|
<a name="index-managing-frame-filters"></a>
|
|
<p>Frame filters are Python based utilities to manage and decorate the
|
output of frames. See <a href="Frame-Filter-API.html#Frame-Filter-API">Frame Filter API</a>, for further information.
|
</p>
|
<p>Managing frame filters is performed by several commands available
|
within <small>GDB</small>, detailed here.

their name, priority and enabled status.

|
<dt><code>disable frame-filter <var>filter-dictionary</var> <var>filter-name</var></code></dt>
|
<dd><p>Disable a frame filter in the dictionary matching
|
<var>filter-dictionary</var> and <var>filter-name</var>. The
|
<var>filter-dictionary</var> may be <code>all</code>, <code>global</code>,
|
<code>progspace</code>, or the name of the object file where the frame filter
|
dictionary resides. When <code>all</code> is specified, all frame filters
|
across all dictionaries are disabled. The <var>filter-name</var> is the name
|
of the frame filter and is used when <code>all</code> is not the option for
|
<var>filter-dictionary</var>. A disabled frame-filter is not deleted, it
|
may be enabled again later.
