Completely rewrite how subscription validation is performed. Optimizes it quite a bit while also adding backend support for the upcoming `dissect` sub-command, where you can resolve any subscription into its 'raw' form for easier debugging when making scripting changes.
Disallow override variable names conflicting with plugin names.
May cause backward incompatible issues from `date_range` being an old override variable name for the `Only Recent` preset. Update this variable name to `only_recent_date_range` to resolve. More info in https://ytdl-sub.readthedocs.io/en/latest/deprecation_notices.html
Closes https://github.com/jmbannon/ytdl-sub/issues/386
Adds the ability to preserve mtime via Output Options. Usage:
```
output_options:
preserve_mtime: True
```
Thanks @e1ven for the contribution!
With the right functions, it was possible for subscription validation to raise a false-positive error. This should hopefully resolve that issue and give validation a small performance increase
Adds generic `filter_include` and `filter_exclude` plugins in anticipation for function script usage. Will detail it more with official docs at a later time!
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.
