# \hairline

## Syntax

 \hairline

## Description

A thin rule on the baseline of its own paragraph, spanning the width of the current text.

## Example

```\setuppapersize[A6]

I had written him a letter which I had, for want of better
knowledge, sent to where I met him at the Lachlan, years ago.
\hairline
He was shearing when I knew him, so I sent the letter to him,
just on spec, addressed as follows: Clancy, of the Overflow.
% a hairline is its own paragraph,
% so \setupwhitespace will affect hairline spacing
\setupwhitespace[big]
\hairline

% A \thinrule fills out the line on which it appears.
