Language Configuration Fix for YouTube vs Text Processing

Working Configuration

ChatService.ts

• Simple language handling that works:

// Add language instruction at end of input
userInput: userInput + languageInstruction

ChatInput.svelte

• Store and restore language state:

// Store original language
const originalLanguage = get(languageStore);

// Restore before processing
languageStore.set(originalLanguage);

// Pass isYouTubeTranscript flag
await sendMessage(transcript, $systemPrompt, false, true);

chat/+server.ts

• Pass language through transcript service:

const response = {
  transcript,
  title: videoId,
  language: body.language
};

Issue to Fix: Transcript Display

The transcript is showing in browser before pattern output because it's being added to the message store. The fix needs to:

1. Keep the "Processing YouTube transcript..." message
2. Skip adding the raw transcript to message store
3. Only show the pattern output when it comes back

Location of Fix

In chat-store.ts:

// Add isYouTubeTranscript parameter to skip adding transcript
export async function sendMessage(content: string, systemPromptText?: string, isSystem: boolean = false, isYouTubeTranscript: boolean = false)

// Skip only the transcript, not system messages
if (isYouTubeTranscript && !isSystem) {
  // Skip only transcript
  return;
}
messageStore.update(messages => [...messages, { 
  role: isSystem ? 'system' : 'user', 
  content 
}]);

Testing

1. Regular text with --fr:

   • Should show message in chat
   • Should process in French

2. YouTube with --fr:

   • Should show "Processing..." message (isSystem=true)
   • Should NOT show transcript (isYouTubeTranscript=true)
   • Should show pattern output in French (language preserved) The language-config-fix.md contains valuable insights directly relevant to our current investigation.

Key findings from language-config-fix.md:

Previous fix involved handling language state across YouTube transcript processing: // Store original language const originalLanguage = get(languageStore);

// Restore before processing languageStore.set(originalLanguage);

YouTube transcript handling had special flags: await sendMessage(transcript, $systemPrompt, false, true); // The last parameter isYouTubeTranscript was added

Chat store modifications: // Skip only the transcript, not system messages if (isYouTubeTranscript && !isSystem) { return; }

This reveals:

YouTube transcripts have special processing requirements Language state needs preservation during transcript handling The chat store treats YouTube transcripts differently Next steps to explore:
