Subscriptions File
==================
------------------
subscriptions.yaml
------------------
The ``subscriptions.yaml`` file is where we use our :ref:`config_reference/config_yaml:presets` in the :ref:`config_reference/config_yaml:config.yaml`
to define a ``subscription``: something we want to recurrently download such as a specific
channel or playlist.
The only difference between a ``subscription`` and ``preset`` is that the subscription
must have all required fields and ``{override_variables}`` defined so it can perform a download.
Below is an example that downloads a YouTube playlist:
.. code-block:: yaml
:caption: config.yaml
presets:
playlist_preset_ex:
download: "{url}"
output_options:
output_directory: "{output_directory}/{playlist_name}"
file_name: "{playlist_name}.{title}.{ext}"
overrides:
output_directory: "/path/to/ytdl-sub-videos"
.. code-block:: yaml
:caption: subscription.yaml
my_subscription_name:
preset: "playlist_preset_ex"
overrides:
playlist_name: "diy-playlist"
url: "https://youtube.com/playlist?list=UCsvn_Po0SmunchJYtttWpOxMg"
Our preset ``playlist_preset_ex`` defines three
custom variables: ``{output_directory}``, ``{playlist_name}``, and ``{url}``. The subscription sets
the ``parent preset`` to ``playlist_preset_ex``, and must define the variables ``{playlist_name}``
and ``{url}`` since the preset did not.
Beautifying Subscriptions
~~~~~~~~~~~~~~~~~~~~~~~~~
Subscriptions support using presets as keys, and using keys to set override variables as values.
For example:
.. code-block:: yaml
:caption: subscription.yaml
TV Show Full Archive:
= News:
"Breaking News": "https://www.youtube.com/@SomeBreakingNews"
TV Show Only Recent:
= Tech | TV-Y:
"Two Minute Papers": "https://www.youtube.com/@TwoMinutePapers"
Will create two subscriptions named "Breaking News" and "Two Minute Papers", equivalent to:
.. code-block:: yaml
"Breaking News":
preset:
- "TV Show Full Archive"
overrides:
subscription_indent_1: "News"
subscription_name: "Breaking News"
subscription_value: "https://www.youtube.com/@SomeBreakingNews"
"Two Minute Papers":
preset:
- "TV Show Only Recent"
overrides:
subscription_indent_1: "Tech"
subscription_indent_2: "TV-Y"
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 like so in your
parent preset:
.. code-block:: yaml
presets:
"TV Show Preset":
overrides:
subscription_indent_1: "default-genre"
subscription_indent_2: "default-content-rating"
tv_show_name: "{subscription_name}"
url: "{subscription_value}"
genre: "{subscription_indent_1}"
content_rating: "{subscription_indent_2}"
.. _subscription value:
File Preset
~~~~~~~~~~~
You can apply a preset to all subscriptions in the ``subscription.yaml`` file
by using the file-wide ``__preset__``:
.. code-block:: yaml
:caption: subscription.yaml
__preset__:
preset: "playlist_preset_ex"
my_subscription_name:
overrides:
url: "https://youtube.com/playlist?list=UCsvn_Po0SmunchJYtttWpOxMg"
playlist_name: "diy-playlist"
This ``subscription.yaml`` is equivalent to the one above it because all
subscriptions automatically set ``__preset__`` as a ``parent preset``.
Subscription Value
~~~~~~~~~~~~~~~~~~~
NOTE: This is deprecated in favor of using the method in :ref:`config_reference/subscriptions_yaml:beautifying subscriptions`.
With a clever config and use of ``__preset__``, your subscriptions can typically boil
down to a name and url. You can set ``__value__`` to the name of an override variable,
and use the override variable ``subscription_name`` to achieve one-liner subscriptions.
Using the example above, we can do:
.. code-block:: yaml
:caption: subscription.yaml
__preset__:
preset:
- "tv_show"
overrides:
tv_show_name: "{subscription_name}"
__value__: "url"
# single-line subscription, sets "Brandon Acker" and the subscription value
# to the override variables tv_show_name and url
"Brandon Acker": "https://www.youtube.com/@brandonacker"
Traditional subscriptions that can override presets will still work when using ``__value__``.
``__value__`` can also be set within a :ref:`config_reference/config_yaml:config.yaml`.
