[Tex/LaTex] Change .bst to put the pages number at the end

Question

My question is simple, but I searched in vain for an answer. Right now, my bibliography style (.bst) gives the following result for an article :

Baumgärtel Hans, « Julius Weisbach und die Einführung der neuen Markscheidekunst in die Praxis », Zeitschrift für Bergbau, Hüttenwesen und verwandteWissenschaften, 13 (1), pp. 371–377, 1961.

I would like to have it with the pages number after the date, so this way :

Baumgärtel Hans, « Julius Weisbach und die Einführung der neuen Markscheidekunst in die Praxis », Zeitschrift für Bergbau, Hüttenwesen und verwandteWissenschaften, 13 (1), 1961, pp. 371–377.

Here's the function, i've tried to work on it, but I really dont understand how it works :

FUNCTION {article}
{ output.bibitem
  format.authors "author" output.check
  author format.key output new.block
  format.title quote "title" output.check
  new.block
  crossref missing$
    { journal emphasize "journal" output.check
      eid empty$

    { format.vol.num.pages output } %
    { format.vol.num.eid output }
  if$
  format.date "year" output.check
}
{ format.article.crossref output.nonnull

  eid empty$
    { format.pages output }
    { format.eid output }
  if$
}
  if$
  format.issn output
  format.doi output
  format.url output
  new.block
  note output
  fin.entry
}

If you can help me, thanks very much in advance …

Save the orignal file abbrvnat.bst in your working directory and rename it to eg. mod-abbrvnat.bst

Now you have to modify two functions: format.vol.num.pages and article:

Here the modifications:

• line 535

  FUNCTION {format.vol.num.pages}
  { volume field.or.null
    number empty$
      'skip$
      { "\penalty0 (" number * ")" * *
        volume empty$
          { "there's a number but no volume in " cite$ * warning$ }
          'skip$
        if$
      }
    if$
    format.date "year" output.check %<-new
    pages empty$
      'skip$
      { duplicate$ empty$
          { pop$ format.pages }
          { ", \penalty0 " * pages n.dashify * }%<-comma new, old :
        if$
      }
    if$
  }
  

• line 700

  FUNCTION {article}
  { output.bibitem
    format.authors "author" output.check
    author format.key output
    new.block
    format.title "title" output.check
    new.block
    crossref missing$
      { journal emphasize "journal" output.check
        eid empty$
          { format.vol.num.pages output }
          { format.vol.num.eid output }
        if$
  %      format.date "year" output.check%<commented
      }
      { format.article.crossref output.nonnull
        eid empty$
          { format.pages output }
          { format.eid output }
        if$
      }
    if$
    format.issn output
    format.doi output
    format.url output
    new.block
    note output
    fin.entry
  }
  

After this modification the following mwe provides:

\documentclass [12pt,a4]{book}
\usepackage[utf8]{inputenc}
\usepackage{natbib}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{Baumgaertel,
 title={Julius Weisbach und die Einführung der neuen Markscheidekunst in die Praxis},
 author={Baumgärtel, Hans},
 journal="Zeitschrift für Bergbau, Hüttenwesen und verwandteWissenschaften",
 volume={13},
 number={1},
 pages={pp~371 -- 377},
 year={1961} 
}
\end{filecontents}
\begin{document}
\cite{Baumgaertel}

\bibliographystyle{mod-abbrvnat}
\bibliography{\jobname}

\end{document}

Please note that more modifications are needed for other cases. I recommend the usage of biblatex.
