'''
Contains various tweaks that affect calibre behavior. Only edit this file if
you know what you are doing. If you delete this file, it will be recreated from
defaults.
'''

#: Auto increment series index
# The algorithm used to assign a new book in an existing series a series number.
# New series numbers assigned using this tweak are always integer values, except
# if a constant non-integer is specified.
# Possible values are:
# next - First available integer larger than the largest existing number
# first_free - First available integer larger than 0
# next_free - First available integer larger than the smallest existing number
# last_free - First available integer smaller than the largest existing number
#             Return largest existing + 1 if no free number is found
# const - Assign the number 1 always
# a number - Assign that number always. The number is not in quotes. Note that
#            0.0 can be used here.
# Examples:
# series_index_auto_increment = 'next'
# series_index_auto_increment = 'next_free'
# series_index_auto_increment = 16.5
series_index_auto_increment = 'next'

#: Add separator after completing an author name
# Should the completion separator be append
# to the end of the completed text to
# automatically begin a new completion operation
# for authors.
# Can be either True or False
authors_completer_append_separator = False


#: Author sort name algorithm
# The algorithm used to copy author to author_sort
# Possible values are:
#  invert: use "fn ln" -> "ln, fn"
#  copy  : copy author to author_sort without modification
#  comma : use 'copy' if there is a ',' in the name, otherwise use 'invert'
#  nocomma : "fn ln" -> "ln fn" (without the comma)
# When this tweak is changed, the author_sort values stored with each author
# must be recomputed by right-clicking on an author in the left-hand tags pane,
# selecting 'manage authors', and pressing 'Recalculate all author sort values'.
# The author name suffixes are words that are ignored when they occur at the
# end of an author name. The case of the suffix is ignored and trailing
# periods are automatically handled.
author_sort_copy_method = 'comma'
author_name_suffixes = ('Jr', 'Sr', 'Inc', 'Ph.D', 'Phd',
                        'MD', 'M.D', 'I', 'II', 'III', 'IV',
                        'Junior', 'Senior')

#: Use author sort in Tag Browser
# Set which author field to display in the tags pane (the list of authors,
# series, publishers etc on the left hand side). The choices are author and
# author_sort. This tweak affects only what is displayed under the authors
# category in the tags pane and content server. Please note that if you set this
# to author_sort, it is very possible to see duplicate names in the list because
# although it is guaranteed that author names are unique, there is no such
# guarantee for author_sort values. Showing duplicates won't break anything, but
# it could lead to some confusion. When using 'author_sort', the tooltip will
# show the author's name.
# Examples:
#   categories_use_field_for_author_name = 'author'
#   categories_use_field_for_author_name = 'author_sort'
categories_use_field_for_author_name = 'author'

#: Control partitioning of Tag Browser
# When partitioning the tags browser, the format of the subcategory label is
# controlled by a template: categories_collapsed_name_template if sorting by
# name, categories_collapsed_rating_template if sorting by average rating, and
# categories_collapsed_popularity_template if sorting by popularity. There are
# two variables available to the template: first and last. The variable 'first'
# is the initial item in the subcategory, and the variable 'last' is the final
# item in the subcategory. Both variables are 'objects'; they each have multiple
# values that are obtained by using a suffix. For example, first.name for an
# author category will be the name of the author. The sub-values available are:
#  name: the printable name of the item
#  count: the number of books that references this item
#  avg_rating: the average rating of all the books referencing this item
#  sort: the sort value. For authors, this is the author_sort for that author
#  category: the category (e.g., authors, series) that the item is in.
# Note that the "r'" in front of the { is necessary if there are backslashes
# (\ characters) in the template. It doesn't hurt anything to leave it there
# even if there aren't any backslashes.
categories_collapsed_name_template = r'{first.sort:shorten(4,,0)} - {last.sort:shorten(4,,0)}'
categories_collapsed_rating_template = r'{first.avg_rating:4.2f:ifempty(0)} - {last.avg_rating:4.2f:ifempty(0)}'
categories_collapsed_popularity_template = r'{first.count:d} - {last.count:d}'


#: Specify columns to sort the booklist by on startup
# Provide a set of columns to be sorted on when calibre starts
#  The argument is None if saved sort history is to be used
#  otherwise it is a list of column,order pairs. Column is the
#  lookup/search name, found using the tooltip for the column
#  Order is 0 for ascending, 1 for descending
# For example, set it to [('authors',0),('title',0)] to sort by
# title within authors.
sort_columns_at_startup = None

