This Visual Studio Code extension applies a neon glow around each newly typed character, then fades it out gradually. No background color is applied—the glow hovers around the character only, creating a cleaner aesthetic.
Features
Neon Glow Animation
A colored halo appears around the character and fades out in a number of steps.
No Background
The glow is purely around the text—no opaque or semi-transparent background.
Configurable Glow Intensity
Adjust the glow’s brightness (glowIntensity): higher values yield a stronger halo.
Random Colors
Each typed character has a randomly generated color (based on a customizable range).
Auto-Activation
The extension starts automatically once VS Code loads (no manual action required).
Quick Access to Settings
Use the Highlight Character: Open Settings command to jump directly to the extension’s configuration.
Configuration Options
highlightCharacter.steps (default = 10)
The number of steps in the glow fade-out. More steps = longer fade.
highlightCharacter.intervalMs (default = 80)
The interval, in milliseconds, between each step.
highlightCharacter.glowSizePx (default = 20)
The size (in px) of the neon glow (blur radius).
highlightCharacter.glowIntensity (default = 1.0)
The brightness factor of the glow. Increase it for a stronger effect.
highlightCharacter.colorRangeMin (default = 0)
Minimum RGB value (0-255) for random color generation.
highlightCharacter.colorRangeMax (default = 255)
Maximum RGB value (0-255) for random color generation.
Usage
Install this extension and restart VS Code if necessary.
Start typing in any text file: you’ll see the neon glow around your characters.
To customize the effect, open VS Code’s Settings (Ctrl + , on Windows, Cmd + , on Mac) and search for "Highlight Character", or simply use the Command Palette (Ctrl + Shift + P / Cmd + Shift + P) and select "Highlight Character: Open Settings".
