Biber::Input::file::bibtex(3)

  init_cache
    Invalidate the T::B object cache. Used only in tests when e.g. we change the encoding
    settings and therefore must force a re-read of the data

  TBSIG
     Signal handler to catch fatal Text::BibTex SEGFAULTS. It has bugs
     and we want to say at least something if it coredumps

  extract_entries
   Main data extraction routine.
   Accepts a data source identifier, preprocesses the file and then
   looks for the passed keys, creating entries when it finds them and
   passes out an array of keys it didn't find.

  create_entry
   Create a Biber::Entry object from a Text::BibTeX object
   Be careful in here, all T::B set methods are UTF-8/NFC boundaries
   so be careful to encode(NFC()) on calls. Windows won't handle UTF-8
   in T::B btparse gracefully and will die.

  cache_data
   Caches file data into T::B objects indexed by the original
   datasource key, decoded into UTF8

  preprocess_file
   Convert file to UTF-8 and potentially decode LaTeX macros to UTF-8

  parse_decode
  Partially parse the .bib datasource and latex_decode the data contents.
  We do this because latex_decoding the entire buffer is difficult since
  such decoding is regexp based and since braces are used to protect data in
  .bib files, it makes it hard to do some parsing.

  parsename
    Given a name string, this function returns a Biber::Entry::Name object
    with all parts of the name resolved according to the BibTeX conventions.

    parsename('John Doe', 'author', 'key')
    returns an object which internally looks a bit like this:

    { given          => {string => 'John', initial => ['J']},
      family         => {string => 'Doe', initial => ['D']},
      prefix         => {string => undef, initial => undef},
      suffix         => {string => undef, initial => undef},
      id             => 32RS0Wuj0P,
      strip          => {'given'  => 0,
                         'family' => 0,
                         'prefix' => 0,
                         'suffix' => 0}
      }

  parsename_x
    Given a name string in extended format, this function returns a Biber::Entry::Name object
    with all parts of the name resolved according to the BibTeX conventions.

    parsename_x('given=John, family=Doe')
    returns an object which internally looks a bit like this:

    { given          => {string => 'John', initial => ['J']},
      family         => {string => 'Doe', initial => ['D']},
      prefix         => {string => undef, initial => undef},
      suffix         => {string => undef, initial => undef},
      id             => 32RS0Wuj0P,
      hashid         => 'someid',
      sortingnamekeytemplatename => 'template name',
    }
