CFONB Parser

This parser aim at simplifying the parsing of CFONB structured files. Which are files structured with either 120 or 240 characters lines containing mostly bank statements. We aimed here only at the 120 characters version.

Requirements

None.

Installation

gem install cfonb

Or, put it in your Gemfile:

gem 'cfonb'

Available Operation Details

OperationDetails are lines starting with 05. They aim at providing additional information about the operation. Below is the list of additional details available for each operation.

These details can be accessed through operation.details, which will provide all the attributes. To fetch a specific attribute, you can use operation.details.attribute. For example, operation.details.unstructured_label. Ultimately, you can also access the 70 characters of the detail by using its code like operation.details.mmo

If you encounter new ones, please open an issue or a pull request with the appropriate implementation. We aimed at making it as easy as possible to add new details. You just need to do the following on initialization:

CFONB::OperationDetails.register('FEE', self)
