# coding: utf-8 """ http://yaml.org/type/timestamp.html specifies the regexp to use for datetime.date and datetime.datetime construction. Date is simple but datetime can have 'T' or 't' as well as 'Z' or a timezone offset (in hours and minutes). This information was originally used to create a UTC datetime and then discarded examples from the above: canonical: 2001-12-15T02:59:43.1Z valid iso8601: 2001-12-14t21:59:43.10-05:00 space separated: 2001-12-14 21:59:43.10 -5 no time zone (Z): 2001-12-15 2:59:43.10 date (00:00:00Z): 2002-12-14 Please note that a fraction can only be included if not equal to 0 """ import sys import copy import pytest # type: ignore # NOQA from datetime import datetime as DateTime, timezone as TimeZone, timedelta as TimeDelta from roundtrip import round_trip, dedent, round_trip_load, round_trip_dump # type: ignore # NOQA class TestDateTime: def test_date_only(self) -> None: inp = """ - 2011-10-02 """ exp = """ - 2011-10-02 """ round_trip(inp, exp) def test_zero_fraction(self) -> None: inp = """ - 2011-10-02 16:45:00.0 """ exp = """ - 2011-10-02 16:45:00 """ round_trip(inp, exp) def test_long_fraction(self) -> None: inp = """ - 2011-10-02 16:45:00.1234 # expand with zeros - 2011-10-02 16:45:00.123456 - 2011-10-02 16:45:00.12345612 # round to microseconds - 2011-10-02 16:45:00.1234565 # round up - 2011-10-02 16:45:00.12345678 # round up """ exp = """ - 2011-10-02 16:45:00.123400 # expand with zeros - 2011-10-02 16:45:00.123456 - 2011-10-02 16:45:00.123456 # round to microseconds - 2011-10-02 16:45:00.123457 # round up - 2011-10-02 16:45:00.123457 # round up """ round_trip(inp, exp) def test_canonical(self) -> None: inp = """ - 2011-10-02T16:45:00.1Z """ exp = """ - 2011-10-02T16:45:00.100000Z """ round_trip(inp, exp) def test_spaced_timezone(self) -> None: inp = """ - 2011-10-02T11:45:00 -5 """ exp = """ - 2011-10-02T11:45:00-5 """ round_trip(inp, exp) def test_normal_timezone(self) -> None: round_trip(""" - 2011-10-02T11:45:00-5 - 2011-10-02 11:45:00-5 - 2011-10-02T11:45:00-05:00 - 2011-10-02 11:45:00-05:00 """) def test_no_timezone(self) -> None: inp = """ - 2011-10-02 6:45:00 """ exp = """ - 2011-10-02 06:45:00 """ round_trip(inp, exp) def test_explicit_T(self) -> None: inp = """ - 2011-10-02T16:45:00 """ exp = """ - 2011-10-02T16:45:00 """ round_trip(inp, exp) def test_explicit_t(self) -> None: # to upper inp = """ - 2011-10-02t16:45:00 """ exp = """ - 2011-10-02T16:45:00 """ round_trip(inp, exp) def test_no_T_multi_space(self) -> None: inp = """ - 2011-10-02 16:45:00 """ exp = """ - 2011-10-02 16:45:00 """ round_trip(inp, exp) def test_iso(self) -> None: round_trip(""" - 2011-10-02T15:45:00+01:00 """) def test_zero_tz(self) -> None: round_trip(""" - 2011-10-02T15:45:00+0 """) def test_issue_45(self) -> None: round_trip(""" dt: 2016-08-19T22:45:47Z """) def test_issue_366(self) -> None: import ruamel.yaml import io round_trip(""" [2021-02-01 22:34:48.696868-03:00] """) yaml = ruamel.yaml.YAML() dd = DateTime(2021, 2, 1, 22, 34, 48, 696868, TimeZone(TimeDelta(hours=-3), name='')) buf = io.StringIO() yaml.dump(dd, buf) assert buf.getvalue() == '2021-02-01 22:34:48.696868-03:00\n...\n' rd = yaml.load(buf.getvalue()) assert rd == dd def test_deepcopy_datestring(self) -> None: # reported by Quuxplusone, http://stackoverflow.com/a/41577841/1307905 x = dedent("""\ foo: 2016-10-12T12:34:56 """) data = copy.deepcopy(round_trip_load(x)) assert round_trip_dump(data) == x def test_fraction_overflow(self) -> None: # reported (indirectly) by Luís Ferreira # https://sourceforge.net/p/ruamel-yaml/tickets/414/ inp = dedent("""\ - 2022-01-02T12:34:59.9999994 - 2022-01-02T12:34:59.9999995 """) exp = dedent("""\ - 2022-01-02T12:34:59.999999 - 2022-01-02T12:35:00 """) round_trip(inp, exp) def Xtest_tzinfo(self) -> None: import ruamel.yaml yaml = ruamel.yaml.YAML() dts = '2011-10-02T16:45:00.930619+01:00' d = yaml.load(dts) print('d', repr(d), d._yaml) yaml.dump(dict(x=d), sys.stdout) print('----') # dx = DateTime.fromisoformat(dts) # print('dx', dx, repr(dx)) dd = DateTime(2011, 10, 2, 16, 45, 00, 930619, TimeZone(TimeDelta(hours=1, minutes=0), name='+01:00')) # NOQA yaml.dump([dd], sys.stdout) print('dd', dd, dd.tzinfo) raise AssertionError()
