities/Account.

Two more paramters exist to change the Account and switch Expense to Income

4 - the account (liabilities, checking, savings, etc)
5 - income

This allows you to expense or add income to another account.

Note: The command 'transaction' (transaction.bat) is synonymous with 'python2 parser.py'

transaction '$9.00,The Martian,Books'

Success: ($9.00) "The Martian" Expenses:Books from Liabilities:Credit Card

transaction '$16.00,The Martian,Entertainment:Movie,Checking'

Success: ($16.00) "The Martian" Expenses:Entertainment:Movies from Account:Checking

transaction '1000000,Making Bank,Salary,Checking,Income'

Success: ($1,000,000) "Making Bank" Income:Salary into Assets:Current Assets:Checking Account

transaction '5.00,Climbing Gym Day Pass,Sports'

Success: ($5.00) "Climbing Gym Day Pass:, Expenses:Sports from Liabilities:Credit Card

Note: The account Expenses:Sports did not exist and was automatically created.

CC as 'Liabilities:Credit Card'
Checking as 'Assets:Current Assets:Checking Account'
Savings as 'Assets:Current Assets:Savings Account'

When an expense comes in referenece a non-existant expense account, that expense account will be automatically created. All other missing accounts will redirect to Imbalance. I decided to only automatically create expense accounts, this seemed safe. Should the "from" account (like CC or checking) not exist, it will redirect to Imbalance. If income comes in and either the TO (where to deposit) or FROM (what type of income was this, like Salary) accounts do not exist, both can redirect to Imbalance.

Imbalance allows the user to recognize an error in gnucash and correct transactions. Imbalance will highlight RED.

Unless there is a problem connecting to the file, this should allow all transactions to process into the database.
