NAME¶
Biber - main module for biber, a bibtex replacement for users of biblatex
SYNOPSIS¶
use Biber;
my $biber = Biber->new();
$biber->parse_ctrlfile("example.bcf");
$biber->prepare;
METHODS¶
new¶
Initialize the Biber object, optionally passing named options as arguments.
display_problems¶
Output summary of warnings/errors before exit
biber_tempdir¶
my $sections= $biber->biber_tempdir
Returns a File::Temp directory object for use in various things
sections¶
my $sections= $biber->sections
Returns a Biber::Sections object describing the bibliography sections
add_sections¶
Adds a Biber::Sections object. Used externally from, e.g. biber
sortlists¶
my $sortlists= $biber->sortlists
Returns a Biber::SortLists object describing the bibliography sorting lists
set_output_obj¶
Sets the object used to output final results
Must be a subclass of Biber::Output::base
get_preamble¶
Returns the current preamble as an array ref
get_output_obj¶
Returns the object used to output final results
set_current_section¶
Sets the current section number that we are working on to a section number
get_current_section¶
Gets the current section number that we are working on
Fakes parts of the control file for tool mode
parse_ctrlfile¶
This method reads the control file
generated by biblatex to work out the various biblatex options.
See Constants.pm for defaults and example of the data structure being built here.
process_setup¶
Place to put misc pre-processing things needed later
Place to put misc pre-processing things needed later for tool mode
resolve_alias_refs¶
Resolve aliases in xref/crossref/xdata which take keys as values to their real keys
We use set_datafield as we are overriding the alias in the datasource
process_citekey_aliases¶
Remove citekey aliases from citekeys as they don't point to real
entries.
nullable_check¶
Check entries for nullable fields
instantiate_dynamic¶
This instantiates any dynamic entries so that they are available
for processing later on. This has to be done before most all other
processing so that when we call $section->bibentry($key), as we
do many times in the code, we don't die because there is a key but
no Entry object.
resolve_xdata¶
Resolve xdata entries
cite_setmembers¶
Promotes set member to cited status
process_interentry¶
$biber->process_interentry
This does several things:
1. Records the set information for use later
2. Ensures proper inheritance of data from cross-references.
3. Ensures that crossrefs/xrefs that are directly cited or cross-referenced
at least mincrossrefs times are included in the bibliography.
validate_datamodel¶
Validate bib data according to a datamodel
Note that we are validating the internal Biber::Entries
after they have been created from the datasources so this is
datasource neutral, as it should be. It is here to enforce
adherence to what biblatex expects.
process_entries_pre¶
Main processing operations, to generate metadata and entry information
This method is automatically called by C<prepare>.
Here we generate the "namehash" and the strings for
"labelname", "labelyear", "labelalpha", "sortstrings", etc.
Runs prior to uniqueness processing
process_entries_post¶
More processing operations, to generate things which require uniqueness
information like namehash
Runs after uniqueness processing
process_singletitle¶
Track seen work combination for generation of singletitle
Track labelname/year combination for generation of extrayear
Track labelname/labeltitle combination for generation of extratitle
Track labeltitle/labelyear combination for generation of extratitleyear
process_sets¶
Postprocess set entries
Checks for common set errors and enforces 'dataonly' for set members
process_labelname¶
Generate labelname information.
process_labeldate¶
Generate labeldate information
process_labeltitle¶
Generate labeltitle
Note that this is not conditionalised on the biblatex "labeltitle"
as labeltitle should always be output since all standard styles need it.
Only extratitle is conditionalised on the biblatex "labeltitle" option.
process_fullhash¶
Generate fullhash
process_namehash¶
Generate namehash
process_pername_hashes¶
Generate per_name_hashes
process_visible_names¶
Generate the visible name information.
This is used in various places and it is useful to have it generated in one place.
process_labelalpha¶
Generate the labelalpha and also the variant for sorting
Generate the extraalpha information
process_presort¶
Put presort fields for an entry into the main Biber bltx state
so that it is all available in the same place since this can be
set per-type and globally too.
process_lists¶
Sort and filter lists for a section
check_list_filter¶
Run an entry through a list filter. Returns a boolean.
generate_sortinfo¶
Generate information for sorting
uniqueness¶
Generate the uniqueness information needed when creating .bbl
create_uniquename_info¶
Gather the uniquename information as we look through the names
What is happening in here is the following:
We are registering the number of occurences of each name, name+init and fullname
within a specific context. For example, the context is "global" with uniquename < 5
and "name list" for uniquename=5 or 6. The keys we store to count this are the most specific
information for the context, so, for uniquename < 5, this is the full name and for
uniquename=5 or 6, this is the complete list of full names. These keys have values in a hash
which are ignored. They serve only to accumulate repeated occurences with the context
and we don't care about this and so the values are a useful sinkhole for such repetition.
For example, if we find in the global context a lastname "Smith" in two different entries
under the same form "Alan Smith", the data structure will look like:
{Smith}->{global}->{Alan Smith} = 2
We don't care about the value as this means that there are 2 "Alan Smith"s in the global
context which need disambiguating identically anyway. So, we just count the keys for the
lastname "Smith" in the global context to see how ambiguous the lastname itself is. This
would be "1" and so "Alan Smith" would get uniquename=0 because it's unambiguous as just
"Smith".
The same goes for "minimal" list context disambiguation for uniquename=5 or 6.
For example, if we had the lastname "Smith" to disambiguate in two entries with labelname
"John Smith and Alan Jones", the data structure would look like:
{Smith}->{Smith+Jones}->{John Smith+Alan Jones} = 2
Again, counting the keys of the context for the lastname gives us "1" which means we
have uniquename=0 for "John Smith" in both entries because it's the same list. This also works
for repeated names in the same list "John Smith and Bert Smith". Disambiguating "Smith" in this:
{Smith}->{Smith+Smith}->{John Smith+Bert Smith} = 2
So both "John Smith" and "Bert Smith" in this entry get uniquename=0 (of course, as long as
there are no other "X Smith and Y Smith" entries where X != "John" or Y != "Bert").
generate_uniquename¶
Generate the per-name uniquename values using the information
harvested by create_uniquename_info()
create_uniquelist_info¶
Gather the uniquename information as we look through the names
generate_uniquelist¶
Generate the per-namelist uniquelist values using the information
harvested by create_uniquelist_info()
Generate information for:
* extraalpha
* extrayear
* extratitle
* extratitleyear
generate_singletitle¶
Generate the singletitle field, if requested. The information for generating
this is gathered in process_singletitle()
sort_list¶
Sort a list using information in entries according to a certain sorting scheme.
Use a flag to skip info messages on first pass
prepare¶
Do the main work.
Process and sort all entries before writing the output.
Do the main work for tool mode
fetch_data¶
Fetch citekey and dependents data from section datasources
Expects to find datasource packages named:
Biber::Input::<type>::<datatype>
and one defined subroutine called:
Biber::Input::<type>::<datatype>::extract_entries
which takes args:
1: Biber object
2: Datasource name
3: Reference to an array of cite keys to look for
and returns an array of the cite keys it did not find in the datasource
get_dependents¶
Get dependents of the entries for a given list of citekeys. Is called recursively
until there are no more dependents to look for.
remove_undef_dependent¶
Remove undefined dependent keys from an entry using a map of
dependent keys to entries
_parse_sort¶
Convenience sub to parse a .bcf sorting section and return nice
sorting object
_filedump and _stringdump¶
Dump the biber object with Data::Dump for debugging
