For NPM module authors that would like to support Deno but do not want to write and maintain a port.

import * as st from "scripting-tools";

export function execFactory(params: { isDryRun: boolean }) {
    const { isDryRun } = params;

    const exec: (cmd: string) => Promise<void> = !isDryRun
        ? async cmd => {
              console.log(`$ ${cmd}`);
              await st.exec(cmd);
          }
        : cmd => {
              console.log(`(dry)$ ${cmd}`);
              return Promise.resolve();
          };
    return { exec };
}
