About stupid-NoVNC-copy-paste

stupid-NoVNC-copy-paste is a lightweight JavaScript utility designed to add copy-paste functionality to NoVNC browser-based virtual network computing sessions. It solves the tedious problem of manually typing commands into remote desktop interfaces by allowing users to paste text directly from their clipboard. The script works by simulating keyboard input, enabling right-click paste operations or programmatic string injection via the sendString method. Version 1.5 introduces robust support for special characters such as at signs, hashtags, and dollar signs that require the Shift key, ensuring accurate input for complex passwords and code snippets. It correctly handles case sensitivity to preserve uppercase and lowercase letters and resolves newline issues by mapping escape sequences to actual Enter key presses, including fixes for Windows-style line breaks. Users can customize settings like typing delay, canvas selectors, and logging levels to adapt to network conditions. To use it, simply copy the source cod

stupid-NoVNC-copy-paste 📋 V 1.5

Because sometimes the dumbest solutions are the best! 🚀

Add copy-paste to NoVNC with a ridiculously simple Javascript script. Now with support for special characters, proper case handling, and more configurations.

Why? 🤔

Because having to type everything manually in NoVNC is stupid. And yes, there are probably better ways to do this, but hey, this works!

Quick Start ⚡

Press F12 to open the browser console
Copy the content of index.js
Paste it in the console
Done! Now use right-click to paste text in your NoVNC session

Test Example 🧪

Try copying and pasting this text to test the functionality:

VNCPaste@2025#TestHash$Alew140.dev%

This example includes uppercase, lowercase, and special characters - all should work correctly now!

What's New in this Version 🎉

Finally! Support for symbols that need Shift (@, #, $, etc)
Fixed case handling! Now uppercase and lowercase letters work correctly thanks @SiegfriedSchmidt 🎯
Customizable configuration (in case you want to make it even more stupid)
Better error handling (because things can fail)

Configuration (that we don't need) ⚙️

// Default configuration
const vncPaste = new VNCPaste({
    selector: '#noVNC_canvas',    // Main canvas selector
    fallbackSelector: 'canvas',   // Fallback selector if main fails
    delay: 50,                    // Typing speed (ms)
    enableLogging: true,          // To see what the hell is happening
    rightClickEnabled: true       // In case you prefer using vncPaste.sendString('text here')
});
vncPaste.init();

// Or if you want to be more specific:
const vncPasteCustom = new VNCPaste({
    selector: '#mySpecialCanvas',
    delay: 100,                   // Slower for slow connections
    enableLogging: false,         // Silent mode
    rightClickEnabled: false      // Disable right-click
});
vncPasteCustom.init();

Known Issues 🐛

Sometimes fails with some special characters (or maybe I already fixed it)
It's not the most elegant solution in the world (but you already knew that)
There are probably better ways to do this
Typing doesn't cost that much
Pasting a script from a stranger in your console doesn't sound like a good idea

What's New in V1.5 🚀

Fixed Newline Handling: \n now actually presses Enter! No more single-line disasters.
Windows Support: Fixed the double-enter issue with \r\n. We strip the \r because we don't need that negativity in our lives.
Manual Testing Guide: Added tips for the brave souls who type commands manually.

Manual Testing (For the brave/bored) 🤠

If you are manually typing sendString in the console because you like typing:

\n = Presses Enter (New line)
\\n = Types \n literally (like for echo -e)

// Example: Press Enter after typing 'ls' (Executes the command)
vncPaste.sendString('ls\n');

// Example: Type a literal \n (Good for echo commands)
vncPaste.sendString('echo -e "\\nLine 1\\nLine 2 \\nLine 3"');

So if your echo command executes in 3 separate lines, it's because you forgot to escape the backslash. That's on you. 🤷‍♂️

Bug Fixes in V1.3 🔧

Fixed case inversion bug: Previously, uppercase letters were being typed as lowercase and vice versa. Now "VNCPaste" stays "VNCPaste"! ✨
