No way to exclude non-game categories

[steven-sheehy]

Is your feature request related to a problem?

I'm using Redump's 3do dat to filter the 3do dumps to produce a 1g1r set. Unfortunately, the report it generates includes non-game items like coverdiscs, multimedia, video, etc. It seems like while igir does filter some categories like demos and applications, it does not support the full extent of categories supported by redumper.

I can use regex filters to attempt to exclude some by name but this is more brittle than using the <category> in the dat.

Describe the solution you'd like

I'd like the ability to include only games and exclude all other categories. This could be a new --only-games flag or the existing --only-retail could be changed to only include games by default. While new options could be added for every category to be excluded like --no-multimedia, etc., it might be easier to just focus on an only games option. Alternatively, it might be more flexible to add a flag that allows you to pass one or more enum categories like --include-categories games or --exclude-categories multimedia,video,coverdiscs.
