[Discussion] improve Chromium browser portability

[BoringBoredom]

The problem

None of the following popular Chromium browsers are portable in their current manifest forms: Chrome doesn’t support a persistent user directory at all, while Brave and UGC use a custom user directory only in the application shortcut and shim. Opening them by clicking a link in an external application causes them to fall back to the regular user directory.

Extras/bucket/ungoogled-chromium.json

Lines 25 to 31 in 516a5d2

	"shortcuts": [
	[
	"chrome.exe",
	"Chromium",
	"--user-data-dir=\"$dir\\User Data\""
	]
	],

Extras/bucket/brave.json

Lines 30 to 36 in 691fd92

	"shortcuts": [
	[
	"brave.exe",
	"Brave",
	"--user-data-dir=\"$dir\\User Data\""
	]
	],

Extras/bucket/googlechrome.json

Lines 28 to 33 in df64636

	"shortcuts": [
	[
	"chrome.exe",
	"Google Chrome"
	]
	],

The solution

Add a registry file with the following entry to the scripts folder:

https://chromeenterprise.google/policies/#UserDataDir

Configures the directory that Google Chrome will use for storing user data. If you set this policy, Google Chrome will use the provided directory regardless whether the user has specified the '--user-data-dir' flag or not.

[HUMORCE]

In some cases, people just want install alternative browsers instead main browsers via Scoop.

The registry key differs for each browser (for example, Brave). There will be no interference.
In my opinion, Nonportable is the appropriate location for browser manifests that don’t include the policy.
