Description Enable mature content.

            This option simply sets the |mature_content|_ parameter for API
            calls to either ``"true"`` or ``"false"`` and does not do any other

Default     ``3.0``
Description Minimum wait time in seconds between each image

            Exhentai detects and blocks automated downloaders.

=========== =====
Type        ``integer`` or ``string``
Default     ``null``
Description Sets the maximum allowed size for downloaded images.

            * If this is an ``integer``, it specifies the maximum image dimension
              (width and height) in pixels.
            * If this is a ``string``, it should be one of Flickr's format specifiers
              (``"Original"``, ``"Large"``, ... or ``o``, ``k``, ``h``, ``l``, ...)
              to use these as an upper limit.
=========== =====


extractor.gfycat.format
-----------------------
=========== =====
Type        ``string``

Description The name of the preferred animation format, which can be one of
            ``"mp4"``, ``"webm"``, ``"gif"``, ``"webp"`` or ``"mjpg"``.

            If the selected format is not available, ``"mp4"``, ``"webm"``
            and ``"gif"`` (in that order) will be tried instead, until an
            available format is found.
=========== =====


extractor.imgur.mp4
-------------------
=========== =====
Type        ``bool`` or ``string``
Default     ``true``

            * ``true``: Follow Imgur's advice and choose MP4 if the
              ``prefer_video`` flag in an image's metadata is set.
            * ``false``: Always choose GIF.
            * ``"always"``: Always choose MP4.
=========== =====


extractor.oauth.browser
-----------------------
=========== =====
Type        ``bool``
Default     ``true``
Description Controls how a user is directed to a OAuth authorization site.

            * ``true``: Use Python's |webbrowser.open()|_ method to automatically
              open the URL in the user's browser.
            * ``false``: Ask the user to copy & paste an URL from the terminal.
=========== =====


extractor.pixiv.ugoira

Type        ``bool``
Default     ``true``
Description Download Pixiv's Ugoira animations or ignore them.

            These animations come as a ``.zip`` file containing all the single
            animation frames in JPEG format.

Type        ``integer`` or ``string``
Default     ``200``
Description The value of the ``limit`` parameter when loading
            a submission and its comments.
            This number (roughly) specifies the total amount of comments
            being retrieved with the first API call.

            Reddit's internal default and maximum values for this parameter
            appear to be 200 and 500 respectively.

            The value `0` ignores all comments and significantly reduces to time
            required when scanning a subreddit.
=========== =====


extractor.reddit.morecomments
-----------------------------
=========== =====
Type        ``bool``
Default     ``false``
Description Retrieve additional comments by resolving the ``more`` comment
            stubs in the base commment tree.

            This requires 1 additional API call for every 100 extra comments.
=========== =====


extractor.reddit.date-min
-------------------------
=========== =====
Type        ``integer`` (UTC timestamp)
Default     ``0``
Description Ignore all submissions posted before this timestamp.
=========== =====


extractor.reddit.date-max
-------------------------
=========== =====
Type        ``integer`` (UTC timestamp)
Default     ``253402210800`` (timestamp of ``datetime.max``)
Description Ignore all submissions posted after this timestamp.
=========== =====


extractor.reddit.recursion
--------------------------
=========== =====
Type        ``integer``
Default     ``0``
Description Reddit extractors can recursively visit other submissions
            linked to in the initial set of submissions.
            This value sets the maximum recursion depth.

            Special values:

            * ``0``: Recursion is disabled
            * ``-1``: Infinite recursion (don't do this)
=========== =====


extractor.reddit.refresh-token
------------------------------
=========== =====
Type        ``string``
Default     ``null``
Description The ``refresh_token`` value you get from linking your Reddit account
            to ``gallery-dl``.

            Using the ``refresh_token`` allows you to access private or otherwise
            not publicly available subreddits, given that your account is
            authorized to do so,
            but requests to the reddit API are going to be rate limited
            at 600 requests every 10 minutes/600 seconds.
