module MediaWiktory::Wikipedia
  module Modules
    # Returns file information for stashed files.
    #
    # The "submodule" (MediaWiki API term) is included in action after setting some param, providing
    # additional tweaking for this param. Example (for {MediaWiktory::Wikipedia::Actions::Query} and
    # its submodules):
    #
    # ```ruby
    # api.query             # returns Actions::Query
    #    .prop(:revisions)  # adds prop=revisions to action URL, and includes Modules::Revisions into action
    #    .limit(10)         # method of Modules::Revisions, adds rvlimit=10 to URL
    # ```
    #
    # All submodule's parameters are documented as its public methods, see below.
    #
    module Stashimageinfo

      # @param values [Array<String>] Allowed values: "timestamp" (Adds timestamp for the uploaded version), "canonicaltitle" (Adds the canonical title of the file), "url" (Gives URL to the file and the description page), "size" (Adds the size of the file in bytes and the height, width and page count (if applicable)), "dimensions" (Alias for size), "sha1" (Adds SHA-1 hash for the file), "mime" (Adds MIME type of the file), "thumbmime" (Adds MIME type of the image thumbnail (requires url and param siiurlwidth)), "metadata" (Lists Exif metadata for the version of the file), "commonmetadata" (Lists file format generic metadata for the version of the file), "extmetadata" (Lists formatted metadata combined from multiple sources. Results are HTML formatted), "bitdepth" (Adds the bit depth of the version), "badfile" (Adds whether the file is on the MediaWiki:Bad image list).
