Introduction

HoloLayer is a multimedia layer plugin specifically designed for Emacs. It is developed based on PyQt, aiming to significantly enhance the visual experience of Emacs. The plugin provides a series of visual enhancement features, including modern window borders, window jump prompts, cursor animations, window screenshots, transparent floating terminals, and real-time dictionaries, etc. These features not only make the Emacs interface look more modern, but also ensure that the performance of Emacs will not be affected.

Feedback Issues

For other issues, please use the command emacs -q and only add holo-layer configuration for a comparison test. If emacs -q can work normally, please check your personal configuration file.

If the problem still exists under the emacs -q environment, please go here to provide feedback, and attach the content of the *holo-layer* window to submit an issue to us. There are many clues in there that can help us troubleshoot the problem.

If you encounter a crash, please use the following method to collect crash information:

1. First install gdb and turn on the option (setq holo-layer-enable-debug t)
2. Use the command holo-layer-stop-process to stop the holo-layer process
3. Reopen holo-layer, and send the content of *holo-layer* at the next crash
