NAME

       "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

       --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|-C
           Sort with "Unicode::Collate" instead of the built-in sort function.  This is the
           default.

       --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".

       --fastsort|-f
           Use Perl's sort instead of "Unicode::Collate" for sorting. Also uses OS locale
           definitions (which may be broken for some languages ...).

       --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-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.

       --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-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-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.  The legacy option --outfile is supported as an alias.

       --output-format=dot|bibtex|biblatexml|bbl
           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.  The legacy option
           --outformat is supported as an alias.

       --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-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.

       --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.

       --sortcase=true|false
           Case-sensitive sorting (default is true).

       --sortgiveninits=true|false
           When sorting names, use only the given name initials, not full given name. Some people
           expect the biblatex giveninits option to do this but it needs to be a separate option
           in case users, for example, need to show only initials but sort with full given names
           (default is false).

       --sortlocale|-l [locale]
           Set the locale to be used for sorting.  With default sorting (--collate|-C), the
           locale is used to add CLDR tailoring to the sort (if available for the locale). With
           --fastsort|-f this sets the OS locale for sorting.

       --sortupper=true|false
           Whether to sort uppercase before lowercase when using default sorting (--collate|-C).
           When using --fastsort|-f, your OS collation locale determines this and this option is
           ignored (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-config
           Schema validate the biber config file.

       --validate-control
           Schema validate the .bcf biblatex control file.

       --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-datamodel|-V
           Validate the data against a data model.

       --version|-v
           Display version number.

       --wraplines|-w
           Wrap lines in the .bbl file.

       --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*).
