class auto_flex

Bases: object

Configuration for the ‘auto’ Flex logic.

This class determines how (lo, hi)-tuples are expanded when flexible bounds are enabled.

SANITY_CHECK: bool = True

If True, use original limits if flexed limits do not pass sanity checks.

classmethod set_level(level: Literal['hour', 'day'], *, start_at: str | Timedelta | timedelta | timedelta64, round_to: str | Timedelta | timedelta | timedelta64, tolerance: str | Timedelta | timedelta | timedelta64) → None

Set a Level used by the auto-flex logic.

Inputs are not verified until an actual split is made.

Parameters:

• level – The level to set; ‘hour’ or ‘day’.

• start_at – Span size at which this level starts.

• round_to – Frequency to round the range limits to.

• tolerance – Maximum amount by which to alter limits.

Raises:

AttributeError – For unknown level names.

class Level(start_at: str | Timedelta | timedelta | timedelta64, round_to: str | Timedelta | timedelta | timedelta64, tolerance: str | Timedelta | timedelta | timedelta64)

Bases: NamedTuple

Level type used by auto_flex.

start_at: str | Timedelta | timedelta | timedelta64

Span size at which this level starts.

round_to: str | Timedelta | timedelta | timedelta64

Frequency to round the range limits to.

tolerance: str | Timedelta | timedelta | timedelta64

Maximum amount by which to alter limits.

hour: Level = Level(start_at='6 hours', round_to='hour', tolerance='15 min')

Conditions under which bounds are rounded to the nearest hour.

Default setting:

Round to hour if the total range is at least 6 hours, but do not move the bounds more than 15 minutes.

day: Level = Level(start_at='2 days', round_to='day', tolerance='3 hours')

Conditions under which bounds are rounded to the nearest day.

Default setting:

Round to day if the total range is at least 2 days, but do not move the bounds more than 3 hours.

class plot

Bases: object

Global settings for the plot()-function.

THOUSANDS_SEPARATOR: str = "'"

Sign to use when printing bar_labels.

THOUSANDS_SEPARATOR_CUTOFF: int = 10000

Minimum value before bar_labels include a THOUSANDS_SEPARATOR.

ROW_UNIT: str = 'rows'

Unit to append to the count when displaying number of rows on the bars.

DATA_LABEL: str = 'Data'

Label of the blue bar.

FUTURE_DATA_LABEL: str = 'Future data'

Label of the red bar.

DEFAULT_TIME_UNIT: str = 'h'

Time unit to use by default when bar_labels=True and available=None.

class log_split_progress

Bases: object

Global settings for the log_split_progress()-function.

FOLD_FORMAT: str = "('{start.auto}' <= [schedule: '{mid.auto}' ({mid:%A})] < '{end.auto}')"

Pretty-printed fold-key for other messages.

• Only the start, mid, and end keys are available (see DatetimeSplitBounds). You may use <key>.auto to format as a date when time is zero (this is the default).

Sample output.

('2021-12-30' <= [schedule: '2022-01-04' (Tuesday)] < '2022-01-04 18:00:00')

SECONDS_FORMATTER: str | Callable[[float], str] = 'rics.performance.format_seconds'

A callable (seconds) -> formatted_seconds.

Both seconds and formatted_seconds will be available to the END_MESSAGE message. If a string is given, the actual callable will be resolved using rics.misc.get_by_full_name().

START_MESSAGE: str = 'Begin fold {n}/{n_splits}: {fold}.'

Message indicating that the current fold has been yielded to the user.

Has access to all keys from the previous section, as well as:

• The fold key (see FOLD_FORMAT), and

• The n key, which is the 1-based position of the fold in splits, and

• The n_folds key, which is just len(splits).

Sample output.

 Begin fold 5/7: ('2021-12-30' <= [schedule: '2022-01-04' (Tuesday)] < '2022-01-04 18:00:00').

END_MESSAGE: str = "Finished fold {n}/{n_splits} [schedule: '{mid.auto}' ({mid:%A})] after {formatted_seconds}."

Message indicating that the user is done with the current fold.

Has access to all keys from the previous sections, as well as:

• The seconds key, which is the (fractional) time the user spent in the fold, and

• The formatted_seconds key, obtained using the SECONDS_FORMATTER.

The value of seconds is obtained using time.perf_counter().

Sample output.

 Finished fold 5/7 [schedule: '2022-01-04' (Tuesday)] after 5m 21s.

AUTO_DATE_FORMAT = '%Y-%m-%d'

Short-form timestamp format_spec used by <key>.auto.

AUTO_DATETIME_FORMAT = '%Y-%m-%d %H:%M:%S'

Long-form timestamp format_spec used by <key>.auto.
