Biblatex customization not working

Question

I'm working on my assignments for Study and unfortunately I'm too silly to understand the library... Currently the authoryear context is declared:

--> See executable

I already figured out how to change some basic things like the comma in the citation and how to change the url to display without monospace and without prefix. Unfortunately now, the hypenation is damaged and no linefeed is inserted. Here is my code for customizing (file modsBiblatex.tex):

% Optionen für Biblatex
\ExecuteBibliographyOptions{%
giveninits=false,
isbn=true, 
url=true, 
doi=false, 
eprint=false,
maxbibnames=7, % Alle Autoren (kein et al.)
maxcitenames=1, % Kürzel nur aus 1. Autor
backref=false, % Rückverweise auf Zitatseiten
bibencoding=utf8, % wenn .bib in utf8, sonst ascii
bibwarn=true, % Warnung bei fehlerhafter bib-Datei
}%


%Autoren (Nachname, Vorname)
\DeclareNameAlias{default}{last-first}

\renewcommand*{\nameyeardelim}{\addcomma\addspace} % insert a comma between author and year in-text citations


%Titel nicht kursiv anzeigen 
\DeclareFieldFormat{title}{\mkbibquote{#1\isdot}}

% Sourcecode nicht in codecoloumn anzeigen
\DeclareFieldFormat{url}{\url{#1}}
\DeclareFieldFormat{urldate}{#1}

\renewcommand*{\newunitpunct}{\addcomma\space}

% Definiert @Online Eintrag
\DeclareBibliographyDriver{www}{%
  \newunit\newblock
  \printnames{author}%
  \setunit*{\addcomma\space}%
  \newunit\newblock
  \printfield{title}%
  \newunit\newblock
%  \setunit*{\space}%
  \printfield{url}%
  \newunit\newblock
  \setunit*{\addcomma\space accessed \space}%
  \printfield{urldate}%
  \finentry}

The part \DeclareBibliographyDriver is not working for me. I already gave up to find information how to customize this. May someone know a page where this function is explained so a noob like me can understand it? Nethertheless my most important question is: How can I change the url field to include an automatic linebreak again?

Bib example (file economics.bib):

My Questions:
- Do you know any easy documentation for customizing of the bibliography and the drivers?
- Do you know how to get the hypenation in an URL without displaying in monospace? (I need Roman)
- What is the reason, the field urldate and the prefix "accessed" is not displayed?

Could you try with online instead of www in your \DeclareBibliographyDriver? Even though www is indeed defined as an alias of online by biblatex, I'm not sure it expects the alias for the driver definitions. — gusbrs, Aug 17 '17 at 11:56
Don't show snippets, make a complete example that can be tested. Also don't burry too many questions in a long text. The url doesn't break as you removed the \url command in the field format. Use \DeclareFieldFormat{url}{\url{#1}}. — Ulrike Fischer, Aug 17 '17 at 11:59
@UlrikeFischer Thanks alot, this helped to get back the hypenation. But now I'm still figuring the problem the link is displayed in monospace, I want it as Roman, like the rest of the text. May you also got a solution for this? — Gruhl, Aug 17 '17 at 13:13
@gusbrs Thanks for your hint, I changed the bib file to online, but it changed nothing in the result. But I will change my Citavi export to deliver online sources as "online" tag. — Gruhl, Aug 17 '17 at 13:15
Then I guess, as already suggested by Ulrike, that we'll need a minimal working example (MWE) (in your case, a MWEB). That should be compilable code, starting with \documentclass{...} and ending with \end{document}, that illustrates your problem. You can edit your question to include it. — gusbrs, Aug 17 '17 at 13:24
@UlrikeFischer Question has been edited. The command urlstyle worked for me, many thanks! — Gruhl, Aug 17 '17 at 13:36
Please ask only one question per question. It is much easier for us to answer then. There is no shame in asking several questions if they are thought through and provide all the necessary information. — moewe, Aug 17 '17 at 13:56
Regarding bibliography customization, you could take a look at Guidelines for customizing biblatex styles and, of course, biblatex's documentation. — gusbrs, Aug 17 '17 at 13:56
You don't get to see the access date, because your urldate fields are not formatted correctly. Regardless of what you want the output to be, the date input must be in the form YYYY-MM-DD, so only urldate = {2017-08-17} would be correct. — moewe, Aug 17 '17 at 13:57
style=authoryear, citestyle=authoryear, is equivalent to, the shorter style=authoryear. In newer versions of biblatex (>=3.3, current version is 3.7), \DeclareNameAlias{default}{last-first} should be \DeclareNameAlias{default}{family-given}. — moewe, Aug 17 '17 at 13:58
As Ulrike explained \DeclareBibliographyDriver{www} won't work, because @www is just an alias for @online. Internally biblatex only knows online. Biber actually converts all @wwws to @onlines. So you must use \DeclareBibliographyDriver{online} in your customisation code. — moewe, Aug 17 '17 at 14:01
@gusbrs Thanks again. Both I already tryed to understand within the last week, but i did not get it. The biblatex documentation is for me just a syntax sheet, not more. Maybe I can understand it, when I got even more knowledge. In my view, it's nothing for beginners. The Guideline, helped me a bit, but it was too short for the understanding I need to change the Bibliography for the Harvard style. — Gruhl, Aug 17 '17 at 14:01
We don't have the content of your \input{skripte/modsBiblatex}, so we still don't have a code that is compilable from our point of view. Also, I'm not sure what you mean by \DeclareBibliographyDriver "doesn't work", you'll have to be more specific than that. Taking your code (after adjustments) and using \DeclareBibliographyDriver{online} as already suggested here, it does work as intended, in the sense that the formating does follow what's contained there (to see, delete some of the lines, if you wish). — gusbrs, Aug 17 '17 at 14:05
I don't know of any good literature for the 'intermediate' biblatex user that wants to apply modifications and customisations in English. There are some great introductory texts linked in biblatex in a nutshell (for beginners), a few of them cover more than just the basics, but they don't explain all the customisation options. In German there is the classic http://biblatex.dominik-wassenhoven.de/nutzungsbedingungen.shtml?biblatex1 and http://biblatex.dominik-wassenhoven.de/nutzungsbedingungen.shtml?biblatex2 — moewe, Aug 17 '17 at 14:05
... But these articles were written a while ago, and development has moved on a bit since then. So a few things can now be done more easily, a few command names have changed etc. There is also http://texwelt.de/blog/modifizieren-eines-biblatex-stils/ I'm not happy with everything that is done there, but the rough overview is good (https://gitlab.com/Ekkehardt/dok-biblatex-iest is newer and does some things better). — moewe, Aug 17 '17 at 14:08
Many thanks for all of you. I will check the documentations and in the case I cannot manage to change the contents as I need them, I will create a new question. — Gruhl, Aug 17 '17 at 14:16
The options giveninits=false, isbn=true, url=true, are all the default, so you don't have to set them explicitly. — moewe, Aug 17 '17 at 14:17

