Built-in rules vs. Add-on

[emyoulation]

Is there a way to determine and then indicate which rules are Built-in versus which are add-ons?

And will this GUI fail gracefully if a referenced Rule becomes uninstalled?

Perhaps a link to Rules help can be included in the dialog?

Built-in Rules (2 pre-existing help_url options):

• existing help button target for the Add Rule dialog:
  https://gramps-project.org/wiki/index.php?title=Gramps_5.1_Wiki_Manual_-_Filters#Add_Rule_dialog
• existing help button target for the Define Filter dialog:
  https://gramps-project.org/wiki/index.php?title=Gramps_5.1_Wiki_Manual_-_Filters#Define_Filter_dialog

Add-on Rules (Table of Contents):

• https://gramps-project.org/wiki/index.php/Rule_expansions#toc

Determining which is which is probably possible. But I don't know how to indicate that. Is there really a need for this feature?

It probably just needs a graceful way to fail.

Maybe just collate the installed rule list. Then highlight any Rules that don't correlate to those in the installed list. It could display in the same way as a missing custom filter.

The error wording probably should not 'assume' a missing add-on rule. It could be a mismatch Gramps version. A Gramps 6.x filter might have built-in rules that aren't available in 5.1 version.
