The browser provides a secure WASM computing sandbox. Both +interpreters are compiled to web assembly with +[Emscripten](https://emscripten.org/). PyScript core maintainers work closely +with the core maintainers of both MicroPython and Pyodide (and CPython). We +work hard to ensure PyScript works efficiently in browsers on all platforms: +desktop, mobile, or elsewhere. + +Our technical documentation for using this project can be +[found here](https://docs.pyscript.net/). + +PyScript sits on two further projects (both written in JavaScript): + +1. [polyscript](https://github.com/pyscript/polyscript/#readme) - used to + bootstrap WASM compiled interpreters in a browser. +2. [coincident](https://github.com/WebReflection/coincident) - used to simplify + worker based tasks. + +PyScript itself is mostly written in JavaScript. The test suite for JavaScript +is in two parts: automated tests run in [playwright](https://playwright.dev/), +and manual tests you have to run in a browser and check yourself. PyScript also +has a plugin system so third parties can extend its capabilities with +JavaScript. Our built-in core plugins can be found in the `src/plugins` +directory. We describe how to write third party plugins in our +[developer documentation](https://docs.pyscript.net/latest/user-guide/plugins/). + +We provide a `pyscript` namespace containing Python modules for common browser +based APIs and features (i.e. you can `import pyscript` in Python code running +inside PyScript, to access these features). The Python code for the `pyscript` +namespace is in `src/stdlib/pyscript` with the associated test suite in +`tests/python`. The tests use the browser friendly +[uPyTest](https://github.com/ntoll/upytest) test framework for checking Python +code running _within_ PyScript. All the Python tests are run in each each +available interpreter in both the main thread and a web worker (i.e. the +test suite is run four times, accounting for each combination of interpreter +and main/worker context). + +When you create a local build all the automated tests (JavaScript and Python) +are run. + +## Developer Guide + +Full instructions for setting up a working development environment, how to +build PyScript and how to test it can be +[found in our official docs](https://docs.pyscript.net/latest/developers/). + +The short version is: + +- Ensure you have Python, node and npm installed. +- Create a Python virtual environment. +- In the root of this repository `make setup`. +- `make build` to build PyScript. +- As dependencies change over time, `make update` to keep in sync. + +To start using the locally built version of PyScript, you'll need an HTML +page something like this (note the relative paths to assets in the `dist` +directory, in the `` of the document): + +```html + + + + + + Codestin Search App + + + + + + + +``` + +Once set up, you should be able to run the most common activities via the +`make` command: + +``` +$ make + +There is no default Makefile target right now.

-# PyScript Demonstrator
-
-A simple webapp to demonstrate the capabilities of PyScript.
-
-## Getting started
-
-1. If you don't already have Node.js, install it. The official installer for the
-   LTS version of Node is available from [nodejs.org](https://nodejs.org/).
-
-2. If you don't already have Rollup, install it. Rollup can be installed as a
-   global resource using:
-
-       $ npm install --global rollup
-
-3. Install the demo apps requirements:
-
-       $ npm install
-
-4. Start the server:
-
-       $ npm run dev
-
-   This will compile the resources for the app, and start the development server.
-
-5. When the compilation completes, it will display something like:
-
-         Your application is ready~! 🚀
-
-         - Local:      http://localhost:8080
-         - Network:    Add `--host` to expose
-
-       ────────────────── LOGS ──────────────────
-
-   Once this is visible, open a browser at
-   [http://localhost:8080](http://localhost:8080). This will provide a list of
-   demos that you can run.
-
-## More information
-
-There is a forum PyScript where you can discuss the project or ask questions at [https://community.anaconda.cloud/c/pyscript](https://community.anaconda.cloud/c/pyscript)

-Enemy:
-  #collideWith
-    checks collision. Bounces off of walls and other enemies. Kills marios.
-    gets killed by block bonk from below
-
-  Specific enemy behaviors:
-    koopas get replaced with shells
-    shells get kicked if touched from the side, instead of killing
-
-Mario:
-  #collideWith
-    gets expelled from walls, bonks blocks, destroys blocks as big Mario
-    note: collision with blocks is determined by which one is over the center
-      if you're slightly to the side, you slip past it.
-  Crazy-ass sprite shifting if you're in star mode!
-
-
-Item
-  #collideWith
-    item pickup logic
-
-Mushroom
-  #update
-    movement logic for mushrooms
-    get impulse from being block bonked
-      this can be implemented by giving them the appropriate accel
-      just if they overlap a block from the bottom.
-      of course, only AFTER they finish sliding out of the block.
-
-Water levels:
-  make a separate class for water Marios
-    less gravity
-    swimming sprite
-    fireballs are the same
-    jump works when not on the ground
-  different enemies
-
-
-TODO: Make level loader use hashes instead of arrays where possible.
-Should be a free performance gain.
-
-Should also make item deletion less weird.
-
-TODO: Make gravity exist higher up instead of having a magic number.
-Note from the future: Nope. Different objects have different gravity.

