pygbag 0.1.5

PyGame wasm for everyone

pygbag

PyGame wasm for everyone ( packager + test server )

"your_game_folder" must contains a main.py and its loop must be async aware eg :

import asyncio
import pygame

pygame.init()
pygame.display.set_mode((320, 240))
pygame.display.set_caption("TEST")


async def main():
    count = 3

    while True:
        print(f"""

        Hello[{count}] from Pygame

""")
        pygame.display.update()
        await asyncio.sleep(0)  # very important, and keep it 0

        if not count:
            pygame.quit()
            return
        count = count - 1

asyncio.run( main() )

# do not add anything from here
# asyncio.run is non block on pygame-wasm


usage:

    pip3 install pygbag --user --upgrade
    pygbag your_game_folder

command help:

    pygbag --help your_game_folder

eg

user@pp /data/git/pygbag $ python3.8 -m pygbag --help test
 *pygbag 0.0.9*

Serving python files from [/data/git/pygbag/test/build/web]

with no security/performance in mind, i'm just a test tool : don't rely on me
usage: __main__.py [-h] [--bind ADDRESS] [--directory DIRECTORY] [--app_name APP_NAME] [--cache CACHE] [--package PACKAGE] [--version VERSION] [--build] [--archive] [--main MAIN] [--icon ICON] [--cdn CDN]
                   [--template TEMPLATE] [--ssl SSL] [--port [PORT]]

optional arguments:
  -h, --help            show this help message and exit
  --bind ADDRESS        Specify alternate bind address [default: localhost]
  --directory DIRECTORY
                        Specify alternative directory [default:/data/git/pygbag/test/build/web]
  --app_name APP_NAME   Specify user facing name of application[default:test]
  --cache CACHE         md5 based url cache directory
  --package PACKAGE     package name, better make it unique
  --version VERSION     package name, please make it unique
  --build               build only, do not run test server
  --archive             make build/web.zip archive for itch.io
  --main MAIN           Specify main script[default:main.py]
  --icon ICON           package name, please make it unique
  --cdn CDN             web site to cache locally [default:https://pygame-web.github.io/pygbag/]
  --template TEMPLATE   index.html template
  --ssl SSL             enable ssl with server.pem and key.pem
  --port [PORT]         Specify alternate port [default: 8000]

Now navigate to http://localhost:8000 with a modern Browser.

v8 based browsers are preferred ( chromium/brave/chrome ... ) because they set baseline restrictions on WebAssembly loading. using them while testing ensure proper operation on all browsers.

NOTES:

• first load will be slower, because setting up local cache from cdn to avoid useless network transfer for getting pygame and cpython prebuilts.

• each time changing code/template you must restart pygbag your_game_folder but cache is not destroyed.

• if you want to reset prebuilts cache, remove the build/web-cache folder in your_game_folder
