Changelog

0.2.0 (unreleased)

Same word lists and matching rules as the JavaScript package 0.2.0.

Many more English words, including slurs (fag, faggot, nigger…) and compounds (shitface, dipshit, jackass…), and more Romanized and Devanagari Nepali words (jhant, lauda, chhinal, gadha, ullu…).
New English words at the strict level that are also ordinary words: damn, cum, prick, hoe and others.
shit is now a stem, so shitface and shitting are caught. Names that start with it, like Shitij and Shital, are on the allow list.
A built-in allow list of names and ordinary words, like Randip, Shitij, conditions and Scunthorpe, that are never flagged. The strict level no longer flags them.
A few roots, like fuck and bitch, are caught inside a longer word: dumbfuck, sonofabitch.
x is read as chh in Romanized Nepali, so xakka matches chhakka. chhod ("leave") and chhodnu are no longer flagged by the stem chod.
Words split by punctuation without a space are read joined: sh.it, fu-ck.
Accents and Cyrillic or Greek look-alike letters are removed or replaced: fück, fuсk. 8 reads as b, 9 as g and € as e.
extra_words option to flag more words, and allow_words option to never flag a word.
