Support multi-episode torrents?

[FezVrasta]

Thanks for the library!

I need to extract the episodes contained into a single torrent name, for example:

Marvel\'s.Agents.of.S.H.I.E.L.D.S02E01-03.Shadows.1080p.WEB-DL.DD5.1

This should, ideally, return as season an array like [1, 2, 3], but right now it returns just 1.

I use this RegExp in my own code right now but I think it would make sense to have this built into the library:

/[Eex]([0-9]{2})(?:\-)?([0-9]{2})?(?:[^0-9]|$)/g

// result: 1, 3 - which can then be used to infer the episodes in the middle of the sequence

Hello!
Indeed multi episode release names does not work currently with this library.
Thank you for your RegExp, I will use it to integrate the feature soon. Right now it does not work because the structure of the regex handlers returns only the first match. But I will look into a way to make it more capable.
Have a good day

FYI the ugly regex used by sonarr (C# project) to handle this case :

//Multi-episode Repeated (S01E05 - S01E06, 1x05 - 1x06, etc)
                new Regex(@"^(?<title>.+?)(?:(?:[-_\W](?<![()\[!]))+S?(?<season>(?<!\d+)(?:\d{1,2}|\d{4})(?!\d+))(?:(?:[ex]|[-_. ]e){1,2}(?<episode>\d{1,3}(?!\d+)))+){2,}",
                          RegexOptions.IgnoreCase | RegexOptions.Compiled),

                //Episodes with a title, Single episodes (S01E05, 1x05, etc) & Multi-episode (S01E05E06, S01E05-06, S01E05 E06, etc) **
                new Regex(@"^(?<title>.+?)(?:(?:[-_\W](?<![()\[!]))+S?(?<season>(?<!\d+)(?:\d{1,2}|\d{4})(?!\d+))(?:[ex]|\W[ex]|_){1,2}(?<episode>\d{2,3}(?!\d+))(?:(?:\-|[ex]|\W[ex]|_){1,2}(?<episode>\d{2,3}(?!\d+)))*)\W?(?!\\)",
                          RegexOptions.IgnoreCase | RegexOptions.Compiled),

//Multi-episode release with no space between series title and season (S01E11E12)
                new Regex(@"(?:.*(?:^))(?<title>.*?)(?:\W?|_)S(?<season>(?<!\d+)\d{2}(?!\d+))(?:E(?<episode>(?<!\d+)\d{2}(?!\d+)))+",
                          RegexOptions.IgnoreCase | RegexOptions.Compiled),

                //Multi-episode with single episode numbers (S6.E1-E2, S6.E1E2, S6E1E2, etc)
                new Regex(@"^(?<title>.+?)[-_. ]S(?<season>(?<!\d+)(?:\d{1,2}|\d{4})(?!\d+))(?:[-_. ]?[ex]?(?<episode>(?<!\d+)\d{1,2}(?!\d+)))+",
                          RegexOptions.IgnoreCase | RegexOptions.Compiled),

//4 digit episode number
                //Episodes with a title, Single episodes (S01E05, 1x05, etc) & Multi-episode (S01E05E06, S01E05-06, S01E05 E06, etc)
                new Regex(@"^(?<title>.+?)(?:(?:[-_\W](?<![()\[!]))+S?(?<season>(?<!\d+)\d{1,2}(?!\d+))(?:(?:\-|[ex]|\W[ex]|_){1,2}(?<episode>\d{4}(?!\d+|i|p)))+)\W?(?!\\)",
                          RegexOptions.IgnoreCase | RegexOptions.Compiled),

We are lucky that naming groups will be in ES2018 so there will no big problem to reuse this code ^^
