SYNOPSIS

pdf-lbr-output-bib --version pdf-lbr-output-bib --help|-h

pdf-lbr-output-bib [ --clipboard|-c ] [ --max-authors|-m count [ --only-first-author|-f ] ] [ --filter|-F [type:]field[?iffield|!ifnotfield...]=spec ... ] [ --no-default-filter|-N ] [ --abbreviate|-a scheme ... ] [ --output-text-format|-o type=<format> ... | --output-text|-O | --pdf-file-comment|-P ] files|directories ...

... files|directories ... | pdf-lbr-output-bib ...

DESCRIPTION

pdf-lbr-output-bib reads BibTeX bibliographic metadata embedded in PDF files and/or any PDF files in directories. If files|directories are not given on the command line, they are read from standard input, one per line.

The BibTeX metadata is then printed to standard output; if --clipboard is given, it is instead copied to the clipboard.

OPTIONS

--max-authors|-m count [ --only-first-author|-f ]

If the number of authors is greater than count, and

• If --only-first-author is given, output only the first author, followed by "and others".

• Otherwise, output the first count authors, followed by "and others".

--filter|-F [type:]field[?iffield|!ifnotfield...]=spec ... [ --no-default-filter|-N ]

Apply the filter spec to the BibTeX field. If given, type applies filter only to BibTeX entries of that type, iffield applies filter only to BibTeX entries where <iffield> is defined, and ifnotfield applies filter only to BibTeX entries where <ifnotfield> is not defined. Possible spec are:

d

Exclude field from output.

=value

Set field to value in output.

s/pattern/replacement[/pattern/replacement...]/

Replace each regular expression pattern with replacement in output.

If no --filter arguments are given, default filters given in the configuration file are applied (unless --no-default-filter is given).

--abbreviate|-a scheme ...

Abbreviate journal/series titles according to the given scheme, applied in the order given on the command line. Available schemes:

aas

AAS macros for astronomy journals, used by the NASA Astrophysics Data System.

iso4

ISO4 abbreviations using the ISSN List of Title Word Abbreviations.

iso4~

Same as iso4 but separate words with tildes instead of spaces.

--pdf-file-comment|-P

If true, output the PDF filename as a comment before each BibTeX entry. Default is false. (The PDF filename is never included in the BibTeX entry itself.)

--output-text-format|-o type=<format>

Instead of outputting a BibTeX entry, output plain text, formatting entries of type type with format format. BibTeX fields may be substituted into format with the syntax %field.

The author and editor fields must include one of the suffixes :fvlj or :vljf to indicate the citation style: author:fvlj cites authors with initials then last name; author:vljf cites authors with last name then initials.

Format text surrounded by curly braces is removed if it contains a % from an unexpanded field. Curly braces may be nested to define alternatives for missing fields, e.g. {DOI:%doi{URL:%url}} provides a URL only if the DOI field is missing.

--output-text|-O

Instead of outputting a BibTeX entry, output plain text, formatting entries with formats given in the configuration file.
