As new translation entries will be far and few between (due to the simplicity of the app), most people will just be improving the wording of certain existing entries or adding whole languages.
Modify the source code, and anywhere where you need a translated string, use the tr!
macro.
Then, install xtr
with cargo install xtr
and run:
xtr src/main.rs -o po/hello-rhino.pot
Add your language code to po/LINGUAS
, and then run:
cp po/hello-rhino.pot po/<LANG>.po
And then you can work on that file.
