How can I make a horizontal dashed line?

Question

How can I make a horizontal dashed line in LaTeX?

Just writing lots of single dashes results in a continuous horizontal line.

Answer 1

You can look at the dashrule package, for example.

Answer 2

With Plain leaders, for example:

\def\dashfill{\cleaders\hbox{-}\hfill}
\hbox to \hsize{\dashfill\hfil}
\bye

Changing the spacing is then a matter of redefining the dashfill's hbox:

\def\dashfill{\cleaders\hbox to 2em{-}\hfill}

Answer 3

What about adding spaces between the dashes: - - - - - - ? When I try it, it works just fine. Or do you want something else?
