The next version of babashka will be able to run honeysql as a library:

$ export BABASHKA_CLASSPATH=$(clojure -Sdeps '{:deps {honeysql {:mvn/version "RELEASE"}}}' -Spath)
$ bb -e "(require '[honeysql.core :as hsql]) (hsql/format {:select [:a :b :c] :from [:foo] :where [:= :a \"foo\"]})"
["SELECT a, b, c FROM foo WHERE a = ?" "foo"]
