How can I compare two deferred expressions?

[snowch]

My application uses a limited set of ibis expressions that users can define using yaml which is parsed into deferred's.

I'm trying to test as follows:

def test_datestring():
    yaml_predicate = """
    and:
    - column: tpep_pickup_datetime
      op: ">="
      value: "20120101"
    - column: tpep_pickup_datetime
      op: "<="
      value: "20120110"
    """
    actual = parse_yaml_predicate(yaml_predicate).compile()
    expected = ((_["tpep_pickup_datetime"] >= "20120101") & (_["tpep_pickup_datetime"] <= "20120110")).compile()

    assert repr(actual) == repr(expected)

however, I'm hitting the following issue:

>       assert repr(actual) == repr(expected)
E       AssertionError: assert '<ibis.expr.d... 0x103a88fa0>' == '<ibis.expr.d... 0x103be34f0>'
E         
E         Skipping 34 identical leading characters in diff, use -v to show
E         - t at 0x103be34f0>
E         ?           ^^^^
E         + t at 0x103a88fa0>
E         ?           ^^^ +

I've also tried using str():

        ibis_expr = parse_yaml_predicate(yaml_predicate)
>       assert str(ibis_expr) == "(_['vendor_id'] == 3)"
E       assert '<ibis.expr.d... 0x107eaedc0>' == "(_['vendor_id'] == 3)"
E         
E         - (_['vendor_id'] == 3)
E         + <ibis.expr.deferred.Deferred object at 0x107eaedc0>

I'm using ibis-framework==9.0.0

Any ideas?

I think you're looking for exprA.equals(exprB)? see #8754 (comment)
