[complete] [always] [compose=yes, liga=yes, tlig=yes, trep=yes] \definefontfeature [none] [mode=none, features=no] These definitions show that you can construct feature sets on top of existing ones, but keep in mind that they are defined instantly, so any change in the parent is not reflected in its kids. In a font definition you can specify more than one set: \definefont [MyFont] [Bold*always,oldstyle at 12.3pt] 4.4 @ (virtual features) This method is somewhat special as it demands knowledge of the internals of the ConT E Xt font code. Much of it is still experimental but it is a nice playground. A good example of its usage can be found in the file m-punk.mkiv where we create a font out of METAPOST graphics. Another example is virtual math. As in the beginning of LuaT E X and MkIV there were only a few OpenType math fonts, and as I wanted to get rid of the old mechanisms, it was decided to virtualize the math fonts. For instance a Latin Modern Roman 10 point math font can be defined as follows: \definefontsynonym [LMMathRoman10-Regular] [LMMath10-Regular@lmroman10-math] The lmroman10-math refers to a virtual definition and in this case it is one using a builtin constructor and therefore we use a goodies file to specify the font. That file looks as follows: return { name = "lm-math", version = "1.00", comment = "Goodies that complement latin modern math.", author = "Hans Hagen", 53 Methods