#: Control how dates are displayed
# Format to be used for publication date and the timestamp (date).
#  A string controlling how the publication date is displayed in the GUI
#  d    the day as number without a leading zero (1 to 31)
#  dd    the day as number with a leading zero (01 to 31)
#  ddd    the abbreviated localized day name (e.g. 'Mon' to 'Sun').
#  dddd    the long localized day name (e.g. 'Monday' to 'Qt::Sunday').
#  M    the month as number without a leading zero (1-12)
#  MM    the month as number with a leading zero (01-12)
#  MMM    the abbreviated localized month name (e.g. 'Jan' to 'Dec').
#  MMMM    the long localized month name (e.g. 'January' to 'December').
#  yy    the year as two digit number (00-99)
#  yyyy    the year as four digit number
#  For example, given the date of 9 Jan 2010, the following formats show
#  MMM yyyy ==> Jan 2010    yyyy ==> 2010       dd MMM yyyy ==> 09 Jan 2010
#  MM/yyyy ==> 01/2010      d/M/yy ==> 9/1/10   yy ==> 10
# publication default if not set: MMM yyyy
# timestamp default if not set: dd MMM yyyy
gui_pubdate_display_format = 'MMM yyyy'
gui_timestamp_display_format = 'dd MMM yyyy'
gui_last_modified_display_format = 'dd MMM yyyy'

#: Control sorting of titles and series in the library display
# Control title and series sorting in the library view. If set to
# 'library_order', the title sort field will be used instead of the title.
# Unless you have manually edited the title sort field, leading articles such as
# The and A will be ignored. If set to 'strictly_alphabetic', the titles will be
# sorted as-is (sort by title instead of title sort). For example, with
# library_order, The Client will sort under 'C'. With strictly_alphabetic, the
# book will sort under 'T'.
# This flag affects Calibre's library display. It has no effect on devices. In
# addition, titles for books added before changing the flag will retain their
# order until the title is edited. Double-clicking on a title and hitting return
# without changing anything is sufficient to change the sort.
title_series_sorting = 'library_order'

#: Control formatting of title and series when used in templates
# Control how title and series names are formatted when saving to disk/sending
# to device. The behavior depends on the field being processed. If processing
# title, then if this tweak is set to 'library_order', the title will be
# replaced with title_sort. If it is set to 'strictly_alphabetic', then the
# title will not be changed. If processing series, then if set to
# 'library_order', articles such as 'The' and 'An' will be moved to the end. If
# set to 'strictly_alphabetic', the series will be sent without change.
# For example, if the tweak is set to library_order, "The Lord of the Rings"
# will become "Lord of the Rings, The". If the tweak is set to
# strictly_alphabetic, it would remain "The Lord of the Rings".
save_template_title_series_sorting = 'library_order'

#: Set the list of words considered to be "articles" for sort strings
# Set the list of words that are to be considered 'articles' when computing the
# title sort strings. The list is a regular expression, with the articles
# separated by 'or' bars. Comparisons are case insensitive, and that cannot be
# changed. Changes to this tweak won't have an effect until the book is modified
# in some way. If you enter an invalid pattern, it is silently ignored.
# To disable use the expression: '^$'
# Default: '^(A|The|An)\s+'
title_sort_articles=r'^(A|The|An)\s+'

#: Specify a folder calibre should connect to at startup
# Specify a folder that calibre should connect to at startup using
# connect_to_folder. This must be a full path to the folder. If the folder does
# not exist when calibre starts, it is ignored. If there are '\' characters in
# the path (such as in Windows paths), you must double them.
# Examples:
#     auto_connect_to_folder = 'C:\\Users\\someone\\Desktop\\testlib'
#     auto_connect_to_folder = '/home/dropbox/My Dropbox/someone/library'
auto_connect_to_folder = ''

