Em dashes (—) and en dashes (–) had spread across comments, docs, tests, and a few UI strings, reading as AI-generated boilerplate rather than house style. Replaced each with punctuation matching its context: colon for explanatory clauses, comma for asides, plain hyphen for numeric/legal ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for paired-dash asides. messages/en.json and messages/sv.json were fixed by hand together to keep sv/en in sync. Left untouched where the dash is the functional subject rather than decorative punctuation: date-range-parser.ts's separator regex, charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the agent system-prompt files that already instruct against em dashes, and a golden iXBRL test fixture compared byte-for-byte. Also fixes two bugs surfaced along the way: an off-by-one in ApiKeysPanel's scope-label split (a leftover from an earlier partial pass), and a charset-repair test that had lost the literal en-dash it exists to verify. Regenerated the agent atom seed migration (skills:generate) since 27 SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes, with an explicit carve-out for the functional-dash cases above. Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com>

# i18n
|
|
|
|
The app is Swedish-first and bilingual (Swedish + English) for UI chrome. Locale is per-user on `user_preferences.locale` (`'sv' | 'en'`, default `'sv'`), resolved server-side via next-intl. The user picker lives at `/settings/account`.
|
|
|
|
**Pattern for new UI:**
|
|
|
|
```tsx
|
|
// Server component
|
|
import { getTranslations } from 'next-intl/server'
|
|
const t = await getTranslations('namespace')
|
|
|
|
// Client component
|
|
'use client'
|
|
import { useTranslations } from 'next-intl'
|
|
const t = useTranslations('namespace')
|
|
|
|
// In JSX
|
|
<button>{t('save')}</button>
|
|
```
|
|
|
|
Add new strings to both `messages/sv.json` and `messages/en.json` under the matching namespace (`common`, `nav`, `auth`, `settings`, `empty`, etc.). Never ship an English key without a Swedish counterpart: Swedish is the default and the fallback.
|
|
|
|
**Locale-aware formatters:**
|
|
- `formatCurrency(amount)`: stays SEK with sv-SE conventions in BOTH locales (Swedish accounting standard, not a UI string).
|
|
- `formatDate(date)`: ISO `yyyy-MM-dd`, locale-independent.
|
|
- `formatDateLong(date, locale)`: accepts locale. In client components use `useFormat()` (`lib/hooks/use-format.ts`) which pulls the active locale.
|
|
|
|
**Error messages:** `getErrorMessage(err, { locale, context })` from `lib/errors/get-error-message.ts` is bilingual on the primary maps (Postgres codes, HTTP statuses, context fallbacks, generic fallback). The structured error envelope (`{ error: { code, message, message_en } }`) already carries both; the function picks the right one from `locale`. Pass `useLocale()` / `getLocale()` as the locale arg.
|
|
|
|
**Stays Swedish: do NOT translate:**
|
|
|
|
| Surface | Reason |
|
|
|---|---|
|
|
| Invoice PDFs (`lib/invoices/pdf-template.tsx`) | Customer-facing: driven by `customer.language` (`sv` default, `en` opt-in). The template's chrome translates; statutory chapter refs (ML 17 kap 24§, ML 3 kap.) stay intact in both locales. |
|
|
| Customer email templates (`lib/email/invoice-templates.ts`, `reminder-templates.ts`) | Same: `customer.language` drives the output. `reminder-templates.ts` is still Swedish-only; mirror the PDF/invoice-templates approach if you add English here. |
|
|
| Year-end wizard (`app/(dashboard)/bookkeeping/year-end/page.tsx`) | Statutory bokslut terminology; English would be misleading |
|
|
| Journal entry editor (`app/(dashboard)/bookkeeping/[id]/page.tsx`) | Deeply regulatory (verifikat, voucher numbers, BAS) |
|
|
| INK2 / NE-bilaga / SRU (`lib/reports/ink2/**`, `lib/reports/ne-bilaga/**`, `lib/reports/sru-*`) | Skatteverket forms: field codes and labels are statutory |
|
|
| SIE export (`lib/reports/sie-export.ts`) | SIE format is Swedish-only by spec (#KONTO, #VER, etc.) |
|
|
| BAS chart names (`lib/bookkeeping/bas-data/**`) | Standardized Swedish account names per BAS 2026 |
|
|
| VAT declaration ruta labels (`lib/reports/vat-declaration*.ts`) | Momsdeklaration field labels are Skatteverket form labels |
|
|
| Salary AGI / KU (`lib/salary/agi*`, `lib/salary/ku*`) | Skatteverket-bound forms |
|
|
| Bookkeeping engine domain errors ("Verifikationen balanserar inte", "Bokföringen är låst") | Regulatory concepts; English equivalents would be ambiguous |
|
|
|
|
Anything in the table above stays Swedish in BOTH locales. If you find yourself reaching for `t()` inside one of these files, stop and reconsider.
