Wolfgang Schuster:

You can apply only *one* feature to \definefontfeatures.

I've seen examples like this: \definefontfeature [fea] [mode=node,language=dflt,script=arab, init=yes,medi=yes,fina=yes,isol=yes, liga=yes,dlig=yes,rlig=yes,tlig=yes, calt=yes,trep=yes,mark=yes,mkmk=yes, kern=yes,curs=yes] so I think you mean to say that I can apply only one feature to \definefontsynonym or to \definetypeface. I tried this and it checks out. Thanks---it's nice to see hz working. Protrusion is only on the right margin?

2. As far as I can tell from trying to decode examples, there is some hidden connection between the first arguments of the second typescript block and the font switches. So, for example, a secret connection between SerifBoldItalic and \bi seems to connect Junicode-BoldItalic to \bi. Fine, but, in all the examples I've seen, there are no more than two weights and no widths. In some cases, I have five weights (light, book, medium, semi-bold, bold). How do I set up the typescript for this and the switches in the text? Must I learn more pairs like (SerifBoldItalic, \bi)?

You need more typefaces. One for light, another one for condensed etc. ------------------------------ Mojca Miklavec:

Yes, but there are not many (tf, it, sl, bf, bi, bs, sc) and I assume that they are extensible. See also below.

Maybe I'm wrong, but shouldn't it be possible (I didn't test) to modify font-unk.mkiv and add a few extra definitions to the following? (Maybe not modify font-unk itself, but just adding a couple of more definitons to the typescript.)

\definebodyfont [default] [rm] [tf=Serif sa 1, bf=SerifBold sa 1, it=SerifItalic sa 1, sl=SerifSlanted sa 1, bi=SerifBoldItalic sa 1, bs=SerifBoldSlanted sa 1, sc=SerifCaps sa 1]

You could add your in=SerifYourFontVariantName sa 1, bd=SerifYourOtherFontVariantName sa 1,

And then \definefontsynonym[SerifYourFontVariantName][YourFontName]

It's true that most people don't do that, but I see no reason for not extending the model for your particular needs.

Mojca ------------------------------ Wolfgang Schuster:

The last time i did this you needed for MkIV also

\definefontalternative[in] \definefontalternative[bd]

but be carefull with the shortcuts, \in is already used (references).

Thank you both. I want to begin experimenting with this, but there's one thing that still confuses me. If I have a font with say, forty different combinations of weight/width/shape (5x4x2), I will need to come up with forty different pairs like: myNewFontSwitch=SerifMyFontVariantName sa 1, a strain on the poetic imagination, but possible. It would be nicer though, if I could change weight/width/shape independently of each other (then I need have only 5+4+2 switches). For example, when I see something like: \rm\tf roman \it italic \bf bold resulting in: <book roman> <book italic> <bold roman>, it's surprising to see that \bf has turned off the italic---you don't expect a switch of the weight to have a hidden switch of the shape in it. Could the typescript be set up with fewer switches, so that: \rm\tf roman \it italic \bf bold would result in: <book roman> <book italic> <bold italic>, or, e.g., \rm\tf (regular book roman) \cd (condensed) \it (italic) \bf (bold) would result in: <regular book roman> <condensed book roman> <condensed book italic> <condensed bold italic>? (Also, I'm hoping that having a dozen different sets of font features won't require twelve times as many switches and feature names as this. I think there is some easier method for switching---Hans mentioned \addff{}, but I can't find anything in the docs. If that works, that would make two kinds of switches, one for some kinds of features and another for other kinds.)
