Installation

From VS Code Marketplace

ext install robbyfuu.robbydev-theme

From Open VSX (Cursor, VSCodium, Theia)

ext install Robbyfuu.robbydev-theme

Or open the Extensions panel, search RobbyDev, click Install.

Activate

Cmd+K Cmd+T (macOS) or Ctrl+K Ctrl+T (Windows/Linux), then pick:

RobbyDev
RobbyDev Black
RobbyDev Mirage

Neon Dreams (optional glow effect)

Each token in the editor emits a soft halo in its own color — purple keywords glow purple, lime strings glow green, cyan types glow cyan. The cursor and active borders pulse in RobbyDev magenta.

⚠️ Disclaimer. Editors like VS Code and Cursor don't natively support runtime CSS injection. The glow works by patching the editor's workbench.html in your install directory. The editor will mark itself as "corrupted" on next launch — this is normal and dismissible. Each editor update reverts the patch; just re-run the enable command. Use at your own risk.

Enable

Set your active theme to any RobbyDev variant.
Open the command palette (Cmd+Shift+P / Ctrl+Shift+P).
Run RobbyDev: Enable Neon Dreams.
Restart the editor when prompted.

On Windows, run the editor as administrator the first time. On macOS/Linux, your editor must be installed in a location you have write access to.

Disable

Command palette → RobbyDev: Disable Neon Dreams → restart.

Configure brightness

Add to your settings.json:

{
  "robbydev.neonBrightness": 0.45,
  "robbydev.disableGlow": false
}

Setting	Type	Default	Effect
`robbydev.neonBrightness`	`0`–`1`	`0.45`	Glow intensity
`robbydev.disableGlow`	boolean	`false`	Keep chrome polish but turn off the heavy text-shadow

Re-run Enable Neon Dreams after changing settings.

Removing the "corrupted" warning (optional)

The patch modifies a core file, so VS Code shows a one-time corruption warning at startup. You can either dismiss it or install the Fix VSCode Checksums extension and run Fix Checksums: Apply.

Recommended Pairing

Pair with a font that has italic ligatures for the best look:

Monaspace Radon (handwriting italics — used in screenshots)
Operator Mono
JetBrains Mono
Fira Code
