This is kind of a combination of two questions and then I have a bibliography style problem on top of that.

I would like to make each bib entry into a hyperlink with the priority: 1. DOI, 2. URL, 3. ISBN/ISNN. It has earlier been shown how this is done for the title of the entries in biblatex: make title hyperlink to DOIs, URL or ISBN. However, I am using a bibliography style which does not show titles (chem-angew). I would like the entire entry to become a hyperlink. This has been done only with DOI in Hyperlink each bib entry to its DOI page.

My first problem is, when I use the chem-angew style and I include an entry with a DOI, the DOI shows, even though I include DOI=false in the usepackage (and the DOI is not supposed to show up in the chem-angew style):

documentclass{article}

usepackage[style=chem-angew,doi=false,url=false,isbn=false,]{biblatex}

usepackage[colorlinks]{hyperref}



begin{filecontents}{jobname.bib}

@article{A01,

author = {Author, A.},

year = {2001},

title = {Alpha},

doi = {doi},

url = {url},

issn = {isbn-issn},

}

end{filecontents}



addbibresource{jobname.bib}

nocite{*}



begin{document}

printbibliography

end{document}

My second problem is, when I add:

AtEveryBibitem{%

  iffieldundef{url}

    {}

    {href{thefield{url}}{usedriver{thefield{article}}}

    csdef{blx@bbx@thefield{entrytype}}{}}%

}

to my local biblatex.cfg file, the bib entry will have the biblatex style and not the chem-angew style as asked for in the same way as my earlier MWE.

The final problem is the priority of the hyperlink which I would like to add to the entries.

Here is one solution that tries to link the entire entry (minus the label). string+doiurl is a simplified version of lockstep's string+doiurlisbn from biblatex: make title hyperlink to DOIs, URL or ISBN

documentclass{article}

usepackage[style=chem-angew,doi=false,url=false,isbn=false,]{biblatex}

usepackage[colorlinks]{hyperref}



newbibmacro{string+doiurl}[1]{%

  iffieldundef{doi}

    {iffieldundef{url}

       {#1}

       {href{thefield{url}}{#1}}}

    {href{https://doi.org/thefield{doi}}{#1}}}



makeatletter

defblx@driver#1{%

  ifcsdef{blx@bbx@#1}

    {usebibmacro{string+doiurl}{csuse{blx@bbx@#1}}}

    {ifcsdef{blx@bbx@*}

       {blx@warning{%

          No driver for entry type '#1'.MessageBreak

          Using fallback driver}%

        usebibmacro{string+doiurl}{csuse{blx@bbx@*}}}

       {blx@error

          {No driver found}

          {I can't find a driver for the entry type

           'abx@field@entrytype'MessageBreak

           and there is no fallback driver either}}}}
