⚡ AcePaste — Editor Paste Fix

⭐ If this helped you, please star the repo!

Fix broken Ctrl+V and right-click paste in Ace Editor based coding platforms.

Works on IITM SEEK (seek.study.iitm.ac.in) and any website that uses Ace Editor.

😤 The Problem

Many coding platforms (like IITM SEEK) block the normal browser paste:

• Ctrl+V does nothing
• Right-click → Paste is often disabled too
• onpaste = null tricks don't work

Why? They use Ace Editor — the visible editor is not a real textarea. It uses a hidden textarea.ace_text-input, and the site attaches its own listeners to swallow paste attempts before they ever reach it.

✅ The Solution

AcePaste's content script loads at document_start — before the host page's own script has a chance to attach its paste blocker — and steps in on both Ctrl+V and right-click paste. The clipboard text is then handed off to the Ace API directly:

ace.edit(document.querySelector('.ace_editor')).insert(clipboardText)

Both paths ride the browser's native paste event, so no permission popup is ever shown. A brief clipboard-read fallback kicks in only if a stricter site manages to block the native paste anyway.

✨ Features

• Fixes both Ctrl+V and right-click → Paste
• Insert mode (paste at cursor) or Replace mode (overwrite the whole editor)
• Works even when the Ace editor is embedded inside an iframe
• No permission prompts — uses the browser's native paste event
• Per-site toggle: leave it off everywhere except where you need it
• 100% local, nothing leaves your browser

🛠️ How It Works

Extension ON?
  ├─ OFF → do nothing
  └─ ON → intercept Ctrl+V / right-click paste before the site can block it
           → find Ace Editor (including inside iframes)
           → window.ace.edit(el).insert(text)   [or .setValue() for Replace]
           → silent paste, no permission popup

Uses a MAIN world injected script (injected.js) because Chrome extensions run in an isolated world and cannot see window.ace directly.
