Custom Themes

>=4.5

Starting from v4.5.0, massCode supports custom themes. You can fully customize the look and feel of the app — UI colors and editor syntax highlighting colors.

How it works

• Themes are stored in ~/.massCode/themes/ as JSON files.
• Both light and dark theme types are supported.
• Theme files are watched in real time — edit the JSON, see the result instantly.

Creating a Theme

You can create a new theme directly from Settings → Themes. A Rose Pine-based template will be generated as a starting point that you can customize to your liking.
