Ability to add logic inside widget #6072
Description
One of the most important things holding textual back right now is the ability to do python logic inside a widget.
For example, I want to make a repl in textual. As far as I know this is completely impossible without hundreds of lines of code. Where as in plain python you can do this
while True:
x = input("?: ")
print(x)It would be nice to then just take that while loop and just have a widget that can run that code. Like a container widget that just keeps that output prompt inside of the widget. For example:
def run_code():
pass
class Myapp(App):
def compose():
yield CodeContainer(func=run_code)This would make it so much easier to write things like REPLs and things that have to respond to user input.
