Application scripts

Application scripts are used to extend the program's functionalities, like verify the accounting or build custom reports. This functionality is available only in Banana Premium or Banana Experimental.

With the dialog "Manage Scripts" from the "Account1" menu, you can install, modify or remove scripts. The script can be located everywhere, usually they are in the same folder as the accounting file.

Example to check for duplicates transactions (download script with test accounting).

Note: Instead of showing a message, it had could be possible to list the rows (like the command extract) in a separated table with the command Banana.Document.Table.extractRows().

// This script verify if there are duplicate transactions in the book accounting.
// Duplicate transactions have the same Doc, DateDocument, and Customer's Account
