I've noticed that sometimes when plugin code triggers a runtime error, I
don't get a stack trace. Here's a made-up minimal-ish example:
from beancount.core import amount, data, number
__plugins__ = ("foo",)
def foo(entries, _options):
return [data.Transaction(
flag = "*",
payee = None,
narration = "",
tags = "",
links = set(),
postings = [data.Posting("Equity:Foo",
amount.Amount(number.D("10"), "CAD") + "X", None, None, None, None)]
)], ()
If I run bean-check on a file that imports that plugin, I just get this
output:
falsifian angel beancount $ PYTHONPATH=./plugins bean-check main.beancount
<load>:0: Error importing "foo": can only concatenate tuple (not
"str") to tuple
On the other hand, if I replace the body of foo() with 'raise
BaseException("error")', I get a nice stack trace:
falsifian angel beancount $ PYTHONPATH=./plugins bean-check main.beancount
Traceback (most recent call last):

File
"/home/falsifian/w/colin_and_james/accounting/beancount/plugins/foo.py",
line 4, in foo
raise BaseException("error")
BaseException: error
Why does that happen? Is there a way I can get a stack trace more
consistently? It would help me debug.
