Is it possible to add more supported language

[cyanxiao]

I'm recently working on a non-Latin language to CLNST library. Once it's finished, I decide to submit a PR to add more language support to retext. However, I'm not sure whether retext is currently constrained to Dutch / English / Latin and no more new languages are allowed.

Yeah, it is possible. It is somewhat difficult though.
See parse-dutch and parse-english, which add a couple of rules on top of parse-latin. You could create something based on parse-latin as well, if you’re say, dealing with French. For languages using other scripts, it’s going to get tougher.
For retext, which includes many wordlist based rules, you’d need to translate those wordlists!

Thank you! Actually I'm implementing Chinese & Japanese to CLNST so it may not base on parse-latin and use other techniques instead. I hope I can overcome the difficulties 🥲
