[Tex/LaTex] Getting \emph back to normal after loading ulem

emphasistext-decorationsulem

I'm typesetting a manuscript that is required to turn all \emph into underlines. But then I want to use the original definition of \emph for the list of references. How do I get \emph to behave like normal again?

Best Answer

Declare \normalem at the appropriate point in the document body. (The correspondent macro to switch to "underlined" emphasis is \ULforem.)

\documentclass{article}

\usepackage{ulem}

\begin{document}

Some \emph{emphasised} text.

\normalem

Some \emph{emphasised} text.

\ULforem

Some \emph{emphasised} text.

\end{document}

It's a feature of xdvi; you can disable underlining by calling

xdvi -linkstyle 0 filename

From the man page:

-linkstyle
        (.LinkStyle)  Determines the style in which hyperlinks are displayed. Possi-
        ble values and their meanings are:

         0       No highlighting of links
         1       Underline links with link color
         2       No underlining, color text with link color
         3       Underline and display text colored with link color

        The values for link color are specified by the options/resources  -linkcolor
        and -visitedlinkcolor (which see).

REVISED SOLUTION

With the recent changes in the censor package to incorporate a tokcycle-based cycle to censor the tokens, the original approach given below requires revision...in fact, it becomes much simpler.

Math censoring can occur with \mblackout (for character by character censoring) or with \mcensor (block underlining).

\documentclass{article}

\usepackage{censor}
\usepackage{xcolor}
\usepackage{stackengine}

\censorruleheight=.1ex
\newlength\maxkern
\setlength{\maxkern}{.14ex}
\newlength\nextcharwidth

\renewcommand\@cenword[1]{%
  \setlength{\nextcharwidth}{\widthof{#1}}%
  \censorrule{\nextcharwidth}%

ORIGINAL SOLUTION (based on outdated censor package)

This is a hack on the censor package to do that which was not intended. All things considered, not too bad. It makes space for descenders, with a user-settable gap (\maxkern)! The depth (\censorruledepth) and thickness (\censorruleheight) of the underrule are fully settable. It does linebreaking and page breaking. And with this EDITED version, it now does math underlining.

However, it does not do hyphenation. For text, it has two forms, using the censor syntax, \blackout (which skips over spaces and periods, and \xblackout which attempts, through the use of carefully selected measures, to fill in underlines over the blanks and periods. As the parameters are set in my MWE, \xblackout has a negative side effect of spilling slightly into the left margin.

{\raggedright\xblackout{\singlelipsum{4}}}

\[ \mblackout[3ex]{y = \frac{a^3 + b^2 + c}{d_3}}\]

\blackout{\singlelipsum{4}}
\end{document}

If space is desired between words, \blackout works real nice.

If you want the spaces to be underlined, use \xblackout. With my selection of the parameters to tune \xblackout, the underline extends slightly into both margins. Also, I am using \raggedright here, because stretching glue can make gaps form in the underline.

enter image description here

For math mode, the approach is slightly different. First difference is that it cannot make a gap for descenders (because I don't know how to convert a length variable into mu's). So, as a result, I place, by default, the math underline (named \mblackout, keeping with the censor syntax) at the depth of the \strutbox. However, for math that drops below this depth, it takes an optional argument of how far below the baseline to do the underline.

Thus,

\[ \mblackout{y = A x^2} + Bx + \mblackout{C} \]

\[ \mblackout[3ex]{y = \frac{a^3 + b^2 + c}{d_3}}\]

gives the following:

If you are afraid the underline might be confused for math division, you could always thicken it up with a change in \censorruleheight.
