could the default texdoc configuration for bidi prefer bidi-doc.pdf to bidi.pdf, the latter is the source listing, bidi-doc is the user manual. texdoc -l bidi 1 /usr/local/texlive/2019/texmf-dist/doc/xelatex/bidi/bidi.pdf = Package source documentation 2 /usr/local/texlive/2019/texmf-dist/doc/xelatex/bidi/bidi-doc.pdf = Package user documentation Thanks, David
