==================

downloader.part
---------------
=========== =====
Type        ``bool``
Default     ``true``
Description Controls the use of ``.part`` files during file downloads.

            * ``true``: Write downloaded data into ``.part`` files and rename
              them upon download completion. This mode additionally supports
              resuming incomplete downloads.
            * ``false``: Do not use ``.part`` files and write data directly
              into the actual output files.
=========== =====


downloader.part-directory
-------------------------
=========== =====
Type        ``string``
Default     ``null``
Description Alternate location for ``.part`` files.

            Missing directories will be created as needed.
            If this value is ``null``, ``.part`` files are going to be stored
            alongside the actual output files.
=========== =====


downloader.http.rate
--------------------
=========== =====
Type        ``string``
Default     ``null``
Examples    ``"32000"``, ``"500k"``, ``"2.5M"``
Description Maximum download rate in bytes per second.

            Possible values are valid integer or floating-point numbers
            optionally followed by one of ``k``, ``m``. ``g``, ``t`` or ``p``.
            These suffixes are case-insensitive.
=========== =====

Default     ``30``
Description Amount of time (in seconds) to wait for a successful connection
            and response from a remote server.

            This value gets internally used as the |timeout|_ parameter for the
            |requests.request()|_ method during downloads.
=========== =====


downloader.http.verify
----------------------
=========== =====
Type        ``bool`` or ``string``
Default     ``true``
Description Controls whether to verify SSL/TLS certificates for HTTPS requests.

            If this is a ``string``, it must be the path to a CA bundle to use
            instead of the default certificates.

            This value gets internally used as the |verify|_ parameter for the
            |requests.request()|_ method during downloads.
=========== =====


Extractor Options
=================

Each extractor is identified by its ``category`` and ``subcategory``.
The ``category`` is the lowercase site name without any spaces or special
characters, which is usually just the module name
(``pixiv``, ``batoto``, ...).
The ``subcategory`` is a lowercase word describing the general functionality
of that extractor (``user``, ``favorite``, ``manga``, ...).

Each one of the following options can be specified on multiple levels of the
configuration tree:

================== =====
Base level:        ``extractor.<option-name>``
Category level:    ``extractor.<category>.<option-name>``
Subcategory level: ``extractor.<category>.<subcategory>.<option-name>``
================== =====

A value in a "deeper" level hereby overrides a value of the same name on a
lower level. Setting the ``extractor.pixiv.filename`` value, for example, lets
you specify a general filename pattern for all the different pixiv extractors.
Using the ``extractor.pixiv.user.filename`` value lets you override this
general pattern specifically for ``PixivUserExtractor`` instances.

The ``category`` and ``subcategory`` of all extractors are included in the
output of ``gallery-dl --list-extractors``. For a specific URL these values
can also be determined by using the ``-K``/``--list-keywords`` command-line
option (see the example below).

extractor.*.filename
--------------------
=========== =====
Type        ``string``
Example     ``"{manga}_c{chapter}_{page:>03}.{extension}"``
Description A `format string`_ to build the resulting filename
            for a downloaded file.

            The available replacement keys depend on the extractor used. A list
            of keys for a specific one can be acquired by calling *gallery-dl*
            with the ``-K``/``--list-keywords`` command-line option.
            For example:

            .. code::

                $ gallery-dl -K http://seiga.nicovideo.jp/seiga/im5977527
                Keywords for directory names:
                -----------------------------
                category
                  seiga
                subcategory
                  image

                Keywords for filenames:
                -----------------------
                category
                  seiga
                extension
                  None
                image-id
                  5977527
                subcategory
                  image

            Note that even if the value of the ``extension`` key is missing or
            ``None``, it will filled in later when the file download is
            starting. This key is therefore always available to provide
            a valid filename extension.
=========== =====


extractor.*.directory
---------------------
=========== =====
Type        ``list`` of ``strings``
Example     ``["{category}", "{manga}", "c{chapter} - {title}"]``
Description A list of `format strings`_ for the resulting target directory.

            Each individual string in such a list represents a single path
            segment, which will be joined together and prepended with the
            base-directory_ to form the complete target directory path.
=========== =====


extractor.*.skip
----------------
=========== =====
Type        ``bool`` or ``string``
Default     ``true``
Description Controls the behavior when downloading a file whose filename
            already exists.

            * ``true``: Skip the download
            * ``false``: Overwrite the already existing file
            * ``"abort"``: Abort the current extractor run
            * ``"exit"``: Exit the program altogether
=========== =====


extractor.*.sleep
-----------------
=========== =====
Type        ``float``
Default     ``0``
Description Number of seconds to sleep before each download.
=========== =====


extractor.*.username & .password
--------------------------------
=========== =====
Type        ``string``
Default     ``null``
Description The username and password to use when attempting to log in to
            another site.

            Specifying username and password is
            required for the ``pixiv``, ``nijie`` and ``seiga`` modules and
            optional (but strongly recommended) for ``batoto``, ``exhentai``
            and ``sankaku``.

            These values can also be set via the ``-u/--username`` and
            ``-p/--password`` command-line options or by using a |.netrc|_ file.
            (see Authentication_)
=========== =====


extractor.*.cookies
-------------------
=========== =====
Type        ``string`` or ``object``
Default     ``null``
Description Source to read additional cookies from.

            * If this is a ``string``, it specifies the path of a
              Mozilla/Netscape format cookies.txt file.
            * If this is an ``object``, its key-value pairs, which should both
              be ``strings``, will be used as cookie-names and -values.
=========== =====


extractor.*.proxy
-----------------
=========== =====
Type        ``string`` or ``object``
Default     ``null``
Description Proxy (or proxies) to be used for remote connections.

