As the title stays, the main goal of the branch is to kill the infamous runtimeLoaded global store and all the complications, problems and bugs caused by the fact that in many places we needed to ensure/wait that the global runtime was properly set before being able to execute code. The core idea is that runtime is never a global object and that it's passed around explicitly, which means that when a function receives it, it is guaranteed to be initialized&ready. This caused a bit of complications in pybutton.ts, pyinputbox.ts and pyrepl.ts, because they indirectly want to call runtime.run from connectedCallback, which is the only place where we cannot explicitly pass the runtime because it's automatically called by the browser. But also, it is also a sign of a bad design, because it were entirely possible that connectedCallback was called before the runtime was ready, which probably caused many bugs, see e.g. #673 and #747. The solution to is use dependency injection and create the class later on: so instead of having a global PyButton class which relies on a global runtime (whose state is uncertain) we have a make_PyButton function which takes a runtime and make a PyButton class which is tied to that specific runtime (whose state is certainly ready, because we call make_PyButton only when we know that the runtime is ready). Similar for PyInputBox and PyRepl. Other highlights: thanks to this, I could kill the also infamous runAfterRuntimeInitialized and a couple of smelly lines which used setTimeout to "wait" for the runtime. While I was at it, I also called a lot of other stores which were completely unused and where probably leftovers from a past universe.
PyScript Demonstrator
A simple webapp to demonstrate the capabilities of PyScript.
Getting started
-
If you don't already have Node.js, install it. The official installer for the LTS version of Node is available from nodejs.org.
-
If you don't already have Rollup, install it. Rollup can be installed as a global resource using:
$ npm install --global rollup -
Install the demo apps requirements:
$ npm install -
Start the server:
$ npm run devThis will compile the resources for the app, and start the development server.
-
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. This will provide a list of demos that you can run.
