Description

Examples

Default style and math

\underbar{This is an example. $c = \sqrt{a^2 + b^2}$}

\underbar{\input ward}

Gives:

Default style nested

\setupbar[color=red]

\underbar{A \underbar{B \underbar{Cc} b} a}
\blank

Gives:

Overstrike


Draw a rule through every line of the text.

\setuppapersize[A5]
\overstrike{This is an example. $c = \sqrt{a^2 + b^2}$}

\overstrike{\input ward}

If you are using microtypography with \setupalign[hz,hanging], then with some fonts the rule may end up off-target, above the characters instead of through them. (The problem was experienced with Linux Libertine and mkiv, and not with Latin Modern.) The workarounds are:

  • Put the overstriked text in a \inframed[frame=off]{}. Example:
\setupalign[hanging,hz]
bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla
  • Turn off microtypography for the paragraph containing the overstrike. Example:
\setupalign[nothanging,nohz]
bla bla bla \overstrike{striked} bla bla

\setupalign[hanging,hz]
bla bla bla bla bla
