A Posting represents a change (by some MixedAmount) of the balance in some Account. Each Transaction contains two or more postings which should add up to 0. Postings reference their parent transaction, so we can look up the date or description there.




postingStatus :: Posting -> Status Source #

Get a posting's status. This is cleared or pending if those are explicitly set on the posting, otherwise the status of its parent transaction, or unmarked if there is no parent transaction. (Note the ambiguity, unmarked can mean "posting and transaction are both unmarked" or "posting is unmarked and don't know about the transaction".

postingAllTags :: Posting -> [Tag] Source #

Tags for this posting including any inherited from its parent transaction.

transactionAllTags :: Transaction -> [Tag] Source #

Tags for this transaction including any from its postings.

removePrices :: Posting -> Posting Source #

Remove all prices of a posting

date operations

postingDate :: Posting -> Day Source #

Get a posting's (primary) date - it's own primary date if specified, otherwise the parent transaction's primary date, or the null date if there is no parent transaction.

postingDate2 :: Posting -> Day Source #

Get a posting's secondary (secondary) date, which is the first of: posting's secondary date, transaction's secondary date, posting's primary date, transaction's primary date, or the null date if there is no parent transaction.

isPostingInDateSpan :: DateSpan -> Posting -> Bool Source #

Does this posting fall within the given date span ?

postingsDateSpan :: [Posting] -> DateSpan Source #

Get the minimal date span which contains all the postings, or the null date span if there are none.

account name operations

accountNamesFromPostings :: [Posting] -> [AccountName] Source #

Sorted unique account names referenced by these postings.

joinAccountNames :: AccountName -> AccountName -> AccountName Source #

Prefix one account name to another, preserving posting type indicators like concatAccountNames.

concatAccountNames :: [AccountName] -> AccountName Source #

Join account names into one. If any of them has () or [] posting type indicators, these (the first type encountered) will also be applied to the resulting account name.

accountNameApplyAliases :: [AccountAlias] -> AccountName -> AccountName Source #

Rewrite an account name using all matching aliases from the given list, in sequence. Each alias sees the result of applying the previous aliases.

accountNameApplyAliasesMemo :: [AccountAlias] -> AccountName -> AccountName Source #

Memoising version of accountNameApplyAliases, maybe overkill.

transaction description operations

payeeAndNoteFromDescription :: Text -> (Text, Text) Source #

Parse a transaction's description into payee and note (aka narration) fields, assuming a convention of separating these with | (like Beancount). Ie, everything up to the first | is the payee, everything after it is the note. When there's no |, payee == note == description.
