This module will sort text in the Kana script.
The module should preferably not be called directly from templates or other modules.
To use it from a template, use {{sortkey}}.
Within a module, use Module:languages#Language:makeSortKey.
For testcases, see Module:Hrkt-sortkey/testcases.
Functions
makeSortKey(text, lang, sc)- Generates a sortkey for a given piece of
textwritten in the script specified by the codesc, and language specified by the codelang. - When the sort fails, returns
nil.
local m_ja = require("Module:ja")
local kata_to_hira = m_ja.kata_to_hira
local normalize_kana = m_ja.normalize_kana
local umatch = mw.ustring.match
local data = mw.loadData("Module:Hrkt-sortkey/data")
local export = {}
-- Generate a sortkey from a kana input. This can be any combination of hiragana and katakana, and will not be normalized to hiragana or katakana first. Use [[Module:Hira-sortkey]] or [[Module:Kana-sortkey]] if that is required, which in turn call this module.
function export.makeSortKey(text, lang, sc)
-- Normalize long vowel and iteration marks.
text = normalize_kana(text)
-- Middle dots and double hyphens (including fullwidth equals signs) become spaces, unless that results in the output becoming all whitespace.

-- For each dakuten and handakuten, remove it and add 1 or 2 apostrophes to the end (respectively).
