feat: add hashtag support to rich editor (#185)

* feat: add automatic hashtag extraction and t tags in POST command Extract hashtags from post content and automatically add them as t tags to published events. Changes: - Add hashtag extraction logic to RichEditor.serializeContent() using Unicode-aware regex - Update SerializedContent interface to include hashtags field - Update RichEditor props and callbacks to pass hashtags through the pipeline - Add t tags for each hashtag in PostViewer.handlePublish() Hashtags are deduplicated and stored in lowercase (following Nostr convention). Example: #bitcoin #nostr #Bitcoin → ["t", "bitcoin"], ["t", "nostr"] * refactor: use NoteBlueprint for automatic hashtag/mention extraction Replace manual hashtag and mention extraction with applesauce's NoteBlueprint, which automatically extracts hashtags, mentions, and event quotes from text content. Changes: - Simplify SerializedContent interface by removing manually extracted fields - Remove hashtag extraction regex and mention/eventRef tracking from editors - Replace manual event building with factory.create(NoteBlueprint, ...) - Use q tags for event quotes (NIP-18) instead of e tags Benefits: - ~70 lines of code removed - Leverage battle-tested applesauce extraction logic - Automatic benefits from future applesauce improvements - Correct semantic tags (q for quotes, p for mentions, t for hashtags) What still works: - Custom emoji tags (NIP-30) - Blob attachments/imeta tags (NIP-92) - Address references (naddr - not yet in applesauce) - Client tag All tests pass (980/980). * refactor: use NoteReplyBlueprint in NIP-10 adapter Replace manual NIP-10 tag building with NoteReplyBlueprint, which automatically handles root/reply markers, p-tag copying, and all the threading logic. Changes: - Simplify sendMessage from ~95 lines to ~40 lines - Remove manual e-tag building with root/reply markers - Remove manual p-tag deduplication logic - Use factory.create(NoteReplyBlueprint, parentEvent, content, options) - Automatically get hashtags, mentions, and event quotes via setShortTextContent Benefits: - ~55 lines of complex threading logic removed - Leverage battle-tested applesauce NIP-10 implementation - Automatic root detection from parent's existing tags - Cleaner, more maintainable code All tests pass (980/980). * refactor: use GroupMessageBlueprint and ReactionBlueprint in chat adapters Replace manual event building with applesauce blueprints in all chat adapters. Changes: - NIP-29: Use GroupMessageBlueprint for kind 9 messages * Auto-handles h-tag, hashtags, mentions, emojis * Manually add q-tag for replies (NIP-29 specific) * ~15 lines removed - All adapters (NIP-10, NIP-29, NIP-53, NIP-C7): Use ReactionBlueprint for kind 7 reactions * Auto-handles e-tag, k-tag, p-tag, custom emoji support * Protocol-specific tags (h-tag, a-tag) added manually * ~60 lines removed across 4 adapters Benefits: - ~75 lines of code removed total - Leverage battle-tested applesauce blueprints - Automatic hashtag, mention, and quote extraction - Cleaner, more maintainable code All tests pass (980/980). * fix: add required previous field to GroupMessageBlueprint options GroupMessageBlueprintOptions requires a 'previous' field for message threading. Added empty array for now since we don't support threading yet. * docs: add comprehensive blueprint documentation to applesauce skills Added detailed documentation for: - NoteBlueprint (automatic hashtag/mention/quote extraction) - NoteReplyBlueprint (NIP-10 threading) - ReactionBlueprint (kind 7 reactions) - GroupMessageBlueprint (NIP-29 groups) - DeleteBlueprint (NIP-09 deletion) - EventFactory usage patterns - Before/after examples showing code reduction - Best practices for using blueprints This documents the refactoring work done throughout the codebase. * fix: use single newline separator in TipTap getText() calls TipTap's getText() uses double newlines (\n\n) by default to separate block nodes like paragraphs, which was causing extra blank lines in posted content. Changed to getText({ blockSeparator: '\n' }) in both RichEditor and MentionEditor to use single newlines between paragraphs. --------- Co-authored-by: Claude <noreply@anthropic.com>

 ## Blueprints

-Blueprints provide templates for creating events.
