@pyscript/core

We have moved and renamed previous core module as polyscript, which is the base module used in here to build up PyScript Next, now hosted in this folder.

Documentation

Please read core documentation to know more about this project.

Development

Clone this repository then run npm install within its folder.

Use npm run build to create all artifacts and dist files.

Use npm run server to test locally, via the http://localhost:8080/tests/ url, smoke tests or to test manually anything you'd like to check.

Artifacts

There are two main artifacts in this project:

• stdlib and its content, where src/stdlib/pyscript.js exposes as object literal all the Python content within the folder (recursively)
• plugins and its content, where src/plugins.js exposes all available dynamic imports, able to instrument the bundler to create files a part within the dist/ folder, so that by default core remains as small as possible

Accordingly, whenever a file contains this warning at its first line, please do not change such file directly before submitting a merge request, as that file will be overwritten at the next npm run build command, either here or in CI:

// ⚠️ This file is an artifact: DO NOT MODIFY

Running tests

Before running the tests, we need to create a tests environment first. To do so run the following command from the root folder of the project:

make setup

This will create a tests environment [in the root of the project, named ./env]and install all the dependencies needed to run the tests.

After the command has completed and the tests environment has been created, you can run the integration tests with the following command:

make test-integration

pyscript python package

The pyscript package available in Python lives in the folder src/stdlib/pyscript/.

All Python files will be embedded automatically whenever npm run build happens and reflected into the src/stdlib/pyscript.js file.

It is core responsibility to ensure those files will be available through the Filesystem in either the main thread, or any worker.

JS plugins

While community or third party plugins don't need to be part of this repository and can be added just importing @pyscript/core as module, there are a few plugins that we would like to make available by default and these are considered core plugins.

To add a core plugin to this project you can define your plugin entry-point and name in the src/plugins folder (see the error.js example) and create, if necessary, a folder with the same name where extra files or dependencies can be added.

The build command will bring plugins by name as artifact so that the bundler can create ad-hoc files within the dist/ folder.
