Data package:hledger-lib

The Hledger.Data library allows parsing and querying of C++ ledger-style journal files. It generally provides a compatible subset of C++ ledger's functionality. This package re-exports all the Hledger.Data.* modules (except UTF8, which requires an explicit import.)

Given a rules file path, what would be the corresponding data file ? (Remove a .rules extension.)

Data that's useful in "balance" reports: subaccount-exclusive and -inclusive amounts, typically representing either a balance change or an end balance; and a count of postings.

Data values for zero or more report periods, and for the pre-report period. Report periods are assumed to be contiguous, and represented only by start dates (as keys of an IntMap). XXX how does that work, again ?

associated data per report period

Convert a list of DateSpans to a 'PeriodData Day', or Nothing if it is not well-formed. PARTIAL:

Add account balance information to the appropriate location in PeriodData.

Get account balance information for the period containing a given Day, along with the start of the period, or Nothing if this day lies in the historical period.

Get account balance information for the period containing a given Day or the historical data if this day lies in the historical period, along with the start of the period or Nothing if it lies in the historical period.

Apply an operation to both MixedAmount in an BalanceData.

Merges two PeriodData, using the given operations for balance information only in the first, only in the second, or in both PeriodData, respectively.

Merge two BalanceData, using the given operation to combine their amounts.

Merges two PeriodData, using the given operation to combine their balance information. This will drop keys if they are not present in both PeriodData.

Pad out the datemap of a PeriodData so that every key from another PeriodData is present.

Construct an PeriodData from a list.

Convert 'PeriodData Day' to a list of DateSpans.

Convert PeriodData to a list of pairs.

Apply a function to all PeriodData within this and sub accounts.

Custom error data for hledger parsers. Specialised for a Text parse stream. ReparseableTextParseErrorData ?
