Using a Color Package with the Parallel Package

colorparallel

I am compiling a dual language document in LaTeX using the Parallel package. I am having trouble applying a color package to the parallel columns. For my project, I have several places where it is customary to color words or phrases of text (red in this case) to offset them from the other text. Using the Parallel package, when there is a line break in the colored text, the color spills over onto the opposite column, as in the included MWE. In the example, only the right (English) column includes a red phrase, but the color red is included in both columns of the parallel environment. This project must be compiled using the LuaLaTeX+se engine based on the requirements of other packages not included in this MWE.

If luatex is a possibility you could use luacolor =

\documentclass[12pt]{book}

\usepackage[paperwidth=8.5in, paperheight=11.0in, margin=1.5in, top=1in, bottom=.5in, footskip=.1in]{geometry}

\usepackage[latin, english]{babel}

\usepackage{libertine}

\usepackage{parallel}

\usepackage{lettrine}

\usepackage{luacolor}

\begin{document}
\begin{Parallel}{}{}
\tolerance=1000

\ParallelLText{
\selectlanguage{latin}
\setlength{\linewidth}{\hsize}\lettrine{L}orem ipsum dolor sit amet, consectetur adipiscing elit. Nullam accumsan ac lorem sit amet consequat. Nulla faucibus sed neque sit amet sollicitudin. Suspendisse ornare eros in nulla mattis, at dictum felis vestibulum. Proin efficitur lectus eu odio hendrerit, eget faucibus mi mattis.

Of course, this depends on your actual usage/document layout, but I would rather go with a tabularx layout than use the parallel package. For one, the code is structured on a line-by-line basis, rather than left-and-right chunks separated in blocks, improving readability in your code.

Here's your example, "minimimalised" for the sake of brevity:

enter image description here

\documentclass[a4paper]{report}
\usepackage{tabularx}% http://ctan.org/pkg/tabularx

\renewcommand{\baselinestretch}{1.5}\normalsize

\usepackage{geometry}% http://ctan.org/pkg/geometry
\geometry{left=3cm,right=1cm,top=2cm,bottom=2cm}

\begin{document}

\noindent
\begin{tabularx}{\textwidth}{rl@{\quad}X}
  1 & \multicolumn{2}{l}{Vertices are sorted in the following order 0,5,1,2,4,3} \\[\baselineskip]
  2 & Depth 1: \textbf{0},5,1,2,4,3 & (the bold face node is expanded) \\
    & Depth 2: \textbf{1},2 \\
    & Depth 3: \textbf{2} & Cannot expand, so $CBC$ is \{0,1,2\} with size 3 \\
    & Depth 2: 1,\textbf{2} & $d + (m - i)= 2 + (2 - 2) = 2 < 3,$ so we prune \\[\baselineskip]
  3 & Depth 1: 0,\textbf{5},1,2,4,3 \\
    & Depth 2: \textbf{4},3 & $2 + (2-1)=3 \le CBC$, so we prune \\[\baselineskip]
  4 & Depth 1: 0,5,\textbf{1},2,4,3 \\
    & Depth 2: \textbf{2},3,4 \\
    & Depth 3: \textbf{3},4 \\
    & Depth 4: \textbf{4} & becomes our new $CBC$ with size 4 \\
    & Depth 3: 3,\textbf{4} & $3 + (2 - 2) = 3 < 4$, so we prune \\
    & Depth 2: 2,3,\textbf{4} & $2 + (3 - 2) = 3 < CBC$, so we prune \\[\baselineskip]
  5 & Depth 1: 0,5,1,\textbf{2},4,3 & $1 + (6 - 4) = 3 < CBC$, as depth = 1, we stop
\end{tabularx}

\end{document}

The gap between the "Depth" and "description" is \quad.

The only drawback is that this implementation will not break across the page boundary. However, I'm not sure whether this is at all necessary.

[Tex/LaTex] How to create two column footnotes when using parallel package

The ledmac and ledpar might be overkill for your needs, but you could do something like this:

\documentclass{article}
\usepackage{ledmac, ledpar, lipsum}
\usepackage{showframe}
\foottwocolX{A}
\let\footnote\footnoteA
\parindent 0pt
\begin{document}
\lipsum[2]
\begin{pairs}

  \begin{Leftside}
    \beginnumbering\pstart
    % \firstlinenum{100}\linenumincrement{100}% <-- to 'hide' line numbers
    \lipsum[1] Aperture
    Science%
    \footnote{where GLaDOS lives} 
    \pend\endnumbering
  \end{Leftside}

  \begin{Rightside}
    \beginnumbering\pstart
    % \firstlinenum{100}\linenumincrement{100}% <-- to 'hide' line numbers
    \lipsum[2]
    We do what we must, because we can %
    \footnote{test subject} %
    \footnote{test subject} %
    \footnote{test subject} %
    \footnote{test subject} 
    \pend\endnumbering
  \end{Rightside}

\Columns
\end{pairs}

\lipsum[2]

\end{document}

Note also that you could create some commands to simplify the expectations ledmac and ledpar have regarding the starting and stopping of paragraphs and parallel columns.
