"biber" — A bibtex replacement for users of biblatex

Synopsis

biber [options] file[.bcf]
biber [options] --tool <datasource>
Creates "file.bbl" using control file "file.bcf" (".bcf" extension is
optional). Normally use with biblatex requires no options as they are
all set in biblatex and passed via the ".bcf" file
In "tool" mode (see B<--tool> option), takes a datasource (defaults to
"bibtex" datasource) and outputs a copy of the datasource with any command-line
or config file options applied.
Please run "biber --help" for option details

Description

"biber" provides a replacement of the bibtex processor for users of biblatex.

Options

--annotation-marker=[marker]
Sets the suffix which can be appended to a BibTeX data source field name to indicate that the value of the field is a data annotation. The default is "+an".
--cache
If running as a PAR::Packer binary, show the cache location and exit.
--clrmacros
Clears any BibTeX macros (@STRING) between BibLaTeX refsections. This prevents BibTeX warnings about macro redefinitions if you are using the same datasource several times for different refsections.
--collate-options|-c [options]
Options to pass to the "Unicode::Collate" object used for sorting (default is 'level => "4", variable => "non-ignorable"'). See "perldoc Unicode::Collate" for details.
--configfile|-g [file]
Use file as configuration file for "biber". The default is the first file found among biber.conf in the current directory, "$HOME/.biber.conf", or else the output of "kpsewhich biber.conf". In tool mode, (--tool) the biber-tool.conf installed with Biber is always used to set defaults before potentially overriding the defaults with a user-defined config specified with this option. Use the --tool-config option to view the location of the default tool mode config file.
--convert-control
Converts the .bcf control file into html using an XSLT transform. Can be useful for debugging. File is named by appending ".html" to .bcf file.
--decodecharsset=[recode set name]
The set of characters included in the conversion routine when decoding LaTeX macros into UTF-8 (which happens when --bblencoding|-E is set to UTF-8). Set to "full" to try harder with a much larger set or "base" to use a smaller basic set. Default is "base". You may want to try "full" if you have less common UTF-8 characters in your data source. The recode sets are defined in the reencoding data file which can be customised. See the --recodedata option and the PDF manual. The virtual set name "null" may be specified which effectively turns off macro decoding.
--debug|-D
Turn on debugging for "biber".
--dieondatamodel
Exit immediately with error if using "--validate-datamodel" and a datamodel validation error is found. Default is to warn and continue.
--dot-include=section,field,xdata,crossref,xref,related
Specifies the element to include in GraphViz DOT output format if the output format is 'dot'. You can also choose to display crossref, xref, xdata and/or related entry connections. The default if not specified is "--dot_include=section,xdata,crossref,xref".
--fixinits
Try to fix broken multiple initials when they have no space between them in BibTeX data sources. That is, "A.B. Clarke" becomes "A. B. Clarke" before name parsing. This can slightly mess up things like "{U.K. Government}" and other esoteric cases.
--help|-h
Show this help message.
--input-directory [directory]
.bcf and data files will be looked for first in the directory. See the biber PDF documentation for the other possibilities and how this interacts with the "--output_directory" option.
--input-encoding|-e [encoding]
Specify the encoding of the data source file(s). Default is "UTF-8" Normally it's not necessary to set this as it's passed via the .bcf file from biblatex's "bibencoding" option. See "perldoc Encode::Supported" for a list of supported encodings. The legacy option --bibencoding is supported as an alias.
