a simple library for converting a filepath to a disguise asset object.

type-safety is included out of the box.

Disguise asset object?

Disguise (aka d3) uses a set of content management rules to manage version replacements and other magic under the hood of their media server. This library attempts to recreate the logic they use to process a file based on it's file name and path. The resulting object looks like:

interface DisguiseAsset {
	stem: string
	extension: string
	version?: string
	proxyLevel?: number
	frameStart?: number
	originalFilename: string
}

you might notice that version is a string, when all other tags are numbers, and that's because date+letters is also a valid version tag. Versions are always sorted alphabetically.
