Instance Method Details

#validate ⇒ Object

Reviews every transfer, and post, to ensure that there are no tags occurring more than once, in any given entry. Unlike most of the validations in RVGP, this one doesn’t use ledger or hledger to validate. This validation parses the file itself, in ruby, and ensures based on the contents.
