[PySimpleGUI] How to startup in a repl.it friendly way

[MikeTheWatchGuy]

I'm able to run my programs locally with no trouble.

I'm able to sometimes run my repl.it versions of the same program with no issues.

BUT, I'm finding if I have a browser window open with another repl.it script running, then my scripts have issues. At least I think that's part of the problem.

I also find that the MyApp object's init call is made several times.

Here is my current "start" call:

        remi.start(self.MyApp, title=self.Title ,debug=False, address='0.0.0.0', port=0,  start_browser=True, update_interval=.00001, userdata=(self,))

Here's my repl.it code: https://repl.it/@PySimpleGUI/Design-Pattern-1-One-shot-Window

And here's the errors I got despite it working

Hello @MikeTheWatchGuy ,
I've seen the same problem on repl.it. Now I'm making some tests to make remi working on Heroku.
We can't solve the problem on repl.it without the technical support of the repl's staff.

[MikeTheWatchGuy]

Whew! I'm glad it's not just me!

I took a peek at Heroku. You're fearless! I couldn't make sense of any of it, but I'm not a web guy.

[dddomodossola]

@MikeTheWatchGuy got it working on Heroku https://remitest.herokuapp.com/
I will give you some directions tonight

[MikeTheWatchGuy]

Oh wow! You're SO productive! This is amazing

[dddomodossola]

Here is an heroku "tutorial":

Download Heroku console from here heroku
Open a windows console (cmd) and run the following command "heroku login", then login to heroku
Open the heroku dashboard
Create a new App named pysimpleguitest and click on "Create app"
From the windows console type "heroku git:clone -a pysimpleguitest" and press enter
then "cd pysimpleguitest"
in this folder create a file named "runtime.txt" and write in it python-3.7.2 and save
create another file named "requirements.txt" and write inside the dependencies i.e. "remi"
create your script named my_app.py, here is the content:

import remi.gui as gui
from remi import start, App
import os

class MyApp(App):
    def main(self):
        main_container = gui.VBox(width=300, height=200, style={'margin':'0px auto'})
        return main_container

if __name__ == "__main__":
    heroku_port = int(os.environ['PORT'])
    start(MyApp, address='0.0.0.0', port=heroku_port, start_browser=False)

create a file named "Procfile" without extension and write inside web: python my_app.py

From the windows console type the following commands

git add *
git commit -am "first commit"
git push heroku master
heroku ps:scale web=1
heroku open

let me know if it works for you ;-)

[khink]

Following these steps works. Thanks @dddomodossola !

[dddomodossola]

you are welcome ;-)

[MikeTheWatchGuy]

I never completed getting it working... I've got too many other fixes to put into my code that you've already given me.

[MikeTheWatchGuy]

Oh, I do have a question.... I am unable to run some of my repl.it scripts if it is loaded on another web page. I tried experimenting with the startup settings but didn't find a workaround. As long as it's the only repl.it thing running, It all works great.

[MikeTheWatchGuy]

This one can be closed as I've been working with repl.it folks for any problems I've had on there recently.
