vimwiki's `diary_frequency` config has been honoured by the existing
`nuwiki.diary.openToday` / `openYesterday` / `openTomorrow` commands
end-to-end. Setting `diary_frequency = 'weekly'` (or `monthly` /
`yearly`) now creates and addresses entries at that cadence — file
stems follow the canonical formats:
daily YYYY-MM-DD 2026-05-12.wiki
weekly YYYY-Www 2026-W19.wiki (ISO 8601 week)
monthly YYYY-MM 2026-05.wiki
yearly YYYY 2026.wiki
Core additions (nuwiki_core::date):
- DiaryFrequency enum + permissive `parse` (unknown → Daily)
- DiaryPeriod enum unifying Day / Week / Month / Year
- format / parse / next / prev / today_utc + first_day, with
proper ISO-week math (Thursday rule, year-boundary handling)
LSP wiring:
- WikiConfig::frequency() and diary_path_for_period()
- crate::diary::uri_for_period
- Index now records `diary_period` for any of the four flavours;
`diary_date` is preserved (filtered to Day-only) for back-compat
with existing daily-only callers
- `nuwiki.diary.next` / `nuwiki.diary.prev` now navigate at the
*same flavour* as the current entry (or at the wiki's configured
frequency when off a diary page), via new
`crate::diary::next_period` / `prev_period` helpers
- `nuwiki.diary.openToday` returns the period stem + frequency in
its response payload alongside the URI
Tests:
- 12 in crates/nuwiki-core/tests/diary_period.rs covering the date
math (ISO week boundaries, format round-trips, next/prev across
year edges, etc.)
- 9 in crates/nuwiki-lsp/tests/diary_frequency.rs covering
WikiConfig path computation, index recognition for all four
stems, period navigation, and diary-dir filtering
Gates: 450 Rust / 39 Neovim / 12 Vim.