+Blueprints are factory functions that create Nostr events with automatic tag extraction and proper NIP compliance. They eliminate manual tag building and reduce boilerplate code significantly.
+
+### Key Benefits
+
+1. **Automatic Tag Extraction**: Blueprints automatically extract hashtags (#word), mentions (nostr:npub), and event quotes (nostr:note/nevent) from text content
+2. **NIP Compliance**: Each blueprint follows the correct NIP specifications for its event type
+3. **Less Code**: Replace 50-100 lines of manual tag building with 5-10 lines
+4. **Type Safety**: Full TypeScript support with proper types for all options
+5. **Maintainable**: Centralized event building logic that's easier to update
+
+### Using Blueprints

 ```typescript
 import { EventFactory } from 'applesauce-core/event-factory';
 import { NoteBlueprint } from 'applesauce-common/blueprints';

-const factory = new EventFactory({ signer });
-
-// Create a note using blueprint
-const draft = await factory.build(NoteBlueprint({
-  content: 'Hello Nostr!',
-  tags: [['t', 'nostr']]
-}));
+const factory = new EventFactory();
+factory.setSigner(signer);

+// Create event from blueprint
+const draft = await factory.create(NoteBlueprint, content, options);
 const event = await factory.sign(draft);
 ```

+### NoteBlueprint (Kind 1)
+
+Creates short text notes with automatic hashtag, mention, and quote extraction.
+
+**What it handles automatically:**
+- Extracts `#hashtags` from content → `t` tags
+- Extracts `nostr:npub...` mentions → `p` tags
+- Extracts `nostr:note...` and `nostr:nevent...` quotes → `q` tags (NIP-18)
+- Adds custom emoji tags (NIP-30)
+
+```typescript
+import { NoteBlueprint } from 'applesauce-common/blueprints';
+
+// Simple note
+const draft = await factory.create(
+  NoteBlueprint,
+  'Hello #nostr! Check out nostr:npub1abc...',
+  {}
+);
+
+// With custom emojis
+const draft = await factory.create(
+  NoteBlueprint,
+  'Hello :rocket:!',
+  {
+    emojis: [{ shortcode: 'rocket', url: 'https://example.com/rocket.png' }]
+  }
+);
+
+// The blueprint automatically adds:
+// - ["t", "nostr"] for #nostr
+// - ["p", "decoded-pubkey"] for the npub mention
+// - ["emoji", "rocket", "https://example.com/rocket.png"] for custom emoji
+```
+
+**Options:**
+- `emojis?: Array<{ shortcode: string; url: string }>` - Custom emojis (NIP-30)
+- `contentWarning?: boolean | string` - Content warning tag
+
+**Before/After Example:**
+```typescript
+// ❌ BEFORE: Manual tag building (~70 lines)
+const hashtags = content.match(/#(\w+)/g)?.map(tag => tag.slice(1)) || [];
+const mentionRegex = /nostr:(npub1[a-z0-9]+)/g;
+const mentions = [];
+let match;
+while ((match = mentionRegex.exec(content)) !== null) {
+  try {
+    const { data } = nip19.decode(match[1]);
+    mentions.push(data);
+  } catch (e) { /* ignore */ }
+}
+// ... more extraction logic ...
+draft.tags = [
+  ...hashtags.map(t => ['t', t]),
+  ...mentions.map(p => ['p', p]),
+  // ... more tags ...
+];
+
+// ✅ AFTER: Blueprint handles everything
+const draft = await factory.create(NoteBlueprint, content, { emojis });
+```
+
+### NoteReplyBlueprint (Kind 1 Reply)
+
+Creates threaded note replies following NIP-10 conventions.