-G = nx.Graph()
-nodes = list(range(4))
-G.add_edges_from(zip(nodes[0:-1], nodes[1:]))

-    
This chain graph has the following adjacency matrix:

-    
-
-adj_mat = np.eye(4, k=1)
-print(f"A: {adj_mat}")
-
-        

-    
And imagine that we have a message that lives on the graph:

-    
-            
-message = np.array([1.0, 0.0, 0.0, 0.0])
-print(f"message: {message}")
-            
-        

-    
Try out message passing below by doing any one of the following steps:

-    
message @ adj_mat

-    
message @ adj_mat @ adj_mat

-    
message @ adj_mat @ adj_mat @ adj_mat

-    

-

Micrograd - A tiny Autograd engine (with a bite! :))


-        

-            

-                Micrograd is a tiny Autograd engine created
-                by Andrej Karpathy. This app recreates the
-                demo
-                he prepared for this package using pyscript to train a basic model, written in Python, natively in
-                the browser. 

-            

-        

-        

-            

-                You may run each Python REPL cell interactively by pressing (Shift + Enter) or (Ctrl + Enter).
-                You can also modify the code directly as you wish. If you want to run all the code at once,
-                not each cell individually, you may instead click the 'Run All' button. Training the model
-                takes between 1-2 min if you decide to 'Run All' at once. 'Run All' is your only option if
-                you are running this on a mobile device where you cannot press (Shift + Enter). After the
-                model is trained, a plot image should be displayed depicting the model's ability to
-                classify the data. 

-            

-            

-                Currently the > symbol is being imported incorrectly as &gt; into the REPL's.
-                In this app the > symbol has been replaced with ().__gt__() so you can run the code
-                without issue. Ex: instead of a > b, you will see (a).__gt__(b) instead. 

-            

-            

-                import js; js.document.getElementById('python-status').innerHTML = 'Python is now ready. You may proceed.'
-                
Python is currently starting.  Please wait...

-# Freedom Units!
-
-This is a demo Toga app implementing a Fahrenheit to Celsius converter.
-
-## Initial setup
-
-1. Create and activate a virtual environment:
-
-       $ python -m venv venv
-       $ . ./venv/bin/activate
-
-2. Install the demo requirements:
-
-       $ pip install -r requirements.txt
-
-### Development details
-
-This demo symbolically links the pyscript build generated by the npm server
-(`../build`) into the `./static/pyscript` directory. This symbolic link should
-be restored automatically by git. This also means you'll need to run the main
-pyscript demos at least once before running the server-rendered version of the
-app. If you experience problems loading pyscript, check whether this link
-exists, and the `build/pyscript.js` file has been compiled.
-
-It also includes an vendored experimental version of toga-core, toga-web and
-toga-flask, packaged as wheels in the `./static/wheels` directory. If any changes
-are made to the Toga sources, these vendored resources will need to be updated.
-
-## Web app
-
-This app can be viewed as a Single Page App (SPA); this version of the app is
-linked from the main PyScript demo pages.
-
-It can also be viewed as a server-rendered app. This version of the app is
-delivered by a demo Flask server, serving a version of app at the root URL. To
-run the web demo server:
-
-    $ cd server
-    $ PYTHONPATH=../freedom/src python -m demo
-
-then point your browser at http://localhost:8081/
-
-Enter a value in the "Fahrenheit" input, and click the "calculate" button.
-
-It may take a few seconds for this button to become live; look for the
-"Collecting nodes..." entry in the console log.
-
-## Desktop app
-
-To run this app in development mode:
-
-    $ briefcase dev
-
-To build and run an app bundle:
-
-    $ briefcase run
-
-If you're on an M1 macOS, this will raise an error on first run; if you get this error, run:
-
-    $ briefcase package -p app --adhoc-sign
-
-then re-run `briefcase run`
-
-## iOS app
-
-To run this in the iOS simulator, run:
-
-    $ briefcase run iOS
-
-To run this in the Android simulator, run:
-
-    $ briefcase run android
-
-Note that these builds have extensive requirements that must be installed -
-Xcode for iOS, and the Android SDKs for Android. These are multiple gigabyte
-downloads. Briefcase will detect when these tools aren't available, and either
-prompt you to download them, or perform a download for you. As a result, your
-first build may take up to 20 minutes to complete, depending on the speed of
-your connection.
