Rule Ammendments
Rules are the basic building blocks of Filters.
With the Release of Gramps version 5.1, the first addon Rules were released as examples of coding a Filter Rule addon. Installing similarly to any other addon, a New Rule appears as a menu item within Add Rule dialog while Defining a custom Filter.
Filters created with these Rules can tested, cloned or deleted using the Filter Editor. The dialog is invoked from the Edit menu in each Category view.
locating Filter Rule Add-Ons
The Plugin Manager can be used for more than installing & updating plug-in modules. It can help you discover the growing capabilities that might not be obvious.
Open the Plugin Manager from the Help menu and use its Search box to filter the view to only those addons which have a row or filename which include the 'Rule' term.
Add-on Rules that have been peer-reviewed will be added to Gramps' Update Manager system. This automates the installation process
When manually installed, each add-on rule's Python source code (.py
) file and Gramps Plugin Registration (.gpr.py
) file will be located in the \gramps5.2\plugins\FilterRules\
subdirectory of your User Directory
Looking at the Info on any currently installed Rule will verify the file location where add-on rules have been installed.
Add-on Rules
Families with Events with a selected role
Families • Event filters add-on rule to find Families having any Family member or shared Family level Event with a specified Event Role.
Matches people who are related to anybody matched by a person filter
People with events with a selected role
Person • Event filters add-on rule to find Person(s) having any Event with a specified Event Role.
Source matching parameters
Sources • General filters add-on rule to find Sources based on the following parameters: Title, Author, Abbreviation, Publication.
This add-on rule has similar options to the standard Filter Gramplet for the Source Category View. It can be used to save complex filter parameters. But it is also good sample code for new Developers wanting to experiment with writing add-on filter rules.
People Separated less than <N> degrees of <Home person>
Person • Relationship filters add-on rule to find Person(s) having a relationship to the Home Person within a specified degree of Consanguinity and Affinity.
The Home person is point of reference for calculating (<N>) Degrees. For N, Minimum value is 1, Maximum is value 32.
- Degree 1: person/spouse + children ( <zero N> ancestors, because the selected person is generation 1 + 1N descendants)
- Degree 2: person plus person’s parents, siblings, niece/nephew, children, grandchildren, etc. (= 1N ancestors + 2N descendants)
- Degree 3: persons grandparents and 3 generations down. (= 2N ancestors + 3N descendants).
The ancestors and descendants generations have an offset of 1 to mimic the built-in filter rule behavior.
People Separated less than <N> degrees of <person>
Person • Relationship filters add-on rule to find Person(s) having a relationship to a specified Person within a specified degree of Consanguinity and Affinity.

Developing New Rule Add-Ons
Beginning with version 5.0, Gramps implemented an database API (application programming interface) infrastructure supporting user selectable backends. This new exploration of database support lead developer to extend the add-on (plug-in) framework to support expanding Filter Rules via the Plugin Manager.
The 5.1 release changed the default database backend from BSDDB (Berkeley database) to SQLite. With the broader group of user familiar with optimizing searches, it made sense to open Gramps to the specialized knowledge.
