| <h3 class="section">8.3 Management of Frame Filters.</h3> |
| <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. |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-info-frame_002dfilter"></a> |
| </dd> |
| <dt><code>info frame-filter</code></dt> |
| <dd><p>Print a list of installed frame filters from all dictionaries, showing |
| their name, priority and enabled status. |
| </p> |
| <a name="index-disable-frame_002dfilter"></a> |
| <a name="disable-frame_002dfilter-all"></a></dd> |
| <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. |
| </p> |
| <a name="index-enable-frame_002dfilter"></a> |
| </dd> |
| <dt><code>enable frame-filter <var>filter-dictionary</var> <var>filter-name</var></code></dt> |
| <dd><p>Enable 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 enabled. The <var>filter-name</var> is the name of the frame |
| filter and is used when <code>all</code> is not the option for |
