This module provides a collection of utilities for working with
pretty-printers.
<dl>
<dt><code>PrettyPrinter (</code><var>name</var><code>, </code><var>subprinters</var><code>=None)</code><dd>This class specifies the API that makes &lsquo;<samp><span class="samp">info pretty-printer</span></samp>&rsquo;,
&lsquo;<samp><span class="samp">enable pretty-printer</span></samp>&rsquo; and &lsquo;<samp><span class="samp">disable pretty-printer</span></samp>&rsquo; work.
Pretty-printers should generally inherit from this class.
<br><dt><code>SubPrettyPrinter (</code><var>name</var><code>)</code><dd>For printers that handle multiple types, this class specifies the
corresponding API for the subprinters.
<br><dt><code>RegexpCollectionPrettyPrinter (</code><var>name</var><code>)</code><dd>Utility class for handling multiple printers, all recognized via
regular expressions.
See <a href="Writing-a-Pretty_002dPrinter.html#Writing-a-Pretty_002dPrinter">Writing a Pretty-Printer</a>, for an example.
<br><dt><code>FlagEnumerationPrinter (</code><var>name</var><code>)</code><dd>A pretty-printer which handles printing of <code>enum</code> values. Unlike
<span class="sc">gdb</span>'s built-in <code>enum</code> printing, this printer attempts to
work properly when there is some overlap between the enumeration
constants. The argument <var>name</var> is the name of the printer and
also the name of the <code>enum</code> type to look up.
<br><dt><code>register_pretty_printer (</code><var>obj</var><code>, </code><var>printer</var><code>, </code><var>replace</var><code>=False)</code><dd>Register <var>printer</var> with the pretty-printer list of <var>obj</var>.
If <var>replace</var> is <code>True</code> then any existing copy of the printer
is replaced. Otherwise a <code>RuntimeError</code> exception is raised
if a printer with the same name already exists.
