demo-cli is a simple javascript class that allows you to create neat-o canned demos of CLI-based tools.

          import DemoCLI from "./demo-cli.js"

          const cli = new DemoCLI("#simple")

          const h = (async () => {
            cli.printPrompt()
            await cli.type('echo "testing this"')
            cli.enterKey()
            cli.println("testing this")
            cli.printPrompt()
          })()
        

          import DemoCLI from "./demo-cli.js"

          const cli = new DemoCLI("#cli")
          cli.printPrompt()
          cli.print("print ")
          cli.print("on same line ")
          cli.enterKey()

          let colorNum = 1
          for(let x = 0; x <= 16; x++) {
            cli.printPrompt()
            cli.println("colors", {className: `base0${x.toString(16)}`})
            colorNum++
          }

          cli.println("println")
          cli.println("println")
          cli.printPrompt({className: "base08"})
        

          import DemoCLI from "./demo-cli.js"
          const t = new DemoCLI("#typing-cli")
          const f = (async () => {
            while (true) {
              t.printPrompt()
              await t.type("here I am typing", {delay: 60, random: true})
              t.enterKey()
              t.printPrompt()

              await t.wait(2000)

              await t.type("here I am typing more stuff")
              t.enterKey()
              t.printPrompt()

              await t.type("going to reset here")
              await t.wait(2000)
              t.enterKey()
              t.reset()
            }
          })()
