This is a massive commit that restructures a lot of the library. The
primary change is the implementation of a second Bedrock core using
WebAssembly, which performs much better than the existing JavaScript
core. The JavaScript core has been retained as a fallback for browsers
that don't support WebAssembly.
Benchmarking both cores using the numbers benchmark and with all of the
devices stubbed out in the emulator demonstrates a 40x speedup for the
WebAssembly implementation (going from 4800ms to 120ms).
Measure run performance2025-09-07T07:04:41ZBen Bridleben@derelict.engineering2025-09-07T07:04:41Zurn:sha1:4c67a10f265dde1c3aa430cb851062a38646d6f2Improve transmission rendering performance2025-09-07T06:47:51ZBen Bridleben@derelict.engineering2025-09-07T06:46:29Zurn:sha1:53fa574c9af4095f07f4883547939a25522f81e6
Previously, the DOM would be updated every time a complete character
was pushed to the transmission parser by the stream device. This caused
frequent re-renders of the transmission panel and massively slowed down
the emulator.
To fix this, the contents of the transmission parser are now only
flushed to the transmission panel when the state panel updates, which
is currently every 10_000 cycles.
Show assembled bytecode when checking program2025-09-07T06:43:07ZBen Bridleben@derelict.engineering2025-09-07T06:43:07Zurn:sha1:e09013621b3c26945d16d7f2a621bd18f1e814e4
Clicking the CHECK button will open the bytecode panel if the program
assembles successfully, displaying the assembled bytecode.

Click events on touchscreen devices are handled by the touchstart and
touchend events. These events will now enable and disable the pointer
device, move the pointer position, and press and release the primary
pointer button.
Add a nocursor attribute to the <bedrock> element2025-07-04T11:03:52ZBen Bridleben@derelict.engineering2025-07-04T11:03:40Zurn:sha1:8f54cac05765bb47488bec7242bb865a1dc1f7d4
This attribute hides the mouse cursor on the program canvas.