+
+**What it handles automatically:**
+- Extracts root event from parent's tags (NIP-10)
+- Adds proper `e` tags with markers (root, reply)
+- Copies `p` tags from parent for notifications
+- Extracts hashtags, mentions, and quotes from content
+- Uses `q` tags for quotes instead of `e` tags (correct semantic)
+
+```typescript
+import { NoteReplyBlueprint } from 'applesauce-common/blueprints';
+
+// Reply to a note
+const parentEvent = await eventStore.event(parentId).toPromise();
+
+const draft = await factory.create(
+  NoteReplyBlueprint,
+  parentEvent,
+  'Great point! #bitcoin',
+  {
+    emojis: [{ shortcode: 'fire', url: 'https://example.com/fire.png' }]
+  }
+);
+
+// The blueprint automatically:
+// 1. Finds root from parent's tags (if parent is also a reply)
+// 2. Adds ["e", rootId, relay, "root"]
+// 3. Adds ["e", parentId, relay, "reply"]
+// 4. Copies all ["p", ...] tags from parent
+// 5. Extracts #bitcoin → ["t", "bitcoin"]
+// 6. Adds emoji tag
+```
+
+**Options:**
+- `emojis?: Array<{ shortcode: string; url: string }>` - Custom emojis
+- `contentWarning?: boolean | string` - Content warning
+
+**Before/After Example:**
+```typescript
+// ❌ BEFORE: Manual NIP-10 threading (~95 lines)
+const parentRefs = getNip10References(parentEvent);
+const rootId = parentRefs.root?.e || parentEvent.id;
+const rootRelay = parentRefs.root?.relay || '';
+
+draft.tags = [
+  ['e', rootId, rootRelay, 'root'],
+  ['e', parentEvent.id, '', 'reply'],
+];
+
+// Copy p-tags from parent
+const parentPTags = parentEvent.tags.filter(t => t[0] === 'p');
+draft.tags.push(...parentPTags);
+if (!parentPTags.some(t => t[1] === parentEvent.pubkey)) {
+  draft.tags.push(['p', parentEvent.pubkey]);
+}
+// ... hashtag extraction ...
+// ... mention extraction ...
+
+// ✅ AFTER: Blueprint handles NIP-10 threading
+const draft = await factory.create(
+  NoteReplyBlueprint,
+  parentEvent,
+  content,
+  { emojis }
+);
+```
+
+### ReactionBlueprint (Kind 7)
+
+Creates reactions to events (likes, custom emoji reactions).
+
+**What it handles automatically:**
+- Adds `e` tag pointing to reacted event
+- Adds `k` tag for event kind
+- Adds `p` tag for event author
+- Handles custom emoji reactions (`:shortcode:` format)
+- Supports both string emoji and Emoji objects
+
+```typescript
+import { ReactionBlueprint } from 'applesauce-common/blueprints';
+
+// Simple like (+ emoji)
+const draft = await factory.create(ReactionBlueprint, messageEvent, '+');
+
+// Custom emoji reaction
+const draft = await factory.create(
+  ReactionBlueprint,
+  messageEvent,
+  {
+    shortcode: 'rocket',
+    url: 'https://example.com/rocket.png'
+  }
+);
+
+// String emoji
+const draft = await factory.create(ReactionBlueprint, messageEvent, '🚀');
+
+// The blueprint automatically adds:
+// - ["e", messageEvent.id]
+// - ["k", messageEvent.kind.toString()]
+// - ["p", messageEvent.pubkey]
+// For custom emoji: ["emoji", "rocket", "url"]
+```
+
+**Options:**
+- Second parameter: `emoji?: string | { shortcode: string; url: string }`
+
+**Before/After Example:**
+```typescript
+// ❌ BEFORE: Manual reaction building (~15 lines per adapter)
+draft.kind = 7;
+draft.content = typeof emoji === 'string' ? emoji : `:${emoji.shortcode}:`;
+draft.tags = [
+  ['e', messageEvent.id],
+  ['k', messageEvent.kind.toString()],
+  ['p', messageEvent.pubkey],
+];
+if (typeof emoji === 'object') {
+  draft.tags.push(['emoji', emoji.shortcode, emoji.url]);
+}
+
+// ✅ AFTER: Blueprint handles reactions
+const draft = await factory.create(ReactionBlueprint, messageEvent, emoji);
+```
+
+### GroupMessageBlueprint (Kind 9 - NIP-29)
+
+Creates NIP-29 group chat messages.
