Summary of the Bookmarklet
This bookmarklet is a powerful tool designed to enhance the user experience on specific forums, particularly those using the Xenforo platform. Here’s a detailed breakdown of what it does:
1. Embed Social Media Posts
The bookmarklet can embed posts from various social media platforms directly into forum threads. It supports:
- X (Twitter): Embeds tweets from both x.com and twitter.com.
- Threads.net: Embeds posts from Threads.net.
- Mastodon: Embeds posts from Mastodon instances.
- Bluesky: Embeds posts from Bluesky.
2. Dynamic Height Adjustment
For each embedded post, the bookmarklet uses a technique called MessageChannel to dynamically adjust the height of the iframe to fit the content perfectly. This ensures that users do not have to scroll within the iframe to view the entire post.
3. URL Matching and Replacement
The script uses regular expressions to match URLs of different social media platforms and replace them with iframes that embed the content.
Example:
- If a user posts a link to a tweet, the script will replace that link with an iframe containing the tweet.
- Similarly, links to Threads.net, Mastodon, or Bluesky posts are replaced with iframes embedding those posts.
4. Handling Dynamic Content
The script uses a MutationObserver to monitor changes in the document body. This allows it to handle dynamic content loading, ensuring that newly added links are also processed and embedded correctly.
5. Additional Features for Twitter
For Twitter embeds, the script adds additional links below the embedded tweet:
- Twstalker Links: Links to Twstalker, Archive.org, Archive.is, Nitter, Xcancel, and other archiving services.
- URL Replacement: Automatically replaces x.com URLs with twitter.com URLs in text input fields and editable areas.
6. YouTube Mirror Links
The script also adds mirror links for YouTube videos embedded on the page. It checks for YouTube iframes and links and adds additional links to alternative YouTube mirrors such as Yewtu.be, Invidious, etc.
7. Image URL Handling
It adjusts image URLs from Twitter and Reddit to ensure they are displayed correctly:
- For Twitter images, it removes unnecessary query parameters.
- For Reddit preview images, it converts them to direct image links.
8. Cursor Position Management
When replacing URLs in text input fields or editable areas, the script saves and restores the cursor position to maintain user convenience.
9. Throttling and Periodic Adjustments
To optimize performance, certain functions like adjusting iframe heights are throttled to run at most once every few seconds.
How It Works
- Initialization:
- The script initializes by setting up event listeners for page load, keydown, and input events.
- It defines regular expressions to match URLs from different social media platforms.
- Link Replacement:
- It iterates through all links on the page and checks if they match any of the defined regular expressions.
- If a match is found, it replaces the link with an iframe embedding the corresponding social media post.
- Dynamic Height Adjustment:
- Each iframe is set up with a MessageChannel to communicate with the embedded content.
- When the embedded content sends a message indicating its height, the script adjusts the iframe's height accordingly.
- Additional Links and Features:
- For Twitter embeds, it adds Twstalker links and other archiving service links.
- For YouTube embeds, it adds mirror links to alternative YouTube services.
- Continuous Monitoring:
- The MutationObserver continuously monitors changes in the document body to handle dynamically loaded content.
