We're using this fork to make changes to the pxt library, but instead of hosting our own npm package that chibitronics/pxt-microbit pulls in, we are going to use patch-package to manage the changes to the pxt library within chibitronics/pxt-microbit.

So to update pxt in chibitronics/pxt-microbit, clone this repo, and then run this command:

• npm run build

Then go back to the chibitronics/pxt-microbit directory and run these commands:

• cp ../pxt/built/pxt.js node_modules/pxt-core/built/pxt.js
• cp ../pxt/built/pxtsim.js node_modules/pxt-core/built/pxtsim.js
• cp ../pxt/built/web/pxtsim.js node_modules/pxt-core/built/web/pxtsim.js

Then run:

• npx patch-package pxt-core

This will generate a patches/pxt-core+10.3.4.patch file.

In chibitronics/pxt-microbit, package.json runs patch-package on postinstall, which will apply the patched changes after installing the pxt-core node module.
