FUNCTIONS

locate_biber_file

  Searches for a file by
  The exact path if the filename is absolute
  In the input_directory, if defined
  In the output_directory, if defined
  Relative to the current directory
  In the same directory as the control file
  Using kpsewhich, if available

biber_warn

    Wrapper around various warnings bits and pieces
    Logs a warning, add warning to the list of .bbl warnings and optionally
    increments warning count in Biber object, if present

biber_error

    Wrapper around error logging
    Forces an exit.

makenamesid

Given a Biber::Names object, return an underscore normalised concatenation of all of the full name strings.

makenameid

Given a Biber::Name object, return an underscore normalised concatenation of the full name strings.

latex_recode_output

  Tries to convert UTF-8 to TeX macros in passed string

strip_noinit

  Removes elements which are not to be considered during initials generation
  in names

strip_nosort

  Removes elements which are not to be used in sorting a name from a string

normalise_string_label

Remove some things from a string for label generation, like braces. It also decodes LaTeX character macros into Unicode as this is always safe when normalising strings for sorting since they don't appear in the output.

normalise_string_sort

Removes LaTeX macros, and all punctuation, symbols, separators and control characters, as well as leading and trailing whitespace for sorting strings. It also decodes LaTeX character macros into Unicode as this is always safe when normalising strings for sorting since they don't appear in the output.

normalise_string

Removes LaTeX macros, and all punctuation, symbols, separators and control characters, as well as leading and trailing whitespace for sorting strings. Only decodes LaTeX character macros into Unicode if output is UTF-8

normalise_string_common

  Common bit for normalisation

normalise_string_hash

  Normalise strings used for hashes. We collapse LaTeX macros into a vestige
  so that hashes are unique between things like:
  Smith
  {\v S}mith
  we replace macros like this to preserve their vestiges:
  \v S -> v:
  \" -> 34:

normalise_string_underscore

  Like normalise_string, but also substitutes ~ and whitespace with underscore.

escape_label

  Escapes a few special character which might be used in labels

unescape_label

  Unscapes a few special character which might be used in label but which need
  sorting without escapes

reduce_array

reduce_array(\@a, \@b) returns all elements in @a that are not in @b

remove_outer

    Remove surrounding curly brackets:
        '{string}' -> 'string'

add_outer

    Add surrounding curly brackets:
        'string' -> '{string}'

ucinit

    upper case of initial letters in a string

is_undef

    Checks for undefness of arbitrary things, including
    composite method chain calls which don't reliably work
    with defined() (see perldoc for defined())
    This works because we are just testing the value passed
    to this sub. So, for example, this is randomly unreliable
    even if the resulting value of the arg to defined() is "undef":
    defined($thing->method($arg)->method)
    wheras:
    is_undef($thing->method($arg)->method)
    works since we only test the return value of all the methods
    with defined()

is_def

    Checks for definedness in the same way as is_undef()

is_undef_or_null

    Checks for undef or nullness (see is_undef() above)

is_def_and_notnull

    Checks for def and unnullness (see is_undef() above)

is_def_and_null

    Checks for def and nullness (see is_undef() above)

is_null

    Checks for nullness

is_notnull

    Checks for notnullness

is_notnull_scalar

    Checks for notnullness of a scalar

is_notnull_array

    Checks for notnullness of an array (passed by ref)

is_notnull_hash

    Checks for notnullness of an hash (passed by ref)

is_notnull_object

    Checks for notnullness of an object (passed by ref)

stringify_hash

    Turns a hash into a string of keys and values

normalise_utf8

  Normalise any UTF-8 encoding string immediately to exactly what we want
  We want the strict perl utf8 "UTF-8"

inits

   We turn the initials into an array so we can be flexible with them later
   The tie here is used only so we know what to split on. We don't want to make
   any typesetting decisions in Biber, like what to use to join initials so on
   output to the .bbl, we only use BibLaTeX macros.

join_name

  Replace all join typsetting elements in a name part (space, ties) with BibLaTeX macros
  so that typesetting decisions are made in BibLaTeX, not hard-coded in Biber

filter_entry_options

    Process any per_entry option transformations which are necessary

imatch

    Do an interpolating (neg)match using a match RE and a string passed in as variables

ireplace

    Do an interpolating match/replace using a match RE, replacement RE
    and string passed in as variables

validate_biber_xml

  Validate a biber/biblatex XML metadata file against an RNG schema

process_entry_options

    Set per-entry options

parse_date

  Simple parse of ISO8601 dates because not decent module exists for this that
  doesn't default the missing components

biber_decode_utf8

    Perform NFD form conversion as well as UTF-8 conversion. Used to normalize
    bibtex input as the T::B interface doesn't allow a neat whole file slurping.

out

  Output to target. Outputs NFC UTF-8 if output is UTF-8

locale2bcp47

  Map babel/polyglossia language options to a sensible CLDR (bcp47) locale default
  Return input string if there is no mapping

bcp472locale

  Map CLDR (bcp47) locale to a babel/polyglossia locale
  Return input string if there is no mapping
