Is there a graphite-info.tex to find out what the feature names are in a
Graphite font?
I've haven't been able to find it and it would be useful. Or, is there
some other way to display all the Graphite features in a font.
If I remember aright, the graphite feature support in xetex shares the
same commands as the AAT feature support, so you should be able to run
the AAT-info.tex file and just change the font names appropriately.
(You'll need to change the Mac-specific fonts it uses to annotate the
output, as well as the name of the actual target font.)
My actual problem is that I have a font where the feature name is "Long
U with Yayit, long UU with Hato". I'm able to access all other features
in the font except this one. I wonder if XeTeX thinks it's too long or
if it doesn't like the comma in the feature name. Would it concatenate
the feature name in that case?
I'm pretty sure the comma is the problem; the "micro-syntax" xetex
parses in the font name string will treat comma as separating two
successive values for the same feature name. That is, it's intended to
let you say things like:
\font\x = "MyFont:Ligatures=Common,Rare,Historical"
as a shorthand for:
\font\x = "MyFont:Ligatures=Common;Ligatures=Rare;Ligatures=Historical"
To work around this, I _think_ it also lets you specify features by ID
(like for OpenType fonts), so you should be able to do
\font\x = "Padauk:+ulon"
as suggested by Andrew in the reply I just saw arrive. :)
