CCRL extensions

The extensions consist of 2 parts:

• A .js script that modifies CCRL live viewer files to query one or more kibitzers and showing/printing their evaluations.
• A .NET backend capable of running those kibitzers locally in the background.

Only one CCRL live viewer tab can be open at a time in the browser for these extensions to work.

This is what it looks like to watch a game with one engine (StockFish 17) as kibitzer with MultiPV set to 3:

How to setup

You can find the frontend script and a few pre-compiled binaries (Windows, Linux, macOS) in the latest release.

Alternatively, you can always build the backend yourself (.NET 8.0 required) and take the script from the repository (src/front/ccrlExtensions.js)

Front end

1. Install a usercript runner. Only tested on both Firefox and Chrome with the userscript managers Violentmonkey and Tampermonkey.
2. Copy ccrlExtensions.js into a new userscript and save changes.

Back end

1. Adjust kibitzer path(s) in appsettings.json to your local engine(s) path(s).
2. Execute the binary (or build and run the project if you're not using a pre-built one).
