I want to get an opinion on whether people see a feature
as having any value before I investigate it further.
I've mentioned in IRC several times about an idea I had about
allowing theme inheritance or the concept of a 'fallback'
theme that would be used before falling back to default or
It's a simple concept so I worked up a patch last night to
test the theory. Basically, a theme would be allowed to
define a <fallbackTheme> tag in themeinfo.xml. The
fallbackTheme would be added to the search path before
the default-wide and default theme directories. This would
allow a themer to create variations on a theme by just
creating a new directory containing at a minimum a themeinfo.xml
This would allow a lot of different scenarios without having to
duplicate everything in the base theme, here are a couple
- Base 16:9 theme and -narrow 4:3 version
- the -narrow version could just redefine .xml and use the
images from the base
- Base theme and -blue, -red, -green variations
- the -COLOR versions could just supply some different images
or .xml depending on what colors were changing.
- Base theme and -over40 version
- the -over40 version could just have changes to the .xml to
use larger font sizes.
I think this might make it easier for new themers to play with
things because they only need to override .xml and image files,
they wouldn't have to start with a full copy of a theme and
