Parse multiple season packs

[Robert Laverty]

A problem I've been tussling with lately is being able to parse the amount of seasons from a magnet's name.

Examples:

s2to 9
s2 and 9
s2 &9
s1-s2
s1 - s2
season2 season 4
season2-4
season 2
season 1, 2, 3, 4, 5 & 6
season 1 2 3 4 5 6
season 1 - 3
season 1 3
season 1-3
season 1 3
seasons 1-3
seasons 1 to 3
3rd season
fresh prince of bel air season 2 3 4 5 6

So far I've come up with this:

export const regex = {
	/** `1st season` */
	nthseason(item: media.Item, slug: string) {
		let matches = slug.match(/\s\d{1,2}[a-z]{2}\sseason\s/gi)
		matches = (matches || []).map(v => v.trim())
		let seasons = matches.map(v => utils.parseInt(v))
		if (seasons.includes(item.S.n)) return true
	},
	/** `season one` */
	season(item: media.Item, slug: string) {
		let nstrs = ['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten']
		let matches = slug.match(
			/\ss(eason)?\s(one|two|three|four|five|six|seven|eight|nine|ten)\s/gi
		)
		matches = (matches || []).map(v => v.trim())
		let nstr = matches.map(v => v.split(' ').pop())[0]
		let index = nstrs.findIndex(v => v == nstr) + 1
		if (item.S.n == index) return true
	},
	/** `seasons 1 - 2` */
	seasons0to(item: media.Item, slug: string) {
		slug = slug.replace(/(through)|(and)|(to)/gi, ' ').replace(/\s+/g, ' ')
		let matches = [
			slug.match(/\s?s(eason(s)?)?\s?\d{1,2}\s?s?(eason)?(\s?\d{1,2}\s)+/gi) || [],
			slug.match(/\s?s(eason)?\s?\d{1,2}\s/gi) || [],
		].flat()
		matches = (matches || []).map(v => v.trim())
		matches = matches.join(' ').split(' ')
		let ints = matches.map(utils.parseInt).filter(v => _.isInteger(v) && v < 100)
		let { min, max } = { min: _.min(ints), max: _.max(ints) }
		if (item.S.n >= min && item.S.n <= max) {
			return max - min + 1
		}
	},
}

It's definitely not very reliable and I was wondering what your input might be.

It looks like guessit can parse some styles

stuff like Life S01-S02 WEBRip 1080p DD5 1 H265-d3g is parsed in the latest version using the tv flag, not sure how far this project would ever go into parsing packs
