The built in terminal is fast. However when you first install it enables AI, auto-completion and other helpful features that I don't want.</p><h1>My zed configuration</h1><p>This is a way to globally turn off these features.</p><p>~/.config/zed/settings.json</p><pre><code>{
"disable_ai": true,
"show_completions_on_input": false,
"show_edit_predictions": false,
"disable_ai": true,

"theme": {
"mode": "dark",
"light": "Ayu Light",
"dark": "GitHub Dark Default"
}
}</code></pre><p>Turning "format_on_save" off is essential for elixir development. By default zed will remove the semi-colons from the start of atoms whenever you save a file 😱!</p>elixir koanshttps://hedgehogai.codeberg.page/elixir-koans.htmlhedgehog-aihedgehog-ai@use.startmail.com2025-12-02T09:00:00Z<p>Koans are a great way to practice test driven skills and learn by doing. <a href="https://github.com/elixirkoans/elixir-koans">elixir-koans</a> is a nice repo to learn Elixir syntax by getting tests to pass. You can try doing 10 minutes a day or solve them all in one go if your that way inclined 💪.</p><h1>Install</h1><pre><code>git clone https://github.com/elixirkoans/elixir-koans

brew install rlwrap
# Run Guile with readline support
rlwrap guile
# Or create an alias in ~/.zshrc:
echo 'alias guile="rlwrap guile"' >> ~/.zshrc
