[Tex/LaTex] Regarding the leftbar environment

framed

Does anyone know how to control the width and color of the left bar in the leftbar environment?

Best Answer

Ignore the optional argument:

\documentclass{article}
\usepackage{xcolor}
\usepackage{framed}

\renewenvironment{leftbar}[1][\hsize]
{%
    \def\FrameCommand
    {%
        {\color{red}\vrule width 3pt}%
        \hspace{0pt}%must no space.
        \fboxsep=\FrameSep\colorbox{yellow}%
    }%
    \MakeFramed{\hsize#1\advance\hsize-\width\FrameRestore}%
}
{\endMakeFramed}

\def\fact{It is practically a big lie that LaTeX makes you focus on the content without bothering about the layout.}
\begin{document}
\fact
\leftbar
\fact
\endleftbar
\fact
\end{document}

Specify the optional argument:

You can specify the optional argument as the following example:

\documentclass{article}
\usepackage{xcolor}
\usepackage{framed}

\renewenvironment{leftbar}[1][\hsize]
{%
    \def\FrameCommand
    {%
        {\color{red}\vrule width 3pt}%
        \hspace{0pt}%must no space.
        \fboxsep=\FrameSep\colorbox{yellow}%
    }%
    \MakeFramed{\hsize#1\advance\hsize-\width\FrameRestore}%
}
{\endMakeFramed}

\def\fact{It is practically a big lie that LaTeX makes you focus on the content without bothering about the layout.}
\begin{document}
\fact
\leftbar[0.75\linewidth]
\fact
\endleftbar
\fact
\end{document}

[Tex/LaTex] Making \footnote work in leftbar environment

A slightly longer code, which allows you to only type \footnote. The idea is to make each footnote append \footnotetext{#1} to a token list. This token list is then typeset at the right place. Some trickery is required to get nesting right, as well as hyperref support. Normally, this can be used for other (non-verbatim-ish) environments.

Comments in the code.

