Leave and re-enter asciimatics mode?

Hi @peterbrittain –

Is there a way to leave and re-enter asciimatics mode? I.e., to close and reopen the Screen?

Use case: To open a pdb session at some point in my program and inspect the state, ideally with the ability to continue the program afterwards.

It is possible using the Screen.open() and Screen.close() methods, but as you can see in the docs, that means you have a new screen object after the open call and so need to plumb that through to the rest of your code.

I guess you could make use of the existing logic to resize and throw a new exception that you catch in the main loop, close the screen and invoke the debugger, but you will lose some program state. I typically use logging rather than pdb for this reason.

That works great, thank you! (In my case, the view containing the Screen is stored in a global variable anyway so it's no issue to update it.)
