Refactor i18n to use ICU and sentences - #457
Conversation
|
Hi @krokosik , if I remove or add keys, will it be a problem to update on Weblate? |
|
My experience is that removing keys breaks stuff, but adding is fine. Also try to add them not in the last line (to eliminate JSON comma diffs 🤢) |
|
Hi @marcosinigaglia, any updates on this? I do the French translations for Splitpro and I know this will be a problem too (even if we didn't finish the v2.x upgrade with french translations on our server yet). |
|
Hi @FelixDz , I don't have much free time right now, but I'll get back to it as soon as I can. If you want to pick up where I left off or start a new PR, feel free to go ahead. |

Thanks for using CodeRabbit! It's free for OSS, and your support helps us grow. If you like it, consider giving us a shout-out. Comment |
- add English and Italian ICU translation catalogs - replace fragmented translations with contextual messages - support locale variants with normalized fallback resolution - translate remaining UI text and notifications
- add missing split validation and debt direction translations - restore ICU pluralization for participant counts - handle negative expense debt direction correctly - add a parameterless sign-in failure message

Hi @krokosik , I think the PR is in good shape; if the changes made are okay, I'll remove the old translation files. I created completely new files to avoid issues with Weblate. For now, there are only files for Italian and English; the most I can do is have the AI translate them into the languages that were there before, or we can have the translations redone. |

In `@public/locales/it/common_icu.json`:
- Around line 8-11: Remove the direct Italian feature translations from
public/locales/it/common_icu.json lines 8-11 and public/locales/it/home_icu.json
lines 7-10, leaving new feature keys in English for Weblate to translate. Do not
modify these sites unless an approved translation-workflow exception is
confirmed.
- Line 452: Update the days_of_week translation value to the complete Italian
label “Giorni della settimana”, replacing the incomplete text while preserving
the existing localization key and JSON structure.
In `@src/components/Friend/GroupSettleup.tsx`:
- Around line 43-55: Update the sender/receiver selection in GroupSettleup to
use the original signed balance direction rather than the absolute amount,
preserving the source direction for both positive and negative values. Derive
payerRole and receiverRole from data?.user.id, not the balance-row user
variable, while leaving the payment text choices unchanged.
In `@src/components/SimpleConfirmationDialog.tsx`:
- Around line 44-53: Update the dialog props and `isControlled`/`setOpen` logic
in `SimpleConfirmationDialog` to use a discriminated union: controlled usage
must require both `open` and `onOpenChange`, while uncontrolled usage must omit
them or use the internal state path. Remove the non-null assertion on
`controlledOnOpenChange` and ensure `handleSubmit` closes through a safely
narrowed `setOpen` callback.
In `@src/pages/_app.tsx`:
- Around line 141-154: Update the preferred-language synchronization in _app’s
updateUser.mutateAsync chain to use the project’s mutation-error handling
pattern, calling the translated toast error with errors.language_change_failed
when saving fails instead of only logging the error.
In `@src/utils/strings.ts`:
- Around line 67-70: Update the selectedParticipants filter predicate so the
undefined comparison uses Yoda condition order, changing the share check to
place undefined on the left while preserving the existing behavior and 0n !==
share comparison.