\documentclass{article}
\usepackage{etoolbox} % for "\pretocmd".
\makeatletter
%
% User command, see the end of the preamble for use.
% We redefine the environment by adding "\savefoot@begin" at 
% the beginning, and "\savefoot@end" at the end.
%
\newcommand{\DeclareSavefootEnvironment}[1]{%
  \expandafter\pretocmd\csname #1\endcsname
              {\savefoot@begin}{}{\savefoot@patch@error{#1}}%
  \expandafter\pretocmd\csname end#1\endcsname
              {\savefoot@end}{}{\savefoot@patch@error{#1}}%
}
\newcommand{\savefoot@patch@error}[1]{%
  \PackageError{savefoot}{etoolbox failed to patch the environment #1, sorry}{}}
%
% Register allocation.
%
\newcount\c@savefoot@depth
\newtoks\savefoot@toks
%
% "\savefoot@begin" starts an environment which saves footnotes.
% We only want to output footnotes outside any such environment,
% so we count how deep we are in this kind of environment using
% the count "\c@savefoot@depth", which pretends to be a LaTeX
% counter. 
%
% We will store all the "\footnotetext" into the toks 
% "\savefoot@toks". This is initialized _locally_ at the start
% of each "savefoot" environment.
% 
\newcommand{\savefoot@begin}{%
  \advance\c@savefoot@depth by 1\relax  
  \savefoot@toks={}}
%
% When ending a savefoot environment, we check if it was the 
% outermost one. In that case, "\@secondoftwo", we output the
% "\footnotetext" that we saved, after the end of the group.
% The "\endgroup" must be explicitly there; this is the case
% because of how "\end{...}" works in LaTeX2e.
% 
% Since the register "\savefoot@toks" is restored at the end 
% of the group, we need to expand it inside the group, then 
% send "\savefoot@append{<expanded \savefoot@toks>}" after the
% "\endgroup", hence the "\expandafter"s. Same thing when we 
% need to typeset.
% 
\newcommand{\savefoot@end}{%
  \ifnum\c@savefoot@depth>\@ne
  \expandafter\@firstoftwo
  \else
  \expandafter\@secondoftwo
  \fi
  {% Nested, don't output, save to the level above.
    \expandafter\do@after@explicit@endgroup\expandafter{%
      \expandafter\savefoot@append\expandafter{\the\savefoot@toks}}%
  }%
  {% Outside, output.
    \expandafter\do@after@explicit@endgroup\expandafter{%
      \the\savefoot@toks}%
  }%
}
%
% Appending to a toks is standard.
%
\newcommand{\savefoot@append}[1]{%
  \savefoot@toks\expandafter{\the\savefoot@toks#1}}%
%
% To put after "\endgroup", we need delimited parameters,
% hence the "\def". We first check that the command is new,
% just in case.
% 
\newcommand{\do@after@explicit@endgroup}{}
\def\do@after@explicit@endgroup#1#2\endgroup{#2\endgroup#1}
%
% Now the footnote command. We save the old definition, 
% used in the case where we are outside any savefoot
% environment. If we are inside a savefoot environment,
% place the "\footnotemark", and append 
% 
%    \savefoot@setcounter{<explicit number>}\footnotetext{<text>}
% 
% to our register. This will be typeset at the end. We cannot
% just do "\footnotetext[<explicit number>]{<text>}", because
% the hyperref package does not like that.
% 
\let\savefoot@old@footnote\footnote
\renewcommand{\footnote}[1]{%
  \ifnum\c@savefoot@depth>\z@
  \expandafter\@firstoftwo
  \else
  \expandafter\@secondoftwo
  \fi
  {% Inside a leftbar, save the text in the relevant toks.
    \footnotemark
    \savefoot@toks=\expandafter{%
      \the\expandafter\savefoot@toks
      \expandafter\savefoot@setcounter\expandafter{\the\c@footnote}%
      \footnotetext{#1}%
    }%
  }%
  {% Don't save, just typeset.
    \savefoot@old@footnote{#1}%
  }%
}
%
% When not using hyperref, just give the counter "footnote" 
% the right value (in that case, "\savefoot@hhyperref@support{#1}"
% will be defined to do nothing).
% 
\newcommand{\savefoot@setcounter}[1]{%
  \setcounter{footnote}{#1}%
  \savefoot@hyperref@support{#1}%
}
% 
% Getting "\footnotetext" and "\footnotemark" to work with hyperref
% is non-trivial, and I probably did something wrong. But at first
% sight it seems ok.

\usepackage{framed}
\usepackage{hyperref}
\DeclareSavefootEnvironment{leftbar}

\begin{document}

Some text,\footnote{With a normal footnote.} in which 
footnotes are preserved.\footnote{Even when you put several 
  in a row.}\footnote{Like this.}

\begin{leftbar}
  Also true for the leftbar environment.\footnote{The relevant 
    commands are placed after the end of the environment.} 
  \begin{leftbar}
    And we check that nesting works.\footnote{That was the tricky part\ldots}
  \end{leftbar}
  Maybe it breaks after nesting?\footnote{Let's see.}
\end{leftbar} 

More footnotes.\footnote{Like this.}\footnote{And that.}

\begin{leftbar}
  And another leftbar environment to be sure.\footnote{Does it 
    work? I'll see soon, when I compile.}
\end{leftbar}

[Tex/LaTex] Figure inside leftbar environment generates error “Not in outer par mode”

Use leftbar inside the figure environment. By changin the nesting you still can let it float. If you don't need floating, you don't need a figure environment: captions can be done then using the caption package (or capt-of).

\begin{figure}[h!]
   \begin{leftbar}
    \caption{Mean data points enclosed by shapes are contained within the same group, within 95\% confidence.}
    \includegraphics[scale=0.7]{"../Data Analysis Files/InteractionPlotforTransLog10(X+1)Count"}
  \end{leftbar}
\end{figure}

A solution without figure, so you can put this and everything else into an outer leftbar environment:

\usepackage{caption}
...
\begin{leftbar}
\begin{minipage}{\columnwidth}
  \captionof{figure}{Mean data points enclosed by shapes are contained within the same group, within 95\% confidence.}
  \includegraphics[scale=0.7]{"../Data Analysis Files/InteractionPlotforTransLog10(X+1)Count"}
\end{minipage}
