Rust in Peace

A dark theme for VS Code, inspired by the album art of Megadeth's 1990 metal masterpiece, Rust in Peace.

Colour Palette

The complete palette, including ANSI terminal colours, lives in src/palette.json — the single source of truth the VS Code theme, its lighter variants, and everything below are generated from at build time.

Hand-picked from the record's rusted, cobalt-blue cover art.

Rust in Peace

Hangar 18

Polaris

Dawn Patrol

Installation

Install straight from the Visual Studio Marketplace, or from inside the editor:

1. Open the Extensions sidebar in VS Code — View → Extensions
2. Search for Megadeth (curse you, rust-lang!!!)
3. Click Install
4. Code → Preferences → Color Theme → Rust in Peace — or one of its lighter variants, Hangar 18 (a subtle lift) and Polaris (lighter still), or Dawn Patrol, the light theme

Companion themes

The VS Code theme isn't the only target. src/palette.json is the single source of truth, and matching themes for other tools are generated from it into ports/. Every target ships all four variants — core, Hangar 18, Polaris, and Dawn Patrol (light) — as separate files, except Zed, whose single file is a theme family carrying all four:

Copy the relevant file into your tool's theme directory, then select rust-in-peace (or a variant slug). Run just build-ports to regenerate them all after a palette change.

Herdr has no standalone theme files — its files are config fragments to merge into ~/.config/herdr/config.toml, recolouring the tokyo-night base theme (tokyo-night-day for Dawn Patrol).

To add another target, drop a generator in scripts/targets/ and register it in scripts/build_ports.py; it reuses the shared palette loader and resolver in scripts/palette.py.

Contributing

To work on the theme:

1. Clone this repo and open it in VS Code
2. Open View → Run
3. Click Launch Extension — this opens a second VS Code window
4. Target scopes with the Developer: Inspect Editor Tokens and Scopes command
5. Edit src/rust-in-peace.yml and run npm run build; changes appear live in the window from step 3

Colours live in src/palette.json; src/rust-in-peace.yml maps them onto VS Code keys via {{group.key}} placeholders. Edit the palette to shift a colour everywhere at once.
