Many Python binding methods silently returned raw SwigPyObject pointers
instead of proper Python wrapper objects because the methods_return_instance
dicts were incomplete. This adds the missing entries and activates the
DeprecationWarning in the SWIG typemap fallback path from PR 1.
Return-type wrapping fixes (gnucash_core.py):
GncPrice (new dict — no wrapping existed before):
get_commodity → GncCommodity, get_currency → GncCommodity,
clone → GncPrice, get_value → GncNumeric
GncPriceDB (added to existing dict):
nth_price → GncPrice, lookup_day_t64 → GncPrice,
convert_balance_nearest_before_price_t64 → GncNumeric
GncPriceDB (new list wrapping):
lookup_latest_any_currency → list[GncPrice],
lookup_nearest_before_any_currency_t64 → list[GncPrice],
lookup_nearest_in_time_any_currency_t64 → list[GncPrice]
GncCommodity: obtain_twin → GncCommodity,
get_namespace_ds → GncCommodityNamespace
Account: get_currency_or_parent → GncCommodity,
GetLotList → list[GncLot]
GncLot: get_split_list → list[Split]
Example script cleanup:
Remove type(x).__name__ == 'SwigPyObject' workarounds from
gnc_convenience.py, gncinvoicefkt.py, str_methods.py — these are
no longer needed now that methods return proper wrapper objects.
SWIG typemap (gnucash_core.i):
Activate DeprecationWarning on the .instance fallback path, replacing
the TODO placeholder from the typemap compatibility layer commit.
New test file (test_price_and_wrapping.py):
18 tests covering all wrapping fixes and typemap compatibility,
using in-repo test data (pricedb1.gml2, sample1.gnucash).
Tests auto-skip when XML backend is unavailable.
