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``, ``danbooru``, ...).
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 appended to the
            base-directory_ to form the complete target directory path.
=========== =====


extractor.*.base-directory
--------------------------
=========== =====
Type        |Path|_
Default     ``"./gallery-dl/"``
Description Directory path used as the base for all download destinations.
=========== =====


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 ``exhentai``,
            ``sankaku`` and ``idolcomplex``.

            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        |Path|_ or ``object``
Default     ``null``
Description Source to read additional cookies from.

            * If this is a |Path|_, it specifies 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.*.keywords-default
----------------------------
=========== =====
Type        any
Default     ``"None"``
Description Default value used for missing or undefined keyword names in
            format strings.
=========== =====


extractor.*.archive
-------------------
=========== =====
Type        |Path|_
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 either lookup operations are significantly faster or
            memory requirements are significantly lower when the
            amount of stored IDs gets reasonably large.
=========== =====


extractor.*.archive-format
--------------------------
=========== =====
Type        ``string``
Example     ``"{id}_{offset}"``
Description An alternative `format string`_ to build archive IDs with.
=========== =====


extractor.*.postprocessors
--------------------------
=========== =====
Type        ``list`` of |Postprocessor Configuration|_ objects
Example     .. code::

                [
                    {"name": "zip", "compression": "zip"},
                    {"name": "exec",  "command": ["/home/asd/script", "{category}", "{image_id}"]}
                ]

Description A list of post-processors to be applied to each downloaded file
            in the same order as they are specified.

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


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``

            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
----------------------------------------------------
=========== =====

              (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

            * ``false``: Always choose GIF.
            * ``"always"``: Always choose MP4.
=========== =====

Type        ``integer`` or ``string``
Default     ``500``
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 the
            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.

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.
=========== =====

---------------------------------
=========== =====
Type        ``string``
Example     ``"6kmzv2"``

            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     ``3.0`` and ``6.0``
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

Type        ``bool``
Default     ``true``
Description Extract images from retweets.
=========== =====

            instead of the default certificates.

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

Custom Types
============


Path
----
=========== =====
Type        ``string`` or ``list`` of ``strings``
Examples    * ``"file.ext"``
            * ``"~/path/to/file.ext"``
            * ``"$HOME/path/to/file.ext"``
            * ``["$HOME", "path", "to", "file.ext"]``
Description A |Path|_ is a ``string`` representing the location of a file
            or directory.

            Simple `tilde expansion <https://docs.python.org/3/library/os.path.html#os.path.expanduser>`__
            and `environment variable expansion <https://docs.python.org/3/library/os.path.html#os.path.expandvars>`__
            is supported.

            In Windows environments, backslashes (``"\"``) can, in addition to
            forward slashes (``"/"``), be used as path separators.
            Because backslashes are JSON's escape character,
            they themselves have to be escaped.
            The path ``C:\path\to\file.ext`` has therefore to be written as
            ``"C:\\path\\to\\file.ext"`` if you want to use backslashes.
=========== =====


Logging Configuration
---------------------
=========== =====
Type        ``object``

Example     .. code::

                {

                    "path": "~/log.txt",
                    "encoding": "ascii"
                }

Description Extended logging output configuration.

            * format
                * Format string for logging messages

            * format-date
                * Format string for ``{asctime}`` fields in logging messages
                  (see `strftime() directives <https://docs.python.org/3/library/time.html#time.strftime>`__)
                * Default: ``"%Y-%m-%d %H:%M:%S"``
            * level
                * Minimum logging message level
                  (one of ``"debug"``, ``"info"``, ``"warning"``, ``"error"``, ``"exception"``)
                * Default: ``"info"``
            * path
                * |Path|_ to the output file
            * mode
                * Mode in which the file is opened;
                  use ``"w"`` to truncate or ``"a"`` to append
                  (see `open() <https://docs.python.org/3/library/functions.html#open>`__)
                * Default: ``"w"``
            * encoding
                * File encoding
                * Default: ``"utf-8"``

            Note: path, mode and encoding are only applied when configuring
            logging output to a file.
