Hi,
For those with ftp access .. the new beta version there is somewhat
experimental as I rewrote some of the (lua) font code
- alternative basemode definitions (context only, experimental)
- cleaned up node mode initialization
No time for testing, but a suggestion I'd for a while: currently
features supported in base mode need to be registered explicitly based
on assumption that certain features tags will be used with lookup types
supported in base mode. But in practice a feature tag can contain any
lookup, e.g. I know fonts that use contextual alternates under 'liga'
tag. My suggestion is to allow any feature tag in base mode and then
check the actual type of the registered lookups (which might already be
the case).
this is somewhat tricky as basemode is a frozen approach: we set up the
ligatures once and no real analysis later on takes place
indeed checking takes place so in principle any feature that has
ligature, alternate of substitution is dealt with;
of course it's no problem to enable 'all' features in basemode, as long
as we let complaints about funny side effects go into the void; i'll
have to think about how to provide that variant efficiently
