[Tex/LaTex] Remove prefix from figure caption in tufte-book document class

captionsfloatstufte

I want to get rid of prefixes in figure captions. I use MikTeX, XeLaTeX and tufte-latex style class. I've tried three variants:

\caption*{Foto}
\usepackage[labelformat=empty]{caption}
\captionsetup[figure]{labelformat=empty}

but no one helped. Am I doing something wrong?
Here's MWE:

\documentclass[nofonts]{tufte-book}

\usepackage{polyglossia}
\setdefaultlanguage{russian}

\usepackage{fontspec}
\setmainfont{Palatino Linotype}

\usepackage{caption}

\begin{document}
\begin{figure}
    \includegraphics[scale=0.75]{square.png}
    \caption{Foto}
\end{figure}
\end{document}

If you want to remove only "Fig." (in Russian "Рис."), then

\makeatletter
\renewcommand{\fnum@figure}{\thefigure}
\makeatother

in the document preamble will print the caption as

1: Foto

If instead you want to get rid also of the number and the colon, a slightly more complicated patch is required: the whole \@caption command must be modified.

\usepackage{etoolbox}
\makeatletter
\patchcmd{\@caption}
  {\noindent\csname fnum@#1\endcsname: \ignorespaces}
  {}
  {}{}
\makeatother

With this code you'll get only

Foto

Here's a complete example:

\documentclass[nofonts]{tufte-book}

\usepackage{polyglossia}
\setdefaultlanguage{russian}

\usepackage{fontspec}
\setmainfont{Palatino}
\newfontfamily{\cyrillicfont}{Palatino}

%%% With this code no name and number will appear
\usepackage{etoolbox}
\makeatletter
\patchcmd{\@caption}
  {\noindent\csname fnum@#1\endcsname: \ignorespaces}
  {}
  {}{}
\makeatother

%%% Remove the above code and uncomment the following
%%% three lines if you still want the number
%\makeatletter
%\renewcommand{\fnum@figure}{\thefigure}
%\makeatother



\begin{document}

\begin{figure}
  \includegraphics[scale=0.75]{square.png}
  \caption{Foto}
\end{figure}

\end{document}

The package caption can't be used because tufte-book redefines the code for captions in an incompatible way.

In case you want no prefix and no number, but still want a list of figures (of course without the numbers), add also the following code before \makeatother:

\pretocmd{\@tufte@lof@line}
  {\begingroup\let\numberline\@gobble}
  {}{}
\apptocmd{\@tufte@lof@line}
  {\endgroup}
  {}{}

The captions in the list will be links to the actual figure.

[Tex/LaTex] change caption in tufte class full-page figure

This is difficult, as tufte-book works really hard to shove your caption in the margin and does not provide any easy way to do proper full page figures with nice full page captions.

What you really need is for the tufte-book people to add this functionality to the class. You could try asking in the tufte-book group on Google groups. But a quick search shows that the same question was asked there in 2010 and no-one has yet answered it.

In the meantime here is my simple hack to work round the problem

replace your \caption tag with this

\stepcounter{figure}
\smallskip\noindent\small Figure \thefigure:
Cena de Acampamento.....

being sure to leave a blank line before the \stepcounter line to force a paragraph break, and not forgetting to remove the } a the end of the caption.

This works by manually updating the counter that \caption uses inside a figure environment. You could make it even more polished by manually writing to the list of figures as well, but if you are that serious about it, you really should think about getting a "full page figure" environment added to tufte-book.

[Tex/LaTex] Caption placement for new float in tufte-book class

Instead of using the newfloat package, you can create the example floating object in a fashion similar to the one used for the tufte classes; this will give you the possibility to automatically inherit the desired formatting. In the following example I defined the example floating object from scratch, using the "tufte way"; the code follows the tufte definitions for figure and table, which can be found in the file tufte-common.def: I also made the necessary provisions for a possible \listofexamples:

\documentclass{tufte-book}
\usepackage{framed, color}
\usepackage{lipsum}

\newcounter{example}[chapter]
\newcommand\examplename{Example}
\newcommand\listexamplename{List of Examples}
\makeatletter
\newcommand\listofexamples{%
  \ifthenelse{\equal{\@tufte@class}{book}}%
    {\chapter*{\listexamplename}}%
    {\section*{\listexamplename}}%
%  \begin{fullwidth}%
    \@starttoc{loe}%
%  \end{fullwidth}%
}
\renewcommand\theexample
     {\ifnum \c@chapter>\z@ \thechapter.\fi \@arabic\c@example}
\def\fps@example{tbp}
\def\ftype@example{1}
\def\ext@example{loe}
\def\fnum@example{\examplename\nobreakspace\theexample}
\newenvironment{example}[1][htbp]
  {\begin{@tufte@float}[#1]{example}{}}
  {\end{@tufte@float}}
\let\l@example\l@figure
\makeatother

\begin{document}

\begin{example}
\caption{Currently, this caption is in the right margin similar to the table caption below.}
\definecolor{shadecolor}{rgb}{1,0.8,0.3}
\begin{shaded}
\lipsum[2]
\end{shaded}
\end{example}

\begin{table}
\caption{This is how I want the new float environment caption to behave.}
\centering
\begin{tabular}{llr}
Column 1 & Column 2 & Column 3 \\
Value A1 & Value A2 & Value A3 \\
\end{tabular}
\end{table}

\end{document}

If you want all your example environments to be with a colored background, you can include the coloring environment directly in the definition of example. The following example illustrates this, but using the mdframed environment (from the mdframed package) instead of shaded (from the framed package); this gives a better vertical alignment between the object and the caption (compare with the example above):

\documentclass{tufte-book}
\usepackage{xcolor}
\usepackage{mdframed}
\usepackage{lipsum}

\definecolor{shadecolor}{rgb}{1,0.8,0.3}

\newcounter{example}[chapter]
\newcommand\examplename{Example}
\newcommand\listexamplename{List of Examples}
\makeatletter
\newcommand\listofexamples{%
  \ifthenelse{\equal{\@tufte@class}{book}}%
    {\chapter*{\listexamplename}}%
    {\section*{\listexamplename}}%
%  \begin{fullwidth}%
    \@starttoc{loe}%
%  \end{fullwidth}%
}
\renewcommand\theexample
     {\ifnum \c@chapter>\z@ \thechapter.\fi \@arabic\c@example}
\def\fps@example{tbp}
\def\ftype@example{1}
\def\ext@example{loe}
\def\fnum@example{\examplename\nobreakspace\theexample}
\newenvironment{example}[1][htbp]
  {\begin{@tufte@float}[#1]{example}{}
    \begin{mdframed}[backgroundcolor=shadecolor,hidealllines=true]}
  {\end{mdframed}\end{@tufte@float}}
\makeatother

\begin{document}

\begin{example}
\caption{Currently, this caption is in the right margin similar to the table caption below.}
\lipsum[2]
\end{example}

\begin{table}
\caption{This is how I want the new float environment caption to behave.}
\centering
\begin{tabular}{llr}
Column 1 & Column 2 & Column 3 \\
Value A1 & Value A2 & Value A3 \\
\end{tabular}
\end{table}

\end{document}
