Defina bibchecks usando um loop

Question

Estou tentando criar subcategorias para minha bibliografia com títulos por ano (usando biblatex). Descobri que posso usar o defbibcheck para verificar por ano assim:

\defbibcheck{2013}{
  \iffieldint{origyear}
    {\ifnumequal{\thefield{origyear}}{2013}
      {}
      {\skipentry}
    }
    {\iffieldint{2013}
      {\ifnumequal{\thefield{year}}{2013}
       {}
       {\skipentry}
    }
    {\skipentry}
   }
}       

Porém, como há muitos anos, não quero ter uma cópia disso para todos os anos. Eu pensei que poderia usar \foreacho pgfforpacote assim:

\foreach \year in {2012,2013}{%
 \defbibcheck{\year}{
  \iffieldint{origyear}
    {\ifnumequal{\thefield{origyear}}{\year}
      {}
      {\skipentry}
    }
    {\iffieldint{\year}
      {\ifnumequal{\thefield{year}}{\year}
        {}
        {\skipentry}
      }
      {\skipentry}
    }
}
}   

No entanto, os \prinbibliography[check=2013]resultados em Check '2013' not found.Existe outra maneira de fazer isso?

Editar: exemplo mínimo que não funciona abaixo:

\documentclass{article}
\usepackage{filecontents}
\usepackage{pgffor}
\usepackage{biblatex}


\foreach \year in {2012,2013}{%
 \defbibcheck{\year}{
  \iffieldint{origyear}
    {\ifnumequal{\thefield{origyear}}{\year}
      {}
      {\skipentry}
    }
    {\iffieldint{\year}
      {\ifnumequal{\thefield{year}}{\year}
        {}
        {\skipentry}
      }
      {\skipentry}
    }
}
}


\begin{filecontents*}{\jobname.bib}
@inproceedings{Bar2013,
    author = {F. Bar and B. Foo},
    booktitle = {The conference on nothing},
pages = {1--2},
title = {{A meaningless title}},
year = {2013}
}
@inproceedings{Bar2012,
    author = {F. Bar},
booktitle = {International Conference on Information},
pages = {3--4},
title = {{Advanced functionality and performance or nothing }},
year = {2012}
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\begin{document}
\nocite{*}
\printbibliography[check=2013]
\end{document} 

Answer 1

Algo assim?

\begin{filecontents*}{\jobname.bib}
@inproceedings{Bar2011,
    author = {F. Bar and B. Foo},
    booktitle = {The conference 2011 on nothing},
pages = {1--2},
title = {{A meaningless title}},
year = {2011}
}

@inproceedings{Bar2013,
    author = {F. Bar and B. Foo},
    booktitle = {The conference 2013 on nothing},
pages = {1--2},
title = {{A meaningless title}},
year = 2013
}

@inproceedings{Bar2012,
    author = {F. Bar},
booktitle = {International Conference on Information 2012},
pages = {3--4},

    author = {F. Bar and B. Foo},
    booktitle = {The conference on nothing},
pages = {1--2},
title = {{A meaningless title}},

}

    booktitle = {The conference on nothing 2014},
pages = {1--2},
title = {{A meaningless title}},
year = {2014}
}
\end{filecontents*}

Answer 2

Você poderia se adaptarA resposta de Audreyparaum problema muito semelhante (Como dividir a bibliografia em ordem alfabética?).

\makeatletter
\def\ifskipbib{\iftoggle{blx@skipbib}}
\makeatother

\def\yearlist{}
\forcsvlist{\listadd\yearlist}{2010,2011,2012,2013}
\forlistloop{\DeclareBibliographyCategory}{\yearlist}
\renewcommand*{\do}[1]{\defbibheading{#1}{\section*{#1}}}
\dolistloop{\yearlist}
\AtDataInput{\ifskipbib{}{\addtocategory{\thefield{year}}{\thefield{entrykey}}}}

O primeiro bloco de código evita entradas que não aparecem na bibliografia (você não gostaria de ter um 2010 vazio ali).

O segundo bloco percorre todos os anos indicados na segunda linha e cria uma categoria diferente para cada um deles. Em seguida, são definidos os títulos dessas subbibliografias. Finalmente, a última linha corresponde às entradas da categoria do ano.

\documentclass{article}
\usepackage{biblatex}

\begin{filecontents*}{\jobname.bib}
@inproceedings{Bar2013,
    author = {F. Bar and B. Foo},
    booktitle = {The conference on nothing},
pages = {1--2},
title = {{A meaningless title}},
year = {2013}
}
@inproceedings{Bar2012,
    author = {F. Bar},
booktitle = {International Conference on Information},
pages = {3--4},
title = {{Advanced functionality and performance or nothing }},
year = {2012}
}
\end{filecontents*}

\makeatletter
\def\ifskipbib{\iftoggle{blx@skipbib}}
\makeatother

\def\yearlist{}
\forcsvlist{\listadd\yearlist}{2010,2011,2012,2013}
\forlistloop{\DeclareBibliographyCategory}{\yearlist}
\renewcommand*{\do}[1]{\defbibheading{#1}{\section*{#1}}}
\dolistloop{\yearlist}
\AtDataInput{\ifskipbib{}{\addtocategory{\thefield{year}}{\thefield{entrykey}}}}

\addbibresource{\jobname.bib}
\begin{document}
  \nocite{*}
  \printbibheading
  \bibbycategory
\end{document}

Também existe uma versão semiautomática do seu código.

Ao definir um novo comando

\newcommand{\yearcheck}[1]{%
  \defbibcheck{#1}{
    \iffieldint{origyear}
      {\ifnumequal{\thefield{origyear}}{#1}
        {}
        {\skipentry}
      }
      {\iffieldint{year}
        {\ifnumequal{\thefield{year}}{#1}
          {}
          {\skipentry}
        }
        {\skipentry}
      }
   }
}

Pode-se então usar isso para criar bibchecks anuais via

\yearcheck{2012}
\yearcheck{2013}

O que parece não funcionar dentro de um \foeachloop como\foreach \year in {2012,2013} {\yearcheck{\year}}

Ou, muito melhor, através de um loop (graças a @g.kov)

\foreach \year in {2012,2013} {\global\yearcheck{\year}}

A impressão da bibliografia também pode ser implementada através de um loop

\foreach \year in {2012,2013} {\printbibliography[check=\year,title={\year}]}
