| |
| <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| the pretty-printer is out of date.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. |
