Jean-Luc Makiola 45ca3243fe core-locale: locale-aware date formatting (currentLocale, localizedDateFormatter)
Both functions lived in Calendula's ui/common/LocaleSupport.kt. Neither is
calendar-specific — "lay this date out the way this language writes dates" is
family plumbing — so they move here, where Agendula can reach them too.

localizedDateFormatter(locale, skeleton) takes a field list ("LLLLy", "dMMMy")
and lets the locale arrange it, which is the only way to render a date correctly
in a language you didn't hand-write a template for. Dropping a field from the
skeleton drops it from the output, so callers ask for "no year" by omitting it
rather than post-processing a longer pattern.

currentLocale() reads the display locale from LocalConfiguration. This module's
own AppLanguage.apply() changes the language inside a running process, so a
locale captured once goes stale; keying on the configuration makes the UI follow
the switch.

core-locale gains Compose (runtime + ui only) for currentLocale(). Its build file
previously declared itself Compose-free, but the alternative — parking the hook
in a Compose module that depends back on this one — splits one concern across two
modules to honour a comment. core-crash is the precedent for a core-* module
carrying Compose.

Leaves core-time's Instant.formatDate() family alone despite the overlap: it is
unused by Calendula but visible to Agendula, so reconciling it is that app's
call, not a drive-by here. Noted in the changelog.

# Changelog
All notable changes to floret-kit are documented here. The format follows
[Keep a Changelog](https://keepachangelog.com/).
floret-kit is consumed **from source** — each app embeds it as a git submodule
and builds it through a Gradle composite build, pinning a specific commit. There
are no binary releases; "version" tracks the shared `version` in the root build
(currently `0.1.0`). Entries are grouped by module.
## [Unreleased]
### Added
- **`core-locale`** — the locale-aware formatting half of the module, so apps
stop hand-rolling `"$day. $month $year"` templates that bake one language's
field order (and its separators, and its ordinal dot) into every language they
ship:
- `localizedDateFormatter(locale, skeleton)` — a `DateTimeFormatter` for a
field skeleton ("LLLLy", "dMMMy", "EEEdMMM") laid out in the locale's own
order, via Android's best-pattern matching. Drop a field from the skeleton to
drop it from the output — the locale still supplies the arrangement.
- `currentLocale()` — the display locale, observed from `LocalConfiguration`.
Since `AppLanguage.apply()` changes the language inside a running process, a
locale captured once goes stale; this keys recomposition to the change.
### Changed
- **`core-locale`** now carries Compose (runtime + ui only) for `currentLocale()`.
The module previously declared itself Compose-free; applying a language
mid-process is its own API, so the hook that makes the UI notice belongs beside
it rather than in a Compose module depending back on this one. `core-crash` is
the precedent for a `core-*` module carrying Compose.
### Known gaps
- `core-time`'s `Instant.formatDate()` family now overlaps `core-locale`. Its
private `dateNoYearFormatter` strips the year by regex-ing the pattern string,
which `localizedDateFormatter(locale, "dMMM")` does properly; and its
formatters resolve `Locale.getDefault()` once at class-init ("locale changes
within a running process are rare enough to ignore"), which `AppLanguage.apply()`
makes untrue. Left alone for now — it is unused by Calendula but Agendula-visible.
Reconcile when Agendula next re-pins.
## [0.1.0] - 2026-07-07
### Added
- **`core-time`** (JVM library) — pure-Kotlin date/time helpers, no Android and
no third-party dependencies:
- `DayWindow.today()` — local-day boundaries for smart-list logic.
- `Instant.formatDate()` / `formatTime()` / `formatDateTime()` — locale- and
zone-aware display formatting over `kotlin.time.Instant`.
- `TimeBridge``Long` epoch-millis ↔ `Instant`, for content-provider I/O.
- `LocalDate.isoWeekNumber()` — ISO-8601 week-of-week-based-year, the
calendar-week number for week/month grids (one scheme, shared).
- **`core-crash`** (Android library) — privacy-respecting, on-device crash
capture and reporting. Writes an allowlist-only report (app/Android/device
version, locale, time, stack trace — nothing else) to private storage and
chains to the platform handler; uploads nothing. Includes startup crash-loop
detection, a report dialog that shows the full text before it leaves the
device, and an issue-tracker hand-off. Per-app specifics (display name, issue
URLs) come from a `CrashConfig` supplied at `install()`; each app keeps its
own thin themed `CrashReportActivity`.
- **`identity`** (Android library) — the family's Material 3 Expressive theme
factory `FloretExpressiveTheme(lightScheme, darkScheme, …)` (dynamic colour on
API 31+, system light/dark fallback, the standard motion scheme) plus the
shared motion helpers — `rememberNavSlideSpec()`, the content transitions,
`Modifier.predictiveBack()` and `Modifier.animateContentSizeMotion()` (eases a
block's own height changes, e.g. a text field wrapping to a new line), each
reduced-motion-aware. Each app passes its own seed-derived colour schemes
and typography — the mechanics are shared, the look is not.
- **`components`** (Android library) — the shared Compose component vocabulary:
- `GroupedSurface` / `GroupedRow` + `Position` / `positionOf` — the canonical
press-morphing tonal grouped-row primitive (the Android-15 settings pattern).
- `InlineTextField` — the borderless tonal text input (capitalization is a
parameter).
- `OptionCard` — the sanctioned selection-dialog pick.
- `CollapsingScaffold` — the collapsing settings/sub-screen scaffold; set
`largeTopBar = false` for a pinned single-line bar (the picker variant).
- `FullScreenPicker` / `OptionPicker` — the full-screen single-select picker,
now over a pinned single-line bar (a picker is a short list, so no tall
collapsing header to scroll past). `FullScreenPicker` takes an optional
`actions` slot (app-bar trailing items) for pickers that carry a commit or
extra action — a custom-value **Add**/**OK**, a **Reset**.
- `ReorderableColumn` — dependency-free drag-to-reorder for the short, fixed
grouped-card Settings lists; pairs with `GroupedRow(gapBelow = false)`, which
hands the column uniform control of row spacing.
- `DebugRibbon` — a stark, un-themed "DEBUG" corner ribbon; gate on
`BuildConfig.DEBUG` at the call site.
- `InlineTextField` gained `enabled` (a disabled field dims to a locked value).
- `pastelize()` — softens a raw provider colour to a theme-fitting pastel.
App-agnostic by design: apps compose their own screens and keep their own
identity chips/icons. String resources here (e.g. `back`) are fallbacks an app
can override.
- **`core-reminders`** (JVM library) — the app-agnostic reminder-override model:
`ReminderOverride` (`Inherit` / `None` / `Minutes`), where `Minutes` carries a
**list** of lead-times so a target can hold several reminders at once (an app
that offers a single reminder just uses a one-element list). Map helpers
(`reminderOverrideFor`, `reminderLeadsFor`, `applyReminderOverride`,
`reminderOverrideForMinutes`, `normalizeReminders`) plus `ReminderOverrideCodec`
(three configurable separators; single legacy values round-trip byte-identically)
and the lead-time unit model (`ReminderUnit`, `decomposeReminderMinutes`). The
labels/presets and the alarm scheduler stay per-app.
### Conventions
- **No `foojay` toolchain resolver** anywhere — it can fetch a JDK at build time,
which reproducible / official F-Droid builds reject. Modules set `jvmTarget`
directly. See [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md).
- AGP 9.x provides built-in Kotlin compilation, so Android modules apply only the
Android library + Compose plugins (no separate `kotlin.android`).
