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.
To be used later for advanced presets. For subscriptions in the form of (+ as prefix)
```
+ Subscription Name:
Music Videos:
- "https://url1.com/..."
Concerts:
- "https://url2.com/..."
```
Stores all the contents under the subscription name into the override variable
``subscription_map`` as a Map value. The above example is stored as:
```
{
"Music Videos": [
"https://url1.com/..."
],
"Concerts: [
"https://url2.com/..."
]
}
```
Advanced scripting is needed to dissect this Map variable into a usable preset

Removes the deprecated `__value__` field in the subscriptions file (different from `__preset__` which is NOT deprecated). This was very short-lived, and most likely not used.
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.
Extends the subscription.yaml syntax at the cost of introducing a breaking change.
# New Syntax
## Mix-n-match presets and indent variables
```
# Can mix/match presets and indent override variables.
# Uses presets TV Show, Only Recent and assigns Kids, TV-Y to subscription_indent_1 and _2
TV Show | = Kids | = TV-Y | Only Recent:
"Jake Trains": "https://..."
```
## Subscriptions with list-value support
```
TV Show | = Kids | = TV-Y | Only Recent:
"Jake Trains":
- "https://url.1..." # Assigns to subscription_value and subscription_value_1
- "https://url.2..." # Assigns to subscription_value_2
```
## Subscriptions with override-keys support
```
TV Show | = Kids | = TV-Y | Only Recent:
"~Jake Trains": # the ~ means "all keys underneath get assigned as override variables"
url: "https://url.1..." # Assigns to url
url2: "https://url.2..." # Assigns to url2
```
# Breaking Changes
In the TV show subscriptions example (https://github.com/jmbannon/ytdl-sub/blob/master/examples/tv_show_subscriptions.yaml), it had
```
TV Show Full Archive:
# Sets "Kids" for genre, "TV-Y" for content rating
= Kids | TV-Y:
"Jake Trains": "https://www.youtube.com/@JakeTrains"
"Kids Toys Play": "https://www.youtube.com/@KidsToysPlayChannel"
```
This must be changed to
```
TV Show Full Archive:
# Sets "Kids" for genre, "TV-Y" for content rating
= Kids | = TV-Y: # Each indent variable assignment must have an = before it
"Jake Trains": "https://www.youtube.com/@JakeTrains"
"Kids Toys Play": "https://www.youtube.com/@KidsToysPlayChannel"
```
With the new preset nesting support, `__preset__` would have lower precedence which isn't ideal since it's meant to serve as a 'apply to all presets in this file'. Now the order of priority is:
`inherited presets (top-to-bottom) -> preset itself -> nested subscription presets -> __preset__ -> subscription values`
A follow-up to the prior commit which fixes some bugs in the 'beautiful subscriptions' implementation. A proper migration guide will be written in the wiki once it's ready
Closes Feature Request: https://github.com/jmbannon/ytdl-sub/issues/743
Subscriptions support using presets as keys, and using keys to set override variables as values.
For example:
```
tv_show:
only_recent:
[News]:
"Breaking News": "https://www.youtube.com/@SomeBreakingNews"
[Tech]:
"Two Minute Papers": "https://www.youtube.com/@TwoMinutePapers"
```
Will create two subscriptions named "Breaking News" and "Two Minute Papers", equivalent to:
```
"Breaking News":
preset:
- "tv_show"
- "only_recent"
overrides:
subscription_indent_1: "News"
subscription_name: "Breaking News"
subscription_value: "https://www.youtube.com/@SomeBreakingNews"
"Two Minute Papers":
preset:
- "tv_show"
overrides:
subscription_indent_1: "Tech"
subscription_name: "Two Minute Papers" subscription_value: "https://www.youtube.com/@TwoMinutePapers"
```
You can provide as many parent presets in the form of keys, and subscription indents as ``[keys]``.
This can drastically simplify subscription definitions by setting things you want configurable like so in your
parent preset:
```
presets:
tv_show_name:
overrides:
tv_show_name: "{subscription_name}"
url: "{subscription_value}"
genre: "{subscription_indent_1}"
```
NOTE!!!
Changing your subscription name from 'legacy' subscriptions will need their download archive file migrated to a new name. A future update will assist in this migration process. Either wait until then or, if you consider yourself a ytdl-sub expert, keep a backup of your subscription file before migrating.
