Voltage

A high-contrast, vibrant dark theme for VS Code (built on top of GitHub Dark Default), plus my personal .bashrc.

No dimming, no washed-out "filter" look — dark background, rich color variety, and clear semantic distinctions between declarations, types, parameters, struct/signal access, and control flow.

What's in this repo

• settings.json — the full VS Code color scheme (token colors + workbench colors)
• .bashrc — personal shell config
• img/ — logo and preview images referenced in this README

Installation

1. Install the GitHub Dark Default theme in VS Code (this is a set of overrides on top of it, not a standalone theme).
2. Copy the contents of settings.json into your VS Code settings.json (Ctrl+Shift+P → "Preferences: Open User Settings (JSON)").
   • If you already have settings in there, merge the keys rather than overwriting the whole file.

For .bashrc, just grab what you need and drop it into ~/.bashrc — not meant to be dropped in wholesale.

Preview

C / CUDA and SystemVerilog:

Tcl:

Python:

These previews are hand-built mockups approximating the real editor rendering, not actual screenshots — useful for a quick look, but worth swapping in real screenshots from your own setup if you want pixel-perfect accuracy.

Language-specific notes

• C/C++: struct/object member access (e.g. x in threadIdx.x) is colored separately from the base identifier.
• SystemVerilog: port declarations (input, output, logic) follow the type/parameter color scheme; struct field access matches the C struct-access color; plain signals default to white.
• Tcl: commands match function color, variables are white, flags/options are orange, control keywords are pink-red.
• Python: and / or / not in conditionals get their own color (see settings.json for the current mapping).

Why keep this in a repo?

VS Code settings usually sync automatically when signed into a personal GitHub account, so this is partly redundant day-to-day. It's here for the cases where that's not true — machines where you're logged into a different account, shared/lab machines, or anywhere you're not signed in at all. .bashrc isn't covered by Settings Sync at all, so it's worth keeping here regardless.

Notes

This is a living theme — colors get adjusted as new languages or edge cases come up. Check the commit history for the latest tweaks.
