Feature suggestion: filter rule inherit

[keilmillerjr]

It would be nice to add some sort of rule inheritance for filters to keep our config file DRY (Don't Repeat Yourself). See example below of how this could work.

Code: [Select]

# Generated by Attract-Mode 1.4.0

list Arcade
layout               cools
romlist              mame
filter               All
rule                 Category not_contains *Mature*|BIOS|Casino|Fruit Machines|PinMAME|Quiz|Rhythm|Tabletop
rule                 CloneOf not_equals .+
rule                 Control contains 2-way|4-way|8-way|trackball
rule                 DisplayCount equals 1
rule                 Manufacturer not_contains <pirate>|<unknown>|<unlicensed>|bootleg|hack
rule                 Players equals 1P alt|1P sim|2P alt|2P sim|3P alt|4P alt|6P alt
rule                 Status equals good|imperfect
rule                 Year not_contains ?
filter               Favourites
rule                 Favourite equals 1
filter               Atari
rule                 Inherit from All
rule                 Manufacturer contains Atari

The Atari filter would contain all of the rules from the All filter, as well as it's own.

This would be a fantastic addition.

Ok, I'll add it to the list!

On a somewhat related noted, you can already specify default rules that get automatically added whenever a new filter gets created (just paste them from the attract.cfg file into the default-filter.cfg file in the config directory) which is useful in situations where you are always adding the same rules to every new filter created...