            * If this is a ``string``, it is the proxy URL for all
              outgoing requests.
            * If this is an ``object``, it is a scheme-to-proxy mapping to
              specify different proxy URLs for each scheme.
              It is also possible to set a proxy for a specific host by using
              ``scheme://host`` as key.
              See `Requests' proxy documentation`_ for more details.

              Example:

              .. code::

                {
                    "http": "http://10.10.1.10:3128",
                    "https": "http://10.10.1.10:1080",
                    "http://10.20.1.128": "http://10.10.1.10:5323"
                }

            Note that all proxy URLs should include a scheme,
            otherwise ``http://`` is assumed.
=========== =====


extractor.*.user-agent
----------------------
=========== =====
Type        ``string``
Default     ``"Mozilla/5.0 (X11; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0"``
Description User-Agent header value to be used for HTTP requests.

            Note that this option has no effect on `pixiv` and
            `readcomiconline` extractors, as these need specific values to
            function correctly.
=========== =====


extractor.*.keywords
--------------------
=========== =====
Type        ``object``
Example     ``{"type": "Pixel Art", "type_id": 123}``
Description Additional key-value pairs to be added to each metadata dictionary.
=========== =====


extractor.*.archive
-------------------
=========== =====
Type        ``string``
Default     ``null``
Description File to store IDs of downloaded files in. Downloads of files
            already recorded in this archive file will be skipped_.

            The resulting archive file is not a plain text file but an SQLite3
            database, as lookup operations are significantly faster when the
            amount of stored IDs gets reasonably large.
=========== =====


Extractor-specific Options
==========================

extractor.deviantart.flat
-------------------------
=========== =====
Type        ``bool``
Default     ``true``
Description Select the directory structure created by the Gallery- and
            Favorite-Extractors.

            * ``true``: Use a flat directory structure.
            * ``false``: Collect a list of all gallery-folders or
              favorites-collections and transfer any further work to other
              extractors (``folder`` or ``collection``), which will then
              create individual subdirectories for each of them.
=========== =====


extractor.deviantart.mature
---------------------------
=========== =====
Type        ``bool``
Default     ``true``
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
            form of content filtering.
=========== =====


extractor.deviantart.original
-----------------------------
=========== =====
Type        ``bool``
Default     ``true``
Description Request full-sized original images if available.

            Some of DeviantArt's images require an additional API call to get
            their actual original version, which is being hosted on
            Amazon Web Services (AWS) servers.

Type        ``float``
Default     ``3.0`` and ``6.0``
Description Minimum and maximum wait time in seconds between each image

            ExHentai detects and blocks automated downloaders.
            *gallery-dl* waits a randomly selected number of
            seconds between ``wait-min`` and ``wait-max`` after
            each image to prevent getting blocked.
=========== =====


extractor.flickr.access-token & .access-token-secret
----------------------------------------------------
=========== =====
Type        ``string``
Default     ``null``
Description The ``access_token`` and ``access_token_secret`` values you get

            * 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 as an upper limit.
=========== =====


extractor.gelbooru.api
----------------------
=========== =====
Type        ``bool``
Default     ``true``
Description Enable use of Gelbooru's API.

            Set this value to `false` if the API has been disabled to switch
            to manual information extraction.
=========== =====


extractor.gfycat.format
-----------------------
=========== =====
Type        ``string``
Default     ``"mp4"``
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

Default     ``true``
Description Controls whether to choose the GIF or MP4 version of an animation.

            * ``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 an 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``

=========== =====


extractor.recursive.blacklist
-----------------------------
=========== =====
Type        ``list`` of ``strings``
Default     ``["directlink", "oauth", "recursive", "test"]``
Description A list of extractor categories which should be ignored when using
            the ``recursive`` extractor.
=========== =====


extractor.reddit.comments
-------------------------
=========== =====
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 comment tree.

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


extractor.reddit.date-min & .date-max
-------------------------------------
=========== =====
Type        ``integer`` or ``string``
Default     ``0`` and ``253402210800`` (timestamp of |datetime.max|_)
Description Ignore all submissions posted before/after this date.

            * If this is an ``integer``, it represents the date as UTC timestamp.
            * If this is a ``string``, it will get parsed according to date-format_.
=========== =====


extractor.reddit.date-format
----------------------------
=========== =====
Type        ``string``
Default     ``"%Y-%m-%dT%H:%M:%S"``
Description An explicit format string used to parse the ``string`` values of
            `date-min and date-max`_.

            See |strptime|_ for a list of formatting directives.
=========== =====


extractor.reddit.id-min & .id-max
---------------------------------
=========== =====
Type        ``string``
Example     ``"6kmzv2"``
Description Ignore all submissions posted before/after the submission with
            this ID.
=========== =====


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 a ``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.
=========== =====


extractor.sankaku.wait-min & .wait-max
--------------------------------------
=========== =====
Type        ``float``
Default     ``2.0`` and ``4.0``
Description Minimum and maximum wait time in seconds between each image

            Sankaku Channel responds with ``429 Too Many Requests`` if it
            receives too many HTTP requests in a certain amount of time.
            Waiting a few seconds between each request tries to prevent that.
=========== =====


extractor.tumblr.external
-------------------------
=========== =====
Type        ``bool``
Default     ``false``
Description Follow external URLs (e.g. from "Link" posts) and try to extract
            images from them.
=========== =====


extractor.tumblr.inline
-----------------------
=========== =====
Type        ``bool``

Description A comma-separated list of post types to extract images, etc. from.
            For example: ``"text,link,photo"``.

            Possible types are ``text``, ``quote``, ``link``, ``answer``,
            ``video``, ``audio``, ``photo``, ``chat``.

            You can use ``"all"`` instead of listing all types separately.
=========== =====



API Tokens & IDs
================
