Examples
==========
Create a DateTimeRange instance from start and end datetime
-----------------------------------------------------------------
:Sample Code:
    .. code:: python

        from datetimerange import DateTimeRange
        time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
        str(time_range)

:Output:
    ::

        '2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900'

Create a DateTimeRange instance from a range text
-----------------------------------------------------------------
:Sample Code:
    .. code:: python

        from datetimerange import DateTimeRange
        time_range = DateTimeRange.from_range_text("2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900")
        str(time_range)

:Output:
    ::

        '2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900'

Get an iterator
------------------------
:Sample Code 1:
    .. code:: python

        import datetime
        from datetimerange import DateTimeRange

        time_range = DateTimeRange("2015-01-01T00:00:00+0900", "2015-01-04T00:00:00+0900")
        for value in time_range.range(datetime.timedelta(days=1)):
            print(value)

:Output 1:
    ::

        2015-01-01 00:00:00+09:00

        2015-01-03 00:00:00+09:00
        2015-01-04 00:00:00+09:00

:Sample Code 2:
    .. code:: python

        from datetimerange import DateTimeRange
        from dateutil.relativedelta import relativedelta

        time_range = DateTimeRange("2015-01-01T00:00:00+0900", "2016-01-01T00:00:00+0900")
        for value in time_range.range(relativedelta(months=+4)):
            print(value)

:Output 2:
    ::

        2015-01-01 00:00:00+09:00
        2015-05-01 00:00:00+09:00
        2015-09-01 00:00:00+09:00
        2016-01-01 00:00:00+09:00

Test whether a value within the time range
------------------------------------------
:Sample Code:
    .. code:: python

        from datetimerange import DateTimeRange

        time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
        print("2015-03-22T10:05:00+0900" in time_range)
        print("2015-03-22T10:15:00+0900" in time_range)

        time_range_smaller = DateTimeRange("2015-03-22T10:03:00+0900", "2015-03-22T10:07:00+0900")
        print(time_range_smaller in time_range)

:Output:
    ::

        True
        False
        True

Test whether a value intersects the time range
----------------------------------------------
:Sample Code:
    .. code:: python

        from datetimerange import DateTimeRange
        time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
        x = DateTimeRange("2015-03-22T10:05:00+0900", "2015-03-22T10:15:00+0900")
        time_range.is_intersection(x)

:Output:
    ::

        True

Make an intersected time range
------------------------------
:Sample Code:
    .. code:: python

        from datetimerange import DateTimeRange
        time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
        x = DateTimeRange("2015-03-22T10:05:00+0900", "2015-03-22T10:15:00+0900")
        time_range.intersection(x)

:Output:
    ::

        2015-03-22T10:05:00+0900 - 2015-03-22T10:10:00+0900

Make an encompassed time range
------------------------------
:Sample Code:
    .. code:: python

        from datetimerange import DateTimeRange
        time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
        x = DateTimeRange("2015-03-22T10:05:00+0900", "2015-03-22T10:15:00+0900")
        time_range.encompass(x)

:Output:
    ::

        2015-03-22T10:00:00+0900 - 2015-03-22T10:15:00+0900

Truncate time range
-------------------
:Sample Code:
    .. code:: python

        from datetimerange import DateTimeRange

        time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
        time_range.is_output_elapse = True
        print("before truncate: ", time_range)

        time_range.truncate(10)
        print("after truncate:  ", time_range)

:Output:
    ::

        before truncate:  2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900 (0:10:00)
        after truncate:   2015-03-22T10:00:30+0900 - 2015-03-22T10:09:30+0900 (0:09:00)
