As I am toying around with textual, I am wanting some popup user input to take over. Textual is still pretty new and likely to change quite significantly, so I don't want to overdo the work I put into it, So for now on my personal tuis I am going to shell out to tmux.
The main issue is that when you are in a textual app, it kinda owns the
input. So if you try to run another python function that calls for
it just cant get there. There is a
that covers this, and it might work really well for some use cases, but
many of my use cases have been for things that are pre-built like
copier, and I am trying to throw something together quick.
textual is still very beta
Part of this comes down to the fact that textual is still very beta and likely to change a lot, so all of the work I have done with it is for quick and dirty, or fun side projects.
So the solution that was easiest for me... shell out to a tmux popup.
The application I am working on wants to create new documents using
copier templates. copier has a fantastic cli that walks throught he
template variables and asks the user to fill them in, so I just shell
out to that with
. Make sure that you wait for this process to
finish otherwise there will be bit of jank in your textual app.
async def action_new_post(self) -> None: proc = subprocess.Popen( 'tmux popup "copier copy plugins/todo-template tasks"', shell=True ) proc.wait()
Here is what the running todo application looks like with the copier popup over it.