+
+**What it handles automatically:**
+- Adds `h` tag with group ID
+- Extracts hashtags, mentions, and quotes from content
+- Adds custom emoji tags
+- Handles message threading with `previous` field
+
+```typescript
+import { GroupMessageBlueprint } from 'applesauce-common/blueprints';
+
+// Send message to NIP-29 group
+const draft = await factory.create(
+  GroupMessageBlueprint,
+  { id: groupId, relay: relayUrl },
+  'Hello group! #welcome',
+  {
+    previous: [], // Array of previous message events for threading
+    emojis: [{ shortcode: 'wave', url: 'https://example.com/wave.png' }]
+  }
+);
+
+// The blueprint automatically adds:
+// - ["h", groupId]
+// - ["t", "welcome"] for #welcome hashtag
+// - ["emoji", "wave", "url"] for custom emoji
+```
+
+**Options:**
+- `previous?: NostrEvent[]` - Previous messages for threading (required, use `[]` if no threading)
+- `emojis?: Array<{ shortcode: string; url: string }>` - Custom emojis
+
+**Note:** The `previous` field is required by the type, but can be an empty array if you don't need threading.
+
+### DeleteBlueprint (Kind 5 - NIP-09)
+
+Creates event deletion requests.
+
+**What it handles automatically:**
+- Adds `e` tags for each event to delete
+- Sets proper kind and content format
+- Adds optional reason in content
+
+```typescript
+import { DeleteBlueprint } from 'applesauce-common/blueprints';
+
+// Delete single event
+const draft = await factory.create(
+  DeleteBlueprint,
+  [eventToDelete],
+  'Accidental post'
+);
+
+// Delete multiple events
+const draft = await factory.create(
+  DeleteBlueprint,
+  [event1, event2, event3],
+  'Cleaning up old posts'
+);
+
+// Without reason
+const draft = await factory.create(DeleteBlueprint, [event], '');
+
+// The blueprint automatically:
+// - Sets kind to 5
+// - Adds ["e", eventId] for each event
+// - Sets content to reason (or empty)
+```
+
+**Parameters:**
+- `events: (string | NostrEvent)[]` - Events to delete (IDs or full events)
+- `reason?: string` - Optional deletion reason
+
+### Adding Custom Tags
+
+Blueprints handle common tags automatically, but you can add custom tags afterward:
+
+```typescript
+// Create with blueprint
+const draft = await factory.create(NoteBlueprint, content, { emojis });
+
+// Add custom tags not handled by blueprint
+draft.tags.push(['client', 'grimoire', '31990:...']);
+draft.tags.push(['a', `${kind}:${pubkey}:${identifier}`]);
+
+// Add NIP-92 imeta tags for blob attachments
+for (const blob of blobAttachments) {
+  draft.tags.push(['imeta', `url ${blob.url}`, `x ${blob.sha256}`, ...]);
+}
+
+// Sign the modified draft
+const event = await factory.sign(draft);
+```
+
+### Protocol-Specific Tag Additions
+
+Some protocols require additional tags beyond what blueprints provide:
+
+```typescript
+// NIP-29: Add q-tag for replies (not in blueprint yet)
+const draft = await factory.create(GroupMessageBlueprint, group, content, options);
+if (replyToId) {
+  draft.tags.push(['q', replyToId]);
+}
+
+// NIP-53: Add a-tag for live activity context
+const draft = await factory.create(ReactionBlueprint, messageEvent, emoji);
+draft.tags.push(['a', liveActivityATag, relay]);
+```
+
+### Available Blueprints
+
+All blueprints from `applesauce-common/blueprints`:
+
+- **NoteBlueprint** - Kind 1 short text notes
+- **NoteReplyBlueprint** - Kind 1 threaded replies (NIP-10)
+- **ReactionBlueprint** - Kind 7 reactions (NIP-25)
+- **GroupMessageBlueprint** - Kind 9 group messages (NIP-29)
+- **DeleteBlueprint** - Kind 5 deletion requests (NIP-09)
+- **MetadataBlueprint** - Kind 0 profile metadata
+- **ContactsBlueprint** - Kind 3 contact lists
+- **ArticleBlueprint** - Kind 30023 long-form articles (NIP-23)
+- **HighlightBlueprint** - Kind 9802 highlights (NIP-84)
+- **ZapRequestBlueprint** - Kind 9734 zap requests (NIP-57)
+- And more - check `node_modules/applesauce-common/dist/blueprints/`
+
+### Best Practices
+
+1. **Always use blueprints** when creating standard event types - they handle NIPs correctly
+2. **Add custom tags after** blueprint creation for app-specific metadata
+3. **Don't extract tags manually** - let blueprints handle hashtags, mentions, quotes
+4. **Use proper emoji format** - blueprints expect `{ shortcode, url }` objects
+5. **Check blueprint source** - when in doubt, read the blueprint code for exact behavior

+## EventFactory
+
+### Overview
+
+The `EventFactory` class (moved to `applesauce-core/event-factory` in v5) provides a unified API for creating and signing Nostr events using blueprints.
