tulip web: run UIScreen apps in code editor

[bwhitman]

We just eval the code editor. It should look for a def run()? and run it instead. Or something. But for now, if you paste a UIScreen app in the editor and click the green button it doesn't do anything unless you add a if __name__ == '__main__': thing.

An annoyance here (self-owned) is that def run(screen): overwrites the imported from tulip import run in the namespace when running this type of code. They are two different runs with the same name.

It's just, like, one corporation's styleguide's opinion, but the obvious resolution is to use tulip.run instead of your run.

Is that their style guide for python interpreters that are also the CLI for the entire OS? They think of everything .

I really want to keep things like bare ls and run at the REPL. It's a better fix to rename the run out of UIScreen apps and/or have the web interpreter be somewhat intelligent about what kind of code it's running.

I agree with making run resolve to tulip.run in the REPL.

What about using main() for the main function of the app you're defining in the editor ?

FTR: I think the bare ls etc. are unhappy compromises, because they attempt to bend the syntax of the REPL. I frequently find myself tricked into thinking I'm typing at a terminal shell, then very rapidly am brought back to reality. My preference is to embrace the REPL syntax. Not for nothing was print variable was removed in Python 3.x.