#: Specify renaming rules for SONY collections
# Specify renaming rules for sony collections. This tweak is only applicable if
# metadata management is set to automatic. Collections on Sonys are named
# depending upon whether the field is standard or custom. A collection derived
# from a standard field is named for the value in that field. For example, if
# the standard 'series' column contains the value 'Darkover', then the
# collection name is 'Darkover'. A collection derived from a custom field will
# have the name of the field added to the value. For example, if a custom series
# column named 'My Series' contains the name 'Darkover', then the collection
# will by default be named 'Darkover (My Series)'. For purposes of this
# documentation, 'Darkover' is called the value and 'My Series' is called the
# category. If two books have fields that generate the same collection name,
# then both books will be in that collection.
# This set of tweaks lets you specify for a standard or custom field how
# the collections are to be named. You can use it to add a description to a
# standard field, for example 'Foo (Tag)' instead of the 'Foo'. You can also use
# it to force multiple fields to end up in the same collection. For example, you
# could force the values in 'series', '#my_series_1', and '#my_series_2' to
# appear in collections named 'some_value (Series)', thereby merging all of the
# fields into one set of collections.
# There are two related tweaks. The first determines the category name to use
# for a metadata field.  The second is a template, used to determines how the
# value and category are combined to create the collection name.
# The syntax of the first tweak, sony_collection_renaming_rules, is:
# {'field_lookup_name':'category_name_to_use', 'lookup_name':'name', ...}
# The second tweak, sony_collection_name_template, is a template. It uses the
# same template language as plugboards and save templates. This tweak controls
# how the value and category are combined together to make the collection name.
# The only two fields available are {category} and {value}. The {value} field is
# never empty. The {category} field can be empty. The default is to put the
# value first, then the category enclosed in parentheses, it is isn't empty:
# '{value} {category:|(|)}'
# Examples: The first three examples assume that the second tweak
# has not been changed.
# 1: I want three series columns to be merged into one set of collections. The
# column lookup names are 'series', '#series_1' and '#series_2'. I want nothing
# in the parenthesis. The value to use in the tweak value would be:
#    sony_collection_renaming_rules={'series':'', '#series_1':'', '#series_2':''}
# 2: I want the word '(Series)' to appear on collections made from series, and
# the word '(Tag)' to appear on collections made from tags. Use:
#    sony_collection_renaming_rules={'series':'Series', 'tags':'Tag'}
# 3: I want 'series' and '#myseries' to be merged, and for the collection name
# to have '(Series)' appended. The renaming rule is:
#    sony_collection_renaming_rules={'series':'Series', '#myseries':'Series'}
# 4: Same as example 2, but instead of having the category name in parentheses
# and appended to the value, I want it prepended and separated by a colon, such
# as in Series: Darkover. I must change the template used to format the category name
# The resulting two tweaks are:
#    sony_collection_renaming_rules={'series':'Series', 'tags':'Tag'}
#    sony_collection_name_template='{category:||: }{value}'
sony_collection_renaming_rules={}
sony_collection_name_template='{value}{category:| (|)}'

#: Specify how SONY collections are sorted
# Specify how sony collections are sorted. This tweak is only applicable if
# metadata management is set to automatic. You can indicate which metadata is to
# be used to sort on a collection-by-collection basis. The format of the tweak
# is a list of metadata fields from which collections are made, followed by the
# name of the metadata field containing the sort value.
# Example: The following indicates that collections built from pubdate and tags
# are to be sorted by the value in the custom column '#mydate', that collections
# built from 'series' are to be sorted by 'series_index', and that all other
# collections are to be sorted by title. If a collection metadata field is not
# named, then if it is a series- based collection it is sorted by series order,
# otherwise it is sorted by title order.
# [(['pubdate', 'tags'],'#mydate'), (['series'],'series_index'), (['*'], 'title')]
# Note that the bracketing and parentheses are required. The syntax is
# [ ( [list of fields], sort field ) , ( [ list of fields ] , sort field ) ]
# Default: empty (no rules), so no collection attributes are named.
sony_collection_sorting_rules = []


#: Control how tags are applied when copying books to another library
# Set this to True to ensure that tags in 'Tags to add when adding
# a book' are added when copying books to another library
add_new_book_tags_when_importing_books = False


#: Set the maximum number of tags to show per book in the content server
max_content_server_tags_shown=5


