mposcli 0.5.0

CLI helper for MicroPythonOS: https://github.com/MicroPythonOS/MicroPythonOS

mposcli

Experimental CLI helper for MicroPythonOS: https://github.com/MicroPythonOS/MicroPythonOS

Main Idea: Install it via pipx (see below) and use mposcli command in MicroPythonOS repository path.

Install, e.g.:

sudo apt install pipx

pipx install mposcli

To upgrade an existing installation: Just call: pipx upgrade PyHardLinkBackup

Usage e.g.:

cd ~/MicroPythonOS
~/MicroPythonOS$ mposcli run-desktop

CLI

usage: mposcli [-h] {build,cp,cp-app,flash,run-desktop,update,update-submodules,version}
