NAME

Biber::Config - Configuration items which need to be saved across the
lifetime of a Biber object 
  This class contains a static object and static methods to access
  configuration and state data. There are several classes of data in here
  which have separate accessors:
  * Biber options
  * Biblatex options
  * State information used by Biber as it processes entries
  * displaymode date

_init

    Reset internal hashes to defaults.

_initopts

    Initialise default options, optionally with config file as argument

config_file

Returns the full path of the Biber configuration file. It returns the first file found among:
•
"biber.conf" or ".biber.conf" in the current directory
•
"$HOME/.biber.conf"
•
"$ENV{XDG_CONFIG_HOME}/biber/biber.conf"
•
"$HOME/.config/biber/biber.conf"
•
"$HOME/Library/biber/biber.conf" (Mac OSX only)
•
"$ENV{APPDATA}/biber.conf" (Windows only)
•
the output of "kpsewhich biber.conf" (if available on the system).
If no file is found, it returns "undef".

add_uniq_ignore

    Track uniqueness ignore settings found in inheritance data

get_uniq_ignore

    Retrieve uniqueness ignore settings found in inheritance data

postprocess_biber_opts

    Place to postprocess biber options when they have been
    gathered from all the possible places that set them

set_dm

    Sets the data model information object

get_dm

    Gets the data model information object

get_dm_helpers

    Sets the datamodel helper lists

set_ctrlfile_path

    Stores the path to the control file

get_ctrlfile_path

    Retrieved the path to the control file

setoption

    Store a Biber config option

getoption

    Get a Biber option

setcmdlineoption

    Store a Biber command-line option

setconfigfileoption

    Store a Biber config-file option

iscmdlineoption

    Check if an option is explicitly set by user on the command
    line

isconfigfileoption

    Check if an option is explicitly set by user in their
    config file

isexplicitoption

    Check if an option is explicitly set by user on the command
    line or in the config file

addtoblxoption

    Add to an array global biblatex option

setblxoption

    Set a biblatex option on the appropriate scope

getblxoption

    Get a biblatex option from the global, per-type or per entry scope
    getblxoption('secnum', 'option', ['entrytype'], ['citekey'])
    Returns the value of option. In order of decreasing preference, returns:
    1. Biblatex option defined for entry
    2. Biblatex option defined for entry type
    3. Biblatex option defined globally
    section number needs to be present only for per-entry options as these might
    differ between sections

getblxentryoptions

    Get all per-entry options for an entry

set_graph

   Record node and arc connection types for .dot output

get_graph

    Return an inheritance graph data structure for an inheritance type

set_inheritance

    Record that $target inherited information from $source
    Can be used for crossrefs and xdata. This just records that an entry
    inherited from another entry, for loop detection.

get_inheritance

    Check if $target directly inherited information from $source
    Can be used for crossrefs and xdata

is_inheritance_path

  Checks for an inheritance path from entry $e1 to $e2
  Can be used for crossrefs and xdata
[
{s => 'A',
t => 'B'},
{s => 'A',
t => 'E'},
{s => 'B',
t => 'C'},
{s => 'C',
t => 'D'} ];

keyorder

set_keyorder

  Set key order information

set_internal_keyorder

  Set key order information for keys with the same order

get_keyorder

  Get key order information

get_internal_keyorder

  Get key order information for keys with the same order

get_keyorder_max

  Get maximum key order number for a section

reset_keyorder

  Reset keyorder - for use in tests where we switch to allkeys

crossrefkeys

get_crossrefkeys

    Return ref to array of keys which are crossref targets

xrefkeys

get_xrefkeys

    Return ref to array of keys which are xref targets

get_crossrefkey

    Return an integer representing the number of times a
    crossref target key has been ref'ed

get_xrefkey

    Return an integer representing the number of times a
    xref target key has been ref'ed

del_crossrefkey

    Remove a crossref target key from the crossrefkeys state

del_xrefkey

    Remove a xref target key from the xrefkeys state

incr_crossrefkey

    Increment the crossreferences count for a target crossref key

incr_xrefkey

    Increment the xreferences count for a target xref key

dump

    Dump config information (for debugging)
