# MalioDateTime Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Ajouter un composant `MalioDateTime` (date + heure dans un seul champ) à la famille temporelle de `@malio/layer-ui`, en version intérimaire avec `<input type="time">` natif.

**Architecture:** Fine enveloppe autour du shell `internal/CalendarField.vue` (comme `MalioDate`). Le slot popover contient `MonthGrid` (jour) + un `<input type="time">` (heure) sous la grille. La valeur émise est l'ISO naïf `"YYYY-MM-DDTHH:MM:00"`. Logique de découpe/recomposition dans un nouveau composable `datetimeFormat.ts`.

**Tech Stack:** Vue 3 `<script setup lang="ts">`, TypeScript strict, Tailwind (`m-*`), `tailwind-merge`, Vitest + @vue/test-utils (jsdom).

**Conventions (rappel) :** Conventional Commits **avec espace avant `:`**, type minuscule, suffixe ticket `(#MUI-33)`, pas de préfixe `[#...]`. Terminer par `Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>`. Le hook pre-commit est flaky (timeouts WSL2) → après vérification ciblée `npx vitest run <chemin>`, committer avec `--no-verify`.

### Task 1 : Composable `datetimeFormat.ts`

**Files:**
- Create: `app/components/malio/date/composables/datetimeFormat.ts`
- Test: `app/components/malio/date/composables/datetimeFormat.test.ts`

- [ ] **Step 1 : Écrire les tests qui échouent**

Créer `app/components/malio/date/composables/datetimeFormat.test.ts` :

- [ ] **Step 2 : Lancer les tests pour vérifier qu'ils échouent**

Run: `npx vitest run app/components/malio/date/composables/datetimeFormat.test.ts`
Expected: FAIL (module `./datetimeFormat` introuvable).

- [ ] **Step 3 : Écrire l'implémentation**

Créer `app/components/malio/date/composables/datetimeFormat.ts` :

### Task 3 : Page playground + entrée nav

**Files:**
- Create: `.playground/pages/composant/date/datetime.vue`
- Modify: `.playground/playground.nav.ts` (section `DATES & HEURES`)

- [ ] **Step 1 : Créer la page playground**

Créer `.playground/pages/composant/date/datetime.vue` :

```vue
<template>
  <div class="space-y-6 p-4">
    <h1 class="text-2xl font-bold">MalioDateTime</h1>

    <div class="flex flex-wrap items-start gap-10">
      <div class="w-[396px] space-y-3">
        <h2 class="font-semibold">Simple</h2>
        <MalioDateTime
          v-model="value"
          label="Date et heure du rendez-vous"
          hint="Choisis un jour puis une heure"
        />
        <div class="rounded border p-3 text-sm">
          <p>Valeur (ISO naïf) : <code>{{ value ?? 'null' }}</code></p>
        </div>
        <button
          type="button"
          class="rounded border px-3 py-1.5"
          @click="value = null"
        >
          Réinitialiser
        </button>
      </div>

      <div class="w-[396px] space-y-3">
        <h2 class="font-semibold">Valeur initiale + bornes</h2>
        <MalioDateTime
          v-model="bounded"
          label="Créneau"
          :min="todayIso"
          :max="maxIso"
          hint="Entre aujourd'hui et +30 jours"
        />
        <div class="rounded border p-3 text-sm">
          <p>Valeur (ISO naïf) : <code>{{ bounded ?? 'null' }}</code></p>
        </div>
      </div>
    </div>
  </div>
</template>

<script setup lang="ts">
import {ref} from 'vue'

const pad = (n: number) => String(n).padStart(2, '0')
const toIso = (d: Date) => `${d.getFullYear()}-${pad(d.getMonth() + 1)}-${pad(d.getDate())}T00:00:00`
const now = new Date()
const todayIso = toIso(now)
const maxIso = toIso(new Date(now.getTime() + 30 * 86400000))

const value = ref<string | null>(null)
const bounded = ref<string | null>('2026-05-20T14:30:00')
</script>
```

- [ ] **Step 2 : Ajouter l'entrée nav**

Dans `.playground/playground.nav.ts`, section `DATES & HEURES`, ajouter l'item après `Semaine` :

```ts
      {label: 'Date & heure', to: '/composant/date/datetime'},
```

Le bloc devient :

```ts
    items: [
      {label: 'Date', to: '/composant/date/date'},
      {label: 'Plage de dates', to: '/composant/date/dateRange'},
      {label: 'Semaine', to: '/composant/date/dateWeek'},
      {label: 'Date & heure', to: '/composant/date/datetime'},
      {label: 'Heure', to: '/composant/time/time'},
    ],
```

- [ ] **Step 3 : Vérifier le lint**

Run: `npm run lint`
Expected: PASS (pas d'erreur sur les fichiers playground).

- [ ] **Step 4 : Commit**

```bash
git add .playground/pages/composant/date/datetime.vue .playground/playground.nav.ts
git commit --no-verify -m "feat : page playground MalioDateTime (#MUI-33)

### Task 5 : Documentation (COMPONENTS.md + CHANGELOG.md)

**Files:**
- Modify: `COMPONENTS.md`
- Modify: `CHANGELOG.md`

- [ ] **Step 1 : Ajouter la section dans COMPONENTS.md**

Ouvrir `COMPONENTS.md`, repérer la section `MalioDate` (ou la famille date) et ajouter une section `MalioDateTime` calquée dessus, documentant :
- Description : champ unique date + heure, popover (grille + sélecteur d'heure), version intérimaire avec `<input type="time">` natif.
- `modelValue` : `string | null`, format `"YYYY-MM-DDTHH:MM:00"` (ISO naïf sans fuseau ; Symfony applique son fuseau).
- Table des props identique à `MalioDate` (ajouter la note sur `min`/`max` bornant la date).
- Émission `update:modelValue`.
- Exemple d'usage :

```vue
<MalioDateTime v-model="rdv" label="Date et heure du rendez-vous" />
<!-- rdv === "2026-05-20T14:30:00" -->
```

- Note : le sélecteur d'heure est intérimaire et sera remplacé par un composant dédié (maquette à venir).

Respecter le style et la structure exacts des sections existantes (titres, tableaux markdown).

- [ ] **Step 2 : Ajouter l'entrée CHANGELOG.md**

Dans `CHANGELOG.md`, sous `## [0.0.0]` → `### Added`, ajouter après la ligne `[#MUI-33] Développer le composant Datepicker` :

```
* [#MUI-33] Création du composant DateTime (date + heure, sélecteur d'heure natif intérimaire)
```

- [ ] **Step 3 : Commit**

```bash
git add COMPONENTS.md CHANGELOG.md
git commit --no-verify -m "docs : documente MalioDateTime (COMPONENTS + CHANGELOG) (#MUI-33)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>"

## Vérification finale

- [ ] `npx vitest run app/components/malio/date/` → toute la famille date verte.
- [ ] `npm run lint` → pas d'erreur.
- [ ] Revue finale du composant (cohérence avec la famille date, isolation du bloc heure pour remplacement futur).
