When IntelliJ autofills an override for a method, the nullability annotations it chooses may not be from the library you want:

Luckily this can be changed! Though the settings for it are buried a bit.

On the lefthand side, navigate to the menu Editor > Inspections

It turns out OpenFL PreForm 2.3.3 does actually support virtual printers for the Form 1, Form 1+ and Form 2, which allows dumping a print’s .flp files to a local directory.

It is unfortunately disabled in the public build, but it is relatively simple to enable by editing PreForm.exe in a hex editor.

Notes:

This is specifically for the OpenFL 2.3.3 release of PreForm for Windows, found on the OpenFL GitHub page
Make a backup of PreForm.exe! exe files are extremely sensitive to edits, and if done incorrectly PreForm will crash when opened. If that happens, delete the edited PreForm.exe and replace it with your backup copy with the same name! Alternatively, reinstalling PreForm should overwrite the broken copy

1. Obtain a Microsoft Live access token

https://login.live.com/oauth20_authorize.srf?client_id=00000000402b5328&response_type=token&scope=service::user.auth.xboxlive.com::MBI_SSL&redirect_uri=https%3A%2F%2Flogin.live.com%2Foauth20_desktop.srf

Visit the above URL in a browser and log in. You'll be redirected to a blank page. The new URL in the address bar contains a Microsoft Live access token for your account, which is required for Xbox Live authentication.

I've just been pasting them into this CyberChef recipe while testing to get the access_token part out quickly.

Keybase proof

I hereby claim:

I am thenullicorn on github.
I am nllcrn (https://keybase.io/nllcrn) on keybase.
I have a public key ASB7iqVzPvfDtMzsi1aIsMIcvyP04-YGqueBcrOhp35hGgo

To claim this, I am signing this object:

Kotlin's implementations of the algorithms described by Ross N. Williams in his paper, "A Painless Guide to CRC Error Detection Algorithms". See below for a link.

This gist exists solely for the purpose of archive as I learn about CRC algorithms, and I wouldn't recommend these implementations in practice due to my unfamiliarity with them at the time of writing this.

In your file explorer (e.g. Finder):
1. Unzip forge's MDK. This should create a new directory with the same name as the zip.
In a command line / terminal / console:
1. cd /path/to/unzipped/directory
2. ./gradlew setupDecompWorkspace
In IntelliJ IDEA:
1. Select the "Open" button
In older versions this may be labeled "Import" or "Import Project"

	/**
	* Returns a Byte identical to the current one, but with the positions of the least-significant `n`
	* bits reversed, where `n` = [width].
	*
	* This means that the bit at position `0` will be replaced with the value of the bit at position
	* `width - 1`, and vice-versa.
	*
	* Not to be confused with the [invert][Int.inv] function, which toggles all bits in place.
