Empty values (handling None type)

[itepifanio]

Toml files can be written without values example:

user="support@company.com"
password=

This empty values could be translated to/from None. So I would expect something like:

import tomli_w

doc = {"table": {"nested": {}, "val3": 3}, "val2": 2, "val1": None}
expected_toml = """\
val2 = 2
val1 =

[table]
val3 = 3

[table.nested]
"""
assert tomli_w.dumps(doc) == expected_toml

to work, but it's not the case.

Thanks for the issue, but TOML does not have null values so this will not be accepted. Tomli-W should not dump invalid TOML.
