See docstring for full rationale. This greatly reduces the need for other
plugin code to handle the case of `post.units.number is None`, eliminating
the need for entire methods and letting it do plain numeric comparisons.
This lets us import the plugin module without importing all of the included
hooks. This provides better isolation and error reporting in case there's
something like a syntax problem in one of the hooks: it doesn't cause
importing any plugin module to fail.
Extend the base class from checking 1 metadata value to checking N.
This is preparation for RT#10643, letting payables be documented with
invoice or contract.
This does unify error reporting, because now we always report all
type/invalid value errors *plus* a missing error if appropriate.
I think this consistency and thoroughness is appropriate, although
it did require some adjustments to the tests.
Python 3.6 does not implement __class_getitem__, and because of that
it's not possible to introspect when things like Hook[Transaction]
are called. Sidestep the issue with a more explicit assignment.
When we send checks, we don't have a check document anywhere (for
security reasons), we just note the check number. Update the
validation to match. RT#10507.
The main impetus of this change is to rename accounts that were outside
Beancount's accepted five root accounts, to move them into that
structure. This includes:
Accrued:*Payable: → Liabilities:Payable:*
Accrued:*Receivable: → Assets:Receivable:*
UneanedIncome:* → Liabilities:UnearnedIncome:*
Note the last change did inspire in a change to our validation rules. We no
longer require income-type on unearned income, because it's no longer
considered income at all. Once it's earned and converted to an Income
account, that has an income-type of course.
This did inspire another rename that was not required, but
provided more consistency with the other account names above:
Assets:Prepaid* → Assets:Prepaid:*
Where applicable, I have generally extended tests to make sure one of each
of the five account types is tested. (This mostly meant adding an Equity
account to the tests.) I also added tests for key parts of the hierarchy,
like Assets:Receivable and Liabilities:Payable, where applicable.
As part of this change, Account.is_real_asset() got renamed to
Account.is_cash_equivalent(), to better self-document its purpose.
Because these are the classes that get instantiated many times while
iterating transactions, the performance benefit of defining __slots__
is worth the development overhead.
The main motivation for this change is to make sure that higher-level
code deals with the fact that self.units.number can be None, and has
an easy way to do so.
I'm not sure all our code is *currently* doing the right thing for this
case, because I'm not sure it will ever actually come up. It's possible
that earlier Beancount plugins fill in decimal amounts for postings
that are originally loaded with self.units.number=None. I'll have to see
later whether this case comes up in reality, and then deal with it if so.
For now the safest strategy seems to be that most code should operate
when self.units.number is None.
I'm getting to ready to extend this hook to deal with income receipts as
well as expense receipts. These changes let me write the tests in a more
declarative style, so I don't have to duplicate them all again to test
credits as well as debits.
Note that we're only testing debits right now, just like the existing tests,
because the default check_type for check() is PostType.DEBIT. Part of making
the changes will be changing that to PostType.BOTH.
