Cassette Futurism Theme

  • Analog Dream: Beige Terminal - light vintage workstation colors with deep retro accents.

  2. Run zed: install dev extension.
  3. Select this repository directory.
  4. Select either Cassette Futurism theme from Zed's theme picker.

Marketplace Readiness

This repository is structured as a standalone Zed theme extension:

  • extension.toml is at the repository root.
  • Theme JSON lives in themes/cassette-futurism.json.
  • The theme file declares the official https://zed.dev/schema/themes/v0.2.0.json schema.
  • The extension id is cassette-futurism-theme, which is suitable for the Zed extensions registry.
  • LICENSE is present at the repository root.

To publish it in the Zed extension marketplace after the public GitHub repository exists, add it to zed-industries/extensions:

git clone https://github.com/zed-industries/extensions
cd extensions
git submodule add https://github.com/taotao7/cassette-futurism-theme extensions/cassette-futurism-theme

Then add this entry to extensions.toml:

[cassette-futurism-theme]
submodule = "extensions/cassette-futurism-theme"
version = "0.0.1"

Run pnpm sort-extensions, commit the change, and open a pull request.

Development

The source palette is palette.toml. Regenerate the Zed theme file after changing colors:

python scripts/generate_theme.py
python scripts/generate_theme.py --check
python -m json.tool themes/cassette-futurism.json > /tmp/cassette-futurism.json
