Emacs: Why the Top Bar Doesn't Follow the System Theme in Fedora

Emacs is a popular text editor that offers a wide range of features and customization options. However, one common issue that Fedora users face is that the top bar in Emacs doesn't follow the system theme. In this article, we'll explore the reasons behind this issue and provide some possible solutions.

Why Doesn't the Emacs Top Bar Follow the System Theme in Fedora?

The Emacs top bar not following the system theme in Fedora is due to the way Emacs handles theming. Emacs uses its own theming engine called custom-theme-load which doesn't integrate with the system theme by default. This is because Emacs is designed to be cross-platform and doesn't rely on the system theme to maintain consistency across different operating systems.

Possible Solutions

There are a few possible solutions to this issue. Here are some of them:

• Use a Custom Emacs Theme: Emacs offers a wide range of custom themes that you can use to change the appearance of the top bar. You can find these themes by searching for "Emacs themes" in your web browser. Once you've found a theme you like, you can install it by following the instructions provided by the theme's author.
• Use the global-set-key Function: You can use the global-set-key function to change the color of the top bar. Here's an example of how to do this:
  (global-set-key (kbd "C-c t") (lambda () (interactive) (set-face-background 'mode-line "#333333") (set-face-foreground 'mode-line "#ffffff")))

  In this example, C-c t is the key binding for changing the color of the top bar. You can replace this with any key binding you prefer. The #333333 and #ffffff values represent the color codes for the background and foreground colors, respectively.

• Use the color-theme-engine Package: The color-theme-engine package provides a way to integrate Emacs with the system theme. You can install this package by adding the following line to your Emacs configuration file:
  (require 'color-theme-engine)

  Once you've installed this package, you can use the color-theme-select function to choose a theme that matches your system theme.

The Emacs top bar not following the system theme in Fedora is a common issue that can be easily solved by using a custom Emacs theme, changing the color of the top bar using the global-set-key function, or using the color-theme-engine package. By following the steps outlined in this article, you can customize the appearance of the Emacs top bar to match your personal preferences.
