Re: Internationalization of Lua Programs

[Yuri Takhteyev <yuri@...>]

Sputnik uses this rather simple module:

https://github.com/yuri/sputnik/blob/master/sputnik/lua/sputnik/i18n.lua

It really just relies on looking up translations in a table, but it
adds system for fallback locales (where you can say that pt_PT is
fallback for pt_BR and en_US is the fallback for pt_BR).

Also, there is this module that looks quite promising.

https://github.com/kikito/i18n.lua/

It's quite a bit more involved and supports pluralization, including
for languages with tricky rules (like different forms of plural for
small and large numbers).
