How can I get vis to recognize racket files (i.e. .rkt files) and turn on scheme syntax?

Any help is greatly appreciated.

Did you find the README about lexers? It is slightly hidden.

In lua/plugins/filetype.lua, there is this section:

    scheme = {
        ext = { "%.sch$", "%.scm$", "%.sld$", "%.sls$", "%.ss$" },
    },

If you add "%.rkt$", the existing scheme lexer will be used for highlighting.

You might find the Parkour plugin useful, too. There are Racket-specific rules for automatic square bracket rewriting, among other things.
