Monokai Night C Switcher

A VS Code extension that automatically applies Dark+ (VS2026-style) syntax colors when working in C, C++, or C# files, while keeping the Monokai Night UI everywhere else — sidebar, tabs, statusbar, terminal, all untouched.

How it works

The extension listens for active editor changes. When you switch to a .c, .cpp, or .cs file, it injects editor.tokenColorCustomizations and editor.semanticTokenColorCustomizations into your global settings, overriding the syntax token colors with Dark+ equivalents. When you switch away, it clears them and Monokai Night resumes as normal.

No theme switching, no window reloads — just instant token color overrides.

Features

• Automatic switching based on file type — no manual steps
• Monokai Night UI colors preserved at all times
• Dark+ token colors for C/C++/C# — keywords, types, functions, variables, interfaces, and more
• Semantic highlighting support (requires the C# extension for full interface/type resolution)
• Works with Settings Sync once published

Requirements

• Monokai Night by Fabio Spampinato set as your active theme
• For C#: the C# extension with semantic highlighting enabled

Semantic highlighting

For accurate interface coloring in C#, make sure semantic highlighting is enabled in your settings:

"editor.semanticHighlighting.enabled": true

Without this, the C# language server won't provide token types for interfaces and they'll fall back to textMate scope coloring.
