# X to Kindle

Convert X/Twitter posts into Kindle-readable documents via email.

## Requirements

- Gmail account with App Password (or other SMTP setup)
- Kindle email address (found in Amazon account settings)

## Workflow

When user shares an X link:

1. **Extract content** via fxtwitter API:
   ```
   https://api.fxtwitter.com/status/<tweet_id>
   ```
   Extract from URL: `twitter.com/*/status/<id>` or `x.com/*/status/<id>`

2. **Format as HTML file** (save to /tmp):
   ```html
   <!DOCTYPE html>
   <html>
   <head><meta charset="UTF-8"><title>{title}</title></head>
   <body style="font-family: Georgia, serif; max-width: 600px; margin: 0 auto; padding: 20px; line-height: 1.6;">
     <h1>@{author_handle}</h1>
     <p>{tweet_text}</p>
     <p><em>{timestamp}</em></p>
     <p><a href="{original_url}">View on X</a></p>
   </body>
   </html>
   ```

3. **Send via SMTP with HTML as ATTACHMENT** (Kindle requires attachment, not inline HTML):
   ```python
   from email.mime.multipart import MIMEMultipart
   from email.mime.text import MIMEText
   from email.mime.base import MIMEBase
   from email import encoders
   
   msg = MIMEMultipart()
   msg['Subject'] = "Tweet from @handle"
   msg['From'] = from_email
   msg['To'] = kindle_email
   
   # Plain text body (not the content)
   msg.attach(MIMEText("Article attached.", 'plain'))
   
   # HTML file as attachment - THIS IS REQUIRED
   with open("/tmp/article.html", "rb") as f:
       attachment = MIMEBase('text', 'html')
       attachment.set_payload(f.read())
       encoders.encode_base64(attachment)
       attachment.add_header('Content-Disposition', 'attachment', filename='article.html')
       msg.attach(attachment)
   ```