#: Set custom metadata fields that the content server will or will not display.
# content_server_will_display is a list of custom fields to be displayed.
# content_server_wont_display is a list of custom fields not to be displayed.
# wont_display has priority over will_display.
# The special value '*' means all custom fields. The value [] means no entries.
# Defaults:
#    content_server_will_display = ['*']
#    content_server_wont_display = []
# Examples:
# To display only the custom fields #mytags and #genre:
#   content_server_will_display = ['#mytags', '#genre']
#   content_server_wont_display = []
# To display all fields except #mycomments:
#   content_server_will_display = ['*']
#   content_server_wont_display['#mycomments']
content_server_will_display = ['*']
content_server_wont_display = []

#: Set the maximum number of sort 'levels'
# Set the maximum number of sort 'levels' that calibre will use to resort the
# library after certain operations such as searches or device insertion. Each
# sort level adds a performance penalty. If the database is large (thousands of
# books) the penalty might be noticeable. If you are not concerned about multi-
# level sorts, and if you are seeing a slowdown, reduce the value of this tweak.
maximum_resort_levels = 5

#: Specify which font to use when generating a default cover
# Absolute path to .ttf font files to use as the fonts for the title, author
# and footer when generating a default cover. Useful if the default font (Liberation
# Serif) does not contain glyphs for the language of the books in your library.
generate_cover_title_font = None
generate_cover_foot_font = None

#: Control behavior of double clicks on the book list
# Behavior of doubleclick on the books list. Choices: open_viewer, do_nothing,
# edit_cell, edit_metadata. Selecting edit_metadata has the side effect of
# disabling editing a field using a single click.
# Default: open_viewer.
# Example: doubleclick_on_library_view = 'do_nothing'
doubleclick_on_library_view = 'open_viewer'


#: Language to use when sorting.
# Setting this tweak will force sorting to use the
# collating order for the specified language. This might be useful if you run
# calibre in English but want sorting to work in the language where you live.
# Set the tweak to the desired ISO 639-1 language code, in lower case.
# You can find the list of supported locales at
# http://publib.boulder.ibm.com/infocenter/iseries/v5r3/topic/nls/rbagsicusortsequencetables.htm
# Default: locale_for_sorting = '' -- use the language calibre displays in
# Example: locale_for_sorting = 'fr' -- sort using French rules.
# Example: locale_for_sorting = 'nb' -- sort using Norwegian rules.
locale_for_sorting =  ''

#: Number of columns for custom metadata in the edit metadata dialog
# Set whether to use one or two columns for custom metadata when editing
# metadata  one book at a time. If True, then the fields are laid out using two
# columns. If False, one column is used.
metadata_single_use_2_cols_for_custom_fields = True

#: The number of seconds to wait before sending emails
# The number of seconds to wait before sending emails when using a
# public email server like gmail or hotmail. Default is: 5 minutes
# Setting it to lower may cause the server's SPAM controls to kick in,
# making email sending fail. Changes will take effect only after a restart of
# calibre.
public_smtp_relay_delay = 301

#: Remove the bright yellow lines at the edges of the book list
# Control whether the bright yellow lines at the edges of book list are drawn
# when a section of the user interface is hidden. Changes will take effect
# after a restart of calibre.
draw_hidden_section_indicators = True

#: The maximum width and height for covers saved in the calibre library
# All covers in the calibre library will be resized, preserving aspect ratio,
# to fit within this size. This is to prevent slowdowns caused by extremely
# large covers
maximum_cover_size = (1200, 1600)

#: Where to send downloaded news
# When automatically sending downloaded news to a connected device, calibre
# will by default send it to the main memory. By changing this tweak, you can
# control where it is sent. Valid values are "main", "carda", "cardb". Note
# that if there isn't enough free space available on the location you choose,
# the files will be sent to the location with the most free space.
send_news_to_device_location = "main"

#: What interfaces should the content server listen on
# By default, the calibre content server listens on '0.0.0.0' which means that it
# accepts IPv4 connections on all interfaces. You can change this to, for
# example, '127.0.0.1' to only listen for connections from the local machine, or
# to '::' to listen to all incoming IPv6 and IPv4 connections (this may not
# work on all operating systems)
server_listen_on = '0.0.0.0'

#: Unified toolbar on OS X
# If you enable this option and restart calibre, the toolbar will be 'unified'
# with the titlebar as is normal for OS X applications. However, doing this has
# various bugs, for instance the minimum width of the toolbar becomes twice
# what it should be and it causes other random bugs on some systems, so turn it
# on at your own risk!
unified_title_toolbar_on_osx = False