--input-format=bibtex|biblatexml
Biber input format. This option only means something in tool mode (see tool option) since normally the input format of a data source is specified in the .bcf file and therefore from the \addbibresouce macro in BibLaTeX. The default value when in tool mode is 'bibtex'
--isbn10
Force all ISBNs to 10-digit versions on output. This will convert the ISBN internally to an ISBN object which will not have hyphens on output. If you use this option and want an ISBN with hyphens in the correct place on output, use the --isbn-normalise option.
--isbn13
Force all ISBNs to 13-digit versions on output. This will convert the ISBN internally to an ISBN object which will not have hyphens on output. If you use this option and want an ISBN with hyphens in the correct place on output, use the --isbn-normalise option.
--isbn-normalise
Normalise ISBNs with hyphens in the correct places on output.
--logfile [file]
Use file.blg as the name of the logfile.
--listsep=[sep]
Use sep as the separator for BibTeX data source list fields. Defaults to BibTeX's usual 'and'.
--mincrossrefs|-m [number]
Set threshold for crossrefs.
--namesep=[sep]
Use "sep" as the separator for BibTeX data source name fields. Defaults to BibTeX's usual 'and'.
--no-bblxml-schema
When writing bblxml output, don't generate an RNG XML schema from the data model.
--no-bltxml-schema
When reading or writing biblatexml data sources, don't generate an RNG XML schema from the data model.
--noconf
Don't look for a configfile.
--nodieonerror
Don't exit on errors, just log and continue as far as possible. This can be useful if the error is something from, for example, the underlying BibTeX parsing C library which can complain about parsing errors which can be ignored.
--nolog
Do not write any logfile.
--nostdmacros
Don't automatically define any standard macros like month abbreviations. If you also define these yourself, this option can be used to suppress macro redefinition warnings.
--noxname
Disable exended name processing in bibtex data sources. Can be useful if you don't use this and it causes problems due to auto-detection of extended name format.
--onlylog
Do not write any message to screen.
--others-string=[string]
Use string as the final name in a name field which implies "et al". Defaults to BibTeX's usual 'others'.
--output-align
Align field values in neat columns in output. Effect depends on the output format. Default is false. The legacy option --tool_align is supported as an alias.
--output-annotation-marker=[marker]
As --annotation-marker but for tool mode bibtex output. The default is "+an".
--output-directory [directory]
Output files (including log files) are output to directory instead of the current directory. Input files are also looked for in directory before current directory (but after "--input_directory" if that is specified).
--output-encoding|-E [encoding]
Specify the encoding of the output ".bbl" file. Default is "UTF-8". Normally it's not necessary to set this as it's passed via the .bcf file from biblatex's "texencoding" option. See "perldoc Encode::Supported" for a list of supported encodings. The legacy option --bblencoding is supported as an alias.
--output-indent=[num]
Indentation for body of entries in output. Effect depends on the output format. Defaults to 2. The legacy option --tool_indent is supported as an alias.
--output-fieldcase=upper|lower|title
Case for field names output. Effect depends on the output format. Defaults to 'upper'. The legacy option --tool_fieldcase is supported as an alias.
--output-field-order=[field1, ... fieldn]
When outputting bibtex format data in tool mode, this option allows the customisation of the order of fields within entries. The value is a comma-separated string of field names or classes of fields. Fields not mentioned in the list are output in sorted name order after the explicitly specified fields. The classes of fields are:

