Hey Folks,

When I do a ledger.read_journal in python on a file with virtual postings,
has_flag(POST_VIRTUAL) returns False. I would expect it to return True.
Here's a bash run with the details:

$ ledger --version
Ledger 3.2.1-20200518, the command-line accounting tool

$ cat journal.dat
2022-7-24 August 2022 Budget
[Budget:Expenses:Gas] $200.00
[Budget:Equity] -$200.00

$ cat virtual_posts.py
import ledger

for xact in ledger.read_journal("journal.dat"):
print(repr(xact))
for post in xact.posts():
is_virtual = post.xdata().has_flags(ledger.POST_VIRTUAL)
must_balance = post.xdata().has_flags(ledger.POST_MUST_BALANCE)
print("%r is virtual: %s, must balance: %s" % (post, is_virtual, must_balance))

$ python3 virtual_posts.py journal.dat
<ledger.Transaction object at 0x7f588b011040>
<ledger.Posting object at 0x7f588b0110a0> is virtual: False, must balance: False
<ledger.Posting object at 0x7f588b011100> is virtual: False, must balance: False


Can anyone spot any issues with what I'm doing? If not, should I file a
bug against ledger?

Thanks!

Thanks for reaching out, Ryan,

at first glance this seems to be a valid issue as
`post.xdata().has_flags(ledger.POST_MUST_BALANCE)` returns `False`
when `post.must_balance()` returns `True`.
Using `post.must_balance()` might be a viable interim solution.

Unfortunately there is no `is_virtual()` function on the `Posting`
type and the exposed `has_flags` fails with the following error for me:

```
did not match C++ signature:
has_flags(supports_flags<unsigned char, unsigned char> {lvalue}, unsigned char)
```

It would be greatly appreciated if you could file a bug against
ledger for this.


Best
Alexis
