Biber::Config(3)

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. If returns the first file found among:

•   "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 some key order information

  get_keyorder
  Get some key order information

  get_keyorder_max
  Get maximum key order number for a section

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

seenkey

  get_seenkey
    Get the count of a key

  incr_seenkey
    Increment the seen count of a key

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)
