Hi All
I'm working through balance-sheet.scm and overhauling this report.
At the same time, I can see that balance-sheet.scm and
income-statement.scm can be merged together.
After all
* balance sheet = asset/liability/equity balance at date X,
* income statement = difference in income/expense balances at date X and Y
The issue I have is that the balance sheet can call
xaccAccountGetBalanceAsOfDate(acc,date) directly to nicely retrieve the
balance, whereas income statement cannot directly call it because it
also includes closing transactions.
My proposal is to augment xaccAccountGetBalanceAsOfDate to accept a 3rd
boolean argument i.e.
xaccAccountGetBalanceAsOfDate(acc,date,ignoreclosing) which will
selectively produce the balance, ignore closing transactions.
This is partly done in the last commit of
https://github.com/christopherlam/gnucash/tree/maint-create-API-call-for-noclosing-balances
- it will augment API everywhere, and also modify Account.cpp,
especially xaccAccountRecomputeBalance which will call
xaccTransGetIsClosingTxn(xaccSplitGetParent(split)) for each split in
the account to determine closing status and cache the balances for each
split. See draft on
https://github.com/christopherlam/gnucash/tree/maint-create-API-call-for-noclosing-balances
- this currently fails because I'm not good at C.
*My query is whether it will be too expensive to call
xaccTransGetIsClosingTxn for each split in Account.cpp to produce the
split->noclosing_balance, which will be crucial to calculate income
between two dates.*
*Currently this 'closing-txn' filter is done in income-statement.scm via
a "Closing Entries" string/regex filter and xaccTransGetIsClosingTxn
calls, which IMHO is not ideal either.
*
Any help welcome!
P.S. if this last commit is removed, the
https://github.com/christopherlam/gnucash/tree/maint-create-API-call-for-noclosing-balances
branch contains work-so-far for updated balance-sheet. Screenshot

multilevel subtotals were previously horizonal, are now vertical;
original-currency amounts, and multiple-date balance sheets.
