<h5 class="subsubsection">23.2.2.7 Disabling Pretty-Printers</h5>

<p><a name="index-disabling-pretty_002dprinters-1699"></a>
For various reasons a pretty-printer may not work. 
For example, the underlying data structure may have changed and
the pretty-printer is out of date.

   <p>The consequences of a broken pretty-printer are severe enough that
<span class="sc">gdb</span> provides support for enabling and disabling individual
printers.  For example, if <code>print frame-arguments</code> is on,
a backtrace can become highly illegible if any argument is printed
with a broken printer.

   <p>Pretty-printers are enabled and disabled by attaching an <code>enabled</code>
attribute to the registered function or callable object.  If this attribute
is present and its value is <code>False</code>, the printer is disabled, otherwise
the printer is enabled.
