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 recent push to 'beautify subscriptions' (see https://github.com/jmbannon/ytdl-sub/releases/tag/2023.10.02), we need the ability to change subscription names from their legacy form:
```
rick_a:
preset:
- "tv_show"
overrides:
tv_show_name: "Rick A"
url: "https://www.youtube.com/channel/UCuAXFkgsw1L7xaCfnd5JJOw"
```
into:
```
tv_show:
"Rick A": "https://www.youtube.com/channel/UCuAXFkgsw1L7xaCfnd5JJOw"
```
This however has implications from ytdl-sub's legacy download archive naming. By default, we write archives to `.ytdl-sub-{subscription_name}-download-archive.json`. If we change the subscription name, the archive will not be found, causing a complete redownload. This new feature gives us the ability to migrate download archives to a new naming schema.
# Migrating to Beautified Subscriptions
## Step 0
BACK UP ALL CONFIG + SUBSCRIPTION FILES!!!!! If something goes wrong, restore your backup and try again and/or ask for help.
## Step 1
Since we know we'll be changing our `subscripion_name` to the value of `tv_show_name`, we can use that in our newly migrated download archive name by setting this within the `tv_show` preset (or whatever your 'base' preset is).
```
presets:
tv_show:
output_options:
migrated_download_archive_name: ".{tv_show_name_sanitized}-download-archive.json"
```
## Step 2
Perform a download as usual, via `ytdl-sub sub ...`. This will load the old archive, and save it into the new archive. You should see `MIGRATION DETECTED` within the logs. Ensure it completes successfully.
Perform another download invocation and ensure you see the `MIGRATION SUCCESSFUL` within the logs.
## Step 3
Now we can set:
```
presets:
tv_show:
output_options:
# rename migrated_download_archive_name to just download_archive_name
download_archive_name: ".{tv_show_name_sanitized}-download-archive.json"
overrides:
tv_show_name: "{subscription_name}"
url: "{subscription_value}"
```
Our download archives now default to our new format, and we set `tv_show_name` + `url` to use subscription values by default.
## Step 4
We can now beautify our subscription.yaml file to:
```
tv_show:
"Rick A": "https://www.youtube.com/channel/UCuAXFkgsw1L7xaCfnd5JJOw"
```
* [BUGFIX] Do not fail with thumbnail issues
* helper
* refactor
* dry-run
* regen fixture
* download arhcive txt -> json in docs, fixtures
* return if no download thumb path
* better test
* more test coverage
