[New Tracker] Erai-Raws

[6cUbi57z]

Resolves #4116

As on the issue, there is a problem with this in that Erai-Raws isn't really an indexer but is a release site. As such, it has no search, no stats such as files, size, seeders, leechers and the implementation has to work based on the RSS feed (to work reliably) which has limited results. Also the releases don't follow the usual naming conventions on indexers so are not easily detected by Sonarr.

I have managed to put this together which seems to work fairly well but this is rather different to most other indexers (exc. ShowRSS). Like ShowRSS, it is grabbing all items from the RSS feed and then performing a basic filter within Jackett. I also added an option which will try to extract the season and episode numbers from the title and move them to the end in the format S1E1 so that they are detected by Sonarr. It may need another option to exclude the quality tag from the search as searching for episode "10" is also matching "1080p".

...but I'm unsure if it's a good idea to put this in given it's so different. Open to other suggestions if there are better ways to implement it.

Hi @6cUbi57z,

Thanks for your contribution to Jackett!

If you are adding a new indexer, please ensure that you've added it to the readme as well

A human will be along soon to review

Apologies for taking so long to look at this.

Noticed an issue in the title detail parsing, where it seems to be taking any two numbers and making them into SxExx, e.g. Yuukoku no Moriarty Part 2 – 02 (Multi) becomes Yuukoku no Moriarty Part – (Multi) S2E02. That might be a bit of an edge case, but maybe put an exception in for part x?

It could be useful to also move the quality at the end, so instead of [1080p] blahblah - 01 it becomes something like blahblah - E01 - 1080p.

The size, seeds, leechers, DL factor, and UL factor should all be given generic values, so 512MB, 1, 1, 0, and 1 respectively (you can find these defaults here even though it's for YAML indexers). An example of them being used in a C# indexer:

Jackett/src/Jackett.Common/Indexers/ShowRSS.cs

Lines 105 to 109 in f22f37e

	Size = 0,
	Seeders = 1,
	Peers = 2,
	DownloadVolumeFactor = 0,
	UploadVolumeFactor = 1

(just realising ShowRSS' size also gives 0B, that needs changed)

If you want to give yourself more work you could make the generic files sizes different depending on the quality, e.g. 512MB for 720p releases and 1GB for 1080p releases, etc., or whatever is more suitable (increments of 256MB is probably as accurate as you need to be).

No problem. Great feedback.

Seems it was matching on the last season search regex where it checks for " - ". I've added a check before this for " Part - " so it should detect this now as season numbers. Not ideal as I expect there are some anime where "Part 2" is not actually season 2 but I expect there will be a few edge cases like this which is why it can be disabled.

It could be useful to also move the quality at the end, so instead of [1080p] blahblah - 01 it becomes something like blahblah - E01 - 1080p.

Good point. Sorting by name won't work correctly with it at the front. I've moved it to the end. Seemed sensible and fairly safe to do this even with title parsing off. While I was changing this, I also adjusted it so that the search string doesn't apply to the quality. This means that searching for episode "10" of something won't return everything which is 1080p.

Fixed in both Erai-Raws and ShowRSS.

Done. Most seem to have at most 540p, 720p and 1080p so I just checked 3 of the releases and put those sizes as the estimates. It will be wildly inaccurate for batch releases but should be fine for single releases.

Sorry if you had already looked through the code, I ended up refactoring quite a lot for the quality and title parsing stuff.

Thanks for the contribution, looks good and is working here.

I changed peers to 2, as it seems Jackett subtracts 1 from whatever is returned. Not entirely sure why (maybe removing your own potential footprint from the count, which doesn't really make sense to me as you won't be leeching many if any yet), but ShowRSS has the same and it works, so 🤷

what is erairawstests.cs ?

what is erairawstests.cs ?

Unit tests currently only for the title parsing. Debugging the title parsing required titles with certain naming (e.g. "Part 2" above) to appear in the titles which were returned. Adding some tests made this easier to debug and develop.
