[Tex/LaTex] Achieve Linebreak in DOI in biblatex

biblatexdoiline-breakingxetex

In my references (using XeLaTeX, biblatex and Biber) I have one specific DOI that is hanging over more than a centimeter after line-break.

All other DOI are correctly wrapped. Even inserting a (wrong space in the DOI does not help at all). How can I fix that?

I invoke biblatex using:

 \usepackage[safeinputenc,uniquelist=false,maxnames=2,%
             minnames=1,maxbibnames=99,style=authoryear,url=false,%
             dashed=false,firstinits=true,backend=biber]{biblatex}

and hyperref sign:

\usepackage[hidelinks,pdfa,pdfencoding=auto,pdfusetitle,hypertexnames=false]{hyperref}

This is what it looks like:

P.S.: I know I can use:
\setcounter{biburlnumpenalty}{100}
but I'd prefer to perform a manual linebreak using some trick

You can reset the break penalty for specific bibliography entries. Examples can be found here: Avoiding inelegant splits on URLs and Biblatex breakline Doi

Breaks in name parts are controlled by the lownamepenalty and highnamepenalty counters. Details can be found in biblatex.def. These penalties default to no more than \hyphenpenalty, which is normally very low. None of the penalties are reset. For URLs definitions are hooked into \bibsetup and \citesetup. Other penalties are defined globally.

[Tex/LaTex] Biblatex: Convert doi-url into doi field

If biber is used as backend, then one can use the \DeclareSourcemap facilities to change fields.

For the case at hand a solution is to remap url entries with dx.doi.org as initial part using the following code:

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[ % copies url to doi field if it starts with http://dx.doi.org/
        fieldsource=url,
        match=\regexp{http://dx.doi.org/(.+)},
        fieldtarget=doi,
      ]
    \step[ % removes http://dx.doi.org/ string from doi field
      fieldsource=doi,
      match=\regexp{http://dx.doi.org/(.+)},
      replace=\regexp{$1}
    ]
    }
  \map{ % removes url + urldate field from all entries that have a doi field
   \step[fieldsource=doi, final]
   \step[fieldset=url, null]
   \step[fieldset=urldate, null]
   }
 }
}

The actual value inside \regexp can be adjusted.

In the first step we create a doi field for each entry where the url field matches the regexp, and the novel field has the value of the url field. In the second step we remove the doi "namespace".

In the second \map sequence the url and urldate fields are cleared if a doi field is present, to mimic the behavior in the first part of the original question.

[Tex/LaTex] Citing (author, journalabbr., year) needed

First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.

Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.

Last but not least you have to add the abbreviation fields to the entries.

MWE:

\begin{filecontents}{min.bib}
@article{boisson2003unexpected,
  title={Unexpected protein families including cell defense components feature in the N-myristoylome of a higher eukaryote},
  author={Boisson, B. and Giglione, Carmela and Meinnel, Thierry},
  journal={Journal of Biological Chemistry},
  journalabbr={JBC},
  year={2003},
  publisher={ASBMB}

\end{filecontents}

\begin{filecontents}{authorjabbryear.dbx}

\DeclareDatamodelEntryfields[article]{journalabbr}

        }%

    {\usebibmacro{cite:shorthand}}}

\addbibresource{min.bib}

\begin{document}

\citep{boisson2003unexpected} 

How it should look like: 

(Boisson et al., JBC, 2003)

\printbibliography

\end{document}
