| # todo (headless) |
| |
| Example module that uses Ledger to store internal data. |
| |
| To run the module, run: |
| |
| ``` |
| device_runner --device_shell=dev_device_shell --user_shell=dev_user_shell --user_shell_args=--root_module=example_todo_headless |
| ``` |
| |
| This is a headless module, taking no input and writing the output to stdout. |
| |
| The module keeps a list of todo items in a Ledger page, randomly adds and |
| removes items, and prints the state after each modification. Items generated by |
| each instance are tagged with a unique tag. To observe the application running |
| on multiple devices and synchronizing the state using Ledger, [set up Cloud |
| Sync](https://fuchsia.googlesource.com/ledger/+/HEAD/docs/user_guide.md#Setup) |
| and run the module on each device. |
| |
| Example output: |
| |
| ``` |
