On the command line

scmjs is scmJS in a terminal: it reads, checks, changes and shares maps and replays without the editor's window. It needs Node.js 22.12 or newer. Run it without installing:

npx @scm-js/cli info "(2)Ridge.scx"

or install it once with npm install -g @scm-js/cli and type scmjs from then on. The commands that draw a map or run the game read your StarCraft folder directly, so they need no extracted graphics. The command line guide has the rest.

Without Node, each release also has scmjs as a single program with Node inside it: scmjs-cli-windows-x64.zip, scmjs-cli-macos-arm64.tar.gz, scmjs-cli-macos-x64.tar.gz and scmjs-cli-linux-x64.tar.gz on the releases page. Unpack it and put scmjs (scmjs.exe on Windows) in a folder on your PATH, or install it with scoop install scmjs (after scoop bucket add scm-js https://github.com/scm-js/scoop-bucket), winget install scm-js.scmjs or brew install scm-js/tap/scmjs. Like the app it is not code-signed, so Windows and macOS ask once before running it: see Without Node.
