Description

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.

Synopsis

Posting

nullposting :: Posting Source

posting :: Posting Source

post :: AccountName -> Amount -> Posting Source

operations

postingCleared :: Posting -> Bool Source

Is this posting cleared? If this posting was individually marked as cleared, returns True. Otherwise, return the parent transaction's cleared status or, if there is no parent transaction, return False.

isReal :: Posting -> Bool Source

isVirtual :: Posting -> Bool Source

isBalancedVirtual :: Posting -> Bool Source

isEmptyPosting :: Posting -> Bool Source

hasAmount :: Posting -> Bool Source

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.

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 ?

isPostingInDateSpan' :: WhichDate -> DateSpan -> Posting -> Bool Source

postingsDateSpan :: [Posting] -> DateSpan Source

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

postingsDateSpan' :: WhichDate -> [Posting] -> DateSpan Source

account name operations

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

accountNamePostingType :: AccountName -> PostingType Source

accountNameWithoutPostingType :: AccountName -> AccountName Source

accountNameWithPostingType :: PostingType -> AccountName -> AccountName Source

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 applicable aliases from the given list, in sequence.

accountNameApplyOneAlias :: [AccountAlias] -> AccountName -> AccountName Source

Rewrite an account name using the first applicable alias from the given list, if any.
