Hledger.Data.Posting

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.

Posting

nullposting :: Posting

posting :: Posting

post :: AccountName -> Amount -> Posting

Make a posting to an account.

vpost :: AccountName -> Amount -> Posting

Make a virtual (unbalanced) posting to an account.

balassertTotInc :: Amount -> Maybe BalanceAssertion

operations

originalPosting :: Posting -> Posting

postingStatus :: Posting -> Status

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".

isReal :: Posting -> Bool

isVirtual :: Posting -> Bool

isBalancedVirtual :: Posting -> Bool

isEmptyPosting :: Posting -> Bool

hasBalanceAssignment :: Posting -> Bool

hasAmount :: Posting -> Bool

postingAllTags :: Posting -> [Tag]

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

transactionAllTags :: Transaction -> [Tag]

Tags for this transaction including any from its postings.

relatedPostings :: Posting -> [Posting]

postingStripPrices :: Posting -> Posting

Strip all prices from a Posting.

postingApplyAliases :: [AccountAlias] -> Posting -> Either RegexError Posting

Apply some account aliases to the posting's account name, as described by accountNameApplyAliases. This can fail due to a bad replacement pattern in a regular expression alias.

postingApplyCommodityStyles :: Map CommoditySymbol AmountStyle -> Posting -> Posting

Choose and apply a consistent display style to the posting amounts in each commodity (see journalCommodityStyles).

postingAddTags :: Posting -> [Tag] -> Posting

Add tags to a posting, discarding any for which the posting already has a value.

date operations

postingDate :: Posting -> Day

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

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.

postingDateOrDate2 :: WhichDate -> Posting -> Day

Get a posting's primary or secondary date, as specified.

isPostingInDateSpan :: DateSpan -> Posting -> Bool

Does this posting fall within the given date span ?

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

account name operations

accountNamesFromPostings :: [Posting] -> [AccountName]

Sorted unique account names referenced by these postings.

comment/tag operations

commentJoin :: Text -> Text -> Text

Join two parts of a comment, eg a tag and another tag, or a tag and a non-tag, on a single line. Interpolates a comma and space unless one of the parts is empty.

commentAddTag :: Text -> Tag -> Text

Add a tag to a comment, comma-separated from any prior content. A space is inserted following the colon, before the value.

commentAddTagNextLine :: Text -> Tag -> Text

Add a tag on its own line to a comment, preserving any prior content. A space is inserted following the colon, before the value.

arithmetic

sumPostings :: [Posting] -> MixedAmount

Sum all amounts from a list of postings.

rendering

showPosting :: Posting -> String

showPostingLines :: Posting -> [Text]

Render a posting, at the appropriate width for aligning with its siblings if any. Used by the rewrite command.

postingAsLines :: Bool -> Bool -> Int -> Int -> Posting -> ([Text], Int, Int)

Render one posting, on one or more lines, suitable for print output. There will be an indented account name, plus one or more of status flag, posting amount, balance assertion, same-line comment, next-line comments.

If the posting's amount is implicit or if elideamount is true, no amount is shown.

If the posting's amount is explicit and multi-commodity, multiple similar postings are shown, one for each commodity, to help produce parseable journal syntax. Or if onelineamounts is true, such amounts are shown on one line, comma-separated (and the output will not be valid journal syntax).

By default, 4 spaces (2 if there's a status flag) are shown between account name and start of amount area, which is typically 12 chars wide and contains a right-aligned amount (so 10-12 visible spaces between account name and amount is typical). When given a list of postings to be aligned with, the whitespace will be increased if needed to match the posting with the longest account name. This is used to align the amounts of a transaction's postings.

Also returns the account width and amount width used.

postingsAsLines :: Bool -> [Posting] -> [Text]

Given a transaction and its postings, render the postings, suitable for print output. Normally this output will be valid journal syntax which hledger can reparse (though it may include no-longer-valid balance assertions).

Explicit amounts are shown, any implicit amounts are not.

Postings with multicommodity explicit amounts are handled as follows: if onelineamounts is true, these amounts are shown on one line, comma-separated, and the output will not be valid journal syntax. Otherwise, they are shown as several similar postings, one per commodity.

The output will appear to be a balanced transaction. Amounts' display precisions, which may have been limited by commodity directives, will be increased if necessary to ensure this.

Posting amounts will be aligned with each other, starting about 4 columns beyond the widest account name (see postingAsLines for details).

showAccountName :: Maybe Int -> PostingType -> AccountName -> Text

Show an account name, clipped to the given width if any, and appropriately bracketed/parenthesised for the given posting type.

renderCommentLines :: Text -> [Text]

Render a transaction or posting's comment as indented, semicolon-prefixed comment lines. The first line (unless empty) will have leading space, subsequent lines will have a larger indent.

misc.

postingTransformAmount :: (MixedAmount -> MixedAmount) -> Posting -> Posting

Apply a transform function to this posting's amount.

postingApplyValuation :: PriceOracle -> Map CommoditySymbol AmountStyle -> Day -> Day -> ValuationType -> Posting -> Posting

Apply a specified valuation to this posting's amount, using the provided price oracle, commodity styles, and reference dates. See amountApplyValuation.

postingToCost :: Map CommoditySymbol AmountStyle -> ConversionOp -> Posting -> Posting

Maybe convert this Postings amount to cost, and apply apply appropriate amount styles.

postingAddInferredEquityPostings :: Text -> Posting -> [Posting]

Generate inferred equity postings from a Posting using transaction prices.

postingPriceDirectivesFromCost :: Posting -> [PriceDirective]
