Hledger.Data.Journal

A Journal is a set of transactions, plus optional related data. This is hledger's primary data object. It is usually parsed from a journal file or other data format (see Hledger.Read).

Parsing helpers

addMarketPrice :: MarketPrice -> Journal -> Journal

addTransactionModifier :: TransactionModifier -> Journal -> Journal

addPeriodicTransaction :: PeriodicTransaction -> Journal -> Journal

addTransaction :: Transaction -> Journal -> Journal

journalBalanceTransactions :: Bool -> Journal -> Either String Journal

Fill in any missing amounts and check that all journal transactions balance, or return an error message. This is done after parsing all amounts and applying canonical commodity styles, since balancing depends on display precision. Reports only the first error encountered.

journalApplyCommodityStyles :: Journal -> Journal

Choose and apply a consistent display format to the posting amounts in each commodity. Each commodity's format is specified by a commodity format directive, or otherwise inferred from posting amounts as in hledger < 0.28.

commodityStylesFromAmounts :: [Amount] -> Map CommoditySymbol AmountStyle

Given a list of amounts in parse order, build a map from their commodity names to standard commodity display formats.

journalCommodityStyles :: Journal -> Map CommoditySymbol AmountStyle

Get all the amount styles defined in this journal, either declared by a commodity directive or inferred from amounts, as a map from symbol to style. Styles declared by commodity directives take precedence, and these also are guaranteed to know their decimal point character.

journalConvertAmountsToCost :: Journal -> Journal

Convert all this journal's amounts to cost by applying their prices, if any.

journalFinalise :: ClockTime -> FilePath -> Text -> Bool -> ParsedJournal -> Either String Journal

Do post-parse processing on a parsed journal to make it ready for use. Reverse parsed data to normal order, standardise amount formats, check/ensure that transactions are balanced, and maybe check balance assertions.

journalPivot :: Text -> Journal -> Journal

Apply the pivot transformation to all postings in a journal, replacing their account name by their value for the given field or tag.

Filtering

filterJournalTransactions :: Query -> Journal -> Journal

Keep only transactions matching the query expression.

filterJournalPostings :: Query -> Journal -> Journal

Keep only postings matching the query expression. This can leave unbalanced transactions.

filterJournalAmounts :: Query -> Journal -> Journal

Within each posting's amount, keep only the parts matching the query. This can leave unbalanced transactions.

filterTransactionAmounts :: Query -> Transaction -> Transaction

Filter out all parts of this transaction's amounts which do not match the query. This can leave the transaction unbalanced.

filterTransactionPostings :: Query -> Transaction -> Transaction

filterPostingAmount :: Query -> Posting -> Posting

Filter out all parts of this posting's amount which do not match the query.

Querying

journalAccountNamesUsed :: Journal -> [AccountName]

Sorted unique account names posted to by this journal's transactions.

journalAccountNamesImplied :: Journal -> [AccountName]

Sorted unique account names implied by this journal's transactions - accounts posted to and all their implied parent accounts.

journalAccountNamesDeclared :: Journal -> [AccountName]

Sorted unique account names declared by account directives in this journal.

journalAccountNamesDeclaredOrUsed :: Journal -> [AccountName]

Sorted unique account names declared by account directives or posted to by transactions in this journal.

journalAccountNamesDeclaredOrImplied :: Journal -> [AccountName]

Sorted unique account names declared by account directives, or posted to or implied as parents by transactions in this journal.

journalAccountNames :: Journal -> [AccountName]

Convenience/compatibility alias for journalAccountNamesDeclaredOrImplied.

journalAmounts :: Journal -> [Amount]

Get an ordered list of the amounts in this journal which will influence amount style canonicalisation. These are:

• amounts in market price directives (in parse order)
• amounts in postings (in parse order)

Amounts in default commodity directives also influence canonicalisation, but earlier, as amounts are parsed. Amounts in posting prices are not used for canonicalisation.

overJournalAmounts :: (Amount -> Amount) -> Journal -> Journal

Maps over all of the amounts in the journal

traverseJournalAmounts :: Applicative f => (Amount -> f Amount) -> Journal -> f Journal

Traverses over all ofthe amounts in the journal, in the order indicated by journalAmounts.

journalDateSpan :: Bool -> Journal -> DateSpan

The fully specified date span enclosing the dates (primary or secondary) of all this journal's transactions and postings, or DateSpan Nothing Nothing if there are none.

journalDescriptions :: Journal -> [Text]

Unique transaction descriptions used in this journal.

journalFilePath :: Journal -> FilePath

journalFilePaths :: Journal -> [FilePath]

journalTransactionAt :: Journal -> Integer -> Maybe Transaction

Get the transaction with this index (its 1-based position in the input stream), if any.

journalNextTransaction :: Journal -> Transaction -> Maybe Transaction

Get the transaction that appeared immediately after this one in the input stream, if any.

journalPrevTransaction :: Journal -> Transaction -> Maybe Transaction

Get the transaction that appeared immediately before this one in the input stream, if any.

journalPostings :: Journal -> [Posting]

All postings from this journal's transactions, in order.

Standard account types

journalBalanceSheetAccountQuery :: Journal -> Query

A query for Asset, Liability & Equity accounts in this journal. Cf http://en.wikipedia.org/wiki/Chart_of_accounts#Balance_Sheet_Accounts.

journalProfitAndLossAccountQuery :: Journal -> Query

A query for Profit & Loss accounts in this journal. Cf http://en.wikipedia.org/wiki/Chart_of_accounts#Profit_.26_Loss_accounts.

journalIncomeAccountQuery :: Journal -> Query

A query for Income (Revenue) accounts in this journal. This is currently hard-coded to the case-insensitive regex ^(income|revenue)s?(:|$).

journalExpenseAccountQuery :: Journal -> Query

A query for Expense accounts in this journal. This is currently hard-coded to the case-insensitive regex ^expenses?(:|$).

journalAssetAccountQuery :: Journal -> Query

A query for Asset accounts in this journal. This is currently hard-coded to the case-insensitive regex ^assets?(:|$).

journalLiabilityAccountQuery :: Journal -> Query

A query for Liability accounts in this journal. This is currently hard-coded to the case-insensitive regex ^(debts?|liabilit(y|ies))(:|$).

journalEquityAccountQuery :: Journal -> Query

A query for Equity accounts in this journal. This is currently hard-coded to the case-insensitive regex ^equity(:|$).

journalCashAccountQuery :: Journal -> Query

A query for Cash (-equivalent) accounts in this journal (ie, accounts which appear on the cashflow statement.) This is currently hard-coded to be all the Asset accounts except for those containing the case-insensitive regex (receivable|:A/R|:fixed).

Misc

canonicalStyleFrom :: [AmountStyle] -> AmountStyle

Given an ordered list of amount styles, choose a canonical style. That is: the style of the first, and the maximum precision of all.

matchpats :: [String] -> String -> Bool

Check if a set of hledger account/description filter patterns matches the given account name or entry description. Patterns are case-insensitive regular expressions. Prefixed with not:, they become anti-patterns.

nulljournal :: Journal

journalCheckBalanceAssertions :: Journal -> Either String Journal

Check any balance assertions in the journal and return an error message if any of them fail.

journalNumberAndTieTransactions :: Journal -> Journal

journalUntieTransactions :: Transaction -> Transaction

Untie all transaction-posting knots in this journal, so that eg recursiveSize and GHCI's :sprint can work on it.
