I'm having trouble getting latexdiff to work when using the biblatex citation commands \parencite and \textcite.
Take old.tex:
\documentclass[a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{filecontents}
\begin{filecontents}{bibliography.bib}
@article{greenwade93,
author = "George D. Greenwade",
title = "The {C}omprehensive {T}ex {A}rchive {N}etwork ({CTAN})",
year = "1993",
journal = "TUGBoat",
volume = "14",
number = "3",
pages = "342--351"
}
@book{goossens93,
author = "Michel Goossens and Frank Mittelbach and Alexander Samarin",
title = "The LaTeX Companion",
year = "1993",
publisher = "Addison-Wesley",
address = "Reading, Massachusetts"
}
\end{filecontents}
\usepackage[style=apa,backend=biber]{biblatex}
\addbibresource{bibliography.bib}
\begin{document}
\textcite{greenwade93} is the best article on \LaTeX \parencite{goossens93}.
\printbibliography
\end{document}
and new.tex:
\documentclass[a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{filecontents}
\begin{filecontents}{bibliography.bib}
@article{greenwade93,
author = "George D. Greenwade",
title = "The {C}omprehensive {T}ex {A}rchive {N}etwork ({CTAN})",
year = "1993",
journal = "TUGBoat",
volume = "14",
number = "3",
pages = "342--351"
}
@book{goossens93,
author = "Michel Goossens and Frank Mittelbach and Alexander Samarin",
title = "The LaTeX Companion",
year = "1993",
publisher = "Addison-Wesley",
address = "Reading, Massachusetts"
}
\end{filecontents}
\usepackage[style=apa,backend=biber]{biblatex}
\addbibresource{bibliography.bib}
\begin{document}
\textcite{goossens93} is the best book on \LaTeX \parencite{greenwade93}.
\printbibliography
\end{document}
Running latexdiff old.tex new.tex > diff.tex gives:

which, when compiled with pdflatex yields:
The problem is that latexdiff puts the markup commands within the \textcite command, which obvious doesn't work. Adding natbib=true to the biblatex options and changing \textcite to \citet and \parencite to \citep gives the correct output:
The documentation (section 4) says:
The following packages trigger special behaviour:
...
apacite, biblatex
Redefine the commands recognised as citation commands.
Is this a bug in latexdiff or am I missing something?
I'd be happy to use the natbib commands instead, but I am using the code from this answer to to include the author name in the hyperlink.
EDIT: turns out that the code from moewe to include the author(s) in the citation links works perfectly fine when using the natbib command instead of the standard biblatex ones. I have no idea how that works, but it solves my immediate problem.
latexdiffdoes not detectbiblatexcorrectly or it detects it correctly, but does not handle its commands correctly. In either case I'd say this is a bug or limitation ofbiblatex. I suggest you contact the author about this. – moewe Jul 26 '20 at 19:41latexdiff. Indeed it is; or better was - I just fixed it on the github repository. So the answer is either use the master from github repository of latexdiff or wait for the next release. – frederik Jul 27 '20 at 16:34biblatexway too often. Sorry for the confusion. Thanks for catching that. – moewe Jul 27 '20 at 18:04
