I'm trying to use oldstyle numbers only in my body text using pdfLaTeX.
Looking at other questions, I had the idea to use the cfr-lm package and then try to come back with lining numbers in : sectioning, figure counters, heads, enumerations, footnotes.
I've done that :
\documentclass[a4paper,12pt,twoside]{book} \usepackage{cfr-lm} \renewcommand{\thechapter}{{\fontfamily{clm}\selectfont\arabic{chapter}}} \renewcommand{\thesection}{{\fontfamily{clm}\selectfont\arabic{chapter}.\arabic{section}}} \renewcommand{\thesubsection}{{\fontfamily{clm}\selectfont\arabic{chapter}.\arabic{section}.\arabic{subsection}}} \renewcommand{\thesubsubsection}{{\fontfamily{clm}\selectfont\arabic{chapter}.\arabic{section}.\arabic{subsection}.\arabic{subsubsection}}} \renewcommand{\theparagraph}{{\fontfamily{clm}\selectfont\arabic{chapter}.\arabic{section}.\arabic{subsection}.\arabic{subsubsection}.\arabic{paragraph}}} \renewcommand{\thesubparagraph}{{\fontfamily{clm}\selectfont\arabic{chapter}.\arabic{section}.\arabic{subsection}.\arabic{subsubsection}.\arabic{paragraph}.\arabic{subparagraph}}} \setcounter{tocdepth}{5} \setcounter{secnumdepth}{5} \begin{document} \chapter{test} \section{test} \subsection{test} \subsubsection{test} \subsubsection{test} \end{document} As I added in the comments, it works for sectioning.
I'm still looking for ideas for the rest.


lmrbyclm.\usepackage{sectsty} \chapterfont{\lstyle} \allsectionsfont{\lstyle}will also get the job done for sectioning headers. (\lstyleis a macro that's provided by thecfr-lmpackage.)
