[Tex/LaTex] Formatting issue with DeclareBibliographyDriver in the Custom Biblatex Style based

biblatex

Following my initial problems about the creation of a new style as well as my first try which ended in an error with the cite, I've created a new BBX/CBX combo.

So I'm progressing, I chose option 2 from my last post, I took the authortitle-terse as a base and copy-pasted it in my own style, then made some small changes. The code is below.

In short, neither my "book" nor my "thesis" driver definition are working. Here are my issues:

1) Book

Delimiter are completely off
The case for multiple authors is not consistent, it seems the driver do not recognize family and given name
There is an extra "," between family and first name
Moreover, I could not code this requirement : if the label field is set, there should be an extra text after the bibliography which says (cité : all author family names in small caps separated by "/"-field

Example for the first cite :
Druey Jean-Nicolas, Titre au hasard ,2e éd., Berne 2016 (cité : Druey-Titre)

2) Thesis

There are " between the title
The title is not in italic
There is an extra "," between first and family name
The separation for block and unit seems way off from my need…

3) Language not detected

I had to force the recnognition of the language. It was not automatically taken.
This caused some real pain, as I only noticed that the issue after adding the "edition" field, noticing that it was in English.

Best Answer

`@book`

In general you don't want to change \newblockpunct you need to change \newunitpunct
The parser recognises the names correctly, you want
```
 \DeclareNameAlias{sortname}{family-given}
```
You need
```
 \renewcommand*{\revsdnamepunct}{}
```
See below

`@thesis`

Your main problem was that you had an \endinput after the driver for @book. That line caused biblatex to ignore everything after it, so the @thesis driver was never read.

With

\DeclareFieldFormat*{title}{\mkbibemph{#1}}
\DeclareFieldFormat*{citetitle}{\mkbibemph{#1}}

you get all titles in italics without quotation marks.

Language not detected

Your MWE detected the French language just fine for me without language=french. If you use really ancient versions of biblatex or polyglossia that could be problematic, but with a fairly modern version, you should be fine.

The citation style

The label field is only added if there are two works by the same authors. And only then you get to see 'cité' in the bibliography.

The styles are already equipped to do that for us, we only need

\DeclareLabeltitle{%
  \field{label}
  \field{shorttitle}
  \field{title}
  \field{maintitle}
}

and two macros to print the 'cité' information in the bibliography

[Tex/LaTex] BibLaTex custom style – header

You can often avoid modifying each individual bibliography driver by applying edits to the bibliography macros instead. In the standard styles the begentry bibiliography macro appears at the beginning of every driver. This is a good place to add the item "header".

Standard drivers typically print publishing information in the form <location>: <publisher>. For most entry types this order can be swapped by editing the publisher+location+date bibliography macro.

The rest of the problem is handled with edits to biblatex's delimiter/punctuation commands and name formats. Here's an example.

\documentclass{article}
\usepackage[backend=bibtex,style=authortitle,firstinits,terseinits]{biblatex}

\renewbibmacro*{begentry}{%
  \renewcommand*{\finalnamedelim}{\multinamedelim}%
  \renewcommand*{\multinamedelim}{\addspace\slash\space}%
  \printtext[bold]{%
    \printnames{labelname}%
    \setunit*{\addspace}%
    \printfield{year}}%
  \setunit*{\par\nobreak}
  \renewcommand*{\multinamedelim}{\addsemicolon\space}}

\renewbibmacro*{publisher+location+date}{%
  \printlist{publisher}%
  \setunit*{\addcomma\space}%
  \printlist{location}%
  \setunit*{\addcomma\space}%

[Tex/LaTex] Custom Biblatex reference style

You ask several things in the question. Here is my proposed solution, with an explanation following.

Sample output

\documentclass{article}

\usepackage{xstring}
\usepackage[style=alphabetic,maxbibnames=99]{biblatex}
\addbibresource{ref.bib}

\DeclareLabelalphaTemplate{
  \labelelement{
    \field[strwidth=4,strside=left,names=1,lowercase]{labelname}
    }
  \labelelement{
    \field[strwidth=2,strside=right]{year}
    }
}

\renewcommand{\labelalphaothers}{}

\DeclareFieldFormat{labelalpha}{\textsc{\padded{#1}}}
%\DeclareFieldFormat{extraalpha}{\textsc{\mknumalph{#1}}}

\newcommand{\padded}[1]{\begingroup%
\expandarg\StrGobbleRight{#1}{2}[\mystr]%
\StrLeft{\mystr \textunderscore\textunderscore\textunderscore\textunderscore}{4}%
\StrRight{#1}{2}%
\endgroup}

\begin{document}

\cite{one,oneo,two,three,four}
\printbibliography

\end{document}

with ref.bib given at the end of my answer.

Firstly, the alphabetic style is the closest to the one you request and is modifiable via the \DeclareLabelalphaTemplate. The code above pulls off up to four characters from the last name of the first author, adds to the two final digits of the year, and final a letter to disambiguate if necessary. We make the letters lowercase in preparation for makeing them small caps.

The command setting \labelalphaothers to null, ensures that no + sign is added when there are several authors.

The formatting of the labels as small caps is acheived via changing the field format of labelalpha. This is the part of the label up to and including the year digits, but not the disambiguation letter. If you want that in small caps then uncomment the line with extraalpha.

Now I use the xstring package to deal with the padding issue via a command \padded. We pull off the year, add on underscores and take just the first four characters. Then we put the year back on. The \expandarg command ensures that only \mystring gets expanded in the argument to \StrLeft, expanding the underscores would give problems.
