I have one chapter in my latex report which is in French (the other chapters are in English).
I use natbib to generate the bibliography and the citations have the following format when having two authors: Author1 and Author2 (1997).
The issue is that I would like to the change the "and" with "et" (i.e. the French equivalent) in the French chapter, while keeping "and" in the other chapters.
Is it possible to modify citations format for one chapter only? I use the same .bib file for the whole report.
EDIT: I have in the preamble the command AtBeginDocument{\renewcommand{\harvardand}{and}}. So the idea would be to have \renewcommand{\harvardand}{et}} just before the French chapter. However this modifies the whole document, not only the French section. Maybe something can be done by using \ifcase in \renewcommand but I don't know how.
EDIT 2: There is a solution described here, using the command \DeclareRobustCommand{\harvardand}{\IfLanguageName{french}{et}{and}} but for some reason I cannot compile my file using \usepackage[french,english]{babel}. How could I do something similar but instead of IfLanguageName, have something like "IfChapter...etc..."
Many thanks!
