api

a single use api is exposed where you can define "programs" for the shell. exec() is program's entrypoint and setup() is like its getopts.

"cash-money" modifies "cash" to accept async exec()s but you still need to make sure exec()s are executed serially asynchronously.

meaning that you cannot call cash commands in the middle of each other. there is no threading or process management.

do a waterfall await cash(<thing 1>); await cash(<thing 2>); and you are good with no race conditions.

const { console: logger, cash, use } = require("react-ode-cash-money");
// this works if you call before 1st execution
use({
  // program's binary name
  name: "sample",
  // help when executed as "help <command>"
  help: "sample help",
  // program's entry point
  exec: async function (argv) {
    // application logic goes here
    if (argv.version) {
      logger.log("Sample 1.0.0"); // or import console from cash-money
      return 0;
    }
  },
  // program's command line parser setup
  setup: function (vorpal, interfacer, preparser) {
    vorpal
      .command("sample")
      .parse(preparser)
      .option("-v, --version", "show version")
      .action(function (args, callback) {
        // this call glues vorpal to cash basically
        return interfacer.call(this, args, callback);
      });
  },
});
// this is how you use the new command:
(async () => {
  console.log(await cash(`sample --version`));
  console.log(await cash(`help sample`));
})();
