8.3 Management of Frame Filters.

Frame filters are Python based utilities to manage and decorate the output of frames. See Frame Filter API, for further information.

Managing frame filters is performed by several commands available within GDB, detailed here.

info frame-filter

Print a list of installed frame filters from all dictionaries, showing their name, priority and enabled status.

disable frame-filter filter-dictionary filter-name

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

enable frame-filter filter-dictionary filter-name

Enable a frame filter in the dictionary matching filter-dictionary and filter-name. The filter-dictionary may be all, global, progspace or the name of the object file where the frame filter dictionary resides. When all is specified, all frame filters across all dictionaries are enabled. The filter-name is the name of the frame filter and is used when all is not the option for filter-dictionary.

Example:

(gdb) info frame-filter

global frame-filters:
  Priority  Enabled  Name
  1000      No       PrimaryFunctionFilter
  100       Yes      Reverse

progspace /build/test frame-filters:
  Priority  Enabled  Name
  100       Yes      ProgspaceFilter

objfile /build/test frame-filters:
  Priority  Enabled  Name
  999       Yes      BuildProgra Filter

(gdb) disable frame-filter /build/test BuildProgramFilter
(gdb) info frame-filter

global frame-filters:
  Priority  Enabled  Name
  1000      No       PrimaryFunctionFilter
  100       Yes      Reverse

progspace /build/test frame-filters:
  Priority  Enabled  Name
  100       Yes      ProgspaceFilter

objfile /build/test frame-filters:
  Priority  Enabled  Name
  999       No       BuildProgramFilter

(gdb) enable frame-filter global PrimaryFunctionFilter
(gdb) info frame-filter

global frame-filters:
  Priority  Enabled  Name
  1000      Yes      PrimaryFunctionFilter
  100       Yes      Reverse

progspace /build/test frame-filters:
  Priority  Enabled  Name
  100       Yes      ProgspaceFilter

objfile /build/test frame-filters:
  Priority  Enabled  Name
  999       No       BuildProgramFilter
set frame-filter priority filter-dictionary filter-name priority

Set the priority of a frame filter in the dictionary matching filter-dictionary, and the frame filter name matching filter-name. The filter-dictionary may be global, progspace or the name of the object file where the frame filter dictionary resides. The priority is an integer.

show frame-filter priority filter-dictionary filter-name

Show the priority of a frame filter in the dictionary matching filter-dictionary, and the frame filter name matching filter-name. The filter-dictionary may be global, progspace or the name of the object file where the frame filter dictionary resides.

Example:

(gdb) info frame-filter

global frame-filters:
  Priority  Enabled  Name
  1000      Yes      PrimaryFunctionFilter
  100       Yes      Reverse

progspace /build/test frame-filters:
  Priority  Enabled  Name
  100       Yes      ProgspaceFilter

objfile /build/test frame-filters:
  Priority  Enabled  Name
  999       No       BuildProgramFilter

(gdb) set frame-filter priority global Reverse 50
(gdb) info frame-filter

global frame-filters:
  Priority  Enabled  Name
  1000      Yes      PrimaryFunctionFilter
  50        Yes      Reverse

progspace /build/test frame-filters:
  Priority  Enabled  Name
  100       Yes      ProgspaceFilter

objfile /build/test frame-filters:
  Priority  Enabled  Name
  999       No       BuildProgramFilter
