Playlists have always been a pain-point with ytdl-sub. If an author adds new videos to the end of a playlist, as opposed to the front, it breaks ytdl-sub's intuition of incremental scraping by breaking on the first (oldest) video. This update now makes it possible to handle this in the prebuilt TV Show presets:
- Add each URL variable (`url`, `url2`, ...) into the `download` portion of the subscription twice
- First definition is what we all know and use, simply scrapes first-to-last, then downloads last-to-first
- Second definition does the following:
- Check to see if a URL is a YouTube playlist URL, if so...
- Set the field to download, but with modifications to scrape last-to-first, then download first-to-last
- Otherwise...
- Set the field to an empty string, which means ytdl-sub will skip it
Prior PR did not actually work - this actually fixes the bug (https://github.com/jmbannon/ytdl-sub/issues/844) where subscription names would drop periods from them, i.e. Mr. Beast would have the name Beast.
POTENTIAL BREAKING CHANGE
If you have a subscription with a period in its name prior to this fix, this change will make it so your download archive is not found since it uses the subscription name in the download archive file path. To fix, simply change the download archive JSON's name to have the actual subscription name, and not the dropped-period one.
A complete gutting of the internals of ytdl-sub to support functions in our variable syntax, in addition to being able to access a yt-dlp entry's .info.json fields using functions. Functionally, ytdl-sub should still look and behave the same from a user-perspective.
With so many lines of code changed (+8927, -2708), no doubt there will be new issues. Please make a GH issue or reach out on Discord if your config/subscriptions break in any way/shape/form.
Details on how to use function support will come soon in the form of proper documentation in our readthedocs.
Provides options to make ytdl-sub look more 'human-like' to protect from throttling. For range-based values, a random number will be chosen within the range to avoid sleeps looking scripted.
Usage:
```
throttle_protection:
sleep_per_download_s:
min: 2.2
max: 10.8
sleep_per_subscription_s:
min: 9.0
max: 14.1
max_downloads_per_subscription:
min: 10
max: 36
subscription_download_probability: 1.0
```
* actually working
* changed plugin format. Need unit tests, documentation, update e2e to filter
* refactor plugin name, matching now working
* description work in progress, need more intricate testing
* tests looks good, regenerate output
* e2e tested, need more failure tests, no dupe variable names, add docs
* unit tests passing again
* more fail tests
* updated with name, default, better docs
* sanitized vars created
