-- | An account transactions report represents transactions affecting
|

-- a particular account (or possibly several accounts, but we don't
|
|
-- use that). It is used eg by hledger-ui's and hledger-web's register
|
|
-- view, and hledger's aregister report, where we want to show one row
|
|
-- per transaction, in the context of the current account. Report
|
|
-- items consist of:
|
|
--
|
|
-- - the transaction, unmodified
|
|
--
|
|
-- - the transaction as seen in the context of the current account and query,
|
|
-- which means:
|
|
--
|
|
-- - the transaction date is set to the "transaction context date":
|
|
-- the earliest of the transaction date and any other posting dates
|
|
-- of postings to the current account (matched by the report query).
|
|
--
|
|
-- - the transaction's postings are filtered, excluding any which are not
|
|
-- matched by the report query
|
|
--
|
|
-- - a text description of the other account(s) posted to/from
|
|
--
|
|
-- - a flag indicating whether there's more than one other account involved
|
|
--
|
|
-- - the total increase/decrease to the current account
|
|
--
|
|
-- - the report transactions' running total after this transaction;
|
|
-- or if historical balance is requested (-H), the historical running total.
|
|
-- The historical running total includes transactions from before the
|
|
-- report start date if one is specified, filtered by the report query.

-- The historical running total may or may not be the account's historical
|
