question about fonts.handlers.otf.addfeature

[Pablo Rodriguez]

Dear list,

as far as I know, fonts.handlers.otf.addfeature has the following types:
substitution, alternate, multiple, ligature, kern and chainsubstitution.

Is there a type of feature that simply moves a single glyph when activated?

Many thanks for your help,

Pablo

positioning

You are right, Hans.

\startluacode
    fonts.handlers.otf.addfeature {
        name = "stest",
        type = "single",
        data = {
            a = { -500, 0, -500, 0 },
        }
    }
\stopluacode

Sorry, but I forgot to consider the test suite.

Many thanks for your help,

Pablo
