feruca 0.1.1

Python bindings for feruca, a Rust implementation of the Unicode Collation Algorithm

feruca-py

This package is meant to provide a basic Python interface to feruca, a Rust implementation of the Unicode Collation Algorithm. There is, at this point, only one function available: collate, which sorts a list of strings in accordance with the UCA, and with a choice of a few "tailorings."

There is a strong possibility that the Python API will be changed, depending on user feedback, benchmarking results, etc. This initial version is essentially a proof of concept.

Below is an example of how to use the collate function in its current form:

from feruca import collate

strings = ["zebra", "éléonore", "grok"]

# Tailoring options are "default", "ArabicScript", and "ArabicInterleaved"
strings_sorted = collate(strings, tailoring="default")

print(strings_sorted) # ['éléonore', 'grok', 'zebra']

The default tailoring follows the "root collation order" defined by the Common Locale Data Repository (CLDR). ArabicScript modifies this such that the Arabic script as a whole sorts before the Latin script. ArabicInterleaved is more nuanced, mixing the two scripts such that Arabic alif sorts after A but before B; bā’ sorts after B but before C; etc.

In all cases, the "shifted" approach is taken with variable-weight characters. A number of such options that are configurable in the Rust library are not yet exposed in this Python wrapper.
