Emacs-ng is an experimental fork of GNU Emacs that aims to modernize the traditional editor by introducing native features such as asynchronous execution, dynamic modules, and integration with advanced technologies like WebAssembly and JavaScript engines. It builds upon the extensibility of Emacs while addressing some of its long-standing performance and architectural limitations. One of its key innovations is the ability to run JavaScript code within Emacs using embedded engines, enabling new forms of interaction and extension development. Emacs-ng also explores concurrency improvements, allowing certain tasks to execute asynchronously without blocking the editor’s main thread, which enhances responsiveness. ...
