Gramps plugin Topola can support any language now.
For add/change your language you must add/change you language’s words in 2 files:
- https://github.com/PeWu/topola/blob/master/src/date-format.ts
-
https://github.com/PeWu/topola-viewer/blob/master/src/index.tsx
and add/change language file on this dir: - https://github.com/PeWu/topola-viewer/tree/master/src/translations
(fork this two repos and PR after your add/change).
