Rotating Alternates

Vasil Stanev · June 19

I am searching for the code that is used in a font for the following:
I want to have a font that imitates handwriting, with 3-5 alternative versions of all Latin characters, and two consecutive alternates of a letter never appear one after the other - just like the human hand rarely writes the exact same letter twice. Does the size of the set matter in regard to the code?

Grab the OT code from Caveat (3 alternates of each letter)

Think about the general pattern of what you want: if an alternate appears after the same glyph, switch it for the next alternate in the set.

Then write (or script!) that:


# When you see <alternate> <alternate>, replace the second one by <next alternate>
#
# sub <alternate> <alternate>' by <next alternate>;
#
# So for all alternates a.alt1, a.alt2, a.alt3, etc.:
sub a.alt1 a.alt1' by a.alt2;
sub a.alt2 a.alt2' by a.alt3;
sub a.alt3 a.alt3' by a.alt1;
