% \bibsetup is a generic hook controlling the (low-level) layout of
% the bibliography and bibliography lists. The default
% definition should work fine in most cases.
% There are a few other penalties and parameters that could be adjusted
% here, but we don't do that by default for backwards compatibility
% reasons.
% * \finalhyphendemerits can be set to 0 to allow hyphenation
%   in the penultimate line

\newcommand*{\bibsetup}{%
  \interlinepenalty=5000\relax
  \widowpenalty=10000\relax
  \clubpenalty=10000\relax
  \raggedbottom
  \frenchspacing
  \biburlsetup}

% The penalties above are not specific to biblatex. These are
% low-level TeX features. \interlinepenalty is the penalty assigned
% to page breaks within a paragraph (i.e., in this case, a
% bibliography entry); \clubpenalty is an additional penalty
% assigned to page breaks after the first line of a paragraph;
% \widowpenalty is an additional penalty assigned to page breaks
% before the last line of a paragraph. Note that the value 10000
% means 'infinite' as far as TeX is concerned. Setting a penalty to
% 10000 will unconditionally suppress the respective breakpoint.
%
% The net effect of the above settings is as follows. Breaking a
% bibliography entry across pages is discouraged, but not suppressed
% altogether. If a bibliography entry spans less than four lines,
% TeX will always keep it on one page. If it spans four or more
% lines, it may be broken across pages, provided that there are at
% least two lines on the page before and after the break.
%
% These penalties should normally be used in conjunction with
% \raggedbottom. If you don't like that and remove \raggedbottom
% from the definition of \bibsetup, make sure to provide some
% stretchability between bibliography entries by setting \bibitemsep
% to a suitable value, e.g.:
%
% \setlength{\bibitemsep}{0.5\baselineskip plus 0.5\baselineskip}
%
% Using \frenchspacing in the bibliography is recommended. If you
% want more visual separation, try the package option 'block=space'.
% This will yield better results than \nonfrenchspacing.

% If \frenchspacing is removed here, it may also have to be removed
% from \blx@beglang@spacefactors, for example with
% \let\blx@beglang@spacefactors\@empty

% \citesetup is a generic hook for citations.

% Miscellaneous facilities
% ------------------------------------------------------------------

% The counter 'abbrvpenalty' holds the penalty used in short or
% abbreviated bibliography strings. For example, a linebreak in
% expressions such as "et al." or "ed. by" is unfortunate, but should
% still be possible to prevent overfull boxes. We use TeX's
% \hyphenpenalty (normally 50) as the default value. The idea is
% making TeX treat the whole expression as if it were a single,
% hyphenatable word as far as line-breaking is concerned. If you
% dislike such linebreaks, use a higher value. If you do not mind
% them at all, set this counter to zero. If you want to suppress them
% unconditionally, set it to 10000.
\defcounter{abbrvpenalty}{\hyphenpenalty}

% The counter 'highnamepenalty' also holds a penalty affecting the
% line-breaking of names. This penalty is inserted between smaller
% chunks of a name, for example between the first and the middle
% name. The default value is \hyphenpenalty. If you dislike such
% linebreaks, use a higher value. If you do not mind them at all,
% set this counter to zero. If you prefer the traditional BibTeX
% behavior, set it to 10000.
\defcounter{highnamepenalty}{\hyphenpenalty}

% The counter 'lownamepenalty' holds a penalty which affects the
% line-breaking of names. This penalty is inserted between larger
% chunks of a name, for example between the chunk consisting of all
% first names and the last name. The default value is half the
% \hyphenpenalty. If you dislike such linebreaks, use a higher
% value. If you do not mind them at all, set this counter to zero.
\defcounter{lownamepenalty}{\hyphenpenalty/2}

% Note that default values assigned to the above counters are
% deliberately very low to prevent overfull boxes. This implies that
% you will hardly notice any effect on line-breaking if the text is
% set justified. If you set these counters to 10000 to suppress the
% respective breakpoints, you will notice their effect but you may
% also be confronted with overfull boxes. Keep in mind that
% line-breaking in the bibliography is often more difficult than in
% the body text and that you can not resort to rephrasing a
% sentence. In some cases it may be preferable to set the entire
% bibliography \raggedright (by modifying \bibsetup) to prevent
% suboptimal linebreaks. In this case, even the very low default
% penalties will make a visible difference.

% When generating an index entry, we need to test which parts of a
% name are actually available to prevent spurious punctuation and
% spaces.
%
% Note that the standard LaTeX \index command simply writes its
% argument to the .idx file without preventing expansion. This means
% that all \ifblank etc. tests are expanded on the way and will not end
% up in the index. The index package, however, prevents expansion.
% This would lead to \ifblank etc. ending up in the .idx file. To avoid
% that, we preprocess the index entry inside an \edef. We use
% \unexpanded to protect the \index command and the actual data from
% expansion. This definition will work with both index.sty and the
% standard indexing facilities.
%
% We also use \ifuseprefix to ensure that the name prefix is handled
% properly. \actualoperator is the so-called actual operator, as
% defined by the 'actual' specifier in the .ist file. The makeindex
% program will use the part preceeding the \actualoperator
% delimiter for sorting. The part after the delimiter is used as the
% index is printed. Note that this is not specific to biblatex, see
% the makeindex documentation for details.
