Async extension to a famous Cmd2 library.
Cmd2 permanently occupies the main thread which is a problem if you plan to receive callbacks on the main thread (e.g., by Bluetooth stack Bleak)
BoolTest is available via pip
:
pip3 install ph4-acmd2
From the local dir:
pip3 install --upgrade --find-links=. .
import asyncio
import ph4acmd2
class CmdLineApp(ph4acmd2.Cmd):
async def main(self):
await self.acmdloop()
print("Cmdloop finished now")
if __name__ == '__main__':
app = CmdLineApp()
loop = asyncio.get_event_loop()
loop.set_debug(True)
loop.run_until_complete(app.main())
We use asyncio.lool.add_reader to read from the stdin and process the commands thus it is not currently possible to ue readline features such as auto-complete or ctrl-r, UP-arrow for previous commands, etc...
Readline occupies main thread in a blocking way, so it is not compatible with runloop model running on the main thread and executing coroutines.
In order to use readline it needs to add async support. A potential workaround could be to access terminal in async way e.g., submit short coroutine monitoring the terminal state to simulate readline library. However, it is not tested.
