Disable backref printing with fullcite

Question

Consider the following MWE

\documentclass{article}
\usepackage[style=authoryear-comp,backend=biber,backref=true]{biblatex}
\addbibresource{biblatex-examples.bib}

\newbibmacro*{mypageref}{%
\addperiod
  \iflistundef{pageref}
    {}
    {\printtext[brackets]{%
      \ifnumgreater{\value{pageref}}{1}
        {\bibstring{backrefpages}\ppspace}
    {\bibstring{backrefpage}\ppspace}%
      \printlist[pageref][-\value{listtotal}]{pageref}}}}
\renewbibmacro{pageref}{}

\renewbibmacro{finentry}{%
  \setunit{\bibpagerefpunct}\newblock
  \usebibmacro{mypageref}%
  \finentry}

\begin{document}
\fullcite{knuth:ct:e}
\printbibliography
\end{document}

This allows the backrefs to be formatted the way I want them (between brackets, etc) but it also prints the backref with the \fullcite command. How can I disable backref in the body of the document when using \fullcite while preserving backref (and formatting) in the bibliography?

Answer 1

While in theory, it would be possible to check whether we're in a cite command, or in the bibliography (with \ifcitation and \ifbibliography, pp. 185-186 of the biblatex documentation, that is not really necessary here, as we can just modify the pageref macro to do what you want (there is no need for a new mypageref) and use the full stop to separate the pagerefs from the rest of the bibliography entry.

\renewcommand{\bibpagerefpunct}{\addperiod\space}
\renewbibmacro*{pageref}{%
  \iflistundef{pageref}
    {}
    {\printtext[brackets]{%<--- here we had parens before
       \ifnumgreater{\value{pageref}}{1}
         {\bibstring{backrefpages}\ppspace}
         {\bibstring{backrefpage}\ppspace}%
       \printlist[pageref][-\value{listtotal}]{pageref}}}}

The standard pageref is not used in \fullcites, so we're fine, here.

MWE

\documentclass{article}
\usepackage[style=authoryear-comp,backend=biber,backref=true]{biblatex}
\addbibresource{biblatex-examples.bib}

\renewcommand{\bibpagerefpunct}{\addperiod\space}
\renewbibmacro*{pageref}{%
  \iflistundef{pageref}
    {}
    {\printtext[brackets]{%
       \ifnumgreater{\value{pageref}}{1}
         {\bibstring{backrefpages}\ppspace}
         {\bibstring{backrefpage}\ppspace}%
       \printlist[pageref][-\value{listtotal}]{pageref}}}}

\begin{document}
\fullcite{knuth:ct:e}
\printbibliography
\end{document}