'names' - All name list fields 'lists' - All non-name list fields 'dates' - All date fields

By default, its value is 'options,abstract,names,lists,dates'.
--output-file|-O [file]
Output to file instead of basename.bbl file is relative to --output_directory, if set (absolute paths in this case are stripped to filename only). file can be absolute if --output_directory is not set. file can be '-' to output directly to STDOUT. The legacy option --outfile is supported as an alias.
--output-format=dot|bibtex|biblatexml|bbl|bblxml
Biber output format. Default if not specified is of course, bbl. Use dot to output a GraphViz DOT file instead of .bbl. This is a directed graph of the bibliography data showing entries and, as requested, sections and fields. You must process this file with "dot", e.g. "dot -Tsvg test.dot -o test.svg" to render the graph. See the --dot_include option to select what is included in the DOT output. bblxml is an XML version of the bbl format which you could transform using XSLT. By default, when outputting bblxml, a RelaxNG XML schema is generated from the active data modeal and saved with a rng extension along with the output file name (unless the --no-bblxml-schema option is specified). You may validate the bblxml using the schema with the --validate-bblxml option. The legacy option --outformat is supported as an alias.
--output-listsep=[sep]
As --listsep but for tool mode bibtex output. Defaults to BibTeX's usual 'and'.
--output-macro-fields=[field1, ... fieldn]
A comma-separated list of field names whose values are, on output, treated as BibTeX macros. Effectively this means that they are not wrapped in braces. Effect depends on the output format. The legacy option --tool_macro_fields is supported as an alias.
--output-namesep=[sep]
As --namesep but for tool mode bibtex output. Defaults to BibTeX's usual 'and'.
--output-resolve
Whether to resolve aliases and inheritance (XDATA, CROSSREF etc.) in tool mode. Defaults to 'false'. The legacy option --tool-resolve is supported as an alias.
--output-safechars
Try to convert UTF-8 chars into LaTeX macros when writing the output. This can prevent unknown char errors when using PDFLaTeX and inputenc as this doesn't understand all of UTF-8. Note, it is better to switch to XeTeX or LuaTeX to avoid this situation. By default uses the --output_safecharsset "base" set of characters. The legacy option --bblsafechars is supported as an alias.
--output-safecharsset=[recode set name]
The set of characters included in the conversion routine for --output_safechars. Set to "full" to try harder with a much larger set or "base" to use a basic set. Default is "base" which is fine for most use cases. You may need to load more macro packages to deal with the results of "full" (Dings, Greek characters, special symbols etc.). The recode sets are defined in the reencoding data file which can be customised. See the --recodedata option and the PDF manual. The legacy option --bblsafecharsset is supported as an alias. The virtual set name "null" may be specified which effectively turns off macro encoding.
--output-xname
When output is a .bib BibTeX file in tool mode, whether to output names the eXtended BibTeX name field format.
--output-xnamesep=[sep]
As --xnamesep but for tool mode bibtex output. Default is '='.
--quiet|-q
Log only errors. If this option is used more than once, don't even log errors.
--recodedata=[file]
The data file to use for the reencoding between UTF-8 and LaTeX macros. It defines the sets specified with the --output_safecharsset and --decodecharsset options. It defaults to recode_data.xml in the same directory as Biber's Recode.pm module. See the PDF documentation for the format of this file. If this option is used, then file should be somewhere "kpsewhich" can find it.
--noskipduplicates
Don't skip duplicate bibliography keys if found. The detection of duplicate keys is done across all data sources. Sometimes you might need duplicates when using several data sources across several refsections in which case you might need to use this option.
--sortdebug
Add comments to output with sorting keys. Useful for debugging.
--sortcase=true|false
Case-sensitive sorting (default is true).
--sortlocale|-l [locale]
Set the locale to be used for sorting. The locale is used to add CLDR tailoring to the sort (if available for the locale).
--sortupper=true|false
Whether to sort uppercase before lowercase when sorting (default is true).
--ssl-nointernalca
Don't try to use the default Mozilla CA certificates when using HTTPS to fetch remote data. This assumes that the user will set one of the perl LWP::UserAgent module environment variables to find the CA certs.
--ssl-noverify-host
Turn off host verification when using HTTPS to fetch remote data sources. You may need this if the SSL certificate is self-signed for example.
--strip-comments
In tool mode, strip all comments from the output file.
--tool
Run in tool mode. This mode is datasource centric rather than document centric. biber reads a datasource (and a config file if specified), applies the command-line and config file options to the datasource and writes a new datasource. Essentially, this allows you to change your data sources using biber's transformation options (such as source mapping, sorting etc.)
--tool-config
Show the location of the default tool mode config file and exit. Useful when you need to copy this file and customise it.
--trace|T
Turn on tracing. Also turns on --debug|d and additionally provides a lot of low-level tracing information in the log.
-u
Alias for --input-encoding=UTF-8
-U
Alias for --output-encoding=UTF-8
--validate-bblxml
Schema validate bblXML output against a schema auto-generated from the BibLaTeX datamodel. The schema will be auto-generated with the name of the .bbl file with a .rng extension. The generated schema can be kept and used with standard XML editors to validate the output during XSL development.
--validate-bltxml
Schema validate BibLaTeXML datasources against a schema auto-generated from the BibLaTeX datamodel. The schema will be auto-generated with the name of the .bcf file with a .rng extension. The generated schema can be kept and used with standard XML editors to validate the datasource during datasource development. The schema validation does not validate all semantic aspects of the datamodel (i.e. the data model constraints)---for this use the "--validate-datamodel" option.
--validate-config
Schema validate the biber config file.
--validate-control
Schema validate the .bcf biblatex control file.
--validate-datamodel|-V
Validate the data against a data model.
--version|-v
Display version number.
--wraplines|-w
Wrap lines in the .bbl file.
--xnamesep=[sep]
Use sep as the separator between namepart names and the namepart values in the eXtended name format. See biber docs. Default is '='.
--xsvsep=[sep]
Use sep as the separator for fields of format type "xsv" in the data model. A Perl regexp can be specified. Defaults to a single comma surround by optional whitespace (\s*,\s*).
