Indexing within indicators

HISTORY.rst

@@ -10,17 +10,18 @@ New features and enhancements
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 * Added an optimized pathway for ``xclim.indices.run_length`` functions when ``window=1``. (:pull:`911`, :issue:`910`).
 * The data input frequency expected by ``Indicator``s is now in the ``src_freq`` attribute and is thus controllable by subclassing existing indicators. (:issue:`898`, :pull:`927`).
+* New ``**indexer`` keyword args added to many indicators, it accepts the same arguments as ``xclim.indices.generic.select_time``, which has been improved. Unless otherwise specified, the time selection is done before any computation. (:pull:`934`, :issue:`899`).
 
 Breaking changes
-~~~~~~~~~~~~~~~~
+^^^^^^^^^^^^^^^^
 * Following version 1.9 of the CF Conventions, published in September 2021, the calendar name "gregorian" is deprecated. ``core.calendar.get_calendar`` will return "standard", even if the underlying cftime objects still use "gregorian" (cftime <= 1.5.1). (:pull:`935`).
 
 Internal changes
 ^^^^^^^^^^^^^^^^
 * Removed some logging configurations in ``dataflags`` that were polluting python's main logging configuration. (:pull:`909`).
 * Synchronized logging formatters in `xclim.ensembles` and `xclim.core.utils`. (:pull:`909`).
 * Added a helper function for generating the release notes with dynamically-generated ReStructuredText or Markdown-formatted hyperlinks (:pull:`922`, :issue:`907`).
-* Split of resampling-related functionality of ``Indicator``s into a new ``ResamplingIndicator`` subclass. The use of new (private) methods makes it easier to inject functionality in indicator subclasses. (:issue:`867`, :pull:`927`).
+* Split of resampling-related functionality of ``Indicator``s into a new ``ResamplingIndicator`` and ``ResamplingIndicatorWithIndexing`` subclasses. The use of new (private) methods makes it easier to inject functionality in indicator subclasses. (:issue:`867`, :pull:`927`, :pull:`934`).
 * French translation metadata fields are now cleaner and much more internally consistent, and many empty metadata fields (e.g. ``comment_fr``) have been removed. (:pull:`930`, :issue:`929`).
