themer

The tool converts a collection of colors into themed assets for a wide range of environments, including code editors, terminal emulators, desktop wallpapers, and communication applications such as Slack. Users provide one or more color sets—either built‑in palettes, custom JavaScript definitions, or Base16 YAML files—along with desired templates, and the program generates matching theme files and visual backgrounds in the specified resolutions.

It is available as a command‑line interface that can be installed from npm, run globally, or invoked via npx without installation. The CLI accepts options for selecting color sets, templates, wallpaper sizes, and output locations, producing all results in a single output directory. A JavaScript API with TypeScript typings is also exposed for programmatic integration.

The project includes a progressive web app for interactive preview, supports any CSS color format in the web UI, and offers built‑in templates for many popular editors and terminals. It is packaged as a single TypeScript/JavaScript distribution, enabling straightforward use and customization.