Mensch · Answer 1 · 2017-09-07T21:53:33.043

At last you have three questions here:

Do you know any easy documentation for customizing of the bibliography and the drivers?

The problem here is what you mean with "easy". I think that is a personal opinion. The "best" documentation is the documentation comming with package biblatex. You can read it with texdoc biblatex from your terminal.
Do you know how to get the hypenation in an URL without displaying in monospace? (I need Roman)

To get the url printed in roman use the command \urlstyle{rm}. To get the hyphenation back use the command \url from package url: \DeclareFieldFormat{url}{\url{#1}}
What is the reason, the field urldate and the prefix "accessed" is not displayed?

You used a wrong date format in your bib entrys, for example urldate = {12.08.2017}. The correct format is yyyy-mm-dd, so please use urldate = {2017-08-12}

I combined your given code snippets to a compilable code and marked all imortant changes with <====== in the code.

gives the result:

Your 4th question is why \DeclareBibliographyDriver{www} is not working. Because www is only an alias, change www to online. It seems that urldate is not propperly defined and so it is not printed with your own driver. A quick workaround could be to change \printfield{urldate}% to use urlday, urlmonth and urlyear instead (change the order as you need):

\DeclareBibliographyDriver{online}{% www <==============================
  \newunit\newblock
  \printnames{author}%
  \setunit*{\addcomma\space}%
  \newunit\newblock
  \printfield{title}%
  \newunit\newblock
  \printfield{url}%
  \newunit\newblock
  \setunit*{\addcomma\space accessed \space}%
  \printfield{urlyear}\printtext{-}\printfield{urlmonth}\printtext{-}\printfield{urlday}% <=================================
  \finentry}

Then you get the following result:

If you define the filed for urldate like this:

\DeclareFieldFormat{urldate}{\addcomma\space\printtext{accessed}\space #1}

you get an comma, then "accessed" and the date in the current form, if you comment out your own driver for online. A driver online is already defined with more functionality than your own.

With a changed bib entry (added editor and note to the first entry) you get the result

with the following MWE:

I think you can do things in a less complicated way than in the other answer (especially in relation to urldate handling).

But there are still a number of confusing points in your original question.

e.g.,

Do you want ‘British’ or “American” style quotes?
Do you want German (12.08.2017) or American (08/12/2017) style short dates?
Do you want all titles enquoted or just ones for online entry types?
Do you really want the date field suppressed in your bibliography? (The date field should contain the date the article was written and urldate, the date you accessed it). I've left it in.

I've also not rewritten the driver as you will lose a lot of functionality and flexibility if you do this. It's better to modify individual bibmacros or clear fields at every bibliography item to tweak your output.