+
+```typescript
+import { EventFactory } from 'applesauce-core/event-factory';
+
+// Create factory
+const factory = new EventFactory();
+
+// Set signer (required for signing)
+factory.setSigner(signer);
+
+// Optional context
+factory.setClient({ name: 'grimoire', address: { pubkey, identifier } });
+```
+
+### Creating Events with Blueprints
+
+Blueprints are templates for event creation. See the **applesauce-common** skill for detailed blueprint documentation.
+
+```typescript
+import { NoteBlueprint, NoteReplyBlueprint } from 'applesauce-common/blueprints';
+
+// Create a note
+const draft = await factory.create(
+  NoteBlueprint,
+  'Hello #nostr!',
+  { emojis: [{ shortcode: 'wave', url: 'https://...' }] }
+);
+
+// Sign the draft
+const event = await factory.sign(draft);
+
+// Or combine: create and sign
+const event = await factory.sign(
+  await factory.create(NoteBlueprint, content, options)
+);
+```
+
+### Factory Methods
+
+```typescript
+// Create from blueprint
+const draft = await factory.create(Blueprint, ...args);
+
+// Sign event template
+const event = await factory.sign(draft);
+
+// Stamp (add pubkey without signing)
+const unsigned = await factory.stamp(draft);
+
+// Build with operations
+const draft = await factory.build(template, ...operations);
+
+// Modify existing event
+const modified = await factory.modify(event, ...operations);
+```
+
+### Using with Actions
+
+EventFactory integrates seamlessly with the action system:
+
+```typescript
+import accountManager from '@/services/accounts';
+import { EventFactory } from 'applesauce-core/event-factory';
+import { NoteBlueprint } from 'applesauce-common/blueprints';
+
+const account = accountManager.active;
+const signer = account.signer;
+
+const factory = new EventFactory();
+factory.setSigner(signer);
+
+// Create and sign
+const draft = await factory.create(NoteBlueprint, content, options);
+const event = await factory.sign(draft);
+
+// Publish
+await pool.publish(relays, event);
+```
+
+### Common Patterns
+
+**Creating with custom tags:**
+```typescript
+// Let blueprint handle automatic extraction
+const draft = await factory.create(NoteBlueprint, content, { emojis });
+
+// Add custom tags afterward
+draft.tags.push(['client', 'grimoire', '31990:...']);
+draft.tags.push(['imeta', `url ${blob.url}`, `x ${blob.sha256}`]);
+
+// Sign
+const event = await factory.sign(draft);
+```
+
+**Error handling:**
+```typescript
+try {
+  const draft = await factory.create(NoteBlueprint, content, options);
+  const event = await factory.sign(draft);
+  await pool.publish(relays, event);
+} catch (error) {
+  if (error.message.includes('User rejected')) {
+    // Handle rejection
+  } else {
+    // Handle other errors
+  }
+}
+```
+
+**Optimistic updates:**
+```typescript
+// Create and sign
+const event = await factory.sign(
+  await factory.create(NoteBlueprint, content, options)
+);
+
+// Add to local store immediately
+eventStore.add(event);
+
+// Publish in background
+pool.publish(relays, event).catch(err => {
+  // Remove from store on failure
+  eventStore.remove(event.id);
+});
+```
