# \thinrule

## Summary

The command \thinrule is used to draw a line.

## Description

\thinrules are very similar to \hairlines in that

they provide means handle TeX's primitives \hrule and \vrule conveniently, or -- as the ConTeXt source puts it -- “free us from some specifications”.

The \thinrule command draws a rule on the current baseline, whereas an \hairline does exactly the same except that it creates a new paragraph for the rule alone. To the extent that the outcome of \hairline might depend on your paragraph settings and that they will always span the whole surrounding box horizontally, while \thinrules stay subordinate to the paragraph they occur inside.

The rule can be configured using \setupthinrules, but only horizontal options apply.

## Examples

### Example 1

The following example demonstrates the behaviour of \thinrule versus \hairline (MkII and MkIV).

\setupcombinations[style=\em]
\starttext
\startcombination[2*1]
{\framed[width=4cm,align=left,frame=off]{%
I have elsewhere explained,
\hairline
though it is a thing perhaps not yet well understood by all;
that the very substance of things,
consists in the power of acting and being acted upon.
\hairline}}
{Hairlines in action.}
%
{\framed[width=4cm,align=left,frame=off]{%
I have elsewhere explained,
\thinrule
though it is a thing perhaps not yet well understood by all;
that the very substance of things,
consists in the power of acting and being acted upon.
\thinrule}}
{Thinrules in action.}
\stopcombination
\stoptext


### Example 2

\setupthinrules[color=green]

{\framed[width=4cm,align=left,frame=off]{%
I have elsewhere explained,
\thinrule
though it is a thing perhaps not yet well understood by all;
that the very substance of things,
consists in the power of acting and being acted upon.
\thinrule}}
