<span class='quote'>Published at 2024-12-15T13:55:05+02:00; Last updated 2024-12-18</span><br />
<br />
<span>I thought it would be fun to have a random Helix theme every time I open a new shell. Helix is the text editor I use.</span><br />
<br />
<a class='textlink' href='https://helix-editor.com/'>https://helix-editor.com/</a><br />
<br />
<span>So I put this into my <span class='inlinecode'>zsh</span> dotfiles (in some <span class='inlinecode'>editor.zsh.source</span> in my <span class='inlinecode'>~</span> directory):</span><br />

<span>So every time I open a new terminal or shell, <span class='inlinecode'>editor::helix::random_theme</span> gets called, which randomly selects a theme from all installed ones and updates the helix config accordingly.</span><br />
